"Is that a tsunami?!"

"Find a way to hide!"

"Drill the ground! Drill into the ground! ”

Adjusting the concave and convex pupils gave the eyes the effect of telescopes, extending their vision far away, and the collectors could see the true face of the white line at the edge of the sky, which was the planet's giant tsunami.

Through several bioradar ranging, the collectors roughly calculated the speed of the tsunami at 13ks!

What is this concept? It's the equivalent of a wall of millions of tons of liquid water rushing towards you at Mach 3 on the planet's surface!

What kind of tsunami is this, this is clearly a cannonball!

The gatherers were extremely sure that once they were caught up in the tsunami, even if they were so tenacious, whether they could survive or not could only depend on fate, counting on the illusory luck, which is why they were so panicked.

The flattened body of a creature resembling canvas constantly scratches the bottom of the water with its antennae, and the coarse sand and gravel at the bottom are cut away, revealing the whole rock at the bottom layer.

The genes of the local organisms are rapidly modified and changed, so that the edges of the flat biological body form a sharp single-molecule blade, and as long as electrical energy is injected, the single-molecule cutting ability can be realized.

Backed by metallic hydrogen batteries, the collectors will not be bothered by the consumption of electricity, and use single molecular cutting to quickly cut a small gap from the rock surface, and then the collectors will continue to cut downward while propping up the gap, hiding themselves in it.

After the gatherers hid themselves in the crevices of the ground for some time, the tremors they felt became more and more intense, which also signaled that the terrifying tsunami was getting closer to them.

As the tsunami passed above the collectors, looking through the gaps, the previously clear water became turbid, and the supersonic water rushed by.

The gatherer, hiding in the crevice, tentatively made contact with a tentacle of the water above, and when it retracted, the tentacles were gone, leaving only neat sections, as if they had been cut by some extremely sharp blade.

The wound was a good indication of what was above the gatherer, it just looked like water, but it could no longer be regarded as water, it was a knife made of water, dense and sharp, and it was caught in it, and not even a single cell could survive.

"It's scary, but why is there such a tsunami? I've never heard of a planet with a tsunami that can reach three times the speed of sound. ”

Fortunately, the radios that make up the channel were not interfered with, and the water bodies did not have the ability to interfere with communications, and the apprehensive gatherer sighed in the channel.

Its inquiries were quickly answered by its peers, and collectors have already analyzed the cause of the formation of this supersonic tsunami.

"That's because of the existence of a black hole, and the gravitational pull of the black hole makes the tidal force on the surface of this terrestrial planet extremely terrifying, and every long ebb and flow is such a terrifying tsunami, and even the rotation of the planet itself is synchronized with the revolution, because the tidal force of the black hole's gravity is locked."

"I can understand why the terrain of this planet is so flat, and the powerful changes in the water have eroded and worn away the towering mountains on the surface of the original planet, just like grinding an iron pestle with sandpaper and grinding the iron pestle into a fine needle."

"Black holes rely on the tidal force caused by gravity to polish the surface of the planet and round it."

Although it is clear that black holes are dead things, unlike twilight, it is inevitable that some collectors will think like this when they encounter this kind of thing.

The exchange of information between the collectors was summed up, and the situation of this terrestrial planet orbiting the black hole was quickly deduced, which was not very detailed, but the general information had basically been deduced.

Among the several gatherers, one of them raised a question during the conversation.

"It's strange that I don't understand why this is happening."

"What's the strange thing?"

Hearing the inquiries of the same clan in the channel, the collector who asked the question truthfully explained the questions that puzzled him.

"Such a high-speed change in the water body should form fine sand, but the surface of the planet is full of coarse sand and small gravel, and it is impossible to understand the reason for this formation."

This question caused a brief silence in the channel, and several other collectors pondered the answer to the question, trying to explain the phenomenon.

But in the end, they found that there was no way to explain it.

"That's true, those high-speed moving bodies of water are a good grinder, and the small gravel will be polished into coarse sand, and the coarse sand will be polished into fine sand"

The speed of the water flow in Mach 3, the speed at which the water body changes, but does not form fine sand, is a very unusual thing, and the conditions for its formation are very sufficient.

After some struggle, the gatherers gave up thinking.

The main thing is whether this detail can be answered or not, it doesn't matter much to them, and there is a task in them, and it is not good to transition to delve into the details and cause the task to be affected.

"It's not advisable to waste too much brain power and energy, everyone should first try to take a break for a while, wait for the tsunami to pass, immediately rush to the signal source, confirm the situation there, and leave this dangerous planet as soon as possible."

"Understood."

The tsunami came and went quickly, and after about a few hours, the tsunami reaching Mach 3 left completely above the collectors.

Several gatherers hiding underground have emerged from the cracks in the rocks, and the first thing they do is to be very vigilant to observe their surroundings to see if there is any danger.

After confirmation, the tense nerves relaxed slightly.

"That tsunami is finally over."

Among the several collectors, some collectors sighed in the channel.

"Everyone move quickly, after a while, the tsunami will circle the planet and come back to us, the tidal effect is periodic, according to the speed of the planet's revolution, this time will not be very long, all hurry up and act, and strive to reach the signal source before the next tsunami arrives."

"Let's go!"

The gatherers were no longer as relaxed as they had been when they first landed, and the tsunami had shown them just how dangerous the planet really was.

They change their form and by plundering the material of their surroundings, they assemble themselves into simple organisms that resemble a boat, or the structure of a small boat, with a tail that is heavier than the head, so that the front half is slightly raised.

After the water is sucked into the storage tank behind the body using a biological pump, the electricity from the metal hydrogen battery electrolyzes the water into a hydro-oxygen mixture, and then the organism directs it into a propulsion tank behind the stern of the ship for detonation, in exchange for extreme speed, and the collectors gallop on the water like sailfish.

The distance between them and the metal structure is rapidly closing!
