Chen Xiaobei became excited when he saw it. The rocks pressing on the iron thunder were blown into dozens of pieces, and the cast iron was also broken into pieces of different sizes.
The largest piece of cast iron is half as big as my own palm, and the smaller one is naturally about the same size as powder.
Well, it seems that cast iron is still a suitable material.
The next thing left for Chen Xiaobei is the most important question, that is, how to solve the problem of ignition. Lighting it with a fire stick and throwing it out is safe, but there is no suddenness or concealment.
Therefore, in order to become a standard mine, this problem must be solved.
Chen Xiaobei returned home and began to design this device.
While I was drawing pictures at home, suddenly there was a sound of dogs barking outside, and Huang Ying and Shen Ziyan came back.
The three days of vacation flew by.
Tomorrow is the day when classes start, so the two of them came back early.
Cui Hongyu and the others chatted for a while in the yard. Huang Ying looked around and suddenly asked, "Hey, where is brother Xiaobei? How many fried fires has he done these days?"
Cui Hongyu pointed towards the room, "I don't know what I have been doing in the past few days in the room. I kept drawing pictures there."
When Huang Ying heard that she was interested, she jumped into the house and shouted loudly, "Brother Xiaobei, brother Xiaobei, what are you studying again?"
Seeing Huang Ying coming, Chen Xiaobei didn't hide anything, so he showed her some pictures he drew, "I want to research a device that can automatically ignite this fuse."
After hearing his words, a look of surprise flashed across Huang Ying's face.
"Light the fuse?"
Chen Xiaobei explained it to him with a cast iron shell he made. Huang Ying nodded, it was much faster than chiseling stone by yourself.
But he looked at the percussion ignition device drawn by Chen Xiaobei and shook his head.
"Brother Xiaobei, isn't this too much trouble? You have to make one for one use, and I don't know how many to blow up those people on the mountain."
Huang Ying's words reminded Chen Xiaobei. Thinking about it, in this era of underdeveloped technology, it would be difficult to make one by yourself.
Thinking of this, Chen Xiaobei drew another one by dividing five by three.
This is very simple and similar to the principle of striking a match.
Just pull it.
"There is another plan like this. Just pull it and you can light it, but I need a suitable material."
After hearing what he said, Huang Ying really laughed and said, "I can do this. The master made a special kind at that time. It is easier to use than Huozhezi. It can start a fire just by rubbing it."
After saying that, Huang Ying turned around and ran away. After a short time, she hurriedly came back with a small wooden box in her hand.
Huang Ying took out some dark brown medicinal powder from the small wooden box.
Huang Ying wet the medicinal powder with water, and then took out three small wooden sticks as long as her thumbs. The thickness of these small wooden sticks was similar to the matchsticks in her previous life.
After gluing the medicinal powder, Huang Ying took the small wooden stick and carefully approached the oil lamp.
While baking, raise your hand and carefully feel the temperature of the powder.
After about half a stick of incense, Huang Ying started laughing.
She handed a small wooden stick to Chen Xiaobei's hand, "Please wipe it on the table and try it."
When Chen Xiaobei saw it, he secretly admired it, "Isn't this just like a match?"
It seems that human wisdom is really infinite. In this era, these extraordinary people can create something similar to a match.
Chen Xiaobei used his slightly trembling hands to stroke gently, stabbing and scratching.
Seeing the fire light up, Chen Xiaobei became excited. He took Huang Ying's hand and said, "Huang Ying, how much of this do you have? I may need a lot."
Although Huang Ying looked carefree, she still looked a little surprised when her hand was suddenly grabbed by a man.
She groaned and her face turned red instantly.
Chen Xiaobei looked down and realized that he seemed to be a little rude, and hurriedly let go of his hand.
Outside the house, Shen Ziyan heard Huang Ying's cry and was about to rush into the house, but was stopped by Cui Hongyu.
"Don't worry, my husband doesn't know martial arts. Even ten of us can't beat Sister Huang Ying."
After hearing her words, Shen Ziyan turned around and thought about it, and then stopped.
In the room, Chen Xiaobei let go of Huang Ying's hand in a panic and said apologetically, "I'm sorry, I, I didn't mean it."
Huang Ying nodded and reached for the small wooden box on the table. "These are for you to use first. I still have them at home. I will bring you some next time."
After saying that, he stuffed the wooden box into Chen Xiaobei's hand, turned around and went out.
Well, Chen Xiao thought this matter would be over, but there was a lot of excitement outside the house.
When Cui Hongyu and Shen Ziyan saw Huang Ying coming out, they immediately surrounded her, and Shen Ziyan held her hand with concern.
"Sister Huang Ying, what happened to you just now?"
Huang Ying blushed again, "It's nothing, I was shocked just now."
Obviously this excuse cannot be believed by Shen Zi, Ziyan and Cui Hongyu, but it is no longer important, especially to Cui Hongyu, Huang Ying and Chen Xiaobei can do whatever they want in the house.
Seeing that the atmosphere was a little awkward, Huang Ying quickly said, "Okay, okay, Sister Ziyan, let's go back quickly."
When they all left, Cui Hongyu walked in with a smile on her face. Seeing that Chen Xiaobei was still experimenting, she stepped forward and gently pressed Chen Xiaobei's hand, "Husband, you and Sister Huang Ying were here just now. here?"
Chen Xiaobei thought Cui Hongyu had misunderstood, and quickly explained, "No, no, I didn't do anything, I just touched her accidentally."
I thought Cui Hongyu would be angry, but I didn't expect Cui Hongyu to smile happily, "Okay, okay, husband, I'll touch you more often in the future."
Chen Xiaobei understood instantly that he was worrying about marrying a second wife again.
"Kuyu, why are you trying so hard to marry me a second wife? Isn't it good for us to do this?"
Cui Hongyu shook her head, "No, I can't serve my husband all the time by myself. I feel bad!"
When Chen Xiaobei heard this, he chuckled, picked up Cui Hongyu by the waist, and was about to throw her on the bed, "Then serve me first tonight."
At this moment, Chen Xiaobei turned around and saw Chen Qiaoer standing silently at the door.
Alas, the critical moment.
Chen Xiaobei had no choice but to put Cui Hongyu down again, smiled and waved to Chen Qiaoer, "Okay, okay, go to bed quickly."
But Chen Qiaoer looked at Cui Hongyu and said seriously, "Sister-in-law should sleep with me today."
I.
Chen Xiaobei sighed helplessly, it seemed that marrying a second wife was really necessary.
While Cui Hongyu and Qiaoer went to rest, Chen Xiaobei improved several more matches.
Clamp the match between two slightly rough stone slabs. When the force is right, gently pull the match and it will catch fire.
Great, the problem of ignition has been solved. The mine has been officially manufactured successfully and can be tested tomorrow.
