Looking at the heavy liquid on his hand that reflected his distorted reflection, he frowned slightly,

Because Su Yun was wearing bionic power armor at this time, he was not smart at touch, and he could only feel some weight slightly, so he was not sure whether the silver liquid in the waterhole he was stepping on at the moment was mercury, so he quickly asked the Q version girl to help analyze the ingredients, and then checked his life support system, after all, even the mercury vapor volatilized in such a large stall is fatal to Su Yun,

Everything is normal in the life-sustaining system, and the results of the Q version of the girl's analysis show that these things are indeed real liquid mercury,

These mercury had a good shielding effect on the Q version of the girl's scan, so although Su Yun was able to get the image map of the huge cave from the Q version of the girl's scan, the places covered by the mercury were all blank, and it was just this way to judge the specific size of this mercury lake,

The entire mercury lake occupies more than two-thirds of the current cave, although the surface presents a very irregular oval shape, but the estimated area is about more than 20,000 square meters, just looking at the surface area has exceeded the standard size of 16 Olympic swimming pools, it is not too much to describe the lake.

On the earth, although mercury is also elemental, it is more in the form of compounds and inorganic salts, and such a large lake formed by liquid metal mercury suddenly appeared in front of him, Su Yun inevitably felt a little overflowing in his heart, but fortunately, the impact of the golden desert he saw before was still there, and Su Yun was also a person who had seen the world anyway, so he quickly retreated from the shock and began to think carefully about the current problem.

First of all, he found a huge hole in the rock wall near the entrance where he was, looking at the size and newness of this hole, it was obviously caused by the cosmic worm larvae that swallowed Su Yun before, originally Su Yun thought that he would have to fight with that guy anyway, thank you for the current situation caused by it, but I didn't expect it to turn a corner here and escape directly,

But at the moment, it seems that the way this cosmic worm larvae behaves is very weird, and after arriving here, it does not hesitate to dig a hole and escape with a heavy wound, obviously there is something here that makes it instinctively unwilling to face,

The first thing Su Yun thought of was the huge mercury lake in front of him, but he quickly denied his idea, although mercury is a deadly poison for humans, but for the cosmic worm, a biological black hole known as the devourer of the world, not only is there no problem in this regard at all, but in a sense, it is still enough food for ten minutes.

After all, in some records, the adult form of these guys can even directly devour stars, and it is easy for such a good stomach to digest mercury, so what else is there to force it to flee except for this huge poisonous lake?

Su Yun cautiously searched along the vicinity a little, and did not find any useful clues, he couldn't help but feel that he was too nervous, and the shadow of the novice base before blew up made him a little nervous, thinking about it carefully, although the adult body of the cosmic worm is a super S-level cosmic disaster, but the larvae are relatively much weaker, and the time it takes to grow to that point is calculated in hundreds of millions of years, and according to the size of the previous one, it is estimated that it has just entered the juvenile stage, There are so many things that can threaten it at this stage,

Even Su Yun was able to open a hole in its stomach with a mining gun before, and the crisis in its opinion should not be as exaggerated as Su Yun imagined.

Random speculation here is not a way, practice is the only criterion for verifying the truth, if there is really any unknown threat, at least you can prepare earlier, after all, this place is now connected to Su Yun's underground base, and what is even more strange is that this place does not exist at all on the holographic map given by the virtual girl, in other words, this cave, including this mercury lake, only appeared in this hundred and sixty years, and the specific cause, function, and purpose of its formation are unknown,

It's as if someone has forced another paragraph in history, and the sense of disobedience is very strong.

At this time, because the restoration work of the medical cloning center had been completed, Su Yun had a little bottom in his heart, so he simply explored this cave along the mercury lake in front of him, throwing some energy crystals as markers and light sources along the way, but the result was sparse and ordinary, as before, there was no useful discovery, as if this huge cave had been dead for a long time, and there was nothing that could be called a threat.

Is it at the bottom of this lake?

Since there is no one on the shore, Su Yun naturally focused his attention on this mercury lake, after all, looking at the area of this thing, it is too easy to hide something, but I don't know the depth of this mercury lake, and the Q version girl can't scan it, but when Su Yun stepped on it before, he felt that the terrain there was a steep downward slope, if they were all calculated according to the same gradient, the central depth of this mercury lake was estimated to be far beyond imagination,

Dive down and try it?

Su Yun shook his head slightly, although he was very inclined to go down and explore, but the density of mercury is 13.6 times that of water, and theoretically even a solid copper ball can float on it, he had already felt the unparalleled buoyancy of this thing when he fell down before, although less than half of his body was below, the huge buoyancy even had a tendency to directly squeeze Su Yun out,

And the gravity on this planet is much smaller than that of the earth, without the help of such an important factor, if you only have a volume the size of a water tank, it is estimated that it is possible to dive down with a little effort, but at the moment this is a lake, with Su Yun's current equipment, it is tantamount to a fantasy to dive,

Not to mention finding the secret hidden in the liquid metal with infinite transmittance close to zero, this thing was used to produce mirrors before it was replaced by silver and aluminum, in which Su Yun didn't even have a centimeter of vision, in this state of not being able to see anything clearly, he couldn't even realize it if something went wrong, not to mention that what he went to find was not necessarily a needle, it was likely to be a nuclear bomb,

Thinking about it, the resources at hand may be a little insufficient, and it is estimated that I have to go back to see if I can ask the virtual girl to get some sonar and other detection equipment that can penetrate mercury, at least I have to understand the following environment first, and then say, now I am so reckless, maybe I will explain my blood here,

Immediately decided, Su Yun no longer hesitated, turned around and retreated to the tunnel where he came, and decided to go back to the base first.

Not long after Su Yun left, the mercury lake, which should have been still and without waves, suddenly produced a slight fluctuation, expanding a few meters around it like a rising tide, and then the ebb tide returned to its previous state, as if nothing had happened.

The only change was that the energy crystals that Su Yun had casually thrown by the lake as a marker and light source had disappeared.
