Yelu Zhousheng and Watson sat in the flying machine. The terrain below the aircraft will be a gentle slope at one time, and a deep canyon at the other, but the overall terrain is sharply raised, and Watson does not dare to be careless. And Hu Yasheng was talking to himself:

"Who will release the turtle that carried the "Luo Shu"?" Yelu Zhousheng seemed to ask himself, and it was also like asking Brother Watson. He was concentrating on driving and did not speak.

"The river produces a map, Luo produces a book, and the sage is the ...... The Book of Changes says that the turtle emerged from Luoshui with the Book of Luo on its back. What kind of person is ingenious enough to get such a guy who gets up and gets up slowly? The reason for the long distance of the road is secondary, I think it is the person who wants to send the "Luo Shu" - tentatively an alien, he is not sure when this thing will be received by his companions, so ...... He chose a messenger who climbed slowly, but lived the longest. ”

"Of course, the so-called "Luo Shu" is just named by people according to the place where it appears, what do you say, big brother?"

"Aliens are also really interesting, don't pyramids last longer than a turtle?"

"No, big brother, if you have a ready-made Yellow River that you can use to guide the way, will you still bother to build a pyramid? In the land of the Chinese, there are not no places suitable for building pyramids, such as the Eastern Plains and the Northern Plateau, these places must be too far from the target, and a pyramid has been built on the Green Ridge to mark the location. Use a turtle as a messenger and make the shell of the turtle present useful information - the more time passes, the bigger the turtle grows, the more obvious that information becomes. ”

A towering mountain range appeared again below the aircraft, at an altitude of 5,000 meters, and the map showed that this was the Baryan Kala Mountain, which means ancestral mountain in Tibetan. The birthplace of the Yellow River is here. "Land," Yelu Zhousheng said.

The chief said, "We are at the source of the Yellow River." The turtle is an aquatic creature, and if it travels the farthest way to deliver the message, it should be the farthest to make a point of origin. ”

Perhaps the aliens who let it deliver the message have long taken a fancy to the gate formed by the Yellow River, and Luoshui is located in the center of that "gate". If an aircraft flying from outer space to Earth is facing the Asian continent in front of it, the people in the aircraft will be able to see this special gate at a glance.

The great leader of Jerod pondered as he walked. In the Xia Dynasty, it was used for divination called "Lianshan Yi", and he and Watson had just met two mountain ranges: Anima Qing Mountain, the highest attendant in front of the living Buddha; Baryan Kala Mountain - Ancestral Mountain. They are so closely connected that they are even moving in the same direction. He could conclude that there would never be any more such mountains on the entire Tibetan Plateau. Perhaps the name of "Lianshan Yi" is all the information. It's a pity that until the end of the Xia Dynasty, people only used "Lianshan Yi" for divination, and people who understood its true meaning did not appear. ”

It wasn't until the Yin Dynasty that the "Return to Tibet" sent by this alien arrived in the world again...... It's a pity that the people who really understand still haven't appeared. Return to Tibet - Return to Tibet. The symbol of 'Gen' in Yixue is represented by a whole line on the top and two double lines on the bottom, like a bowl that is buckled up - this symbol represents a mountain.

He gestured the symbol of "Gen" in front of his eyes, and the middle of the mountain was empty.

It seems that people like him, who are accustomed to simplifying the complex, are really level-wise. The Grand Leader thought to himself rather conceitedly, and told Watson his induction from the beginning.

He and Watson climbed a high slope.

Watson said, "By the time of the Zhou Dynasty of the Chinese people, the Book of Luo appeared again, but as time went by, the correct meaning it represented became more and more blurred. ”

The leader of Yelu said, "At this time, there was a king of Zhou Wen who was squatting in a deep prison, and he had nothing to do, and he added many self-righteous explanations on the basis of Luoshu. As a result, the important information sent out for the third time has completely become a divination tool! ”

According to the Xia, Shang, and Zhou dynasties, each dynasty had a mysterious message that came out, and was regarded as a classic of easy learning by the world, why was it not after the Zhou Dynasty? Perhaps it was the tireless alien who sent the message for the third time that his life ended. Yelu Zhousheng thought so.

When they visited the pyramids in South America, they had already calculated that after the interstellar accident, there would not be too many aliens on Earth, and it was unlikely that there would be more than three.

Except for the one that built the pyramids in South America and the one buried in northern Africa, there is one person left in the highlands of the Chinese people. So here's the question:

From 2070 BC, when the Xia Dynasty began, to 1046 BC, when the Western Zhou Dynasty began, there was an interval of 981 years. He can't include the era of the end of the Western Zhou Dynasty, because when King Wen of Zhou deduced Zhou Yi, it was before his son King Wu of Zhou conquered Zhou, and at this time, the Book of Luo had already appeared.

Could it be that this alien has lived so long? In 981, "Lianshan", "Guizang", and "Luoshu" appeared three times, and no similar information has been heard since the Zhou Dynasty.

The two of them stopped, and the coordinates of the portable electronic map indicated that under their feet was the starting point of the Yellow River.

The two of them did not expect such a wild and rushing river, and at its source it was also a humble shallow ditch, and a few small springs, and the springs were surrounded by patches of gravel, which really meant that heroes did not ask where they came from. If you don't take a look here, who would have thought that it would be able to turn a thousand times and gallop thousands of miles, and finally achieve an unstoppable momentum!

Yelu Zhousheng said, "All the way we went, there was no water downstream here, and the spring water flowed from the mountain. But here comes the problem, if the turtle really came from here, then it must have been no bigger than the spring here when it first came out. Otherwise, it won't be able to get out. So it must have taken a long time to become big, at least 300 years, right? ”

Watson said, "I don't want to be like you, so I'll simply divide 981 by three, and it's not much worse anyway." ”

"Anyway, I wonder how the alien got in, where is the entrance, and how he managed to live for so long, if the alien is really inside the plateau."

"Anyway, our entrance hasn't been found yet," said Watson, "and neither of us can climb through these springs." ”

Yelu Zhousheng said, "In short, our previous inferences are increasingly showing that there is a great secret in the Qinghai-Tibet Plateau that the aliens want to let their later companions know, which is closely related to the work we are going to do." He waved his hand and said, "Let's go back to the lab and start all over again." ”

He thought about it, and if he couldn't find it, he pulled the engineering team and their excavation equipment all here.
