In the center of the room, there is a large bed frame with three huge bows, various bow strings, ropes, and wheels, which looks very strange.

Wang Yuan did not hide anything: "This is called the Three-Gong Crossbow. It was made for the soldiers guarding Longtou Pass. I hope it can help them repel the deserters!"

Wu Ling's eyes lit up: "I didn't expect that Mr. Master is also proficient in craftsmanship. How many people can draw this Sangong bed crossbow and how far it can shoot."

Wang Yuan thought for a while: "It can shoot a thousand steps, and one person can control it!"

Wu Ling was shocked: "Can you give it a try?"

Daye also has a giant crossbow, which fires a big arrow at a time and can shoot three hundred steps away, but it takes twenty people to pull it apart.

After three attempts, the twenty men were exhausted and could no longer fire the crossbow.

If someone said this, he wouldn't believe it at all!

But a friend said that Mr. Mingtan made a strange thing in Lao Feizhuang not long ago.

A salt well dug in one day is as deep as a family's trench and it takes a year.

Creaking...

Without saying much, Wang Yuan turned the winch and pulled the string pulley, and the three giant bows were pulled apart little by little. Then he placed a giant arrow and fired it towards the courtyard wall.

Boom!

The one-foot-long brick wall collapsed suddenly, shocking the people in the yard.

Wu Ling was stunned: "This is too powerful!"

“I can only say it’s okay!”

Wang Yuan was a little dissatisfied.

The three-bow bed crossbow is the strongest bed crossbow in the Song Dynasty of China. Its principle is not complicated.

But if you want to pull it apart, you need seventy people.

When he was in college, he worked on a small project to modify the three-bow bed crossbow.

Using modern computers, the bed crossbow structure has been optimized to make it more in line with mechanical design, and a winch and pulleys have been added for ease of use.

However, the pulley winch here is not smooth enough, and it is still a bit laborious for one person to operate.

"Sir, you are too modest!"

Wu Ling said with surprise: "I was originally worried that it would be difficult to hold on to Longtou Pass. Now that we have this divine crossbow, it should be safer."

Wang Yuan was shocked: "Can't Longtou Pass be defended?"

"Longtou Pass is impregnable. Logically speaking, it can be defended!"

Wu Ling's eyes were worried: "But King Tu Nan is an old fox. He is very thoughtful and cunning. Although my father defeated him, he failed to keep him. Since he decided to launch an army, he must have a plan. The guard of Longtou Pass is Ruan Chenggang.

, he has more than enough to defend, but not enough to adapt to the situation, I'm worried that he won't be able to defend!"

Wang Yuan was surprised: "Isn't the commander of Longtouguan Xue Pan? Why did the guard become Ruan Chenggang?"

Wu Ling smiled bitterly: "Sir, you don't know. Although Xue Pan is the commander, he is not guarding the front line. He has been staying at the commander's residence in the county!"

Wang Yuan was astonished: "The barbarians are all here. What is he, a commander, doing in the county and city if he is not directing operations at the front lines and boosting the morale of the troops?"

Wu Ling chuckled: "There are two categories of great generals. One is hereditary nobles like Xue Pan, who are appointed by the imperial court as official posts. The other is my father and Ruan Chenggang, generals from humble families who fought on the battlefield, and the imperial court appoints them.

As a deputy, it can be regarded as a mutual restraint. The nobles cannot bear the hardships on the front line, and they are all generals from poor families commanding the front line, and they are stationed in neighboring counties and cities!"

"..."

Wang Yuan was speechless.

There is no long-distance communication, and the powerful principal is not on the front line, leaving the deputy to command from the front!

No wonder Daye has never been able to defeat Huangren, even if the gods come with this kind of arrangement!

"Sir, in order to find you, I went to Wang's house specially!"

Wu Ling added: "I heard from my dear brother Zhonglou that sir, in addition to being proficient in manufacturing, you are also proficient in the art of war. You defeated the Three Tigers Village, Daqingling, and Yixiantian in a row. You are like a god with your troops. I would like to ask you for advice on the art of war!"

"I don't understand the art of war. The ones I fight are all bandits. Don't listen to Chonglou's nonsense!"

Wang Yuan waved his hands repeatedly.

