The width of the corridor is very narrow, and it is estimated that only two people can barely squeeze in at the same time.

Through the Yongdao, you can faintly hear the sound of water flowing inside, it seems that the end of the Yongdao should be an underground river, but I don't know how long it will take to enter the river from here and reach the back mountain.

It was still Shi En who was the first to enter, Mu Yizi and Hu Dai followed, Lu Qingyu was in charge of the back of the hall, and soon the four of them climbed into the corridor one after another.

Due to the limited height, the four of them could only half-squat and move slowly through the corridor, and the speed of progress was extremely slow. This passage, which was only two or three hundred meters wide, was only two or three hundred meters wide, and the four of them squatted for more than half an hour before reaching the end.

As soon as they jumped out of the corridor, Lu Qingyu and the others couldn't help but exhale in unison, and the feeling of shrinking into a ball and moving slowly was really embarrassing.

After jumping out of the road, a river three or four meters wide was displayed in front of Lu Qingyu and others, and there was a raft on one side of the river.

The raft looked very simple, and it was made of a dozen narrow planks simply nailed, which should be the next tool for Lu Qingyu and his party to cross the river and move forward.

"Can this thing move the four of us?" Mu Yizi stepped forward and patted the raft and said with some concern.

Shi En smiled slightly and replied: "Don't worry, don't look at this raft, it's actually very sturdy, don't talk about the four of us, even if there are four more to sit on, it's no problem!" ”

"It's really fake, don't lie, your nose will get longer if you lie!" Mu Yizi muttered very seriously.

Shi En was suddenly covered with black lines, and Lu Qingyu and Hu Dai also covered their foreheads with their hands, and they were really speechless to the extreme.

After a small episode, the nervous mood of the four people relaxed a lot, and soon they all got into the small raft with quick movements.

Shi En reached out, pulled out a penny from the side of the raft, and stood on the bow of the boat to become a boatman.

Lu Qingyu and Hu Dai honestly stayed in the center of the raft, waiting for the voyage, only Mu Yizi restlessly came to Shi En's side, looking at Shi En curiously, it seemed that he wanted to carefully study Shi En's rowing movements.

Shi En was stared at by him, and he hurriedly turned his face sideways, untied the rope on the raft, and set sail with a swing of penny!

Because the channel of the underground river is very narrow and the current is relatively turbulent, it is still very difficult to control the raft, but Shi En is obviously already a qualified boatman, with a small penny in his hand, it was smooth sailing, and there was no collision along the way.

However, Lu Qingyu had already seen through the intention of this goods, and where to let him succeed, he hurriedly dragged him back before he could speak, and glared at him, the meaning of warning was very obvious.

Seeing Lu Qingyu's serious face, Mu Yizi immediately stuck out his tongue and honestly stopped moving.

After twenty minutes of rafting, the river became narrower and narrower, in some places it was barely enough for a raft to cross, and the slope of the slope began to increase, and it was obvious that the group was heading to a lower place.

After turning a few more corners, Lu Qingyu's eyes suddenly darkened, and a huge stone wall appeared in front of him, blocking the way forward.

Lu Qingyu was stunned for a moment, looked at Shi En with a puzzled gaze, and asked:

"What's going on, why is there no way?"

Shi En licked the corners of his mouth slightly at this time, and replied excitedly:

"Haha, little brother, who said there is no way! Tell you to put it, the road, right at your feet! Sit tight! ”

With Shi En's shout, the raft under him suddenly began to speed up, and then rushed towards the stone wall in front of him without hesitation.

Lu Qingyu and the three of them were shocked when they saw this, what is Shi En doing!

But before Lu Qingyu and the others could ask, the raft under them had already risen into the air and fell down rapidly.

It was only at this time that Lu Qingyu discovered that this was a terrain similar to a waterfall, and there was a drop of more than ten meters up and down the river, but it was not real from a distance, as if there was no way out.

The body fell rapidly down with the raft, and the dark stone wall in front of him flashed upwards rapidly, and Lu Qingyu's mind suddenly flashed with inspiration, and he remembered a familiar scene.

When he drifted from the underground rivers of the Jingling Mountains to this Dark Alliance, he encountered a fork in the road.

One of the forks in the road flows horizontally, leading to the valley behind the Black Dragon Mountain, and the exit is above the eldest lady's dragon head spirit pool, while the other is vertically upward, with a huge drop, and it looks a little like a small waterfall.

At that time, because he was anxious to escape from the underground, Lu Qingyu chose the road leading to the back mountain, instead of exploring another river that went upstream.

Could it be that this is the ......

This thought flashed through the lightning and flint, and Lu Qingyu's thoughts had not calmed down, and the raft under him had already fallen into place with a bang.

The water splashed, wetting the bodies of the four people, and then the water vapor filled the air, and the surroundings were blurred.

After more than ten seconds, the splashed water vapor slowly dissipated, and at this time, Lu Qingyu and the others were already in a mess.

With wet hair and looking at the somewhat cracked raft under his feet, Lu Qingyu and the others glared at Shi En a little speechlessly, Shi En spread his hands and smiled.

At this critical time, naturally no one really took Shi En seriously, after all, Shi En was no better. After briefly cleaning up his mood, Lu Qingyu looked up at the surrounding environment.

Sure enough, the environment here is where Lu Qingyu has a sense of déjà vu, which is the fork in the road he once came to. Then, this place is obviously not far from their destination, the mountain behind Black Dragon Mountain!

Shi En shook the drops of water on his head and said to Lu Qingyu:

"Well, little brother, this place is familiar! Last time, you should have passed by here before you met the eldest lady! ”

Shi En emphasized the word "encounter", and Lu Qingyu rolled his eyes when he heard it.

Mu Yizi rolled his eyes, and suddenly said:

"Oh! I understand, Qingyu must have lurked into the back mountain valley from here to peek at the eldest lady taking a bath, right! Oops, I didn't expect our Qingyu to be quite capable, even peeking at girls taking a bath, they can choose such an incisive path! ”

Lu Qingyu didn't squeak, just glanced at Mu Yizi's neck lightly, considering whether to strangle this thing.

Shi En laughed and said:

"Of course, if it weren't for the little brother's unintentional move, we would still be blocked out of the valley and at a loss! By the way, little brother, the eldest lady said, the next time I see you, I will definitely thank you well! ”

Listening to the two accented "good" in Shi En's mouth, Lu Qingyu suddenly had an ominous premonition, he seemed to have gotten on the thief ship......
