The Western Space Center in Banchang Town, Chen Nuo hurried back here as soon as he came back.

This time, a total of three satellites were built, and all three satellites were successfully launched into the sky.

The performance of the satellite was very good, and Blue Star quickly restored basic communication, and Chen Nuo and Muzi of Tianyan also got in touch again.

But three satellites bring two pieces of bad news.

First of all, the last remaining satellite of the civilized world was examined, and it was found that it was already riddled with holes. The damage to a satellite is not a physical damage, but rather the failure of the electronic components on it under the action of a certain energy.

Muzi analyzed that it may have been the damage caused by the attack of the last foreign civilization.

And that's not even the worst news, the most nostalgic news comes from the blue star panorama taken by satellite.

Luo Miao pointed to the large screen projected by the virtual and said: "There is an abnormality in the northern and southern seas - the pH of the sea water is abnormal. ”

The town of Itakura is located inland, and there is still some distance from the coastline. So if it weren't for satellite monitoring, people in the community wouldn't have been able to detect anomalies in the seawater.

"At present, the average pH of the sea (translated from the expression of blue star) is around 5, and the lowest place is between 2.5 and 3...... Luo Miao said, "I don't know the reason yet." ”

"Is this the case in several major seas?" Chen Nuo couldn't help frowning, the last time he returned to the Blue Star World, Bancang Town, he had experienced several severe acid rains. It is normal for there to be acid rain in the last days, after all, it takes tens of hundreds of years for radiation and explosion dust in the atmosphere to completely settle.

It was a few days of acid rain some time ago, so it wasn't normal.

Now the reason has been found, the ocean of Blue Star World has become acidic, and the pH value is quite low, 2.5 to 3 (the pH value of stomach acid is about this level when people eat), which is enough to destroy all marine life.

Chen Nuo would not be naïve enough to think that the sulfuric acid plant near the ocean had caused the acidity of the ocean, and now the acidic place was not one or a certain sea surface, but the ocean that spread throughout the Blue Star World.

What will be the effect of the ocean's acidic appearance on the world of Blue Star?

It will destroy the already fragile ecological environment of the Blue Star, and the hope of the Blue Star people to rebuild civilization will be dashed again.

If the basic ecological environment of Blue Star is significantly changed, the climate, lakes and rivers will become acidic, and most plants and microorganisms will not be able to survive.

This cycle of change may be a year or several years, but the only result is the complete destruction of the Blue Star ecosystem.

In the future, there may be lower microorganisms that will be able to survive, but humans will certainly not be able to survive.

"Go to the beach!" Chen Nuo said that the cause must now be investigated.

The sky car is ready, the drone is flying, and everyone heads to the beach.

After the spore blocking breeding program, the greenskins have died on a large scale, and now pose no threat to the Bluestar.

And the giant devices that stayed in the blue starry sky, although they were still suspended in the air, also stopped running.

This world is very wonderful, many things are connected in the underworld, with the current cognition of the blue star people, they can't understand where the green-skinned monsters come from, but they have no mind, whether their actions on the earth rely on instinct or are constantly receiving signals from outside the earth.

1,000 kilometers away, the nearest seaside to the town of Itakura.

The sky car stopped on the beach, and Chen Nuo and others put on protective clothing and got out of the car.

The car is not designed to prevent strong acids, and the appearance of the metal does not perform well in the humid and acidic air, and some exposed parts appear to be corroded black spots.

Seeing this situation, Luo Miao had to let the sky car leave first and find a place with weak acidity to standby.

The crowd walked on the slimy sand and communicated with the IICE device.

Luo Miao: "The air humidity is 95%, and the pH value is 5.3. ”

Luo Miao read the data of the device, reading word by word.

Chen Nuo looked at the endless sea, the sea water was not turquoise or green, but yellow-green, which is the color of the interaction between acidic substances and positive minerals in the ocean.

There is no life at all, there are no seabirds in space, and the waters are calm.

This situation is like an alien world.

Chen Nuo said: "Sampling. ”

The staff used equipment to take samples in seawater and test, and the pH value was 2.3, which is strongly acidic!

I also used a drone to take samples 100 kilometers away from the ocean, and the PH value was only 1.9!

"How so!" Feng Ran said: "Even if all the sulfuric acid of the entire Blue Star is poured into the sea, this situation will not occur!" ”

"The situation in the other oceans may not be much better, and the ocean system has collapsed." Luo Miao's face was very ugly.

The Blue Star people are full of disasters and difficulties, from despair to hope and from hope to despair.

As soon as the ocean system collapses, the Blue Star ecosystem will absolutely collapse, which is quite a blow to the survivors who are bent on rebuilding the Blue Star World.

"Muzi, can you call up the last satellite image before the satellite fails?"

Muzi sent the last satellite images before the satellite failed to Chen Nuo, and helped Chen Nuo analyze: "The problem of ocean acidification should start from the day we stopped the ships of foreign civilizations......

"What do you mean?" Chen Nuo was shocked.

"The invasion has not gone away, and it is recommended that the seawater be taken to a laboratory for testing. Extra-civilizations should change the ecological environment of Blue Star and create an ecological environment that belongs to them. ”

Chen Nuo had a bad premonition in his heart, from the green-skinned monster to the extra-triage resource vehicle suspended in the air, to the attack of the extra-vein vehicle some time ago, and now to the acid ocean.

All non-going may be set by foreign civilizations, and they are pushed forward step by step.

It's just that because the Earth is too far away, they don't know that the Blue Star People still exist, and they don't know that the Greenskin Monster is on the verge of extinction.

They continue to push their own plans, and perhaps lowering the pH level of the Bluestar Group as a whole is also part of their plan.

Sure enough, Mu Zi said his inference, which was the same as Chen Nuo's conjecture.

The crowd fell into an ice cellar.

The greenskin's feces are relatively acidic, and perhaps the acidic world is suitable for the survival of invaders.

Luo Miao breathed heavily, panicking in her heart.

Is Blue Star finished?

Feng Ran dived the small robot into the sea, and there was a dead silence......

The coral reefs are all dead, the marine plants are withering, and there is no life in the murky waters.

Luo Miao said: "How can we restore the sea water to normal, the ocean area is three-quarters of the area of the blue star!" ”

Feng Ran's robot was finally buried in the sea due to acidosis of parts, and it couldn't get up again.

Chen Nuo's face was very bad, and he said, "Take a sample, go back and analyze." Feng Ran, let the drone go to other sea areas to see the situation. ”

Faced with a huge area of the ocean, Chen Nuoyi really couldn't think of a way, but there must be a reason why the ocean became sour.
