Peerless Taoist

Tan Demon Immortal recalled, "Back then, I was merely a Daffodil at the riverside, because there was an expert cultivating by the riverside. I got a little bit of spiritual energy, so I evolved into a demon body. I was able to cultivate. When that expert enlightened me, part of his memories fell into my mind. Thus, I was able to recall some clues. He seemed to be hiding something, and under the influence of curiosity, I found this place."    

Lu Yu asked, "What did you find here?"    

"There's an independent spatial zone below, but it's very dangerous down there. Even I don't dare to dive into it. Master, although your strength is profound, you'd better not go down, just in case!"    

Tan Demon Immortal seemed to be very afraid of the things below, and had some resistance. "I have no way to find the secret inside. However, the thing that Daoist Xuanxiang, who enlightened me back then, had to hide must definitely be something extraordinary. It might even be a peerless treasure! "    

"In order to prevent others from discovering me, I moved the entrance of Water Immortal Dao Sect here. I also built this place into a forbidden area. He only felt that it was a Purification Pool and did not dare to forcefully barge in. Then I can keep this secret a secret."    

He told Lu Yu everything he said, then stood up and prepared to see Lu Yu's reaction.    

"That's right. You didn't lie this time. But since you are already here, there is no reason not to go."    

Lu Yu coldly harrumphed and retracted his killing intent. He then casted the Earth Crossing Technique and entered the underground of the pond.    

As soon as he entered the pond, he felt the temperature of the pond drop drastically.    

The Purification Pool had absorbed the surrounding spiritual Qi of Heaven and Earth. When soaked in it, it would give people a warm feeling. However, as soon as he entered the ground, he felt a strong Yin Qi surround him from all directions, making him shiver.    

"There is no dragon vein underground."    

Lu Yu felt the difference in his heart.    

Lu Yu had seen the mountain chosen by the Water Immortal Dao Sect from the outside. It was an excellent treasure land. Almost every mountain range here had a good dragon vein buried underneath it.    

However, there was nothing underneath the pond, only endless darkness.    

After diving for a few thousand meters, Lu Yu suddenly felt the resistance below disappear, and he fell from the sky.    

Fortunately, he was agile. As soon as he landed on the ground, he stood straight.    

In front of him, everything suddenly became clear.    

In the depths of the pitch-black underground, there was actually a huge and towering city wall hidden!    

This city wall stood at the bottom of the mountain, and Lu Yu fell down from the crack above. The surrounding space was an extremely spacious cave, and on the stone wall... There were dark grey stone bricks on the wall, and it was obvious that someone had lived here before.    

Lu Yu looked around, but he was incomparably shocked in his heart.    

This city wall was hidden deep underground. It only revealed a region, like a phoenix feather or a qilin horn, but it was enough to tell how magnificent the entire wall was.    

Lu Yu used the Spiritual Sense to look around, and then frowned.    

His Spiritual Sense was actually bounced back by the wall!    

Lu Yu's current soul was extremely powerful. It was unbelievable that his Spiritual Sense could not penetrate the wall.    

"Master, this is the ruin I found earlier. Unfortunately, I tried my best, but I still couldn't get in." Tan Demon Immortal appeared behind Lu Yu at this time and said.
