The rhizome system spreads into the discovered caves, Huo Gu thought, since he wants to explore the caves, he should explore the other caves as well.

　　 These caves are deep and winding, full of mystery. On the walls of the caves can be seen colorful and mysterious luminous crystals.

　　 Of course, this is only true for humans who are still in the mortal womb with naked eyes.

　　 Huogu is no longer human now.

　　 "Oh, it turned out to be like this. This should be the channel through which lava used to flow. The high temperature will extract silicon and then mix it with trace radioactive elements in the formation."

　　 "The strongest evidence is that the rock wall is made of pyroxene rich in metal elements..."

　　 Huo Gu, who had analyzed here, was stunned for a while, and it took a while to react, and looked at the crystals on the cave wall with horror, as if watching a group of evil spirits crawling out of hell.

　　 "Fuck! There is nuclear radiation in this place?!"

　　 "Rhizome system, thickening the rhizome epidermis of the hole**."

　　 Huogu issued an order and searched for elements like lead in the area covered by the rhizome system. Elements that can absorb radiation are added to the epidermis of the rhizome.

　　 After a lot of confusion, the exploration continued, and the rhizome group gradually pushed deeper into the cave.

　　 "Huh? Is the channel wider?"

　　 "Don't worry about so much, keep going."

　　 The deepening behavior of the rhizome continues, and the situation is completely reversed when I first entered. When I first entered, the passage became narrower and narrower, but now it is getting bigger and bigger.

　　 seems to have reached the end of the passage. Huogu can clearly feel the air flow touching the epidermis through the rhizome, which means that this place is the outside world, or the inner space is huge enough to form the air flow.

　　 Now Huogu is exploring downwards, which obviously belongs to the latter.

　　 "No way...Is there really an underground world?!"

　　 The rhizome spreads out of the passage, and Huogu's vision also leaves the passage, and he sees the scenery at the end of the passage.

It’s big, it’s so big that it’s indescribably big, with no end in sight, no end on the left, no end on the right, and no top from above. It's like a place in a ghostly foreign land. The underground cave where Huogu fell from the sea before. Compared with this, it can only be regarded as a small room at best.

　　 "This, how did this come into being?"

Huo Gu somewhat suspected that he had hallucinations, and the scene he saw now was once again beyond its scope of knowledge. In theory, this kind of environment should be extremely difficult to form. Even if it is possible to form, it will be caused after a period of time. The upper mass is too heavy to cause collapse.

　　 But this is obviously not a newly formed underground cavity!

　　 At this time, several other caves have also been explored to the end. There is also an underground cavity, but compared with this one, it seems that an elephant is comparing its size to an ant.

　　 Now there are two choices in front of Huo Gu, continue to go deeper and stop there.

　　 "Well...there is no water in these underground cavities, so if the distance continues to extend, the difficulty of transportation will increase."

Different from the rubber pipes of human beings, every part of biological pipes built by cells like Hogu needs water for maintenance. That is to say, as the transportation distance increases, the less water is transported in the past. .

　　 "The other underground cavities have not been explored yet, so it is better to suspend the exploration of this super huge underground space first, and first set up a non-biological pipeline to transport water, and I can also see what is in the other cavities."

"that is it."

　　 Huogu shifted his perspective and switched to other underground cavities.

　　 With the shock of the super giant cavity before, now these cavities two to three times the size of the underground cavity that fell into it at the beginning can no longer make Huogu's heart rise.

　　 Compared with the outside, the cavity is very ‘barren’ because there is no liquid water and material-providing lava, there are very few bacteria that can breed, and the cost of exploring the rhizome system is so huge.

　　 Huogu soon discovered an embarrassing fact that it ran out of organic materials.

The underground cavity is too big, and the materials that can be collected are too few. In fact, the organic materials should have been exhausted long ago. It can last for so long because there are rhizome debris from time to time above, or gourds and titanium snails that are caught in the whirlpool. The ancients reclaimed these organic materials to survive until now.

　　 "What should I do? Even if the rhizome system grows fast enough, the pace of exploration will be slowed down."

　　 Huogu's gaze was directed to the hole where the sea water has been gushing, that is the only passage that connects the ocean above, it currently knows.

　　 "Go out?"

　　 "No, no, this is definitely not good!"

　　 The thought was horrified and denied as soon as it rose. The indescribable existence outside caused the psychological shadow on Huogu, and it is estimated that it can cover the entire planet's surface according to the area.

　　 Before he mastered enough power to contend with, Huo Gu would not consider appearing in the field of vision of that kind of guy.

　　 "If... other creatures, would that guy also attack?"

　　 Huogu came up with such an idea. UU reading www.uukanshu.com would think so because it was inspired by the current lack of organic raw materials ‘microbes’.

　　 From the very beginning, the unidentified guy seemed to have been staring at Huogu, while turning a blind eye to the microbes in the ocean.

　　 This shows that it can distinguish the difference between Huogu and other life. It is precisely because it can distinguish this difference that it will be so directed at Huogu and turn a blind eye to other creatures.

　　 It's actually quite simple to think about it the other way around. Huogu can use this to create some autonomous creatures, let them collect organic materials in the ocean, and then deliver them to the whirlpool.

　　 Thinking of this, Huo Gu hesitated, because this is the creation of real life, not biological tools such as gourds and titanium snails, they will have the concept of ‘I’.

　　 This involves many concerns of Huogu, which is why Huogu would rather have a delay in the command than design some real macroscopic creatures with autonomous intelligence.

　　 "Such creatures are designed, can I control their cells as I do now?"

　　 "Will they still follow my instructions? Will they attack me in turn?"

　　 "Restriction is impossible. Life will always find a way out. If one day, this creature gives birth to wisdom and knows my existence, how would it treat me?"

　　 "...According to the human temperament, it is estimated that God will be hacked to death on the street."

　　 sounds very far away, but Huogu is already immortal, and hundreds of millions of years are just a flash for it, and the remote problem is essentially close at hand.

　　 If you don’t understand, you can understand it in another way. The summer vacation sounds like a long one. There are two months. In fact, after playing around, you will find that it is the last day of the vacation and the homework hasn’t moved.