After staying in Lao Feizhuang for a few days, Wang Chonglou heard that they had many things going on.

Wu Ling clasped his fists and said with a smile: "Sir, you are being too modest. I heard from Chonglou that in those three battles, although he fought bandits, he was very good at arranging troops and understanding the enemy's intentions. He can be called a master in the art of war. Please give me some advice."

.”

"I really don't understand the art of war, and I can't fight!"

Wang Yuan waved his hands repeatedly. Seeing that Wu Ling didn't believe him at all, he couldn't help but said with a headache: "I defeated the bandits three times, and I took advantage of an information gap!"

Wu Ling frowned: "Lack of information?"

Wang Yuan said with a headache: "It's because of the asymmetry of intelligence. I know their strength, but they don't know my strength. I concentrated my strength, and they dispersed it."

"The intelligence is asymmetric! I understand, sir. What you mean is that soldiers are cunning. When fighting, they just disguise themselves to prevent others from seeing through!"

Wu Ling's eyes lit up: "When you are strong, you can pretend to be weak, introduce the enemy to ambush, and fight a battle of annihilation; when you are weak, you can pretend to be strong, intimidate the enemy, and make them dare not act rashly. To sum up, always concentrate your strength and create a favorable environment.

Try to destroy the enemy and save yourself!"

"..."

Wang Yuan was stunned and nodded: "Well, not bad!"

Wu Ling cupped his fists and bowed his head: "Thank you sir for your advice. The students have benefited a lot. There is one more thing, sir, please consider it!"

Wang Yuan frowned: "You said?"

Wu Ling said seriously: "If one day, the students can take charge of the army again, I hope to worship you as a military advisor, sweep away the barbarian countries, and restore peace to the world!"

When Wang Yuan heard this, he waved his hand: "I have no interest in fighting. I will leave Jiushan County after I make a few more three-bow crossbows!"

Wu Ling sighed in surprise: As expected, Sir has no intention of serving the imperial court.

…

"Fire the arrow!"

"Pour hot oil on it!"

"Pour golden juice!"

"Smash rocks!"

"Kill!"

The faucet was turned off, a rapid voice shouted, and groups of soldiers ran around!

The city walls were covered with torches, and large pots were set up, burning hot oil and golden juice with a stinking odor.

There were also soldiers carrying burdens and carrying baskets of stones up from under the city wall.

There were even soldiers carrying bundles of feathered arrows and filling empty quivers for the archers.

The soldiers kept moving, and no desert soldier was able to attack the city.

This offensive momentum has lasted for two days.

Under the city wall, there was a thick layer of dead people, but there were still desert soldiers climbing up on engineering ladders covered in blood, their eyes full of fear and numbness!

Not far away, in the distance, is the Human Supervisory Team, and the Huangren Iron Cavalry further out.

"What on earth does King Tu Nan want to do, to attack the city like this!"

"For two days and two nights, I kept attacking the city with great cause and sinned the people. I didn't even get to the elite of the deserters!"

"The people who have committed crimes like this are here to die. It is impossible to capture the city."

"Is it possible that he wants to use these cannon fodder to exhaust our available strength, and then use the elite deserters to attack."

"But this is simply impossible. I have 30,000 troops here, and my combat power will not be reduced at all under rotation!"

"What on earth does he want to do!",

Looking at the black and overwhelming army of deserters, deputy commander Ruan Chenggang paced on the city wall, muttering back and forth.

The name of a person, the shadow of a tree, and the evil name of King Tu Nan make every great cause fearful.

This is obviously a useless cannon fodder siege, not like the work of a famous general at all!

Suddenly, two battalions of soldiers went upstairs, and someone shouted: "Brothers, change the defense!"

The soldiers who had been defending the whole day were all relieved and began to descend from the tower one after another.

A battalion of 5,000 men changed defenses and continued to shoot arrows, throw stones, pour hot oil, and pour gold juice.

Ruan Chenggang couldn't help but nodded.

There are six battalions in Longtou Pass, each battalion has 5,000 people and is led by a general!

The six battalions took turns defending the city, once every three days, to maintain strong combat effectiveness.

King Tu Nan wanted to use his great cause to sin against the people and consume their fighting power. It was simply a wishful thinking.
To be continued...
