Chapter 188: Skydiving training begins

Just do it. Shangwen immediately looked for a place to make limestone. However, when he was about to do a big fight, Li Xin was already waiting outside the door at this time.

"What's the matter?" Shang Wen asked.

"My lord, no, sir, we have finished the tour. What should we do next?" Li Xin asked.

"What?" Shang Wen asked with some confusion. But immediately understood. The training of the Celestial Army is the main person in charge, and none of these subordinates has been to the sky. How to train. It's just a joke. How do they know what to do. I hope they have initiative, they have to understand. They can only simply understand the principle and processing of hot air balloons. Make. The operation is not known at all. How to train.

"Okay, I get it. By the way, you go find Bai Ai, I have something to explain." Shang Wen had no choice. You must do this yourself. And no one can take his place. But this aspect of chemistry has only begun. Can't stop. These things had to be handed over to the child Bai Ai, which is also Shangwen's plan to make Bai Ai a certain degree of interest in chemistry.

Shang Wen quickly took out his notebook. Begin to write out how to make cement.

In order to prevent Bai Ai from not understanding at first. Shang Wen wrote about the properties of cement. Powdery hydraulic inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or better harden in water, and can firmly bond sand, stone and other materials together.

Shangwen is going to make Portland cement, and the ratio of this kind of cement is best to be made at a ratio of three to one. The best ratio is then tested by chemical experiments. Shang Wen really couldn't get away now.

After Shangwen finished this, he felt that one day was not enough, and it was best for Bai Ai to find something else to do. Shang Wen thought of the dry distillation method, the reaction process of heating and decomposing solid or organic matter under the condition of isolating air. This is the earliest chemical method that mankind is familiar with.

Shangwen made Bai Ai dry distilled sulfuric acid, nitric acid, and the wood essence produced by dry distilling wood was methanol.

Bai Ai came soon. Shang Wen immediately tore off a few pages of his notebook paper,

"Listen. For these things I asked you to make, don't grab them directly with your hands, but use wooden clamps to get them." Shang Wen looked at Bai Ai's eyes and said solemnly.

"What I asked you to do is chemical things. These things are extremely corrosive. If the human body is touched, it will rot and burn. Be sure to try these things. You just need to put them in a jar and take them back carefully. Got it. Understand?" Shang Wen grabbed Bai Ai's shoulder and said.

"Understand, sir." Bai Ai said firmly.

"I know you have a strong curiosity, but now this is not the time for curiosity, these things are too corrosive and will kill people. I don't want things that shouldn't happen, understand?" Shang Wen emphasized again. Because these things should have been done by oneself, but now they have to be done by a child. Shang Wen is really reluctant. After all, without a little chemistry knowledge, it is still dangerous to do such an experiment. Moreover, this is still a child.

"My lord, I promise." Bai Ai nodded and said.

"Okay. I have written this method on it. There are words that I don’t know. I will send a craftsman to go with you. Don’t let anyone touch it, understand? And if someone touches it, it’s best to use wet Wipe it dry with a rag, then rinse it again, that's all when you are done. Here you are, take this." Shang Wen handed the paper to Bai Ai.

Bai Ai left with a craftsman immediately. Shang Wen followed Li Xin to start training pilots. The first group of key members of the Celestial Army.

Thirty-three officers are in good condition.

Shangwen walked to the thirty-three officers. The team stood in two rows, did not stand at attention, and waited for a while. This was because even the Musketeers did not learn this, let alone these officers. It seems that these things have to be taught to their instructors first. Thinking of this, Shang Wen felt that the following training syllabus should be formulated. These most basic etiquettes should also be supplemented in it.

These details will be explained later.

"Everyone is in a very good state of mind. Very good. What the heavenly army needs is such a state, to maintain this state at all times." Shang Wen used an indifferent speech as his opening remarks.

"Well, today, we will start a training session. First of all, I want to ask everyone, what if your aircraft breaks down and cannot land safely from the air after you ascend to heaven? You can say whatever you want." Shang Wen asked all of a sudden.

"If so, I'll jump down." "That's so high. Do you dare to jump." "That's, maybe you can survive." The officer said fiercely.

"Yes. You must jump down." Shang Wen said loudly.

"And jumped down alive." Shang Wen continued.

"More Newton's laws, and some common medical knowledge." Shang Wen knew that these laws had to be explained. But it is not the time yet.

"What I said, you will learn later. The human body can only bear a height of about two feet or less. When this height goes up, you will kiss the earth fiercely. Then, your head and internal organs will fall. It's messy. Do you want to jump?"

"No, if you give it to me, I won't be able to jump. I will stay there, maybe there will be a chance. But there is one thing that can help us."

"Come here." Shang Wen said. He took the parachute from Li Xin, as well as a helmet and paratrooper boots.

"With these equipment, we will ensure that we will not jump from such a high place and fall alive to death."

"This." Shang Wen picked up the parachute and said.

"It can slow down our landing speed. It bears most of the weight of our human body. Use air resistance to slow down our landing speed.

"This." Shang Wen picked up the paratrooper boots.

"It can be guaranteed that our legs and feet are broken after landing. You know, the army does not want a group of lame men to fight." Shang Wen said jokingly.

"Hahaha." The officers finally accepted Shangwen's humorous statement and burst into laughter.

"Paratrooper boots can avoid this. Although we have parachutes, we must know that the impact of falling from a height is still great. We must be soberly aware of this."

"And this, a helmet. There is a leather lining inside. It can prevent our head from being severely traumatized." Shang Wen said.

"Speaking of this, we have to mention the last time there was an accident. Last time, it was because there was no safety system. After an airship made a direct landing from a height, four people died. Most of them had cerebral hemorrhage. That is. We have had congestion in our head. We have no craniotomy and there is no cure."

"Well, training starts from safety." Shang Wen said loudly.
