The Han army took down Xindu without any effort. After Luocheng and Mianzhu, the cities around Chengdu need to be fought, and even the Han army does not need to send troops to force it. Guangdu, Pixian, Shifang and Duan (Dujiangyan) have sent envoys to surrender. I can't wait to raise the red Han flag high again. The remaining forces of the Jin army around Chengdu were completely wiped out.

Then when Zhang Zhi returned to Chengdu, even the prefect of Wenshan appointed by the Jin court took the initiative to send a surrender letter and led the six counties of Wenshan to collectively surrender the Han army, gloriously becoming the first prefect of Jin court to surrender to the Han army.

Of course, this is a natural thing. The Wenshan Zhucheng, located in the deep mountains, must all contact with the outside world. The Han army restored Chengdu, which is equivalent to cutting off the contact between Wenshan County and the outside world. In addition, the White Horse Hu activities in Wenshan are rampant and repeatedly invaded Zhucheng in the northern part of Wenshan. If the Wenshan prefect does not surrender to the Han army quickly, and even does not need the Han army to take action, the White Horse Hu can take his head!

The rapid surrender of these cities also means that the essence of the Chengdu Plain has basically fallen into the hands of the Han army, giving the Han army more tax sources and soldiers. However, in order to win the hearts of the people, Zhang Zhi generously exempted these places from 70% of the taxes that year. At the same time, he also increased the taxes of eight liters per mu, three pounds of household silk and three pounds of mashed silk to restore the original ones of four liters per mu, two pounds of household silk and two pounds of mashed silk, and then naturally received cheers and thanks from the people around Chengdu, and sincerely supported them.

There are two reasons why Zhang Zhi dared to reduce taxes to this point. One is that after the restoration of Chengdu, various antiques and antiques were piled up in the imperial city of Shu Han. There are also calligraphy and paintings left by Liu Chan, Zhuge Village husband and son, Jiang Wan, Fei Yi and others, all of which can be sold at high prices from the system mother. These alone are enough to solve the money and food problems of the Han army for several years.

The second reason is that high-end wood is also produced around Chengdu, especially the golden nanmu that is extremely rare and expensive in later generations. Later, Zhang Zhi was extremely surprised to find that the purchase price offered by the system girl was several times higher than that of the golden nanmu produced in Yunnan and Guizhou. Then Zhang Zhi softly and threatened to learn from the system girl that the golden nanmu produced in China is the best quality and the highest price!

Upon learning of this situation, Zhang Zhi not only immediately ordered that the people of Duan use gold-silicon nanmu to deduct all taxes, but also offered high-priced purchases without hesitation. At the same time, under the guise of clearing business roads, the plan to establish cities in the Ya'an area specifically to acquire and hoard gold-silicon nanmu was of course also appeared on Zhang Zhi's book case.

With these two nearly astronomical financial sources, Zhang Zhi of course quickly fulfilled his promise when he set out in Nanzhong, and distributed all the gold, silver and money in the Chengdu treasury to the Han army soldiers, as well as the families of the fallen Han army soldiers, which brought the excitement and cheers of the Han army lecturer, and his loyalty increased again. At the same time, Zhang Zhi did not need to divide the stolen goods like Uncle Liu and became a pauper, and he had to worry about military expenditures.

As the saying goes, junk food is money, it is all kinds of military supplies. Unless the system girl really starts the self-destruction program, Zhang Zhi doesn't have to worry about both money and food.

At the same time, junk food is still a supreme temptation. After enjoying the life of the Han army prisoner-of-war camp for several days, almost all the old Shu Han soldiers who surrendered in Chengdu chose to join the Han army. Two thousand private soldiers offered by the Chang family in Jiangyuan immediately became devoted to Zhang Zhi and the Han army. After seeing the amazing food of the Han army soldiers, the men of the right age around Chengdu also enthusiastically joined the army. In addition, the local defenders incorporated by the Han army and the more than 2,000 surrendered soldiers of the Jin army who voluntarily chose to stay. On the day Zhang Zhi returned to Chengdu, the number of troops of the Han army on the Chengdu plain directly exceeded the 40,000 mark!

Moreover, even so, the Han army had not had time to start recruiting new recruits in the Xinfu Zhucheng. In addition, seeing that the Jiangyuan Chang family, the top Yizhou family, supported the Han army so firmly and received generous returns from the Han army, the Du family in Chengdu, the He family in Pi County, and the Li family in Qi County, also extended olive branches to the Han army, either offering private troops, or persuading the city of Dongguanghan to surrender, or encouraging young and strong hometowns to join the army. The Han army's plan to expand its troops to more than double within one month also quickly became within reach.

