"Come here to get the things," Tinglan shouted inside. He was deliberately shouting to the big room. Sure enough, I didn't know how long the ears in the big room were. Qi Pengyuan ran away from it.
When he came out, he saw Tinglan, he hurriedly ran over, "Brother Tinglan, have you brought me a gift?" He blinked his eyes, and Tinglan was so childish that he couldn't help but shake his head, and he really thought it was
My younger brother is in pain.
"Of course, you have the most," Tinglan took out a large box from the carriage.
Qi Pengyuan took it and opened it and saw, "Wow, the four treasures of Su Yage's study, I won't sell it, Brother Tinglan, how did you get it?" He wanted this for a long time.
"This..." Tinglan touched his chin, "Don't you know, Su Yage is your elder brother-in-law's property. I just need to report your elder brother-in-law's name."
"Really, why didn't I expect it?" Qi Pengyuan looked annoyed.
"It's enough to know now," Tinglan patted Qi Pengyuan's shoulder, "By the way, you can take it with you from your master, and just say my son asked me to take it."
"I understand," Qi Pengyuan happily took the things he brought to Mr. Chen, and ran away without a trace.
Tinglan took down the gifts in the car and sent them back to Qi and Gu family respectively.
How could this big room feel comfortable when they see that they have no share of themselves? They scolded and shouted at home. Qi Da went to bed without seeing him. His face had been thrown away long ago. The dead pig was not afraid of boiling water and wanted to throw it away.
Just throw it away.
Tinglan finished the gift and patted it. Okay, it won’t matter to him next.
Qi Youer walked out, "Have everything done?"
Tinglan smiled and then stroked his hair casually, "It's already done, look, it's all here. He took a photo of the carriage, and the half-carriage is not bad."
Qi You'er opened the curtain of the carriage and saw that it was indeed the materials of the half-carriage. She was still worried that Tinglan would not be able to buy enough, because she only knew the formula, but she had never tried it. She was afraid that she would not succeed once. Now she looked at it.
Come on, these things are enough for her to experiment many times.
"Yeah, it's very good," Qi You'er put down the curtain and looked into the distance. There was a clearing ground behind the mountain of Shitou Village, where no one went on weekdays, so it was just right where to go to test it.
"Tinglan, I'm useful to help me move these to the back mountain."
"It's useful, what's the use?" Tinglan didn't understand, "What are you going to do?"
"Secret," Qi Youer put his hand on his lips. This is of course a secret, and it is a big secret. If it succeeds, then she will be equivalent to launching changes in this era.
"Okay," Tinglan spread his hands, "Don't worry, I'll ship it as soon as possible," Well, as long as she is in a good mood, he can help him, as long as he doesn't make trouble for him, and,
Don’t wait for my elder brother to come back every day like my sister-in-law. I feel so sad when I see him.
Tinglan has always been very efficient in his work. He had already transported it to the back of the mountain in less than an hour. There was an open space here, which was large enough and quiet enough. Qi Youer tidied up his clothes and entered the mountain alone.
She often came to this mountain when she was a child, where she picked the big materials and destroyed it. She really couldn't bear to leave it. However, now she doesn't want to leave it anymore, and it will grow it next year.
One nitrate, two huang and three charcoal
This is the most basic comparison of gunpowder. She had studied it inadvertently because she was so strange, and she remembered it in her heart. She didn't expect that she could still use it now.
Gunpowder is now called black gunpowder. It is made by mixing potassium nitrate, sulfur powder and charcoal powder in a certain proportion, 75% potassium nitrate, 10% sulfur, and 15% charcoal. When black gunpowder catches fire, the following chemicals occur.
Reaction: 2kno3+s+3c=====k2s+n2↑+3co2↑Oxygen released from potassium nitrate causes charcoal and sulfur to burn violently, instantly producing a large amount of heat, nitrogen, carbon dioxide and other gases. Due to the rapid expansion of the volume, the pressure
It grew violently, and an explosion occurred. It is estimated that about every 4 grams of black gunpowder burns, 280 liters of gas can be produced, and the volume can expand by nearly ten thousand times.
She rolled up her sleeves and began to study.
At this time, she must remain absolutely calm and careful. If something goes wrong, she will have to lose her life.
To be honest, if she hadn't wanted a stable life in the future and did not want to fight again, she would never have done such a dangerous thing.
She went to the mountains every day, stayed for most of the day, and when she came back, she was covered in dust.
"Si Ya, what's wrong with you?" Gu Shi couldn't help asking worriedly when she saw Qi You'er's face was gray again.
"Smashed," Qi Youer touched her face tiredly. Alas, I don't know how many times she failed. She almost had no time. Really, Ting Yu said that the blacksmith could ship the goods, but she
But I just touched a side here.
No, she has to work harder and work harder. She has once again demonstrated her unremitting spirit of hard work. She has become more courageous as she sets down. I don’t know how many days have passed, she went out cleanly this morning and returned in a dusty manner.
Every time Gu asked, he fell down.
Gu also worriedly found the doctor and asked him to see Qi You'er's legs to see if there was something wrong with her legs and why did she fall down every day these days.
The old doctor looked at the sky again and said a lot of words. Qi Youer kept nodding. She disagreed. She was tired and was taking a nap. Anyway, the old doctor could do anything, saying that she was bone.
It's okay to be loose, but this is a lot of medicine. Qi You'er is crying and needs to take medicine. Anyway, he can't kill anyone, but it's too bitter, and she can't ignore it. When she saw Gu's painting
She could only drink her crying look, and she cried better than her mother.
The weather was very good on this day, and everyone was thinking about going to the ground earlier so that they could do more work.
Then I heard a bang, and I felt like the earth was shaking.
"It's not good, the earth is moving," I don't know who shouted, and everyone ran out of their home in panic, but after waiting for a long time, they didn't see anyone moving any more.
Tinglan looked at the mountain strangely. He tilted his head, and the sound seemed to be coming from somewhere. He turned around and walked towards the other end of the mountain. He didn't know what Qi You'er was doing, why did he do it so big.
As soon as he arrived, he saw Qi Youer standing there again in a dusty face, but he smiled and looked stupid.
