Fang Xing has been waiting for an opportunity, and now this opportunity has come!

At the moment when the three-tailed wolf turned its head, a rapid red light hit the three-tailed wolf, its body suddenly stiffened, and Fang Xing took this opportunity to cut off the neck of the three-tailed wolf.

Blood flows!

Xiao Bai, who was lying firmly on Fang Xing's shoulder, looked a little sluggish, the decisive blow just now was the attack launched by Xiao Bai's condensed energy.

"Boom!"

The three-tailed wolf fell to the ground, its pupils dilated, and it was dead.

Fang Xing immediately picked up the dagger and "dissected" the three-tailed wolf, successfully finding the wooden box in the stomach, the smelly gastric juice flowing all over the ground, and at the same time there was undigested human flesh.

Fang Xing wiped the wooden box clean repeatedly, although it still had a strong fishy smell, but it was relatively much better, and he went back and washed it thoroughly.

He looked at the corpse of the three-tailed wolf and lost interest, it was disgusting. However, he thought of the underworld core that Gu Bowen said, although he didn't know what it was, it didn't prevent him from looking for it.

The belly had been ripped open, and nothing resembling the core of the underworld had been found, which could only be in the brain.

The three-tailed wolf has a slightly hard brain, and Fang Xing also took a lot of effort to unravel it, this time the underworld core is very easy to find, and in the brain stem of the three-tailed wolf, a special crystal the size of a quail egg is concluded.

Fang Xing took off the crystal and looked at it carefully, there was no bloodshot on the surface of the crystal, nor was it contaminated with brain pulp or anything like that, it was like a diamond-shaped crystal, showing light purple, and there seemed to be energy flowing inside, which was extremely beautiful.

Fang Xing could feel the surging energy from it, and Xiao Bai's sluggish expression also recovered slightly. However, after Xiaobai glanced at the underworld, he lay down again and shrugged his head. Apparently not much interest in the Undercore.

It's a pity that this thing was promised to Gu Bowen.

Fang Xing secretly sighed a pity, it was naturally impossible for him to make a move to hack the underworld, not to mention that the gains outweighed the losses, Gu Bowen still had an amplification potion in his hand, Gu Bowen who had been injected with the potion was simply a humanoid tyrannosaurus, Fang Xing felt terrible when he saw it, that muscle, tsk!

However, just as Fang Xing was thinking like this, the underworld core in his hand actually dissolved suddenly, and it quickly merged into his hand, and he had just reacted after fusing it.

Fang Xing was stunned, looking at the underworld core that disappeared in his hand, he looked at Xiao Bai with a confused expression, and Xiao Bai's eyes widened, indicating that he didn't know.

"This..."

What about the people who said yes, but now they have disappeared in vain?

What's going on?

This underworld nucleus is not in vain and integrated into his body, is it good or bad?

Fang Xing doesn't have the ability to look inside as in martial arts novels, but he can still feel the direction of energy in his body.

He calmed down and sensed that a huge stream of energy was rising along the meridians, quickly rushing to the location of the skull mark on his arm.

Fang Xing's face was a little ugly, could it be that this damn thing was playing tricks again.

Although Fang Xing borrowed the energy of the skeleton tattoo to fight, it didn't mean that he could tolerate the existence of something beyond his control in his body.

If that dream is real, then these two skull marks are likely to be related to the two old men in the dream, and the origin is mysterious!

However, he obviously guessed wrong this time, when this energy passed through the skeleton mark, the mark actually withdrew all the extended tattoos, and he didn't dare to move.

Skull sigil afraid of the Undercore?

Wrong!

Fang Xing soon discovered that the skull mark was not afraid of the Undercore, but of the force that guided the Underworld Core.

That's ,,, pupil power!

Fang Xing felt that this energy reached his pupils, and suddenly disappeared without a trace, without a trace of remaining.

The next moment, he had a very strange experience, his eyes were crisp and numb with a little itching, and he subconsciously closed his eyes.

When he opened his eyes, he suddenly found that his surroundings were much clearer, you must know that this was a dark night in the wild, and Fang Xing could barely see the range of ten meters in front of him with the help of moonlight.

But now Fang Xing found that he could see everything within twenty meters clearly, as if he was not affected by the darkness.

Is this a weakened version of dark vision?

Fang Xing was a little surprised, this was really an unexpected gain.

At this moment, he finally figured out why the Hades Nucleus would automatically dissolve, and it was obvious that the Yin and Yang Pupils needed the Hades Nucleus.

Fang Xing knew that this should be the ability that the Yin Yang Pupil fed back to him. He hurriedly immersed himself in his heart and carefully sensed the changes in his yin and yang pupils.

He was shocked by the answer!

That small piece of lilac underworld core was actually converted into two pupil powers by the yin and yang pupils!

The division of pupil power was also arranged by Fang Xing himself, after all, there were not many people in the world who knew the existence of pupil power, so he divided it by share in order to facilitate the distinction.

He divided the pupil power that the yin and yang pupils can hold into ten parts, and the pupil power automatically generated by the yin and yang pupils every day is about 0.1 parts, and only 0.1 parts are used to resist the tattoo attack.

He only produces so much pupil power every day, and spends so much pupil power every day, and his pupil power storage has always been very small, which is also the reason why Fang Xing basically doesn't use yin and yang pupils.

Now the Underworld Core has brought two pupil powers to Fang Xing, which means that this is his 20-day accumulation!

It's not as simple as one plus one, because he spends almost the same amount of pupil power every day, and even after 20 days, he can store no more than 0.2 copies of pupil power.

That's the real surprise!!

He hadn't figured out other uses of pupil power yet, but it was certain that using yin-yang pupils would definitely require the consumption of pupil power.

"Already fixed it?" Gu Bowen trotted all the way and finally caught up, panting.

"It's solved, but I won't give it to you if I have a useful core. Of course, since the Underworld Core didn't give it to you, I won't ask for your potion. Fang Xing said.

"Okay." When Gu Bowen said this, Fang Xing actually saw a flash of disappointment in Gu Bowen's eyes.

What's the situation?

Fang Xing naturally didn't know, Gu Bowen obviously saw that Fang Xing was not a powerful Underworld Beast Hunter, it was very likely that he had just become a Underworld Beast Hunter and didn't know enough about the importance of the Underworld Core, if Fang Xing really traded with her, she would simply make a lot of money.

"You took the Underworld Core, I want to take back the corpse of this Underworld, after all, I have to have an explanation." Gu Bowen said with a pout.

"No problem, you take it." Fang Xing waved his hand very happily.

Naturally, he didn't have any opinions, and he wouldn't ask for the corpse of the three-tailed wolf, and he wasn't a scientific research expert, so he wasn't interested in it.

However, he wanted to take this opportunity to ask Gu Bowen about the information about the Underworld, and if he didn't know the value of the Underworld Core just now, he would still trade potions with Gu Bowen. Now give him ten potions, and he won't do it.

On the way back, Fang Xing is still very happy, this wave of harvest is really worth it! Here's what you can get:

Got the Netherstone Stone.

Get 2 copies of pupil power.

Gain a weakened version of Dark Vision.

Get the news that the Underworld can be converted into pupil power!

and he also successfully promoted to the Guardian Stamper, but compared to the top four, the promotion Stamper is not too much of a benefit.