The Wuyang Yang family, another top Yizhou family who once sold his own way to help Liu Huangshu win the Hanzhong War, also had secret contact with the Han army during this period. Yang Ding, the current head of the Yang family, who had been forced to move to Wuyang City by the Jin army, arranged for his son to come forward to send a letter to Zhang Zhi. In addition to expressing his full support for the Han army to restore Wuyang, he also secretly sent Zhang Zhi the city defense situation of Wuyang City, so that Zhang Zhizu could know the height, width and thickness of Wuyang's city walls, as well as the current number of troops in the Wuyang Jin army, and the approximate defense situation.

Unfortunately, the Wuyang City Defense Information provided by Yang Ding did not make Zhang Zhi ecstatic. On the contrary, after carefully studying the city defense situation in Wuyang, the decision-making teams of the Han army such as Zhang Zhi, Yan Yu and Huo Yi frowned, and all began to worry about the next Wuyang Battle, and whether the Han army had the ability to take down Wuyang City.

Zhang Zhi and others must also worry about this. Although Wuyang City was also built on the impact plain, the city wall was relatively not particularly strong, but it was repaired and strengthened every year. At present, the thickness of the city wall has reached more than two meters, and the difficulty of excavation and blasting is far greater than that of the Chengdu city wall. At the same time, after Yang Xin led his army to retreat to Wuyang, he spent a lot of effort to repair and strengthen the city defense, hoarded an astonishing amount of materials and food to defend the city, and dredged and deepened the moat, making it extremely difficult for the Han army to overcome.

Not only that, Yang Xin had more than 15,000 troops in his hand, and Sima Wang brought thousands of cavalry, so the number of defenders in Wuyang City reached about 18,000. It was not only enough to guard the small Wuyang city with a circumference of only nine miles, but also more than enough.

What's even more troublesome is that Sima Wang and Yang Xin also learned from repeated defeats in the field and took back all their troops to defend the city. They did not build camps outside the city to station troops. Naturally, the Han army had no chance to defeat the Jin army one by one. If they wanted to annihilate the last vital force of the Jin army on the Chengdu Plain, the only way was to invade the city.

Because of this, after careful consideration, Huo Yi could only smile bitterly and said, "If you insist on saying that Wuyang City has any weaknesses, it is that the scale of the city is relatively small, with a radius of only more than nine miles. All the Jin thief troops stationed in the city must be very crowded, even more crowded than living in the military tent."

"It's a bit like the general who besieged Didao. After the Wei thief Yongzhou governor Wang Jing, he also brought more than 10,000 soldiers to hold in the small city of Didao after being defeated in Taoxi." Yan Yu said to himself: "And the difficulties we face are greater than the generals of that year. At that time, Wang Jing only had the troops to defend the city, but the materials for defending the city were not enough. Not only are we facing more defenders now, but the enemy's guarding the city had already been stockpiled sufficiently. It would definitely be more difficult to defeat Wuyang than to defeat Didao."

Zhang Zhi and Huo Yi didn't say anything, because Zhang Zhi and Huo Yi both knew that the characteristics of the soldiers in Shu were that the field was strong and the siege was weak. Whether it was the Shu army during Zhuge Liang's period or the Shu army during Jiang Wei's period, they could draw the Wei army, which was stronger than the self-armed army in the field, and they were helpless in the siege or the tough battle, so that even the tens of thousands of troops led by Zhuge Liang could not defeat Chen Cangcheng, which had only two thousand defenders.

"It would be great if the Jin thief army did not block the city gate corridor." Zhao Quan said with some whimsical thoughts: "As long as the city gate corridor is unobstructed, we can use gunpowder to blow up the city gate and then directly kill into the city."

"Impossible." Yan Yu said with a wry smile: "Sima Wang has suffered a great loss in Linqiong and will definitely learn from his lessons. Moreover, Wuyang has no urn city yet. For safety reasons, the Jin thief army must have to use earth, stone and sand bags to block the city gate corridor."

Zhao Quan shut up embarrassedly, and Zhang Zhize said with a strong smile: "No hurry, today is the tenth day of June. We took the Chengdu City on May 22nd. Calculate the time. No matter how fast the Jin thief court is, it will take more than two months to send the rear army to the Chengdu Plain. We still have enough time to calmly prepare for the attack. If it really doesn't work, we can hardly spend more effort to completely fill the moat in Wuyang, and then build more pointed wooden donkeys to directly dig down the walls of Wuyang."

