No matter what Mu Chonglan did, things couldn't change anything, so they still quietly left Longtong County according to the previous time.

"Longtong County, this name, before I came, someone named Longtong, but it turned out that it wasn't." Mu Chonglan leaned on the window of the carriage and said casually.

Xiao Xiantang glanced at Mu Chonglan and said, "The reason why Longtong County is called Longtong County is because there are a large number of copper ore veins underground. ”

Hearing Xiao Xiantang's words, Mu Chonglan's eyes widened and said, "How come I have never heard of it?" ”

"This was before we came here, you don't know, you haven't heard of it, there's nothing strange about it." Xiao Xiantang explained lightly.

Mu Chonglan frowned when he heard this.

Seeing this, Xiao Xiantang knew that Mu Chonglan was starting to compete with himself again, so he said, "Do you have any of the underground towns in Longtong County?" ”

"You mean, where the fake pirates used to smuggle?" Mu Chonglan looked at Xiao Xiantang puzzled, not knowing why Xiao Xiantang suddenly talked about this matter.

After all, when he first appeared in this underground town, Mu Chonglan was also very excited, and he had to run down to see and play almost every day before he came back, but as time went by, Mu Chonglan had completely lost interest in the underground town and never went to it again.

Therefore, at this time, when he heard Xiao Xiantang mention the town on the ground, he would react like this.

Xiao Xiantang said: "Do you think that those underground passages are specially dug out by those fake pirates in order to transport smuggled goods?" ”

"Isn't it?" Mu Chonglan asked, but he also vaguely understood in his heart that he must have guessed wrong, otherwise Xiao Xiantang would not have reacted like this.

Xiao Xiantang nodded and said, "Yes, you guessed wrong." ”

"Did I guess wrong?" Mu Chonglan thought for a moment and asked, "What is the truth?" ”

"The truth, it's those passages, in fact, they are not specially dug out, but to dig the copper mines below Longtong County, understand?" Xiao Xiantang said calmly.

After listening to Xiao Xiantang's calm words, Mu Chonglan thought for a moment, then nodded and said, "I see, I didn't expect there to be so many meanings in this name." ”

"Choosing a name for a county seat is mostly easy to remember and representative, so it's not surprising that you can see so many names that look strange but are closely related to their own county." Xiao Xiantang explained that others may know about this kind of thing, but Mu Chonglan may not know, so he has to tell Mu Chonglan specifically.

Mu Chonglan nodded her head, as if she understood, but in fact, whether she understood or not, it was up to her to ask.

However, Xiao Xiantang didn't mean to dwell on this matter, after all, compared to dwelling on this matter, he felt that it was better to think about the things after that, after all, this is a matter of life and death, and Mu Chonglan's curiosity is not so life-and-death.

Confused by Mu Chonglan, Xiao Xiantang took out the map and circled all the places he expected in his heart.

Mu Chonglan on the side was still yawning boredly, but when she saw Xiao Xiantang take out the map, she came over curiously, looking at the detailed map, she began to speak: "Such a complicated terrain." ”

"It's a little complicated, but since it's a treasure cave, it's not surprising that it's hidden." Xiao Xiantang replied.

Mu Chonglan nodded, then glanced at the map again, then pointed to one place and said, "This place." ”

"What's wrong with this place?" Xiao Xiantang asked puzzled.

Mu Chonglan grinned, showing a mouthful of white teeth, and said, "This may also be the entrance, you didn't circle it too." ”

"Here, it should be a mountain stream spring." Xiao Xiantang said.

Mu Chonglan nodded: "Well, but the waterway can also become the entrance, when we were in the tower tomb before, didn't we enter it through the waterway?" ”

Xiao Xiantang looked at Mu Chonglan, he knew before that Mu Chonglan could understand the map of the naval battle, but he didn't take it too seriously at that time, after all, Mu Chonglan ran around on the sea every day, and he was familiar with the terrain, and there was nothing strange about it, not to mention, there were not too many hiding places in the naval battle, so the map of the naval battle had no special significance, so when he knew that Mu Chonglan would look at the map of the naval battle, he didn't take it seriously.

Now, seeing that Mu Chonglan could actually understand these very complex maps, he began to mumble, always feeling that things were a little strange, after all, what Mu Chonglan could understand was always simple, and this map was not simple.

Perhaps, Mu Chonglan is as talented as she is in business when it comes to looking at maps.

Xiao Xiantang thought in his heart that he had taken out a few maps and asked Mu Chonglan to distinguish them and find out where he asked her to find them.

Mu Chonglan did not disappoint Xiao Xiantang, basically she was able to find the place that Xiao Xiantang asked her to find very quickly, and there was no mistake, and even, in order to confuse Mu Chonglan, Xiao Xiantang deliberately found a few maps that even he had to be confused and could only be determined after careful identification, so that Mu Chonglan could distinguish, and Mu Chonglan did understand the map very well, and it was very simple to find out all the places that Xiao Xiantang asked her to find, and she was not confused by the map at all.

This made Xiao Xiantang surprised and delighted, what surprised him was that Mu Chonglan was actually a genius who knew the map, and he didn't know, as for the joy, it was that Mu Chonglan had such a talent, how could it be good, and he could also help himself a lot.

However, whether it is surprise or joy, Xiao Xiantang feels that this is a good thing.

"You have the ability to read maps, we should get twice the result with half the effort when we go to find the treasure in "Tongtianlu" this time." Xiao Xiantang said.

There are a lot of entrances they have found now, but they are basically wrong, if Mu Chonglan has this ability to find the map, then it should be of great help to them to distinguish which is the real entrance.

Thinking of this, Xiao Xiantang felt very happy, so he reached out and touched Mu Chonglan's head twice more as a compliment. "I'm getting smarter."

"Hey, hey." Mu Chonglan is a person who likes to be praised very much, especially the person who praises herself is Xiao Xiantang, so she is even happier, because Xiao Xiantang is too strict, she can not be scolded by Xiao Xiantang for being stupid, it is already time to burn incense and worship the Buddha, let alone be praised by him.

Therefore, when Mu Chonglan was touched on the head, what he thought in his heart was that he would be so happy that he couldn't sleep at night when he was praised like this.
