Boom! Boom! Boom! ……

The violent collision between the shell of the titanium snail and the rock wall of the tunnel recalls the sound of metal knocking, and the turbulence of the vortex makes it impossible for the titanium snail to maintain its balance in the water, so it can only go with the flow like this, resigned to fate.

The vortex was formed by the existence of an underground cavity that created a passage to the ocean, and now Hogu and the titanium snail where it lodges are inevitably falling deep into the earth in this way.

Poof!

The sound of falling water, the sea water that had rushed in before, provided enough cushion for Hogu.

"Luck really came home, but fortunately I chose to use titanium alloy as a skeleton, otherwise I would really have to re-develop from microorganisms."

"Anyway...... Where is this? ”

Huo Gu looked around, and the darkness that could not reach his fingers enveloped it.

“…… It seems that the visual senses need to be adjusted. ”

After receiving the instruction, the hypochlorous acid that reacts with visible light in one of the eyes of the titanium snail is replaced with a water element photolyzed under infrared irradiation, and the perspective is changed from the visible light perspective to the infrared perspective, and the original dark environment is also completely new in the blink of an eye.

"It's big!?"

Hogu marveled at what he saw, a huge underground cavern, hundreds of meters high, supported by thick stone pillars.

"It's spectacular......"

"How did this structure come about?"

Huo Gu looked around, and soon understood the reason for the formation.

There are a large number of fissures in the hollow ground, which will continuously emit tiny water vapor, like the kind that erupts after a kettle is boiled.

The underground cavern it is currently in was supposed to be filled with liquid water, but the temperature of the early planet was very high, and the liquid water absorbed heat and turned into water vapor, squeezing out the cavity through those tiny cracks, thus creating such a landform.

Retracting from the outside world, Hogu began to think about his own affairs.

"Well, I'm ...... Isn't it safe? ”

Huo Gu looked at his surroundings very unconfidently, and then breathed a sigh of relief.

"Looks like it's safe."

Thinking of what he had just experienced, Hogu felt a chill, the area within a radius of hundreds of nautical miles was changing, converted into land kilometers, it was 720 kilometers, and in terms of the scope of destruction alone, it was about a quarter of the Tsar's nuclear bomb in human history.

Hogu had foreseen many possibilities and overestimated the strength of the other party as much as possible, so he chose a position hundreds of nautical miles away as the starting point for the layout of the rhizome system.

However, what I never expected was underestimated.

That kind of large-scale crustal movement, there have been similar things on the earth, and every time it happens, it is often accompanied by a mass extinction, thanks to the fact that it is still the period of the Underworld, and the planetary ecosystem is full of microorganisms, and it is very adapted to the environment after the influence of volcanoes.

"Well, I just want to live a stable life in a relatively stable environment, how did I get to the nerves of that unknown guy?"

Humiliation and reluctance welled up in Hogu's heart, however, it was more powerless, a sense of powerlessness in the face of an opponent with unrivaled strength.

Beat?

What to fight?

The true face and location of the adversary are not known, and it is naturally impossible to talk about targeted attacks, and the destructive power is still at the level of nuclear weapons.

And what about Hogu?

It is an ordinary, mortal creature, weak and pitiful and helpless, not to mention nuclear weapons, ordinary volcanic eruptions, if it does not escape, it is also a dead end.

"I want to surrender......"

"Huh?"

Huo Gu came to his senses and paid attention to his surroundings with excitement.

"Now...... Am I in a relatively stable and safe environment? ”

"In this underground cavern, there is no strong current and pressure, and there is no need to worry about floating to the crater when resting, except that there is no light."

"Since that guy didn't pursue further and cut the grass and eradicate the roots, can it be understood that that guy can't detect creatures deep underground?"

So why don't you live in this underground cavern for the rest of your life?

"No...... No, it's too wretched, this is not the way I should live, so it's no different from a mouse in the gutter? ”

"Although I would choose life between dignity and life, it does not mean that I will not consider maintaining my dignity on the premise of ensuring life."

"Moreover, as long as that guy is still thinking about how to attack me, then I don't want to live in peace for the rest of my life, even if I don't have the ability to detect the underground now, what will I do in the future?"

“……”

"Everything else is put aside for the time being, until then it is necessary to ensure the collection of organic materials, and the development of oneself first is the last word."

"Huh, start erecting the rhizome system."

The gourd carried by the tail of the titanium snail swam out, and it attached to the bottom of the water not far from Huogu, agitated itself, and after a while, grew into a cone-shaped creature.

It begins to absorb water, just like the rest of its kind, but the difference is that the top mouth becomes a drain, and the bottom six mouths become water absorption ports.

It can't be helped, its size is too huge, and the upper mouth is already above the liquid level, so it can only be turned upside down.

During this period, there will be titanium snails, gourds, and rhizome debris washed down from above, and the collection of materials required for the rhizome system has been accelerated a lot because of this.

Soon the rhizome system grows from underneath the cone-like organisms and from the water to the shore.

Spreading all the way, the cave walls, pavement, and stone pillars were covered with a net like vines, which was a huge hollow, but it was still a small amount compared to the islands on land.

"Huh? This underground cavern is connected to other places. ”

Contrary to Hogu's expectations, several caves leading to unknown areas were discovered on the walls of several caves in the huge cavity.

"Where does it lead?"

Suddenly, through the visual system on the rhizome, Hogu's attention was focused on a rock near the mouth of a cave.

It stood quietly on the side of the cave like the gate totem of the primitive tribe, looking like a statue, but if you look closely, it is a very natural stone, and the appearance is between artificial and natural.

This made Huo Gu unconsciously think of the concept of underground people......

It hastened to dispel these unrealistic fantasies.

"What the hell is going on? How can there be so many unrealistic fantasies lately? This is the Underworld, which is not suitable for large creatures, so it ......"

When Huo Gu said this, he was stuck, and his eyes stared directly at the stone that seemed to be a handicraft next to the cave and couldn't move away for a long time.

“…… Sure enough, it's better to go inside to confirm. ”
