The clear sound of running water woke up Yu Lang, not only hearing the sound of running water, he could even hear the coldness of running water, the faint smell of flowing water, and even the sweetness of the entrance of flowing water, the five senses were countless times stronger than before, and faintly reached the synaesthesia state depicted in the book.

Yu Lang sat up straight and touched his smooth abdomen in disbelief, the previously shocking wound was actually healed as before, and the limbs in his body were filled with incredible strength.

Not far away was a smooth stone, on which lay a creature that I didn't know if I could call a human or not. The silhouette is that of a person, but the back is covered with a thin layer of scales.

Yu Lang felt that there seemed to be liquid left at the corner of his mouth, and he raised his wrist to wipe it, but it was actually red blood. He suddenly realized something, waded over to the man, and shouted, "Yu Dan, Yu Sheng!" ”

Yu Dan, who came to his senses, was still very weak, and he breathed a sigh of relief when he saw Yu Lang's lively appearance: "Brother Lang, you are not dead, it's good, my blood is still a little useful after all......"

Yu Lang was no longer hypocritical, and made a big gift to Yu Dan: "Thank you for saving your life." "If it was usual, if he knew that he had drunk human blood, Yu Lang would only be disgusted, and he felt that it was better to die than to live like this. After truly experiencing the horror of death, the only thing left in his heart was happiness.

Yu Dan cheered up: "Brother Lang, don't worry, I will be able to make up for this blood soon, I can't die, if I can, I really want to taste what death is like." ”

"You, you ......" Yu Lang looked at the scales on Yu Dan's body, wanting to ask something, but he didn't know where to start.

Yu Dan smiled: "I, not born or dead, half dragon and half human." ”

"Half-dragon, half-human?"

"When you were dying, I remembered many things." Yu Dan's expression was a little sad, "A hundred years ago, I had a very short happy time, accompanied a monk named Chen Xuanzang to many places, and made many interesting friends. ”

Yu Lang's eyes widened: Learning from the West?

"Chen Xuanzang and I walked into the desert and met a group of strong men, those people are very high in martial arts, I can't fight them, I can't protect him. Later...... "Yu Xuan pondered for a while, his face looked pained, "Later, a man named Goku appeared, and made a black iron rod - that black iron rod seems to be the same material as your short knife, and Goku is extremely powerful, and he repelled the bandits with the power of one man......"

"I can't think of anything from then on, this part of the memory itself is also very broken, I only remember that I must protect that friend named Chen Xuanzang, he is very important to me. You have an aura similar to him, so since you shared my food in prison, I always wanted to protect you, but I don't know why I am so weak......"

Yu Lang was shocked when he heard this, Chen Xuanzang did have his own person, and there was also a record of a Hu man named Wukong in the wild history, and according to legend, this person accompanied Chen Xuanzang all the way to complete the important task of learning from the scriptures. Later, Chen Xuanzang returned to the Tang Dynasty to accept Li Shimin's reward, but no one ever mentioned the Hu man named Wukong.

Yu Sheng suddenly screamed in pain, the scales covering the surface were absorbed into his body, and he slapped the boulder in the water.

Yu Lang didn't dare to disturb him silently, and stepped forward to help, and the always indestructible grinding stone knife slashed at the stone, leaving only a shallow mark.

The boulder finally cracked after dozens of blows, and due to the stress concentration effect, the crack fell apart not long after.

Yu Dan covered his head, as if in great pain, and pointed to the passage under the boulder with his left hand and said, "What you want is here." ”

"Where are you going?" Yu Lang stopped Yu Dan, who was about to leave, "Your injuries are not healed yet, you have to recuperate for a few days." ”

Yu Dan looked pained: "I can't stay here longer, I have to go to another place to complete some things." ”

"Do you have to go?"

"I have to go." Yu Dan's tone was resolute.

Yu Lang no longer stood in his way and made the way.

Yu Dan looked back and smiled: "You don't have to worry, I can't die, eternal life is God's punishment for me, one day if I really die, you should be happy for me." There will be a period later. ”

Yu Lang was a little distracted, and Yu Sheng was gone.

Only the sound of the water remained, and nothing seemed to have happened.

Yu Lang stood in a daze for a long time, but he still couldn't figure out who Yu Dan was, why every time he saw him, he was always in pain, and he never seemed to have a happy time.

I don't want to think about it, I will always come when I should come, and I can't avoid it if I am not in a hurry, so I will let it be.

Where the boulder was broken, a hole appeared, and according to Yu Dan's statement before leaving, there would be something he wanted in the cave. Yu Lang recalled that he had spent so much effort trying to get the place for the Moon Washing Academy, but now that the source has been lost, and I don't know how many times I have been in a coma, how can I compete for the first place in the big competition?

Could it be that this cave is the place where the scriptures are washed and the marrow is removed? Yu Lang's heart suddenly rose to his throat, this place was originally a mountain range that belonged to the Moon Washing Academy, and the test center for the final round of Dabi's assessment was also located here......

Yu Lang picked up the grinding knife and carefully walked step by step to the depths from the cave entrance, the further he went, the less light penetrated from the cave entrance, although Yu Lang's eyesight has also improved greatly compared to before, but the cave has nine curves and eighteen bends, and it is impossible to see the end at a glance.

The cave was pitch black, and the ignition tool he carried with him was lost again, Yu Lang simply closed his eyes, and hit the rock wall with a grinding knife every few steps, judging the structure of the cave by echo, and groping for the direction of progress.

There are many forks in the cave, and even if he uses the method of listening to the sound and identifying the location, Yu Lang is still lost. The environment here is dark and closed, the air is thin, and it is easy to panic if you get lost. Yu Lang actually touched a dead body in the dark, and his heart was even more panicked.

"No, since Yu Sheng led me here, this must be a way of life and not a way of death." Yu Lang relied on his trust in Yu Dan to regain his composure.

Yu Lang stopped, took a few deep breaths, and completely relaxed his body. He felt something in his chest that felt a pull! Yes, since Dabi uses the "source" as a prop, does it mean that the "source" is inextricably linked with the location of the menstrual washing and marrowing?

Yu Lang hurriedly took out the only remaining source, followed the weak traction, and slowly moved forward in one direction.

I don't know how long I walked with my head bored, Yu Lang felt tired and thirsty, and even dizzy from lack of oxygen, just when he was about to despair.

A little light finally appeared in the boundless darkness, and that little light must be the exit!

Yu Lang lifted his strength, walked a few quick steps, and finally walked out of the hole, he sat down on the ground, squinted slightly, greedily breathed in the fresh air, and rejoiced that he had escaped death again.
