Chapter 868 Valley, dark river!

Seven days later.

Wei Hong stood on the flying sword with his hands behind his back, flying away at a moderate speed.

After a few days of consolidation, he began to explore the secret realm.

Following the progress of the last exploration, he began to slowly search the edge of the inner domain. A few dozen miles ahead, there was the intersection of the inner and outer domains.

At this time, Wei Hong raised his eyebrows slightly and said to himself: "Huh? Have you discovered something again?"

It turned out that a paper man sent him a message through his mind, saying that there was a strange discovery.

Wei Hong, like last time, directly sent six paper men to explore together.

He didn't expect that the paper man would make a discovery so soon.

Although he didn't have much expectation in his heart, Wei Hong would not turn a blind eye.

So he immediately turned around and flew towards the paper man in the north.

Soon, he flew over a rift valley.

This rift valley was not very large, only five or six miles long and about seven or eight feet wide. The whole was flat on the ground like a wound.

On both sides of the rift were dark rock walls, which were as sharp and straight as a knife, extending deep into the ground, with deep ravines and bottomless valleys.

Wei Hong looked down from mid-air and saw that there were lush forests on both sides of the rift, and the rift cut off part of the forest. Even if he looked down from the air, he could not see the bottom of the valley.

The rift seemed quite dark, and even the sunlight could not penetrate it.

At this time, a paper man was standing at the edge of the rift.

Wei Hong immediately pressed the sword light and came to the sky above the paper man.

After he came to the top of the rift, he felt a series of sharp and strong cold winds blowing continuously, and it seemed that he heard bursts of roars in his ears, and at the same time, a cold breath came from the bottom of the valley.

Wei Hong looked down and saw that there were some strange vines growing on both sides of the dark rock wall, and there was nothing else, and there was no abnormality.

"Is it here?"

Wei Hong frowned slightly, staring at the bottom of the valley.

In fact, he had already sensed something strange without the paper figurine answering.

It was just that the strangeness came from the depths of the valley, not from the surface.

After a brief thought, he extended his powerful spiritual sense directly toward the rift.

Considering that there should be no monsters in this secret realm that could threaten him, he dared to do so.

But after a moment, Wei Hong's face became surprised and strange:

"It's so deep?"

Even though his spiritual sense had been extended to the limit, it still had not directly explored the bottom of the valley.

Obviously, the depth of this rift had exceeded his expectations.

In this way, his interest was aroused.

"Interesting, is there really a secret underground?"

Wei Hong raised his eyebrows slightly, but did not hesitate at all.

He first waved his hand to let the paper figurine leave, and then flew slowly down to the bottom of the valley.

Since this place was a little unusual, he naturally had to explore it carefully. Maybe there would be some unexpected gains, anyway, it would not waste any time.

With this idea in mind, Wei Hong began to fly slowly downwards.

As he flew downward, he could see only dark rock walls on both sides. There was nothing there except some strange vines hanging on the rock walls.

Gradually, he began to go deeper and deeper into the valley.

As Wei Hong continued to go down, the dark rock walls on both sides gradually became moist. First, a layer of fine water mist appeared, and then the entire rock wall began to drip with water drops.

He could clearly feel that the moisture in the air suddenly became thicker.

And at this time, Wei Hong could already hear the faint sound of water flowing from the bottom of the valley.

"Water sound? Is there an underground river underneath?"

After hearing the sound of water, Wei Hong was refreshed.

Obviously, this meant that he was close to the bottom of the valley.

Sure enough, after flying down for a while, the sound of water flow suddenly increased a lot, and then he looked down and saw a layer of faint water light.

The next moment, Wei Hong flew above a two-meter-wide underground river.

The source of this underground river is unknown, and only a small section is revealed at this time. It flows through the rift valley, flows eastward for several miles, and then flows back into an underground cave, and then disappears.

He looked carefully and found that the water of this underground river was very clear, and only four or five meters deep, and the bottom of the water could be seen at a glance.

At this time, it was not very dark at the bottom of this rift valley, because there were some fungi growing on the rock walls on both sides, and the surface of those fungi emitted a faint fluorescence, which directly illuminated the valley bottom.

Wei Hong was not in a hurry to observe the surroundings at this time, but said to himself with a little surprise: "It is more than thirty miles deep, no wonder my spiritual sense can't reach the bottom."

When he came down, he had already silently counted the depth, and finally found that the depth of this rift valley was about thirty-two miles, so his spiritual sense could not explore it to the bottom.

It was really surprising to Wei Hong that there was such a rift valley with a depth of more than thirty miles hidden in this inner domain.

It was also because of this that he became more serious.

For the sake of caution, Wei Hong quietly released the spiritual shield, then began to look around and observe carefully.

He saw that the area under the rift was not small at all. Starting from the two sides of the underground river, the rock wall seemed to have been dug out a layer, so there was a space more than two feet high and hundreds of feet wide.

There are no strange rocks in this valley bottom area, but it seems very flat.

However, because of the underground river, the ground here is also very moist, and there is a layer of moss attached. Obviously, no one has been here for many years.

Wei Hong looked around, but did not find anything unusual.

He frowned slightly, but did not express any opinions at the first time. Instead, he expanded his consciousness again and prepared to explore it carefully.

In such a slightly dark place, the consciousness is much more useful than the naked eye.

After a while, Wei Hong paused and said, "Hey, I found it!"

He subconsciously looked to the left, but did not see what he saw in his consciousness at the first time.

So he immediately raised his foot and walked slowly to the left, and directly cast a light spell to illuminate the area in front.

In his sight, all he saw was a dark rock wall and wet ground.

Da Da Da!

Even though Wei Hong slowed down his footsteps, he still made clear footsteps in this quiet environment.

After walking for a while, he came to an uneven rock wall.

He looked at the rock wall in front of him quietly, frowning, and his eyes flashed with an inexplicable light, as if he was hesitating about something.

Because he used his spiritual sense to detect that the abnormality was in the rock wall in front of him.

If it weren't for his spiritual sense increasing a lot after breaking through to the Jindan stage, he might not be able to find the abnormality.

After hesitating for a moment, Wei Hong stretched out his right hand and slowly touched the rock wall!
