Chapter 237

Zhang Yuan and Zhao Qingfeng looked at each other and carefully pondered the unique physiological phenomena brought by different environments.

Oxygen is a necessity for human beings. A lot of energy brought by aerobic breathing moistens every cell in the human body. Without oxygen, human beings will suffocate and die in a short time.

But in the eyes of many biology experts, oxygen is also a chronic poison!

A harmful substance called "oxygen free radical" produced by human respiration can cause biofilm system damage and intracellular oxidative phosphorylation disorder. It is a direct participant in human disease, aging and death, and is very harmful to human health and longevity.

The Gliese people's circulatory system does not need the participation of oxygen, and naturally they will live longer

Then this group of biologists became fanatical and began to make a lot of speeches about the conversion of ATP, CP and ADP in the "energy core"... Ichiro Yamamoto began to take the opportunity to call for the replacement of the current aerobic respiratory system with artificial blood and artificial respiratory system. "The most intuitive benefit is that it can delay the speed of cell aging, Achieve higher life "!

Anyway, Zhang Yuan understood that because of the lack of energy brought by anaerobic breathing, these Gliese must sleep for a long time.

Zhao Jian, sitting around, sighed: "so, not only typhoons, but also this way of dormancy evolved from the primitive, which makes them prefer a narrow and accessible environment. At least it consumes less physical energy... And it's safe and reliable. Don't worry about the collapse and bury yourself alive! "

Then there is no way. These high-level human beings can only bear to wait.

After about 12 days, the Gliese finally regained consciousness. The leader, ganyaduo, said: "thanks to the generous human civilization, this sleep was very comfortable. Please forgive us for our work and rest. I know that some civilizations do not sleep. I wonder what your work and rest are like? "

Of course, humans don't care about this little thing

This long overdue diplomatic event was quite grand. First, several civilized diplomats led this group of Gliese to visit some areas of the earth times, including industrial area, agricultural area and living area.

Of course, it is only a part.

In fact, there is a faint sense of deterrence. We should let the other party know something, but we can't let the other party know too much. This fuzzy state of half knowledge and half solution is the most favorable for human beings.

Next, these Gliese diplomats sat in the same conference room with the high-level human beings and began face-to-face negotiations.

The leader named ganyaduo first asked, "first of all, I want to know the specific history of your civilization."

"Why do you think of coming to our galaxy from the distant solar system more than 20 light-years away? From an economic point of view, there is nothing to map... We don't have any special material resources here. Is it because of the population explosion that the whole galaxy can't live? "

This issue is quite important and involves the issue of human ideology.

After some consideration, Captain Zhao replied: "our parent galaxy is not in a population explosion, but in a stable state where the population stops growing."

"The purpose of coming here is not to colonize and conquer, but mainly to explore and discover."

"The great man of our civilization believes that when a civilization develops to a certain extent, it will spontaneously stagnate. In order to avoid the recession caused by this stagnation, we must isolate space and time and learn from the past development process in order to walk out of a new road... "

Captain Zhao briefly introduced the development ideas of the whole civilization, including the process of human exploration. In fact, human beings launched probes into outer space very early, such as the famous "Voyager 1" and "Voyager 2". These have very clear written records.

Of course, there is no need to say too much about the core of new civilization historiography.

Whether the other party believes these contents is not within the scope of human consideration. Diplomacy itself is half true and half false. There is no need to tell any big truth, but there is no need to tell complete lies.

After listening to this, the other party was stunned for a long time. He didn't know why. After listening to the whole star journey, he looked very shocked, and even began to whisper a few words in his hometown slang.

A few seconds later, the other party reacted and praised this kind of thinking: "I see. No wonder you built such a huge spaceship and left your home planet... It's an unimaginable huge project! May I ask, how long did it take you to build this huge spaceship? "

"About a hundred years."

If you count the preparation in the early stage, it really took so much time. Of course, this is the earth civilization 3000 years ago. People don't know what's going on with the current earth civilization and whether such a spacecraft can be built.

This group of Gliese were surprised to be speechless again. For them, they may still be in the stage of growth and development in just 100 years

At this time, Zhang Yuan solemnly asked, "Dear Mr. ganyaduo, your civilization launched several nuclear bombs against us at the beginning. Although there were no major casualties, it should also be regarded as an attack. I think you need to explain this attack. "

The famous leader said humbly: "Sir, I want to remind you that this itself is our territory. We don't know your ideology, nor do we know whether you came to this planetary system with goodwill or malice. "

"... would you watch each other grow stronger?"

Zhang Yuan was speechless immediately. If he stood in the other party's position, this statement also made sense.

Then he said, "well, we have sent a lot of electromagnetic waves to the galaxy in advance... Why doesn't your civilization reply? We just regard it as a place without owner. "

"Even if there is any reply, we can't go to this planetary system. There are so many planets in the universe that there is enough choice. "

The other several people were silent, gathered together and whispered for a while, and felt that this question was not easy to answer. Each other has spent 3000 years flying here, and there is no point in defending here.

The Gliese added: "but you can rest assured that general Davian, who pressed the nuclear button without authorization, has swallowed his gun and committed suicide. The majority of the population of our civilization, on the whole, still yearn for peace... If you have no intention of attack and large-scale colonization. "

"But we only allow you to choose one planet as your foothold, and we do not allow you to colonize more planets. This is our bottom line. "

This time, the human side was silent for a while. The other party's concern is not unreasonable. If mankind colonizes all the other planets after hundreds of years, the strength of both sides will change dramatically

But then again, even if you promise to colonize only one, and then go back on it, what can the other party do?

Zhang Yuan didn't want to keep arguing in this regard. He changed the topic: "Mr. ganyaduo, can you introduce your civilization? The 200000 year history of civilization really has a long history. For our human civilization, it is only 10000 years since there are written records. "

This ten thousand year, even three thousand year journey to the stars.

Ganyaduo thought for a moment and said, "this is natural. Exchanging history is also the focus of our contact... We are a civilization that advocates art and Mathematics..."

"... we are even more shocked that you can reach the current level in just 10000 years. This is a rather amazing achievement! "
