Guo Kai was helpless when he bumped into walls everywhere, so he had to find Li Si again. Because only Li Si can contact Shangwen.

Shangwen didn't get up until morning. Looking at the drool full of paper. Shangwen was embarrassed to show it to those craftsmen. But forget it. The one with a lot of saliva happens to be the one with the oboe. Shangwen was reluctant to draw another one anyway.

"Oh, that's it. Anyway, it can be used." Shang Wen had to sort out all the drawings. There is also a part of the sheet music. But these staffs don't know how to teach others. There is no way, you have to copy the explanation and meaning of the staff.

While Shang Wen was copying. There was a "clang clang" trick sound.

"Who." Shang Wen quickly gathered up.

"My lord, I, Li Xin." A strong male voice came from outside the door.

"Oh. Li Xin." Shang Wen finished packing.

"Come in." Shang Wen said.

"Here." Shang Wen sorted out the case.

Li Xin strode in. Then he bowed on one knee and marched in salute.

"I will see your lord at the end." Li Xin marched in salute.

Shang Wen was hurriedly cleaning up the case.

"Get up quickly. Don't be restrained. There are not so many rules here." Shang Wen waved his hand.

"Here." Li Xin said when he got up.

"Okay, don't be restrained. Feel free to. Relax." Shang Wen saw Li Xin a little nervous. Just said.

"Master Wei Liao sent you here." Shang Wen asked.

"Yes. Master Wei Liao said. Your lord needs manpower here. I will send the future." Li Xin said.

"That's it, didn't you say anything specific? Don't stand, just sit down." Shang Wen waved his hand.

"Here." Li Xin sat down still somewhat cautiously.

"Master Wei Liao didn't say anything." Li Xin replied.

"Do you know that Da Qin has an airship that can fly to the sky?" Shang Wen asked directly.

"This will eventually be heard." Li Xin replied.

"En." Shang Wen agreed.

"Tell you the truth. Da Qin wants to build an army that can fight in the sky." Shang Wen said while looking at Li Xin.

"What?" Li Xin said in surprise.

"Nothing. It's going to happen sooner or later. There is nothing to be surprised. Moreover, I will tell you. This army is different from other armies. Moreover, the king has a very strategic vision and separates this army from the beginning. Self-contained army. Do you understand the meaning of this?" Shang Wen asked.

"The last general..." Li Xin hasn't answered yet, Shang Wen has already signaled Li Xin not to speak.

"The heavenly army is different from other armies. Because their fighting place is in the sky, and at the same time, they can dive down like an eagle to attack targets on the ground." Shang Wen said.

Then Shang Wen stood up. Walked to Li Xin's side. He patted Li Xin on the shoulder and said: "The sky is vast and boundless. Eagles can fly into the sky because they are free." Shang Wen paused.

"You are so restrained, it seems that you can't fly into the sky." Shang Wen said with a smile.

"The last general, the last will understand." Li Xin said with a fist.

"Here again." Shang Wen said.

"You are so cautious, then I can only send you to do ground work." Shang Wen said half-jokingly.

"Ground handling?" Li Xin asked.

"Yes, ground work. Ground work needs someone like you to be rigorous and serious. Don't you want to." Shang Wen asked.

"Think about it." Li Xin said immediately.

"That's right. So now, you must relax." Shang Wen said.

"In order to be distinguished from other services. From now on, I will call my boss or a person with a higher rank than himself a chief. Do you understand?" Shang Wen said.

"Here, sir. Sir." Li Xin corrected.

"There's that. Change to yes." Shang Wen said.

"Understand." Li Xin agreed.

"Well, let's say something serious." Shangwen began to return to serious topics.

"Due to the last accident, our only airship has crashed. The new airship is still under design and research. This involves many technical research and development." Shang Wen said solemnly.

"That is to say, the number of aircraft we can lift into the air is zero. That is, our space army has just been established, and we are facing the situation of no equipment." Shang Wen emphasized.

"Da, sir, what do we need to do." Li Xin said immediately.

"We need to start this research. The Celestial Army depends on technology. Officers must understand technology. So, the next thing is to select officers and take them to the research airship to understand. To learn." Shang Wen said.

"Selected officers. Must be like eagles. Free, bold. Innovative." Shang Wen emphasized the last three words.

"Yes, sir." Li Xin has adapted to this name.

"Very well, the Celestial Army without aircraft is not called the Celestial Army. We need to design a kind of hot air balloon for teaching. I will give the drawing to the person in charge after a while," Shang Wen said.

"After you have selected the officers, I want to re-examine them. Then, you teach them a lesson, mainly to make them understand fundamentally that the Heavenly Army is different from other services." Shang Wen said.

"Okay. Go ahead and go ahead." Shang Wen said.

"Yes, sir." Li Xin said with a fist. Seeing Li Xin's behavior is very weird. Shang Wen wanted to laugh, but Shang Wen still held back. After all, his identity is different now. If you laugh in public, it will leave a bad influence on your subordinates.

"Go." Shang Wen waved his hand.

After sending off Li Xin, Shang Wen began to draw a hot air balloon. Some parts can be used in common with the airship. There is no need to worry about this. And hot air balloons are much simpler than airships. The first is that it is relatively simple to design and manufacture airbags. To make the airbag of the airship, the inner frame must be made first. And as the airship gets bigger and bigger, Shang Wen doesn't know how long the hot air airship that relies on heat to provide lift can be used. Is it right to use the more dangerous hydrogen? Forget it. take it easy. Shang Wen thought.

All of a sudden transition to a hydrogen airship. This requires a very large technical reserve, which is obviously impossible at present. It can only use the hot airship to slowly accumulate such technology. And the heavenly army has just started. Great pace. It's not easy to walk. Sooner or later I have to come back and start anew.

Shangwen finished copying the explanation of the staff. Holding the drawing. Just go back to the arsenal. Some projects must be launched as soon as possible, time is not waiting.

After explaining everything, Shang Wen came to the place where the steam engine was developed. I don't know why, several days have passed. The steam engine has not come out for a long time. Shang Wenwen wants to train the craftsmen, but now he has to intervene.
