Xu San's words are not groundless, because if you read too many books in later generations, you will naturally have richer experiences.
He can naturally think of this commonly used trick.
After listening to Xu San's words, Dong Jinbao suddenly broke out in a cold sweat, "Who!?"
"I don't know either. I'm just guessing. Anyway, just be careful."
Dong Jinbao nodded, "Thank you!"
"You're welcome, we are all revolutionary comrades." Xu San wiped his sweat and said, "Get out, this room is too hot."
Dong Jinbao looked at Xu San, hesitated, and said, "Wait a minute."
Xu San stopped and watched Dong Jinbao fumble for two brown glass bottles from a cabinet.
The glass bottle is not big and there is no label on it.
But Xu San could tell from Dong Jinbao's cautious attitude that this thing should be quite dangerous.
Xu San took it and looked at the two bottles, one large and one small, both containing some kind of unknown liquid.
"What is this?" Xu San asked.
"The firecrackers you want."
Looking at the bottle, Xu San had the intention to open it and smell it, but after thinking about it, he decided not to commit suicide.
Looking at the bottle, he seemed to have an idea of what it was, so he tentatively asked: "**Glycerin?"
Dong Jinbao was slightly surprised at first, then smiled slightly, "You really know the goods!"
Regarding these things, Xu San also has a lot of knowledge reserves. After all, there are a lot of explosives in Hengdian, and he has also seen the actual objects.
Now that he knew what it was, Xu San opened the bottle, flicked his hand and smelled it, "This smell doesn't seem right?"
"It's better to combine two bottles together. It would be too dangerous to combine them directly to produce a finished product. After all, it's too hot today."
"That's right!" Xu San said, putting the two glass bottles in two pockets respectively, "It's just a little less, the two bottles together are 100ml."
"I can only give you so much, and it's based on how much you have helped Xinyi Tuan."
"Thank you very much!" Xu San cupped his fists and said thank you, without asking for anything more. He is a contented person, and he also knows that Dong Jinbao's work must be of great use.
Li Daitao was stunned, and Xu San also told Dong Jinbao what he knew.
For example, some superficial knowledge.
"I know an explosive that is a little stronger than this, called RDX. The chemical name is cyclotrinitramine, and the chemical formula is 6o6. It can cause combustion and explosion when exposed to open flame, high temperature, vibration, impact, and friction. It is A highly explosive explosive with extremely powerful explosive power, 1.5 times more powerful than TNT. The most important thing is that it is more stable than this! You can study it when you have time." Xu San pointed to the bottle in his pocket and said.
"What about the craftsmanship?" Dong Jinbao asked excitedly.
"I don't know. I just saw it occasionally in an academic magazine. That's all I wrote about it in that book."
"Which magazine?" Dong Jinbao asked.
"A medical magazine. This thing was first invented to make medicine, but it accidentally turned into an explosive. But I forgot which one, but it was an English magazine. I saw it at Yanjing Army Hospital." Xu San He said perfunctorily.
"Then the magazine doesn't write anything about craftsmanship?"
"How could it be written in this magazine? But I still roughly remember the molecular formula." Xu San said with a frown, because he only remembered the molecular formula in a vague way.
"That's okay. If you have the molecular formula, you can avoid a lot of detours." Fatty Dong suddenly became excited and took out a pen and paper and handed it to Xu San.
Xu San drew the molecular formula from memory, "I'm not sure about this. You must be careful when doing experiments."
"This is natural. I cherish my life very much and never make fun of my own life." After saying that, he picked up the molecular formula drawn by Xu San and looked at it again. "It seems that this formula is stable enough, that is. ....It’s not possible to combine the conditions here.”
"I can't help you with this. If you want a regular laboratory, just ask Miss Ji for help. Her family definitely has connections."
"I'm sorry to trouble her again. Our new group already owes her enough. And this experiment is a bottomless pit." Dong Jinbao said helplessly.
Xu San smiled and patted him on the shoulder, "Don't think about it now. Go out and get some fresh air. I'll bring some popcorn. I guess you like it."
In the backyard, Dong Jinbao brought a bucket of black and pungent soup to Miss Ji, then took out a white mask and handed it over.
Miss Jieda took the mask, took off her coat, exposed her fair arms, and then gave Xu San a provocative look.
Xu San turned a blind eye, grabbed a handful of popcorn and handed it to Dong Jinbao, "Try it."
Dong Jinbao looked at Ji Wushuang and asked for her opinion.
"Eat!" Ji Wushuang said, inserting his arm into the barrel, and then began to inhale, looking very sour and refreshed.
"What does it feel like?"
"It's numb, itchy, and hot! It's much better now. In the first two days, I couldn't hold on for ten seconds." Ji Wushuang complained while inhaling.
"Only by feeling can it be effective." Xu San also rolled up his sleeves and inserted his arms into the bucket.
After about five or six seconds, he felt a numb feeling, like the feeling of fish therapy in later generations.
After soaking for a minute, Xu San took out his arm and said, "Isn't this quite comfortable?"
Ji Wushuang curled her lips and said, "You can try it again after holding the rifle for an hour. The more tiring this medicine is, the more irritating it will be."
"As long as it works, otherwise you may not be able to persist." Xu San said.
"Who are you looking down on? Without this medicine, I would be the same." Ji Wushuang said proudly.
After lunch, Xu San sat in the study, picking his teeth and looking at Miss Ji's chemistry homework.
But Xu San felt that this homework was not done by her, because there was nothing wrong with it.
Xu San remembered that her chemistry score was in the mid-30s, which was worse than physics, but how could she become so good after not seeing each other for the past few days?
He raised his head and saw Dong Jinbao who was serving tea and pouring water.
Xu San smiled and immediately understood what was going on.
However, this is difficult to reveal.
"Hey~" Xu San sighed.
Miss Ji, who was leisurely drinking tea, heard Xu San sigh and immediately rolled her eyes at Dong Jinbao. It seemed to mean, aren't your answers guaranteed to be correct?
Dong Jinbao also gave a confused look, meaning, yes, the questions he asked were not difficult.
Pretending not to notice the flirting between the two, Xu San said softly, "Wushuang-chan has made great progress, and I didn't find any mistakes. This deserves praise!"
"Haha~ This lady is awesome!" Ji Wushuang laughed triumphantly, then she stared at Xu San and asked, "Is this a good performance?"
"That's right!" Xu San said reluctantly.
"Then it's time to teach me the breathing technique you mentioned." Miss Ji asked expectantly.
