Li Moyun, who returned to Chang'an, was hurriedly summoned to the mouth of the Yellow River by Ling Tan. Li Moyun packed his luggage and ran to Hukou Waterfall. By the time he got there, Ling Tan had been waiting for a while.

The two of them chatted a few words as they walked, "Xiaoyun, I called you here to introduce you to the chief supervisor this time, and by the way, give you a legitimate identity, so that you will not be hindered when you are alone." ”

"Ah, that means I have an official identity?" Li Moyun was a little surprised.

"Well, almost, probably in the capacity of a commissioner, you can apply for help from various regions, as long as it does not harm the interests of the country. Ling Tan explained it roughly, and then led him to the main camp at the Yellow River.

"It can be seen that the quality of the expedition team members who came this time is not bad. Li Moyun looked at the staff who were busy going back and forth and had a sense of identity, at least in this big matter, everyone's intentions were good.

"The exploitation of the country's ancient monuments may upend our perception of the past." The two came to a tent, there were three old people discussing something, Ling Tan answered outside, and only then did the two enter the tent with the consent of the inside.

"It's Ling Tan, it's just in time, we are arguing about the matter of the first bay of the Yellow River for a long time. One of the men with reading glasses said.

Ling Tan nodded, and then introduced to Li Moyun, "These three are from left to right, they are Academician Hao, Academician Zhang, and Academician Li. All three of them are living fossils for the study of historical writing and culture. Li Moyun listened to Ling Tan's introduction, bowed and saluted to show respect, and several old people also nodded their heads one by one.

"This is the one I said, a counselor who has a unique view on the history of the Warring States period. Although he is my nephew, he has completed his PhD and has done several important research, so he is a good person. Ling Tan happily introduced Li Moyun, hoping to leave a good impression in front of several academicians.

"Eh~, whether it has anything to do with it we won't mention it for the time being, as long as we have the ability, we will recognize it, young people tell me your opinion on this ancient Yellow River. Academician Hao, who was sitting on the far left, asked first.

"Okay," Li Moyun thought for a moment and said, "There are ninety-nine bays of the Yellow River in the world, Qiankun Bay forms a big S-shaped turn in the Qin-Jin Grand Canyon, and there are five bends in Yanchuan County, which are called river meanders, also called snake areas. Just at the eighteen bays of the ancient Yellow River, there is an underground palace called 'Taixi Palace'. At the spring equinox every year, a rainbow of water-absorbing landscapes begins to form with the sun. ”

He paused for a moment, "And this tower is shaped like a conch, upside down in the Yellow River Bay, and the interior is vacuum, and it cannot be entered by a human body. Moreover, it is not accurate to say that the Yellow River Bay is not accurate now, it should be called the Yellow River Pan in ancient times, because after the summer when the river water was sufficient, due to the rise of the depth of the water, many large and small whirlpools will be seen at the bend of the Yellow River, and the ancients called the whirlpool as a plate, of which the largest eighteen plates are connected in one place, so there is the name of the eighteen plates of the Yellow River. The current 18 bays are no longer the Yellow River bay of the past, here was once a lake, with the movement of the earth's crust, gradually disappeared, if you want to find the original Qiankun Bay, you must have a previous topographic map. ”

Several people were speechless for a long time after listening to this, and after a while, Academician Hao reacted.

"Yes, young and promising, you are a pillar of the country, continue to work hard, I will pay attention to you. After listening to Li Moyun's explanation, Academician Hao nodded with satisfaction, and the other two also agreed.

Li Moyun left first, leaving Ling Tan and the three of them to discuss the specific location of the so-called 'Taixi Palace' in the Yellow River, as well as what might happen.

In the evening, Li Moyun was reading a book in the camp when he suddenly noticed that Ling Tan had brought a slightly younger woman to his tent. He got up to greet him, and Ling Tan introduced him, "This is your Aunt Li Yan, he is the descendant of Li Daoyuan, we will need to use her strength this time." ”

"Hello Aunt Yan. "Li Moyun is very respectful, and it must not be an ordinary person for Ling Tan to introduce him.

