Fortunately, there is still a distance between the robot inspected on the 18th and the robot 77th.

At this time, the No. 18 robot had successfully arrived at the surface of the undersea volcano, and it was very fortunate to withstand the huge water pressure and become the last survivor.

"Quick, hurry up! Hurry up!!"

Scientists couldn't wait to start manipulating the robot to collect samples of seawater and sediments at the bottom. At the same time, the robot inspected was always vigilant and observed the surrounding situation in all aspects.

No one knows what will happen in this strange dark world under the sea, which is 110,000 meters deep, in the next second, perhaps being blown up by huge water pressure, or being attacked by strange alien creatures.

On the 18th, the robot was inspected along the trench, carefully and slowly advancing forward as if walking on thin ice.

"The water flow ahead is abnormal, and it should be where the crater under the sea is located."

"The water temperature continues to rise, and the current average water temperature is 8 degrees Celsius."

"The sulfide, ch4 content is still rising significantly. Robot No. 18 is approaching the hot spring area of ​​the crater."

"There must be a hot spring ecosystem here, and it is also likely the birthplace of Europa's life!"

Since there is only one inspection robot left and the surrounding environment is too harsh, the exploration action is progressing very slowly.

This really made everyone very worried.

"Here! Here!"

As the inspection robot on the 18th continues to approach the exit of the volcanic hot spring, a biological community that is both familiar and unfamiliar to everyone gradually appears.

Around several deep-sea hot springs explored by the No. 18 robot, there are many strange creatures living in, including living organisms similar to tube-dwelling worms, mollusks with shell-like substances, and many microorganisms of different shapes.

Even at the closest to the outlet of the volcanic hot spring, where the temperature is as high as 280 degrees Celsius, robot No. 18 has discovered an autotrophic microorganism that can obtain energy by using the sulfides emitted from the hot spring.

"It is the environment near the hot spring vent that provides the energy and matter needed for the emergence of Europa's life and subsequent continuation of life."

“The hot spring ecosystem is indeed the ideal place to nurture life.”

"Europa's oceans can indeed support life. Although the environment is harsh, microorganisms can survive tenaciously. That is to say, organisms near these hot spring vents around the world are likely to be the common ancestor of all existing organisms on Europa."

"However, we have not yet discovered a suspected high-level creature that destroyed robot No. 77. Is there not many such creatures? What kind of form is this high-level creature? Will it be a vertebrate?"

"Verpensive animals!? I think this is unlikely. Judging from the current situation, Europa wants to evolve advanced creatures like vertebrates, and there is little hope. You should know that mollusks like jellyfish or squid may also destroy robot No. 77."

Scientists expressed their opinions one after another.

By comparing horizontally with the earth, Europa's submarine ecosystem is still at the level of the Cambrian 500 million years ago on the earth.

Since the formation of the earth, geological history can be divided into the following periods: the ancient times of the Ming Dynasty (45-3.8 billion years ago), the ancient times (38-2.5 billion years ago), the Proterozoic times (25-570 million years ago), the Paleozoic times (57-245 million years ago), the Mesozoic times (245-65 million years ago), and the Cenozoic times (65 million years ago-now).

Among them, the Paleozoic period was subdivided into the Cambrian-Oddovician (570-438 million years ago), the Silurian-Devonian (438-355 million years ago), and the Carboniferous-Deridian (355-245 million years ago).

During the Cambrian period on Earth, invertebrates emerged in large numbers, including trilobites, accounting for 60% of the total animal kingdom at that time. During the Ordovician period, invertebrates of all phylums had developed completely, and the ocean showed a scene of vitality.

However, Europa is very different from the earth, that is, there is no sunlight, so there is no major organism such as algae that exist in the Proterozoic oceans in its oceans.

"Because the environment is too harsh here compared to the earth, the evolution of Europa marine organisms must be extremely slow. Perhaps in another billion years, vertebrates similar to the earth will not develop."

"In the past 438-355 million years ago, there have been two major changes in the history of earth's biological development." A senior biologist continued to elaborate his point of view. "The first change was that organisms began to leave the ocean and develop towards land. The first landing was green algae, which broke away from the constraints of the water environment and evolved into naked ferns. The second change was that invertebrates evolved into vertebrates, such as the armorless fish that appeared during the Silurian period (not real fish), and the shield-skinned fish and sprigated fish that appeared during the Devonian period, which eventually gradually evolved into overlords in the waters."

In the distant Europa, the scientific exploration team and the robots in the ocean under the ice shell are still working hard.

In the command center of the Interstellar Exploration Alliance headquarters, Harashi Chen and Durunik have also known about the latest exploration results and have received research reports on life forms from the Europa Salt Lake area.

"Since life exists under the ocean of Europa, this means that as long as the appropriate conditions are met, the birth of life in the universe is a high probability event. Human beings are not lonely in this universe! Although life forms may be very different from life on Earth, there will definitely be various life existences in habitable planets in other galaxies." Durunik said with certainty.

"There is another point. From the perspective of microstructure, the cellular structure of Europa's living organisms is completely different from that on Earth! Life is really amazing!!"

"This phenomenon can prove that the birth of Europa's life is mostly unrelated to the Creator. Perhaps Europa finally gave birth to the most primitive life system after an extremely long period of time." Hatoshi Chan inferred, "From Europa's current environment, it is almost impossible for its life system to develop rapidly without using external forces and give birth to intelligent life!"

"Unlucky Europa!! As unlucky as the earth!" Durunik sighed, "I don't know if Europa's life system can survive after a gamma-ray raid."

"We can try to preserve some of the fires of life for Europa and cultivate them in Jupiter's space city. Perhaps we can send them back to Europa in the future." said Harashi-chan.

"Haha~, then Earth civilization will become Europa's savior!" Durunik laughed happily.

Haraki looked at Durunik, patted his shoulder and smiled knowingly, "Yes, those primitive lives of Europa certainly won't know. Our conversation today determines their future!"

"Haha~" Durunik seemed to laugh even more happily.

"Europa still has a future!" Yuan Shichen stood up, turned toward the screen, and said meaningfully, "In the distant future, when the sun gradually grows larger and the temperature rises, it becomes a red giant. It will swallow Mercury and Venus, making Earth and Mars a barren rocky planet that life is not suitable for survival. And cold satellites like Europa will become an ideal and livable planet for life to survive!"
