When Chu Nanxing came back with Kong Xilan, he saw Tu Guiyong sitting in the room with his head bowed, and he couldn't hold back his joy.

"Brother, what's wrong with you, you were cooked?"

Tu Guiyong replied weakly, "When you left yesterday, you didn't give me anything to eat, I was hungry in the observation area for a night." In addition, when I entered the base, I was chased by aliens, and in order to run fast, I lost all my luggage, and until now, I haven't eaten for a day and a night. ”

Several people saw that Chu Nanxing did know this person, so Mother Confucius hurriedly went to the kitchen to bring food.

Tu Guiyong devoured it, and at this time Mother Confucius spoke next to him, "Xiao Chu, how is it that you went to check the water source, there is not much water in the team." ”

Chu Nanxing remembered the stream in the space, so he said, "I'll solve the problem of domestic water, you don't have to worry." ”

When Confucius heard this, she relieved her heart and stopped talking.

At this time, Qin Shuyin walked over with a notebook, "Since everyone is okay today, I'll tell you about the recent new discoveries." ”

Qin Shuyin patted Chu Nanxing's shoulder, "Yesterday Ah Chu told me something, I think you must have also discovered that most of the power sub-people you have seen in the base are men with low height and strong torsos. ”

Qin Shuyin looked at the bald head and added, "It's rare to see a bald head as tall. ”

Qin Shuyin flipped through his notes, "This is somewhat consistent with a document I once saw. ”

"Do you know what kind of primitive humans the earthlings evolved from?"

The bald head said without thinking, "As far as primitive people are concerned, how many other primitive people can there be?" ”

Qin Shuyin shook his head, "You don't know, we are all descendants of Homo sapiens. But in the history of evolution, hominids had other races. ”

Xu Yangui asked, "Just like the yellow race, the black race and the white race?" ”

Qin Shuyin smiled, "It's not like this, in fact, people usually distinguish races by skin color, which is not recognized biologically. ”

"I'm talking about a subspecies of humans, and I think the base must have discovered something as well, otherwise we wouldn't be called subhumans."

The bald head is not patient enough, "You said for a long time, why are the power subhumans so short, you didn't say it." ”

Qin Shuyin gave him a slightly calm look, "This is going to start with an extinct race, on the way of Homo sapiens out of Africa, I have met many other human races. ”

"Among them, there is a race of people who are on a par with Homo sapiens in intelligence and physical strength, and sometimes even superior, and that is Neanderthals."

"But this race is extinct, and as for why they became extinct, it is still an unsolved mystery, so I won't say more."

"However, it is worth mentioning that Homo sapiens had a genetic blend with Neanderthals. In addition to the native African blacks, a large proportion of whites and yellows carry Neanderthal genes. ”

"This species has very distinctive characteristics, compared to Homo sapiens, they are short and strong, with large bones, a high nose bridge, and can adapt to the cold environment."

"This kind of external characteristics are not obvious in Asians, but they are often reflected in Europe and the United States, such as a high nose bridge, large skeleton, and blond or reddish-brown hair, which are all Neanderthal characteristics."

The bald head slapped his thigh, "So, we're all mixed-race!" ”

Chu Nanxing touched his chin, "I have a question, if you follow what you said, the survival rate of Asians and Europeans and Americans should be basically the same." But in reality it doesn't seem to be the case. According to the base's broadcasts, Asia, despite its high population density, seems to have survived a higher rate than Europeans and Americans. ”

Qin Shuyin flipped the notes back, "You're right, this is about to mention another race, the Denisovans. Of the three people of color, only the yellow race carried the genes of the three primitive races. ”

"Although there is no evidence that these genes have an effect on the virus. But as you can see, in African countries, they have less than three percent of their population, which is almost annihilation. ”

Qin Shuyin lowered his eyes, "Homo sapiens has survived in evolution for so many years, it is impossible for them to be the dominant species forever. Perhaps in the near future, Homo sapiens will become extinct and replaced by genes that are more adapted to the environment. ”

Chu Nanxing patted Qin Shuyin's shoulder comfortingly, "Don't talk about this, a higher survival rate is a good thing for us." ”

"Let's rest for a day today, and if you have armor tomorrow, you will also follow me on a mission, no comment."

Everyone said in unison, "No opinion." ”

Chu Nanxing coughed twice, how did he feel like a leader inspecting, weird.

"Tomorrow we will try to find a water plant that produces bottled water, it will take some time for the base to clean up the water source, and we will prepare the water for the team ourselves."

Chu Nanxing turned his head to look at Qin Shuyin, "As for Shuyin, you will also go out with us tomorrow, with a medical kit, now that the xenomorphs have evolved, it will be more dangerous to go out." ”

After Chu Nanxing finished speaking, she saw Kong Chengsi with a longing face, she rubbed Kong Chengsi's head, "Our little leopard and orange will stay at the base tomorrow to protect the other team members." ”

Kong Chengji lowered his head in disappointment, eager to grow up quickly.

At this time, the cry of the fortress came from the courtyard, and it was clear that someone had come in.

When Chu Nanxing and the others went out of the room, they saw several people wearing the uniforms of the personal guards walking in, they were the guards of the base chief.

One of the men, Chu Nanxing, had seen it, and it was the one who stood next to the base chief yesterday.

He walked straight over and smiled kindly, Chu Nanxing instinctively felt that he must have something to ask for, otherwise why would these regular soldiers come to him if they had nothing to do?

The man cleared his throat, "Captain Chu, I came this time to meet the orders of the base chief." ”

"What does the base commander command, if it is within our ability, we can naturally receive the order."

"That's right, on the battlefield yesterday, one of your pets ......," the man said, looking at the fortress.

The fortress felt the chrysanthemum tighten, and was so frightened that he hurriedly ran to the corner to install the background board.

The man smiled awkwardly, "It's this rooster that seems to boost morale." ”

Chu Nanxing raised his eyebrows, "Hmm, so what does the base chief want the fortress to do?" ”

"We've been going out a lot lately to clean up xenomorphs, so we're thinking of borrowing the fort for use."

Chu Nanxing refused without thinking about it, "I'm very sorry, I can't agree." ”

One of the guards in the back was very dissatisfied, "Why are you so irresponsible, and the base cleans up the xenomorphs for everyone." ”

"Xiao Chen!"

The man sternly stopped the guard just now, "I'm sorry, he is young and short-tempered, Captain Chu should not be like him." It's just that I want to know what your reason for refusing is, and I'll go back and figure out a way with the base commander. ”

"These evolved animals are not just pets for me, they are also my family, and I am not comfortable lending them to others because of the lack of ability to protect myself. But ......"

"But what?" The man looked at Chu Nanxing eagerly.

"If you clean up the xenomorphs and bring our team, I can consider taking the fortress on a mission."
