As expected, after his body descended to a very deep position.
He found a clue.
There was actually a small hole in the stone wall in front of him.
Not big. It was very irregular, but it was enough for an adult to pass easily.
Mu Chen secretly heaved a sigh of relief in his heart. He swam into the water hole under the faint light of the stream.
Then, Mu Chen followed the cave like an agile fish and swam forward.
This underwater cave was very deep, almost bottomless.
Mu Chen was like a small water particle, wandering around in the cave!
The entrance of the cave was very big at first, but after Mu Chen swam for a distance, he was a little embarrassed.
There was a small passage in his line of sight.
This was the only way forward.
However, the diameter of this passage was only about the size of a huge bucket, and it was not in a regular shape.
"Let's go all out!"
Mu Chen estimated how long he would hold his breath.
He had already been underwater for a minute. Although he was very confident in his lung capacity, he was about to reach his limit.
If they couldn't pass through the hole, they would drown here.
It was impossible to return. After all, the distance to this place was too far.
Mu Chen did not want to become a laughing stock in the Immortal Martial World and become the first player to drown.
Then, Mu Chen slid his hands slightly. With the help of this weak pushing force, he slowly approached the hole.
The water flow here was very slow, but it was still flowing.
If he wasn't careful, there was the danger of hitting the rock wall.
Therefore, Mu Chen could only place his left hand on the rock wall at the side to stabilize his body.
Then, his right hand moved slightly, controlling his body to enter the cave.
This action seemed very easy, but it was not.
In extremely deep water, not only did he have to hold his breath, but he also had to pay attention to the pressure nearby.
Right now, Mu Chen felt as if there was a heavy stone pressing down on his body. It was very uncomfortable, very uncomfortable.
However, for the sake of the Nine Yin Scripture, Mu Chen forcefully suppressed this state.
His body moved, and his body nimbly shuttled through the hole.
It was strange. As soon as he left the cave, Mu Chen immediately felt the pressure around him decrease greatly.
He loosened his body, then slid his hands and floated up to the surface of the water.
The oxygen in his chest was almost completely squeezed out.
A few seconds later, Mu Chen resurfaced.
After taking a few breaths of fresh air, he wiped the water off his face and opened his eyes to look around.
At a glance, he could not help but feel that nature was a divine work.
This was a cave formed by the hot weather. In the sky above this cave, the roots of some trees drooped down.
In addition, there were also some finger-sized specks of light that seeped through the cracks in the rocks.
It dispelled a small portion of the darkness in the cave.
"Crash!"
Mu Chen's figure moved and he went up the rock from the water.
Then, he took off his pants, wrung the water droplets dry, and put them on.
He observed the surroundings, but the light was too dim for him.
He could only open his Backpack and take out the lighter that he had prepared earlier.
These were bought according to Quan Zhen Sect's agreement. 50 gold coins per stick was enough to burn for half an hour.
The lighter was placed in the System Backpack and was not soaked by the cold river water.
It was lit at this moment, and it was emitting a warm, weak, yellow candlelight.
Mu Chen carefully placed the lighter on a plate.
Then, he took out a lot of materials from his system Backpack.
There was wood and some flammable things.
He wanted to light a bonfire here to help illuminate the place. Otherwise, with the weak light of this torch, it would be too embarrassing.
The bonfire was quickly lit up. The oxygen here was very sufficient, and there were also some ventilation holes, so Mu Chen did not need to worry about the lack of oxygen at all.
As the bonfire was lit, Mu Chen finally started to look around the area.
He clearly remembered that in the original novel of The Condor Heroes, the Nine Yin Scripture was discovered by Yang Guo and Xiao Longnu.
It was carved on the stone wall. The two of them had extraordinary comprehension abilities. It didn't take them long to comprehend it.
Then, in this Immortal Martial World with the Condor Heroes as the background, would the Nine Yin Scripture be carved on the stone wall like the original work, waiting for the fated person to discover it?
