Sima Yi's method was very simple, that is, to use smoke to hide the deployment and arrangement of Sima Jun, and the weather conditions at this time provided great convenience to Sima Yi's plan, which could just form a smoke barrier to obstruct the sight of the Bingzhou army, but it did not affect the deployment of Sima Jun's catapult at all.

Although Sima Jun's catapult was wiped out yesterday, only a small number of casualties were among the dragging hands who operated the catapult, and most of them were safe and sound, so after the new catapult was in place, these dragging hands could return to work.

Although the deployment of the catapult is a time-consuming and laborious task, with the smoke barrier in front of it, Sima Jun does not have to worry about the attack of the state army, and they can calmly complete the deployment of the catapult.

Not only catapults, but also the newly added bed crossbows were deployed on the forward positions at the same time, but they were not aimed at the defenders, but at the walls of Jiexiu.

These bed crossbows, the crossbow arrows used are also called pedal arrows, which are specially shot to the city wall, and there are special rules when shooting, forming steps like steps, so that the soldiers besieging the city do not have to use the ladder, and they can climb the city wall by stepping on the arrows one by one.

This way of using the treadmill arrow to attack the city is ancient, although it is not as easy to use as the ladder, but it is not easy to be destroyed, this is probably also the solution that Sima Yi felt that the ladder of the Sima army was damaged too much on the first day of the first battle, and he deliberately mobilized a large number of bed crossbows to support.

Chen Qian and Sima Shi looked at each other for a moment, and had to say that Sima Yi's method was simple and effective, if they had adopted it earlier, then the catapult would have been a failure like that yesterday, at least it would not have been beaten by others without even throwing a stone.

In fact, this is a matter of experience, they don't know the role of smoke, but they don't think of applying it on this occasion, and Sima Yi is full of experience, and he has a lot of experience in facing the enemy, it is estimated that when he saw the battle report yesterday, he had already thought of using smoke as a cover, so he just set up the formation today, and he instructed Sima Shi to arrange the setting fire and smoke, and then he could calmly deploy the catapult.

This ginger is still old and spicy, and Chen Qian and Sima Shi are secretly admiring.

"General Yang, what kind of reputation is this Sima Jun?" Seeing that the smoke was getting thicker and thicker, some of the conditions in Sima Jun's array could be vaguely seen before, but later, it was completely invisible, and there was nothing in front of him except a cloud of fog, as if tens of thousands of Sima Jun were invisible at the moment. A school captain couldn't hold back and couldn't help but ask Yanghu.

Yang Hu had already calculated the real purpose of Sima Jun's release of smoke, because the smoke would not provide much help for Sima Jun's attack, so there was only one possibility, and that was to provide cover for Sima Jun's deployment of catapults.

However, even if he knew that Sima Jun was deploying the catapult, Yanghu couldn't do anything at the moment, after all, even if the catapult could shoot accurately. It is also impossible to hit targets behind the smoke, so only when they show their true faces, can the catapults of the state army carry out precision strikes.

But it would be almost impossible to achieve a crushing victory like yesterday's, after all, as soon as the smoke of Sima's army had withdrawn, those catapults would probably start attacking.

Behind the smoke, it is still a mystery how many catapults Sima Jun deployed, so in order to deal with a possible attack by Sima Jun, Yanghu not only ordered the Catapult troops to be in a state of readiness, but also ordered the defenders to hang wet cowhides on the city walls.

Wet cowhide has strong toughness and elasticity, which can resist the attack of stone bullets, and a large number of wet cowhide on the city wall, especially around the arrow tower, can effectively alleviate the damage caused by enemy stone bullets.

There is no doubt that the arrow towers and catapults will be the first targets of the Sima army, but the catapults do not matter, they are hidden behind the city walls, and it is difficult for the Sima army to see them from the city below, and can only be roughly judged by the direction in which the stone projectiles are thrown.

But the arrow towers are different, they are suspended outside the city wall, it is difficult to attract attention, and the upper and lower three floors, at least thirty or forty people, the volume is huge, even if Sima Jun's catapult is not accurate, throwing it in this direction, it is very likely to hit these arrow towers.

These arrow towers are the most critical existence in the city defense system of Jiexiu City, it is precisely because of these arrow towers that the city defense of Jiexiu can be upgraded several grades, if it is defeated by Sima Jun, it may make the defense system of the city wall much weaker, so no matter what the circumstances, Yanghu must try to ensure the safety of these arrow towers as much as possible.

Although there are a lot of wet cowhides hanging around the tower, this is a palliative solution after all, and if the enemy catapults are constantly attacked, no amount of wet cowhide can guarantee that the tower will not be destroyed.

Therefore, the most important thing is the contest between catapults, and only by defeating the other party's catapults can the threat be truly lifted.

Although the battlefield is now full of smoke, Yanghu knows very well that this is temporary, after the deployment of Sima Jun's catapult is completed, this smoke barrier will eventually be removed, otherwise there will be fog and chaos ahead, and Sima Jun's catapult will not be able to find its target.

Sure enough, after about two moments, Sima Jun's soldiers began to pour water on the fires, extinguishing the fires, and as soon as the fire was extinguished, the smoke naturally dispersed.

Sima Jun's catapult was completely prepared before sending people to extinguish the fire, when Jiexiu's city just appeared in Sima Jun's field of vision, Sima Jun's catapult took the lead in attacking, hundreds of stone bullets flew out of Sima Jun's position under the loud shouting of the hand, and flew towards the city head of Jiexiu, dense, like a stone rain.

However, there may be a big problem with the accuracy of the first shot, the smoke barrier has just been removed, and these catapults have not had time to adjust, so they have thrown the prepared stone projectiles.

The force was lighter, and even the city wall didn't shoot up, but fell down on the edge of the moat, and the force was too strong, and it was directly thrown into the city of Jiexiu, as for whether it smashed the houses or hit the people in the city, it is really unknown.

Only a few stone bullets smashed on the city wall and the city, but the city wall of Jiexiu was all built with large green bricks, which was extremely strong, and the rammed earth city wall was not a grade at all.
