Sun Ce followed Xu Shu up the mountain.

Xu Shu was riding a pair of wooden clogs under his feet, with teeth. Xu Shu took off the wooden clogs before going up the mountain and changed direction. Sun Ce saw that the wooden teeth were high and low, and they were specially made for climbing the mountain, so he couldn't help but smile.

Isn't this the legendary Xie Gong clog? Now he has invented it in advance. I don't know who has the brains. However, those who interact with the Xu family's father and son are all intellectual experts, which are all meaningless to them. Someone proposed a small invention a few years ago and sent it to him. He was shocked and immediately told the man to keep it secret and must not be circulated outside.

It was a pair of stirrups. Although the shape was slightly different from that of later generations, its function was completely satisfied.

The lack of horses in Jiangnan, and riding horses is a big challenge for the people in Jiangnan, especially the movements of riding horses have stumped many people. With the increasing improvement of cavalry armor and the emergence of horse armor, heavy cavalry has gradually become a trend. In order to ensure that the cavalry can sit firmly on the horse's back, the saddle bridge is getting higher and higher, ensuring the stability of riding, and it also creates greater difficulties for riding horses. The invention of stirrups is imminent.

In fact, Taishici reported that Yan Rou had proposed the idea of ​​stirrups, but considering that the stirrups were simple and had excellent results, it was almost inevitable that they would be imitated. So he never announced that he had made a large number of stirrups, but only allowed a small number of cavalry to try them out. The others were hidden in the arsenal, waiting for the critical moment to be taken out as secret weapons, and a battle would be a decisive battle.

But Sun Ce doubted how long this secret could last. After all, the demand for stirrups is very strong and it is not complicated to invent. If one person thinks about it, others may think that now there are wooden schools in counties and counties, and some workshops with strong and vision have begun to hire skilled craftsmen and organize personnel to conduct technical research. There are many big ideas. Inventing stirrups only requires a wedge machine.

For the first time, Sun Ce felt that technology promotion was not a good thing.

“Who did it?”

"I forgot what his name is, Mrs. Huang may know that Ge Xuan said that the child had just been admitted to the Wood School."

"Have Ge Xuan been here?"

"Well, let's discuss a comparison of a elixir recipe with my father. My father is not good at this, so I introduce him to find Zuo Ci."

"Pill recipe?" Sun Ce was interested. It was not black gunpowder. Although he had not done any related work, he was more concerned about these Taoist priests who refined alchemy. Wei Teng's brother Wei Ao, Wei Boyang, has been among his attention, but he has not had the chance to meet. He has always thought about how to attract these Taoist priests who refined alchemy to the chemical aspect, just like Qing Jian. Qing Jian was also an expert in alchemy, but now he is an expert in dye research and has an indispensable contribution to Jingyu's textile industry. "What kind of elixir recipe?"

Xu Shu lacked interest. "I can't remember it clearly, it seems to be related to the technique of sylling gold."

Sun Ce smiled. "Next time he comes again, you ask him to come to me, I know a little about this."

"Here." Xu Shu glanced at Sun Ce, not surprised.

While chatting, the two went up the mountain and came to the gate of the courtyard. Xu Yue stood at the door to greet him. He had gray hair and had not combed it. He simply tied a bun, but was in good spirits and his eyes were shiny. As soon as he saw Sun Ce, he came up and bowed with a smile.

"King, I have found the way."

"Let me tell me." Sun Ce touched his nose, feeling helpless. "I hope I can understand."

Listening to Xu Yue’s explanation of math may be a feast of thinking or a painful torment. It depends on whether you can understand it. If you understand it, you will be enlightened and suddenly enlightened. If you don’t understand it, you will be a bucket of mucus. The more you listen, you will be confused. The terminology and methods of math in this era are completely different from the mathematics he has learned. He does not have an advantage over others. He is standing at the same starting line or a backward position. For a barely metaphor, just like Olympiad mathematics, not everyone has that IQ. If you can solve the problem with equations, it does not mean that you can understand that clever way of thinking.

He obviously has no talent in mathematics.

"Oh." Xu Yue also knew Sun Ce's mathematical level, and did not expand it, and went straight to the topic. "I repeatedly deduced and found that the trajectory of the sun and the moon may not be perfect, and it was a bit off-center. According to this idea, I re-deduced the existing solar eclipse record and found that there may be a solar eclipse on the first day of September this year, right... "

"Wait." Sun Ce interrupted Xu Yue. He was not very concerned about when the solar eclipse was. To him, the solar eclipse was just an astronomical phenomenon and had nothing to do with the human world. But Xu Yue found that the orbit of the sun and the moon was not a perfect circle, which was more valuable.

"King?" Xu Yue looked at Sun Ce with a blank look on his face.

"What does it mean to be a little biased?"

"A little biased... just a little biased." Seeing Sun Ce laughing strangely, Xu Yue scratched his head and looked forward a little more. "Would you... know a little about it?"

"No, no." Sun Ce knew that his mathematics was taught by the physical education teacher. He couldn't even remember the elliptical formulas clearly, so he wouldn't be ugliness. Let the Xu family and his son think about it themselves. In terms of IQ, the father and son would definitely crush him, not to mention that Yan Yan and Zhao Ying helped him, and it would be a matter of time before deducing the elliptical formula.

