Poor family mother and son

Chapter 549 Improvement
"Yeah, I failed, so I won't play anymore!" Chu Qing coped with it and took back the igniter, but thought in his heart: This is more than half of the success!
After returning to the house, Chu Qing studied the igniter again, but the delay was not enough. In addition, making it with iron sheets was very laborious and time consuming.

She asked Hou Ze to wait another day, even if she started to do it now, plus the whole day tomorrow, she wouldn't be able to do much.

Finally she thought of the reed pipe, which was strong enough to hold the spring.

When I think of reeds, I also think of bamboo.

Last time, Chu Qing transported a large amount of bamboo to the north to have materials for making bamboo, so he picked out a few that were as thick as the wrist.

Bamboo is used as the shell of the bomb, and the reed pipe is used as the igniter. It should be fine.

These materials are easy to saw, file and drill.

Now the main thing is to find a way to add a slow-burning material to the back of the igniter. If it can burn with a little spark, it can't burn too fast. It must be delayed for a few seconds.

If charcoal powder is used, it is too slow, and it must be gunpowder.

So how can it be flammable and delay time?

In the end, after much deliberation, I had to use the method of my ancestors, Nianzi.

Twister is much easier to make. Mix the gunpowder with some water to make a paste, soak the rubbed paper rope, and after soaking thoroughly, take out the paper rope and spread it on the table to dry.

It takes time for this thing to dry out. Chu Qing just drank a little wine at night, and when he was excited, he simply cut reed tubes and bamboo to make igniters and grenade shells.

Each igniter uses three reed pipes, the shortest one is used as a connecting pipe, a hole of a suitable size is drilled, two longer pieces are inserted on it, and the two ends are plugged.

The bamboo tube is cut into an oval shape or kept in its original shape, leaving a good opening to measure the thickness of the igniter, and the other end has a bamboo knot, which is very useful.

It was almost dawn before Chu Qing managed to doze off.

When I woke up when I heard the knock on the door, it was almost past time.

On the left side of the face, deep marks were left by the folds of the clothes, and the two locks of white hair on the temples were also messed up, sticking to the face half inside and outside half like spider silk.

"Oh my God!" Huang Rong couldn't move while holding the food, and exclaimed, "You're crazy! You haven't slept all night, what are you doing?!"

Chu Qing brushed her temples, and took the breakfast from Huang Rong: "Hey, I made a little firecracker, and you will ask Zhuo Yao to come find me later."

Zhuo Yao took the team to morning practice, and before he came back, Chu Qing finished eating in twos and started to assemble again.

First try the twister with an igniter, it can be ignited, and it burns for about five seconds, remember the length.

Cut the dried twisters according to the predetermined length, put them into the reed tube, and then install them into the goose-egg-shaped bamboo tube.

Ten of the earliest single-barrel igniters were made, without twisters inside, which were used for smoke bombs, but a small hole was made with nitrous sugar and filled with a little gunpowder.

This time, I still assembled ten smoke bombs and ten grenades.

The cylindrical bamboo tubes are smoke bombs, and the oval-shaped ones are grenades.

All assembled, Zhuo Yao came back, Chu Qing handed him another "smoke bomb", and said, "Try this time, can you achieve what Xiaobao said?"

Seeing Chu Qing pull out the safety pin last night, Zhuo Yao knew it when he saw the pull ring, and knew that Chu Qing could only be a "squib", and he didn't let go when he pulled the pull ring.

Chu Qing knocked it off: "Why don't you choke to death!"

Although the poison is not dead, the taste is sweet and choking, but there is nitrogen or nitrogen dioxide, which is either suffocating gas or irritating gas. Do you want the respiratory tract?

While speaking, gray smoke filled the air, and Zhuo Yao asked, "Have you put chili noodles?"

Chu Qing: "..."

The guards arranged by Zhuo Yao to stand guard on the roofs, trees, walls and other corners made gestures and made fun of the guards who were choking on the downwind side.

