"Come with me, two of you."

After putting away the yuanshi, the woman led the two to the inside.

Walking slowly along the wide passage, after a while, the three of them came to the door of a small stone room.

"This is the key to this low-level retreat, and at the same time, it is also the key to activate the internal formations of the retreat room, they belong to you until you leave the retreat room, and no one has the right to enter it without your permission." As she spoke, the woman took out a palm-sized white jade plaque and handed it to Qin Yue.

"How do you use this thing?"

Taking the jade plate, Qin Yue glanced at it casually, there was an ancient character "nine" engraved on it, and he didn't know what material it was made of, but it was a trace of warmth in his hand, which was quite peculiar.

"There is a groove in the wall inside the retreat room, as long as you put the jade tablet inside, the door of the stone room will be closed, and the internal formation will be activated!" The woman explained briefly.

"yes, got it!" Qin Yue nodded lightly. Immediately, he took out a piece of high-grade yuan stone and threw it to the other party.

"Thank you, I wish you two success in your cultivation!" The woman smiled sweetly. She is just an ordinary receptionist, a high-grade yuan stone is a lot for her, and besides, she is just performing her job.

After the woman left, Qin Yue and the others stepped into the stone room.

I have to say that this low-level retreat room is really simple enough, and there is nothing but a futon in a central position. However, the material used to build the stone chamber is very unique, it is neither made of stone nor metal, it looks like wood like sunken wood, slippery to the touch, and a little cold.

There was a palm-sized groove in the center of the wall facing the door, and Qin Yue waved his hand casually, and the jade plaque in his palm turned into a bolt of lightning that was just embedded in it.

"Boom-"

As the jade plaque was embedded, the stone door at the door slowly closed, and the temperature in the room began to rise gradually, but the strange thing is that staying in the retreat room does not feel very hot, on the contrary, ** becomes warm, and the original slowly flowing true qi suddenly becomes lively, like a big river. Qin Yue knew that this should be the formation effect in the retreat room.

"The day has finally arrived!"

Turning around, Qin Yue looked at Qin Guiyi expressionlessly, a hint of amazement flashed in his dark eyes.

Although the two are destined to not coexist, it is undeniable that during this period of time, the two have gotten along quite well, and Qin Yue has encountered danger several times thanks to Qin Guiyi. How can people be ruthless? In the final analysis, Qin Yue still couldn't be ruthless like most Demon Dao martial artists.

"Truly...... I've been waiting for this day for a long time, and when I think that I can transform from a 'demon heart' to a deity right away, I can't help but be excited.......

"Really?" Qin Yue raised the corners of his eyebrows, and said coldly: "I think very well, but it's a pity that it's just a delusion!" ”

"Truly...... Whether it's delusional or not, we'll find out soon! Qin Guiyi smiled.

"Okay, then we'll see!" After finishing speaking, Qin Yue stopped talking nonsense, and with a move in his mind, he took back the puppet clone. In an instant, only Qin Yue was left in the retreat room.

"Whew~" Taking a deep breath and adjusting his mood, Qin Yue walked to the futon in the center of the retreat room and sat down. Then, with a flip of his right hand, a bright yellow pill appeared in the palm of his hand.

As the saying goes, if you want to do a good job, you must first sharpen your tools. The danger of refining the "Demon Heart" was extremely high, and Qin Yue had to be fully prepared before that. This is an elixir recommended to him by the guiding angel, called "Xuanming Heart Refining Pill", just by listening to this name, you know that its effect is to help refine the "Demon Heart".

And this "Xuanming Heart Refining Pill" is also Qin Yue's biggest reliance on refining the "Demon Heart", otherwise, if he only relies on his own strength, he really doesn't have much confidence that he can successfully refine the "Demon Heart".

"I only hope that this time I can refine the 'Demon Heart'."

After muttering a sentence silently, Qin Yue put the pill in his mouth, and immediately, he closed his eyes, hugged the yuan and returned to one, and gradually entered a state of concentration.

In the next moment, when Qin Yue opened his eyes, he appeared in a gray world. This is where his sea of knowledge, that is, where one's soul is. However, this sea of knowledge of his is unusually desolate.

The sky is gray, the earth is gray, all the qiē is gray, there is no life, no sound, nothing, and the whole world is shrouded in a layer of gray fog, which cannot be seen through or clearly.

Being in it, Qin Yue couldn't feel the slightest warmth, only endless depression, coldness, loneliness, and emptiness......

"How? Do you feel lonely, lonely, or uncomfortable? At this time, a familiar and cold voice sounded, and immediately after, a figure exactly like Qin Yue slowly walked out of the fog. It was Qin Guiyi who had just been "separated" not long ago, and he was also a "demon heart".

