Behind a huge rock was a pool of clear water. In the middle were two small springs, and spring water was constantly flowing out of the pool.

Wu Dong knelt in front of the pool and immediately drank it down.

A refreshing feeling spread from his throat to his limbs and bones, an indescribable feeling of comfort.

This spring water was definitely not simple and sweet. There was definitely some kind of strange spirit stone mineral in the underground water network. Drinking it all at once would lift one's spirits. If one drank this water over a long period of time, they would be able to live for a long time and die of a hundred diseases.

Wu Dong looked at the old man again and finally understood the reason why the old man was so energetic.

He pulled himself together, stood up and looked around. He almost cried out in alarm.

This was the place he was looking for, exactly the same as the one Gu drew, except that Cypress Pine Tree was thicker than the one in the painting.

This was where the Daoist Priest Qing Yi had drawn the ancient paintings back then. He had even left a code word on the paintings saying that he had saved the treasures for his descendants.

Just what kind of treasure was it?

It couldn't be this spring water, could it?

Wu Dong was very disappointed. Although the spring water was good, it could not be eaten.

He was lost in thought. The old man had already filled several bottles of spring water and tossed them into the basket.

He pulled Wu Dong up and insisted on him going to his house for lunch.

After Wu Dong rejected him for a long time, the old man did not let go.

The mountaineers were simple and honest. When they became passionate, they would not fake it.

Wu Dong found it a little difficult to refuse such kindness, and finally thought of a compromise.

He still wanted to stay by the mountain spring for a while before heading over to the old man's house for dinner.

The old man shook his head. "You city people are just being hypocritical. These mountains are all trees, what's there to look at?"

The old man showed Wu Dong the way, then picked up the basket on his back and went home first.

Seeing the old man walk far away, Wu Dong started to wander around the mountain spring. However, in this area, aside from the spring water, there were only stones.

Could it be that the things that the green-robed Daoist had hidden for hundreds of years have already been taken away by someone?

Wu Dong was not willing to give up and continued to look for a long time in vain.

Leaning against the trunk of a pine tree to rest, he suddenly thought of something.

The only thing left unchecked was the tree.

He struggled his way up to the top of the tree, but the needles and leaves around him were too thick for anything.

With his last bit of hope shattered, Wu Dong wanted to climb down the tree trunk.

Suddenly, the ground beneath his feet became empty, and for some reason, he fell into a tree.

The whole inside of the pine tree was empty.

A human face, a tree skin.

The dense pine and cypress on the surface was actually a passageway in the middle of the tree trunk.

Wu Dong only felt his vision turn black, and he fell down.

All the bones in his body were broken into pieces, and he even had a lot of skin scraped on his face and arms.

He stood up with a start. Everything was pitch black in front of his eyes. It took him a while to get used to the light.

It was as if he was in a very large cave. In the middle of the cave, there was a dark red stone that emitted a faint light.

Wu Dong smacked his head and remembered that he still had his phone installed. He turned on the flash and finally saw the surroundings clearly.

It was more like a tree hollow than a cave.

The surrounding area was completely surrounded by the roots of the pine cypress, leaving only the tree trunk above them with access.

He walked closer to the center of the hollow tree and found that there was a pool in the middle of it. A dark red stone was lying in the pool, emitting a dark red glow, like a piece of red-hot iron.

Wu Dong touched the water in the pool, but there was nothing wrong with it.

He dared to touch the rock again. It was actually warm.

He bent down again and tasted the water in the sink.

The smell was sweeter than the spring outside the tree hole.

This time, Wu Dong understood. The treasure that the green clothed Taoist had left behind was this big stone.

It was precisely because of this stone that the mountain spring water had spiritual energy, allowing it to extend its lifespan.

Wu Dong used his phone to look at the stone and discovered that it was connected all the way to the bottom of the pond. He did not know how big the stone was.

This was a little difficult. This treasure was a little too big to move!

Wu Dong looked at his surroundings and suddenly had a strange thought. He didn't know how long this pool had been submerged in water, but it would definitely dilute the energy in the stone by a lot.

"Since laozi has encountered a bottleneck in my cultivation, I'll just treat it as bathing in medicine."

With that, he took off all his clothes and jumped into the water.

Instead of feeling cold, he felt a warm current flowing through his body, opening all the meridians in his body and greedily beginning to suck in the energy from the pool.

Wu Dong closed his eyes and started to practice the dragon-body technique.

With the help of the hot spring water, he would be able to continuously break through to the second level.

What Wu Dong did not know was that this stone had a name.

It could provide a steady stream of energy to help in cultivation, but at the same time, it was also extremely overbearing and could cause one's cultivation to go berserk if they were not careful.

There was no sun or moon outside the cave, and the cave had its own universe.

With the assistance of the Ten Thousand Year Flame Stone, Wu Dong successfully broke through the second level of the dragon-body technique.

It was fortunate that Wu Dong's foundation was shallow. If he had used a extreme yang energy's power on the seventh floor or above, it was very possible that his entire body would be controlled by the energy, and he might even be in danger of losing his life.

Wu Dong climbed out of the pool and laughed out loud.

This treasure was really easy to use. If he was given a few more days, he was confident that he could break through a few more levels.

He put on his clothes and climbed out of the tree hole.

No matter how many years pass, this place will not be discovered by outsiders.

Seeing that it was getting late, Wu Dong thought that since he would come here often in the future, he might as well visit that passionate old man next time.

Thus, he quickly descended the mountain.

It took a few hours to get here, and I was tired like a dog.

When he went down the mountain, he had already been reborn. He felt as if he had been reborn anew.

He went back to the curb and found the driver who had brought him there still sprawled out asleep in the taxi.

He knocked on the glass and the driver woke up immediately. When he saw who it was, he couldn't help but complain, "Bro, it's so f * cking hard to earn that money!"

Wu Dong was in a good mood, he handed the half of the money to the driver, and added another two hundred.

The driver immediately regained his spirits and brought Wu Dong back to the city quickly.

When Wu Dong returned home, he found Jiang Xue waiting for him in the living room.

A pretty face drooped as if someone owed her two hundred dollars.

She raised her head to look at Wu Dong. She remained silent, her face still pouting in anger.

Wu Dong did not have time to bother with her, and went to the kitchen to treat himself.

He whistled and cooked, thinking that he would need to buy a long-term car, and every now and then, he would go to the tree hole to cultivate.

If he worked so hard, it wouldn't be long before he could surpass the lordmaster.

Jiang Xue had thought that she would definitely comfort her with this expression of her.

Unexpectedly, he didn't even ask and just ignored him.

He had no idea how much she had suffered today for him.
