In the Earth, Tibet, Xishabangma Peak, IA Headquarters, and the Interstellar Immigration Team Command Center, the giant display screen is playing the scene taken back by the robot on Europa.

"I'm old, these pictures look so depressing, and I'm suffering from deep-sea phobia."

Durunik was sitting in the same row with Hatano, staring at the screen with his eyes hooked. The deep sea on the picture seemed dark and terrifying, making people involuntarily create a horror that was deeply trapped in it and could not escape.

"I'm not young anymore, but I'm still like a young man!"

Yuan Shichen picked up the tea on the table next to the seat and joked.

"Do you think there are alien life in Europa's under-ice ocean world?"

Durunik asked in a different way.

"According to the data obtained by the investigation of the robot, in addition to a large number of organic molecules, different concentrations of sodium chloride, magnesium chloride, sodium sulfate and magnesium sulfate were found in the upper water bodies of the salt lake in the Europa ocean. With the existence of these substances, at least bacteria can use them to carry out life activities." Yuan Shichen replied.

"So, do you believe in the existence of life?"

"Yes!" Harashi Kazuchen nodded in agreement, "In addition to the salt lake, there are many volcanoes on the seabed of Europa. There, you should gain something to explore the robots."

"Thermal spring ecosystem?" Durunik thought, "It is indeed the place where life is most likely to exist."

On Europa, 630 million kilometers away from the earth, the intense exploration work continues.

"The investigation robot has dropped 50 kilometers below sea level!"

"It's incredible. If the water pressure of 50,000 meters on the earth is 50,000 meters deep, not to mention the investigation robot, even the most powerful tank in the world should have been crushed."

"Robots No. 8, No. 19, No. 67, and No. 92 are about to reach the bottom of the salt lake. Be prepared to collect sediment samples from the bottom of the salt lake!"

"I don't know if there will be alien creatures at the bottom of the salt lake."

Scientists gradually entered a state of tension, with all their expressions of anticipation.

"Oh my God!! Look, watch the video signal of robot No. 19." A scientist suddenly exclaimed, "At the bottom of the salt lake, there is a light!!"

Other scientists quickly surrounded him.

There is a faint light at the bottom of the salt lake, which of course would not be a lamp. Perhaps it is the light emitted by some luminous creature, or it may be the light emitted by the oxidation combustion of minerals under the sea.

"No. 8 and 67, the robot detects microorganisms in the water at the bottom of the salt lake!!"

Another surprising news came!

"Look, that lamp is really a glowing creature!!"

"Is it a mochi fish? Or a luminous jellyfish!" A scientist immediately thought of several creatures that appeared in the deep sea of ​​the earth.

"None are not!!"

"It's shaped like a tubeworm growing on the bottom of a salt lake. Yes, it has multiple large openings at the top, and it's this opening that is glowing."

"This is a very low-level creature, and it should feed on the microorganisms at the bottom of the salt lake. Maybe its light is to attract the surrounding microorganisms."

Scientists have made their own guesses.

"There are ones and twos, and there must be threes. There may be other living organisms around. Please search carefully."

"Look at me dig it up with a lamp and come back to study it."

The scientists enthusiastically controlled the investigation robot and wandered around quickly.

Sure enough, more and more living organisms are discovered by robots. However, most living organisms are very low-level creatures, and there are even some suspected living organisms that do not have cell structures.

"At least 10 prokaryotic microorganisms similar to actinomycetes, spirochetes, were found."

"Robot No. 92 discovered a eukaryotic single-celled organism. From a morphological perspective, it looked like a primitive flagellate."

"As for the current situation, the luminous tubeworm is like the highest living organism at the bottom of the salt lake."

Scientists scan the overall structure of the "luminescent tubeworm" and then present its form with the help of a computer system.

The whole is smooth cylindrical, soft leathery, and the front end is specialized into a funnel-shaped tentacle crown, which is attached to rocks or sediments. The length varies from 50 to 80 cm. Analyzing its shape, it is inferred that it relies on the funnel-shaped tentacle crown to attract and filter prokaryotic microorganisms and eukaryotic single-cell organisms at the bottom of the salt lake for life.

"Is it really because the environment is too harsh, so the creatures on Europa are so low-level and so primitive?"

"Can't you find an alien fish and shrimp?" the scientists joked.

In natural environment, the evolution of organisms is an extremely long process, and it takes hundreds of millions of years to calculate.

Life on Earth evolved from the most primitive, cell-free structure state to prokaryotes with cell structures, from prokaryotes to eukaryotic single-celled organisms, and then developed in different directions, and the fungal world, plant world and animal world emerged.

Among them, the plant world has evolved from algae to naked ferns to ferns, gymnosperms, and finally angiosperms. The animal world has evolved from primitive flagellates to multicellular animals, from primitive multicellular animals to chords, and then advanced chords - vertebrates.

Fish in vertebrates evolved to amphibians and then to reptiles, and differentiated mammals and birds. One of the mammals further developed into higher intelligent creatures, which led to the emergence of humans who dominate the earth's civilization today!

Therefore, it will take an extremely long time for Europa to evolve into a smart creature. And don’t forget that Europa’s natural environment is simply terrible compared to the earth.

"First study some microorganisms and luminescent tubeworms. Let's see what their cell structure looks like."

Subsequently, the scientists operated the No. 67 inspection robot to collect the "luminescent tubeworm" samples and immediately started returning. Other robots continued to stay in the Salt Lake area for investigation.

At the same time, the investigation robot outside the Salt Lake has also dived to a location below 70 kilometers of sea level.

"The current average water temperature is 16.8 degrees Celsius, and the water pressure is 9.28*10^7 Pa."

"The temperature is starting to rise again!"

"And, a large amount of sulfide was found in the water sample, ch4. There is likely a volcano or a hot spring below."

"Pay attention to controlling the dive speed. It is expected that if you go deeper by 20 kilometers, you will be close to the robot's pressure tolerance limit!"
