Perpetual they were briefly stranded in front of a river left behind by the towering peaks in the center of the floating island, and they needed to replenish their supplies, this river was not water, but liquid hydrogen, where the gatherers could replenish the energy they had just spent in battle, with a little bit of chemical synthesis skills. ，

In order to replenish the supply, the egg-shaped organism is temporarily unable to move, which makes some gatherers bored, and try to reach into the liquid hydrogen river with their tentacles, and when they fish it out again, the part of the tentacles that have reached into the liquid hydrogen has disappeared without a trace, disappearing into the vast ice river.

"What are you doing?"

"Out of curiosity, I want to experience its temperature and get relevant data."

"You're wasting resources, we have limited materials."

"It's okay, this little resource can be replenished at once, this kind of river is very interesting, why don't you go back to the twilight and arrange some on it?"

"Waste, inefficiency, rejection."

"That's right, the liquid hydrogen that has lost its pressure is just flowing outside, it's too wasteful."

"That's what you say, that's true."

After thinking about it, the gatherer gave up on the idea of adding some ornamental scenery to Twilight, but it didn't take its attention off the river of liquid hydrogen, as some small figures scurrying out of the river caught its attention.

Suddenly, a cold light flashed, unimaginably fast, and the tentacles of the egg-shaped creature pierced through the small creature that had just jumped out of the cold river, and pulled back to observe.

The creatures are similar to fish, with the same fusiform appearance, which allows them to reduce their resistance in liquids to the maximum of a powerful tail that acts as the driving engine of the river, providing the basis for moving in the river and jumping out of the river. ，

A spine extends from the skull to the end of the tail, and the musculature is mainly distributed around the back to give them strong motivation.

Not only in appearance, but even in action, it is quite similar to a torpedo, such as now, constantly struggling in vain on a monomolecular blade that pierces itself

"Look, it's another interesting design, the muscles are wrapped on the outside, and the bones are on the inside to support the whole body, while protecting the main internal organs."

"What's this, aliens and creatures on their home planet, isn't it that this biological structure is not strange, but the design is very interesting, I have seen a creature with a battery structure for the first time"

The body fluids of these fish-like creatures are acidic corrosive fluids, and with the bone structure, they become a battery, and every time they jump out of the river, it is not to enjoy the scenery outside the river, but to move themselves back and forth between low temperature and normal temperature, using the large temperature difference to make the metal skeleton generate electricity, which will be absorbed and stored by the battery structure after it is generated.

As for the use of this electrical energy, reality quickly informed the sustainable collectors with facts.

Forever they saw the flying creatures in the sky again, and they came to prey on the fish-like creatures, their fangs and claws skimming the surface of the liquid hydrogen river at high speed and care, grabbing the fish-like creatures that had just jumped out of the river.

Unlike gatherers, flying creatures don't cause much damage to fish-like creatures at first due to their shape, which gives them a chance that they won't be eaten.

A crackling electric shock sounded, and the flying creature froze and fell into the liquid hydrogen river with the fish-like creature, and the result was obvious, the flying creature was completely frozen by the low temperature, and then it was washed by the river, and it shattered into a pile of ice slag, following in the footsteps of the same tentacle that a certain gatherer had sacrificed for the death just now.

However, the fish-like organisms survived because of their adaptation to the environment of the liquid hydrogen river.

Of course, not everything goes smoothly, and some flying creatures rely on gliding and do not fall into the river of liquid hydrogen, and then the result is another matter.

Occasionally, there will be a lose-lose situation, and the flying creatures will either die or be crippled by the branches on both sides of the river bank that they collide with in the gliding, and the fish-like creatures will be thrown onto the shore of the principle liquid hydrogen, and gradually jump in vain towards the end of their lives.

Life is like this, to survive in the fight, if you can't do it, there is only one way to die, this is nothing, as early as a long time ago, the gatherers deeply understood this truth, and there is no intention of interfering.

However, what happened later made them change their minds

The fish-like creatures jumping on the ground feel the proximity of death, they don't want to die, but the sesame-sized brain can't think of a solution at all, in their cognition, death and the enemy are linked, so death is close to means that the enemy has not been repulsed, not repulsed because the electrical energy is not released enough, by this kind of fish creature in the process of jumping, will continue to release electrical energy, until the electric energy is completely exhausted, life comes to an end.

When the fish-like creature's body touched a patch of fungus on the ground, it was evident that the collectors had picked up a familiar electromagnetic signal, which had no readable information, but was the same frequency band that the collectors had captured in space

"Change your mind and kill all the people who get in the way."

"Understood, start locking on multiple targets."

The hearing organs of the flying creatures keenly picked up bursts of breaking through the air, as if something was moving at high speed, but they did not catch any unknown targets from high in the air, so they appeared a little dazed.

In the blink of an eye, the opportunity was fleeting, and the flying creatures wasted their last chance to escape, one by one the flying creatures were pierced by tentacles, and the monomolecular blades cut them all into large pieces without resistance like slicing tofu.

Of course, the flying creatures can't find anything, because the attack is simply launched from the ground, and what can be found when you look at the sky

It didn't take long for the battle of the gatherers to end, no, it can't be said to be a battle, it should be said that the efficient s are over, except for a few flying creatures that are far away, most of them have become fallen souls of monomolecular blades.

After the clearance was completed, the next step was to explore the electromagnetic signal just now, and the collectors never forgot their task from beginning to end.

Seize the opportunity, take advantage of the gap where the fish-like creature jumped out of the river, stuck in mid-air, the tentacles ejected like lightning, and then with a swing, the fish-like creature slapped onto the shore, and with a few quick strokes, it slapped onto the fungus carpet on the ground.

The familiar radio signal reappeared

"Finally let us find it."

"But it doesn't seem to be what we thought."

"Don't worry so much, find those guys, and all problems will be solved."

Yes, as long as you find those people who tossed all this, if you have any questions, you can just ask them directly when the time comes, and perpetual thinks so. 11
