The fire wall continued to burn, and the oxygen in the air began to become thinner again.

Under the thin air and the thick smoke churned, the Phantom Spider's movement began to slow down, and the self-destructing spiders in the flight began to fall one by one.

In the smoke, Chen Xiao, who saw this scene vaguely, slowly opened the corners of his mouth.

This is the result he needs now. All retreats have been closed and the space for combat has been compressed.

This is obviously more beneficial to the Phantom Spider, and the back path has been cut off.

Although Chen Xiao understood that he could not be the opponent of Phantom Spider, he did not really want to fight Phantom Spider to death.

If you have the opportunity, you will naturally have to keep a useful body instead of blindly dying.

Always keep a little way out for yourself, this is not a profound truth.

Faced with an invincible enemy like the Phantom Spider, you need a place to retreat even more.

At this moment, although the thin oxygen also made Chen Xiao feel very painful, it was also the only possibility to force the Phantom Spider to open this layer of cloth.

These spider silks can even ignore Xiao Ai's firewall, and Chen Xiao doesn't think he can break it quickly.

Moreover, the layers of spider silk are naturally stronger.

The fire wall that burned again did not allow the Phantom Spider to let go of the spider silk that enveloped the entire pit.

Instead, it quickly extinguishes the burning flames, with the same means as before.

However, whenever it extinguishes a firewall, another firewall will burn.

The oxygen content in the air is also rapidly replaced by carbon dioxide under the combustion of firewalls.

The Phantom Spider's actions became even more violent, and Chen Xiao and others couldn't help but lie on the ground. The thin oxygen and a large amount of carbon dioxide were there, but the ground still had a trace of living space.

The tall phantom spider is even more difficult.

In the entire space, thick smoke has blocked all sight and visibility has dropped to almost zero.

If it weren't for a gas mask, I'm afraid I would die of not lack of oxygen and would be choked to death by thick smoke.

Those flying spiders are the best result.

This kind of scene lasted for more than ten minutes, and Xiao Ai kept setting up the fire wall.

However, her movements became slower and slower, and Chen Xiao's consciousness began to become a little dazed. He himself was the consequence of severe hypoxia.

But he still gritted his teeth and persevered, and he had to let the Phantom Spider release his complete restraint on this area.

Otherwise, there is no difference between dying from hypoxia and being killed by a phantom spider.

The old monster around him also gritted his teeth and persevered.

At this time, it is about who can hold on for a longer time.

Another minute passed, and Chen Xiao, who was lying on the ground, couldn't help but peel off the gas mask.

There was little oxygen at first, and coupled with the barrier of a mask, he could hardly breathe oxygen.

The same is true for Xiao Ai and Xiao Ru, and the old demon also took off the gas mask at the same time.

They were completely lying on the ground, with their faces facing down, avoiding the thick smoke over their heads as much as possible.

The moist soil has become their only medium for self-rescue.

The seepage of groundwater also brings the few oxygen to this enclosed space.

Some oxygen contained in water can relieve the pain of hypoxia.

A large piece of soil was dug out, and Chen Xiao ignored everything else and directly pressed it on his face and slowly started to breathe.

In the soil soaked in groundwater, some oxygen is sucked into the lungs, and the body is greatly relieved due to the pain of hypoxia.

Xiao Ai and Xiao Ru also followed Chen Xiao to pick up the soil with the groundwater, and the old demon followed closely behind.

The four of them lay together like this, getting as much oxygen as possible on how much they depend for survival.

However, before they could breathe a sigh of relief, a large number of self-destructive spiders crawled towards them in the thick smoke.

The Phantom Spider was still insisting that before unbuttoning the closed spider silk, it only wanted to kill these few people.

Things came to the last step. Chen Xiao immediately untied the mountaineering bag next to him, took out several bottles of mineral water, then took out two unopened towels and handed one to the old demon.

He tied the hug tightly to his mouth and nose, poured mineral water onto his towel.

This is how much a means to maintain a short battle, but it can last unless there is enough water.

Xiaoru and Xiao Ai have veils on their faces, so just soak the veil directly.

The hypoxia condition was temporarily alleviated, and Chen Xiao immediately ordered Xiao Ai to quickly release several firewalls.

Tolerate the high temperature, block the self-destructing spider crawling along the ground behind the firewall.

He did not want to waste his energy to fight the self-destructive spider. Fighting against such a continuous suicide army, firewalls are the best means of attack.

The experience bar began to grow significantly again as a result of the death of a large number of self-destructive spiders.

And the fire wall that burned quickly consumed the last little oxygen in the air.

Chen Xiao and others could only obtain one of the few oxygen from a bottle of mineral water.

More often than not, you have to use the groundwater that penetrates out to obtain oxygen. After all, the oxygen content in mineral water is not as high as groundwater.

Moreover, there is some oxygen in the soil, which is incomparable to mineral water.

This kind of confrontation of willpower began to continue again, and the extinguished fire wall often burned again soon.

Hundreds of meters apart, Chen Xiao could feel the mania of the Phantom Spider at this moment.

This is a silent battle, persisting in speechlessness.

As time goes by, there is no oxygen in the air, and smoke completely covers the entire enclosed space.

Chen Xiao and others could no longer open their eyes, and could only perceive everything around them based on their hearing.

Four pits have been dug under their lying down, and the groundwater gathers into the small pit, forming four small pools.

This is the only thing they can save lives now, and only when they go deep into the ground can they have such sufficient groundwater.

In addition, Lu Island is surrounded by the sea, and there is never a lack of moisture in the soil.

Just waiting for now, the Phantom Spider did not let go of the spider silk around him as Chen Xiao wanted.

This made Chen Xiao slowly anxious, although he could still hear the noise brought by the violent Phantom Spider.

But the result did not change at all, there was no oxygen in the surrounding air that could be breathed, and the concentration of smoke did not drop sharply at all.

This shows that this space is still closed and no air flows in at all.

If this continues, let alone Phantom Spider, even they will not be able to stand it.

Although you can also take some oxygen from the soil and groundwater, if you are in a state of thin oxygen for a long time, your body will quickly become weak.

Even if you can breathe enough oxygen at that time, it will be difficult to recover quickly.

However, this disadvantage is the same for Phantom Spider.

Now, Chen Xiao can only choose to persevere. No matter whether the Phantom Spider will be affected, he has no other choice.

Time passed by silent persistence again, and Chen Xiao could no longer remember how long he had persisted.

Because he couldn't feel the passage of time now, there was only a blank in his mind.

The four of them lay down and didn't move, their faces were immersed in the groundwater from time to time, consuming a little bit of oxygen.

The spiders all fell down, and there was no need for a fire wall to destroy them, and they all suffocated and died.

Xiao Ai has long since continued to release the fire wall, because now, not to mention the fire wall, even a small flame cannot burn.

Suddenly, a strong vibration made Chen Xiao's almost blank consciousness immediately awaken.

The spider silk curtain inserted deeply into the ground is leaving the ground, and the enclosed space is released.

The thick smoke squeezed inside was also vented immediately and rushed out quickly.

The oxygen outside also filled in instantly. Chen Xiao, who was facing upward, greedily absorbed the fresh air.

He never felt that it was such a beautiful thing to be able to breathe, and he never felt that the place with oxygen was so comfortable.

My drowsy mind and dull chest were greatly relieved.

In the sky, the stars are reflected, and the stars are shining. Everything seems to be extremely beautiful in Chen Xiao's eyes.

"So I'm still alive."
