Bright Sword: Starting from the Improved Grenade

At night, everything was quiet. Li Yunlong and Zhang Dabiao stood at the entrance of the village, looking forward to it.

"Why hasn't the captain arrived yet? I'm freezing to death."

Zhang Dabiao rubbed his hands to relieve the coldness a little.

"What's the hurry? We'll be here soon."

Li Yunlong was calm and composed. Of course, it would be more convincing if we could ignore the thick cotton-padded jacket he was wearing.

"Then Captain, can you take off your cotton jacket and let me wear it? I'll return it to you when we go back later."

As he said that, Zhang Dabiao stretched out his hand and prepared to strip Li Yunlong's clothes.

"Hey, what do you want to do? Comrade Zhang Dabiao, please pay attention to discipline."

Li Yunlong hurriedly protected his cotton jacket.

"Hey, Captain, just let me wear it for a while, just for a while."

"Let go, or I'll hit you!"

Just as the two were arguing, Li Yunlong's eyes lit up: "Don't fucking take off my clothes, Brother Tianyang and the others are here."

"oh oh."

Zhang Dabiao obediently stopped what he was doing and just made a fuss. Did he really think he dared to take off Li Yunlong's cotton-padded jacket?

"How is it? Is the place ready?"

Zhao Tianyang, who was moving with the tank, asked Li Yunlong.

He had discussed with Li Yunlong a day ago that confidentiality measures should be taken for the tanks, so Li Yunlong led the Second Battalion to set out first, creating the illusion that all members of the New First Regiment were present.

The Third Battalion was responsible for secretly transporting tanks, and they marched at night and rested during the day.

"It's been prepared a long time ago. It's just east of Xingjiazhuang. It's a wasteland with Taihang Mountain at its back. I had people dig a cave there this afternoon. We can just pull the tank in later."

Li Yunlong pointed to the Taihang Mountains not far away and said.

Hearing this, Zhao Tianyang looked over and saw that the Taihang Mountains were looming in the darkness and nothing could be seen.

"Okay, stop looking and eat first. I prepared some white noodles."

During the day, after discussing the garrison matters with Old Man Xing, he spent a large sum of money to buy all the flour from Xingjiazhuang.

Prepare to give some nourishment to these brothers who have pulled the tanks all the way.

"alright."

Zhao Tianyang gave up observing. It was pitch dark and he couldn't see anything. He decided to wait until daytime.

After happily eating a bowl of white noodles, Zhao Tianyang and the soldiers from the third battalion lay down in the tent and began to rest.

Li Yunlong and the first battalion of people will take care of the rest of the matters, so they don't have to worry about them.

The next day, Zhao Tianyang got up early.

"I haven't slept so comfortably in a long time."

Facing the rising sun, Zhao Tianyang stretched himself lazily, feeling refreshed.

"Director."

Li Yuncai came in front of Zhao Tianyang, and the workers from the arsenal followed behind him.

There were a lot of things to do today, so they got up early and gathered together on their own initiative, saving Zhao Tianyang the trouble of calling people.

"Since you are here, I won't waste any more words. Our arsenal has just moved to Xingjiazhuang, and we have to start all over again."

"I wonder if you have the confidence to rebuild a bigger and better arsenal here."

"Have confidence."

Everyone looked relaxed. With the experience of the last trip to the small mountain village, they felt that this time it would be a piece of cake, no more than Zhang Fei eating bean sprouts.

"very good."

Zhao Tianyang smiled. He also felt that this time things would go much more smoothly.

.................

Xingjiazhuang has a superior geographical location and rich resources. The spring water from Taihang Mountains forms a long river, which saves Zhao Tianyang from spending time and effort digging wells.

Moreover, wells are not as useful as flowing water sources for arsenals.

"It just so happens that this place is surrounded by mountains and water, so we can build a new arsenal here."

After selecting a new site for the factory, Zhao Tianyang handed over the specific work to Li Yuncai.

He ran into the tent and started writing and drawing. The war was about to start, so he had to speed up and come up with more powerful weapons.

"Master Chang, you lead the team to build an earthen blast furnace first. Master Li, you lead the team to the mountain to see if there is a suitable place to build a sulfuric acid plant."

"Remember to bring your guns. There are many wild animals in the mountains. The rest of you, follow me to Xingjiazhuang to recruit workers."

As soon as Zhao Tianyang left, Li Yun immediately began to assign tasks to everyone. Soon everyone was divided into three teams and started to act.

After making TNT last time, Zhao Tianyang discovered that although TNT was good, it also had great limitations in its use.

Whether it is to make mines or explosives, detonators or other explosives are needed.

Therefore, the most urgent task is to either solve these two problems or develop digested glycerin. However, as a liquid high explosive, digested glycerin is not as safe as TNT.

"It seems that we have to deal with the detonators and ammonium nitrate first."

Considering the current poor production conditions in the arsenal, Zhao Tianyang decided to put safety first.

After two hours of writing and drawing, two design drawings successfully appeared in front of him.

"Okay, it's time to ask Lao Li for materials."

As he spoke, he picked up the blueprint and walked towards Xingjiazhuang, preparing to get some supplies from the logistics department for experiments.

"We'll arrange a sentry post here, and we'll stick to the old rules of one bright and one dark."

Zhao Tianyang found Li Yunlong on a hill outside Xingjiazhuang. He was leading his men to arrange the defense.

"Brother Tianyang, if you have any problem, just tell someone to tell me. You are sweating profusely after running."

As he spoke, Li Yunlong handed over the water bottle at his waist: "Come and have a drink of water."

"Tons, tons, tons..."

After taking two big gulps of wine, Zhao Tianyang wiped the sweat off his face and handed Li Yunlong the list of supplies that needed to be collected.

"Sign it."

Upon hearing this, Li Yunlong picked up the pen and signed his name without even looking at it.

"Well, don't doubt it. Although Li Yunlong is not well educated, he can definitely write his own name."

After signing, Zhao Tianyang picked up the material list and turned to leave: "I'm leaving first, you can take your time."

Looking at Zhao Tianyang leaving, Li Yunlong touched his head and then began to arrange defensive matters.

Detonators are divided into basic detonators, electric detonators, detonating detonators and electric detonators which only appeared in the 80s.

It is mainly composed of mercury fulminate (metallic mercury, dilute nitric acid, and ethanol as raw materials) and copper tubes.

What Zhao Tianyang was going to make was basic detonators.

After getting the materials he wanted from the logistics department, Zhao Tianyang returned to the tent.

This was the temporary camp of the arsenal. He first found a large iron spoon, put a small piece of silver in it, and then heated it.

After the silver melted, Zhao Tianyang found a beaker, added nitric acid into the beaker, and then added the melted silver into it.

Instantly, smoke rose up and emitted a pungent smell, which was the result of the two things reacting.

After the nitric acid and silver are completely fused, thunder silver liquid is generated.

Take another beaker and pour in ethanol, then pour in the thunder silver liquid. Soon the two begin to react and produce a lot of smoke.

After the reaction is completed, only some light gray precipitate is left in the beaker, which is silver fulminate.

Looking at the silver fulminate in the beaker, Zhao Tianyang thought for a moment and carefully poured out a little bit of it, then found a hammer and hit it hard.

With a "pop" sound, accompanied by some dust being raised, a satisfied smile appeared on Zhao Tianyang's face.

"It's successful. The next step is to put the silver fulminate into the paper tube."

(Because silver fulminate will undergo a substitution reaction with the copper tube and turn into highly sensitive fulminate copper, Zhao Tianyang replaced the copper tube with a paper tube here)"
