Doomsday: spore invasion, my system has no upper limit

After Ambassador Pilka left, Qiu Liangping asked, "Xiao Zheng, have you decided to take the initiative?"

Zheng Chen said: "Chairman, I think it is most important to restore our own environment."

Qiu Liangping nodded and said, "Yes, I want to go with me, no matter how the silicon-based people compete with the Galactic Alliance, as long as they don't enter the solar system."

Han Lidao: "Whether they are hostile or an alliance, it is not good for us humans anyway."

Zheng Chen said: "Our Blue Star has just restored the ozone layer, and there is still a lot of sulfide gas in the atmosphere. Except for some advanced transcendents, some ordinary people have evolved to the level of guardians, and they cannot survive outside the base, let alone restore animals and plants. gone."

Qiu Liangping said: "Then the next most important thing is to purify the atmosphere of Blue Star."

Professor Picard said: "If you use battleships alone to extract sulfide, although it can have a short-term effect, it cannot achieve a sustainable cycle."

Zheng Chen said: "It seems that Blue Star's plant oxygen production system must be restored as soon as possible."

Qiu Liangping said: "New types of sulfur-absorbing crops have begun to spread in all bases. Now that the ozone layer has recovered, the plants stored in the base can also be transplanted outside."

Professor Picard said: "The plants on land have little effect on the essence of the large airways. The most important thing is the marine algae. First of all, we should restore the marine cyanobacteria ecosystem."

"Are you from the Blue Star? How did you come to our world?" The leader suddenly spoke fluent Blue Star language.

Zheng Chenxi said: "So we can directly drive the battleship to pull?"

The surrounding water temperature is above 0 degrees. The most amazing thing is that the ocean is covered by a thick layer of ice, but there is a light source inside.

"Poseidon? Poseidon?"

See what else it contains besides water molecules.

The water layer on the surface of the planet is more than 100 kilometers thick, the top layer is a few kilometers of ice, and under the ice is a liquid ocean.

They flew to several other locations on the planet to collect more than a dozen samples.

As soon as the words fell, they saw hundreds of light spots quickly surrounding them.

Moreover, there is a thin atmosphere on the surface of the planet, and the basic component is oxygen.

This is the most water-rich planet in the solar system, much more water than the blue star.

Zheng Chen sent out a phase beam, cut off a piece of solid ice, and put it into the island-shaped subspace for Professor Picard's team to inspect.

The salt content in the Blue Star Ocean has been greatly increased, and it is no longer possible to bring back seawater with high salt content.

After coming to the planet Europa, the second satellite of Jupiter.

Immediately, I felt like diving in the blue star ocean.

When they scanned Zheng Chen, Zheng Chen also observed them carefully.

Bai Yi and Zhang Lingquan still stayed at Blue Star to assist in the defense.

After a while, these light spots became bigger and bigger, and they were less than [-] meters away.

This is due to the fact that the ice on the surface of the planet is broken down by solar particles into hydrogen and oxygen, the hydrogen flies away and the heavier oxygen stays behind.

"Mermaid? Or murloc?" Zheng Chen asked in surprise.

Zheng Chen was stunned for a moment, isn't that a myth and legend?What is a real historical event?
Professor Picard in the sub-space was ecstatic, and was recording it reluctantly for a second.

Qiu Liangping said: "Then grasp it with both hands and proceed at the same time. All the warships will start to extract the air, and the scientific research team will start to study the recovery of marine algae."

And the clothes of these creatures are clearly highly civilized species.

Unexpectedly, the other party actually spoke the Blue Star language. Could it be that they have the same ancestor as humans?
"I did come from Blue Star, what race are you, and how do you speak Blue Star language?"

The surface of Europa is very smooth, unlike the blue star with vertical and horizontal mountains.

Since Han Lingxue's three daughters and Picard's science group were still in the subspace, these creatures only saw Zheng Chen.

Qiu Liangping said: "Okay, thank you for your hard work, Xiao Zheng, you can just make up your own mind."

"Marshal, these ice samples are very pure, with a purity of 99.999%. A small amount of impurities are some minerals, which can completely replenish the water of Blue Star." Professor Picard reported.

Zheng Chen then led Han Lingxue, Xue Wen and Li Yuzhi to leave the battleship and fly to Jupiter.

"Okay!" Zheng Chen immediately teleported himself under the ice layer several kilometers thick.

"It's not surprising. With this temperature and abundant fresh water resources, it's strange that no life appears." Zheng Chen smiled.

The dots of light they had just seen came from these harpoons.

This made Zheng Chen very surprised. Originally, he had prepared the translation function of the system to see if he could recognize it.

"Using your human language to describe it, we are the Sea Gods of Planet Europa. We have been to Blue Star many times and helped the development of mankind."

Zheng Chen's investigation this time is mainly to detect the composition of the ice layer.

"Husband, I sensed a group of intelligent life forms swimming towards us at high speed!" Han Lingxue said.

Before Zheng Chen could speak, the leader of the opponent turned the harpoon and emitted a layer of scanning light waves to scan Zheng Chen.

"General Poseidon is a historical figure 5 years ago. He once led the Sea Gods to help humans deal with the global flood of the Blue Star, and forged a deep friendship with humans in the primitive society of the Blue Star at that time."

These creatures hold weapons in their hands that look like harpoons, but the prongs emit light balls of concentrated ion energy.

What came into view was a huge world of ice and snow.

What Blue Star needs is pure fresh water, because what the solar wind blows away is pure water vapor.

Zheng Chen said: "Chairman, I want to go to Europa and inspect the ice layer there so that it can be used to restore the water lost by the blue star."

There is a possibility of launching at any time.

……

The speed is very fast, faster than any fish in the blue star ocean.

This is because they also saw clearly that the visitors were a group of creatures that looked like fish and people.

Professor Pickard said: "Because the water freezes and floats on top of it, and impurities can sink into the liquid water, you're better off going into the ocean under the ice to get some water samples."

This is a momentous moment, one that not only unlocks the early history of humanity, but also forges a powerful ally.

Zheng Chen said: "It turns out that you and humans have had a deep friendship for a long time, but we have developed to the point where we still don't know that there is life on Europa!"

"Early humans couldn't accept the fact of extraterrestrial life. We can only say that we are Sea Gods to dispel the doubts of the smart blue stars. It seems that you have evolved to the point of space travel now."

Zheng Chen said: "Actually, I came here to ask for help. Blue Star was attacked by alien silicon-based people 30 years ago. Now Blue Star is almost on the verge of Martianization."

"As the first human being to visit us, please enter our city and officially start a diplomatic visit. We will do our best to help you."
