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

Not only Zhang Dabiao and the 300 brothers who were left behind by the independent regiment, but also Li Yunlong, Ding Wei, Xing Zhiguo, and even Yamamoto Ikki on the other side of the stone bridge and Wang Sipi, the former commander of the 8th Mixed Brigade of the puppet army, as well as all the puppet soldiers who were crossing the river, and everyone around Wanjia Town, all stopped what they were doing, opened their mouths in surprise and looked up at the sky.

The scene above the sky is really too shocking.

The sky is covered with dense drones!

They are all very small drones. Although these drones are small in size, there are many of them, as many as several thousand!

To the extent that the sunlight in the sky near the river was obscured by the shadows of these drones.

In Liuzhuang, Zheng Kaixuan sat calmly beside the tea table, picked up a cup of tea and took a sip leisurely.

This is the killer move he prepared to deal with the 8th Mixed Brigade of the puppet army!

Zheng Kaixuan has been researching large-scale group attack weapons with great destructive power to deal with the Japanese and puppet troops.

In fact, whether it is the Triumph mortar vehicle or the anti-aircraft machine gun, they all count, but the reputation of the Spearhead Regiment is too great now.

For example, in the battle of Wanjia Town this time, as long as the Sharp Knife Group brought a large number of main battle weapons to participate in the battle, the enemy would definitely flee without a fight and would not have the courage to fight with the Sharp Knife Group at all.

Zheng Kaixuan hopes to develop some weapons that are powerful, convenient, fast, and able to strike unexpectedly.

So he placed his hopes on the Japanese major general's shoulder strap.

The shoulder straps of the Japanese major general were captured last year, but he has never been willing to use them.

Up to now, the only senior shoulder straps he had were one major general shoulder strap and three colonel shoulder straps.

One of them was a colonel shoulder strap that was obtained from killing Matsui Shunsho near the prisoner-of-war camp not long ago.

After much thought, he set his sights on the Level 14 Triumph anti-aircraft gun.

Apart from anything else, the power of this anti-aircraft gun is simply too strong.

A single artillery shell can explode into thousands of powerful shrapnel, making it a true airplane killer.

If this anti-aircraft gun is placed flat, it is no exaggeration to say that one shell can directly make one or two Japanese infantry squadrons lose their combat effectiveness.

Zheng Kaixuan couldn't imagine what this weapon would become after being upgraded.

If it is upgraded to level 15, and this Triumph anti-aircraft gun has ten barrels, wouldn't it be able to kill an entire Japanese infantry battalion with one shot?

If this is true, then to deal with the 8th Mixed Brigade this time, he only needs to deploy a level 15 Triumph anti-aircraft gun and carry a large amount of ammunition.

Zheng Kaixuan gritted his teeth and took out the major general's epaulettes.

"System, use this Japanese Major General's epaulette to upgrade my Level 14 Triumph Anti-Aircraft Artillery Tank."

[Ding! Congratulations to the host, the Triumph Anti-Aircraft Artillery Tank has been successfully upgraded. The current tank level is level 15.]

The level 15 Triumph anti-aircraft gun vehicle did not become the ten-barreled vehicle that Zheng Kaixuan expected.

Although the ten mortar barrels are still retained at the front of the vehicle body, the anti-aircraft gun still has only one barrel.

This made Zheng Kaixuan very disappointed.

The difference between the level 15 Triumph Anti-aircraft Gun and the level 14 is that it has a new radar detection system!

A large screen was installed inside the car.

Some antennas that can emit electromagnetic waves have also been installed around the tank.

After these high-frequency electromagnetic waves are emitted, when they encounter objects blocking them, part of them will be reflected back and received by the antenna.

Based on the characteristics of the returned electromagnetic waves, the radar system will analyze the shape, size, moving speed and precise distance from the tank of the object in front or at high altitude that reflects the electromagnetic waves.

After calculation by the radar system, the shapes of these objects will be presented graphically on the display screen inside the car.

With electromagnetic wave radar detection, it means that the Triumph anti-aircraft artillery vehicle has become a modern advanced equipment.

From now on, this level 15 tank can be controlled at will, and it can hit whatever it points at, with an accuracy of within half a meter!

Although this level 15 tank did not become the powerful one with ten gun barrels that Zheng Kaixuan had imagined, the onboard radar system was also very practical.

In fact, Zheng Kaixuan received some surprises when using this major general's epaulettes.

For example, in terms of obtaining epaulettes, in the past only officers above the squad leader level under Zheng Kaixuan could obtain epaulettes after they eliminated the Japanese invaders, but this time, it is finally open to soldiers.

This means that no matter who among all the soldiers in the regiment eliminates the Japanese and puppet troops, Zheng Kaixuan can obtain the Japanese shoulder badges.

Another surprise is that all weapons and equipment that have been modified in the past have opened up the exchange system!

In the past, before modifying a Hanyang rifle, you first had to have a Hanyang rifle as raw material.

Before you can modify a Triumph pistol, you must first have a Triumph pistol to modify it.

Including modified drones, you must first have a camera as raw material before you can carry out the modification.

This once caused Zheng Kaixuan a lot of trouble, and he once searched all over the world for old Hanyang rifles and cameras.

But sometimes the more you need something, the harder it is to find it.

Now, it is no longer necessary, the system has enabled redemption permissions.

As long as it is a type of weapon that has been modified once before, you only need to consume an ordinary Japanese shoulder badge to exchange it for a level one weapon equipment.

For example, the Hanyang rifle can be exchanged for one by consuming one epaulette, and it is already in the first-level modified state with a magazine capacity of 10 rounds.

For example, for a drone, you only need to consume one shoulder badge to exchange for a level one drone.

The unlocked permissions this time made Zheng Kaixuan ecstatic.

At the same time, his eyes suddenly lit up.

He felt that he had found a way to inflict large-scale casualties on the Japanese and puppet troops.

That is, win by quantity, attack in groups!

This tactic, also known as the honeycomb tactic, is absolutely amazing when it is actually implemented.

"System, exchange 3000 epaulettes for 3000 Level Triumph UAVs."

Since the battle of the prisoner-of-war camp, Zheng Kaixuan has a total of 5000 Japanese epaulettes in his hands, excluding the epaulettes that were consumed and the epaulettes that were harvested.

This time, he directly consumed three thousand ordinary Japanese epaulettes.

After exchanging for 3000 first-level small drones, Zheng Kaixuan consumed another 1000 Japanese epaulettes and exchanged for more than Triumph grenades!

The first-level Triumph UAV didn't actually have a bomb-dropping function, but that didn't bother Zheng Kaixuan at all.

As a folk inventor, he has strong hands-on ability. This is not the first time that he has made secondary modifications to weapons that have been modified by the system.

For example, he easily modified a level 13 or 14 drone into a manned flight. He also assembled a captured Type 1 anti-aircraft machine gun onto a tank and improved the ammunition supply method.

This time, Zheng Kaixuan led the robotics experts of the weapons support team to change the detonation method of the Triumph grenade to an impact explosion.

And they were fixed to these small drones with wire.

Each small drone is equipped with three to four Triumph grenades as big as cantaloupe melons.

When three thousand small Triumph drones, all equipped with bombs, flew over the Eighth Mixed Brigade of the puppet army, the puppet soldiers were scared to death on the spot.