"Since the day I was born, I have been confined to this ghost place, no life, no killing, no blood, nothing, every day is spent in painful loneliness and loneliness, only in the last month or so, I finally tasted the taste of freedom, this feeling is good, really good, it's a pity, it's not really freedom, it's still limited by the deity, but it's okay......"

Speaking of this, Qin Guiyi showed a hideous smile: "Soon, I will be able to gain true freedom, and all of your deities, including the summoning space, will also belong to me, and I will ...... it."

"Don't be delusional, your only ending is to be refined by me!" Qin Yue said coldly.

"Truly...... I think, you don't seem to have figured out the situation yet, do you think you can really refine me by relying on that 'Xuanying Heart Refining Pill'? Qin Guiyi shook his head disdainfully: "You are too weak, so weak that even with the assistance of the elixir, you can't defeat me." ”

"Put away this set of yours, it's useless to me!" Qin Yue looked at Qin Guiyi indifferently, unmoved by Qin Guiyi's words. The process of refining the "Demon Heart" is a process of realizing the original heart, and the prerequisite for realizing the original heart is that there must be firm faith and determination, but if there is a trace of wavering, what awaits him is failure.

"Don't you believe it? Then I'll let you see how big the gap is between you and me, and ...... it" In the piercing laughter, Qin Gui's arms shook, and countless ink-like black lights suddenly burst out from his body, as if a dark cloud covered the top, and in an instant, most of the sea knowledge space was enveloped in it.

"I'm afraid you won't make it?"

Almost at the same time, a thick pillar of purple light Qin Yue also rose from the top of Qin Yue's head, and the shining brilliance quickly spread around Qin Yue as the center.

Soon, two different brilliances, one black and one purple, "collided" together.

When the purple light completely occupies the entire sea knowledge space, then it means that the "Demon Heart" has been successfully refined, on the contrary, if the purple light completely occupies the entire sea knowledge space, it means that the refining has failed. Regardless of success or failure, one side is bound to disappear, and this is a real "life and death" battle. Either you "die" or I "die".

In the next moment, at the moment when the black light and the purple light came into contact, a monstrous spiritual coercion suddenly rushed towards Qin Yue like a strong wind and waves, directly impacting the depths of his will, violently shaking his thoughts and thoughts, and there seemed to be a tendency to replace them, and at the same time, the purple light was also retreating in the "collision" with the black light.

"Not good!"

Qin Yue was suddenly horrified, he didn't expect Qin Guiyi's spiritual mind to be so terrifying, this was still unable to parry even if he swallowed the "Xuanming Refining Heart Pill", if he only relied on his own strength, wouldn't he be defeated by the other party in an instant? Not daring to slack off, Qin Yue exerted all his strength, frantically urging his spiritual thoughts, in a vain attempt to regain his disadvantage.

However, Rao was like this, and it only blocked the erosion of the black light, and the purple brilliance in the sea space was still slowly weakening with a degree that was visible to the naked eye. If this continues, it won't take more than a quarter of an hour, and the entire sea space will be occupied by black light.

"Truly...... I said, you are too weak, you are not my opponent at all, it is better to give up, you ...... the cold laughter hit Qin Yue's spiritual will like a wave, and he wanted to make his will collapse.

"Don't think!"

Although the shape is quite sinister, Qin Yue, who has comprehended the "unyielding" will of the ancient demon god, will definitely not succumb to anything.

"Why bother? You and I are one, you are me, I am you......"

"Don't you want to step into the pinnacle of martial arts? As long as you and I are integrated, this goal will be achieved in no time......"

"Come on, don't resist, let's completely merge......"

……

Time passed slowly, and Qin Guiyi's cold and strange voice was accompanied by terrifying spiritual coercion again and again to impact Qin Yue's spiritual will, wanting to break it and shatter it.

However, Qin Yue was still unmoved, just gritted his teeth and silently urged his spiritual thoughts, trying to resist the step-by-step expansion of the black light. Under the erosion and coercion of black light, his spiritual will was infinitely oppressed and tortured, coupled with the burden of losing his body's vitality, which made him almost collapse. It is only by an unyielding will that he is trying to persevere.

Soon, most of the Zhihai space had been occupied by black light, and the entire Zhihai space was basically shrouded in pitch black, except for the faint purple light that still shone within a radius of a few zhang around Qin Yue. He was like the hardest diamond in the forest, and no matter how hard the tree tried, it could not be opened, but could only grow around the sides.

To take a step back is to "die", at this time, no one can help him, only himself can be relied on......
