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

Zheng Kaixuan was indeed well prepared.

The other seven level 13 drones were all carrying triumph grenades and explosive packs.

The reason why I chose to do these little tricks quietly in the past was mainly to collect these dozens of lieutenant colonel shoulder badges and was afraid of alerting the enemy.

Now that it's almost complete, there's nothing to worry about.

If they don't come out, I'll just blow up the house too! Blow these two bastards to death inside the house.

Anyway, it's just bombing two houses, and the explosives carried by these drones are more than enough.

"Boom boom boom boom..."

Dozens of triumph grenades and more than a dozen explosive packs were thrown down. With the loud explosions, the two houses were almost razed to the ground in an instant.

Flames shot up into the sky, illuminating the night sky.

A large number of Japanese soldiers and puppet troops were in chaos and rushed over with water to put out the fire.

[Ding, congratulations to the host for obtaining a Japanese lieutenant colonel's epaulette.]

[Ding, congratulations to the host, you have obtained a Japanese Colonel's epaulette.]

"Withdraw all drones."

Zheng Kaixuan immediately ordered all drones to return.

The predetermined goal has been achieved, enough epaulettes!

Not only is it enough, but I also got an extra colonel shoulder strap!

Zheng Kaixuan didn't hesitate and started to modify it.

"System, mass-modify and upgrade Triumph drones."

[Ding, congratulations to the host. Nine Japanese Lieutenant Colonel Epaulettes have been consumed to batch upgrade nine level 12 Triumph UAVs to level 13. Please check.]

So far, the Spearhead Regiment has three level 14 Triumph UAVs, and the remaining 27 have all been upgraded to level 13.

The thirteenth-level Triumph UAV has a range of fifty kilometers.

Of course, during the day, the battery life is theoretically unlimited.

As long as there is sufficient sunlight, the battery will be restored in a few minutes.

Insufficient power will only occur at night or on rainy days when the battery cannot be replenished in time.

The Triumph UAV Reconnaissance and Attack Company is divided into three platoons.

Each platoon has one Class 14 aircraft, and nine Class 13 aircraft are unmanned.

Within each row, each drone has a clear division of labor.

Each platoon has two level 13 drones responsible for information collection, early warning and other reconnaissance tasks.

Drones fly high, see far, and can move quickly and freely in the air. They can be said to be invincible winged scouts.

Even if the enemy is several kilometers away, the reconnaissance drone can detect it and issue an early warning in time.

Each row has four transport support aircraft, which are mainly responsible for the supply of weapons and ammunition.

The other four are responsible for combat, precision attacks and strikes.

Of course, this is just the coordination and division of labor when the drone reconnaissance company performs tasks independently.

When they go out with the main force, they can all perform reconnaissance missions, all perform strike missions, and even all perform battlefield supply missions. They can be used in any way you want.

After the drone formation was established, Zheng Kaixuan was not in a hurry.

If you want to launch a major counterattack, you must be fully prepared.

The Japanese had air superiority. In order to prevent the Japanese from using fighter planes to bomb the spearhead regiment during the counterattack, he took out the colonel's epaulettes in his hand.

"System, magically upgrade a Hanyang-made fully automatic rifle tank to level 14."

[Ding! Congratulations to the host, you have successfully modified the Hanyang-made fully automatic tank to level 14!]

A tier 14 Hanyang tank, equipped with an anti-aircraft machine gun.

With the addition of this anti-aircraft machine gun vehicle, Zheng Kaixuan now has two anti-aircraft machine guns.

The Hanyang anti-aircraft machine gun's powerful inventory of 3,000 high-explosive armor-piercing shells, coupled with its strong flexibility and maneuverability, can already pose a great threat to the Japanese fighter planes.

With it, Zheng Kaixuan felt more confident leading the large army out of the mountains.

Of course, this is only the current situation. Zheng Kaixuan believes that it won't be long before he will have more air defense weapons, turning the entire sky above Heiyunkou into a restricted zone for fighter jets.

[Ding, congratulations to the host, you have obtained the right to redeem new auxiliary equipment in the system mall. ]

At this moment, a prompt sounded in Zheng Kaixuan's mind.

He also didn't expect that upgrading the second anti-aircraft machine gun vehicle would bring him an unexpected surprise.

[Ding, congratulations to the host, you have obtained the right to exchange for a Triumph solar electric car. The exchange rate is as follows: one Japanese soldier's shoulder badge can be exchanged for one Triumph electric car, one Japanese non-commissioned officer's shoulder badge can be exchanged for two Triumph electric cars, and one Japanese lieutenant officer's shoulder badge can be exchanged for three Triumph electric cars...]

Oh my god, an electric car?

Even Zheng Kaixuan was surprised. No matter how he guessed before, he never thought that the auxiliary equipment provided by the system this time would be an electric car.

"Then, exchange one for me first and let me take a look."

It cannot be ridden in the mountains, but it can be used in the upcoming counterattack.

Zheng Kaixuan couldn't wait to use up an ordinary Japanese soldier's shoulder strap and prepare to see what this electric car of the system looked like.

[Ding, a Triumph electric car exchange has been successful. Please check it.]

With a flash of white light, a four-wheeled electric vehicle appeared in front of Zheng Kaixuan.

Although it is called a four-wheeled vehicle, it actually only has two main large wheels, and two palm-sized auxiliary wheels are installed on the lower sides of the back seat.

In this way, as long as the training wheels are lowered, no matter how the rider rides, the bike will basically remain balanced and will not fall over.

Of course, if you want to pursue speed, you can also put away the training wheels.

The Triumph solar electric car has a streamlined body and a bulletproof glass shaped like an arrow at the front.

It can block the fire from the Japanese 7.7mm heavy machine gun!

The wheels are crawler tires made of special lightweight steel! They can adapt to most terrains.

When you encounter danger, jump out of the car and hide on the side. This car is a bulletproof shield and a simple shelter!

The material of the car itself can absorb solar light, so it can be charged and stored at any time.

Charge for three minutes, get a full day of battery life!

This electric car can reach a maximum speed of 120 kilometers per hour, which is much faster than a war horse.

And it does not need to be fed or consume food.

On the battlefield, if you ride a warhorse against the enemy and the horse is shot or frightened, the rider is basically doomed.

But this electric car won’t do that, it can be built casually!

Zheng Kaixuan felt that it was a great deal, a really great deal, to be able to exchange one for an ordinary Japanese shoulder badge.

He could now imagine the scene of the soldiers of the spearhead regiment riding this electric bike, crisscrossing the battlefield, whizzing back and forth and defeating the Japanese army.

Even he himself was already a little impatient.

Two days later, everything in the spearhead group was ready. Zheng Kaixuan stepped onto the platform and waved his hand with high spirits.

"Let's go! It's time to destroy the devils!"
