In order to rebuild Jiexiu's city wall, Cao Liang specially built several large brick kilns around Jiexiu to fire green bricks. Jinzhong area is rich in clay for burning bricks. In later generations, this place was also a relatively famous brick production site, so it was not too much effort to fire green bricks.

But rebuilding a city is not easy. It took nearly two years for the Bingzhou army to officially complete the construction. Jiexiu City, which cost a huge price, is naturally second to none in terms of defense. Sima Jun wanted to throw a few stones to break Jiexiu's walls, which was just a delusion.

Of course, the target Sima Jun wanted to attack was naturally not the city wall. Although smashing the city wall is also a good choice, it takes time. As long as you take turns to attack, you can destroy the city wall.

Before this, what they wanted to do the most was to destroy the most threatening things, such as the catapult cart and the arrow tower of the Bingzhou Army. Unfortunately, they lacked accuracy, and most of the stone bombs they threw were outside and inside the city. There were very few people who actually threw them on the city, let alone destroying the catapult cart and arrow tower, and they didn't even get any hairs on them.

Sima Jun's stone bullets were not all carved into spherical shapes like the Bingzhou Jun. They just simply processed the stones they were preparing to use. The stones basically showed irregular shapes, and the weight was naturally difficult to ensure consistency.

In addition, Sima Jun’s catapults are all pull-type catapults. The biggest problem with the catapults relying on manpower is that they cannot fully control their strength. Even if the experienced pitcher is unable to throw the stone bombs to the same place twice.

So although Sima Jun did aim at the arrow tower on the city in the first round, none of the stones could hit the target.

Before they could load the second round, the counterattack of the Bingzhou Army's catapult had already arrived. In other words, the Sima Army's stone bullet had just fallen to Jiexiu's city, and the Bingzhou Army's catapult had already taken action.

Although the attack was also rushed, the Bingzhou Army's hit rate was not as low as that. At least three or four of dozens of stone bombs hit the target. These stone casters were instantly destroyed, and two bed crossbows were also included. As for casualties, they can be ignored for the time being.

Under the wide hat brim, Sima Yi's face became solemn. As soon as an expert took action, he knew whether there was any. It was just the first round of competition. Moreover, Sima's catapult cart was several times that of the Bingzhou army, but the effect of the battle was very different. Sima Yi finally understood why Sima's army sent more than 100 catapult cars yesterday but the entire army was destroyed. It seems that in terms of hit rate, the two sides were not on the same level.

Chen Qian and Sima Shi's expressions also changed drastically. They originally thought that using the cigarette barrier today would give them the opportunity to take the lead, but now it seems that taking the lead is meaningless. Under the precise attack of the Bingzhou Army, they could not escape the destruction of the entire army.

But it is too late to retreat now, so Chen Qian could only bite the bullet and fight against the Bingzhou army. Fortunately, the Sima army suffered a small loss in the first round of battle. He still had the power to counterattack. Chen Qian ordered the opponent's catapult car to attack with all his might.

At the same time, the crossbow also shot with all its strength, nailing the pedal arrow to the city wall.

After several rounds of adjustments, Sima Jun's hitchhiking car finally increased a little, so he would not throw the stone bullets to the moat, and even the city walls could not be thrown up. Moreover, they finally destroyed the first arrow tower. Whether it was a blind cat or not, it was finally the first substantial result achieved by Sima Jun's thrown car.

A burst of cheers sounded on the Sima Army's position, and Chen Qian finally breathed a sigh of relief. Today's performance of the catapult was finally stronger than yesterday. In the battle yesterday, the catapult was destroyed without even throwing a stone bullet. This was a great shame.

Today, Sima Jun's stone bullet finally hit the city wall and threw it on the top of the city, which can also destroy an important target. As for the opponent's catapult, it has always been hidden behind the city wall, and it is too difficult to hit, and it cannot be destroyed even if you want to destroy it. If some catapult cars can be destroyed, it is the real victory.

Chen Qian took a peek at Sima Yi. Sima Yi's face did not change because of destroying an arrow tower, but instead became deeper. In fact, compared to Sima Jun's miserable situation, such a little victory is indeed not worthy of complacency.

After several rounds of stone bombs were launched continuously, the hit rate of the Bingzhou Army's catapult car increased. Although it was not as good as yesterday, two or three out of ten were not much the same. Sima Army's catapult car was continuously destroyed, and the battlefield was in chaos.

You should know that the Bingzhou Army's catapults were not gathered in the south of the city, but were distributed on all four walls. The south wall only accounts for one-quarter of them, and the number cannot be compared with the Bingzhou Army. However, because the hit is much higher than that of the Sima Army, the Bingzhou Army has an overwhelming advantage.

Sima Jun's numerical advantage was naturally quickly lost after the catapult was continuously destroyed. No wonder Sima Yi's face was not very good-looking, suppressing his opponent in terms of quantity. Under the condition of taking the initiative, Sima Jun's catapult was so miserable. Such a battle was really impossible to fight again.

When Sima Shi saw Sima Yi's eyes falling on the stone bullet that fell not far away in front, he immediately sent someone to carry the stone bullet back and let Sima Yi take a closer look.

After a close look, Sima Yi fell into deep thought. These stone bullets were completely different from those used by Sima Jun. Could it be that the hit rate can be improved just by carving the stone bullets into ball shapes?

Is the truth really that simple?

Sima Yi shook his head gently. He could not make an assertion before he saw the true face of the Bingzhou Army's catapult, but the Sima Army was completely defeated by the contest between the catapults of the two sides. No matter what method was used, he could not recover this defeat.

The attack of the crossbow did not seem to have any good effect. These crossbow arrows were originally intended to be shot on the city wall, but the solidity of the brick wall was not comparable to that of the rammed earth city wall. No matter how sharp the crossbow arrows were, they could only penetrate the surface of the city wall. They could not bury the tip of the arrow deep into the city wall. Some crossbow arrows could not be shot in at all. After hitting the city wall, some bricks would collapse and the arrows fell aside.

Such a pedaling arrow will not play a role at all. If Sima Jun wants to build an alternative ladder, it may be difficult for him to achieve this goal.
