"Demon core?" Yang Kai was stunned.

From Hu Xian'er's mouth, Yang Kai had heard of the demon core, which was the essence of the whole body of the fierce demon clan, and it was the source of their strength.

The people of the Chixia Sect occupy the connecting passage to the Demon Realm, hunt the demon clan to hunt the demon core, and then improve their strength by refining the demon core.

For the Chixia Sect, this demon core should be regarded as a good thing, and the existence of the demon core in Granny Long's hands was really a little surprising to Yang Kai.

"Mr. Yang, the demon core in my hand is because I completed an extremely difficult task once, and the task reward I received, although the demon core is not a natural treasure, but if it can be successfully refined, its effect will definitely not be worse than that of ordinary spirit herb elixir!"

Refining the demon core requires a special secret method, and the demon core of Granny Long has actually been in her hands for several years, but because the secret method of refining the demon core of the Chixia Sect is too difficult to obtain, this demon core can only survive in the hands of Granny Long until now.

Of course, Granny Long would definitely not take the initiative to inform Yang Kai about this kind of thing.

"Where is that demon core, if that thing is really of some use to me, it is not impossible to spare your life, who told me that this person has always been kind-hearted?" After pondering for a moment, Yang Kai nodded and said.

Yang Kai is not interested in the "Worm Sutra" cultivated by Granny Long, because he is not willing to be like Granny Long, and finally become a nest of poisonous insects, Yang Kai is really interested in the demon core in Granny Long's mouth at the moment.

"Mr. Yang, the demon core is in my residence next door, you wait a moment, I will go and bring the demon core to you now!" Granny Long propped her elbows on the ground, and she slowly got up from the ground with great difficulty.

The wet clothes were worn on her body, cold and cold, if Granny Long was in good condition, it would be difficult for such a situation to affect her at all? But for the now frail Granny Long? The wet clothes made her extremely uncomfortable.

"Ahem, cough, cough ......" In the continuous coughing, Granny Long leaned over? Staggered a few steps.

A feeling of discomfort came straight to Granny Long's heart? She was ruthless, and she neatly and directly tore the already soaked clothes on her body to smash? walked naked to the outside of Yang Kai's courtyard.

If a young and beautiful girl does such a move in front of Yang Kai, Yang Kai will inevitably have her eyes wide open? Have a good look? It's a pity that Granny Long is neither young nor beautiful, she is wrinkled up and down like the bark of a centuries-old tree, and from time to time you can see poisonous insects infesting it.

The ink bamboo rice porridge you just drank? Yang Kai couldn't help but want to spit it out? He originally wanted to go with Granny Long to get the demon core, but now in the face of this situation, Yang Kai can only choose to give up, anyway, Granny Long's residence is next door, with her current state? It is impossible for her to play any tricks in front of Yang Kai.

Between a few breaths, Granny Long was holding a fist-sized sandalwood box in her hand? When she came back again, I don't know if she deliberately disgusted Yang Kai or what? She was still naked.

Taking the box handed over by Granny Long, Yang Kai opened it and took a look.

"This is the demon core?" Looking at the grayish-white hedron the size of a thumb inside the box? Yang Kai couldn't help but sigh.

All of a sudden? Yang Kai felt the golden book that was silent in his mind? Blooming with brilliance again, it seemed that countless air currents poured into Yang Kai's body, and he rushed straight towards the location of the golden book.

This kind of feeling, Yang Kai also had after the death of the woman in red in his murderous mansion, at that time, whether it was a ghost crystal or a yin bead, when they were swallowed by the golden book, the air flow that poured into Yang Kai's body was cold and cold, as if it was going to freeze everything.

The airflow that poured into Yang Kai's body now was a little different from the feeling at that time, although these aircurrents were still cold, they didn't have the feeling of freezing everything.

"Demon core, can you even light up the words on the golden book in your mind?" Yang Kai was overjoyed, he had always been very curious about the golden book in his mind.

The sandalwood box was directly discarded by Yang Kai, and the demon core had already been held by Yang Kai.

In such a situation, the air flow that poured into Yang Kai's body was more efficient, and the thumb-sized demon core was rapidly becoming smaller at a speed visible to the naked eye, that is, in the blink of an eye, the entire demon core had completely disappeared and was swallowed up by Yang Kai.

"This ...... Refining the demon core so quickly......" Granny Long hadn't left yet, at this moment her eyes were wide open, and she looked at the scene in front of her in shock, and her eyes were almost falling out in horror.

The demon core is a good thing, of course Granny Long knows about it, but as far as she knows, those big people in the Chixia Sect, even if they have the help of secret methods, if they want to completely refine a demon core, it will take at least ten days and half a month's effort, the demon core is in her own hands, but Granny Long has tried her best, and she has been tossing for several years, but she has never been able to shake this demon core for half a point.

Granny Long originally wanted to take on more tasks and get more contribution points, so that she could exchange for the special secret method of refining the demon core in the sect, but now the demon core was forcibly taken away by Yang Kai, but what did Granny Long see? Yang Kai refining that demon core was just a few blinks of an eye.

What does this situation mean? Granny Long didn't know, she only knew that what Yang Kai could do in front of her, those big people in the Chixia Sect would definitely not be able to do.

"No wonder my natal poisonous insect drank fire before, and was crushed by Mr. Yang with one foot, Mr. Yang's strength, how can a little person like me guess at will?"

Granny Long's thoughts, Yang Kai didn't know, the demon core in his hand had disappeared cleanly, and Yang Kai's attention was mostly attracted by the golden book in his mind.

Before this, the golden book had to be on the cover, just two words of six desires plus one and a half horizontals, but at this moment, the words on the golden book have become four, and the six desires seal the sky.

"What a domineering name, could it be that this golden book, what kind of peerless secret book?" This thought suddenly appeared in Yang Kai's heart, and his face was already full of heat.