"But what if the Later General, Wuyang thief army imitated Tong Ce and urgently built the inner wall in the city?" Cuan Gu reminded him with concern: "Everyone Tong Ce can think of this method to rescue the emergency, not to mention Sima Wang, who is rich in experience and far above him?"

"It's okay." Zhang Zhi cheered the Han army generals and said, "Tell you the truth. Actually, I have another kind of siege weapon that you have never seen before. It has never been used. Its power is even greater than that of a pointed wooden donkey. At worst, we can use that kind of siege weapon in advance and give the thief army a surprise."

Seeing that Zhang Zhi was confident in his words and had seen the power of gunpowder and pointed wooden donkeys that Zhang Zhi personally presided over the development and research, the Han army generals were relieved and discussed with Zhang Zhi about military expansion and preparation for war. Then they said goodbye and went back to rest, leaving Zhang Zhi to calculate in the lobby of the governor's mansion of Yizhou, and said intimately: "Do you want to get that kind of thing out in advance?"

No need to guess, what Zhang Zhi mentioned is of course the counterweight catapult, the peak of the trench machine. The reason why Zhang Zhi has not started to develop this kind of catapult is that the Han army was too weak before. If he wanted temporary benefits and made such a thing in advance, once he was learned by the enemy, it would be very likely to cause a catapult to the Han army. Now that the strength of the Han army is barely enough, he urgently needs to take down Wuyang City and pull out the nails of the Jin army on the Chengdu Plain. Of course, Zhang Zhi had the idea of ​​using the counterweight catapult.

But Zhang Zhi was still a little hesitant because Zhang Zhi did not dare to guarantee that he could successfully kill the offensive force of the Jin army in the future, and completely reversed the strategic situation that could only be a defensive counterattack, turning the strategic defensive of the Han army into a strategic offensive - if this is not done, the counterweight catapult that appears too early will of course become a nightmare for the Han army's local defenders.

In addition, Zhang Zhi was worried that even if he developed a counterweight trench, he would not be able to guarantee that he would be able to take down Wuyang City, because the weakness of the counterweight trench was too bulky, with a huge lethality but could not guarantee the correctness, and the throwing frequency was relatively slow. Zhu Yuanzhang, the founding ancestor of the Ming Dynasty, discovered in actual combat that the application effect of the counterweight trench was actually not as good as the original drag-trench trench (see "History of Science and Technology of China" Volume 5, page 179). The reason why the Mongolian army was able to win the Xiangyang City with the counterweight trench was mainly because Xiangyang was surrounded for several years, and the morale of the defenders was extremely depressed. He also saw that the counterweight trench could restrain Xiangyang's huge moat, so he took the initiative to open the city to surrender.

Considering these pros and cons, Zhang Zhi still asked Zhang Zheng to send someone to send a command to his right-hand assistant in weapon development, Li Yu, to come to see him immediately, and plan to secretly develop the counterweight catapult before talking about it. However, Zhang Zheng did not immediately sing a promise, and said carefully: "The latter general, it's half past the hour of the Youth. It's too late, and you haven't eaten yet. Should you have dinner now and see Li Cao again tomorrow?"

Seeing that it was indeed getting late outside the hall, Zhang Zhi nodded and said, "Then let's go tomorrow. Li Yu's workaholic has been presiding on the ordnance production. Now it must be more tired than me. Let him have a good rest and see him tomorrow."

Zhang Zheng, who cared about Zhang Zhi's health, was overjoyed when he heard this and asked Zhang Zhi what dinner he wanted. Zhang Zhi replied casually: "Taste me some dishes with canned braised pork and eat them with rice."

Zhang Zhi agreed and quickly sent someone to prepare dinner for Zhang Zhi. Zhang Zhi continued to think about how to attack Wuyang, and once considered using the strategy of luring snakes out of the cave to find a way to lure Wuyang Jin army out of the city to fight. However, after racking his brains, Zhang Zhi was helpless to find that unless a miracle happened or Sima Wang and Yang Xin's head was flooded, the Jin army could go out of the city and fight with the Han army with tens of thousands of soldiers, otherwise it would be impossible to let the enemy go out of the city.

