Bright Sword: Starting from the Improved Grenade

Early the next morning, Li Yunlong brought Zhang Dabiao to the arsenal. He received news that the arsenal had successfully produced several small cannons.

Looking at Zhao Tianyang and others who were digging holes with shovels, Zhang Dabiao was a little curious.

"Captain Zhao's trench is not well dug. Not only is it crooked, but it's also so deep that people can't even show their heads out from inside."

"Haha, Captain Zhang, you don't know that this is not a trench for fighting. It is used to test the power of weapons. If it is dug too shallow, it will be dangerous."

Li Yunlong was about to speak when Zhao Tianyang, who had finished his work, came over and explained.

"Brother Tianyang, you just said you built a small steel cannon, but the weapon is there, why don't you take it out and show it to us!"

Li Yunlong was a little impatient, even though he had obtained a lot of grenade launchers when he robbed the Japanese transport vehicles last time.

But that thing doesn't have matching grenades or other heavy grenade launchers, so you can use it as little as possible. When you ambushes, you should use it as little as possible.

Now that they can make it themselves, he will also provide artillery coverage for the Japanese in the future.

"No problem, Uncle Li, hurry up and don't keep our angel investors waiting for too long."

Zhao Tianyang hurriedly shouted to Li Yuncai who was getting weapons in the warehouse.

You know, Li Yunlong put a lot of effort into this arsenal.

Sometimes, with just one word from Zhao Tianyang, Li Yunlong would put on civilian clothes, take Zhang Dabiao with him, and bravely enter the Japanese county town.

"I'm coming."

Li Yuncai responded, and the next moment he came out with several workers, carrying several grenade launchers and several boxes of ammunition.

"It seems a little different from the Japanese grenade launcher?"

Although he didn't understand what an angel investor was, Li Yunlong's attention was now completely attracted by the grenade launcher in Li Yuncai's hand.

"There's nothing we can do. After all, the quality of the steel is not up to standard." Zhao Tianyang spread his hands helplessly.

"So we increased the length of the barrel from 260 mm in Japanese to 400 mm, increased the thickness of the barrel wall accordingly, and changed the barrel from rifled to smoothbore."

"Then the power and range won't be affected, right?"

Li Yunlong was a little worried. The grenade launcher was so different from the Japanese one. It might be just a showpiece that looked good but was not practical.

"Haha, don't worry, although the difference is a bit big, with a little modification, it not only makes up for the gap, but is also slightly better than the Japanese grenade launcher!"

Zhao Tianyang pointed to the parts at the tail of the grenade launcher: "The increased length ensures the shooting distance and accuracy, and the caliber remains at 50 mm, which ensures the power of the grenade."

"At the same time, the vent hole at the bottom of the barrel can also change the chamber pressure inside the barrel, so that we can manually adjust the initial velocity and range of the grenade."

"As for the firing mechanism of the grenade launcher, it is even more ingenious, using a firing mechanism similar to the firing mechanism on a submachine gun."

"Use a handle to pull the firing pin back. The handle is rotated to a certain angle and stuck in a slot. Turn the handle back and suddenly let go, and the firing pin will rebound and fire."

"Just like firing a gun, 'bang' the grenade will be launched."

As he spoke, Zhao Tianyang also made a shooting gesture.

"Well, not bad, not bad."

Li Yunlong nodded repeatedly as he listened. Suddenly, he saw a worker taking out a streamlined grenade from an ammunition box and asked curiously.

"Why does this grenade look like a mortar, and even has a tail fin?"

"That's because our grenade launcher doesn't have rifling and can't stabilize its trajectory by rotation, so we can only change the shape of the grenade to make it stable on its own."

As soon as Zhao Tianyang finished explaining, Li Yuncai walked over and asked with a smile.

"Report, Commander, Factory Director, the grenade launcher is ready, shall we start the experiment?"

Zhao Tianyang glanced at Li Yunlong and signaled him, the regiment commander, to speak.

Li Yunlong adjusted his military cap and said excitedly, "Begin the experiment."

"Yes."

Li Yuncai saluted and walked back.

"There's a big pit 300 meters ahead of the target. Fire."

A worker pointed his thumb forward and pulled the trigger. With a "bang", a grenade was launched and landed 400 meters away.

"Why didn't it explode?"

Zhang Dabiao asked blankly.

