The orange sky is yellow, as if there is a layer of yellow mist covering the sky, and it is like wearing yellow sunglasses to look at the sky, the sun seems very blurry, and the earth is very quiet.

Yes, tranquility!

Compared to the hustle and bustle of the earth, this planet is completely different, there is no singing of birds, no neighing of insects, no running of animals, no noise of humans.

It's a planet with zero noise, absolutely quiet.

Xue Yu lay on his back by the lake, enjoying the pleasure of life energy flowing in his body, this is all the work of Xiao Lu, without Xiao Lu, he would not dare to come to this planet.

"Whoa"

Suddenly, a faint ripple was quietly drawn on the surface of the water not far away, and the ripples gradually extended from the center of the lake from far to near, swimming towards the shore, as fast as lightning.

This scene, Xue Jun lying on the ground did not notice it.

"Wow"

Suddenly, a gentle sound of breaking water broke the silence of the lake, and I saw a silver creature shoot out of the water, twisting its body and instantly wrapping around Xue Su's ankle.

"Zizizi"

Suddenly, like the sound of a saw cutting through iron, Xue Jun only felt his ankle tighten, and then bounced up, and saw a silver creature like a snake tightly wrapped around his ankle, his body constantly squirming, making a "zizi" cutting sound.

"Dare to sneak up on me!"

Xue Xu's heart moved, three or four spikes appeared at his ankle, and the silver creature was pierced in an instant, and the "squeak" silver creature let go of Xue Shu's ankle, screamed twice, and fell to the ground motionless.

"This is the creature unique to Planet 15?"

Xue Yu bent down and took the silver creature in his hand, and looked at it carefully, this thing was only the thickness of a thumb, but it was more than two meters long, like a snake, but more like a silver earthworm.

Because it has no head!

But on one side of its body, there is a jagged line that runs from one end of the body to the other, and this jagged organ is the teeth of the silver creature.

These teeth are metal teeth!

Xue Jun stretched out a finger and gently touched this row of teeth, and sure enough, the familiar itching sensation rose from the fingers and began to devour this row of teeth.

"Sure enough, it's metal, and not only the teeth, but also the blood of this little thing, and many organs in the body are rich in metal elements!"

When this silver "little snake" was devoured, only a piece of dry skin remained, as well as a little non-metallic organ, and most of the substances in the body were devoured by Xue Xu.

It can be seen that the body of this little snake is rich in metallic substances.

In fact, it's not just this little snake, most of the matter in the body of all creatures on this planet is almost entirely made of metal elements, just like the human body, most of the matter is made of carbon.

All living things, rich in metallic elements.

The whole planet, rich in metal deposits!

This is the real reason why Xue Yu came to this planet, he wants to become stronger on this planet by fighting monsters and devouring metal.

"And this lake!"

Xue Jun walked to the lake, looked at the quiet mirror-like lake, and there was a faint hint of determination in his eyes, the water surface was silver, just like silver.

This lake is not the kind of lake formed by water on earth, but a lake of mercury formed by mercury.

A whole lake, all mercury, does not evaporate, does not reduce, and stands on the earth forever and ever, constituting a habitat and constituting the cradle of the evolution of life.

This is the magic of Planet 15.

Mercury lakes, mercury oceans!

Life conceived and evolved in mercury!

The wonder of the universe is vividly reflected here, and even scientists on Earth would never have thought that life can be born without water, and mercury can also give birth to life.

They also don't think about how complex the situation of life in the universe is, how can they look at the universe from the perspective of life on earth?

"Puff"

Gritting his teeth, Xue Yu jumped forward, swept a perfect arc, and jumped into the lake!

As soon as he entered the water, his whole body only sank a little, and then he was ejected from the water, and then floated on the water, and could not go down again, "The density of mercury is too great, I want to sink to the bottom of the lake, it seems impossible!" Xue Yu couldn't help but smile bitterly.

He knew very well that mercury was very dense, and the human body was very dense, so it would float on the surface of the water and not sink.

This is different from the lakes and oceans of the earth!

But Xue Jun is not worried that it will not sink, because

Sensing Xue Shu, an outsider, a large number of lake creatures came from all directions, wrapping around Xue Shu's legs and waist, and rows of metal teeth kept wriggling, trying to bite Xue Shu to pieces.

Almost all of them are small silver snake-like creatures, some are big, some are thick and some are thin, the big ones are as thick as arms, more than twenty meters long, the small ones are only the point of toothpicks, ten centimeters long, and in just a few minutes, Xue Yu's body is crawling with this kind of small silver snakes.

The density of the small silver snake was very large, so Xue Yu's body was dragged to the bottom of the lake.

"Let's go!"

