Two days before departure, Tang Feng received a call from Meng Gongyun.

"Mr. Tang, I have come back from Jinyang. I have sorted out my research achievements on Kunlun Mountain in recent years and brought all the valuable ones. If it is convenient for you, will you allow me to visit?"

Listening to Meng Gongyun's voice, he was excited and couldn't wait.

Tang Feng can imagine how Meng Gongyun has been enjoying himself during this period of time when his body has recovered and his physique is even better than that of more than ten years ago.

"Come here now." Tang Feng light should be a sentence.

After hanging up the phone, Tang Feng gave Rong Guocheng another call and said, "two hours later, you come to my house. I'll let you meet the people who are going to Kunlun this time. You can make an arrangement."

"Yes, Mr. Tang." Rong Guocheng responded immediately.

This time he went to Kunlun, there were a lot of people, and it was quite complicated. Tang Feng planned to leave all the logistics work to Rong Guocheng, so that he would have a free time.

According to Rong Guocheng's ability, such a small matter is nothing at all.

Tang Feng strolled into the garden and saw Ji Ning talking with Shangguan.

In the early morning, Zixuan volunteered to follow Lin Mengjia when she went shopping. Shangguan usually didn't like shopping very much. With Zixuan's enthusiasm, she was so happy that she stayed in the villa and didn't leave.

Ji Ning and Shangguan are talking, and they are still comparing. Obviously, they are exchanging ideas.

These two people, who were originally quite cold tempered, are now able to say a few words when they come across one place, which is extremely rare.

When they saw Tang Feng, they stood still and saluted him.

Tang Feng said to Ji Ning, "go and pick up your sister-in-law. I have something to look for her."

"Yes, sir." Ji Ning answered and left.

sister-in-law? Shangguan looks at Tang Feng with some suspicion. She doesn't know what happened to Tang Feng in Ji's old house. The last time changsunying came to the villa, Shangguan wasn't there, so she didn't know about changsunying.

However, even if it was strange in her heart, she was cold by nature. It had nothing to do with her. She didn't ask much about it. Seeing that she didn't have something of her own, she nodded to Tang Feng and turned to leave.

Soon, Meng Gongyun arrived with Meng Zhong.

When he saw Tang Feng, Meng Gongyun's eyes and eyebrows were all smiling. He was quite different from Tang Feng when he first came here.

Meng Zhong carries a small suitcase in his hand and follows Meng Gongyun.

"Mr. Tang, these are my materials."

After sitting down on the sofa, Meng Gongyun motioned to Meng Zhong. Meng Zhong immediately stepped forward, opened the small suitcase and showed Tang Feng everything inside.

Among them, there are piles of thick papers and books, as well as some photos. Tang Feng is not very interested in those manuscripts. What attracts his eyes is a huge map.

The map was folded several times and put in the trunk. When it was opened, it was two square meters.

Meng Zhong unfolded the map and spread it on the tea table.

Seeing that Tang Feng was interested in the map, Meng Gongyun said: "this is the route map of Kunlun that I recovered from the memory of the map I saw on the bronze plate and the route we actually took. The route of the original map is drawn from my memory. Maybe there will be some differences in some places."

Tang Feng gave a "hum".

At the beginning, the map Meng Gongyun saw was carved on a bronze plate. According to Tang Feng's conjecture, the map should have come from the changsun family. Now, instead of imitating the original bronze map, Meng Gongyun provides it, which is hand drawn and printed with copperplate paper. It looks very clear, which is no different from the map sold on the market.

Tang Feng wants Chang Sunying to come over, which means that he wants her to verify his conjecture.

Seeing Tang Feng carefully looking at the route above, Meng Gongyun quickly explained: "the red line on the map is the route on the bronze map that the man took, and the green line is the route we actually took after we actually arrived at Kunlun."

Tang Feng nodded and looked at the two color lines above. At first, the two lines converged. Later, they gradually diverged. Later, they converged again. In this case, there were several places.

"After we arrived at Kunlun Mountain, we wanted to follow the route on the map, but some roads were unable to move forward, or there were cliffs, or were blocked by lakes, so we couldn't move forward at all, so we had to make a detour."

As he spoke, Meng Gongyun took out a thick book from his suitcase, opened a page of the colorful illustrations, pointed it out to Tang Feng, and said, "I have studied the changes on the Kunlun Mountains for thousands of years. It's very normal for the terrain to change because of the crustal activity. Even if this is the route we've been to before, maybe if we go again this time, There will be changes, too. "

Tang Feng glanced at the color map. It was a sketch map of some crustal changes. He only nodded and said, "your map has been very detailed. If there is any further change, we will wait until we get to the place to think about countermeasures. Later, I have a friend who has met with this map. Maybe she can put forward some suggestions."

After all, the people in the changsun family know much more about Kunlun than others. Changsun Ying is very interested in Kunlun. She will find something when she sees the map.

Meng Qiongyun looked a little surprised and said, "has anyone else seen this map? This man is -- "

"Here she is." Tang Feng lightly interrupts Meng Gongyun's words and slightly raises his chin toward the outside.

Meng Gongyun looked over and saw that the door of the villa was open. A man and a woman were coming here.

In a moment, Sun Ying and Ji Ning have arrived in the living room.

Ji Ning respectfully said to Tang Feng: "Sir, my sister-in-law has received it. I'll leave first." Then he nodded to Chang Sun Ying and left by himself.

Chang Sun Ying enters the door and sees two strangers in the living room. Both of them are ordinary people. They are a little surprised. They look at Tang Feng with inquiring eyes.

Meng Gongyun and Meng Zhong were also surprised to see Chang Sun Ying. Obviously, they did not expect that Tang Feng's friend would be a young woman.

Tang Feng pointed to the huge map on the tea table and said to Chang Sun Ying, "this map is provided by Professor Meng. You may as well have a look. Is it familiar to you?"

Chang Sun Ying is still puzzled. Although she doesn't know what Tang Feng's intention is, she glances at the map and her pupils dilate instantly.
