When they came back from cutting down a lot of trees, they invited a lot of carpenters, and through the drawings in the carpenters' hands, the soldiers knew what they were going to do, but they didn't know what to do with it.

When they saw Qin Er leading a large number of people to carry large stones up the city tower, the soldiers were even more confused.

Even Qin Er, who was in charge of transporting the stones, didn't know what this was for. He just did what he was told.

Ye Zhi knew what this thing was made by carpenters, and as a modern person who knew some knowledge of ancient warfare, she could see it. And the silence also talked to her. However, she was so busy working with Quiet on explosives that she didn't have time to tell people that it was called a catapult.

But because it was Xiao Changyi, the general, who asked him to do it, no one dared to slack off on this matter.

In just five days, more than 2,000 catapults were built.

The stones on the city towers, because there are many people carrying stones, in less than a day, all the city towers in Jingye City are full of large stones.

But Xiao Changyi didn't let them stop, and let them transport a lot of stones and put them in the city.

Every time he made a catapult, Xiao Changyi asked people to transport it to the city tower.

When the carpenter made the first catapult, Xiao Changyi tried the power of the catapult.

As soon as he saw that the catapult was placed on the city tower, Xiao Changyi asked him to put a big stone on the catapult, and then let a few particularly strong people press it down on the other side, and the big stone was instantly pressed and flew out.

Then there was a loud 'boom', which startled everyone.

Everyone hurriedly walked to the side of the city wall and looked down, and saw that the boulder smashed a big hole in the ground, this power, everyone was speechless, and everyone finally understood what this thing was going to do at this moment, everyone rejoiced, saying that with this catapult, it would be much easier to defend the city.

The catapult is so powerful, Xiao Changyi is very satisfied.

However, Xiao Changyi was worried that the enemy army would also penetrate Jingye City from the mountains, so he sent a lot of elite soldiers to guard there, and Qi Weimeng was in charge of this side.

Including the more than 100,000 soldiers who surrendered, Jingye City is actually equivalent to more than 400,000 soldiers and horses, and there are still 100,000 in Xilin City, Xiao Changyi did not transfer the 100,000 into Jingye City, if there was no catapult, maybe Xiao Changyi would transfer tens of thousands of them in, but now that there are catapults, Xiao Changyi still has not been transferred, and still let Xilin City maintain 100,000 soldiers and horses just in case.

The 100,000 soldiers and horses still let Liu Buli be responsible.

Xilin City and Jingye City are not too far away, if reinforcements are really needed at that time, Liu Buli can come over in time with 100,000 soldiers.

It's been five days, and the Chilin army thirty miles away has not yet attacked, but because the Chilin army is still thirty miles away, Xiao Changyi and none of them dare to take it lightly.

Jing Jing and Ye Zhi were still busy developing explosives.

Quiet is planning to blow up at least ten mountains of Chilin, that is, at least ten copies of explosives are needed, and now, Quiet and Ye Zhi have only made a large portion, and it will take a lot of time to complete the goal.

On this day, in the evening, Jing Jing and Ye Zhi came out of the room where the explosives were developed.

As soon as they came out, they saw Gong Jiechen squatting at the door of the room, holding a branch, not knowing what was written on the ground.

As soon as Gong Juechen saw Ye Zhi come out, his peach blossom eyes lit up, and he quickly threw away the branch in his hand, ran to Ye Zhi's side, and smiled: "Zhizhi, you finally came out, I've been waiting for you for a long time, you don't know what to do, and the people guarding the door won't let me in, I've never seen someone as vicious as them."
