In the Zhugou cave, Wang Ke and Hai Ling came to Dr. Yuan's room.

The situation inside is lively today, almost everyone is here, and Enron!

"Koko!"

When An Ran saw Wang Ke and Hai Ling, he immediately shouted, walked up quickly, and stretched out his hand to hold Wang Ke's hand: "You two are so good, I thought our earth was finished, and even Dr. Yuan had no choice!" ”

"It's all sea spirit smart!"

Wang Ke smiled and said, "After you came back, you also made meritorious contributions, and you have been with Dr. Jiqiong all the time?" ”

"Well, we've been together, watching over the little grayman's base!"

An Ran said happily: "Xiaoke, I have learned to drive the Blue Star Flying Machine!" ”

"Okay!"

Wang Ke smiled and said, "I'll just say that you are very smart!" ”

The two were chatting, and everyone was laughing.

Wang Ke was slightly surprised.

From that safe return home to being picked up later, there have been many things in between, including his return to the Blue Star and a series of attacks by the little gray man.

Although it was a complete victory and defeated the little gray man, it also almost experienced a mass extinction of the human race.

In Wang Ke's opinion, An Ran will definitely pounce on him excitedly and hug herself tightly, although it is not what she wants, and she doesn't want to see it, but she is very likely to do it.

But in fact, Enron didn't, he was very happy and held his hand.

"Xiaoke, you and Hai Ling are really outstanding!"

Dr. Yuan also smiled and said: "The result this time is something I didn't expect, at that time, I almost thought of leaving, according to the words of the earth, it is called to stay in the green mountains, not afraid of no firewood!" ”

Wang Ke was amused and laughed: "Dr. Yuan, it's not my credit, it's all Hai Ling's cleverness, she came up with the idea!" ”

"Yes, Hai Ling is indeed smart, and he is also my most proud disciple!"

Dr. Yuan looked at Hai Ling, smiled with relief, and then pointed outside and said, "Xiaoke, let's go over and take a look, the situation of the little gray people is very unexpected by me, their corpses, are they going to be sent back?" ”

"There is no urgency, the person in charge and the heads of various countries have not said it."

Wang Ke was taken aback, and asked as he followed Dr. Yuan out, "Are those two little gray men dead?" What was unexpected? ”

Dr. Yuan didn't rush to answer, and took Wang Ke and the others to a room, which was the room of the middle-aged man who sold vegetables last time.

At this time, there were two little gray men lying on the bed, one of them seemed to have been examined by Dr. Yuan, they were wrapped in a thick layer of things, and some liquid could be seen around them, but it was not red, but black and gray.

Is this blood?

The blood of the little grays, not red?

"They're not carbon-based lifeforms, they're silicon-based lifeforms!"

Dr. Yuan then said: "This situation is really beyond my expectations, and it also breaks our understanding of living beings, although we have guessed in the past, but we have never seen it with our own eyes. ”

Wang Ke was taken aback!

When I first discussed with Dr. Yuan, I thought that earthlings were very lucky, even with gods or an environment designed by the Creator, so that earthlings could have a relatively ideal living space in the extremely harsh environment of the universe.

Dr. Ke Yuan said that things may not be what he thinks, and perhaps, it is precisely because of the earth's environment that human beings who adapt to the earth's environment are born.

Dr. Yuan believed that there might be various forms of life such as silicon-based, amino-based, and sulfur-based life, and sure enough, they appeared!

At this time, Dr. Yuan also explained to everyone.

According to Dr. Yuan's research and the research results of scientists on Earth, it is almost the same that the molecular structure of silicon-based life forms is not stable enough.

Even if there are living organisms, it is difficult to survive, and if there are Homo sapiens, then their lives are destined to be very short, and they will not derive a high civilization.

However, the reality is that silicon-based life forms do exist, and they have also derived a high degree of civilization.

The little gray man is an example, although the bones are small, but the structure is complete and strong, and the skin on their body, perhaps after many years of evolution, is completely different from the skin of earthlings, it is a very thick layer of skin, which has a very strong protective effect on internal organs, and is suitable for survival in high temperatures.

This may also be the reason why the living environment of Gliese 581d is extremely harsh, and a high degree of civilization can be derived, they are the sapiens who adapt to that environment and breed.

What Wang Ke saw was that there was a pitch black on a person's leg, because in the process of falling, his internal organs were shattered, but the blood could not be discharged, forming a blackened color under the skin.

"There are many other mysteries, I haven't had time to study them for a while, since your general leader didn't say to bring them back, stay here for the time being, I will get more information about extraterrestrial civilizations."

Dr. Yuan smiled and said, then looked at Wang Ke and said, "Xiao Ke, at present, the attack of the little gray man has resisted, and it can also be said that the earth humans have eliminated the little gray man, but the matter is far from over, have you thought about it?" ”

"I've thought about it!"

Wang Ke immediately nodded: "Moreover, I am also worried that they will attack immediately!" ”

"Oh?"

Dr. Yuan frowned slightly and asked, "What do you think?" ”

"The reason is also very simple, there are roughly three points!"

Wang Ke didn't dare to fully explain to the person in charge just now, in case what he said was wrong, there was nothing he couldn't say to Dr. Yuan and the others: "The first point is that the purpose of their coming to the earth is very clear, to enslave human beings, colonize the earth, and rule the earth, this original intention will not change!" ”

Dr. Yuan and the others all nodded, this is for sure, otherwise they would not have come to Earth, and they had a short cooperation with the mold country!

"The second point is the destruction of the environment by the earthlings!"

Wang Ke then said his thoughts: "Since the little gray man is very worried, then, the man in black must also be very worried, the earth has been attacked by the little gray man, they must know the specific situation, now that they do it, we earthlings still have no room to fight back, I'm not sure, is it possible?" ”

"Totally possible!"

Dr. Yuan immediately nodded: "Their level of technology may be able to avoid our detection, it is impossible for them not to know about such a big thing happening on the earth!" ”

"If you want to talk about the third point, it's Riggs!"

Wang Ke said very worriedly: "Riggs was discovered by us unintentionally, through the attack of the living memory fiber group, if it weren't for you to explain that he is not an earthling, we still don't know, then, will there be some huge conspiracy hidden here?" ”

"Yes!"

Dr. Yuan nodded seriously and said, "I've always had a lot of doubts about Riggs, and it seems that you need to see him again." ”
