After another two days, the aura is still draining, and there is still no sign of stopping!

"Black Devil, Young Master, I'm afraid I'm not breaking through!" In the past five days, the White Devil's worries have not stopped.

"This really doesn't look like a breakthrough, such a huge amount of aura, let alone a distraction period breakthrough, even a group of Mahayana stage masters don't need so much aura to break through.

Moreover, the situation this time is very different from the past, maybe the young master is just doing something else!" the dark devil speculated.

But it was hard for them to imagine that they needed so much aura, but they didn't dare to disturb Cheng Yu, after all, this time was the most taboo to disturb.

"I hope the young master will be fine!" the white devil nodded, but he was still at ease.

After all, they are recovering very well now, everything depends on Cheng Yu's help, and at the current speed, it won't be long before they can appear in the outside world.

If something happens to Cheng Yu, they may have to stay in this place for the rest of their lives!

Cheng Yu looked a little tired, in five days, I don't know how much spiritual energy was sucked into the dead wood, but this dead wood is not saturated!

Whew! Cheng Yu suddenly stopped the input of spiritual energy, and sat on the ground panting, looking at the dead wood in his hand with an incredible face!

"It's terrible, this thing is terrible! I've actually put a whole spiritual vein into this dead wood. But this dead wood has not been sucked up yet, is this a god or a vampire?" Cheng Yu was really scared by this dead wood.

He didn't know how much spiritual energy he needed to absorb this thing, so he lost a spiritual vein all of a sudden, and it hurt to think about it!

"Forget it! This thing is not raised by ordinary people, these spiritual veins of oneself are pressed to the bottom of the box, if they are all used to absorb this thing, but in the end they get nothing, then the loss is too great. Cheng Yu had no choice but to give up.

After all, these spiritual veins have given him too much help, and he will need these spiritual qi in the future, so he doesn't dare to use such valuable things to do experiments.

Comparing this dead wood that had absorbed the aura with the other two, it was found that this dead wood was greener than the other two, but other than that, there was no difference.

"Alas, it cost me a whole spiritual vein, and it turned out to be such a little change, this thing is not an ordinary pit!" Cheng Yu shook his head helplessly, and finally had to put away the dead wood and walk out of the cave.

As soon as I got out of the cave, I saw that the black and white devils were not far from the entrance of the cave!

"Why are you here?" asked Cheng Yu.

"Young Master, are you coming out? We saw the aura inhaled outside your cave and knew you were inside. But seeing that this aura transfer was a little abnormal, I was a little worried, so I kept guarding here, for fear that the young master would have an accident!"

"Thank you, don't worry, I'm just doing an experiment, but unfortunately it failed!" Cheng Yu said with some emotion.

"I don't know what kind of experiment the young master is doing, and it takes so much aura to consume?" asked the black and white devil very curiously.

"It's the holy relic you gave me, take a look, is there any change?" Cheng Yu didn't hide it, anyway, one of them was taken from them, and he took out the dead wood that had absorbed the aura and handed it to the two of them.

"Young Master means that all those spiritual qi have been absorbed by this holy relic?" the white devil took the dead wood and observed it carefully, and then handed it to the black devil.

"Yes, but this thing is so terrible that I have injected the aura of a whole spiritual vein into this thing, but I haven't let it suck it up. ”

"This holy relic can actually absorb so much spiritual energy, presumably in the entire cultivation realm, only the young master would be so extravagant, but I never knew that this holy relic could absorb spiritual energy, and it could absorb so much!" said the black devil very unexpectedly.

In the past, when the holy relic was in their hands, they had not entered the aura, but they tried to refine it, but unfortunately they did not succeed.

"You didn't know it could attract aura?"

"Yes, we've only refined it before, but it didn't work!" said the White Devil, shaking his head.

"It's really weird, but it's so strange that so many people worship it as a sacred object. Do you think the Xuantian Sect will know the secret of this holy artifact?" asked Cheng Yu.

"I don't know, right? Because the fact that Xuantian Sect enshrines holy relics has always been known to the outside world, but no one in their Xuantian Sect has received magical powers. If they knew the secrets of the holy relics, then there would definitely be someone in the Xuantian Sect who had magical powers!" the black devil said.

"Yes! It seems that it is not a simple matter to solve the mystery of the holy relics!" Cheng Yu nodded, a little disappointed in his heart.

If Xuantian Sect really knew this secret, maybe he would be able to go to them to find out this matter when he became stronger. But now it seems that this is unlikely.

"Yes, we haven't found anything special about this relic for so many years. However, this holy relic seems to have become greener than the original after absorbing the aura, and maybe it won't take long for the young master to be able to crack this secret!" said the white devil.

In fact, they also want to know the secret of this holy relic, but unfortunately, this holy relic is such a piece of dead wood, and there is no mystery, it is really difficult to understand this thing.

"Okay, you guys rest, I'll go out first!" Cheng Yu nodded and left Shanhetu and returned to his room.

Cheng Yu unknowingly spent five days in the mountains and rivers map, but they were in a hurry. But fortunately, there were guards in each small courtyard, and they learned that Cheng Yu had been in the room and had not come out, and they just thought that Cheng Yu was in retreat again.

Although he was in a hurry, he didn't bother him!

"Senior brother, I saw that those guys were all released by you, and I thought you asked what treasure you asked, and ran out to hunt for treasure alone?" Seeing that Cheng Yu finally came out, Xinluo said with a smile.

"If it's really a treasure, won't you come along?" Cheng Yu said with a smile.

"Haha, of course, we also asked them, I don't know what Senior Brother Yu asked?"

"Since you've all asked, why are you asking me for?"

"I'm afraid that we forgot something and didn't ask, after all, junior brother, you think more than us, and you must ask more carefully than us!" Xinluo said.

"Is this a sycophant?" Cheng Yu said with a smile.

"How can this be said to be sycophancy? We call this an exchange of opinions, and it is definitely more clear for a few people to think about the problem than one person!" said Xinluo with a smile.

"What's so hard to think about, that's all there is to it!"

"Of course there are some things I don't understand, that guy told us that they are looking for some kind of artifact, junior brother, have you heard of this thing?"
