Perpetual They stay briefly in front of a river left by the towering peaks in the center of the floating island. They need to be recharged. This river is not water, but liquid hydrogen. Collectors can directly fight here. The energy consumed is fully supplemented, as long as a little bit of chemical synthesis skills are used.

In order to replenish, the egg-shaped organism is temporarily unable to move, which makes some collectors feel bored. They try to reach into the liquid hydrogen river with their tentacles. When they are fished out, the part of the tentacles that have penetrated into the liquid hydrogen is no longer visible. , Disappeared in the vast icy river.

"what are you doing?"

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

"You are wasting resources. We have limited material."

"It's okay, this resource can be added back at once. This kind of river is very interesting. Would you like to arrange some on it after returning to Ming?"

"Waste, inefficiency, dismissed."

"That's right, the liquid hydrogen that loses pressure just flows out like this, it's too wasteful."

"You say that...it is true."

After thinking about it, the collector gave up the idea of ​​adding some decorative scenery to Min, but his attention did not move away from the liquid hydrogen river, because some small figures rushing out of the river attracted its attention.

Suddenly, a cold light flashed by, the speed is unimaginable, the tentacles of the egg-shaped creature accurately penetrated the small creature that had just jumped out of the low-temperature river, and pulled back to observe.

This creature is very similar to fish, both have the same fusiform appearance, which minimizes their resistance in the liquid, relying on a powerful tail as the driving engine in the river, allowing them to move and jump out of the river. The river surface provides the foundation.

A spine extends from the skull to the end of the tail, and muscle tissue is mainly distributed around the back spine to give them strong power support.

Not only the appearance, but also the action are quite similar to the torpedo. For example, now, I am constantly struggling in vain on the single-molecule blade that penetrates my own...

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

"What's the matter? The aliens and the creatures on their home planets. Isn't it this kind of biological structure? It's not surprising, but the design is very interesting. It is the first time I have seen a creature with a battery structure."

The body fluids of these fish-like organisms are acidic corrosive liquids, and combined with their bone structure, they become a living battery. It moves back and forth and uses the large temperature difference to make the metal bones generate electrical energy. After the electrical energy is generated, it will be absorbed and stored by the battery structure.

As for the use of these electric energy, reality soon informed these collectors of sustainability with facts.

Perpetually, they once again saw the flying creatures that appeared in the sky. They came to prey on fish-like creatures, and their fangs and claws swept across the liquid hydrogen river at high speed and carefully, and grabbed the fish-like creatures that had just jumped out of the river.

Unlike the collectors, due to the shape, the flying creatures did not cause much damage to the fish-like creatures at first, which gave the fish-like creatures a chance, and they would not be eaten obediently.

A crackling electric shock sounded, and the flying creatures froze and fell into the liquid hydrogen river together with the fish-like creatures. The result was obvious. The flying creatures were completely frozen by the low temperature, and when they were washed by the river, they shattered into a pile. The ice scum of ice followed the same footsteps as the tentacle that a collector had just sacrificed.

Fish-like organisms survived because of their adaptation to the environment of the liquid hydrogen river.

Of course, everything is not going smoothly. Some flying creatures glide and don't fall into the liquid hydrogen river. Then the result is another matter.

Occasionally, there will be a situation where both sides are injured. Flying creatures are either dead or maimed on the branches on both sides of the river bank hit by gliding. Fish-like creatures are thrown onto the shore of the principle of liquid hydrogen, and the futile jumps gradually towards life. end.

Life is like this. Living in the world in the fight and fighting, there is only one way to die. This is nothing. Long ago, the collectors understood this principle deeply and did not intend to intervene.

However, the latter things made them change their minds...

The fish-like creatures on the ground feel that death is approaching. They don’t want to die, but their sesame-sized brains can’t think of a solution at all. In their cognition, death and the enemy are linked, so death’s proximity means death. The enemy has not been knocked back, because the electric energy released is not enough. The fish creatures of this type will continue to release electric energy during the process of jumping until the electric energy is completely exhausted and life comes to an end.

When the body of a fish-like creature touched a mesh blanket on the ground, the collectors obviously caught a familiar electromagnetic wave signal. This electromagnetic wave signal had no readable information, but the frequency band was exactly what the collectors caught when they were in space. That electromagnetic wave frequency band arrived!

"... Changed my mind and kill all the people who got in the way."

"Understand, start targeting multiple targets."

The flying creature's hearing organs keenly caught bursts of air breaking sound, as if something was moving at high speed, but they didn't catch any unknown target from high in the sky, 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. The flying creatures were pierced by the tentacles, and the single-molecule blade cut them into eight pieces without resistance like cutting tofu.

Of course, flying creatures can't find anything, because the attack is launched from the ground. What can be found from the sky?

After a while, the battle of the collectors ended. No, it cannot be said to be a battle. It should be said that the efficient slaughter is over. Except for a few flying creatures that are far away, most of them have become single-molecular-edged fallen souls.

The clearing is completed~lightnovelpub.net~ The next step is to explore the electromagnetic wave signal just now. Collectors never forget their mission from start to finish.

Seizing the right time, taking advantage of the fish-like creatures jumping out of the river and staying in the mid-air gap, the tentacles ejected like lightning, and then with a swing, the fish-like creatures were photographed on the shore. After a few quick strokes, the shot was taken. Those reticulated fungus blankets on the ground.

The familiar radio signal appears again!

"Finally let us find it."

"But this seems a bit different from what we thought..."

"Don't worry about so much, find those guys and solve all problems."

Yes, as long as you find the comrades who have tossed all of this, if you have any questions, then you can just ask them to understand. This is how we think about sustainability.
