"That is... a tsunami?!"

　　 "Find a way to hide!"

　　 "Drilling! Drilling!"

　　 Adjust the convexity of the pupils so that the eyes have telescope-like effects, extending vision to extremely far places, and the collectors can see the true face of the white line at the edge of the sky, which is the super giant tsunami on this planet.

　　 Through several bio-radar ranging, the collectors roughly calculated the speed of the tsunami-1.3km/s!

　　 What is this concept? This is equivalent to a water wall composed of millions of tons of liquid water rushing towards you at a speed of Mach 3 on the surface of the planet!

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

　　 The collectors are extremely convinced that once they are involved in the tsunami, even with their tenacious vitality, whether they can survive or not, they can only rely on their fate, expecting the illusory luck, so they will be so panicked.

　　 The body is flat like a canvas biological body, using its tentacles to continuously draw the bottom of the water, the coarse sand and gravel at the bottom are cut away, exposing the whole rock at the lower level.

　　 The local genes of the organism are rapidly modified and changed, so that a sharp single-molecule blade is formed around the edge of the flat biological body. As long as electric energy is injected, the single-molecule-level cutting ability can be achieved.

With the metal-hydrogen battery as a backing, the collectors will not worry about the consumption of electric energy. They use single molecule cutting to quickly cut a small gap from the rocky surface. Cut down and hide yourself in it.

　　After the collectors hid themselves in the underground crevice for a period of time in advance, the vibration they felt became stronger, which also indicated that this terrifying tsunami was getting closer and closer to them.

　　 When the tsunami passed above the collectors, observing the top through the gap, the originally clear water body became turbid, and the supersonic water flow quickly passed by.

The collector hiding in the crevice tentatively touched an antennae with the water above. When it retracted, the antennae no longer existed, and only a neat section remained, as if it had been hit by some kind of extremely sharp blade. The wound left after cutting,

This wound fully explains what is on top of the collector. It just looks like water. It can no longer be regarded as water. It is a knife made of water. It is dense and sharp. Get involved in it, and don't even think about surviving a single cell.

　　 "It's terrible, but why is there such a tsunami? I have never heard of a planet whose tsunami can reach three times the speed of sound."

　　 Fortunately, the radio that composes the channel has not been interfered, and the water body does not have the ability to interfere with communication. The collectors who have had a lingering heart sigh in the channel.

　　 Its inquiry was quickly answered by the same clan, and some collectors have already analyzed the cause of the formation of this supersonic tsunami.

"That's because there is a black hole. The gravitational force of the black hole makes the tidal force on the surface of this terrestrial planet extremely terrifying. Every ebb and flow of the long tide is such a terrifying tsunami, and even the rotation of the planet itself is synchronized with the revolution, because Tidal force lock-in caused by the black hole's gravity."

　　 "I understand why the terrain of this planet is so flat. The powerful water changes eroded and worn the towering mountains on the planet's surface, just like sanding an iron pestle with sandpaper, and grinding the iron pestle into fine needles."

　　 "The black hole relies on the tidal force caused by gravity to round the planet's surface... It's really fun."

　　 Although it is clear that a black hole is a dead thing, it is not the same as Min, but after encountering this kind of thing, it is inevitable that some collectors will think like this.

　　 The information exchanged between the collectors, summed up, quickly deduced the status of this terrestrial planet orbiting the black hole, and the deduction is not very detailed, but the general information has basically been deduced.

　　 Among the few collectors, one of the collectors raised a question during the conversation.

　　 "It's strange, I don't understand why this happens."

　　 "What's the strange thing?"

　　 Hearing the questions of the same family in the channel, the collector of the question truthfully explained the question that puzzled him.

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

　　 The emergence of this question caused a brief silence in the channel. Several other collectors were thinking about the answer to this question, trying to explain this phenomenon.

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

　　 "It is true. Those high-speed water bodies are a good sander. Small gravel will be sanded into coarse sand, and coarse sand will be sanded into fine sand again..."

　　 The current speed of Mach 3, this kind of water body change speed, but no fine sand is formed, this is a very unusual matter, and the conditions for formation are obviously sufficient.

　　 After a bit of entanglement, the collectors gave up thinking.

　　 Mainly whether this detailed problem can be answered, it doesn't matter to them, and there are tasks in the body, it is not good if the task is affected by the excessive study of the details.

　　 "Too much waste of brain and energy is undesirable. Everyone should buy time to rest, wait for the tsunami to pass, and immediately rush to the signal source. After confirming the situation there, leave this dangerous planet as soon as possible."

　　"Understood~lightnovelpub.net~ The tsunami came quickly and left quickly. After a few hours, the tsunami that reached Mach 3 quickly left the collectors completely.

　　 Several collectors hiding in the ground got out of the cracks in the stone one after another, and the first thing they did when they got out was to watch the surrounding environment very vigilantly to confirm whether there was a dangerous situation.

　　 After the confirmation, the tight nerves relaxed slightly.

　　 "The tsunami is finally over."

　　 Among the few collectors, some collectors expressed emotion in the channel.

"Everyone act quickly. After a period of time, the tsunami will circle the planet and return to us. The tidal effect is periodic. According to the planet's revolution speed, this time interval will not be very long. Arrived at the signal source before the tsunami."

"set off!"

　　The collectors are no longer as relaxed as they were when they first landed. The tsunami allowed them to see how dangerous this planet really is.

They change their shape, by plundering the surrounding environment, they assemble themselves into simple-structured organisms, which look like small boats, or the structure of a small boat. The tail of the boat is heavier than the head, so the first half will be slightly Lift up.

After the water is sucked into the water storage tank behind the body by the biological pump, the electric energy of the metal hydrogen battery electrolyzes the water body into a hydrogen-oxygen mixed gas, and then the organism introduces it into the propulsion tank behind the stern for detonation. The collectors gallop on the water like sailfish.

　　The distance between them and the metal structure is getting closer!