"Hello, I didn't expect that the nephew who Ling Tan praised me all day long would be so young and handsome, and he would definitely be able to be like your uncle in the future, fascinating the little girls in our expedition team. Li Yan opened her mouth and joked about the two of them without any scruples.

Li Moyun is also a personal essence, and when he heard this, he was looking at Li Yan's eyes looking at Ling Tan. Well, the relationship between the two is obviously not as simple as it seems.

Li Moyun thought to himself, "How long has it been since Uncle Tan got out of the shadows?" but the eyes that looked at Ling Tan changed.

Seeing this, Ling Tan had no choice but to cough dryly, shook his head helplessly, and said, "Okay, stop playing, I'm coming over now to have something very important to tell you." Your aunt Liyu has sent us news about what happened in the Imperial Mausoleum Examination. ”

When Li Moyun heard this, his expression immediately became serious. Ling Tan continued, "Last summer, your aunt sent someone to the examination pass in Qinling and found a very important item - the 'Ancient Map of Kyushu'. ”

"Ah, Uncle Tan, are you sure it's the ancient map of the Jiuzhou Continent?" Li Moyun was surprised, because this map was too involved.

"That's right, but based on the message from your aunt, we've determined that ordinary people can't enter, and even those who go in can't get out. Because there is a 'Star Exorcism Coffin' inside, which is the kind of spiritual object that can block the surrounding space, and the map of Jiuzhou is reflected on it, so this time your father must go to it himself, and only he can unlock the 'Star Exorcism Coffin'. ”

"Is it the rectangular stone that said that a coffin is not like a coffin, and that a table is not a table?" Li Moyun suddenly remembered that the strange-looking 'Star Exorcist Coffin' raised his eyebrows, and his face showed an expression of disbelief.

"That's right, in addition, you have to go, that 'Star Exorcist Coffin' is guarded by a stone corpse warrior, and you know your father's state, if you can't get lucky, you can't deal with that corpse warrior, you can only rely on you. Ling Tan's tone was a little serious, and seeing Li Moyun's somewhat solemn expression, he couldn't help but feel sorry for this operation.

"Don't worry, leave it to me, I will definitely bring back the map and leave with the old man. Li Moyun patted his chest and took over the task in a big way, hoping that Ling Tan would be relieved. "Then the 'Red Blood Glass Bottle' depends on you, Uncle Tan, if you have any questions, remember to tell the old man. ”

Ling Tan finally smiled, he finally felt that Li Moyun had grown up, and he was no longer as uneasy as in the past, so he hugged Li Moyun with relief, patted him on the back and said, "Your father and your uncle have already gone, you can go and meet them tomorrow." ”

"Hmm. Li Moyun replied very firmly, looking at Ling Tan and Li Yan who were leaving, sitting on the chair, he didn't know what he thought, and his eyes were a little gloomy.

Early the next morning, Li Moyun said goodbye to Ling Tan and went to Qinling alone to meet his father's uncle. On the other hand, Ling Tan mobilized everyone to find the location of the tower in Qiankun Bay.

Speaking of the road from Li Moyun to Qinling alone, I have to mention that I met a few people from the Zhang family in the middle. Listening to Zhang Yufei, Zhang Zixin's sixth uncle Zhang Yuchang came here before and lost his news, so the main family sent someone here to look for it and wanted to know what happened. She asked Li Moyun what he was doing here, and he dealt with it perfunctorily, but Li Moyun never expected that he would meet Zhang Yufei again in the Qinling Examination.

PS: Li Daoyuan, the word is good and long, a native of Zhuozhou, Fanyang (now Zhuozhou, Hebei), a cool official and geographer in the Northern Wei Dynasty, the son of Li Fan, the assassin of Qingzhou, wrote the geographical work "Notes on the Book of Water", which had a great influence on the development of travelogue prose in later generations, so he is known as the pioneer of Chinese travelogue literature.
