Human beings are always improving, and after Zhang Jiao's Heavenly Soldier Heavenly Spell was broken by the black dog's blood and filth, Nanhua Lao Xian invented some more spells. Among them, the technique of wind, thunder and rain is to guide the external world in nature from the inner scene in the human body, and use the principle of resonance to operate the inner scene of the human body that can be guided by the mind, so as to affect the climate change of the outside world and produce wind, clouds, thunder and lightning.

This is a real spell, and it takes mana to be able to perform it.

Of course, if it is rainy weather, this can do more with less; In the windy and sunny weather, it will be half the effort.

Therefore, Wang Daochang regrouped and cast another spell. But it didn't work well.

It was true that there was wind and thunder blowing towards the city wall, but the wind was not strong, and Yuan Jun could stand firm with his spear. Later, a light rain also fell, and it only drenched the soldiers of the Yuan army. There is no more terrible power of flying sand and rocks.

Cao Cao had no choice but to collect his troops and set up a large camp five miles outside the city.

In this way, the form becomes stalemate again. Yuan's army could not go out of the city to fight, and Cao Cao could not attack the city. Yuan Shao and Cao Cao were both worried, and Cao Cao was more serious, because his food was limited and he couldn't hold on.

Liu Ye has a way, he said: "Yuan Shao kills horses and dogs, horse blood and dog blood can reduce the heavenly soldiers and generals to paper people." But the wind and rain can't stop it, and it can determine an area, only blowing in the direction of a fixed area, Yuan Shao can only defend. In this way we are invincible. ”

Cao Cao was a little happier when he heard this. If it weren't for the lack of food and grass, if the confrontation continued, he would have won.

Liu Ye said: "I have seen the stone throwing car in Liaodong, and I have thought it through this time. Now I can build a more powerful thunderbolt that can break down walls. When the time comes, with the cooperation of the royal governor and the generals, we can break Yuan Shao in one battle. ”

Cao Cao was overjoyed and ordered the construction of a thunderbolt; He also fed the soldiers and prepared to draw Yuan Shao in a battle.

The so-called thunderbolt car is Liu Ye smearing gold on his face. It is the rock-throwing truck of Liaodong restored. Due to its lever principle, the stone thrown after lengthening becomes larger, but the power is also limited.

In recent years, Liaodong has used spring steel sheets as power to turn the lever stone thrower into a winch stone thrower. The new generation of catapults can already throw kilometers away; The power at 300 meters is several times greater. However, Gongsun Kang ordered this weapon of mass destruction to be hidden, and prepared to be used on the battlefield in the event of a large-scale decisive battle.

However, Liu Ye is indeed talented, he not only restored the catapult, but also improved the Eight Bull Crossbow. The three-bow bed crossbow was made. This time, he will also show his skills in siege warfare.

In a three-bow bed crossbow, the direction of the rearmost bow is opposite to the position of the other two bows, which can increase the stroke of the string, increase the rebound of the bowstring, and increase its power.

But Liu Ye did not add two small pulleys to reduce the friction of the bowstring; The bowstring is also not made of whale tendons. This is also the core secret of the fourth-generation bed crossbow in Liaodong. The fifth-generation bed crossbow in Liaodong even changed the bow arm to a multi-layer leaf spring superposition. It really became a big killer.

Cao Cao's army was busy preparing for five days. On the sixth day, he came to the foot of White Horse again.

This time, he didn't fight the generals, and he didn't let Wang Daochang cast spells.

In front of Cao Cao's army, dozens of catapults and dozens of bed crossbows were lined up.

The catapult was aimed at the city wall, and the bed crossbow was aimed at the city gate. The city gate was narrow, and Liu Ye ordered the bed crossbow to adopt a three-stage shooting method, and each batch of ten bed crossbows was fired at the same time.

In front of the stone-throwing cart and bed crossbow, there are 3,000 heavily armored soldiers with helmets and armor, holding long knives, responsible for guarding the siege equipment.

Does it look familiar, it is the tactics of Liaodong. Liu Ye has learned a lot.

