The trebuchet is far from being able to accurately control the landing like the cannons of later generations, two hundred and fifty steps away, the earth-shaking thunder should accurately fall on the two-zhang wide city head, it is by no means an easy task, only three percent of the hundred earth-shaking thunder fall on the city head, and the other sky-shaking thunder either smashed on the city wall, or crossed the city head and fell into the city.

And the earth-shaking thunder that fell on the head of the city did not explode in time, there was no technology to control the explosion point, and it was completely determined by the experience of the gunpowder craftsman, the earth-shaking thunder made by the Song army, the fire rope used was the standard three feet, of which about one foot was inside the thunder, and the other two feet were outside, on the eve of deciding a certain battle, the gunpowder craftsman would make a launch scale mark on the fire rope, and it could be launched when it was burned to this scale, which basically guaranteed that it would not explode in advance, or delay the explosion for too long.

But this trick is the patent of the Song army, at present, there are only five gunpowder craftsmen in the Song army who can make accurate judgments, these five gunpowder craftsmen are currently in the Jingzhao army, and the Jin soldiers are completely determined by the launcher himself, without precise control, the result can be imagined, all the thirty earth-shaking thunderbolts that hit the head of the city did not fall to the ground and exploded, but rushed directly down the city, fell into the deep pit in the city, and exploded in the deep pit.

An explosion broke out outside the city and inside the city at the same time, such as thunder in the continuous explosion, thick smoke filled, not waiting for the smoke to dissipate, the second round of earth-shaking thunder was launched again, the Song army at the head of the city tightly covered their ears, lying under the battlements, waiting for the end of the golden soldiers' might.

This time, the Jin soldiers brought 800 captured Song Army Earthquake Thunder, plus the original more than 200 pieces, the Heaven Shaking Thunder in the hands of the Jin soldiers exceeded 1,000, but they could not withstand the squandering of the Jin soldiers, one round of launches, 200 were consumed, and 1,000 Heaven Shaking Thunder was only enough to launch five rounds.

Wan Yanchang also understood this, so after two rounds of explosions, he ordered two thousand soldiers to push the siege vehicle to attack the city gate, preparing to take advantage of the opportunity to suppress the Song army and use the battering ram to break open the city gate.

A siege vehicle was pushed and dragged by the soldiers and rumbled towards the city gate, the siege vehicle had eight wheels, four on each side, there was a roof above, a huge battering ram was hung on the thick wooden frame with an iron chain, the mallet body was three zhang long, it was made of a thousand-year-old giant wood, the mallet head was loaded with pig iron, the impact force was particularly strong, a hit on the door, there was a force of ten thousand catties, and no matter how strong the city gate would be knocked open.

At this time, the trebuchet launched a third attack on the head of the city, and the siege vehicle also advanced rapidly, only thirty steps away from the city gate, the drawbridge in front of it had been blown up, and the moat was covered with thick ice, and the siege vehicle accelerated and drove towards the ice of the moat.

At this moment, the Song soldiers at the head of the city threw a few torches in front of the city gate, and the fire burned within fifty steps in front of the moat, the flames rose into the air, and the fire burned rapidly, which was the Song army in order to prevent the Jin soldiers from taking the opportunity to hit the city gate with a battering ram, and buried the fire oil in advance, and the siege vehicle and the surrounding Jin soldiers immediately fell into the sea of fire.

'Boom! Bang! The two giant earth-shaking thunderbolts buried in the ground exploded, and the huge shock wave blew the siege vehicle into two pieces and flew several feet away, and the surrounding 2,000 soldiers died in the violent explosion of the giant sky-shaking thunder before they could break free from the flames.

And at this time, the Jin soldiers launched the fourth round of earth-shattering thunder attacks, and after a series of explosions in the city, the battlefield was completely quiet, and only thick gunpowder smoke drifted over the city.

The smoke had cleared, and a large pit appeared about seventy steps in front of the city gate, and on both sides of the pit lay the remains of the shattered corpses, the blood stained the mud, and the base of the huge siege vehicle was blown in two, facing the sky on its back, and the battering ram was also thrown aside, crushing dozens of soldiers into meatloaf.

Although there were four rounds of sky-shaking thunder bombardment, Taiyuan City was still standing, 800 sky-shaking thunderbolts were thrown at the city, but less than ten exploded on the city, and dozens of Song soldiers were injured.

But the Jin soldiers also had a gain, that is, almost half of the trebuchets on the city head were damaged and needed to be repaired before they could be used, the two towers were blown to pieces and disappeared from the city towers, and the city was even more scarred within a hundred steps of the city wall, and the earth was blown up everywhere, and the deep pit was covered with shell iron sheets.

Jin Bing didn't launch the fifth round of Heaven-Shaking Thunder Projection, he only had less than three hundred Sky-Shaking Thunderbolts left, and he didn't dare to waste them any more.

At this time, the golden soldiers were replaced by boulder attacks, and the boulders were loaded into the trebuchet, and the black pressed stones were smashed towards the city.......

Wan Yan Chang and Wan Yan Zongbi invested 10,000 troops almost at the same time, launched an attack on the city, overwhelming the soldiers rushed to the city wall, Wan Yan Chang invested 10,000 Han soldiers mobilized from the south of Hedong Road, and at the same time ordered 2,000 Jurchen cavalry as prison soldiers.

Wanyan Zongbi invested 10,000 Xi infantry, Xi people are fierce and brave, and their combat effectiveness is very strong.

Without the threat of earth-shattering thunder, the Song army on the city also began to be active, a large number of Song soldiers began to return from the west and south of the city, and the artillery and bed crossbows were also pushed back to the city, Li Yanqing ordered the use of trebuchets to be temporarily stopped, and he did not allow the soldiers to take risks before the inspection and repair were completed.

