Wang Lihong and Lan Xi are very serious, and they have been pondering everywhere, not wanting to let go of any possibility.

"This fucking disgusting, how many broken doors, walking corpses, crows, and what kind of bird-man head Gu, I've been in here for so long, and I haven't seen a few valuable things, why do you embarrass me this first emperor, and now there is a broken iron door blocking here." Wang Lihong complained unhappily.

"Iron Gate? Iron gates? Wang Lihong repeated it several times, as if she remembered something.

He immediately ran to Wang Zhichu's side and said to him: "Professor Wang, you know more about this terrain, look at the mountains and rivers of Kyushu, and see that there is nothing unusual. ”

"Lihong! What do you mean by that? Wang Zhichu asked puzzled.

Wang Lihong scratched his face, and then said: "That's the case, these mountains and rivers in Kyushu are all made of metal, and I was wondering if this clue would be hidden in these mountains and rivers maps." But I'm not very good at geography, so I'll let you see. ”

"What? You say that all these mountains and rivers are made of metal? Wang Zhichu's expression immediately became serious and nervous.

Wang Lihong responded: "Yes! I also found out when I fought Xiaohuo before. ”

Wang Zhichu didn't say a word, and immediately headed towards the highest peak.

Wang Lihong and Lan Xi also followed.

When they walked to the highest and highest mountain range, Wang Zhichu began to carefully observe the terrain of these mountains and rivers around him, and Lan Xi was also helping with his heart.

Although Wang Lihong said that he was also very serious, he looked at it, it was like looking at the scenery, and he really couldn't see why he came, so he could only wait to see if Wang Zhichu and their side found anything and did the errands by themselves.

Ten minutes!

Half-hour!

Fifty minutes!

One hour!

An hour passed so quickly, and the whoosh passed unconsciously.

Wang Lihong was about to fall asleep when he stayed here, but Wang Zhichu and they didn't have a result yet.

Wang Zhichu and Lan Xi observed carefully. While discussing and discussing, Lan Xi drew and recorded in his notebook with a pen.

Wang Lihong was bored, dozing off, and his head was like a chicken pecking rice, hanging a little.

"Found it! So that's what happened, hahaha......"

At this time, Wang Zhichu suddenly burst out laughing, and directly woke up Wang Lihong, who was dozing.

Wang Lihong stood up and patted her buttocks. He approached Wang Zhichu and Lan Xi and asked, "Professor Wang, what's wrong, have you found any clues?" ”

Wang Zhichu said to Lan Xi: "Xiaoxi, you can show it to Lihong." ”

Lan Xi flipped the notebook in his hand to the front several pages, then handed it to Wang Lihong and said, "Lihong, the clue is on this terrain." ”

Wang Lihong took it, looked at it, and said embarrassedly: "I'm sorry." I really don't understand, so I'd like to explain it. ”

Lan Xi turned the notebook to the first page, and there were many lines drawn on it, which Wang Lihong couldn't understand at all.

Lan Xi saw him at a loss. Then he began to explain: "Lihong! In fact, we were misled by the terrain from the beginning. ”

"Misleading?" Wang Lihong asked curiously.

Lan Xi nodded, and then said, "Yes." Look here, this mountain is Mount Tai. Look at this mountain again, and this mountain is Song Mountain. ”

Wang Lihong was still at a loss. Say, "Is there anything wrong with that?" ”

Lan Xi pursed her lips and smiled, and said, "Lihong, do you know that these two mountains are in that place?" ”

Wang Lihong nodded and said, "I know this." This Mount Tai is in the middle of Shandong, this Songshan is in the middle of Hunan, and then what? ”

Lan Xi pointed to the map of Kyushu in front of him and said to Wang Lihongshu: "Then take a look at it, what is the difference between these two mountains?" ”

Wang Lihong reacted at this time, and suddenly realized: "Yes, I'll rub it, these two mountains are actually next to each other, which is indeed wrong." ”

"Yes, you've finally found out." Lan Xi was relieved to see that Wang Lihong understood.

However, Wang Lihong still had a question in his heart, he said: "But how can you be sure that these two mountains are Mount Tai and Song Mountain?" If this is not the case, then wouldn't it be a mistake, after all, there are so many mountains in this world, and it is impossible that there is no other mountain next to this Mount Tai. ”

Wang Zhichu spoke at this time, and he said: "Lihong, what you said is right, so we carefully confirmed it. First of all, since the Qin Dynasty, the earth's crust has not changed much, and the topography, mountains, rivers, and rivers at that time are basically the same as those now, and with this as a basis, we can draw some conclusions. ”

"What's the conclusion?" Wang Lihong asked.

Wang Zhichu pointed to those water and Yinhe Dao and said: "That water Yinhe road represents the Yellow River, and that one, that is the Yangtze River. Let's take the location of the Yangtze River and the Yellow River as a reference, and then we can make it clear. If you look carefully, the location of Mount Tai is correct, but if you look at the location of this Songshan Mountain, what is it? ”

"It's an open space." Wang Lihong replied.

"Yes. It's an open space. That's because the location of this Songshan Mountain is reversed from this open space. If you look at the water galaxy on the left and right sides of this Songshan Mountain, do you see anything different? After Wang Zhichu explained, he asked again.

Wang Lihong observed it carefully, and sure enough, he saw that there was a situation, and said: "The rivers on the left and right sides are the same, but they have become a mirror effect, that is to say, if this Songshan Mountain is moved to the position where it should be, these two rivers will still be perfectly connected." Oh, I see. ”

Speaking of this, Wang Lihong finally fully understood, it turned out that this Kyushu mountain and river map had been passive with very subtle and wonderful hands and feet. Many places have been modified by moving. Not to mention, if you are not familiar with geography and do not know how to use the Yangtze River and the Yellow River as reference coordinates, it is really difficult to discover the secrets between them.

"Damn, this person who designed this place is really awesome." Wang Lihong couldn't help but praise. Whether it is the beak of the phoenix or the secret door of the passage of the walking corpse, it is really very clever, and the wisdom of this ancient person is really a bull.

Lan Xi explained again, pointing out the other three different points one by one.

"Professor Wang! Lan Xi! You two are so powerful, I didn't expect you to find out. Hey, erudition is good. Wang Lihong also admired Wang Zhichu and Lan Xi very much.

Lan Xi was praised and was very happy, smiled, and said, "Of course, otherwise what are you looking for us to follow, it's not to join in the fun." ”

"That's too." Wang Lihongtian shamelessly shy for a moment.

This clue has been found, but how can this be reset? This is also a big problem. (To be continued.) )