Everything was in place, and Liu Ye ordered: "Stone-throwing car, launch!" ”

Dozens of stone-throwing trucks began to throw large rocks one after another. Each catapult was loaded with twenty leather ropes, each of which was held by twenty sturdy soldiers. They were all shirtless, their muscles bumpy, and they glistened in the sun.

After five days of training, these soldiers were able to move in unison, following the commander's command, "One, two, three, drag!" ”

The soldiers pulled down the leather rope in unison, and the stone at the other end was thrown against the wall.

The principle of this catapult is to use human power to pull the tips (cannon tips) attached to the crossbar at a distance from the catapult. The gun ends are erected on a wooden frame, one end is tied with a rope to the holster that holds the stone projectile, and the other end is tied with many ropes for the force to pull and throw the stone projectile.

Dozens of large stones weighing about 100 catties smashed on the city wall, and the city wall shook a few times. White Horse Castle is still an old-fashioned earthen wall, and it is not very high. Yuan Shao did not strengthen it at all, it was still the same as before the occupation.

Liu Yan, the Taishou of Dongjun, pointed out beside Liu Ye: Where is the weak link in this section of the city wall, it has collapsed and was repaired later.

Liu Ye instructed the catapult to aim at the part of the city wall pointed out by Liu Yan and focus on launching.

It was not Yuan Shao's character to be beaten and not fight back, and he ordered the general Chun Yuqiong to take 5,000 cavalry out of the city and destroy the stone throwing cart.

The city gate creaked open, and 5,000 cavalry began to attack, and the general Chun Yuqiong took the lead and bravely ran ahead.

Liu Ye smiled coldly and ordered: "Batch A, shoot!" ”

More than 100 cavalrymen of the Yuan army had just come out of the city gate and were running onto the drawbridge.

The first bed crossbows, the ten crosses began to wield together. Ten black iron spears, with a buzz, shot out. The cavalry on the drawbridge was skewered with meat skewers!

Each bed crossbow shot through three horses, or seven or eight people, before it stopped.

The leading general, Chun Yuqiong, is in the list of the first batch of martyrs who died heroically. A crossbow shot him through the front and back, through the front of the chest and out of the back. Before he could understand what it was like, the corpse had fallen to the ground, and a horse behind him was also shot, and Hu Teng pressed on Chun Yuqiong's body with a bang.

And that's not all, the second and third batches of crossbow arrows began to fire again, and along the city gate, they actually shot into the city!

5,000 soldiers, less than 500 people just out of the city, were washed by crossbow arrows. 30 bed crossbows, shooting them to pieces.

The follow-up soldiers, seeing the tragic scene of the martyrs in front of them, never dared to go out of the city again. He did not dare to return to the camp, but only lingered inside the city gate.

Under the throwing of several waves of large stones, the city wall fell with a clatter.

At this time, Wang Daochang began to exert his might, the black gas was rolling, flying sand and stones, and the heavenly soldiers and heavenly soldiers would fall from the sky. The blood and filth of the horses that had been prepared on the walls were buried in the earth. Yuan Jun had nothing to break this spell for a while, so he could only retreat and leave the vicinity of the city wall.

Cao Cao was overjoyed and hurriedly ordered his soldiers to fill the moat with the sand and soil that had been prepared, preparing to attack the city through the gap.

Yuan Shao had no choice but to withdraw his troops.

He has a good face and does not want to make peace. So when retreating, he was killed by Cao Cao, and several generals after the break, Wei Yuanjin, Han Juzi, and Lu Weihuang all died or were captured and surrendered (He Mao, Wang Mo), but fortunately, Yan Liang, Wen Chou, Han Meng, Jiang Qi and other famous generals returned to Hebei safely.

Yuan Shao was defeated and retreated to Hebei. But luckier than in history. He also returned with more than 100,000 soldiers, dozens of generals, and all the strategists, and his foundation was not destroyed. In terms of military strength, it is still better than Cao Cao. Therefore, Cao Cao did not dare to cross the Yellow River to crusade against Yuan Shao.
