In the early morning, in Youzhou City, Yelu Hu was urging his horse to run towards the city wall. Just now he heard a news that the Song army erected an extremely huge catapult in the east of the city, which surprised him secretly.

Yelu Hu ran up to the city and saw a giant catapult hundreds of steps away at a glance. It was even larger than the giant catapult, far exceeding the city wall. The casting rod was ten feet long, which was twice as long as the heavy catapult at the city. There were six huge wheels below, each wooden wheel was taller than a man.

"Master, this should have been shipped last night. Many brothers heard something outside."

Yelu Huji also heard a strange sound, a rumbling sound, as if it was a sound coming from a black box below. Yelu Huji frowned. What was the big black box?

Yelu Huji stared for a moment and asked again, "Is this the only one?"

"There is only this one at the moment!"

Yelu Huji nodded, "It's probably they're testing it."

Before he could finish speaking, he heard a loud "bang!" and a big rock flew towards the city wall. Everyone was so scared that they shouted, and they squatted down to avoid it.

The big stone crossed the city wall and hit the city. Soon, the super trencher began to slowly retreat for more than ten steps. Soon, another huge rock hit. The huge rock hit the city, bounced up at the top of the city, and just hit the leg pillar of a heavy trencher at the top of the city. The leg pillar broke, and the catapult fell down with a bang, pressing two soldiers who could not dodge below.

Yelu Huji cursed fiercely, saying that it would not be possible to be beaten like this. He must have weapons to deal with the enemy's super trencher.

A soldier suggested: "Master, the range of the bed crossbow can exceed the range of the deal!"

A word reminded Yelu Huji, and he nodded, "So quickly order the military craftsman to come and see me!"

Yelu Huji realized the danger and immediately increased the creation. There were more than 200 crossbows in the warehouse, but he ordered them all to be carried to the top of the city.

"shooting!"

At the top of the city, two hundred crossbows were fired at the same time, and dense arrows shot towards the super catapult five hundred steps away.

The crossbow's arrow is about three feet long and thicker than the thumb. It can penetrate gold and crack stones within 600 steps, and it has extremely strong lethality.

Song Jun's super catapult was also protected. He placed a two-meter-high wooden board in front, supported by triangular wooden pillars. However, Song Jun did not expect that the other party's crossbow was so powerful that it actually shot through the wooden board, and dozens of crossbow arrows were nailed to the high wooden frame.

The catapult is made of giant wood. The wooden stake itself is not afraid of arrows, but the bracket connection and throwing rod at the top are relatively sensitive. It is the key part of the catapult. Because the position is too high, it cannot be defended. The Song army's super catapult cannot hold back the powerful crossbow arrow on the head of the city, and has to retreat slowly and retreat beyond the range of the crossbow. The city suddenly cheered.

In the afternoon, Fanning and Cao Shi led thousands of troops to outside the East City of Youzhou. At this time, the super catapult had retreated to the range of the crossbow. Fanning turned over and dismounted and asked, "Is there any loss?"

The military weapon supervisor in charge of the test saluted: "I reported to you that the thief was shot thirty-eight arrows, but the key points were not shot, and there were basically no losses, but two craftsmen were seriously injured."

"Can you send it to the treatment?"

"Have been sent back to Lu County for treatment."

Fanning nodded, walked under the catapult, and asked again: "How is the test effective?"

"The test effect is very successful, including the tension of the steam engine, and we can accurately hit the head of the city with a hundred kilograms of boulders."

"Then is there any way to defend against the enemy's crossbow?"

The military weapon supervisor hesitated and said: "I initially consider placing a copper shield in front of the three connection points, but I am worried that the slightly thin wooden pillar will be shot off, or that the burning gunpowder cartridge will still have an impact on the catapult."

At this time, Cao Shi said to Fan Ning: "Don't think about any defensive weapons. In fact, the best defense method is to attack. Use hundreds of iron fire thunder to bomb the city, and all the crossbows will be blown into powder!"

Fanning smiled, "This is a bit reasonable, but before twenty super treble aircraft show their power, there must be defensive measures to adapt to."

He said to the military weapon supervisor again: "I don't care whether you wrap iron or cowhide, you should consider it yourself, but I don't want any catapult to fall under the enemy's crossbow arrows."

The war is getting closer and closer. Half a month later, all twenty super trenchers were assembled.

