Su Yunchu nodded lightly and didn't miss the look of appreciation, exclamation and satisfaction in the old man's eyes. "What's wrong with the old man?"

"No, how long will it take the military division to see the crossbow machine?" the old man couldn't help but make a noise.

Su Yunchu said slightly, "within ten days, is it feasible?"

"OK, within ten days, I will make a crossbow machine satisfactory to the military division."

Su Yunchu nodded, "thank you, sir."

Earlier, Su Yunchu had an idea to copy the most famous divine arm crossbow in the Northern Song Dynasty to Daxin.

In her early years, since she was interested in the crossbow machine, she could not fail to understand the history of the crossbow machine. For the traditional and ancient crossbow machines, in addition to the Zhuge crossbow with unknown reality, what satisfied her most was the divine arm crossbow invented in the Northern Song Dynasty. According to the current Daxin level, it was no problem to copy the divine arm crossbow. However, Daxin was lack of technology in this aspect, No one can make more efforts in the improvement of the crossbow machine. Therefore, the use of the crossbow machine is not extensive, but declining.

Well, since she knows, she must make good use of it.

Su Yunchu gave the old man ten days, and the old man really lived up to his expectations. Ten days later, when Su Yunchu tried out a crossbow with a bow body of three feet three and a string length of two feet five in the school yard, almost everyone came to watch and wanted to see how fierce the more powerful crossbow machine they used in the legend could be.

At the place where Su Yun first stood, 350 steps away, there was a straw man, and 100 steps away from the side, there was an obstacle surrounded by heavy armor in the army. Su Yun first pointed at the scarecrow 350 steps away with a divine arm crossbow.

Almost all the people watching around jumped to their throat, that is Murong Ze. Looking at Su Yunchu's actions, they didn't change for a moment. They were afraid that they would suddenly blink and miss something.

Divine arm crossbow is a long-range weapon. It is mostly used to attack cities. Su Yunchu attaches particular importance to it.

But Su Yunchu was holding a crossbow machine and staring at the scarecrow 350 steps away. After more than a dozen breath, he still didn't send it out.

Murong Ze was so anxious that he almost wanted to seize the crossbow in Su Yunchu's hand.

Just when he felt that he could not bear to be hung by Su Yunchu, Su Yunchu finally let go. As soon as his right hand was released, the crossbow and arrow flew out rapidly and shot at the scarecrow 350 steps away.

The onlookers on the school field shifted their eyes with the direction of the arrow. In the expectation of almost everyone holding their breath, the crossbow arrow, no longer popular, directly hit the Scarecrow's head.

Seeing this, all human feelings could not be restrained. Qi Qi cheered and was very interested in the crossbow machine in Su Yunchu's hand.

Murong Ze, who knew Su Yunchu best, had already gone there earlier in the morning, "five... Alas, no, the military division, give me a try. It's amazing."

Su Yunchu put the crossbow machine in Murong Ze's hand and was very satisfied with the first arrow. However, before Murong Ze was ready to launch the arrow, Su Yunchu pointed to the obstacle surrounded by heavy armor 100 steps away on the other side and said, "shoot at them."

Murong Ze opened his mouth, "that's heavy armor, a hundred steps away!"

Su Yunchu's face remained unchanged, "I know, so I asked you to shoot them."

As soon as Su Yunchu said this, it was not only murongze holding the crossbow machine, but also everyone watching. It seemed that everyone did not believe that Su Yunchu would do such a thing. It was the limit that the crossbow machine could shoot more than 300 steps. However, it was heavy armor beyond more than 100 steps. The power of the crossbow machine itself had been weakened in the process of shooting, This is what Su Yunchu told them. Is it true that the military division is possessed today?
