The guards everywhere in Jiameng Pass saw thousands of powerful crossbows shooting towards him with wind and thunder. They hurriedly hid behind the solid cover and shouted to their subordinates: "Avoid! Look for cover and avoid it!"

Liu Bei and the generals in Shu had learned about the power of the red-clothed crossbow. They knew that this thing was powerful enough to penetrate stones, but no one expected that the range of the red-clothed crossbow could reach a distance of thousands of steps! This is too scary. Is this still a weapon on earth? This is simply a long-range weapon from hell!

The Shu soldiers on the wall had just been hidden, and the red-clothed crossbow roared and shot down, destroying everything that could be destroyed. Anything that was not solid enough, or that was solid enough but not thick enough, was destroyed by the red-clothed crossbow. The Shu soldiers hiding behind these bunkers were torn apart by the huge penetration power of the red-clothed crossbow in amid the wailing sounds. The red blood splattered out instantly, dyeing the wall of Jiameng Pass red.

The red-clothed crossbow was a sharp weapon developed by Ao Lie based on the manufacturing principles of the Great Qin State of the previous dynasty and the three-bow bed crossbow of the Song Dynasty. It was further improved by Wang Hun and Ma Jun several later joint efforts. For Liu Bei and others, this was an unsolvable problem, because Liu Bei did not have Ao Lie's mind from later generations, nor was he a skillful craftsman like Wang Hun and Ma Jun. Therefore, whenever he faced the bombardment of the red-clothed crossbow, Liu Bei could only be a turtle with his head shrinking, without any resistance at all.

After a round of fierce crossbows fell, after only twenty breaths, another shaking vibration sounded. The Shu soldiers were already very familiar with the sound of the red-clothed crossbows firing. They knew that the second wave of fierce crossbows had been shot out, and hurriedly hid behind a more solid cover. They didn't want to even see the Han army, and just died in a daze under the sharpness of the red-clothed crossbows. Looking at the performance of the Shu soldiers, Liu Bei couldn't help but curse in his heart: How did he study this damn Ao Lie, the red-clothed crossbows? I really don't know what material his brain is made of.

Round after round of red-clothed crossbows kept attacking Jiameng's pass. The suppressed Shu soldiers could not even be able to fight back, not to mention the power of fighting back, even if they could look out of the pass. It was not until more than a dozen rounds of powerful crossbows that the red-clothed crossbows stopped bombarding, allowing these Shu soldiers and generals who had been turtle for a long time to poke their heads out and look out of the pass. Unexpectedly, this look scared them collectively!

It turned out that the Han army advanced five hundred steps forward with the harassment of red-clothed crossbows, especially the front army led by Ao Lie himself, which had approached 300 steps in front of Jiameng Pass. On Ao Lie's side, there were 100 towering arrow towers on both sides. At this moment, these arrow towers were densely filled with Han army archers. The crossbows in their hands had already been on the bow strings, and they could carry out condescending cover attacks on Jiameng Pass at any time. Jiameng Pass is a dangerous pass, but that was just the ground of Jiameng Pass.

The situation is steep. It does not mean how high the walls of Jiameng Pass are. Moreover, in order to attack Yizhou, where there are natural dangers everywhere, Ao Lie specially asked Wang Hun and others to work overtime to raise the arrow tower. Now the arrow towers equipped in the Han army are twelve meters high. It can be said that they are the peak that the craftsmanship of this era can reach. In front of such a height, there are few cities that can match these arrow towers. In the whole world, perhaps only Chang'an, Luoyang and Yanjing can only make a limited city. There is such a height.

After seeing the Han army's arrow tower, the first reaction of the Shu generals was shocked. The second reaction was to quickly yell and issue an order to the soldiers under their respective troops: "Zhang hang wet cowhide, hurry up!" The Shu soldiers acted quickly amid the roars of generals at all levels, and took out cowhide from the materials defending the city, poured clear water on them, hung them everywhere on the walls, and looked down from a high altitude, as if at the critical moment of Jiameng Pass, huge cowhide umbrellas suddenly appeared.

Ao Lie sneered at the corner of his mouth and said to himself: "Do you really think these cowhides can block our army's rain of arrows? What's more, your cowhides are all passive..." He suddenly raised his right hand, and then slashed it heavily, Ao Lie gave the order to shoot.

Xu Chu and Dian Wei, who were following Ao Lie, immediately shouted loudly to both sides: "Boundist, shoot arrows!" The Han army on the arrow towers on both sides immediately raised the bow and arrows, and after aiming slightly, they shot the sharp arrows that had already been on the bowstrings towards the Jiameng Pass. In an instant, the upper, middle and lower Han army of two hundred arrow towers opened fire at the same time. Tens of thousands of sharp arrows flew into the sky, some were diagonally shot, some were ejected, and some were flat shots, with different angles, but the purpose was the same, that is, to effectively kill the Shu soldiers on Jiameng Pass!

When the arrow tower was launching an attack, veteran Huang Zhong ordered the launch of the red-clothed crossbow cannon again. Thousands of powerful crossbows mixed in tens of thousands of sharp arrows, and a real cover attack was launched at Jiameng Pass.

