Winter morning is a good time to sleep in. Hua Wenxiang hid in the house, her long snow-white legs on the quilt, and her disheveled hair has no lady image.

Ye Xiang stayed up all night and his feedback on the spring was always unsatisfactory.

In order to restore the Dragon teeth to their former power, ye Xiang brought Ye Lin's Dragon teeth.

After repeated comparison, ye Xiang understood.

The original dragon tooth relies on the high-pressure feedback of the air pressure chamber for power feedback.

This kind of dynamic feedback has its own release of kinetic energy with air pressure. The kinetic energy of the connecting rod on the composite is greater than the previous kinetic energy.

The feedback of the mechanical spring can only ensure the original kinetic energy, not amplify the kinetic energy.

Under continuous firing, the kinetic energy is decaying. The kinetic energy of feedback will become weaker and weaker.

Ye Xiang remembered the submachine gun thousands of years ago. The sound of shooting was like setting off firecrackers.

At the moment when the bullet is fired, the transmission of explosive kinetic energy makes the firing pin return. Unless you release the trigger and block the firing pin, or the bullet is finished, the gun will not stop.

The principle of pistol is almost the same as that of powerful crossbow.

The explosive transmission of the bullet and the mechanical spring feedback at the lower part of the barrel push back the striker repeatedly.

Therefore, as long as the safety of the pistol is opened and the bolt is pulled, even the empty gun can repeatedly stimulate the firing pin.

Stroking this idea, ye Xiang formed a whole set of ideas in his mind.

High pressure power cabin, spring linkage power transmission, compound gear lever, reverse auxiliary propulsion, simple small compound high pressure cabin.

The more he thought about it, the more excited Ye Xiang pulled out a large piece of irregular kraft paper and a charcoal pen. Taking the connecting rod as a ruler, he focused on drawing drawings.

The light of the three pole oil lamp went out, the faint smell of grease drifted away, and the sun shone on Ye Xiang through the window.

The charcoal pen in my hand moves rapidly, clouds and water flow, and mechanical structure drawings, together with Arabic ruler numbers, a drawing of an unparalleled God crossbow, were born.

Finally, in the design value of the crossbow, the metal crossbow is very short. Instead of the bold cross free tail design, it uses the concave tail design. Rifling is designed in the crossbow tube. After the crossbow flies out of the crossbow tube, it will rotate like a bullet.

After all this, ye Xiang felt a burst of emotion in his heart. You should know that the weapons he used before were driven by pure energy, not pure cultivation.

Ye Xiang found it quite challenging to think of citrus as a weapon design subject to the limitations of current technology and runes.

Thinking so much, ye Xiang went into the forging workshop!

Feimi is busy here and is refitting a crossbow.

Seeing ye Xiang running with red eyes, Mitu touched his stomach and said with a smile, "what's the matter, boy, didn't sleep all night?"

Ye Xiang stepped forward quickly and said with the memory of these steam machines in his mind, "hydraulic lathe, pneumatic shaping machine, forging machine, and car saw."

Then he took the drawing on the table and said, "I now need a new linkage preaching system, which adopts closed air compression spring setting, close ball slide rail and push-pull shell."

Mitu was confused by Ye Xiang. He could pick up the drawing on the table. Feimi's eyes opened wider and wider, and when he saw the last sound, he cried, "divine work! Did you draw this? "

Ye Xiang was playing with the lathe and asked in surprise, "can you see the numbers above?"

Mitu smiled, "isn't that the number of Ximang? This often appears on the craftsman's drawings. "

Ye Xiang felt relaxed and said, "I use millimeter units."

This time, I was surprised to change to a meter chart, "what you drew is actually a millimeter chart. It's powerful. It's only a great craftsman who can do it. Sure enough, he deserves to be the son of master Ye Lin. he's awesome! "

"Uncle Mi! I don't know much about these big guys now. Would you please help me? "

Then ye Xiang pointed to the three parts on the drawing and said, "this, this, and this, I need it now. I have to adjust the Dragon teeth in the afternoon!"

Feimi looked at the three parts on the drawing, patted him on the back and said, "go to the chair over there and have a rest. These three parts won't take much time."

Ye Xiang was pushed to his seat by feimi. After watching feimi start processing parts, he carefully observed each other's methods, and immediately felt relieved that his whole body was also relaxed.

I picked up the drawing on the table next to me and looked at it for a few times. I suddenly felt that my eyelids were like Mount Tai, so I fell asleep.

"Would you like to try this?" Feimi's fat face suddenly appeared, and ye Xiang suddenly woke up.

As soon as I opened my eyes, Mitu looked at Ye Xiang with tears on his big face. That expression was an impulse of excitement, worship and worship.

Ye Xiang asked suspiciously, "what's the matter with Uncle Mi?"

Mitu took a lot of drawings and said excitedly, "you can draw when you sleep. You are the first person! Look at these drawings, the idea of these crossbows and arrows is really awesome.

Give me some time and I'm sure I can do it. Can you give it to me? "

Ye Xiang grabbed the drawings and looked at them one by one. Then he thought that when he fell asleep, he had a dream. In the dream, he vaguely summarized all the available technologies that had appeared here.

And I seem to have drawn it in my memory. Is it true that all this is true?

But when did you have the habit of sleepwalking

"I painted all these?"

"There are only two of us here. I'm making accessories for you. Aren't you a ghost?"

Ye Xiang put down the drawings and said in a deep voice, "the drawings of the mechanical crossbow and these drawings are for you. Watch and do it yourself!

But after a while, I may use the mechanical crossbow on the drawing. Uncle Mi needs to be careful! "

Mitu jumped three feet high and called, "ask again, can I take these drawings and works to assess the master craftsman?"

Ye Xiang was stunned and asked, "what about the assessment of the master craftsman? These drawings? Uncle MI, you know, the secrecy of a weapon determines the hidden strength of a combat group.

So I don't suggest that you take the master craftsman assessment now.

When our mercenary regiment uses this weapon, it will become famous in the mercenary world.

After everyone knows the existence of this weapon, it's the same to apply for a master craftsman.

In this way, the interests of the mercenary regiment and your personal interests will be maximized. What do you think? "

Pop!

Mitu clapped his hands and shouted, "isn't it? When I become famous, the name of a great craftsman will be readily available. "

Ye Xiang picked up the accessories on the table. "I took the things away. The drawings must be kept. I'm not sure I can draw it a second time!"

"This is a baby. Don't worry!" Fat rice patted his chest and promised happily.

At noon in winter, Hua Wenxiang was still sleeping. Her little face was flushed by the sun through the window.

Half asleep and half awake, she said in a dream, "I'm not a waste, I'm not a waste! Big sister, second sister, don't underestimate me. I said I wanted to be a mercenary and a mercenary king. "
