Jiang Yu was stunned: "I remember that the Neanderthals were not ancient Homo sapiens from Europe, why did they come here?"

Professor Jiang, who has always had a weak sense of existence, explained: "It is not surprising that more than 100,000 years ago, the 'Xuchang people' who lived at the Lingjing site in Xuchang City were descendants of ancient humans and Neanderthals in China.

"Although transportation was inconvenient during the ancient Homo sapiens, it did not seem to stop their migration. Many races that now seem to be far away were related to blood in ancient times."

Wu Zheng also explained: "People in modern Eurasian continents have 1% to 4% Neanderthal genes.

"The corpses found in the 'Black Site' are highly consistent with Neanderthal DNA, and they look like direct descendants of Neanderthals."

Jiang Yu looked at the apse that had saved all the bodies elsewhere and seemed very empty. He pinched his chin and said, "I thought they would be descendants of the Xixia Dangxiang people."

After all, the text used in the two is very similar.

Pei Yunqi said: "Dangxiang is a branch of the Qiang tribe. It is said that the Qiang tribe came from the west to the Central Plains. It is probably the ancestors of the Dangxiang people and had in-depth cultural exchanges with the ancestors in the 'Black Relics'."

Wu Zheng pointed to the wall on one side: "Look at this."

Only then did Jiang Yu see that the wall was falling off and faded.

The first picture on the right is a group of people descending from a mountain, and the second picture is a rectangular piece on the heads of the group of people. Some of the rectangular piece looks like something glowing, and there is also a muscular person.

The third picture is a group of people looking for something, the fourth picture seems to be someone dead, and everyone around them looks sad.

These four murals have simple lines, but they are very vivid. Jiang Yu feels that he can basically understand the meaning of the painting.

However, Professor Jiang still explained: "The first painting says that they came down from the foot of the snow-capped mountains. When they set out, they were divided into three groups..."

Jiang Yu was a little surprised: "How do you see it is from Xueshan? They are divided into three groups?"

Professor Jiang pointed to the mural: "Isn't this very obvious? Look at this line as a snow line, and the horizontal bar above is a sign of ice and snow.

"And you see, these people obviously go in three directions, so we infer that this means that they were divided into three groups when they set out, and the people here were one of them."

"I..." Jiang Yu sighed, it was really like a mountain. I didn't expect that people in the archaeology major could find so much information from these details.

But Jiang Yu didn't expect that what was even more terrifying was still behind. Professor Jiang pointed to several points on the top of the mural and said: "Depending on the location of the astrological signs, the place where they set out should be in the middle of the Tianshan Mountains."

Jiang Yu looked at those unspecified points, how could he see this?

Professor Jiang seemed to see Jiang Yu's doubts, so he explained again: "The ancients generally looked at the accuracy of astrological signs without a map.

"Just compare the star map, you can basically guess the general position they want to express."

Then he continued to explain: "The rectangle in the second painting represents the 'black square', and the whole painting means that their purpose is to find the 'black square'.

"The two abstract figures in the 'Black Square', one represents treasures, and the other represents the way people become stronger, or there is a very powerful person in the 'Black Square'.

"The third and fourth murals mean that they have been looking for it for a long time, and have been dead for a generation and have not been found yet.

"The author of this painting should be an ancient man. We guess it is probably the second generation who settled here. They are afraid that their descendants will forget their purpose, so they painted these four paintings to remind future generations at all times.

"The person who died in the front hall may be the last person in this tribe.

"Otherwise, if it was a migration, it would be a bit unreasonable.

"After all, herders had seen them nearby more than 20 years ago. If a tribe of dozens of people migrated, it would definitely not be concealed by the local government, but we have not found any relevant records in the local area."

Maybe the other party was still looking for the "black side" until there was only one person left, but unfortunately the "black side" had already been buried under the yellow sand.

Jiang Yu said: "That legacy document is more important than imagined. Maybe there is a way to open the 'black square' in it."

Then he asked: "Can you see from these murals why they were looking for the 'black side'?"

Professor Jiang shook his head: "There is no relevant description, but we guess that since they clearly know the existence of the "Black Party", they should have seen the "Black Party" or heard relevant legends.

"The former is more likely. We have consulted relevant scholars in the local area. There is no legend about the 'black side' in Xinjiang area.

"Maybe someone in this clan has contacted the Black Party and has gained great benefits, so it can motivate the entire clan to find the Black Party."

Jiang Yu nodded slowly. Professor Jiang's guess was very reasonable. He continued, "How do you plan to use these clues next?"

Wu Zhenghui reported: "We are going to divide into two groups, one group will continue to decipher the 'Black Square Bus Volume', and one group will try to find their origin, and perhaps find more clues from there."

Jiang Yu nodded, expressing his agreement with their ideas.

Wu Zheng also took Jiang Yu to visit the water source of this tribe, and there was a downward passage in the other direction of the front hall.

That passage is longer and leads directly to an underground river.

The fish eaten by this group were actually caught from the underground river.

The underground river should have a part of the ground in unknown places, otherwise there would be no fish.

That night, Jiang Yu lived in the camp. The temperature here dropped rapidly after the sun set. Although it was early summer, the temperature at night was still in single digits.

Jiang Yu stood outside the tent, watching the wind blowing the tent "hula hula" and listening to the sound of the wind wiping across the wind-eroding rocks in the distance, he always had the illusion that he was in a different world.

"Team Leader Jiang, are you looking for me?" Pei Yunqi, who was wearing black-framed glasses.

Jiang Yu smiled and said, "Yes, come in and talk."

He poured Pei Yunqi a glass of water: "In the afternoon, I heard Wu Zheng say that Professor Pei not only studied ancient Chinese, but also studied cuneiform and hieroglyphics?"

Pei Yunqi held up his glasses: "I dare not take the research, I understand it briefly, but I understand it briefly."

Jiang Yu smiled and said, "You are too modest. I want to ask Professor Pei to tell me about the relevant knowledge about writing."

When he saw the 'Black Square Bus', he suddenly realized that there was a huge loophole in his next plan, so he asked an expert to talk to him.

Pei Yunqi drank a sip of water: "There are actually two types of words, one is pictographic and the other is letters.

"The formation of words is closely related to people's living environment.

"For example, there is a kind of papyrus in the Nile River Basin, and just by spreading it out, it is a natural writing material. Therefore, Egypt's hieroglyphs are very detailed, and each character is basically drawing a painting.