"No explosives."

Zhao Tianyang looked ahead with a calm expression: "Now we are testing the shooting distance and accuracy of the grenade launcher. There is no need to waste explosives."

"I see."

Zhang Dabiao and Li Yunlong nodded, and the workers in front also readjusted the data and loaded another training bullet.

"Report, loading is complete."

"Ah."

Li Yuncai nodded: "There is a big pit 300 meters ahead, second test fire."

As soon as he finished speaking, the worker immediately pulled the trigger and a grenade was fired, landing at a position 350 meters away.

Zhao Tianyang was a little embarrassed: "The shooting of this grenade launcher mainly depends on the experience of the operator, and our workers are not skilled enough."

"Hahaha, that's easy."

Li Yunlong waved his hand and said, "Zhang Dabiao, go get Zhuzi for me."

"Yes."

A moment later, a sturdy man ran over.

"Captain, are you looking for me?"

Zhuzi saluted and asked.

"Well, go try out our newly developed grenade launcher."

Li Yunlong pointed to the grenade launcher placed not far away and said.

"Okay, just wait and see."

As an artilleryman, he had already seen the grenade launcher which was larger than the Japanese one. When he heard that he was asked to try it, he immediately ran over excitedly.

"Oh, that's some good stuff."

Zhuzi rubbed the barrel with his hand, as gently as if he was touching a woman's hand: "Brother, how do you use this thing?"

"Hey, do you see this part? Just do this, this, and this."

The worker also breathed a sigh of relief. He had made two mistakes in a row in front of the team leader and the factory director, and the pressure was enormous.

Now someone has replaced him and quickly explained to Zhuzi how to operate the grenade launcher.

"Understood, understood."

I can only say that he is worthy of being the artillery king of the New 1st Regiment. After just two simple operations, he immediately understood how to use this grenade launcher.

He immediately picked up a grenade and put it in, then looked at Li Yuncai beside him.

"Big pit 300 meters ahead, third test launch."

"Bang" a grenade was fired from the muzzle, flew high into the sky, and accurately fell into a 300-meter pit.

"I hit it, I hit it."

"Great! I thought there was a problem with the accuracy of the grenade launcher we designed."

"Okay, well done!"

Li Yunlong couldn't help but pat Zhao Tianyang on the shoulder to express his excitement.

"Don't get excited, it's not over yet."

Zhao Tianyang winked at Li Yuncai, indicating that he should continue the experiment.

"Big pit 350 meters ahead, fire."

"boom."

"Big pit 400 meters ahead, fire."

"boom."

"Big pit 500 meters ahead, fire."

"boom."

Following Li Yuncai's command, one grenade after another fell accurately into the large pit that had been dug in advance under the operation of Zhuzi.

"Big pit 600 meters ahead, fire."

Hearing this order, Zhao Tianyang became nervous. This distance was the maximum distance of the grenade launcher they made, and he didn't know if he could hit the target.

"boom."

The grenade deviated from its trajectory, and although it was shot to 600 meters, it did not hit the big pit.

"Missed."

Zhao Tianyang shook his head regretfully.

"It's okay. That distance is a matter of luck."

Li Yunlong thought it through clearly. Generally speaking, the effective range of a grenade launcher is within 300 meters.

Now that Zhuzi can guarantee to hit all 500 meters, it is a miracle in itself, and the rest cannot be forced.

"If I get more familiar with it, I should be able to win."

Zhuzi also touched the grenade launcher with regret. This grenade launcher was much better than the Japanese ones.

"Okay, let's load up."

Zhao Tianyang calmed himself down and gave instructions to Li Yuncai.

Soon, a grenade that was specially painted red was carefully taken out and handed to Zhuzi.

"Be careful, this thing is much more powerful than the Japanese grenade."

Without Li Yuncai's reminder, Zhuzi knew that there must be a lot of explosives inside the shells, which were a circle larger than the Japanese grenades.

"Big pit 300 meters ahead, fire."

"boom--"

The violent explosion caused a lot of dark soil to be thrown up from the big pit that Li Yuncai and his men had dug.

"Wow, this power."

Li Yunlong was overjoyed. With his rich military experience, he could tell that the power of this grenade was almost twice that of the Japanese grenades.

"Hahaha, just wait and see, little devil. Your grandpa will give you a big one soon."