After a while, he sent the dishes made of braised pork stewed with canned braised pork that Zhang Zhi paid for. However, Zhang Zhi was worried, but had no appetite and turned a blind eye to the food in front of him. He just continued to think about whether he could instigate the soldiers of Yizhou in Wuyang City. When Zhang Zheng saw it, he reminded him: "Last General, the dishes are delivered, please use them quickly. Once this braised pork is cold, it will be a thick layer of oil, and there is no way to eat it."

In the 21st century, Zhang Zhi had eaten canned braised pork more than once. Of course, Zhang Zhi knew that the broken thing was cold and solidified more lard than soup. So he temporarily put the matter behind his head and picked up chopsticks to prepare for dinner. However, when he picked up a terrible piece of meat with chopsticks, Zhang Zhi suddenly moved his heart and stopped immediately. Then, looking at the fat piece of meat covered with melted lard, Zhang Zhi quickly calculated and suddenly shouted: "Chang the price, get a basin of charcoal fire and a few cans of braised pork immediately! Quickly, the faster the better!"

Zhang Prize was confused and quickly sent someone to get charcoal and canned braised pork. Zhang Zhize thought quickly and said in his heart: "There are many people in the city, the soldiers are dense, and the drag-and-drop catapults can throw light shells. They can definitely easily throw the shells into the city. They are all rich in sulfur. There are also many reserves in Chengdu. By the way, there are still people who are white, and that thing contains a lot of phosphorus! There is a way. If it goes well, I don't need to use a counterweight catapult. I can take Wuyang City with an old catapult. I don't have to worry about being learned by Jin thieves or the Eastern Wu. They can't afford such a cost!"

After Zhang Zhi quickly put a bowl of rice into his mouth, a pot of strongly burned charcoal fire and several cans of braised pork were quickly delivered to Zhang Zhi. Then Zhang Zhi personally opened the can with a knife of Chang's price. He dug out a large piece of solidified braised pork with a knife, and threw it into the charcoal fire. The solidified pork melted when it was heated, burning rapidly, and emitting choking smoke.

Seeing this scene, Zhang Zheng and his personal soldiers were of course stunned. They didn't understand what Zhang Zhi was doing, but Zhang Zhi was ecstatic and continued to dig meat with a knife, throwing pieces of solidified lard into the charcoal basin, igniting a raging flame of more than half a person. Zhang Zhi then laughed and said, "Namoto bomb! I love you! Wuyang Jin thief, you have a good life now!!"

With a crazy smile, Zhang Zhi immediately ordered: "Chang Price, send someone to spread Li Yi immediately. Even if he is already asleep, call me immediately! Also, prepare more braised pork cans, prepare a few square iron boxes, and prepare some straw, reeds, sulfur and rags. Place them in the open area of ​​the backyard and ignite more torches. Tonight, I will develop new weapons with Li Cao overnight!"

That night, Zhang Zhi, who was extremely concerned about health care, stayed up all night without war, and neglected Chang Hong's youngest daughter, who had just been ruined for a few days by herself. Li Yi, who was called a workaholic by Zhang Zhi, also did not sleep all night. Her hair was fluffy and her eyes were covered with bloodshot and her hands were dancing and cheering.

"Scum! I didn't expect that this system not only needs to care about your food, drink, steel, but also your siege weapons. You might as well call this system the logistics manager's nanny in the future!" This was the system girl's angry roar in Zhang Zhi's mind.

The poor Han soldiers also suffered a lot from this. From the next day, the two meals of the Han soldiers' morning and evening were turned into braised pork stew with rice. Of course, it was nothing to do at the beginning. However, after a long time, some generals and soldiers still protested and asked to change the taste occasionally. As a result, Zhang Zhi just threatened that if you don't eat braised pork, you can eat the original bean porridge. The protests immediately disappeared without a trace. Fortunately, Zhang Zhi later personally invented a new way to eat braised pork fried rice and fried noodles. The poor braised pork did not completely fall into the point of disgusting Han army veterans like lunch meat.

During this period, the kitchens of each battalion of the Han army were taken over by the army designated by Zhang Zhi. The temporary Han army soldiers who drove the ducks to the shelves all concentrated the canned braised pork and melted them. Then they first removed the melted lard from the upper layer, and then added water to stew and distributed it. As for where the lard was taken, it became a secret that most Han army soldiers did not know.

What is even more exaggerated is that from the next day, the urine of the Han army soldiers was designated to be excreted into the wooden barrels provided above, and then transported to the secret camp of the Han army at the foot of Wudan Mountain. The area around Wudan Mountain was soon covered by the strong smell of evaporation of urine and it never dissipated day by day.