Feeling that his body was completely submerged by the lake, Xue Jun's eyes flashed, and five sharp claws shot out from each of his hands, and then slashed at the small silver snake that was surging towards him.

He will not kill the surface of the body, but in all directions, this is training, he has to train himself in the mercury lake, hone himself!

"Sting"

The sharp claws were extremely sharp, and in an instant, they cut a small snake in half, and Xue Jun continued to wave his arm and slash the next one.

But the swing of the arm is very strenuous and very difficult, just like in a swamp, and each stroke consumes a lot of physical strength.

Mercury, it's too heavy, the resistance is too great!

This requires a lot of Xue Yu's physical strength!

"Haha, that's what you want!"

Xue Yu is not in a hurry but happy, he came to this planet to hone himself in an absolutely difficult environment, waving his arms in the mercury to kill monsters, just like cultivating in the deep sea, the resistance is very great.

Nine times the Earth's gravity can make this drag even greater.

Strong combination, two by two, the effect is by no means as simple as one plus one!

"Whew"

It only took more than twenty swings to kill 4 small silver snakes, the speed of these guys is too fast, the streamlined body makes them swim as fast as lightning, on the other hand, Xue Yu is as slow as a turtle.

"Kill"

Xue Yu was not discouraged and continued to wave his arms

Strong resistance, 9 times the gravity, under this double high-intensity torment, Xue Shu didn't last long, and he felt that his arm was sore, as if he had been filled with lead, and it was extremely heavy.

"Little Green," Xue Jun whispered.

Xiao Lu, who was lying on his chest, naturally input life energy into Xue Xu's body, and with Xiao Lu's vigorous output, in just twenty seconds, Xue Lu became energetic again.

"Kill"

This is a cultivation that even Xue Yu doesn't know the deadline, I don't know how long it has been honed, I don't know how many silver snakes have been killed, and I don't know how many times I have been "milked" by Xiao Lu.

When the alarm of oxygen falling below 10% came from the spacesuit, Xue Yu suddenly woke up and killed all the silver snakes wrapped around his body.

When the lake reappeared, the sky had become extremely dark, and the stars had long since disappeared, replaced by five large, round, but hazy moons!

It's like a veil!

It's night!

"So I've been at the bottom of the lake for 23 hours!"

Xue Yu muttered to himself, he was dizzy now, and his spirit was a little numb: "I have to go back to the base city to replenish oxygen, but I don't know if I am wanted in the city?" ”

This is exactly what Xue Yu was worried about, when he came out, he only carried a set of metallurgical spacesuits, and other than that, he didn't bring anything, with Xiao Lu, these are really not needed, but the metallurgical spacesuit can only last for 24 hours, and the energy will be exhausted.

So, I have to go back in 24 hours.

"Go back, go back! However, I secretly went back, and after supplementing the oxygen, I quietly left! ”

Xue Yu thought that the maintenance of the metallurgical spacesuit was very simple, put it in a place with sufficient light and air, it would automatically replenish, and it would not require too much maintenance, he believed that as long as he was careful, he should be able to avoid being wanted by the base city.

"But before I leave, I'll have to take this lake with me!"

Looking down at the mercury lake under him, Xue Jun directly removed the liquid gold spacesuit on his body, exposing his body to the mercury, he wanted to devour, devour this huge mercury lake.

Xue Yu knew very well that in this state of devouring, he did not need to consume oxygen, and even if he removed the spacesuit, he would not die!

Suddenly, the familiar itching sensation came from all over the body, and the heart began to devour the mercury in the lake, although the mercury was liquid, it was an authentic metal, as long as it was metal, Xue Yu could devour it.

"Ahh

With Xue Yu's body as the center, a whirlpool gradually formed, and the whirlpool became bigger and bigger, devouring mercury wantonly, and under this high-intensity devouring, it was accompanied by high-intensity severe pain.

"Little Green"

Midori injected energy into Xue Yu's body

With the dual transformation of metallic energy and life energy, Xue Yu's cells began to mutate, and his soul continued to begin to undergo unfinished second-degree mutations.

The cells continue to mutate in phagocytosis, and the soul also continues to mutate in the second degree in phagocytosis.

Torment, devour, mutate!

Torment, devouring, second-degree mutation!

Time passed little by little, Xue Yu was tormented in pain, he was almost dead and alive, he wanted to be unconscious, but this time he couldn't be unconscious, he could only grit his teeth and endure it, he could only endure this pain for life.

1 bell, 2 bells, 3 bells

In the blink of an eye, 10 minutes passed, and the originally huge lake shrank severely, and the water level dropped again and again, leaving only a very shallow layer, and many small silver snakes struggled and bounced in the shallow water like fish.

The water level is about to dry up, and they have to die!
