Nie Fenghua looked at the person who came, obviously very satisfied with Situ Qianzhi's approach, and cast a grateful look at him.

There are some people in this world who will meet her requirements and do anything for her, even if they don't know what she is going to do next.

Such a person, I'm afraid there is only one Situ Qian in the world, right?

Nie Fenghua sighed secretly in his heart, maybe the feeling between them was coming back step by step, but he always felt that he couldn't go back to the Jianyi Courtyard again.

Although there are some regrets, it feels good to get along with each other in such a way of using and calculating, maybe with the personalities of the two of them, this way of getting along is the most suitable for them, right?

"Take it out." Situ Qianzhi looked at Nie Fenghua, and said to his subordinates, "The princess brought some things to show you today, which should be helpful to everyone." ”

Nie Fenghua smiled and took the package in Xue Zhan's hand: "In the past few days, the brothers took me to visit the barracks, and I found that there were fewer weapons for long-range attacks in the barracks, and the farthest was bows and arrows, but if you attack the city, it is really difficult to shoot arrows to the high city tower by hand, so I went back and drew this." ”

She opened a picture of a cart with a large iron bag on the back of the cart with a large stone in it.

"This is a trebuchet, two or three soldiers jump down at the same time, you can turn this iron pocket up, throw the big stones here, control it well, this stone can hit the city tower no matter how high."

"And this is a crossbow, and in the same way, it takes more than three soldiers to open this string, which can shoot at a long distance, even through a stone wall."

Situ Qianzhi listened to it with relish, and looked at Nie Fenghua: "These things are good, but it seems that it takes a long time to practice some soldiers to be responsible for these, and a very strong tacit understanding is also needed." Also, there are trebuchets and crossbows, but your attack power is stronger and you look lighter. ”

"I know." Nie Fenghua nodded, "For these, I just drew some improvement drawings, and the focus is here......"

She unfolded another picture: "It's still a trebuchet, but now it doesn't need to be manpowered." ”

Situ Qian was puzzled: "How can you vote without manpower?" ”

"Gunpowder!" Nie Fenghua spit out two words, "When the gunpowder explodes, it has a huge power, it can shatter many things, not to mention, but at the same time, it can also say a lot of things and push them far." ”

To put it bluntly, it is the principle of launching rockets, but it is difficult to explain with the ancients.

She had proposed some of these things in her previous life, although she was a traverser, but after all, she was not pouring arms, but Xiao Qi immediately carried out the real thing after hearing about this, and as a result, she had these gunpowder trebuchets and crossbows in her hands now.

For this matter, she should be grateful to Xiao Qi, he let some of the ideas he casually mentioned become a reality, and now it has become a tool for her to avenge Jin'er Chongwen.

Sure enough, Situ Qianzhi's eyes lit up: "Have you tried it, is it feasible?" ”

"I probably have an idea, and I've done some real things, but the site is not big enough, and I still need to do some more, and I think it should be done soon."

In her previous life, she had memorized the numbers in her mind, and she followed up all the way from the beginning of the idea to the process of making zuò, and she would carefully study every detail.
