At this time, Sanbao was a little hesitant. He didn't know how to face Xiaoying. He always felt a little sorry for her. Maybe he needed to straighten out his thoughts before he could decide how to face her.
He saw Xiaoying walking towards him and hid immediately. But this time Xiaoying was really angry, not only because he couldn't find the three treasures, but also because he saw him.
On the table outside Sanbao's house, there was cotton wool from his infirmary hanging out. No wonder he couldn't find it. It turned out to be brought by Sanbao. It should have been taken away by him when he took the initiative to check the wound last time. He actually went there only
She did this just once in the infirmary, which seemed to have a purpose. Xiaoying thought that Sanbao didn't want to see her and made these to bandage the wounds. She angrily took away all the cotton wool.
Xiaoying was still angry when she returned to the infirmary. She vented all her anger on the pile of cotton wool and began to tear the cotton wool into pieces...
"Are you making alcohol cotton balls?" Ding Wan asked.
"Yes." Xiaoying could only respond.
"I just need it for an injection." Ding Wan said, taking some and putting them into the alcohol bottle.
"By the way, have you seen your three treasures?" Ding Wan asked as she packed the medicine box.
"Who rarely sees him!" Xiaoying replied angrily.
"Okay, I'll go find him for you later." Ding Wan said, carrying the medicine box, "I'll give the factory director an injection, you wait here."
Not long after Ding Wan left, even Xiaoying didn't expect that Sanbao actually barged in. Xiaoying was satisfied that he came so quickly. It seemed that Ding Wan told him that he was angry.
Xiaoying deliberately turned her head away, but as soon as Sanbao came in, she asked eagerly: "Xiaoying, did you bring the cotton wool at my door?"
"You should have stolen it from me. It just returns to the original owner." Xiaoying immediately replied.
"These are it?" Sanbao said, "Don't touch these, give them all to me."
"What the hell are you doing?" Xiaoying looked at his serious expression and couldn't help but ask.
"We'll talk about it later." Sanbao, who was still unsure of the bottom, just said, and then asked: "Why does it look like there is less?"
"Ding Wan took it," Xiaoying replied.
"Where did she go?" Sanbao immediately asked nervously.
"She went to give the factory director an injection." Xiaoying saw that Sanbao's nervous expression didn't seem like a joke, so she replied honestly without being angry.
"I'm going to come back." Sanbao said and left. Xiaoying, who didn't know why, felt strange, so she followed behind.
The two of them were looking at each other and were about to walk to the factory director's room. Suddenly, there was a bang in the room. The windows of the house also suddenly lit up.
"No!" Sanbao immediately broke in. In the room, the shocked Ding Wan was staring blankly at the brazier in front of him. The brazier had been overturned to the ground, and the charcoal fire had fallen to the ground. The factory director on the side was also very surprised. He
He came over and asked, "Nurse Ding, are you okay? What did you throw in there?"
"I'm fine." Ding Wan, still frightened, replied, "I just threw in a piece of cotton wool that had been wiped and disinfected."
"Where's the rest? Give it to me quickly!" Sanbao, who had just come in, urged with joy on his face when he saw all this.
"Sambo, what's going on?" The factory director asked immediately when he realized that it was related to Sanbao.
"I made the collodion." Sanbao replied, "I didn't expect that Xiaoying took it away."
"You still blame me, why didn't you tell me?" Xiaoying, who followed, said.
"Collodion, what is that?" asked the factory director.
"It's explosives, high explosives." Sanbao replied: "But luckily it wasn't placed in a sealed container, which would only cause rapid and intense combustion."
"High explosives!" the three people asked in surprise.
"It can expand 470,000 times in an instant. Of course it is a high explosive." Sanbao said proudly.
"Why didn't you tell me earlier?" The factory director was a little annoyed but also felt relieved.
"Why don't you let me do it with you?" Xiaoying said, "It used to be done by the two of us."
"I don't know if I can succeed." Sanbao replied: "I don't have much nitric acid and sulfuric acid, and I don't know the concentration. I can only soak it multiple times for experiments. Is there any absorbent cotton? I can only use cotton wool.
Already."
"I think the effect just now is good." The factory director immediately said: "Let's make it into explosives and try it."
"Okay." Sanbao responded.
Ding Wan's unexpected action speeded up the production of Sanbao. Originally, he used a one-to-two mixture of nitric acid and sulfuric acid to soak the cotton wool, but the subsequent cleaning needed to be dried, and using alcohol speeded up the cleaning and drying.
The explosive power of guncotton is amazing, and it can be used as fuse and propellant. With the support of superiors, Sanbao has initially solved the problem of the power of making grenades and landmines.
