Zheng Fang and Nie Guohai followed the secret passage to find a dark river, and there was a speedboat next to the dark river, which seemed to be the back hand prepared by the researchers here.

No, their backhand became Zheng Fang and Nie Guohai's 'backhand'.

"Let's go, there's a message from Tianxing, if we slow down, something might happen to them. ”

Nie Guohai said and pressed the button in his hand, and immediately, from the position of the secret passage, a series of explosions came.

When the shock wave of the explosion hit Zheng Fang and Nie Guohai, they had already left the dark river and came to the sea.

The explosions were all located at the support nodes of the research facility, and after a series of explosions, the entire research facility was completely covered by collapsed debris.

Everything here is destroyed, and even if you want to dig it out, you need to use heavy construction machinery to dig it for half a year.

This is China's territorial waters, and the island countries dare to do things that are quietly touched, and they dare not do blatant things.

......

"It's really thrilling, if it weren't for you two, I would have planted it. ”

On the other side, the third and fourth elders and Bu Tianxing also discovered research facilities on the island.

Like Zheng Fang's side, the research facility was heavily guarded, and they infiltrated by wearing enemy clothes.

Finally sneaked into the deeper position of the road, there were obviously a lot fewer people here, and Bu Tianxing breathed a sigh of relief.

"No, look there!"

The third child suddenly discovered something, and hid behind the rock and pointed in the direction of the depths of the cave.

When the fourth child and Bu Tianxing looked at it, they were all shocked.

Further on, both guards and researchers wore protective suits.

The protective clothing they wear is not a simple three-proof suit, but a fully enclosed type with its own oxygen backpack.

"Good boy, the protection is so tight, it seems that the things inside are amazing. ”

The third child looked at the fully enclosed protective clothing of those people and swallowed and spitted.

"The opposite side is so tightly guarded, it means that what they have developed is very dangerous, whether it is biological weapons or chemical weapons, they must be strictly sealed and will not be easily leaked. ”

"Protective clothing is more of an insurance policy, and it can significantly reduce the field of view. ”

The third child observed it and said.

"What are you going to do!"

Bu Tianxing listened to the words of the third child, and had a bad premonition in his heart.

"We gambled, we bet that what they developed was not leaked, and we took advantage of the narrow field of vision caused by their protective clothing and touched it. ”

"Under normal circumstances, this kind of thing will not be leaked, so the odds of winning the bet are quite large. ”

The fourth and third have cooperated for many years, and immediately understood what the third wanted to say.

"You two can't be serious, can you? ”

Bu Tianxing was a little worried.

He is not afraid, if he is alone, he will also make such a choice, for the sake of the task, Bu Tianxing will not back down.

However, the thought of coming into contact with such things as biological weapons and chemical weapons, even if they are isolated, makes me feel uncomfortable.

If you are not comfortable, you will not be at ease, and the task will still be completed.

Several people cautiously touched the depths of the research institute.

There are two infiltration masters, the third and the fourth, and those who have limited vision really haven't found a few people.

"That's it. ”

The three of them came to the door of a storage room, which was a cold storage room, which is usually used to store biological weapons.

The third and fourth children silently killed the first place at the door, and in the storage room, they found a specially protected sealed glass tube.

The liquid in the glass tube had an eerie dark blue color.

The glass tube is in a separate isolation box with two robotic arms.

The third child packed the glass tube in a metal box through a robotic arm, and then opened the sealed box.

Bu Tianxing knew that the main force to break through for a while was the third and fourth children, and took the initiative to put the box on himself.

For safety, the box is placed directly on the chest.

"It feels...... It's hard to put into words. ”

Thinking that the box attached to his chest was a very dangerous biological weapon, Bu Tianxing's mood was very complicated.

"The guards are dead!

At this moment, the body at the door was found, and the nearby guards immediately arrived.

The third and fourth companies rushed out of the storage room, and before the other party was in place, they used the automatic rifle in their hands to suppress the fire, Bu Tianxing took the gun, solved the approaching few people, and the three of them immediately ran outside the cave.

There are no secret passages here, so it's easier said than done if you want to go out directly!

This cave doesn't even have a fork in the road, and if you want to get out, you have to collide directly with all the defenders.

"It's hard to get out. ”

Bu Tianxing thought about the density of troops in the cave for a moment, and frowned.

"I brought a single soldier cloud burst bomb, and we rely on this to kill it!"

The third child went up from his back and got down a big thick tube.

Individual cloud burst bombs, which can be carried by individual soldiers, are disposable, and thrown away after fighting.

It has a radius of 50 meters on flat ground.

Because of the special explosion principle, its shock wave and the consumption of oxygen, it is an absolute killer of such a confined space.

A single cloudburst bomb can deplete the oxygen of the entire cave, and the shockwave generated can destroy everything that stands in its way!

"Third child, if this thing is out, we won't die first. ”

Bu Tianxing can know the power of this thing.

"If you don't fight, you will definitely die, and if we can survive if we fight, we will have a chance to rush out!"

"After a while, the oxygen in the hole will be exhausted after the explosion. ”

The fourth child had already removed three sets of oxygen backpacks from the corpses on the ground.

The three of them could already hear the footsteps getting closer and closer, and without hesitation, the fourth and third children hid behind a rock, and the third pulled the trigger in the direction outside the cave.

As the thick cloud burst out of the chamber, the third child immediately ran to the location of the rock.

"Bang!"

A small explosion sounded, and the cloudburst bomb exploded in the middle of the cave, and the liquid fuel inside quickly turned into mist under the action of high explosives, expanding the entire cave.

Suddenly, these weapons scattered in the cave exploded as if they had been ignited!

The air wave and high temperature swept through the entire cave, and the unsuspecting island defenders in the cave were all wiped out in an instant, and even if there were those who survived, in the oxygen-deficient environment, only suffocation awaited him.

Because of the obstruction of the rocks, the three of them were not directly impacted, and they would not suffocate if they had prepared oxygen backpacks.

However, the third child didn't have time to hide behind the rocks, and his back was burned under the action of the high temperature and air waves.

"Let's go!"

The fourth and Bu Tianxing ran out with the injured third with one in their arms.

Those who wore protective clothing in the back, because the distance was relatively far, and the three-proof clothing on their bodies had the effect of flame retardant and heat insulation, and they did not suffer too many injuries, but under the direct impact of the shock wave, they also needed to slow down for a while.

This was enough time for them to rush out of the cave.

"Whew!"

A few people had just left the cave, and even one person put on a ventilator, and took a big breath of the cool air outside the cave.