Mu Nianci was drying the books for Chu Qing, and a lot of ashes floated in. When he looked up, he saw thick smoke rising from Chu Qing's studio. He became anxious and shouted, "Hurry up, put out the fire! Put out the fire!" "

On the one hand, he ran towards Chu Qing in a panic, fearing that something might happen to Chu Qing.

Chu Qing was running to grab the choked fool who didn't know how to avoid him: "Don't run away, are you stupid!", and saw Mu Nianci running towards him, and then a figure jumped past her.

I couldn't see people clearly through the smoke, I only heard someone shouting from the guards: "Stop!"

The guard that Chu Qing was pulling immediately stood in front of Chu Qing.

"How are you?" The man had already jumped up to him, looking at Chu Qing through the guards, it was Wei Chengyi.

Hey, it was a false alarm.

Chu Qing asked, "Why are you here?"

Because he was going back the next day, Hou Ze went to live with Wei Chengyi last night. Wei Chengyi went to the director's office in the morning and came back after ordering mao. He wanted to buy some food for Hou Ze on the road.

Hou Ze was worried about Chuqing's progress, and had been anxious to come over to take a look, wanting to play with bombs, but Wei Chengyi was afraid that it would be too early to disturb Chuqing's rest, so he delayed coming here until now.

Unexpectedly, when he entered the courtyard, he heard Mu Nianci's shout, and then saw her running from Chu Qing's courtyard, Wei Chengyi reacted a little faster than Hou Ze, and arrived first.

Hou Ze also arrived at his heels: "Yo ho! Are you done?"

"The smoke bomb Xiaobao wants," Chu Qing replied, and immediately dismissed Zhuo Yao: "Bring me the firecracker you found yesterday."

You can't let these few touch each other, or the house will be blown up by them!

Because Chu Qing said yesterday that the "bomb" was specially made for Xiao Bao, Wei Chengyi speculated that Chu Qing sent Zhuo Yao away because he didn't want them to know, so he immediately stopped Hou Ze and stopped him from speaking.

Chu Qing saw it, but didn't explain it. She didn't really want to keep the bomb from Zhuo Yao, it was because Zhuo Yao had too many thoughts, and Chu Qing was afraid that he would play gunpowder with those guards.

Try not to let them do these things by hand, otherwise, if something happens, whoever is missing will feel sad.

Another selfishness is that Zhuo Yao likes Xiaobao so much, Chu Qing doesn't want Zhuo Yao to know that Xiaobao has become less "obedient" now, he should be disappointed.

Sometimes it's interesting to think about it, Xiaobao fell in love with Zhuo Yao at the first sight, and Zhuo Yao also fell in love with Xiaobao at the first sight, I hope it's not Yuelao blindly pulling red lines, it's good for them to separate.

After Zhuo Yao brought back the bought firecrackers, Chu Qing counted a few, the noise was not too loud, and Hou Ze didn't even look directly at them.

Also, people who have thrown bombs, can they still care about firecrackers?

Chu Qing dismantled all the firecrackers, collected the gunpowder, packed it in the bamboo tube of the smoke bomb just now, and led everyone to the open space in the small garden.

It's a bit more open here, only those iron bar fitness machines.

Insert a twister, then cover the bamboo tube, Zhuo Yao went to light it.

"Bang!" The sound was loud, but it wasn't as good as yesterday's bomb. Clearly observing the height of the smoke rising into the sky, um, it was indeed not pure enough.

Chu Qing probably used less than two taels of gunpowder yesterday, what is the concept of two taels?

It is about the weight of a teacup of water, which can be replaced with compacted gunpowder, which is only two-thirds of a teacup.

Just now, it was clear that the gunpowder in the firecrackers put into the bamboo tube was about two taels, and it was well pressed, but the smoke that rose was not half as high as yesterday.

Really can not.

That is to say, there are few foreign enemies, and gunpowder has little effect in the military.

Of course, the lack of iron ore is also a shortcoming.

However, if there is no gunpowder bonus in a fight with the country of Voss, I am afraid it will be hard to guarantee the big announcement.
