Chapter 291: Lightning Mercury Appears

To solve the connection between the open space, there are some difficulties, Shang Wen thought with his chin in his hand.

Because the underground targets are different from the sky, plus the gunpowder weapons currently in use, it almost makes people feel collapsed. When the fighting time of both sides reaches a certain level, the fired gunpowder smoke can cover themselves and the opposing army. . Especially artillery, large-scale, concentrated and rapid firing. The smoke caused a headache for the artillery.

Shangwen has no good way to solve this problem for the time being.

Because when the air force and the ground are working together, radio has already appeared. The Air Force specially dispatched ground guides to assist the Army in combat operations. Obviously not now. Electricity only exists in the laboratory.

"This is a bit troublesome, but I think you can distribute a lot of flags or other things to the ground. Because I can't help it." Shang Wen said.

"En. Then I will go to the heavenly army to see what new tricks they have." Wang Jian said.

"I think you should go check it out. Also check out the subjects they train, so that you can arrange exercises." Shang Wen said.

"Well, thank you Mr. Qin for your guidance." Wang Jian said.

"Pointing is not counted, it can only be counted as thinking of something." Shang Wen replied.

"By the way, have you worked out the exercise plan now?" Shang Wen asked.

"Plan?" Wang Jian asked.

"Yes, it is the plan. For example, when and where the various arms of the army will be, and the troops involved. And how to exercise, who will play the role of the blue army and who will play the red army. How to judge during the exercise. Wait." Shang Wen said.

"That's right, I came back from the Celestial Army to ask about this question." Wang Jian said.

"Then I'll go and see the laboratory. Can you solve the open-ground contact. Otherwise, you will be in big trouble." Shang Wen said.

With that, Shang Wen and Wang Jian bid farewell to each other. Shangwen is going to the laboratory to try to produce something useful. But think about it, what can be done now, the lack of materials has reached an astonishing level, and it is difficult for a clever woman to cook without rice. The knowledge of one's own body is not enough without the materials.

Shang Wen had a headache thinking of this. Signal bombs and smoke bombs cannot be made, but fireworks bombs can be made. This was originally a holiday celebration, but now it can only be borrowed temporarily. However, this requires a lot of paper, and I am eager to use it now, and I can't manage that much. If possible, work on seeking other materials will begin later.

As soon as Shang Wen arrived in the laboratory, he found a person waiting there quietly. a stranger. Shang Wen didn't recognize it. But judging from his attire, he was from the Army.

"Are you?" Shang Wen asked.

"Report sir, I am the Engineering College of the Army Military Academy, and my subordinate is called Cao Xin. There is something under my command that needs an adult to check." Cao Xin said.

"What? Sit." Shang Wen pointed to the spring sofa in the laboratory and said.

"Dare not dare. This thing is obtained by subordinates using nitric acid, sulfuric acid and mercury." Cao Xin said.

"Lei Mercury." Shang Wen said in surprise.

"What? What did the lord say?" Cao Xin asked.

"The reaction between the two acids and mercury is thunderbolt. This thing is extremely sensitive and can explode. Where is the thing?" Shang Wen asked.

"Don't be afraid of adults, small discoveries, this thing cannot easily explode if it is placed in grease." Cao Xin said.

"Hehe." Shang Wen smiled.

"My lord does not suspect that his subordinates are joking." Cao Xin asked, bewildered.

"No, no," Shang Wen waved his hand.

"I am happy that adding oil, fat or paraffin to this thunderbolt can passivate it, that is, reduce its sensitivity. Moreover, the thunderbolt passivation treatment is good. It can change the status quo of the gun on a large scale. "Shang Wen said, supporting Cao Xin's shoulders and pressing him on the sofa. Cao Xin, who was scared by the flexibility of the sofa, did not dare to sit.

"It's okay, it's a sofa, it's more comfortable to sit on," Shang Wen said. Cao Xin sat down boldly.

"Do you need something to drink?" Shang Wen asked.

"No, no, the subordinates are not thirsty." Cao Xin said cautiously. Shang Wen had to pour a glass of water. Pass it to Cao Xin. Cao Xin thanked him. Shang Wen waved his hand to indicate you're welcome.

"The current muskets are all flintlocks. It is more troublesome to load, especially when filling the propellant. If the flint and other objects are not replaced in time, the musket will not catch fire. This is very bad." Shangwen sat down. Said.

"Now with thunderbolt, this problem can be solved very well. After a certain passivation treatment, this thing is made into a flash hider, and our musket can be changed to a percussion type. In this way, the launch speed is faster and the loading is also easier. It's very simple." Shang Wen said.

"Really, my lord." Cao Xin said excitedly.

"Really, moreover, if this thing is made into a detonator, it can be made into a detonating device. It has a wide range of uses," Shang Wen said.

"That's great," Cao Xin said.

"You can be regarded as an invention. Go back to Master Meng Yimeng and fill out the form. Apply for a patent, and if you want to research, try to avoid crowded places and pay special attention to safety. This thing is not a trifle. It will explode if you make a little movement, and your temper is very uncomfortable. Just like the last time you engineers made it." Shang Wen said.

"No. We must pay attention." Cao Xin said.

"They developed it too fast. They actually developed nitroglycerin, which has an explosive power ten times more than black powder." Shang Wen said.

"Last time, our engineer brothers filled in trouble for the adults." Cao Xin said with some guilt.

"Nothing, you should be encouraged and respected. Dynamite is not the same as other things. It is too dangerous. It will explode at every turn, and its power is amazing. You should pay attention to it." Shang Wen said.

"That's right. There are some more things, you take them back to see. Pay attention to confidentiality. This is confidential information." Shang Wen said and took out the manuscript.

"These are all the explosives materials I wrote. After everyone has read them, put them away and give them to me. They are all recorded in their heads. Don't say anything. Collect the experimental materials yourself. Some of them. You should also record the data. So that you can look it up later.” While talking, Shang Wen took out some notebooks and pencils and handed them to Cao Xin.

"These things you do must be kept strictly confidential. Remember to keep them secret." Shang Wen repeatedly asked.

"Yes, sir. Subordinates understand." Cao Xin said solemnly.

"En. After these explosives are done, they should be properly stored. Forget it. These things, leave them to me for preservation." Shang Wen said.

"Okay. Go and find Master Meng to fill out the form." Shang Wen said and waved.
