Among the many notes, only one wrote about the source of the demonic energy.

It is said that as early as the ancient times, there was chaos between heaven and earth. There was nothing in the world, and as far as the eye could see, there were gray air masses all around, and nothing could be seen clearly, and these fog masses were moving every moment, like bursts of dust storms.

At that time, there were no living beings. Until a beam of light splits these gray air masses, the mist rotates rapidly, forming a hurricane, and after tens of thousands of years of refining in the light, the gray mist is separated into two kinds of qi, one is the dark and black demonic qi, and the other is the aura that is gold on the periphery and white on the inside. These two breaths collided with each other and spread around, and since then, the world has come to life. Everything is revived, and life is everywhere.

Creatures with demonic energy have fierce, domineering, and direct personalities, and they grab and fight for what they want to get, while creatures with spiritual energy have soft, calm, and rational personalities, and they take harmony as the way. Slowly, the creatures with aura in the world call themselves gods, and the creatures with demonic energy call themselves demons.

The source of the demonic qi is located at the bottom of Liuhe Mountain, and the source of spiritual energy is located at the bottom of Luhe Spring. But almost no one knew about it, until the Protoss found the source of demonic energy, and they weakened it with the magic weapons made by the Nine Mountains Clan, so as to weaken the strength of the Demon Clan, and suppressed them in the final battle. However, at that time, the demons didn't know about the source, and they even thought that their own clan's strength was not enough.

As for the inner demons, in fact, they appeared as early as ancient times, except for the records of the Jiushan clan using their own writing, there is no record in other ancient books. The heart demon is a special body that can be born only by people who have aura, and the demon qi and the aura are of the same origin, but if the person who has the aura is uncertain, the desire and paranoia will make the aura deteriorate, and it can attract the demon qi to form the special body of the heart demon.

The inner demon can only be destroyed through the magic circle of the Nine Mountains Clan. And the source of demonic qi can only be weakened with a magic circle, and if the demonic qi does not disappear, there will be other demons born.

Unless the person who has the aura cultivates the demonic qi and the aura through the northern cold qi, so that the spiritual veins can adapt to the two powers, then he will get the strongest power in the world, and he can even use this power to fuse the source of demonic qi and the source of spiritual energy, so that the two opposing breaths in the world will be refreshed.

It is born from the same root, but it must be separated, if it can be fused, the world will be peaceful.

……

That's the general idea of what is recorded in the dense notes

"Cold ......" Mu Fanxi raised his right hand and looked at his palm thoughtfully.

"It seems that there is no other way but the magic circle." Cangyuan Baiyu interrupted her thoughts.

If you use a circle, it means that there will be a sacrifice and there will be a sacrifice.

"Master, I won't let you die." Mu Fanxi looked at him with a firm look in his eyes.

The more she tried to protect him, the more he regretted what he had done to her when he suppressed his desires.

After all, when he used his spiritual power to suppress his desires, he was bent on killing demons and even letting his beloved little apprentice die.

Now looking at her eyes that were determined not to allow herself to be sacrificed, he regretted it to the extreme.

Cangyuan Baiyu already had a plan in his heart, but he still followed Mu Fanxi's wishes: "Then what do you want to do?" ”

She pondered for a moment, trying to find the flaw in the circle: "I'm thinking, if the circle needs a so-called 'sacrifice' as an intermediary to get rid of the demons, then why does it have to be human?" Maybe we can find something like a spirit bead, seal the demon in it, and attach it to a puppet full of aura, maybe it will be possible? ”

Mu Fanxi's thought was still too simple, but Cangyuan Baiyu didn't point out the inappropriateness: "Well, you can try." Then we will work hard to find such an object. Benjun concentrated on studying the magic and tried his best to completely suppress the demons in his state of mind. ”

"Good! Leave it to me! Mu Fanxi breathed a sigh of relief, "By the way, Master, the cold qi mentioned in this note, I think maybe I and Xuefei Shangshen can try it." ”

"You want to fuse them?"

"Hmmm! If it is true that as this note says, the aura and the demonic qi have the same root and origin, then why not merge the complementary ones into one? If all the living beings in the world cultivated the same kind of vitality, then maybe there would be no more war between the two races of immortals and demons. Wouldn't it be nice that the clans wouldn't worry about demonic energy invading their minds? ”

"The method of cultivating with cold qi is not recorded above, if you want to try, you can ask Xue Fei Shangshen."

Mu Fanxi nodded: "I'll go to the Prayer Mountain." ”

At first, when Yun Shu discovered the source of demonic energy, she couldn't believe it.

She only remembered hearing her father talk about the source of demonic energy when she was very young, but when she saw countless demonic qi slowly rotating around a point, she boldly guessed that it was the source of demonic energy.

And the demonic qi was able to find Yun Shu purely because she had a wisp of demonic aura in her heart.

The moment she saw the source, she had a feeling of being tempted and attracted by the power of demonic energy, and there seemed to be a voice in her heart telling her that as long as she could absorb these demonic qi and refine these demonic qi, then her great revenge would be avenged, and she would become an unrivaled immortal family in the world.

