The water was cold, and when Chen Jin tested the temperature of the water with his fingers slightly, he knew that with his current cultivation, he couldn't go into the water no matter what.

Helpless, Chen Jin had no choice but to go to the Haierfa Dakeng base.

Due to the frequent occurrence of interstellar wars, most of the craters built on the base are interstellar warships, and the submarines have not been updated for a long time, although they are relatively backward products, but compared to the submarines on the earth back then, they are still too much surplus, Chen Jin didn't think much about using the storage ring, and collected two or three submarines and returned to the waterhole.

Putting the submarine into the pool, he and the robot also boarded the submarine, closed the hatch, and sank.

Just listening to the buzzing sound, the submarine went all the way down, at the beginning of the entire waterhole except for the sound of the submarine there was no other movement, but as time went by, there were slowly more fish-shaped spirit beasts around, and the spirit beasts living in this kind of place were strong and terrifying, and the submarine was swayed for a while, but Chen Jin was not surprised by this, after all, the ultimate micron was all over the waterhole, and these fish monsters were also expected by him, so he sent a few Yuan Infant Candle Dragon Robots to kill them.

Moving on, the water in the waterhole has become more and more terrifying, the water pressure is getting higher and higher, and the water also has a trace of corrosive aura.

It didn't take long for Chen Jin's submarine to finally reach the limit of the ultimate trizuno coverage area.

Further down, the terminal neutrino will also fail.

However, in the last covered area of this ultimate micron, there is a seemingly dead tree vine, the tree vine is diagonally inserted on the rock, and the submarine headlights still reflect the light of metal, but Chen Jin knows that a tree vine can not be corroded in this kind of place, and this tree vine is definitely not an ordinary thing.

Chen Jin controlled the submarine's working arm and grabbed the tree roots back to the submarine. Looking at the root of the tree in front of him, Chen Jin had never seen this thing, this thing was extremely hard but extremely tough, making people think that it was a root cast of steel, but Chen Jin looked at the fracture of the root of the tree and found that the bark and tendons at the fracture were distinct, it was obviously the root of a plant, and it seemed that it was not clear for the time being.

After diving for so long, but picking up a useless thing, Chen Jin couldn't help but feel a little depressed, but after thinking about it, he could go down to such a deep place, and if he was someone else, there was no one who could enter the cultivation of the land of trials beyond the foundation building period, who could go so deep.

Although there is no ultimate neutrino coverage below, it is a pity to go back after diving so deep, so let's continue to have a look.

As Chen Jin went deeper and deeper, the water in this pool gradually turned pitch black, the water was still cold and piercing, and the effect of corroding spiritual power became more and more terrifying.

Chen Jin even dared to conclude that no one had ever been to this place except himself, after all, this water would definitely corrode you cleanly when it touched something with spiritual power, unless it was an immortal, and all the mana in the body had been transformed into immortal power, so there was no need to be afraid of this water.

However, Chen Jin didn't care, the submarine didn't have any aura, and the water wouldn't corrode the submarine at all.

As the submarine sank deeper and deeper, the humming sound of the machine became very strange, and it seemed very strange, what was so special about this waterhole that even the sound could swallow up.

The speed of the submarine built at the base of the big pit was more than enough to travel two or three thousand kilometers in an hour, but Chen Jin sat in the submarine and drove for an hour to reach the bottom of the pool.

Seeing this, Chen Jin realized that the water in the pool did not have the characteristics of corrosion, but the ability of the silt at the bottom of the water to absorb the aura was too terrible, so that the pool water absorbed the aura everywhere.

Chen Jin looked at these silts and was very curious, he didn't know why some mud absorbing spiritual energy would be so terrible, so he threw a low-grade spirit stone into it, and the spirit stone had not fallen into the silt, but it was instantly sucked dry by the pool water, and the spiritual energy was left with only a whitish stone falling into the silt.

Weird, this silt is too weird, if you get out of the submarine, I'm afraid that it will be sucked dry by the pool water in an instant, and then crushed into pieces by the terrifying pressure in the water.

I have to take some silt and study it, Chen Jin thought to himself.

So Chen Jin operated the mechanical arm, grabbed a little bit of silt and entered the dark compartment of the submarine, and because he was separated from himself by a very thick alloy plate, he couldn't absorb the mana in his body.

Chen Jin's research method is also very simple, doesn't this thing like to absorb spiritual power, anyway, he lacks everything and there is no shortage of spiritual stones, but he wants to see how much spiritual energy this thing can absorb.

Suddenly, the dark grid with the silt was put into more than 300 high-grade spirit stones by Chen Jin, and the aura of the high-grade spirit stones was huge and pure, and Chen Jin didn't believe that some of the silt could be absorbed.

But what Chen Jin never expected was that after a short period of effort, more than 300 high-grade spirit stones were collectively whitened, and after insisting on it, these spirit stones were completely white.

Chen Jin, who saw this scene, was stunned, when did the aura of the high-grade spirit stone be so inhaled.

Gritting his teeth, Chen Jin cleaned up the whitish spirit stones that had been sucked, and took out two thousand high-grade spirit stones from the storage bag, stuffing the entire dark grid to the brim, since you can suck it, let you suck it enough at a time.

According to the absorption rate of silt, two thousand spirit stones are only the time of one tea, when the time of one tea, most of the spirit stones have been absorbed and only one or two are still with the luster of spiritual energy, and the silt is buried in the pile of spirit stones, and there is no trace.

After another cup of tea, the aura in the spirit stone was still there, and Chen Jin knew that the mud could no longer absorb the aura.

The corners of Chen Jin's mouth twitched secretly, it was terrible, such a small handful of silt actually absorbed more than two thousand three hundred high-grade spirit stones, if the silt in the entire pool land absorbed spiritual energy, how many spirit stones could be obtained.

Shaking his head and not thinking about it anymore, the white spirit stone in his hand was swept aside, leaving only the mud full of spiritual energy.

Carefully looked at these "monsters" who ate spirit stones, the mud was no longer like silt, and the state of absorbing spiritual energy was like a stall of jelly, which was completely different from the previous form of silt, Chen Jin rubbed it, and the feel was similar to a spiritual soil, and it was still a mud when he was messing around, and he didn't know what it was for.

By the way, spiritual soil, this thing is silt, and silt is also soil, so don't you know if you get something and plant it?

As soon as he raised his hand, several dragon's beard plants appeared on the silt.
