Bright Sword: Starting from the Improved Grenade

Outside the arsenal, on a newly cleared lot, Zhao Tianyang, Li Yunlong and others hid behind a low wall built with sandbags.

One hundred meters in front of them was a small wooden box containing a black powder grenade. There was also a long fuse attached to the box that extended into Zhao Tianyang's hand.

"Brother Tianyang, you are too cautious. Why go through so much trouble? If it were me, I would just hold it in my hand, light it on fire and throw it away. That would be it."

Li Yunlong looked at the fuse in Zhao Tianyang's hand with a bit of disapproval.

"Captain Li, what you said is wrong."

Zhao Tianyang's expression was serious, and even his tone became heavier unconsciously: "Weapons experiments have always been a very serious matter. If you are not careful, people will die."

"It's okay if someone dies. After all, everyone is willing to sacrifice themselves for the revolution. But it's a crime to delay the production of weapons."

"You don't want everyone to be unable to use good weapons and equipment, and have to fight the enemy with swords and spears, right?"

"this.........."

Li Yunlong felt a little embarrassed by what he said, and immediately looked at the people around him and spoke loudly.

"You all heard it, right? From now on, when you are testing weapons, you must listen to Brother Tianyang. No one is allowed to be careless. If anyone is careless, I will punish him."

"understood."

"Don't worry, Captain. We will definitely listen to the factory director."

Everyone responded quickly.

"Hey, brother Tianyang, look, we can get started now."

After getting the response, Li Yunlong immediately urged with a smile.

Zhao Tianyang nodded and lit the fuse with a match. With a "hiss", the orange-red flame quickly moved towards the wooden box and disappeared inside the box. The next moment, with a "bang", the wooden box was blown into pieces.

“Ohhhh… Success!”

"Great."

"Hahahaha, great job, brother Tianyang."

Li Yunlong patted Zhao Tianyang's shoulder excitedly.

Unlike everyone else who was excited, Zhao Tianyang was not very happy. Instead, he frowned.

The killing range of general grenades is between 7 and 15 meters, while the killing range of China's own grenades is between 4 and 6 meters.

The black powder grenades they make now have an even smaller killing range, only about 4 meters.

"What are you thinking, brother Tianyang? Aren't you happy that the grenade was successful?"

Li Yunlong asked casually when he saw Zhao Tianyang frowning.

"I am happy, but the power is a little weak."

"Small?"

Li Yunlong was surprised and said, "It's OK. At least it can kill people when it explodes. You don't know that our border areas used to make grenades, which only made a noise. Sometimes, even throwing grenades at the feet of the enemy didn't kill anyone."

"That's right, this is just the beginning."

"Let's go and see the damage."

As he said that, Li Yunlong took the lead and walked towards the explosion point not far away.

"One, two, three, four...six. Only six fragments are a bit too few."

When he arrived at the explosion point, Zhao Tianyang immediately counted the grenade fragments and found that they were completely different from what he expected.

Generally speaking, 15 grenade fragments are considered acceptable, and theirs is far short of that.

Is it still a problem with the grenade or the poor quality of the projectile?

But aren’t grenade shells all made of steel or cast iron? How come their fragments can do so much damage, but mine doesn’t?

It was still a problem of technology. Zhao Tianyang pounded his hands. He thought of the history when our army also faced this problem. Later, our ancestors worked tirelessly and successfully realized the "stainless steel stewing technology".

This technology can turn white cast iron into artillery shell blanks, soften them by annealing, and turn them into shell skins that can be cut and processed. The same technology can also be used on grenades to enhance their lethality.

However, in order to master the "stainless steel annealing technology", Li Yunlong must get some "zinc", otherwise everything will be in vain.

"What are you thinking about? You're looking sad."

Li Yunlong held a wooden board inlaid with broken pieces and looked at Zhao Tianyang who was in deep thought.

"Nothing, I just feel the power is still a little weak."

Zhao Tianyang was thinking about what was needed for the "Stainless Steel Stewing Technology" and replied casually.

"Oh, I thought it was something else."

Li Yunlong criticized with a serious face: "Brother Tianyang, I wonder why you always aim too high. I think this is good enough."

"This power is enough to kill a Japanese soldier. We must be down-to-earth in everything. We must first do well what is in front of us before we can consider what is behind."

"Oh, yes."

Zhao Tianyang looked at Li Yunlong expressionlessly and said, "I just thought of a way to increase the power of grenades. The conditions are very simple. Since you said so, let's fix the grenade in front of us first."

As he said this, he walked towards the sandbag wall, ready to continue the experiment.

“Ah… no.”

Li Yunlong quickly followed him: "Hey, brother Tianyang, I was just joking, tell me what the solution is."

"It's late, let's finish this one first."

"Please don't. I beg you, bro."

No matter what Li Yunlong said, Zhao Tianyang just ignored him and started to concentrate on experimenting with black powder grenades. He also prepared two grenades with added sugar to see how powerful they were.

Li Yunlong was right when he said that one should not be too ambitious. If one wants to master the "tin annealing technology", one must have a lot of "zinc".

With the current conditions of the New 1st Regiment, don't even think about it. It would be better to give Li Yunlong a few hundred grenades and let him use these grenades to start his own business, and then do other things after he has the capital.

Seeing that Zhao Tianyang refused to tell him no matter what he said, Li Yunlong could only put aside his curiosity and start observing the grenade experiment.

No matter what, let’s hug the grenade in front of us first.

After experiments, the black powder grenade was a great success, and the two white sugar version grenades that were specially made for the experiment were so powerful that it exceeded Zhao Tianyang's expectations.

It almost reached the power of a high explosive grenade, which made Li Yunlong very greedy. He said on the spot that he would go to the Japanese warehouse to steal several tons of sugar, make them all into grenades, and blow up the damn Japs.

"Okay, don't think about those things. This experiment was successful."

Zhao Tianyang interrupted Li Yunlong's fantasy: "I calculated that a black powder grenade has a charge of 50 grams. With our stock of black powder, we can probably make grenades."

"Really."

Li Yunlong was so excited that he almost jumped up. You know, Li Yunlong only used 3,600 grenades to fight the Yamazaki Battalion. If he had 5,000 grenades, he would be so excited.

"Don't be too happy too soon. We don't have enough iron to produce so many grenades. According to my estimate, we can only produce 2,000 at most."

"Enough is enough."

Li Yunlong waved his hand nonchalantly: "Don't give me more. As long as you have a thousand grenades, I promise to bring you enough steel to use up the remaining black powder."

"So confident?"

Zhao Tianyang said in surprise.

"Hehe, I'm not as good as you at making weapons, but when it comes to fighting, I've never been afraid of anyone."

Li Yunlong patted his chest, looking extremely proud. At this moment, even if the brigade commander was standing in front of him, he would dare to say a few words.

"Okay, send me some people. I can produce 2,000 grenades for you in five days at most. However, because we don't have red phosphorus, we can't just pull the trigger and throw the grenades."

Li Yunlong frowned when he heard this. This was a bit troublesome.

"But it doesn't matter. I know how to make a tinderbox. You can each have one, and it won't be a problem to light the fire."

"Hey, brother Tianyang, I have to say something to you. Why do you breathe so hard when you speak? You made me worry for nothing."
