Kan Xuanxuan shook her head and said, "no, it's not a chimney at all. There should be a downward passage there. The old man seems to be familiar with the environment and terrain here. " Fangqi said, "come on, let's follow the old man."

The three climbed towards the big sand dune. The old man climbed to the top of the sand dune, but sat still, as if waiting for Fangqi them. Fangqi three climbed up the sand dune, which is not small, one-third the size of a football field, like a pyramid built by the Maya. The whirlwind swept away the floating sand above and exposed the large and small stones on the stone city below.

Fang Qi went to the old man and bowed with his fist: "senior, you also like this place." Fang Qi knew that the old man should know about stone city, so he wanted to come forward and talk to others. But the old man with white beard just closed his eyes and ignored him as if he hadn't heard. Fang Qi had to sit cross legged opposite him, motioned them to sit down, and then took out dry food and water to eat.

The old man is like a settled old monk. He has only breath out but no breath in. Fang Qi exaggerated and chewed the beef and steamed bread with his mouth. Even Kan Xuanxuan and Xiao Xiaoling frowned when they saw his eating picture, but they didn't say anything bad because of the old man.

After eating, Fang Qi took out water and took a gulp of it. Finally, he gave two loud hiccups with satisfaction. The old man frowned and slowly opened his eyes. His eyes were cold and disgusted. His voice was hoarse and dry. He said angrily: "ignorant, why do you follow me? Don't you get away!"

Fang Qi stared at him for a few seconds and suddenly sneered: "senior, you won't say this is your family. I guess it's not yours. Since it's not yours, you can't say I followed you. We've been here for a long time. After observing the weather and atmosphere for a long time, I didn't expect you had drilled into the sand. It can't be said that you are close. Just drive others away. "

The old man was speechless by his clever words and sophistry, and directly ran away: "boy, don't play with the man's dragon with me. If I tell you to get away, you have to get away, otherwise, don't blame me for being rude!"

Fang Qi nodded, "Oh, I see. Fight, isn't it?" Kan Xuanxuan and Xiao Xiaoling thought he would have a fight with the old man right away. Unexpectedly, he turned his head and said, "senior, you are wrong to say so. Cooperation is win-win. In such a big stone city, do you dare to say that you can get what you need and retreat unharmed? Not necessarily. We take what we need. We don't want gold, silver or baby. We just want to find a cure formula. "

The old man wanted to do it. After hearing Fang Qi's words, he looked a little thoughtful and said, "well, you find your formula and I'll find what I need." He looked around the three men with two eyes and said disdainfully, "I'm afraid you three young people don't dare do anything to me."

When Fang Qi saw that the old man was finally persuaded, he was relieved and said, "well, senior, we can even form a temporary team. When you are the captain, all three of us listen to you, OK?"

The old man nodded, took out a piece of yellow paper from his pocket and spread it out in front of them: "look at it, too." Fang Qi took it over and saw that it was a hand drawn map, a channel with twisted lines. It was not an ancient city at all, but more like an ancient tomb, which was strange.

The old man untied his baggage, took out a pot cover like Nang, took the leg of lamb wrapped in oil paper in one hand and ate it. Fang Qi sneezed as soon as he smelled the smell of mutton. When he and Miao Miao crossed, they ate mutton every day for a long time. Now they react immediately when they smell the smell of mutton and feel a little disgusting.

The old man gave him a strange stare and turned to eat. Nang is as hard as a stone. The old man's teeth are as simple as chewing a pot. Fang Qi feels a little numb after listening to his bones.

Kan Xuanxuan's slender fingers scratched around on the map and said, "is this still called Dayue city? It's clearly a big moon tomb. " Xiao Xiaoling looked, but shook her head and said, "it's not a tomb. It's an ancient city called urn city."

The old man with white beard who was eating looked back at Xiao Xiaoling and asked strangely, "how do you know?" Xiao Xiaoling raised her short hair in front of her forehead. "There are such urn cities on Shaoshi mountain to deal with bandits and roving bandits." The old man nodded, didn't speak any more, turned his head and continued to eat Nang and mutton.

Fang Qi said, "even if it's an urn, it shouldn't be covered. If the lid is added, what's the difference between it and an ancient tomb. " Leng Buding's old man who was eating interrupted, "this is to protect the urn, fool!"

Fang Qi choked the old man with white beard. He didn't say anything, but he was disgusted in his stomach: don't you know the inner structure of the dead old man? What's the big deal. Unconvinced, let's talk about tongue twisters!

It has to be said that the old man should have been there, and he has come to explore more than once. But this is just the edge of the practice field. If the old man comes to visit the tomb, I'm afraid no one will disturb him. But Fang Qi knows that the whirlwind doesn't blow for no reason. It should have a periodicity. It seems that the old man spent a lot of time looking for what he needed.

The big moon urn is not big, but it is covered with thick sand. It looks like a big sand dune no less than the size of a pyramid. The structure of the urn city should be a large stone house with stone beams. Fang Qi knows that all the cities built in the desert are made of rammed earth and few of them are made of stone. Why is this urn made of stone?

Look at the map. It took many times to draw it. The edge of the yellow paper has been ground into a rough edge. When the passage drawn by pencil is half way, the lower part is blank, but the upper half of the lines are not complex, just a simple horizontal and vertical curved passage.

It's strange. Does this little passage make the old man white beard come again and again? It's unscientific, but if you look at the pencil lines above, it's clear that you've explored it many times.

Fang Qi took out a cigarette and looked at the old man with white beard who had eaten more than half of the Nang cake. He couldn't figure out why the old man came dozens of times. How complicated would it be.

Thinking of the whirlwind formation cycle, Fang Qi turned over the yellow paper and saw that seven vertical lines and a horizontal bar were drawn on the back of the hard yellow paper. Because the paper has color and uses a pencil, I didn't see it clearly when I first took it. Now I finally understand.

The old man with white beard finally ate the Nang cake and wiped his hands on the stone. As if he knew Fang Qi was looking at him, he turned his face. At that moment, Fangqi suddenly had an illusion. It seemed that the old man had seen him somewhere!
