Physician of the Song Dynasty: Zhang Kai and Li Qingzhao have a private life-long contract

"The method of building a city can control Xixia!"

In an instant, all the officials looked at Fan Zheng with dissatisfaction. At this moment, Fan Zheng was still thinking of doing evil.

Xixia is a stubborn problem that has caused headaches for the Song Dynasty for decades. If we could rely on the city to resist Xixia, why would we wait until today?

Moreover, the Song Dynasty's city-building methods were extremely mature. Even so, the city was still attacked many times by Xixia, which was a heavy loss. They did not think that Fan Zheng could double the city's defense power with just one evil plan.

Fan Zheng said proudly: "Fan's city-building method is not a common city in the Song Dynasty, but a military castle. If Jinming Village was built according to Fan's city-building method, it would probably have a different ending."

Zeng Bu, the Privy Councilor, had disgust on his face and said, "Fan Taicheng is lying and telling lies. Does he know that he is guilty of deceiving the emperor?"

Fan Zhengyi said without fear: "Fan naturally knows the crime of deceiving the emperor. However, if you all understand Fan's method of building the city, this method of building the city will be unbreakable and it will be difficult for Xixia to move forward."

"It's hard to move even an inch."

All the officials in the court looked at Fan Zheng as if they were a fool, and they didn't believe Fan Zheng's words at all.

Only Zhao Xu was looking forward to it, because Fan Zheng's evil methods never let him down.

"Then I will listen attentively to Fan Taicheng's suggestions for building the city." Zeng Bu sneered in his heart. Today he would reveal the true face of Fan Zheng's talk on paper and make the officials completely disappointed with Fan Zheng.

"Bring a pen and paper." Fan Zheng said solemnly.

Zhao Xu waved his hand, and Tong Guan immediately presented him with paper and pen.

Fan Zheng took the pen and paper, carefully measured the paper, and then solemnly drew the most classic Vauban bastion in later generations.

Lu Dafang immediately sneered and said: "General Fan Taicheng made the fort look like a hedgehog. Do you think it will make Xixia unable to eat it?"

Zeng Bu also shook his head and laughed: "Fan Taicheng's city building is magnificent in shape, like a star, but it is flashy. Not to mention that resistance makes it difficult for Xixia to move forward, it is simply vulnerable."

He is a man who knows how to fight. When he saw the blueprint of the fortress from his perspective, he already thought of several ways to break the city.

"This fort is completely just an idea on paper. It has several protruding corners. It is simply superfluous. It allows the enemy to increase the breakthrough surface out of thin air and increases the risk of breaking the city." Yushi Yang Wei was extremely sarcastic about Fan Zheng's drawings of the fort. Although he was a scholar, , but we also know that the fewer the city walls, the fewer places the enemy can attack, and the easier it is to defend. The sword pavilion that cannot be opened by one man is the best example.

However, Fan Zheng's bastion drawing goes in the opposite direction, using sharp corners to actively increase the length of the city wall. Isn't this looking for death?

All the officials in the court were also disappointed, shaking their heads and sighing.

Zhao Xu looked embarrassed. Although he didn't understand military affairs, he also knew that this kind of castle might not be able to withstand the Xia army's attack.

Fan Zheng did not panic at all, and solemnly nodded and said: "This method of building a city is called a bastion. A protruding bastion will increase the risk of breaking the city, but it will also increase the number of attack points for the defenders, allowing the defenders to attack. Strength is doubled.”

Zhao Xu's heart moved. An ordinary city wall is just a flat surface and can accommodate limited attack points. However, the sharp corners of the bastion are enough to greatly increase the number of defenders that the bastion can accommodate.

"It's just borrowing the idea of ​​a horse facing a wall! It's nothing new in the Song Dynasty." Lu Dafang sneered. The horse-faced wall is a masterpiece of the Song Dynasty's defense system. The city wall projects an arch outward, like a horse's face, which greatly increases the defensive power. The same principle applies to the towers, which increase the height and increase attack points.

Fan Zheng nodded and said: "The principle of the bastion is indeed similar to that of the horse-faced wall. However, the horse-faced wall is still the concept of full defense of the traditional city wall, while the bastion is different. It advocates attack as defense."

"Using offense as defense?" The officials couldn't help but frown. The cities all exist for defense, so there is no need to use offense as defense.

“For both sides of the siege in the past dynasties, the defender had the advantage of occupying the city, and the siege had the advantage in military strength. The bastion greatly increased the length of the city wall, increased the defender’s strength, and limited the separation of the siege’s strength. Let the military strength of the defenders and the siege team be not much different. If the defenders add a weapon, it will turn decay into magic, and turn such a city that seems to be full of loopholes into a terrifying killing machine. .”

"What kind of weapon is it?" Bai Guan couldn't help but asked curiously.

"God's Arm Crossbow!" Fan Zheng said word by word.

"God's Arm Crossbow?" The officials were shocked. The God's Arm Crossbow was the most powerful weapon in the Song Dynasty. The weapon originally came from Xixia, which caused the Song Dynasty to suffer a lot. During the Shenzong period, the Song Dynasty finally obtained the God's Arm Crossbow. Drawings, manufacturing a large number of equipment for the entire army, and becoming one of the military's magic weapons.

According to records in the history of the Song Dynasty, the divine arm crossbow used the body of the divine arm crossbow, the sandalwood as the bow, the iron as the head of the gun, the copper as the hair of the horse's face and teeth, and the hemp rope tied with silk as the string. The length of the bow is two inches per three feet, the string length is two feet and five inches, and the arrow wood feathers are several inches long. It can shoot more than three hundred and forty steps, penetrate half a knot of elm wood, and can break heavy armor.

"My lords, just imagine that all the protruding parts of the bastion wall are filled with crossbowmen holding divine arm crossbows, because the siege soldiers on either side will be attacked from two or even three sides, and with the terror of the divine arm crossbow With the lethality, any enemy attacking the bastion will suffer more than ten times the casualties. Theoretically, as long as there are enough divine arm crossbows, the bastion will never fall." Fan Zheng raised his arms and roared.

The bastion appeared as a product of the alternating era of cold weapons and hot weapons. The best weapon for the defenders was the matchlock. However, the power of the divine arm crossbow was comparable to the matchlock and completed the task of firepower output.

"The bastion never falls."

The eyes of the officials suddenly changed from disdain to serious expressions. Especially, Zeng Bu, the Privy Councilor who knew the soldiers, had long lost his previous contempt and carefully deduce on the bastion drawing. However, the more he deduce, the more shocked he became.

The traditional method of defending the city can only attack the enemy's front, and is often blocked by the siege's shields, with little effect. However, the addition of the bastion and the divine arm crossbow will infinitely expand the defender's advantage, and all siege parties can It will withstand heavy crossbow attacks from the left, right and even the back, killing incoming enemies in large numbers!

"What a bastion! What a defense instead of attack!" Zeng Bu suddenly exclaimed.

The traditional method of using attack instead of defense means taking the initiative and rashly increasing the risk of defeat. However, the bastion uses attack instead of defense to defend the city, abandoning the traditional passive method of defending the city and using the powerful divine arm crossbow. In the future, if the enemy is killed under the city wall, let alone climbing the city wall, the enemy will suffer huge casualties even if he is close to the city wall.

"Zeng Aiqing thinks the bastion strategy is feasible?" Zhao Xu turned from surprise to joy and asked quickly.

Zeng Bu nodded solemnly and said: "This bastion is indeed an ingenious work. If you are equipped with enough divine arm crossbows, you will have to pay at least ten times more casualties if you want to break this bastion."
