"Yeah, I failed, I won't play anymore!" Chu Qing responded to the ignition device and took back the ignition device, but thought to himself: This is more than half the success!

After returning to the house, Chu Qing studied this igniter again, and the delay was not enough. In addition, making iron sheets was very laborious, not only time, but also time.

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

Finally, she thought of the reed tube, which was hard enough to hold the spring.

Thinking of reeds and bamboo.

Last time, in order to make a copy of the materials in the north, Chu Qing brought a large number of bamboos and went to choose a few that were thick with wrists. When he saw that it was already dry enough.

Bamboo is used as bomb shells and reed tubes are used as igniters, which should be OK.

It is easy to drill holes by sawing, filing, and drilling.

Now we mainly find a way to add a slow-fire material to the back of the igniter. We must burn it if we can get a little spark, but we can't burn it too fast. We must delay it for a few seconds.

If you use charcoal powder, it will be too slow and it will still be gunpowder.

So how can it be flammable and delay time?

Finally, after thinking about it, I had to use the method of my ancestors to twist the seeds.

The twister is much easier to make. Make some water into a paste of gunpowder and soak the rubbed paper rope. After soaking it thoroughly, Chu Qing took out the paper rope and spread it on the table to dry it.

It takes time to dry this thing. Chu Qing drank the wine in the evening and was excited, so he simply cut the reed tubes and bamboo to make igniters and grenade shells.

Each igniter uses three-section reed tubes, the shortest one is used as the connecting tube, drill holes of appropriate size, insert two pieces of longer ones on top, and then plug the two ends.

The bamboo tube is cut into a goose egg shape and maintaining a prototype. It measures the thickness of the igniter and leaves a good mouth. There are bamboo joints on the other end, which is very useful.

It was almost dawn that Chu Qing could only take a nap.

When I woke up by the knock on the door, Chen Shi was almost passing.

The left face was covered with deep marks from the folds of the clothes, and the two strands of white hair on the temples were rubbed in a mess, like spider silk, half inside and half on the face.

"My God!" Huang Rong couldn't move even with her food, and exclaimed: "You are crazy! If you don't sleep all night, what have you been tormenting?!"

Chu Qing closed his hair and took the breakfast handed over by Huang Rong: "Hehe, I made some firecrackers, and you will ask Zhuo Yao to come to me later."

Zhuo Yao took the team to practice morning. Before he came back, Chu Qing finished the meal in three and started assembly work again.

First try the twister with an igniter, it can be lit and burned to about five seconds, remember the length.

Cut the dried twists at a predetermined length, enter the reed tube, and then install them into the goose egg-shaped bamboo tube.

There were ten single-tube igniters in the earliest single-tube igniters, and they did not put twisters inside. This was for smoke screen bombs, and they just made a small hole in the salt sugar and filled it with a little gunpowder.

This time, we will assemble ten smokescreen bombs and ten grenades.

The cylindrical bamboo tube is a smokescreen, and the goose egg-shaped grenade is a grenade.

After they were assembled, Zhuo Yao also came back. Chu Qing handed him a "smoke screen" and said, "This time I try it, can I achieve what Xiaobao said?"

I saw Chu Qing pulling out the insurance sales last night. Zhuo Yao understood as soon as he saw the pulling ring. He also knew that Chu Qing could only be a "squid" and did not let go if he pulled the pulling ring off.

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

Although it is toxic and tastes sweet and choking, there is nitrogen or nitrogen dioxide, either asphyxiating gas or irritating gas. Do you still need it if the respiratory tract is?

As he spoke, gray smoke filled his mouth. Zhuo Yao asked: "Do you put pepper noodles?"

Chu Qing: "..."

The guards arranged by Zhuo Yao to watch the roof, trees, walls, etc., were more gestured and made fun of the guards who were choking in the downwind.

Mu Nianci was posting a book to Chu Qing, but a lot of dust floated. When she looked up, she saw thick smoke coming from Chu Qing’s studio. She became anxious and shouted, “Hurry up, put out the fire! Put out the fire!”

While running towards Chu Qing in a panic, he was afraid that Chu Qing would have any good intentions.

Chu Qingzheng ran to grab the stupid boy who was choked and didn't know how to avoid it: "Isn't you stupid?" Then he saw Mu Nianci running towards him, and then a figure jumped past her.

I couldn't see people clearly through the smoke, and I could only hear someone in the guard shouting: "Stop!"

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

"How are you?" The man had already rushed to the front and looked at Chu Qing through the guard. It was Wei Chengyi.

Oh, a false alarm.

Chu Qing asked, "Why are you here?"

Because he was going back the next day, Hou Ze went to Wei Chengyi to live in last night. Wei Chengyi came back after ordering Mao in the morning and wanted to buy Hou Ze some food for the road.

Hou Ze was worried about Chu Qing's progress and was anxious to come over to take a look. He wanted to play with the bomb. Wei Chengyi was afraid that it would disturb Chu Qing's rest too early, so he dragged it until now.

Unexpectedly, when he entered the yard, he heard Mu Nianci's shouts, and then he saw her running from Chu Qing's yard toward this side, Wei Chengyi's reaction was a little faster than Hou Ze and arrived first.

Hou Ze's heels and feet also arrived: "Oh! Are you ready?"

"Xiaobao wanted the smokescreen," Chu Qing replied, immediately sending Zhuo Yao away: "Give me a look at the firecracker you found yesterday."

You can't let these people meet together, otherwise the house would be blown away by them!

Because Chu Qing said yesterday that the "bomb" was specially made for Xiaobao, Wei Chengyi speculated that Chu Qing sent Zhuo Yao to him because he didn't want them to know, so he immediately stopped Hou Ze and refused to let him speak again.

Chu Qing saw it, but she didn't explain. She really wanted to keep it a secret about Zhuo Yao's hiding bombs, because Zhuo Yao had too many thoughts, and Chu Qing was afraid that he would take the guards to play with gunpowder.

Try not to let them do these things, otherwise Chu Qing will feel sad if something happens.

There is also a selfish intention, that is, Zhuo Yao likes Xiaobao so much, Chu Qing doesn't want Zhuo Yao to know that Xiaobao is becoming less "behaved" now, and he should be disappointed.

Sometimes it’s interesting to think about it. Xiaobao takes a look at Zhuo Yao at a glance. Zhuo Yao also takes a look at Xiaobao at a glance. I hope it’s not because of the Yue Lao’s blind connection. It’s good that they are apart.

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

Yes, can those who have thrown bombs still care about firecrackers?

Chu Qing dismantled all the firecrackers, collected the gunpowder together, stuffed them with the bamboo tube of the smokescreen just now, and took everyone to the open space in the small garden.

It's a little empty, with only those iron bar fitness machines.

Insert a twister, cover the bamboo tube lid, and Zhuo Yao went over and ignite it.

"Bang!" The sound was loud, but it was not as good as the bomb yesterday. Chu Qing observed the height of the smoke that took off. Well, it was indeed not purity.

Chu Qing used less than two taels of gunpowder yesterday. What does two taels mean?

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

Just now, Chu Qing put the gunpowder in the firecrackers into the bamboo tube, which was about two taels, and it was pressed down, but the smoke rising was less than half the height of yesterday.

Really not possible.

That is, the foreign enemy is rare, and gunpowder has almost no military achievements.

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

However, if we fight with Vos, without the bonus of gunpowder, it may be difficult for Daxuan to protect it.