For a moment, she raised her hand as if she had lost her mind to touch the richest source, but she quickly came to her senses and withdrew her hand.

Seeing that the infinite power was close at hand, she made a bold decision. If she was caught by Cangyuan Baiyu and Mu Fanxi and experienced the tragic situation that life was worse than death, it was better to fight to the death, maybe she could really refine these demonic qi and take it for herself.

At that moment, she walked out of the cave and searched for an herb in the mountains.

She wanted to use an ancient forbidden technique to refine demonic energy, but only if she took an herb called Dream Netherworld to keep herself in a state of separation between life and death.

It took her three days to find her, and in the middle of it, she encountered a number of untransformed jackals, tigers and leopards who tried to devour her, but she escaped death, she returned to the cave and swallowed the herbs.

Between life and death, she sat cross-legged, opened the spiritual veins of her body, sealed the forbidden technique, and scattered the spiritual energy in exchange for the same demonic energy into her body.

After a night, she fell into a spell.

Yun Shu succeeded halfway, and her life was temporarily saved, but she couldn't fully control the power of demonic energy, and she had to cultivate to the extreme day and night.

With her belief in revenge, she practiced urgently in the cave day and night, and the demonic energy around her gradually stabilized. Three days later, that is, the day Mu Fanxi and Cangyuan Baiyu went to Jiushan, she finally practiced.

Yun Shu can freely grasp the powerful demonic qi of the source, but her lifespan is only three months, and if she wants to prolong her life, she must absorb and snatch the lifespan of other demons.

She stepped out of the cave, and her soft apricot eyes were already stained with blood. She used her demonic energy to create a long black dress for herself, repaired the scars on her face, and she looked at the sky, but flew to the Demon Cave Ridge.

The Demon Lord felt a different aura pouring into the Demon Clan in the tower.

He teleported to the top of the tower and looked down at the west side of the Demon Cave Ridge, only to see a familiar figure moving slowly.

The demonic aura around her was something he had never seen before, a black mist wrapped in purple fluorescents.

"Yun Shu?" He recognized her.

The rest of the demon clan blocked Yun Shu's way, holding weapons in their hands, and they were still mocking the woman in front of them when they didn't know that death was coming.

"New here, huh? What is the ontology? looks pretty well, do you want to go back with Uncle Ben to be Mrs. Zhai? ”

"What are you doing, how many concubines are there? Follow me! Guaranteed to be big! ”

"In my opinion, it's better to dedicate it to the Demon Lord, after Gu Shuang is gone, there will be no woman by his side!"

Yun Shu raised his eyes and glanced around, like looking at a group of ants.

She didn't say a word, she didn't move, only to see the demonic qi around her form a hand and quickly rushed towards their necks, the moment they grabbed it, their green muscles burst out, and for a while only the whites of their eyes remained, and they fell to the ground one after another, and then turned into dry corpses.

Seeing this, the Demon Lord jumped down and stood in the middle of the group of corpses.

"When did Fairy Yunshu become enchanted?"

She didn't even look at him, straightened her sleeves unhurriedly, and slowly spit out three words: "I want you to take care of it." ”

"Where did your demonic energy come from?"

Yun Shu raised his eyes and met his yin owl eyes: "You guess." ”

"Interesting, that deity will peel off a layer of your skin and see what is so special about the demonic energy in this spiritual vein."

-

Prayer Mountain.

Mu Fanxi came to the residence of the god of Xuefei.

"God." She saluted.

Seeing that Mu Fanxi was fine, although Xue Fei was calm on the surface, her heart was happy.

Xingyuan Xianjun had already seen her careful thoughts, and hurriedly assisted the mother and daughter: "Fan Xi, you haven't heard any news in the past few days, but Xue Fei is worried, and you have to go to the door every day." ”

"You don't speak, no one treats you as a dumb person." Xue Fei glanced at him, and the cold chill in her eyes made Xingyuan shiver.

Mu Fanxi naturally knew what Xingyuan meant by this, and she was also happy in her heart. It's just that her mother is now a god, and she also wants to find a different way to get along with her, maybe slowly she will be able to open her heart, and Mu Fanxi will be able to return to her original appearance with her.

"Why did you come to me today, did you encounter something?" Xue Fei asked.

Mu Fanxi nodded: "Master and I found a few pages of the Jiushan clan's notes, and we wanted to see if there was anything related to demon slayer, but there was only one page about the source of demonic energy. ”

She recounted what she had seen to Xue Fei Shangshen, and continued to add: "Since the demonic qi and the spiritual qi are originally one, I want to use the cold qi to merge them again, if it is really as the handbook said, it will not be a good thing to refresh the cultivation qi in the world." But it only says that you can use cold air, but it doesn't tell you how to use it, so I want to ask if God knows about it. ”

Xue Fei thought for a moment, got up and walked into the back room.

A moment later, she came out with an ancient book.

"I don't know how to do it. There are all the cultivation techniques of cold qi in this, plus the Shuo cold technique I gave you, maybe you can take it to study and study, maybe you can find something. ”
