A magazine of 30,000 rounds, you call it Hanyang

As a result, the remaining Japanese soldier hiding behind the rock dared not move even more.

Zheng Kaixuan gestured to Wang Chengzhu.

Wang Chengzhu immediately aimed at the rock where the Japanese were hiding, and would shoot if they dared to show their heads.

Zheng Kaixuan held his breath and tiptoed towards the Japanese hiding place.

A moment later, Zheng Kaixuan reached the stone. He turned around and fired a shot, knocking the Japanese soldier to the ground before he could react.

Four devils, kill them all!

Wang Chengzhu also rushed over quickly and met up with Zheng Kaixuan.

Looking at the four Japanese corpses lying on the ground, Zheng Kaixuan was overjoyed.

Among these four Japanese soldiers, two were privates. The one who was shot in the head had shoulder straps that were different from the previous Japanese soldiers. It was made of red wool with a golden strip of cloth sewn in the middle.

This is a Japanese soldier with the rank of sergeant!

A sergeant is also a soldier, but he is taller than an ordinary soldier.

As for the last Japanese soldier who was shot down by Zheng Kaixuan, it surprised Zheng Kaixuan even more.

This bastard is actually a non-commissioned officer.

The epaulettes are made of red tweed with a golden strip of cloth sewn in the middle, with a five-pointed star on it.

This five-pointed star is fundamentally different from those of ordinary Japanese soldiers. The five-pointed stars of ordinary Japanese soldiers are embroidered with needle and thread, but this Japanese soldier's five-pointed star is made of brass.

This is a Japanese sergeant!

The rank of sergeant is similar to that of corporal in Western armies and is the lowest non-commissioned officer.

Generally, they can serve as team leaders. For example, these Japanese devils just now should be a rifle team.

The reason why this Japanese soldier was able to survive until the end was probably mainly because he was a non-commissioned officer, and the other Japanese soldiers did not dare to go ahead first.

Zheng Kaixuan suddenly felt excited.

Although the system's task this time is to only kill one Japanese sergeant, judging from the rules of the Hanyang-made mainline upgrade task, it is naturally better to eliminate a Japanese rank as high as possible.

[Ding, congratulations to the host, you have completed the main mission of killing the Japanese soldier and received a chance to modify the Hanyang rifle.]

[The magic modification accessories have been distributed to the backpack, please modify it yourself. 】

This time, what appeared in Zheng Kaixuan's backpack was also a magazine, four bullets, but the magazine was much larger and the bullet capacity was much larger.

Each magazine holds 60 rounds!

Zheng Kaixuan found a total of 200 bullets from the four Japanese soldiers in front of him. Together with the remaining ones he had seized before, it was enough to fill four magazines.

Zheng Kaixuan quickly filled a magazine and replaced it with a new one.

[Ding, congratulations to the host, you have completed the fourth level of the Hanyang Demon Modification. ]

[Ding, system main quest, continue to modify the Hanyang-made Type 88 rifle. The quest requires you to kill a Japanese corporal.]

And the system did not disappoint Zheng Kaixuan. The Japanese sergeant he had just killed still counted.

[Ding! Congratulations to the host, you have completed the mission of killing the Japanese corporal. The magic modified accessories have been distributed to the host's backpack.]

I opened the iron box backpack again, and this time there were quite a few accessories in the box.

A gun body, a fixed magazine, a firing pin for firing bullets, and a trigger.

There are also some small, very complex yet extremely delicate accessories.

Zheng Kaixuan's eyes suddenly lit up and sparkled!

That's the light of excitement!

As a civilian inventor and military industry enthusiast, who graduated from the Yunnan Army Academy's Department of Engineering Mechanics, how could he not see that these accessories are part of the configuration of a fully automatic rifle!

"Good boy, system, you are really good."

Zheng Kaixuan never thought that just by killing a Japanese sergeant, he would get the opportunity to modify a fully automatic rifle!

"Zhu Zi, help me keep watch."

Seeing that no Japanese soldiers were rushing towards him for the time being, Zheng Kaixuan called out to Wang Chengzhu and began to quickly disassemble the Hanyang-made Level 4 rifle in his hand.

"Kakakaka..."

His movements were as smooth as flowing water, extremely fast.

"Brother Kaixuan, we're at war, what the hell are you doing?..."

Wang Chengzhu muttered a few words, shook his head helplessly, sighed, and had to hold his gun and start standing guard for Zheng Kaixuan.

In fact, he knew very well that Zheng Kaixuan and he were the same type of people, and both of them were basically crazy.

Who in their right mind would rush into the enemy position alone during a war?

As for Zheng Kaixuan, he was simply obsessed with researching military weapons...

In no time, Zheng Kaixuan successfully assembled the Hanyang rifle with more sophisticated parts replaced.

The Hanyang-made fully automatic rifle suddenly appeared!

The newly modified Hanyang rifle is also equipped with a rate of fire switch function.

In other words, the shooting mode of this gun can be switched freely between semi-automatic and fully automatic.

The fully automatic rifle is naturally easy to use and has very strong firepower. With a fully automatic rifle in hand, Zheng Kaixuan can even suppress the firepower of an entire Japanese infantry platoon by himself.

The powerful firepower is the advantage of fully automatic, but also the disadvantage. It consumes ammunition too quickly! The consumption is huge!

Also, in continuous firing mode, the recoil will increase, resulting in a decrease in accuracy when shooting at enemy targets.

The biggest advantage of semi-automatic is low bullet consumption, high shooting accuracy and small recoil.

Switch between the two modes at will and roam the battlefield without any pressure!

[Ding, the Hanyang-made Level 5 Modification was successful! Congratulations to the host, you have obtained the Hanyang-made fully automatic rifle!]

[Ding, system main quest, continue to modify the Hanyang-made Type 88 rifle. The quest requires you to kill a Japanese sergeant.]

In the distance, more than 300 meters away from Zheng Kaixuan and Wang Chengzhu, a Japanese officer holding a telescope vaguely saw the figures of Zheng Kaixuan and Wang Chengzhu, and he immediately became furious.

"Baga! Baga! Why are these two Eighth Route Army soldiers here on our position? Machine gunners, kill them immediately! They're dead!"

The Japanese machine gun immediately turned its muzzle and fired at Zheng Kaixuan and Wang Chengzhu.

"hidden."

The two men bent down instantly, and bullets hit the rocks in front of them, causing gravel to fly and sparks to splash.

"Damn it, those damned Japs, what's so great about having a machine gun!"

Zheng Kaixuan suddenly became furious.

He picked up the Hanyang-made fully automatic rifle, walked around to the other end of the rock, quietly stuck his head out, pulled the safety with a sound of Kaba, and immediately opened fire at full power.

The bullets rained down like raindrops, pouring down towards the Japanese machine gunner at a speed as fast as a storm.

"Damn it, I'll show you how powerful your Eighth Route Army grandfather is."

"Da da da da da da da..."

"Da da da da da da da da..."