Is the salary of 2,000 shi so easy to get?

"You invited me to come because of this discovery?" Sun Ce continued to walk in.

"Of course not. I just said that there may be a solar eclipse in September this year. King, as far as the disasters and dissatisfaction of the five elements are concerned, the sun is the monarch and the moon is the concubine. The solar eclipse means that the strong minister will be the lord or the harem will interfere in politics. King, don't worry, I know you don't believe it, and I don't believe it, but there are many people who believe it. It's good to know it earlier and take some precautions, right?"

Sun Ce stopped, looked at Xu Yue with a sincere face, and smiled. "You don't believe me, Mr. Xu?"

"Uh, I originally... I believed it a little, but now... I basically don't believe it anymore." Xu Yue let go of Sun Ce's sleeves, scratched his fluffy white hair, and laughed like a child: "Since I can calculate it and it is inevitable, it should have nothing to do with people. However, there are few wise people, many fools, and there are many people who believe in it. It is even more difficult to guarantee that someone will use the celestial phenomena to speak and deceive people's hearts..."

Sun Ce understood it. This was something that reached Xu Yue. Xu Yue was quiet and could be heard. The words that could be reached by him were either intentional or public opinion was already sensational, but he just didn't know it. For him, the possibility of the latter did not exist, only the former, and someone had come to visit Xu Yue.

"for example?"

"Well, there is a fellow minister in Shu who said he had also calculated the solar eclipse in September, and that there was something happening in the southeast. He didn't say anything about it. The celestial phenomena are always mysterious and difficult to understand, and you can explain it no matter how you explain it."

"Shuzhong?" Sun Ce pondered for a moment. "There are such masters in Shuzhong?"

Xu Yue shook his hand, full of confidence. "I can't be considered a master. The time difference is several hours, and it's not as accurate as my algorithm."

Sun Ce couldn't help laughing loudly.

"Solar eclipse?" Guo Jia smacked his lips, feeling a little regretful. "What does this have to do with my country of Wu? We are not bullying him, we are going to replace him."

Sun Ce almost sprayed out the soup that had just been drunk in his mouth with a "pop" sound. He took a lot of effort to swallow the soup and blamed him: "Fengxiao, pay attention to your words."

"Hey, right." Guo Jia shook the feather fan and said, "Master, I am really disappointed. When has it been, and I still use this method of being unable to get on the table. Once Xi Zhicai died, will there be no one under Cao Cao's command? The Fa Zheng you mentioned is not so incompetent, right?"

Sun Ce didn't say anything. Xi Zhicai died, and Fa Zheng took over Xi Zhicai's position and became Cao Cao's planner. I don't know if it was Xi Zhicai's exhaustion that made Cao Cao worry that Fa Zheng would repeat the same mistake, or if he felt that Fa Zheng's talent was not as comprehensive as Xi Zhicai. Fa Zheng was only responsible for military strategy, and his official name was military strategy, which was not the way that Xi Zhicai led to control the overall situation. Fa Zheng's ability should be the confrontation between the two armies, not this kind of public opinion. Creating public opinion with solar eclipse is indeed not like Fa Zheng's means.

"No matter who is the means, just be prepared to deal with it. When fighting a battle, whoever is afraid of whom?" Sun Ce waved his hand and ended the topic. For him, there was no need to discuss such a thing, just arrange Lu Cui and the others. "Tell me the latest news."

Guo Jia responded, brought several military newspapers and placed them in front of Sun Ce. "Two things are more urgent: one is that the Li family of Juye betrayed Cao Ang, based on Zhencheng, and seized Dingtao. Cao Ang's defense line may collapse; the other is that the emperor appointed Dong Yue as a former general, and the main force advanced eastward, and it is possible to go to Hanoi and attack Henan."

Sun Ce put down the soup bowl, picked out the two military newspapers, and spread them out and looked carefully.

There are traces to this when the Li family of Juye betrayed Cao Ang. In the battle of Rencheng, Li Qian and Li Chi were killed in battle. The Li family was severely injured. The Li family of Juye made a grudge with him and was waiting for the opportunity to take revenge. Now that Yuan Tan is making a comeback, Cao Ang chooses to fight Yuan Tan. Li Jin and Li Dian feel that there is no hope of revenge. Taking advantage of Cao Ang's adjustment of the defense line and insufficient troops, it is reasonable to raise the flag to support Yuan Tan. The court launched Yizhou, Jizhou and Youzhou to besiege the Central Plains. The situation was indeed grim. Not many people who still had confidence in him. The only one who chose Yuan Tan for the Yanzhou family was not the only Li family, let alone Li Jin and Li Dian had a grudge.

He didn't care whether Li Jin was smart or not, but Li Jin's occupation of Dingtao had a great influence, so Cao Ang lost his power and the front line might be pushed to Yuzhou, which is indeed not good news.

What he couldn't understand the most was Dong Yue, or to be more precise, Jia Xu behind Dong Yue. What was the idea of ​​this old fox? Dong Yue not only let the emperor enter Hedong, but also became the emperor's forward. Is he determined to support the emperor, or has another plan?

Bingzhou was handed over, Hedong was handed over again, military power was gone, and territory was gone, what other means did Jia Xu have to use?
