Planting communities.

People in the community are still excited about yesterday's harvest.

Grains, fruits, vegetables, nutrients and modern planting techniques have brought enough food to everyone.

If it weren't for the barren environment outside the community and the dilapidated city in the distance, the residents of the community would still wonder if they were still living in a civilized era.

"If we want food and shelter, as long as we work hard, we will definitely be able to rebuild civilization."

Somewhere in the planting community, the foreman said to the workers.

Everyone is full of hope for the future, but they don't know that the crisis has come.

After Chen Nuo and his entourage returned from the beach, they went straight to the laboratory, and the seawater had to be tested immediately.

The technician turned out the test tube in Feng Ran's hand and immediately began the test.

Half an hour later, the experimenter whispered a few words to Feng Ran with a grim face.

Luo Miao said: "If there is anything, just say it." ”

The experimenter did not dare to disobey Luo Miao's order, and said, "Please follow me in." ”

The virtual projection shows the pattern of seawater under a microscope.

The experimenter explained: "There are various acid ions mixed in seawater, such as sulfate, nitrate, hydrosulfate, phosphate, etc., among which nitrate is the most, which is the root cause of the acidity of seawater. Acid ions react with various minerals in seawater to form acidic minerals, so the eye color of seawater is yellow-green. ”

The experimenter smiled wryly: "Now we can compare seawater to a huge acidic battery, and I think there is already ionization instability in some places." ”

This is to be expected.

"But what is the cause of the acidity of the sea?" Luo Miao asked, "It is impossible for anyone to pour all the acidic substances of the world into the sea, right?" ”

"Not really!" The experimenter said, "Look. ”

Round spots appear on the projection screen.

"What is this?" Chen Nuo leaned over and saw that the spot was actually some kind of yellow creature, with a transparent film-like substance on the outside and some small components inside.

"Unknown creature." The experimenter said: "This is a microorganism that Blue Star has never seen, although the structure has not been clearly understood, but their metabolic principle is clear." ”

The experimenter gives the basic principles on the screen.

This organism absorbs salts in seawater and various minerals in seawater, and then produces a large number of acid ions through a series of complex reactions to ensure the survival and reproduction of its own life.

"We can't say for sure now whether it's a chemical reaction or a physical reaction, and if it's a physical reaction, it involves creating elements — S, N, P, etc.," the experimenters said. These elements are present in seawater, but not in sufficient quantities to cause such a large area of acidic ocean. We tend to be living beings who create these elements non-stop. ”

The creation of the elements must involve the aggregation or release of energy.

If you use elements such as H and O in seawater to create S and P, you need to absorb energy.

Where does the energy come from? Kinetic energy in the ocean? Or solar energy?

Chen Nuo really felt that the temperature of the sea water was lower than he expected, and it was very likely that these creatures had absorbed most of the energy of the sea water.

If you use the N element in the air to synthesize N into nitrate, it is also a difficult task, and this creature actually did it.

"Probably a hybrid creature like the Greenskin." The experimenter added, "But we need to analyze it specifically. ”

The experimenter had a projection device project a third pattern showing the number of such creatures in the seawater.

"They reproduce almost all the time, and there are thousands of them in every drop of seawater."

"By what means?" Chen Nuo asked.

"Special Spore ......"

Spore......

The greenskins are also spores, and this creature is also a spores......

It is self-evident whether the two are homologous.

"Is there any way to make it die?" Chen Nuo already had the worst in his heart.

"We've used the way to destroy ordinary bacteria, and there's no way to make them die."

"What about spore blocking?" Chen Nuo proposes a way to destroy the greenskins.

"They live in the ocean, not on land. Blocking drugs are diluted in seawater and are ineffective against them, the ocean is large and now acidic, and no amount of drugs is enough. ”

Chen Nuo's heart was cold.

He walked out of the lab with a heavy heart, his heart overwhelmed.

The invasion of the Blue Star by an extra-cultural civilization is like an established procedure, what you do in the first step, what you do in the second step, and it will not change because of what happens on your Blue Star.

The procedure is mechanical and cold, and there is no room for negotiation.

Chen Nuo looked up at the sky, what is beyond the galaxy, what kind of civilization wants to kill Blue Star.

Luo Miao also came out of the laboratory, relying on Chen Nuo, everyone's hearts were panicked.

Chen Nuo hugged Luo Miao and said with relief: "No matter how difficult it is, it will pass." ”

Luo Miao nodded, and said with a firm gaze: "We won't give up." ”

"Muzi." Chen Nuo called.

"I'm here." Muzi's voice will be so soft.

"Is it possible to analyze the effects of acidic seas through satellite imagery? How much time it takes can affect the lives of the people in the community. ”

Muzi said: "It has been analyzed that Itakura Town is an inland city with its own internal circulation ecosystem, but under such a large ecology as Blue Star, it will still be affected by the ocean." Five years at the earliest, and ten years at the latest, the acidic ocean will affect the town of Banba. At that time, the land, water, and climate were no longer suitable for survival. ”

Muzi said again: "But if the rain brings those monsters in the ocean to land, no one knows what will happen. ”

Five to ten years.

Respite from Itaba.

Chen Nuo immediately made a decision, "Let the laboratory increase the research on this creature and see if there is any way to restrain it." In addition, find a way to deal with acidic water sources. ”

Chen Nuo said to Luo Miao: "The worst plan is to build a lid with cubic boron nitride (improved acid corrosion resistance) in Itakura Town, create an internal circulation inside, and preserve hope for mankind." ”

Luo Miao shook his head and said, "Five to ten years, we have time!" ”

In fact, Luo Miao regretted it a little in her heart, the Blue Star World may really not be saved, she shouldn't have selfishly left Chen Nuo's genes.

Luo Miao looked at the depths of the laboratory, Chen Nuo's child was developing in the incubator, and it would be born in a few months.

Chen Nuo looked at the dim sky, would he give up the Blue Star World?

Abandon the Blue Star World and return to Earth.

Sitting on trillions of blue star group, happy for a lifetime, no longer to pursue the relationship between blue star and the earth.

People have been in a lifetime for decades, and the whole world doesn't know about the existence of Blue Star, so why should Chen Nuo be burdened with such a heavy burden.

Chen Nuo has one last choice - if Blue Star really can't be saved, he can only find a way to let Luo Miao return to Earth with him.
