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

While the other battalions were leading the miners to frantically eliminate the Japanese and puppet troops everywhere in the mine, Zheng Kaixuan was not idle either.

He was carrying out sabotage in the mining area with the soldiers of the Second Battalion and accompanied by Liu Daqiang.

Time is limited, and the Japanese soldiers near the mining area may arrive at any time, so he dare not waste any more time.

After all, this is the Japanese's rear area, and they cannot take away many heavy and bulky items.

The only option is to destroy it.

Liu Daqiang played a very important role at this moment.

If Liu Daqiang hadn't been there, even if the spearhead group had broken into the mining area, they wouldn't have known where to start sabotaging it.

But with Liu Daqiang here, things are completely different.

At this moment, Liu Daqiang was surrounded by a group of technicians who used to be engineers in the mine like him.

These people are the elites in the mine and know what to destroy in order to maximize the losses to the Japanese.

When you kill a snake, you have to hit it at its most vulnerable part, and the same applies to sabotage.

For example, the Sharp Knife Regiment discovered two large warehouses where the Japanese stored coal.

There are mountains of coal inside, at least hundreds of thousands of tons.

Not to mention the few people Zheng Kaixuan brought with him, even if the entire 129th Division was brought here, it might take ten days or half a month to move all of them away without any interference from the enemy.

In this situation where there is nothing that can be taken away, the only option is to destroy it!

We must not leave it to the devils.

If these things are not destroyed, they will eventually become resources for the Japanese and become bullets shot at the villagers.

"Old Liu, how long will it take to burn all this coal?"

Although Zheng Kaixuan was reluctant, he gritted his teeth and decided to destroy it.

"It's not difficult to destroy it. Just pour kerosene on it. As long as you pour kerosene on it and light it, even if a large number of Japanese troops can attack right now, they won't be able to put out the fire!"

Liu Daqiang is very professional.

"I know where I can find kerosene. Please follow me."

Soon, Zheng Kaixuan, the soldiers of the second battalion, and Liu Daqiang found a very hidden small warehouse.

Hundreds of barrels of kerosene are piled here.

With the help of the miners, hundreds of barrels of kerosene were quickly poured onto the coal pile one by one.

"burn!"

Zheng Kaixuan gritted his teeth and gave the order.

A match was lit and thrown onto the coals.

"boom!"

A raging fire immediately shot up into the sky, illuminating the entire night sky within several kilometers.

All the soldiers and miners who saw the flames rising into the sky felt extremely heartbroken.

This is our own resource!

However, everyone had a smile on their face.

We can burn our own resources and make a fire, as long as we don't leave them to those Japanese slaves!

"All those boilers have blown up. Without them, they can't make kerosene!"

Under the command of Liu Daqiang, the soldiers of the spearhead regiment threw triumph grenades into more than a dozen large boilers.

"Boom! Boom!"

With a loud rumbling sound, more than a dozen large boilers were blown up.

Falling apart and shattered!

"The chimney blew up!"

Zheng Kaixuan directly ordered Yang Wanli to use the Triumph mortar vehicle to bombard.

The towering chimneys soon collapsed and shattered to the ground under the bombardment of artillery shells.

"The big pool cannot be left either. It's used for washing coal."

Immediately afterwards, the soldiers of the second battalion blew up the wall of the large pool, and the water in the pool flowed all over the ground and spread everywhere.

"Destroy the windmill!"

"Iron bridge, blow it up!"

"Winch house, razed to the ground!"

With Liu Daqiang's reminder, the spearhead regiment achieved twice the result with half the effort, with precise strikes and explosions.

Soon most of the important production facilities in the mining area were destroyed.

Immediately afterwards, Liu Daqiang brought Zheng Kaixuan and others to the motor room.

"These machines are all new ones imported from abroad last year. They've all been sold cheaply to the Japanese."

"As long as we destroy it, the Japanese won't be able to buy it back even if they spend a lot of money."