The first to fire is the Song army's bed crossbow, a four-foot-long crossbow shot strongly at the enemy's trebuchet, the big crossbow is wrapped with a powder tube, constantly exploding around the trebuchet, although this powder tube is only equivalent to a cannon battle, but it is mixed with a lot of sharp iron pieces, the belt or throwing rod of the trebuchet is hit by the iron sheet, and it is broken, which can easily lead to the destruction of the trebuchet.

At the head of Dongcheng, two hundred crossbow arrows shot out from the bed crossbow, crackling at a hundred huge trebuchets......

Li Yanqing was standing on the north city at this time, his eyes staring coldly at the overwhelming 10,000 gold soldiers, he turned around and shouted: "Archers prepare!" ”

The five thousand archers half-squatted on the city wall, pulled out the big bow, and the cold tip of the arrow was slightly inclined upwards at a thirty-degree angle, Li Yanqing gave an order, "Shoot!" ”

The sound of bangzi sounded, and five thousand arrows rose into the air, drawing a beautiful parabola, dense like locusts shooting at the golden soldiers below, the golden soldiers raised their shields to meet each other, but the penetrating arrows also pierced the shields of countless soldiers, and the soldiers in front screamed and fell, but the soldiers behind did not stop, and continued to rush forward.

"Ready—put!"

The second round of arrows rained down, and the soldiers once again flipped on their backs.

At the same time, the situation also appeared in Dongcheng, but the reaction of the soldiers was very different, the 10,000 Han troops were reluctant to go to the battlefield, the morale was very low, they were poorly equipped, most of the soldiers were not equipped with shields, when the arrows at the head of the city fell like hail raindrops, rows of soldiers wailed and fell to the ground, the soldiers behind were frightened and trembled, their legs trembled, and many soldiers turned around and fled.

Wan Yan Chang had long known that the morale of the Han soldiers was low, but he needed this army as the vanguard to attract the firepower of the Song army to cover his real actions, he was more experienced than Wan Yan Zongbi, and knew the difficulty of attacking the city, and only in the fierce battle was to take the opportunity to blow up the city gate with earth-shattering thunder was his goal.

After he killed this army, he sent two thousand Jurchen cavalry to supervise the battle behind, at this time, the first batch of soldiers turned around and fled back, they encountered ten times more fierce than the rain of arrows, two thousand war cavalry shouted and cursed, the sword in his hand did not hesitate to cut at the fleeing soldiers, killing hundreds of people in a moment, the Han soldiers were killed in fear, so they had to turn around and continue to rush towards the city wall.

At the head of the city, Wang Gui also scolded in a low voice, these soldiers are willing to be alien eagle dogs, and they deserve to die, at this time, the golden soldiers besieging the city have been killed under the city, and the trebuchets in the distance have also stopped attacking, Wang Gui immediately shouted: "Fire cannon shooting!" ”

The yellow flag waved, the soldiers lit the fire rope, when it burned to the red scale, the two hundred cannons on the head of the city were launched almost at the same time, and the two hundred earth-shaking thunderbolts were shot to the city, the earth-shaking thunder did not land and exploded overhead, these Han soldiers did not have the training to prevent the earth-shaking thunder, after the explosion of the earth-shaking thunder, the dense shrapnel burst out in all directions, and there were countless quenched iron pieces inside, and suddenly the screams were continuous, and almost none of the soldiers within fifty steps to one hundred steps under the city wall were spared, all of them were more or less hit by the iron sheets, and the casualties exceeded 2,000 people.

Wan Yanchang was furious, and threw in another 5,000 Han soldiers, shouting: "Beat the drum to urge the battle!" ”

'Boom! Boom! Boom! ’

The drums beat loudly, and the Han soldiers on the battlefield were forced to go forward and kill the city one after another, and they were greeted by ruthless arrows and earth-shattering killing.......

In the chaos, there were thirty Khitan soldiers with earth-shaking thunder were quickly running towards the city gate, but they were immediately discovered by the mine-watching soldiers at the head of the city, according to Wang Gui's suggestion, Li Yanqing set up a thousand mine-watching soldiers in the army, their task was not to shoot arrows to hit the enemy, nor to stand at the head of the city and fight with the enemy, but to observe and prevent the enemy from bombing the city with earth-shaking thunder in the chaos.

Not only there are hundreds of thunder watchers in the east city, but also in the north city, the city gate is the key target of their prevention, and the thirty enemy soldiers under the city are abnormally rushing towards the city gate, holding the black earth-shaking thunder like a winter melon in their arms, of course, they can't escape the eyes of those who have a heart.

Without waiting for these thirty people to approach the city gate, hundreds of soldiers raised their crossbow arrows and shot at them, these thirty enemy soldiers were caught off guard, and most of them were shot down by random arrows, and several earth-shaking thunders also came out of their hands and rolled down on the ice of the moat.

Just a few people rushed to the city, hundreds of buckets of water were splashed on the head of the city, several soldiers were suddenly poured into soup chickens, the earth-shaking thunder in their hands was also soaked, the fire rope could not be ignited again, several soldiers desperately threw away the earth-shaking thunder, turned around and fled, but ran out of a few steps, arrows from behind intensively, five soldiers screamed and were shot down, and died instantly.......

The cannon shot two rounds of earth-shattering thunder in a row to the city, exploding continuously in the crowd, and there were arrows shot by the storm overhead, the battlefield outside the eastern city has become a slaughterhouse, a meat grinder, the Han soldiers were forcibly driven to charge, and they died under the city in batches, and the price of their death was to complete the Yanchang expectation, and there was no possibility of a successful sneak attack.
