After figuring out the reason, Yang Yi immediately gave up the idea of absorbing the metal solution again, but how to find out the metal solution in his body was difficult for Yang Yi. Searching through the memory fragments in his mind, Yang Yi couldn't find the introduction of this crystal, and all the visions he produced when he cultivated couldn't be explained at all.

I can't figure it out, so I just don't think about it, the reason why Yang Yi was able to find the knowledge he could use in the vast sea of memory fragments was because he would never give up easily, and at the same time, he would never be too persistent on a problem, he believed that at a certain time, or when he knew enough about a certain matter, those problems that had stumped him would be solved.

No one is omnipotent, and so is Yangyi.

With an indifferent smile, Yang Yi ended his cultivation and walked towards the outside of the cave.

Does time pass so slowly, or does the time for one's own cultivation get shorter and shorter as you improve your cultivation?

As soon as he walked out of the cave, Yang Yi found that this time the cultivation only took two hours, compared to the previous night at every turn, it was simply the difference between heaven and earth.

Shen Hongyue was cultivating with his eyes closed, after all, the battle in the past two days had cost him too much energy, and the poison of the Hidden Demon Beast in his body also needed True Qi to crack.

Nan Guo Ziqian was still standing at the door of the arsenal and guarding the big hole that Yang Yi knocked out, I don't know where he got it, Nan Guo Ziqian actually picked up a huge magic crystal lamp and illuminated the entrance of the cave.

Yang Yi once again had nothing to do, and waiting for Zhu Aiping to recover was the only thing he could do at this time.

With nothing to do, Yang Yi saw the blood-drenched corpse of the hidden demon beast on the side.

The Hidden Demon Beast has always been considered by Yang Yi to be the biggest threat, after all, it is always in danger, always on guard against possible sneak attacks, for a long time, it is definitely the most tiring and disgusting thing.

This time, the Hidden Demon Beast was completely dead, and in a short period of time, his body had begun to decay, and his shiny skin had become speckled, and many places had begun to fall off.

Yang Yi walked in and looked at the corpse of the Hidden Demon Beast carefully, although he died, Yang Yi was very curious about why the Hidden Demon Beast was able to become invisible, and after being invisible, he couldn't even find out his location in the minds of people.

If you use this stealth skill in battle......

His eyes lit up, and Yang Yi keenly found a crystal.

But how the Hidden Demon Beast is invisible, it can be said that no one in the demigod realm knows, and even Yang Yi may be the first person to get the corpse of the Hidden Demon Beast, and Yang Yi has no clue at all at this time.

Hidden at all times, and even when attacking, they didn't show their figures, so these hidden demon beasts should have been in a state of stealth, but why did they grab the arm of the strongest attack of the hidden demon beast, but the hidden demon beast no longer had any resistance, and the stealth state had been broken.

While thinking, Yang Yi seemed to have found a trace of enlightenment, turned around and picked up the arm that was broken by himself, and Yang Yi observed it carefully.

The thickness of the human arm, with the same oily black and shiny skin as the body, the front end of the arm has a flesh-like paw, and three metal-like claws grow on it, behind the claws, three cracks are neatly arranged on the meat pad, and the length should be the place where the hidden demon beast hides its claws when it does not attack.

Wait a minute.

Why can't the three sharp claws be hidden?

Thinking of this, Yang Yi paid more attention to the metal-like claws, if the hidden demon beasts could even hide this claw, then they would really become the most terrifying demon beasts in the demigod realm, and the silent attack made any master only able to defend and have no way to do anything about them.

With a strong hand, Yang Yi quickly pulled out his claws, wanting to take a closer look.

Burst!

At the same time that the claw detached from the arm, a crunch sounded, and despite being dead, a translucent liquid, completely different from the bright red blood, still flowed down from the wound pulled by the claw.

Yang Yi didn't care about all this at first, all he cared about was this claw, but then Yang Yi realized that something was wrong.

I saw that the translucent liquid was flowing slowly, not scattered and thick, but as if attracted by the corpse of the Hidden Demon Beast, it fell to the ground and flowed directly towards the Hidden Demon Beast.

Yang Yi was a little distracted just now, his eyes swept casually, and he suddenly found that part of the corpse of the hidden demon beast had disappeared again.

Resurrection again?

Yang Yi quickly stretched out his hand and grabbed the corpse of the hidden demon beast.

Cold, the Hidden Demon Beast was still there, and it was indeed dead, and there was no reaction at all, at the same time, the corpse of the Hidden Demon Beast continued to disappear, and there was no stagnation at all because Yang Yi reached out and grabbed it.

Soon, right in front of Yang Yi's eyes, the entire Hidden Demon Beast disappeared, if it weren't for Yang Yi still holding the corpse of the Hidden Demon Beast in his hands, if it weren't for the fact that Yang Yi was still able to see the speckled flesh and blood in this stealth state was not completely hidden, Yang Yi even thought that this Hidden Demon Beast had been resurrected and fled.

Probably has found the key to the stealth of the Hidden Demon Beast, but Yang Yi can't continue, if the Hidden Demon Beast is a mechanical rune demon beast, Yang Yi will definitely figure everything out, but unfortunately this thing is hidden, and he can't see it at all, even if Yang Yi is a doctor, but he is not so powerful at the air, and he can't continue to study at all.

After rummaging through the arsenal for a while, Yang Yi used some containers and chests to collect the Hidden Demon Beast and the translucent liquid.

With the strength of the Shen Hongyue family, it shouldn't be difficult to find some people to study and use in battle.

Everything is in order, a few hours have passed, call Shen Hongyue, Yang Yi is ready to enter the fantasy cave together to see how Zhu Aiping is doing, if possible, Yang Yi still wants to leave this place where there are hidden demon beasts secretly preparing for a sneak attack as soon as possible.

Rustle!

As soon as she entered the cave, Shen Hongyue was fascinated by the azure water droplet-like crystals, and indeed girls don't like beautiful things.

But Yang Yi was different, he heard a trace of the last thing he wanted to hear.

Staring around, Yang Yi saw a fist-sized black figure in a corner.

Without thinking about it, Yang Yi rushed forward quickly, and slashed at this fist-beating black shadow with the flying sword on his body.

Bite!

The sound of a metal clash sounded, and the top-grade magic sword in Yang Yi's hand paused, and this fist-sized black shadow didn't have any loss except for a whitish mark on his back, and he actually didn't pay attention to this attack at all, and continued to be busy in this shadow.

"Yang Yi, what are you doing?" Seeing Yang Yi's strange behavior, Shen Hongyue also took out the medium-grade magic sword found in the arsenal, although he had no habit of carrying weapons with him before, but a series of accidents occurred, which did not make this girl vigilant.

"Iron-eating demon beasts, how did they end up here. Yang Yi seemed to respond, and as if he was muttering to himself, the top-grade magic sword in his hand continued to slash forward, and at the same time, the silver cyclone in his body was also transported and poured onto the top-grade magic sword.
