This group of Japanese soldiers not only did a very thorough job in early warning, but also in defense.

Inside the winding tunnel forks, there were many makeshift shelters made of bulletproof steel plates.

Ammunition boxes, about half a person's height, were piled up in several corners.

It was completely filled with bullets, grenades, and hand grenades of various calibers.

Walk into the tunnel.

In addition to the infrared early warning instrument that Liu Kai successfully passed.

Remote-controlled bombs were also installed on several key supporting structures and underground.

Whether it's blowing up tunnels to eliminate invaders or blocking the way to buy time for evacuation, these are both very effective methods.

Moreover, the subway tunnels run through the city, and in many places, residential buildings are located above them.

If an explosion causes the ground to collapse, many people will die.

This was also one of the Japanese devils' backup plans.

They silently took the survivors on the ground hostage.

Even if their base location is exposed, the Chinese troops will be hesitant to act rashly due to fear of harming the enemy.

If the authorities choose to evacuate the survivors.

This was tantamount to telling the Japanese soldiers inside the tunnel that they had been exposed.

Just as Qin Luofei had said.

These people are not just ordinary people; they are elites!

Take a complete view of the situation.

Liu Kai was actually a little confused.

He originally thought that the "bandits" who kidnapped women and children, lured addicts into hard labor, and supplied drugs everywhere were these Japanese devils.

However, it now seems that this does not conform to the assumption.

The room was filled with only strong male soldiers; there were no women, children, or even a greyhound.

Let's leave that issue aside.

Logically, the best course of action now would be to notify the authorities and let them come up with a solution.

But just as Liu Kai had anticipated.

He was utterly annoyed by these beasts and felt incredibly frustrated.

Now, the perfect opportunity to take care of these odds and ends yourself is right in front of you.

He still wanted to take a gamble!

and.

The weapon racks and ammunition boxes inside are truly enviable.

Liu Kai decided to stop moving forward and remain where he was to think of a solution.

He didn't really care about the lives of the survivors above the tunnel.

Even so.

Use the lives of Chinese people to exchange for the lives of Japanese devils?

It's not worth it.

What he wanted was a perfect massacre with zero casualties on one side!

We must now devise a way to both prevent the bombs from destroying the tunnel and to wipe out these Japanese soldiers in one fell swoop.

Defusing the bomb is definitely not an option; it would trigger the alarm system.

It would be troublesome if these Japanese soldiers ran away at the slightest sound.

"A bomb...a remote-controlled bomb. Huh? Remote-controlled?!"

Liu Kai's eyes lit up.

Electromagnetic wave shield!

Each jammer has an effective range of 50 meters, and he has a total of 6 of them.

Although the bombs inside the tunnel were placed far apart, they were all on the entrance route where Liu Kai was currently located.

Full-range shielding can be achieved with just 3 units.

Liu Kai acted immediately upon hearing the word and got to work.

Return to the cave via the same route.

After all, subway tunnels are dug very deep, and the energy required to teleport directly to the surface would be too great.

Following the location from memory, we soon arrived directly above the underground "command post".

The disguised signal antenna was easily discovered.

This is the communication antenna that extends from that huge communication instrument to the ground.

Place the electromagnetic wave shield in place and start the countdown in 5 minutes.

Then it quickly returned to the burrow, moving silently like an agile cheetah.

soon.

Three electromagnetic wave shields were placed in sequence in the area to cover the bomb.

Activate the blocking!

The Japanese soldiers inside the tunnel remained completely unaware.

They had no idea that their escape route had been completely blocked.

After doing all this, Liu Kai breathed a long sigh of relief.

He didn't intend to charge in recklessly.

After all, there were too many people inside, so they formed a defensive network to watch over and help each other.

Although the exoskeleton could protect against bullets, the Japanese weapons were not inferior either.

It not only has heavy machine guns, heavy sniper rifles, and grenades, but also powerful weapons such as grenades and RPGs.

Such weapon configuration could also cause the tunnel to collapse.

Moreover, it is enough to pose a fatal threat to the exoskeleton.

Using spatial abilities to teleport and ambush one by one is extremely costly and the effect is not ideal.

Of course, Liu Kai had a plan.

The best way to attack a sealed tunnel is undoubtedly through a poison gas attack.

He certainly didn't have any poison gas.

But it contains crude oil!

A few days ago, while clearing a drilling platform, a blowout occurred, and a lot of liquid crude oil accumulated in the storage space.

All of them have a flash point of over 30 degrees Celsius.

I was struggling to deal with them at the time, but I never expected they could be used here.

Crude oil has a complex composition, and burning it will consume oxygen inside the tunnel.

It can also produce toxic gases such as carbon monoxide, sulfur dioxide, and nitrogen trioxide.

A large amount of toxic gas rushed in, and even the exhaust fan was ineffective!

Time passed second by second.

Liu Kai mentally counted down the seconds and acted quickly, taking out several huge camping tent cloths from his storage space.

They quickly sealed the opening leading to the outside world completely.

finally.

The ice shield has only 30 seconds left in its 5-minute countdown.

He suddenly stopped what he was doing and gave a sinister laugh.

"Hehe, let you experience firsthand the cruel methods you used back then!"

Take out a camping alcohol torch and light it.

The next instant, a large amount of dark, viscous liquid crude oil fell to the ground.

Under the influence of gravity, it continued to unfold, covering a very wide area.

Before the crude oil could solidify at low temperatures.
