咣! Huh! Huh! ...

　　 The violent collision between the shell of the titanium snail and the tunnel rock wall recalled the sound of metal percussions. The turbulence of the vortex made the titanium snails unable to maintain balance in the water, and could only follow the flow like this, resigning to fate.

　　The formation of the vortex is due to the existence of an underground cavity that leads to the ocean. Now Huogu and the Titanium snail it hosts are inevitably falling into the depths of the earth in this way.

　　噗通!

　　 The sound of falling into the water, the seawater that poured in before provided enough buffer for Huogu.

　　 "Luck is really back home. Fortunately, I chose to use titanium alloy as the bone, otherwise it would really be re-developed from microorganisms."

　　 "By the way...Where is this?"

　　 Huo Gu looked around, surrounded by the invisible darkness.

　　 "...It seems that the visual sense needs to be adjusted."

Upon receiving the instruction, the hypochlorous acid that reacts to visible light in one of the eyes of the Titanium screw was replaced with the elemental water that photolyzed under infrared light, and the angle of view changed from the angle of visible light to infrared angle, which was originally pitch black. The environment is also getting a new look in a blink of an eye.

"so big!?"

　　 Huogu marveled at the sight before him, a huge underground cavity with a height of several hundred meters, supported by thick stone pillars.

　　 "It's so spectacular..."

　　 "How is this structure formed?"

　　 Huo Gu looked around and quickly understood the reason for the formation.

　　 There are a huge number of cracks on the hollow ground, and these cracks will continue to spray out small water vapor, just like the kind that gushes out after a kettle is boiled.

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

　　 Withdrawing his mind from the external environment, Huo Gu began to think about his own affairs.

　　 "Well, I am like this now...should be considered safe?"

　　 Huo Gu looked at the surrounding environment without confidence, and then heaved a sigh of relief.

　　 "It seems to be safe."

Thinking of what he had just experienced, Huogu felt a chill. The area of ​​hundreds of nautical miles was changing. If converted to land kilometers, it would be 720 kilometers. In terms of the scope of damage alone, it is about the same as in human history. A quarter of the Tsar’s nuclear bomb.

　　 Huogu had previously anticipated many possibilities and overestimated the opponent's strength as much as possible, so he chose a location hundreds of nautical miles away as the starting point for the arrangement of the rhizome system.

　　 However, I never expected it to be underestimated.

That kind of large-scale crustal movement, there have been similar things on the earth, every time it happens, it is often accompanied by a mass extinction of living things, but it is still in the era of the ancient universe, and there are microbes in the planetary ecosystem. , And very adapted to the environment after the volcanic influence.

　　 "Oh, I just want to live a stable life in a relatively stable environment. How can I touch the nerves of that unidentified guy?"

　　 Humiliation and unwillingness emerged in Huo Gu's heart. However, more of it was powerlessness, a sense of powerlessness in the face of an opponent with unmatched strength.

hit?

　　 What to fight?

　　I don't know the opponent's true face and location. A targeted attack is naturally impossible to talk about. The destructive power is still at the level of nuclear weapons.

　　 And Huogu?

　　 It is an ordinary, mortal creature, weak, pitiful and helpless, let alone nuclear weapons, ordinary volcanic eruptions, if it does not escape, it will be a dead end.

　　 "I really want to surrender..."

"Ok?"

　　 Huo Gu came over slowly, paying attention to the surrounding environment with excitement.

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

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

　　 "Since that guy didn't pursue any further, cutting grass and roots, can it be understood that that guy can't detect creatures deep in the ground?"

　　 So why not live in this underground cavity for a lifetime?

　　 "No...no, it's too awkward, this is not my Huogu's way of living, so it will be no different from the mouse in the gutter?"

　　 "Although, between dignity and life, I will choose life, but this does not mean that I will not consider maintaining my dignity on the premise of guaranteeing life."

　　 "Also, as long as that guy still thinks about how to attack me, then I won't think about peace in my life, even if I don't have the ability to detect underground, what will I do in the future?"

　　 "……"

　　 "All other things are set aside for the time being. Before that, it is necessary to ensure the collection of organic materials. It is the last word to develop yourself first."

　　 "Gourd, start to erect the rhizome system."

　　 The gourd carried by the tail of the titanium snail swims out. It attaches to the bottom of the water not far from Huogu, agitates itself, and after a period of time, it grows into a cone-shaped creature.

　　 It starts to absorb water, just like its other similar ~lightnovelpub.net~ However, the difference is that the uppermost mouth becomes a drainage port, and the lower six mouths become a suction port.

　　 No way, its size is too huge, the upper mouth is already above the liquid level, so it can only be turned upside down.

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

　　 Soon the rhizome system grows from under the cone organisms and grows from the water to the shore.

　　 spread all the way, cave walls, pavements, and stone pillars were covered with a net that looked like vines. It was said to be a huge hole, but compared with islands on land, it was still insignificant.

　　 "Huh? This underground cavity is actually connected to other places."

　　 Unexpectedly, Huogu discovered several caves leading to unknown areas on the walls of the huge cave.

　　 "Where will it lead?"

　　 Suddenly, through the visual system on the rhizome, Huogu focused his attention on a rock near the mouth of a certain cave.

　　 That thing stands quietly on the side of the cave like the gatekeeper totem of the primitive tribe. It looks like a statue, but when you look closely, it is a very natural stone with an appearance between artificial and natural.

　　 This makes Huogu unconsciously emerge the concept of underground people in his mind...

　　 It hurriedly dispelled these unrealistic fantasies.

　　 "What the **** is going on? How come there are so many unrealistic fantasies recently? This is the ancient universe, and it is not suitable for large creatures to live in an environment, so..."

　　 Huogu said that he was stuck, his eyes fixed on the stone that was suspected to be a handicraft beside the cave and could not be removed for a long time.

　　 "...Sure enough, it's better to go inside and check it out."
