Shang Wen couldn't estimate what Yingyu was thinking at all now. He needed to find out why. Ask others if they are behaving unusually.

Shang Wen then ordered someone to quickly investigate what the students in this room had to do and what abnormal behavior they had before the explosion. He needs some auxiliary information to reason. Because the site has been badly damaged. I can't find anything special at all.

Even if there were, there were no special chemicals, such as testing nitrification reactions, and it was likely that such a large explosion would be a new type of gunpowder. Or rather. Shang Wen suddenly cleared his mind. Could it be that someone is working on a new explosive?

This, this can't be. These things, such as nitric acid, were all handed over to Bai Ai, and he sternly warned him not to do such dangerous experiments. Don't. Shang Wen thought of this. asked for a list of casualties, without his name, then where did nitric acid come from, could it be that it was refined by itself. Shang Wen was a little overwhelmed.

If this is really the case, then someone in the Qin State has already begun to study explosives. Then the explosion can be explained. But in this case, the cost is too great. So many people were killed at once. Shang Wen still felt a little distressed. These people are also considered talents, and they will all be reimbursed at once. It's a shame.

Shang Wen thought of this, and couldn't accomplish anything. Whenever someone loses his life because of scientific research, Shang Wen feels very sorry. The main thing is that the precious knowledge ends because of the end of life.

Shangwen returned to the car alone. The answer is almost already in Shang Wen's heart. It just needs some evidence to prove it. Yingyu looked at Shang Wen, who was a little lost, and felt that she should step forward to comfort her. So he took the initiative to find a little topic to divert Shang Wen's attention, but Shang Wen lay directly in the car.

Yingyu sat in the car speechlessly, wondering if this nerd was sad because his ears couldn't hear. Alas, think about it too, a person, all of a sudden, can't hear anything. That mood. Yingyu didn't know what to say.

"Your Excellency. Hey, the end will see Her Royal Highness the Princess. Zhang Han opened the car door a little recklessly and said.

"Oh, what's the matter?" Yingyu only now feels that she and Shangwen are alone in the car, a man and a woman, and the relationship is a little ambiguous.

"These are some of the things that the last general has just asked about the people he has just asked. Please take a look at it. Zhang Han said respectfully.

"Okay, I'll take a look at this palace first. Then give it to him. Yingyu took a few pieces of paper and said.

"Then he will stand down." Zhang Han left respectfully.

"Hey. Ay. Nerd, here's this. Yingyu took a few pieces of paper and tweeted Shangwen and said.

"What." Shang Wen was in a very low mood.

"This." Yingyu waved the paper with her hand.

Shang Wen took the papers. Quick look. Shang Wen read some useful information from it. The dead were cadets of sappers who had recently been sent west to build some roads. However, due to the mountainous nature and the fact that the weather was very freezing, the blasting method using black powder as the main body of explosives was very effective. So, they went on their own to find a more powerful explosive. This was the impetus for them to develop their own explosives.

They know a half-year-old child. Shang Wen guessed that it was most likely Bai Ai, because he had a large number of chemical experiment manuals in his hands. Moreover, he also knows the production method of sulfuric acid and nitric acid, and everything is going well. Judging from the information obtained at the end. They got a lot of animal fat. The results are already evident.

They made nitroglycerin explosives.

"Nitroglycerin." Shang Wen muttered in his mouth.

"They actually made their own nitroglycerin explosives." Shang Wen slapped the car door with his hand.

"What's wrong with you?" Yingyu grabbed Shang Wen's hands and said.

"Let go of me. Let me go. Shang Wen shouted loudly.

"Damn, they even made nitroglycerin explosives without regard for their lives." Shang Wen said loudly.

"Highly liquid explosives, the slightest shock can cause an explosion". Shang Wen said loudly.

"Whew." Shang Wen took a deep breath.

This breath was blown on Yingyu's face, Yingyu's hair was blown away, and she felt very hot in her face. The ears also feel hot. Yingyu let go of Shangwen. Shang Wen held his head in both hands.

Nitric acid and sulfuric acid were introduced. Explosives are a possibility. Although the former appears in small quantities, it is only necessary to collect it carefully. Sooner or later, explosives appeared. For this explosive, Shang Wen originally studied it himself. The premise is to master the method of large-scale production of nitric acid. Right now. The method has not yet been mastered. Nitroglycerin, a high explosive, has appeared. Shang Wen didn't know whether to be happy or sad. The Qin people's ability to explore independently has begun to actively explore the field of chemistry, which is a very happy thing. However, they were not at all afraid of the danger of explosives. Perhaps they are also unaware of the danger. Only those who have seen the power of explosives will control the danger. But their thirst for knowledge goes far beyond their sense of security.

Rushing to learn of a method of explosives that can increase the power of explosives, he dares to try it quickly. Ignoring the importance of security led to this disaster.

Shang Wen thought about it, and finally waved his trembling arm. Got out of the car. Told the sappers and all the trainees the reason for the incident.

Although Shang Wen can't hear anything now. But the cadets were clearly aware of the cause of the explosion, especially the Army, and for the first time, realized that there was something more powerful in the world than black powder. This has allowed them to expand their horizons again.

Shang Wen can't manage so much now. He needed to calm his mind. Then think of ways to solve these problems.

The door to explosives has been opened. Now is not the time to close it, but how to navigate the door to explosives. How to enter this temple safely. Rather than exploring in a hazy way, like Nobel or other explosives pioneers. That would only increase the number of casualties.

Nitroglycerin can appear, nitrocellulose can also appear, as long as the right fiber material appears, and then someone will develop thundermercury, picric acid, black sokin and so on. The explosives door has been opened. Then there is the upgrade of weapons, muskets no longer need flint, muskets are no longer called muskets. Rather, it is a slow transition to firearms. Because humanity has mastered a more efficient method. Mines, shells. Aerial bombs, rockets. It won't take long for these things to appear, and Shang Wen's mind is full of the shadows of these weapons.
