PS: sorry, I''ve caught a bad cold recently. I''ve been delayed for a few days.


    The heart demon hall is divided into nine heaven, one more dangerous than the other.


    The nine worlds are all evolved by the nine orifices of the dark ancestors. The space is solid and there is no obvious boundary. If you want to go to the upper world, you must first find weak space nodes before you can jump in space.


    "The dark nether ancestor has been silent for a long time. If the demon heart recovers this time, it will be a catastrophe to the whole practice world."


    "I didn''t expect that the elder still has a heart of compassion."


    "Hey, you''re ridiculous. I''ve been killing people all my life. I''ve done all kinds of bad things. My heart is darker than anyone. I don''t feel sorry for heaven and people. The reason why I say this is just that I''m worried about the birth of the dark ancestor, which will make my way empty."


    After flying all the way, after about a column of incense, Taoist Ku stopped and said, "well, this is it!"


    Then he tore his hands forward, and the void in front of him suddenly twisted and deformed, and then cracked with a huge hole.


    When Yang Xuan saw this, he couldn''t help admiring it.


    The space in the heart demon hall is almost indestructible. Even if he found a space node with his cultivation, he could never break it by force, but Taoist Ku tore the space with his bare hands.


    "Come on, let''s go to the second day."


    Taoist Ku waved his hand, then took Yang Xuan, stepped into the space in front of him, and came to another strange space.


    Here, different from the first heaven, heaven and earth have evolved. Looking up, the sky is gray, and there is no vegetation on the earth. The whole heaven and earth is like an isolated and desolate world, which is filled with countless demonic desires.


    The desire of demons is everywhere. It can easily confuse people''s hearts and make people fall into the devil''s way. Yang Xuan may not be able to resist it unless Taoist Ku quickly launches the dead area.


    He entered the Tao with emotion and demonstrated the Tao. He also bears the blood of the demon family. There are many demons in his own heart. Once he is invaded by the desire of the external demons, he will definitely let his demons explode and suffer. The worst result is the loss of his mind and become a puppet without emotion.


    "Good luck. There seems to be a treasure ahead."


    The dry Taoist suddenly said.


    "Treasure?"


    Yang Xuan was surprised when he heard the speech. "What treasure is it and how did you find it?"


    "Of course, I can see it with my eyes. My eyes can see through the vain Nirvana and sense any breath fluctuation."


    Taoist Ku smiled and said, "let''s go and collect the treasure first. It should be a collection of the dark nether ancestor, and what can be favored by the dark nether ancestor is definitely a great treasure."


    "Good!"


    Yang Xuan naturally had no objection to this. Next, the two didn''t stop at all and flew in one direction at full speed. At the time of such a tea, there was a bloody thick fog in the distance.


    The bloody thick fog, I don''t know why it was born, shrouded in an area of unknown tens of thousands of miles, and my mind can''t penetrate into it, and I don''t know if there is any danger. However, Taoist Ku ignored it and rolled up Yang Xuan directly into it and flew to the depths of the bloody thick fog.


    In the blood fog, there was no desire for demons, but it contained a surge of blood, which made Yang Xuan only feel that he had come to a killing blood field.


    "The blood mist is very terrible. It can easily kill people. Follow me, boy. Don''t walk around."


    Taoist Kuo told him that the blood color is thick and the fog is thick and can''t melt. It can easily turn people into pus. This is that he has high cultivation and body protection in the field of death. Otherwise, he doesn''t dare to come here to try his own danger.


    "Here we are!"


    Soon, Taoist Ku put down Yang Xuan and came to the innermost part of the blood fog, where the blood fog became thicker and thicker, and all kinds of terrible killing sounds could be heard from time to time in the thick fog.


    The killing sound, rolling like thunder, seems to come from an ancient battlefield and will never disperse.


    "What is that?"


    At this time, Yang Xuan saw something and fixed his eyes on a bloody long knife not far away.


    The bloody long knife, several feet long, was ferocious and sharp. It was so suspended in the void. It was full of frightening blood light and frightening power.


    Obviously, it''s a big killing weapon. In terms of lethality, it''s not much worse than Pangu axe, but the more powerful the treasure is, the more difficult it is to sacrifice and refine.


    Forced sacrifice and refining may also be life-threatening. After all, no one knows whether there is a sword spirit in this bloody long sword. If there is a sword spirit, this spirit is definitely a vicious Lord and will not recognize the Lord easily.


    "If I''m right, this should be the legendary blood sacrifice magic knife."


    Taoist Ku narrowed his eyes.


    "Blood sacrifice magic knife?" Yang Xuanwen didn''t hear of it.


    "It is said that in a distant era, there was a blood ancestor who became famous earlier than the fatalistic Lord. His famous weapon is the blood sacrifice magic knife."


    "I see. Is this blood ancestor still alive?"


    "This is not clear. Some people say that the blood ancestor has long died, others say that the blood ancestor just fell into a long sleep, and the emergence of the blood sacrifice magic knife just confirms this speculation that the blood ancestor is not dead and is accumulating strength through this magic knife."


    "Accumulate strength?"


    "You don''t know, this blood devil sacrificing knife is very important. This knife is a treasure of the blood way, which was refined by the blood ancestor himself. As long as this knife is still there, the blood ancestor can collect blood energy through this knife wherever he is. Unfortunately, the recovery plan of the blood ancestor has to make a wedding dress for the dark ghost family after all."


    "Elder, did you say that the dark ghost ancestor kept the blood sacrifice magic knife to make the blood ancestor''s idea?"


    "No mistake. The blood ancestor used blood to prove the Tao and almost had an immortal body. If the dark ghost ancestor wanted to prove the Tao with heart demons, he needed to find a strong body like the blood ancestor."


    "In that case, what should we do now?"


    "What else can you do? Naturally, take the magic knife."


    "Is that ok?"


    "There''s nothing wrong. You''ll go and get the knife now. Remember, don''t try to sacrifice and refine the knife. With your current cultivation, the moment you sacrifice and refine the knife will become the sacrifice of the knife and be drained of your blood in an instant."


    "Is it too dangerous!"


    Yang Xuan took a breath and didn''t hurry for a moment. It''s true that the blood sacrifice magic knife is very strong, but no matter how strong the magic knife is, it must have a place to play.


    "It''s always useful to keep it. Just take it away."


    Taoist Ku is not angry.


    "I hope you don''t hurt me."


    Yang Xuan smiled bitterly and could only go forward with a hard head and grabbed the blood sacrifice magic knife. As the blood sacrifice magic knife fell into his hands, he immediately felt a mysterious message through the magic knife in his hand.


    It was an ancient and boundless, like a message from a distant place, with a bewitching evil thought. If Yang Xuan''s heart was not firm, he would lose control of his body on the spot.
