When dealing with Sima Jun's catapult car, the Bingzhou Army used counterweight catapult car. The stone bullets used in this kind of catapult car are relatively large, each of which is like a human head. And only the counterweight catapult car has such a high hit rate. The gunner skillfully controls the catapult car. Even if the first stone bullet does not hit the target, after a simple adjustment, the second stone bullet is shot perfectly.

However, when dealing with dense crowds, the efficiency of equipped catapults is weaker than that of serial catapults.

The serial stone launcher is Ma Jun's hard work. Its biggest improvement is that a huge rotor is added behind the catapult car. All of these rock bullets are suspended on the rotor, which can speed up the speed of adding bullets and improve the attack efficiency of the catapult car.

Although the stone bullets of the serial stone caster are one size smaller than those of the counterweight caster, the range is closer, and the hit accuracy is incomparable, the serial stone caster has its biggest advantage, that is, the speed of fire is fast. When the counterweight caster fires a stone caster, the serial stone caster can throw three or four stone bullets.

This high-frequency attack weapon is naturally the most effective weapon to deal with dense crowds. Dozens of serial stone-striking cars attacked at the same time, and the stone bullet hit Sima Jun's head like hail.

Of course, this is just a metaphor. These stone bullets are much more powerful than hail. No matter how big the hail is, they will be smashed to the head at most. When these stone bullets fall on top of the head, their heads will almost be smashed.

At the critical moment, these rock bullets were too dense, which made Sima's army unable to defend themselves. Instead, they were willing to speed up and escape from the coverage of these rock bullets, so that they could avoid the attack of the rock bullets.

However, this was just Sima Bing's wishful thinking. After crossing the stone bomb area, they immediately entered the arrow area. Although the damage level of the bow and arrow cannot be compared with the catapult cart, the density of the bow and arrow made the catapult cart look close to it.

As soon as the Sima army entered the range of the archers, they could immediately smell the breath of death covered, and the dense rain of arrows poured out immediately, blocking the Sima army's way forward.

The arrow rains of Bingzhou Army are so dense that it is entirely due to the construction of many new arrow towers on the city wall. The arrow tower is a wooden structure with three layers above and below. One is set up at a fixed distance between the four corners of the city and the city wall. This three-layer structure can accommodate more archers. The arrow tower itself has a protective baffle that can protect the archers staying on it from being damaged by the opponent's bows and arrows. Their attacks are completely reckless.

In fact, the biggest enemy of this wooden arrow tower is the catapult cart. A huge rock flies over and can easily destroy the arrow tower. Therefore, the Bingzhou Army placed catapult carts on the city walls more to protect the safety of these arrow towers. Before Sima's army's catapult cart attacks, they destroyed these possible threats.

Although Sima Jun's catapult was extremely low in accuracy, as long as the catapult fired too many stone bombs, the blind cat could even encounter a dead mouse, so removing these threats is the best way.

Of course, Sima Jun had never seen the power of the arrow tower before, so he naturally didn't know what these arrow towers were used for. He just saw from a distance that there were some tower-shaped wooden structures on Jiexiu's city walls.

Generally speaking, building some hanging buckets or wooden towers in the city or on the walls can play a role in looking out. But in theory, you only need to build one or two buildings. There is no need to build so many?

When the Sima army entered the range of the Bingzhou army's bows and arrows, they suddenly discovered that these wooden towers actually contained a lot of archers. The three-layer structure was equivalent to the Bingzhou army having three times the firepower and could fire more arrows at the same time.

As soon as Sima Jun launched an attack, he clearly felt the pressure brought by the arrow tower, and the resistance to the attack increased significantly.

In fact, the Sima army had not yet attacked the city or launched an attack on the city. Only then would they realize the real terrifying aspects of the Arrow Tower.

These arrow towers are not parallel to the city wall. They are built on the city wall, but they are obviously protruding from the city wall. It is precisely because of the extra distance that the arrow tower's attack range becomes larger.

The archers on the city wall have only one direction in front, and the arrow tower can not only attack the front, but also attack the left and right sides and the bottom, carrying out a full-dimensional three-dimensional attack.

This structure is similar to the horse face at the city gate. The horse face increases the defense ability on the side of the city, but with just four horse faces, it is still beyond the reach of such a wide distance.

The arrow tower has solved this problem to a large extent. Since the arrow tower is set up more and can be taken into account both left and right, these arrow towers have greatly strengthened the defense capabilities on the side of the city wall.

To attack ordinary cities, the attacking party only needs to pay attention to the enemy on the front. After having the arrow tower, their flanks will be exposed to the coverage of the defenders' bows and arrows, and they will also suffer strikes from three directions, making the already difficult siege operation even more difficult.

So such an arrow tower is the real nightmare for the siege.

At this time, Sima Jun did not realize how terrible the arrow tower was. He just felt that the arrow rain they had suffered was much denser than usual. Fortunately, most of the siege troops were equipped with rectangular shields with relatively large coverage, so that they could withstand the attacks of arrows when they advanced.

But these arrows are always pervasive. Even if the Sima Army's protection is tight, it will always leave a certain gap. These gaps will often become fatal places, and they will move forward all the way forward, and people will be constantly caught and fallen to the ground, with countless casualties.

The most casualties were the infantry carrying the ladder. Because they had to hold the ladder with one hand and had to hold the shield, they would always leave a larger gap. These dense rain-like arrows would easily shoot and kill these infantry through these gaps.

When the Sima army attacked, it was equipped with a large number of archers to cover. Although their counterattack played a certain role in suppressing the Bingzhou Army on the city wall, the suppression effect was much worse for the archers on the archer tower. Because the baffle was installed on the archer tower, these archers could basically ignore the counterattack.

Sima Jun walked around and advanced very slowly. They had already worked very hard just by the distance from this arrow, but when they advanced to the city, there was a greater test in front of them, that was the moat under Jiexiu City.
