"The energy pressure is gone..."Su Fei carefully sensed that the fluctuation of the energy pressure collision had disappeared, and couldn't help frowning.

What happened just now should be a pursuit battle, and those few Neng Xiu were also fighting and moving, and the three of them pursued the fluctuation of energy pressure for nearly half an hour, and finally stopped in front of a palace on the edge of the cave.

Meng Tian stepped forward and wiped the loose soil on the roots of the palace building with his hand, put it in front of his nose and sniffed it, there was a fresh and damp smell...

"This palace seems to have come up newly, maybe this is the underground palace that was opened this time..."Meng Tian was still speculating whether someone had deliberately led them here, but now he was a little relieved.

"Is this the place?" Xiao De looked up at the palace when he heard this, this palace was one of the few that was not tilted, but almost half of it was embedded in the cave wall, which looked a little different.

"Let's go in and have a look. Meng Tian was also unsure, but he still cautiously instructed Su Fei and the two to prepare for battle.

"Where should we get in from?" Xiao De unconsciously recognized the status of Mengtian's decision-maker, and asked him how to choose at this time.

The palace doesn't seem to have fully emerged from the ground, so there are no gates or anything like that, so the entrance to it is the windows. Although the palace is usually set into the stone walls of the cave, it is still very large, and there are too many windows to count. Most of these windows are full of bright light, and it is obvious that there is also a light source inside the palace, so the people of Montene do not have to worry about not being able to see.

If the previous light crystals that illuminated almost the entire cave were placed by the people of the lost city, then the light in the newly emerged palace should have existed in ancient times, and the technology that could keep the light source for an unknown number of years made Meng Tian can't help but have an admiration for the ancients.

I don't know if it's because of a certain habit of people, but in the end, Meng Tian chose a window that was almost attached to the rock wall from the inside.

The three of them leaned on the rock wall and easily climbed the window several feet high, but as soon as they entered, they were startled by what was in front of them.

It turns out that this palace is only half seen from the outside, but it is indeed complete from the inside... It's just a glass wall-like existence instead of the rock wall to divide it, and the building structure on the other side of the glass wall is clearly visible, but it is filled with rolling rapids, and the glass wall is to divide the two worlds of water and drought.

The light in the palace was even darker than outside, and the water across the wall looked a little gloomy and mysterious, a sight that the three had never seen before, and they thought that such a picture might only appear in a human dream.

"What is this..."Su Fei put his palm on the glass wall, and the fish in the water world opposite him were shuttling among the buildings from time to time, which made him feel very magical.

"It should be a ban...?" Xiao De's knowledge is actually not extensive, so he can only guess about it.

However, Xiao De's guess was correct, this was indeed a layer of prohibition, which wrapped the entire underground palace ruins in the cave, and part of this palace was coincidentally squeezed out of the prohibition under the action of the earth's crustal movement, and there was this wonder that several people in Montene have seen now.

"Then why is there water?" Su Fei felt that Xiao De's words were more reasonable, so he asked another question.

"This is Shujiang. "I am very sure of this Xiao De, because this lost city is built on the Shujiang River, and the only water source nearby is naturally the Shujiang River.

"That's not right..."Meng Tian was indeed a little puzzled when he heard this, he calculated the general direction of this place by calculating the previous itinerary, and it was indeed the Shujiang River, but the direction of this water flow was wrong... It's the exact opposite of the direction of the Shujiang River!

"You mean the flow, right? Xiao De looked at Meng Tian with a smug look that he had expected a long time ago, and explained in a playful manner.

It turns out that although the Shujiang River flows roughly from northwest to southeast, I don't know what the reason is that there is a rather powerful reverse undercurrent at the bottom of some sections, and the closer you are to the source of the Shujiang River, the more such sections there are, and the Lost City happens to be in such a section.

"In other words, the upper layer is downstream, and the bottom layer is countercurrent?" Su Fei was shocked today, but now he is not too surprised.

"I see..."Meng Tian maintained his usual indifference, but it was the first time he had heard of the fact that there was an undercurrent in this Shujiang.

"You don't usually go out of the house, hehe. Xiao De was quite satisfied when he saw that the two of them looked like they were being taught, in fact, he had only heard about this undercurrent when he came to this labyrinth.

"I said don't ...... you kid Ouch, I'll wipe it!" Su Fei was very dissatisfied with Xiao De's behavior, but just as he was about to say something sarcastic, he saw a foreign object coming, and he turned his face to look at it and was suddenly startled!

It turned out that the forbidden one swam at some point and a very large fish beast swam in at some point, and this strange beast squeezed the surrounding buildings to pieces one by one, and opened a huge mouth of blood basin the size of a room and pounced towards Meng Tian and the others!

And Xiao De, who was warned by Su Fei, reacted half a beat slower, and when he turned his face, he had already seen the entrance of the esophagus of the black hole of the alien beast, and his face was a little pale!

"Bang!" "Poof..."

The impact of the fish beast made a loud noise on the ban, but the three people who were only a few steps away were not attacked by it...

The alien beast did not break this layer of prohibition, it turned out that it seemed to have infinite strength, but in fact it was just a low-level fish species, and its strength was similar to that of a new master, which brought Su Fei a false alarm...

"It's brewed, scaring the old ......?!" Su Fei felt a pressure of energy that could walk in four stages, he originally wanted to say that this strange beast actually had such strength, but after wiping his forehead, he saw a scene that made his face change greatly!

And before Su Fei's face changed drastically, Meng Tian's energy pressure had already erupted out of his body!

In addition to the sound of the alien beast hitting the prohibition, an extremely subtle sound sounded at the same time, which was the sound of the weapon entering the flesh!

"Old Xiao?!" Su Fei's previous words were interrupted, and what blurted out again was a shout for Xiao De!

A sword was stuck in Xiao De's heart, sting it in half, and the figure was almost like an afterimage, and it had already dodged away!

Everything that happened just now was seen by Meng Tian, and that person's speed was not much worse than his own! He pulled out Haochen extremely quickly, but he was only on guard and did not chase after him... Because he knew that he would not be able to catch up with this person in a short time...!

This sword is in the center of the mouth... Unless Xiao De is different from ordinary people, his heart grows on the right side, otherwise he is afraid that he will definitely die...

Meng Tian glanced at Xiao De quickly in the midst of vigilance, and his brows couldn't help frowning...

......
