"Get out of here, it's poisonous..."

Qin Fei reminded the people around him.

Biogas is combustible.

In order to prevent gas explosions, Qin Fei and others also deliberately extinguished the torches in their hands and switched to flashlights for lighting.

The poison gas mine in the mangrove forest of the Ark was poisonous, and Qin Fei naturally knew this for a long time.

In the game, the player controls a character who enters the gas mine and will continue to lose blood due to the gas in the cave.

But the actual situation here is a little different from the game. The poison gas in this cave does not do as much damage to people as in the game.

This level of poisonous gas can be resisted with a homemade mask and some adsorbents.

After everyone retreated to a position where there was no poisonous gas, Qin Fei took out two gauze bandages from his backpack.

He retrieved some charcoal, cotton, sawdust, and lime from his backpack, and wrapped them around the two gauze bandages.

These common items have a strong adsorption effect, or have a certain filtration effect.

Fortunately, Qin Fei likes to put all kinds of materials he encounters into his backpack and put them in his backpack.

It is precisely this habit that allows him to get so many different kinds of adsorbents out at one time in such a short period of time.

After wrapping the adsorbent, Qin Fei wrapped the gauze around his face.

The adsorbent present in gauze can effectively filter and adsorb toxic substances in the air.

In this way, the damage caused by the poisonous gas to Qin Fei was greatly reduced.

Others immediately followed suit, using some items in their backpacks with an adsorption effect to make simple gas masks.

With the gas masks in hand, everyone was unimpeded all the way for the rest of the way, and soon came to the innermost level of the cave.

This is the room where the immunity artifact is placed.

Outside the artifact room, there were about a dozen orange-red giant eggs stacked up. The giant egg is also wrapped in countless white cobwebs.

Each of the giant eggs here is about the size of an adult.

Qin Fei observed carefully for a while.

He found that the giant eggs seemed to be in a constant process of contracting and expanding.... It's like... A beating heart.

These eggs.... It's all alive!

Qin Fei remembered that in the poison gas mine cave in the game, there were also these giant eggs.

However, these giant eggs in the game only appear as background screens.

Players will not be able to interact with them or destroy the eggs.

But it's a different story here.

Now, when Qin Fei was in the scene and saw these giant eggs, he really felt the sense of fear that would appear in the heart of human beings when facing unknown things.

What kind of creature can lay such a large egg.....

Also frightened by these giant eggs were Qin Fei's teammates.

Qin Fei and the three of them did not speak very tacitly.

They cautiously walked around the vicinity of the giant eggs.

Although Qin Fei didn't know if the noise would wake up these giant eggs, the fear in their hearts made them subconsciously keep quiet when they passed by.

The room where the immunity artifact is stored is also an extremely narrow passage.

It is wide enough for one person only.

Qin Fei and the others walked into the artifact room.

At the end of the room, there is an immunity artifact that glows red on the outside.

From a distance, the artifact resembles an oval-shaped egg, and some dark red lines can be seen on its surface.

These dark red lines are like blood vessels on an egg.

The shape of the whole artifact is very weird.

Qin Fei reached out and took off the immune artifact in front of him and put it in his backpack.

[Immunity of the Ancient Artifact: Peaceful state of mind, inviolable to all poisons. 】

......

'Click~! ’

At the moment when Qin Fei took away the immune artifact, there was a sudden sound similar to the cracking of an eggshell outside.

"There's a situation outside!"

Qin Fei secretly said in his heart that something was wrong.

Listening to this sound, it's a bit like those giant eggs outside bursting....

Could it be that while taking away the immune artifact, he also triggered a mechanism in the cave, which caused the rupture of these giant eggs?

Qin Fei glanced at Xie Nanai and Caesar.

After exchanging glances, the three of them came to the entrance of the artifact room with the shotgun in their arms.

Qin Fei looked out.

Outside the artifact room, the giant eggs placed on the ground had all burst open.

From these giant eggs, more than a dozen giant spiders with a height of nearly two meters came out.

Qin Fei recognized it at a glance....

The appearance of these spiders is very similar to the shape of the ultimate creature in the ark, the broodmother spider!

Or rather, these giant spiders are a miniature version of the broodmother!

If Qin Fei's guess was correct, these dozen eggs should have been left by the brooding spider. And the big spiders that hatch from these giant eggs should be the juveniles of the broodmother spiders....

The only difference between these spiders and adult brood mothers, other than their size, is that these juvenile spiders do not have eyes.

As soon as these giant spiders emerged from their egg shells, countless small spiders the size of eggs crawled out of their tails.

A giant spider can give birth to dozens of small spiders at a time.

In this way, there are hundreds of small spiders on the ground at this moment.

Seeing this scene, the three of Qin Fei, as well as the dire wolf and the devil frog beside them, were all forced back into the artifact room.

"Ignite the fire!"

In a hurry, Xie Nanai suddenly proposed.

"No, the hole is full of methane, and the ignition will definitely explode..."

Qin Fei immediately vetoed Xie Nanai's suggestion.

In such an environment where biogas is very dense, if an open flame suddenly appears, the biogas will burn instantaneously, and there is a risk of gas explosion.

At that time, Qin Fei didn't know if these spiders would die or not, but the three of them should be dead.

And because of the existence of these biogases, Qin Fei and the others didn't even dare to use guns at will.

Firearms have the same potential to ignite these biogases.

The giant spiders outside the artifact room, due to their size, were forced to stop when they crawled to the entrance of the artifact room.

With their size, they couldn't even get into the narrow entrance to the artifact room.

However, at this time, the little spiders born from those giant spiders crawled in from the entrance of the room.

The baby spiders produced by the broodmother spider should be the size of a cat or a dog.

However, the broodmother of these juveniles is nowhere near as large as they were at maturity, resulting in the small spiders they give birth to are also very small.

Therefore, although these little spiders looked disgusting, they posed no threat to Qin Fei and the others.

One foot on it can be trampled to death.

Qin Fei and the three of them were completely relieved when they saw that the big spiders outside couldn't come in, and these little spiders on the ground had no combat power.

The fear in everyone's hearts has also decreased a little.

Of course, being stuck in the artifact room like this by those giant spiders is definitely not a solution.

Not to mention that Qin Fei and the others have limited mission time, so they can't be spent all the time. The poisonous gas in this cave alone can kill them over time.

No matter how good a gas mask is, it certainly can't completely filter 100% toxic substances.

What's more, Qin Fei and the others are still wearing homemade simple masks.

Every time they breathe, some of the toxic substances in the air inevitably get into their bodies over time. The more toxic substances they inhale into their bodies, the more they will be....

It would be very unfavorable for Qin Fei and the others to drag it out like this.

What to do?

"Hey, these big spiders are scattered!"

Xie Nanai said suddenly.

Caesar rolled his eyes: "What's the use of that, it's not like we can't get out...."

Qin Fei looked outside the room.

At some point, the big spiders had scattered around the hole.
