Lin Yu now understood why their machinery was made in the arsenal, not only because the manpower and materials here were ready-made, but because the principles of these machines could provide them with ideas for making new weapons! Let's just say that this thing that looks like a crossbow and is not a crossbow, Master Qiu calls it a hidden weapon, because if this steel needle is shot into a person's body, it is really embedded in the skin and flesh, and it can even penetrate. The pen "Fun" Pavilion www.biquge.info not like an arrow, and there is a tail outside, which can be completely submerged!

Then Master Qiu took the two of them to see several new weapons, all of which were made from various principles and parts of the shoe repair machine.

"You can experiment with it, and then discuss it with the general to see if there is a possibility of large-scale manufacturing. Or make it and send it to the people who need it. Tianyu said.

Lin Yu picked up this thing that looked like a crossbow and didn't look like a crossbow, and after a closer look, this thing turned out to be a bit like a toy gun that he played with when he was a child! Bursts can be fired using a spring and bracket! You can send out five at a time!

"This," Lin Yu said with the "crossbow", "This steel needle is arranged in a line. If you move it, you need to release all five steel needles. ”

Tianyu looked at Lin Yu's thinking appearance, faintly excited, and even his eyes lit up. Seeing the inexplicable face of Master Qiu beside him, isn't this the legendary prince's woman? Why does General Tianyu look at people with this look?

"If a steel needle can already knock a person down, why waste the remaining ones?"

"Is there anything Miss Muffelin can do to save it?" Tianyu became excited, and even Master Qiu looked at Lin Yu seriously at this time.

"I think, this bracket is very good, so can you add another step, arrange these steel needles in a circle, just like the scale on the sundial, every time you flick the bracket, send out a steel needle, and at the same time, this circle turns a scale, and it reaches the position of the launch bracket. At this time, pull this switch again, and the second steel needle will be launched, and then go on a scale, and the third steel needle will be launched again. And so on. ”

"Oh, this, this, this is good! How I didn't expect that! Master Qiu was so excited that his hands trembled.

"And I think that the stronger the spring behind the bracket, the more powerful the needle will be. And if it's a round storage device, you can make it smaller. This thing," Lin Yu lifted up, aimed at a piece of wood on the opposite side, aimed, and then launched, and the five steel needles flew out in turn, because of the deviation of the hand trembling, four of them were stapled into the wood, and one hit the previous steel needle. "Look, anyone who hasn't touched a weapon can use it, if it is made more lightweight and small, as long as it is a little exercise for ordinary soldiers, it can achieve good results."

Tianyu took the "crossbow" and exclaimed, "I really didn't expect it to be like this!" I-" I was about to say that I wanted to go back and draw drawings immediately, but when I saw Lin Yu, the words choked back again, he was accompanying Lin Yu out to relax today, how could he say that he would go back when he went back?

Lin Yu didn't understand what Tianyu meant, so he only smiled at him.

But this Master Qiu was in a hurry, "General, go back and draw the sketch, and I'll do it immediately!" Oops, I really didn't expect Miss Lin to be so accomplished in this area. Master Qiu kept giving a thumbs up.

At this time, the other master also finished typing the parts he had at hand, he had just heard Lin Yu's drawing, and he was also full of curiosity about the kind of practice she said, and urged Tianyu to go back to drawing quickly.

Lin Yu smiled and said, "I've been visiting for a long time, otherwise let's go back." ”

Tianyu's face immediately showed joy, but when he looked at Lin Yu again, he hesitated a little and said, "Otherwise, I'll take Miss Lin for a walk elsewhere?" ”

"No need, I'm tired today, let's go back." Lin Yu said with a smile, she could see Tianyu's eagerness at this moment.

Tianyu was happy, talked to Master Qiu, and asked them to polish the parts they had just made, and then walked back with Lin Yu.

"That," as soon as he returned to the courtyard, Tianyu vomited.

"What's wrong?" Lin Yu asked.

"Well, I think-"

Lin Yu tilted his head to look at him, and saw that he couldn't come up with a reason, so he guessed, "Do you want me to sketch with you?" ”

Tianyu's face immediately showed a look of surprise and excitement, but then his shoulders drooped down again, and he asked weakly, "Is it okay?" ”

Lin Yu was amused by his appearance, "Of course you can!" Of course, it is necessary to make clear to you the ideas I proposed. ”

"Let's go!" As he spoke, he took Lin Yu briskly to the study.

Lin Yu's mood also improved. This Tianyu, in fact, is not as old as her in modern times, coupled with his dedication to the profession, many times in Lin Yu's eyes, she is like a younger brother with a simple personality, very cute. Even today, he also took care of his emotions, but when it came to the areas he liked, he immediately contradicted them. Very interesting.

After Lin Yu went to help him draw the picture, it was already time for dinner. The two of them didn't know it, and no one remembered that they didn't eat lunch.

Tianyu's own stomach rumbled first, and he remembered it in hindsight, and the whole person was sorry.

"Let's call it forgetting to sleep and eat." Lin Yu said with a smile.

Tianyu was even more embarrassed, she dragged Lin Yu over, but this afternoon, she didn't even pour saliva for Lin Yu, let alone snacks or something.

At this time, thinking that the Li family had also made dinner, Tianyu sent Lin Yu out in shame.

As a result, as soon as he went out, he saw Mu Yi looking at the gate, Lin Yu shouted, and Mu Yi turned around.

"My girl, didn't you say you went out to visit the arsenal? How in the yard? ”

Lin Yu smiled, "I'll be back after noon, and I'll go to the bookstore to draw a few pictures, and I'll finish it now." "Because the place where I want to go is the Arsenal Workshop, which is close to home, Mu Yi and the others are not allowed to enter anyway, so Lin Yu simply didn't let them follow. As a result, she came back for so long, and Mu Yi didn't know about it.

"And lunch is out for you?" Mu Yi asked.

Lin Yu looked at Tianyu, whose head was about to be buried in his chest, smiled, and said, "Yes!" Tianyu invited guests, but unfortunately it will take a while to come back, so I didn't call you. ”

"Then it's been so long since I've been back, I should let the slaves have a snack, milk tea or something, Tianyu definitely can't think of it, right?" Mu Yi didn't know Tianyu's identity, and he thought he was the same little guy as Tianxing, so he glared at him.

Tianyu's head hung lower and lower, and he felt embarrassed now. (To be continued.) )
