This group of people really has strong mental fortitude.

Even after witnessing such a horrific scene, they quickly recovered after a brief moment of mental blankness.

It immediately started shouting and pulled the warning switch next to it.

Then they quickly retreated deeper into the tunnel, grabbed the gas mask, and hurriedly put it on their heads.

In an instant, alarms blared and red lights flashed throughout the tunnel.

The smoke and toxic fumes were traveling too fast.

It's much faster than a human running!

Despite receiving warnings, many Japanese soldiers inside were still unaware of what had happened.

The muscular man who looked like a commander didn't care that the communication had been cut off.

They thought it was an enemy invasion.

They quickly grabbed their weapons and crouched behind cover, ready for battle.

Sudden.

Two people rushed in through the tunnel entrance.

Wearing a gas mask, he shouted in broken English, "Poison gas! Poison gas!"

Everyone who heard the word "poison gas" paled in shock.

However, before they could react, a torrent of black smoke had already arrived.

In an instant.

The already dim lighting was completely enveloped, allowing no light to penetrate.

The entire tunnel was pitch black.

Some Japanese soldiers quickly put on their gas masks, temporarily escaping death.

However, the sudden drop in oxygen levels still made them feel suffocated.

My brain started to feel slightly oxygen-deprived; I felt dizzy and couldn't muster any energy.

Even worse off were the Japanese soldiers who didn't put on gas masks immediately.

In the panic, I unconsciously breathed rapidly and inadvertently inhaled a few mouthfuls of black smoke.

It was these few puffs of black smoke that caused them chest tightness and nasal pain.

He clutched his throat in pain and collapsed to his knees.

He vomited white foam while his body was convulsing.

Although he did not die quickly, he had lost most of his mobility.

The muscular commander demonstrated the expected level of skill.

He firmly believed that this must be an enemy invasion, not an accidental pipe fire.

Because they had inspected the entire tunnel.

It is absolutely impossible for so much toxic smoke to appear out of thin air.

He didn't have time to think about why he was exposed; saving his life was the priority right now.

They quickly organized the remaining 20-odd people to retreat and disperse behind various bunkers.

Four machine gunners lay down in front to provide covering fire.

Two men, armed with heavy thermal imaging anti-materiel sniper rifles, hid further away, ready to kill with a single shot at any moment.

Five other people were carrying RPG rocket launchers on their shoulders.

This person held the remote control himself.

If things really come to that, just blow up the tunnel and escape with the team through the backup passage.

Unfortunately, he didn't know that those remote-controlled bombs were completely useless.

All of these tactical arrangements were observed by Liu Kai, who was being held accountable.

He didn't waste a moment.

When they see someone fall to the ground, they act immediately.

They were now standing in thick black smoke, having reached the last straight section of the passage where they could get a perfect shot.

Although the black smoke ahead was blocked by the huge exhaust fan, the intrusion speed slowed down.

However, the temperature of the black smoke was still very high.

The two men with thermal imaging sniper rifles could only see a screen full of white light; there wasn't a single person in sight.

Similarly, thermal imaging of exoskeletons is completely ineffective.

However, with the full scan enabled, Liu Kai didn't need his eyes at all.

Next, it's time for the massacre!

Because the Japanese soldiers retreated in a hurry, they left behind two ammunition boxes that were half a person tall.

Liu Kai waved his hand and took out several flashbangs from inside, a wicked smile playing on his lips.

The Japanese soldiers were highly focused and ready to fight at any moment.

But the enemy did not show up.

Suddenly, two spinning lumps of iron flew out from the thick smoke.

All the Japanese soldiers were startled, their pupils dilating suddenly.

They recognized the lump of iron.

Flashbang!

The next moment, everything went white before my eyes, and I heard a loud bang.

The shock made everyone dizzy.

These people are indeed experienced in combat.

The machine gunners were even more clear-headed; they knew that in this situation, the only option was to unleash a barrage of fire.

Use the dense barrage to slow down the enemy's advance and buy time for the team members to regain their sight and hearing.

He decisively pulled the trigger.

The piercing "clattering" sound instantly echoed inside the tunnel.

Bullets flew through the air, hurtling into the thick smoke.

Liu Kai also moved.

Relying on the exoskeleton's robust ballistic protection, they disregarded the small-caliber machine gun bullets and charged forward recklessly.

Sparks from bullets flashed all over his body.

They leaped out of the thick smoke at a speed far exceeding that of normal humans.

The exoskeleton smart glasses restore imaging functionality, and aiming assistance is activated.

He dodged the dense barrage of bullets with a sidestep, and two pistols appeared out of thin air in his hand.

"Bang bang bang..."

He wielded two guns simultaneously.

Every bullet precisely avoided the cover of the bulletproof vest and helmet.

They shot the Japanese soldiers directly into their faces, killing them instantly.

Even though the flashbangs caused most of the Japanese soldiers to lose their hearing.

Unfortunately, the sound of the gunshot was still too loud.

These experienced Japanese soldiers could clearly tell that the gunshots were not from their own comrades.

They all raised their guns and fired blindly at the spot where Liu Kai had fired.

"Thump! Thump!"

Two slightly muffled whooshing sounds came from the air.

Liu Kai, who had originally intended to withstand the bullets, immediately abandoned that plan.

Because that's the sound of a grenade being fired!

Concentrate your mind and teleport in another direction.

The next moment, two violent explosions suddenly occurred where he had been standing.