On that morning, 200,000 troops arrived at Youzhou City and built a wall-shaped camp in the wilderness three miles away from Youzhou City. Tens of thousands of large tents appeared quickly in the wilderness like mushrooms after the rain. The camp of the Song army was only east and south, with a "l" layout, with a total length of about ten miles. From the top of the city, dense tents were paved on the ground, which was particularly spectacular.

At night, dozens of strong cows came slowly with huge catapults. In order to transport these twenty catapults, the Song army went all out. They first built five bridges across the Lushui River, and then organized 50,000 militias to broaden the official road from Lu County to Youzhou City, and consolidated it to an extremely flattening manner, so that the huge catapult could move smoothly without losing its center of gravity and turning over.

The seats of the twenty catapults have been determined, all located in the east of the city. This is also the strategy formulated by Fanning and the two deputy commanders, concentrating firepower to attack the east of the city.

Twenty black shadows, like hills, appeared outside the city, immediately alarmed the defenders on the top of the city, and the defenders quickly reported to Yelu Hu.

Not long after, Yelu Hujiu rushed to the top of the city. He stared for a moment and asked, "Is there a catapult in the south of the city?"

"No! At present, only enemy catapults were found in the east of the city."

Yelu Huji immediately ordered: "Change all the crossbows in various places to the east of the city!"

At present, the Liao army has built a total of 500 bed crossbows, distributed and deployed on four cities. However, judging from the situation in front of them, it is estimated that the Song army will concentrate its forces to attack the east of the city. Yelu Hu made a quick decision and made a decision.

The Liao army on the top of the city was very fast. In just a moment, it moved all five hundred crossbows to Dongchengtou. At this time, twenty super trenchers had been positioned, and the low roar of the steam engine began to sound.

"shooting!"

Even at night, Yelu Huji still issued an order to launch, and five hundred crossbows were fired at the same time, and dense crossbow arrows were aimed at the dark mountains and allusions.

After all, it was night, and most of the crossbow arrows shot in the air, but it still had an impact on the installation and debugging of the Song army.

Several craftsmen were shot by crossbow arrows and fell to the ground screaming. Other craftsmen ran under the baffle to avoid crossbow arrows. A super trencher was shot into the belt. The belt was broken, and the trencher suddenly lost balance and made a terrible sound, as if it was about to collapse at any time.

The soldiers were so shocked that they shouted to escape, but a belt broke would not have collapsed the entire catapult, and the catapult finally stabilized.

The news of the Liao army launching an offensive at night reached Fan Ning. He was furious and immediately ordered: "Boat with iron fire and thunder!"

The Song army's super trencher did not plan to siege the city at night, but only debugged at night and launched an attack after dawn.

However, the Liao army's bed crossbow night shooting forced the Song army to change the plan and directly change the debugging to counterattack.

Just as the Liao army shot out the third round of crossbow arrows, the Song army's super catapult also began to counterattack, with a series of collisions.

Nineteen large iron fire thunders weighing hundreds of pounds rose into the air and flew towards the top of Youzhou city.

There are three types of iron fire thunders of the Song army. One is the ordinary iron fire thunder, weighing 50 kilograms, which is mainly used for crossbow fire or water battles; the second is the heavy iron fire thunder weighing 100 kilograms. This kind of iron fire thunder is the most widely used, and it is used for siege and defending cities and positional battles, and it is extremely powerful; the third is the super heavy iron fire thunder of 150 kilograms, also known as city explosion iron fire thunder. This kind of iron fire thunder is specially used for blasting cities. Because it is too heavy, it is not used much in other aspects.

The Liao army on the top of the city was preparing for the fourth launch when suddenly a soldier pointed to the air and shouted, and saw sparks appearing in the air. Before the soldiers could react, a hundred kilograms of iron and thunder hit the top of the city, and then exploded violently.

Twelve of the nineteen iron fire thunders hit the city head accurately, three passed the city head, and four hit the city wall.

Iron pieces and flames burst out, and the air waves swept across the city. Hundreds of poisonous iron nails in the iron fire thunder shot around like a storm. The catapult collapsed, the crossbow was broken, and the soldiers on the city were hit by iron nails, screaming.

After the explosion, the city wall became a mess, hundreds of crossbows were destroyed, fifteen catapults collapsed, and nearly a thousand soldiers on the city wall were injured and killed.
