After five thousand years of cultivating immortality, he was picked up and cultivated by Heaven.

The two of them observed for a long time but found no danger. The only thing that made people feel strange was that they had been here for so long and did not find a flying animal in the sky, such as birds, butterflies, falcons, etc.

The sky is clean, there is nothing.

Even in the woods, there were no traces of animals, which was really strange.

The two realized that staying in the forest was not a good thing. After flying down, they originally wanted to use the spirit boat to travel and save their spiritual energy to avoid any danger.

It turned out that the spirit boat could not be started, and the flying sword could not be used. Song Yu's cultivation was now suppressed to the late stage of Qi training, so naturally he could not fly with the sword.

In the end, the two of them used magic talismans and air control skills to get on their way.

Bai Wuchen sensed that the teleportation talisman board in his dantian could still be used, but the distance was greatly reduced. He felt that it would be good to be able to teleport five miles.

It seemed close, but the two of them walked for an hour and still didn't arrive. At this time, they came to a river in a valley, and the surrounding area was relatively empty.

The two decided to rest here for a while.

In the river, Bai Wuchen discovered a group of colorful fish. This was the first time they found traces of animals in this secret place.

He thought there were no other living things here except trees.

The scenery here is nice. The two simply arranged a few formations, and then began to boil water and make tea.

They used their own water, fearing that there might be something wrong with the water in the secret realm.

So far, they have found no traces of anyone living there, so they cannot tell whether this place was formed naturally or was created by powerful forces.

However, after walking for so long, I didn't meet anyone. There were at least tens of thousands of people coming in, which had to be strange.

Maybe it's because the place is so big that I didn't meet anyone else.

In the vast green sky and earth, it felt like they were the only two people left.

Fortunately they were together, otherwise his autism would have recurred.

"Don't worry Wuchen, I'm by your side."

Considering that Bai Wuchen has been practicing for a short time and has experienced relatively few things, Song Yu can always comfort him in time.

"I'm fine. Fortunately, I have you." Bai Wuchen smiled and took the initiative to hold his hand.

Song Yu was very happy. The atmosphere between the two was just right. Suddenly, his eyes went dark, as if he had suddenly gone blind and could not see anything.

"Wuchen?" Song Yu shouted and pulled Bai Wuchen to his side.

"I'm fine, I just can't see anything. How are you?" This feeling is very bad, like suddenly going blind.

"Me too, I can't see anything. I can't feel anything when my consciousness is outside." Song Yu held his hand tightly to prevent him from getting lost.

"It may be dangerous. Let's find a place to settle down first. I remember there is a mountain not far ahead. Let's go there and open a cave."

The immortal had an amazing memory and a strong sense of direction. Although the surroundings were pitch black and nothing could be seen, the two of them quickly reached the foot of the mountain with the help of their memory.

Afraid of encountering danger on the road, they also took out the flying sword and injected it with spiritual power. They were always vigilant, but they could not see the light of the flying sword.

This place is really strange and weird. This unknown anomaly is the most terrifying thing.

Fortunately, the spiritual power can still be used.

When the two of them were resting by the river before, they checked the area, so they were quite familiar with the mountain.

The two flew to the mountainside and based on their memories, found a suitable place and started to open the cave.

The two of them cooperated tacitly, and even in the dark, they were not greatly affected.

Soon a cave was opened, and then Bai Wuchen heard a rushing sound from the direction of the river, as if something was swimming up from the river.

The two held hands and immediately entered the cave.

After sealing the door of the cave, they arranged several formations and took out luminous stones for lighting.

I can actually see it this time, but the light seems very weak. You must know that the luminous stone is brighter than a hundred-degree electric light. Now you can only see a little hazy light, and the surrounding is filled with rich darkness.

After taking out dozens more luminous stones, they were able to illuminate a small area around the two people.

Bai Wuchen thought that the isolation stone he had obtained at the ancient battlefield might be useful.

He told Song Yu, and the two took out the isolation stone and placed it at the entrance of the cave.

Bai Wuchen has always used this isolation stone as a brick. It is very hard. He once used this stone to kill a demon monkey.

This type of brick is very large, and it only took about sixty bricks to seal the entire hole.

The two of them spread the remaining bricks on the floor of the cave and sat on them.

"Wuchen, have you noticed that the surroundings seem a little brighter?" Song Yu said suddenly.

Bai Wuchen felt it, "It's indeed a little brighter, and I feel like my consciousness can be released."

"It's true, it just feels like it's being held back."

"Well, I feel that the surrounding aura is very sticky and my spiritual consciousness cannot penetrate it. What on earth is this black color? Can it actually block my spiritual consciousness?"

"Maybe it's the law of this world, otherwise why would it suddenly turn dark? Only the law has this power." Song Yu said, his knowledge was wider than Bai Wuchen's.

"It seems to be getting brighter and brighter." Bai Wuchen's tone was a bit surprising. No one would like this kind of thick darkness.

Half an hour later, the room became brighter and brighter. The two put away some luminous stones. Now the room was as bright as day, without any darkness at all.

The bright environment is still reassuring.

At this time, there was some movement from outside, which made Bai Wuchen's heart twitch again.

The formation they set up in the cave can isolate breath, consciousness and all kinds of movement, but they can hear sounds from outside in the cave.

Their cave is located halfway up the mountain, and the sound comes from the foot of the mountain.

It seemed like there was some giant beast walking at the foot of the mountain. The sound of "dong-dong-dong" was so heavy that the vibrations could be felt in the cave.

The two of them were thankful that no cave had been opened at the foot of the mountain.

Not to mention that it was easy to be discovered, the huge movement alone was like an earthquake, who could bear it.

The heavy footsteps gradually faded away, and after a while of silence, the outside became lively again.

I can’t tell what kind of animal it is, maybe it’s unique to this secret place.

The two of them didn't go out to check. It was pitch dark outside, they couldn't see anything, and they couldn't sense it with their spiritual consciousness. There was no need to go out and take risks.

After the initial nervousness and fear, Bai Wuchen slowly adapted.

On the contrary, Song Yu next to him always had a calm face and didn't seem worried at all.

Even though I am old, my mental quality is really not up to par.

I don’t know when this darkness will recede.

Bai Wuchen had no intention of practicing, so he took out the bed, quilt, and pillow, intending to have a good sleep and recharge his batteries.

He felt that Song Yu was not affected by the secret realm and had excellent psychological quality. He should be able to meditate and practice.