The sharp arrows and powerful crossbows of the Han army had just been fired, and Ao Lie turned to Zhang Liao without waiting for the effect, saying, "Wenyuan, launch an attack on the city!"

Zhang Liao agreed loudly and reached out to his hand to move. The 20,000 Han troops under his subordinates immediately carried the ladder and rushed out behind Zhang Liao. In this battle, Zhang Liao played the role of a vanguard of attacks, and his subordinates had already adapted to such a task and had already prepared various military supplies for siege. When he saw Zhang Liao waved, he rushed out without hesitation.

With Zhang Liao's actions, Taishi Ci brought the 20,000 Han troops from his headquarters to fill the gap left after Zhang Liao's troops rushed out. According to the conventional rules, after Zhang Liao, his troops should prepare. Once Zhang Liao's troops set up the ladder, they would rush over. Following Zhang Liao's troops, they began to forcibly attack the city along the ladder.

At the same time Ao Lie issued an order to attack, after the pass, Ma Chao also led his troops to launch a tough battle. However, it did not launch a strong attack, but let the Hu Ben Lisketeers cover it with crossbows, allowing Wei Yan to lead some of the Hu Ben Lisketeers to attack after the pass. After all, the troops who detoured behind the enemy were only 20,000, and there was a non-combat reduction on the way to march. Even if they were Hu Ben Lisketeers, it would not be possible to forcibly conquer Jiameng Pass with this number of people, attract firepower, distract Liu Bei's attention, and create fighter jets for Ao Lie in front of the pass. This is Ma Chao's strategic goal.

However, it seemed that things were a little beyond Ma Chao's expectations. The cowhides hanging on the wall seemed thick and strong, but they were broken in one bucket. Even the crossbow arrows could not resist. With just two rounds of volleys, the Shu soldiers hiding behind the cowhide were killed by the Hu Ben Lishi in the air.

After discovering this situation, Ma Chao immediately changed his combat policy and shouted loudly at the Huben Lisketeers under his command: "Stop scattering, find the target to carry out accurate strikes, pay attention to saving ammunition!" Although the Xizi crossbow is powerful, it is very small for easy portability. The Xizi crossbow that can be buckled on his arms can only accommodate three crossbow arrows. After two rounds of volleys, the last crossbow arrow was left in the crossbow arrows. However, because this time it was a detour behind enemy lines, each Huben Liskete carried three times the crossbow arrows, which means that they had two spare ammunition to fill the crossbow arrows.

With Ma Chao's order, the Shu soldiers commanded by Fa Zheng immediately suffered greater casualties after the pass. The Hu Ben Lishi was one of the four elite troops of the Northern Han Dynasty. Although they were not all-round troops like the Blood Killing Army, they usually worked hard on hand crossbows, so their shooting level was also first-class. Under the precise strike, crossbow arrows were locked on different targets, causing accurate shooting on Shu soldiers. After more than a dozen breaths, they killed more than 4,000 Shu soldiers, which was better than the combined effect of the two rounds of volleys just now.

This situation was immediately discovered by Fa Zheng at the critical moment. Fa Zheng looked at the cowhide that was blocking the Shu soldiers with doubt. The cowhide was still cowhide, and it was fine to change the thickness. How could it be penetrated so easily? Could it be that the Han army's crossbow was too powerful, not only could it reach the range of bows and arrows, but its attack power was also sharper than ordinary crossbows?

"Press the two cowhides together, I want to see how powerful their crossbows are!" After Fa Zheng did not find the problem, he could only attribute the reason why the cowhides he hung was easily penetrated by the Han army's crossbows to the reason why the power of the crossbows was too great, and thus issued such an order.

When the Shu soldiers were adjusting according to Fazheng's order, Fazheng waved to call General Zhang Yi and asked in a low voice: "Is there any problem with these cowhides?" Fazheng knew that he was a civil servant and was not very familiar with military resources like cowhides. Zhang Yi and Zhang Yi were both generals from the army and they knew all the military equipment, so Fazheng had this question.

Zhang Yi said with confusion: "There were a few cowhides that were hung by someone just now. Judging from the thickness and weight, there was no problem. I just realized that the flexibility of these cowhides seems to be slightly worse than usual, but this does not mean that there is a problem with cowhides. After storage for a long time, it is normal for cowhides to become hard, and this will not affect the toughness of cowhides. Logically speaking, it should not be impossible to stop the penetration of the crossbow, even if the Han army, uh, Yan army's crossbows are very powerful."

"What the hell is going on? Why can't these cowhides stop the Han army's crossbow arrows?" Fa Zheng lowered his head and thought with a look of confusion...

The things that made Fazheng confused were also troubled by Liu Bei on the main battlefield in front of the pass. The Shu generals in front of the pass were full of confidence that the cowhide they hung could block most of the Han army's bows and arrows, but what was surprising was that these cowhides were like paper and became fragile. Under the stings of tens of thousands of sharp arrows in the Han army, none of them played the role they deserved, and were pierced by sharp arrows without exception.