Zheng Kaixuan took a look and couldn't help but exclaim in amazement.

Many of the machines in the motor room are made of fine steel and are very heavy.

The steel of many machines is even thicker than the armor of the Triumphal Chariot!

How to destroy such a thick steel plate?

Even bombing with artillery shells wouldn't necessarily be enough. What about piling up explosive packs? How much explosives would that take?

But with Liu Daqiang here, all problems are no longer problems.

"Pour oil on it and set it on fire."

A raging fire soon broke out.

However, the melting point of steel is extremely high, reaching over 1,500 degrees!

Although the machines in the computer room may not all be made of pure steel, it is impossible to melt them in this environment.

When the machines in the computer room were burned red by the fire, Liu Daqiang waved his hand.

“Water it!”

At this moment, the soldiers of the spearhead regiment who had been waiting outside with water pipes began to spray water at the machine.

"laugh--"

The fire was gradually extinguished, and streams of white smoke emerged from the machines. The steel machines, which had been expanded by the fire, shrank rapidly after being cooled, and then began to deform at a speed visible to the naked eye.

Zheng Kaixuan naturally understood the principle of thermal expansion and thermal contraction.

Every machine here is extremely precise, not even the slightest error can be tolerated. If this happens, the steel will warp and deform, which is equivalent to being completely scrapped!

"Captain Zheng, if this happens, all these machines will be useless."

"Good! Lao Liu, well done!"

Zheng Kaixuan gave Liu Daqiang a thumbs up.

Without delaying any longer, Zheng Kaixuan immediately organized everyone to evacuate the mining area quickly.

As many as seven or eight thousand miners, along with the Sharp Knife Regiment, left the mining area before the Japanese reinforcements arrived.

Zheng Kaixuan distributed all the food, supplies, and money seized from the enemy's bases, artillery towers, and warehouses to them, and gave them everything they could take away.

More than 3,000 puppet troops, Japanese infantry battalions, inspection teams, and gendarmerie were eliminated, and hundreds of boxes of grenades, more than 3,000 Type 38 rifles, and tens of thousands of bullets were seized. Zheng Kaixuan distributed all of them to the miners.

Although all the miners asked to follow the spearhead group, Zheng Kaixuan did not take them with him.

It’s not that Zheng Kaixuan doesn’t want to lead them, but there are too many people and the target is too big.

The Japanese army may form a siege at any time. Zheng Kaixuan and the spearhead regiment are the enemy's main targets. Taking them with them will only implicate them and may result in no one being able to escape, which will only cause them to sacrifice in vain.

Most of these miners are locals and are familiar with the terrain here.

If they disperse and walk separately, there will be basically no problem for them to escape.

After all the miners were dismissed, Zheng Kai turned around and looked at the mining area. He set up all three mortar tanks.

"Blow it up, blow it up hard!"

Another wave of fierce bombing turned the mining area upside down and the ground collapsed.

"Captain Zheng, great job! With this, the Japanese won't be able to resume production in this mining area for another two years."

Liu Daqiang applauded.

"withdraw!"

Before several Japanese troops surrounded the mining area, Zheng Kaixuan led 300 brave warriors of the Sharp Knife Regiment and successfully broke through the encirclement and headed southwest.

Target, Longquanyu!

Return to the group and return in triumph!

Of course, Zheng Kaixuan also knew that Longquanyu would definitely not be empty, and there would definitely be a big battle waiting for them.

However, this couldn't stop him at all.

In this battle in the mining area, his biggest gain was actually 3500 Japanese epaulettes.

According to rough statistics, there were about 4,000 Japanese devils and puppet troops in the mine.

However, most of them died under artillery fire, or from bombardments by light mortar vehicles operated by company and platoon-level officers of each battalion.

With these more than 3,000 epaulettes, the strength of the Spearhead Regiment can be taken to the next level.

No monsters or demons can stop them from returning home.

"System, synthesize equipment for me in batches!"
