Plant science is more difficult than physical science, and it is difficult to achieve results in a short period of time, according to the normal evolutionary process, Pandora Planet still has at least 100 million years to go before it can independently produce plant civilization. Pen, fun, and www.biquge.info

And the premise is that the Na'vi people must disappear on the planet Pandora, plant civilization is a plant-led civilization in the final analysis, the Na'vi people are not plants, the congenital conditions are missing, and Xue Chen's lack of confidence in their development of plant civilization is understandable.

And as a native of the earth, even if he does not belong to this plane, Xue Chen will never do anything that will cause great harm to human beings, and Eva once proposed to control the technology of human beings when communicating with him.

Humans are now free to fly into space, how to control it?

If you want to control it, you can only push it to rebuild, and to tear it down is to destroy.

Xue Chen categorically rejected this request, and instead adopted the method of negotiating with humans, he wanted to let the humans themselves retreat.

Sent to Pandora by the United Earth Government, former U.S. Foreign Minister Douglas, a white man in his fifties who benefited from biotechnology, looked very young, about the same as a thirty-year-old.

Douglas saw Noam, Jack, and Natilly coming with a Na'vi man in their arms, and immediately smiled: "On behalf of the Earth Government, Douglas thanks the Guardian for his help. ”

The help he mentioned was the technology on the spaceship, Xue Chen gave some to the earth to improve the problem of energy shortage on the earth, Xue Chen nodded, and said kindly: "Mr. Douglas, the earth is also my home, a little help, not enough to worry about." ”

Douglas has been on the planet Pandora for two months, and some news has come out, he understands that the body of the guardian can be converted between Na'vi and humans, and he is listening to the meaning of the guardian, has he been on Earth?

Thinking of this, Douglas said happily: "Has the guardian ever been to Earth?" ”

Xue Chen understood that Douglas was only enthusiastic and deliberately flattered, just worried that the spacecraft would launch a war against him, and asking this question was also to shorten the distance between the two, and immediately said: "I've been there, I have been on Earth for many years, and I remember the things there very well."

Jack, Natilly and the others on the side didn't think that Xue Chen had really stayed on the earth, so it was understandable that he was a human before, and listening to his tone, I was afraid that the stay time was not short.

As a combination of life on Earth and Pandora, Jack naturally hoped that the two families would be safe, so he said: "Mr. Douglas, Pandora and the Earth are both home guards, and war is not the choice we should have. ”

To be honest, before the appearance of spaceships, the earthlings knew very little about the planet Pandora, and the government had no intention of developing Pandora, after all, the road was too far away, a round trip took 12 years, and the contradictions within the earth had not yet been dealt with, so it was almost impossible to wage war against Pandora.

But since people have already come in a spaceship, whether you have an idea or not, you have to give an explanation, so Douglas came.

Jack's words, Douglas agreed, saying, "The Earth government also wants to keep peace with the Na'vi and will not start a war. ”

Xue Chen laughed and said, "The danger of the vast universe is far beyond your imagination, if humans and Na'vi people can help each other, the chances of survival will be greater." ”

This sentence, Xue Chen only vaguely mentioned that according to the information provided by Babata, any civilization in the universe will escape from the home planet and wander the universe when it reaches a certain stage of development, and the most important reason is resources.

The depletion of resources will lead to a series of chain reactions, frequent earthquakes, climate change, air pollution, etc., once the civilization can not make a breakthrough in the energy problem, then wandering is inevitable, in Xue Chen's view, the earth in this plane has signs of energy depletion, if there is no energy technology support for him, let alone a thousand years, human beings will definitely wander.

But with Pandora, it is different, the biggest advantage of plant civilization is that energy can be continuously generated, and its disadvantage is that in the final stage of the development of plant civilization, a highly intelligent plant will definitely appear to replace the entire planet, and then destroy it.

However, for the planet Pandora, which has Eva, there is little to worry about.

Greed is the nature of human beings, and the humility shown by Douglas at this time is because human beings currently have no arrogant bargaining chips, but fifty years? A hundred years? But I don't dare to guarantee it.

Xue Chen's words, Douglas deeply agreed, the purpose of his trip is to explore Pandora's reality on the one hand, to convey the friendliness of the earth on the other hand, and on the other hand, to obtain more technology from Pandora.

As for the war, what he had seen and heard in the past two months had left Douglas with no idea of war.

Xue Chen is very satisfied with Douglas's attitude, so that at least he has an explanation to Eva, with the leading degree of the spaceship, I believe that in 100 years, human beings will not dare to go beyond it, and there may be normal trade exchanges in 200 years.

As for the back, it is up to the Na'vi people themselves, and what they should have given has been given anyway.

With this in mind, Xue Chen took Douglas, Jack, Natilly and others to see the research progress of plant science and technology, and also met Dr. Grace.

When Jack carried Dr. Grace under the Soul Tree, Grace was already in a state of suspended animation, and her injuries were not serious, and it was more than enough for humans to rescue her when the medical facilities were complete.

But in the environment at that time, how could there be perfect medical equipment, coupled with Eva's prejudice against humans, with Grace's identity, Eva could not save her, unless it was a leader like Jack who had the aura of a protagonist and the future Na'vi.

Xue Chen has been waiting for this Grace for a long time, since he has agreed to Eva's conditions, then he needs enough scientific researchers, as the most qualified scientist on the planet Pandora, Xue Chen has no reason to give up on her, not to mention that saving her is just a gesture.

Therefore, when Eva's rescue failed, Xue Chen only used a little water of life to save Grace's life.

Come to the laboratory of plant civilization.

With the deepening of research, the original small laboratory was no longer enough, and an ecological experiment shed with an area of more than 10 million square meters was rebuilt.

There are nearly 10,000 species of plants in the shed, including many attacking human-eating plants.

Douglas was entering the laboratory of plant civilization for the first time, and it was really an eye-opener, especially when he saw that there were plants that could convert absorbed sunlight and carbon dioxide into a solid energy, and he was even more speechless.

This is simply equivalent to an infinite source of energy, and if the earth had this kind of plant, there would not be frequent wars.

Good things can also easily lead to evil, and Douglas can't help but have a demonic voice in his head, tempting him to obtain the plant by any means necessary.

Of course, he dared to think that Jack and Natilly had clearly told him that these plants were still in the research stage, and once they actually entered Pandora, they would inevitably cause damage to Pandora's ecosystem.

If you really want to use it on a large scale, let alone 100 years.

Seeing the shocking plants, the large-scale armed robots, and the protection of thousands of creatures in an instant, Douglas was really convinced, he understood that before humans mastered the space jumping technology, vainly trying to invade Pandora was killing himself.

Soon, Douglas used the communication system on the spacecraft to get in touch with the earth, and he was able to get in touch smoothly, thanks to a high-tech satellite left by Xue Chen when he went to the earth, otherwise with the technology of the earth, it would be difficult for Xue Chen to get in touch quickly.

When Douglas reported the content and conditions of the meeting with Xue Chen to the coalition government, the other side agreed to sign a peace treaty without any hesitation.

Regardless of whether this treaty is true or not, Xue Chen's promise to Eva is completed.

Eva also has to fulfill her last promise.
