The entrance and exit are really hidden corners. If you didn't firmly believe that the joint base had a backup plan, you would have thought it was a notch in the hull if you saw it in broad daylight.

It's only about one meter wide, and even the door is rusty.

Jiang Ning was so wicked that he first poured two barrels of sulfuric acid in, then sealed the door outside, and then tied two bombs to it.

As long as the people inside pushed the door, they would pull the fuse of the bomb, and then they would be blown to pieces.

The two of them walked around and didn't find any other entrances, so they walked towards the main entrance.

Considering the ether and sulfuric acid that had just been poured, Jiang Ning took out a gas mask and put it on.

The two looked at each other and resolutely stepped into the bombed door.

It was dark and cold inside, and the terrain kept going down. The bodies of base members and crocodiles could be seen everywhere.

With the help of night vision goggles, the two men entered slowly with weapons.

After walking for about half an hour, they began to see faint lights.

The red-eyed crocodile is extremely destructive, leaving blood everywhere and the base in a mess.

Huo Yishen noticed that there was a red light flashing in the hidden corner on the top of the corridor.

The base not only has an electrical system, but also has cameras installed.

Without hesitation, he raised his gun and smashed the camera, while using his eyes to remind Jiang Ning to pay attention.

I don’t know how deep the water is in the joint base, so don’t let the secrets of the space be exposed unless it is absolutely necessary.

The long passage leading to the bottom of the sea ended, and the view suddenly opened up. There were rows of "well"-shaped houses made of the same special materials, and the flickering lights were eerie and terrifying.

The underwater base was not only unexpectedly large, but also designed like a maze.

Unlike the blood and mess in the corridor, this place was very clean and tidy, even the door handles were the same, and there were no numbers.

The two did not separate, and whenever they found lights and cameras, they were all destroyed.

Huo Yishen tried to push the door, but several doors failed to open, and then the next door suddenly opened.

There was a foreigner standing in the room, staring at the two of them with wide eyes.

Jiang Ning was about to intervene, but the man fell down with a bang.

There was still a weak breath, probably poisoned.

Jiang Ning made up the knife, and then looked around the room.

The room was about ten square meters, empty and empty, with a ventilation duct on the top.

Huo Yi stared at the ventilation duct and found that it could be selectively closed.

This means that there may be many survivors in the base.

The maze was dead silent but there was no blood or chaos, which was enough to prove that the red-eyed crocodile had not broken in.

Jiang Ning looked down at the ground. There were traces of criss-crossing slides, and the same was true for the ceiling.

If she guessed correctly, these houses were mobile and could be combined infinitely.

She had a bad feeling.

Without saying a word, all the lights within the range were turned off.

A voice suddenly rang from the ceiling, "wee to the underground city." It was

a man's voice, low and magnetic and teasing.

Jiang Ning raised his gun without hesitation and blew up the loudspeaker.

There was a sudden movement behind him, and a room moved in to block the aisle.

The door of the room at the end of the corridor suddenly opened, and thick yellow smoke gushed out.

Poison gas!

The joint base was fighting back.

Wherever the yellow poisonous smoke went, the coated room corroded and changed color instantly.

Not only is it poisonous, but it is also extremely corrosive.

It is simply not something that ordinary protective clothing and masks can withstand.

Huo Yishen's face changed color, "Run!"

He pulled Jiang Ning and ran to the back.

However, the exit was blocked by the room, and no matter how hard they kicked, they couldn't kick it open.

In desperation, the two could only kick the rooms on both sides. They

were also as solid as rocks and could not be kicked open at all.

The yellow poisonous smoke was getting closer and closer. Huo Yishen made up his mind and pulled Jiang Ning towards the poisonous smoke...

Before the poisonous smoke came over, he opened the house where the body was just found and hid in.

The room was pitch black, and Jiang Ning quickly slipped into the space.

The poisonous gas was very strong and corrosive, so the two could only change their equipment and take out the best fully enclosed biochemical suits.

They knew that the joint base was not easy to break into, but they didn't expect it to be so difficult.

The two secretly broke into a cold sweat. This is not a joint base, it is clearly a biochemical base.

Fortunately, they stockpiled biochemical suits before the natural disaster, but it is hard to say whether they can withstand the poisonous gas attack.

Jiang Ning couldn't help but wonder, is this still the base where more than 10,000 people were destroyed by the Russian bear?

It seems that either the Russians are lying or the base has been upgraded.

The two sat down to rest, and Huo Yishen analyzed, "We blocked the ventilation duct, but they still dared to release poison gas, which shows that the foundation is layered on the seabed, and the ventilation of this layer cannot threaten them."

Jiang Ning was suspicious, "Are you saying that they have other ventilation systems?"

"Not necessarily ventilation systems, but oxygen production circulation."

They have warships and transport ships, and the living conditions there are not bad, but they chose to build an underwater base, which must be for safety and comfort considerations.

It is estimated that it is similar to China's national plan. They want to work hard to build a national base, but something went wrong during the period. This team has very few people. However, they picked up a lot of allies during the escape, and then recruited a lot of lackeys. Finally, they arrived in the Arctic and settled down and built a new base.

Judging from the number of ships, their number will not be small when they arrive.

Nearly 20,000 people were killed by the Russian bear. One reason is arrogance and underestimation of the enemy; the other is that it is very likely that the underwater base was not completely built at that time, and they were killed by surprise.

Now that the underwater base has been completely built, it is not easy to break it.

Whether it is easy or not, Jiang Ning has no way out. They are determined to make things difficult for him.

Now that people are already in the base, they can only bite the bullet and go to the end.

This is how it is to survive in the apocalypse. It's not that you endure or compromise, others will be willing to help you.

The two waited patiently for half an hour, put on their biochemical suits, opened the oxygen valve, confirmed each other's eyes and left.

Wearing biochemical suits, holding weapons becomes extremely clumsy.

The moment he flashed out of the space, Huo Yishen protected Jiang Ning in his arms.

He was afraid that there was danger outside, or that the poisonous gas would corrode the biochemical suit.

It was still the same room just now, the corpse on the ground was already a pool of rotten flesh, and the door was corroded with countless holes.

The corpse should have been corroded by the poisonous gas that penetrated through the holes.

Such a strong biochemical gas is creepy.

But when the two came out, the yellow poisonous gas had disappeared.

But Jiang Ning did not dare to take it lightly, and stared closely at his and Huo Yishen's biochemical suits. Fortunately, no changes occurred.

The biochemical suits he exchanged with Qin Chuan were very advanced, with a built-in sensor system, which would give an early warning in case of damage or leakage.

The two looked at each other, pushed open the door and walked in.

The corridor was pitch black, but many of the rooms that were closed before were already open. Rotting

corpses could be seen everywhere.

In other words, there were living people in many rooms.

Judging from their twisted bodies, they died very painfully.

Looking at these rotting corpses, Jiang Ning felt heavy-hearted and his scalp numbed.
