Looking at the enormous Yin-Yang array beneath his feet, Jiang Mu called out loudly, "Brother Wu, is that you?"

The aged voice rang out again: "Of course it's me, but I'm the reborn me."

“Brother Wu, you have always been the role model we have been looking up to. Why would you want to learn those demonic techniques?”

"Hmph, Jiang Mu, I am no longer that Wu Ji. I have dedicated my life to the Ziwei Sect. I owe the Ziwei Sect nothing."

"Brother Wu, since you want to prolong your life to cultivate demonic arts, you can't scheme to start a war between the human and demon races. Do you know that the Ziwei Sect was almost destroyed because of you?"

“I’ve said I don’t owe the Ziwei Sect anything. You don’t need to say so much to me. For the sake of our past as fellow disciples, tell me your last words, and I will help you complete them after I achieve enlightenment and break apart.”

Jiang Mu shook his head and smiled bitterly, "I have no last words. I'm content to die at Brother Wu's hands."

"That's good. Does this formation look familiar to you?"

“Brother Wu, this is a secret technique passed down only by my Ziwei Sect, the ancient Yin-Yang Two Elements Formation. Once you activate the formation, we will be obliterated by the Yin and Yang energies. It is several times more terrifying than the Heavenly Punishment Falling Immortal Formation jointly cast by our four sects!”

An aged voice echoed from all around: "It's good that you understand. I spent ten years preparing for this formation, gathering all the necessary materials to set it up, just so that it would be exposed one day and kept as a trump card. Now that I have you and Yadu, it's not in vain that I activated this formation."

“I know this formation is powerful. The first sentence in the formation’s inheritance is that if it is not broken, one will die. How could I not understand that we are doomed? Brother Wu, Jiang Mu has a wish. Can I see you one last time before I die, so that I will have no regrets?”

The aged voice did not sound again, as if it was considering something.

Jiang Mu couldn't see anyone, so even if he had a powerful weapon, it would be useless; at most, he could only protect himself.

Seeing that Wu Ji was no longer speaking, he pressed on, saying, "Brother Wu, back then you were the one who led me through the martial world, and you were the one who stood in front of me when danger came. You have always sheltered me from the wind and rain. After today, I'm afraid we will never see each other again. Can't you show yourself to me?"

The aged voice seemed moved by Jiang Mu's words, and voices around them rang out: "Jiang Mu, don't blame me for being ruthless. I changed from the day I started cultivating demonic arts. Now that you're dying by my hand, I can't bear it. Drink this demonic blood, and I'll let you out, okay?"

As he spoke, a crimson light appeared within the formation. When the light dissipated, a bowl of still-steaming blood appeared in front of Jiang Mu.

Jiang Mu dared not drink it! He didn't even want to touch it!

“Brother Wu, although I, Jiang Mu, cherish my life, I would never dance with demons. You underestimate your junior brother. You might as well just kill me with one stroke!”

Wu Ji had not expected Jiang Mu to be so fierce, and couldn't help but feel a little annoyed at his own descent into demonic possession.

Another burst of crimson light appeared within the formation, this time even brighter, and finally transformed into a human shape.

"Ah, Brother Wu, I never expected you to treat Jiang Mu's dying wish so carelessly. Fine, my Brother Wu is already dead. Quickly activate the formation. I, Jiang Mu, would rather die than be toyed with by you!"

Jiang Mu angrily pointed at the illusory figure constructed by magic in front of him and roared. As he spoke, he suddenly burst into tears. How tragic!

The fictional figure vanished, and the aged voice rang out again: "Alas, Junior Brother Jiang, it is my incompetence that I could not resist the temptation of the demonic path. I am not as great as you. Don't worry, I will take care of your family after you die."

Jiang Mu closed his eyes and sat down on the spot, seemingly in utter despair, waiting for death.

Ya Du understood that Jiang Mu's performance was over, a complete defeat. It was now his turn to take the stage. He knew that as long as he could force out Wu Ji's true form, Jiang Mu's immobilization talisman would be enough to reverse the situation.

"Hmph! Wu Ji, you have never been my match for thousands of years. You have always been my defeated opponent. I used to think you were a great man, but today it seems that I, Ya Du, was blind and overestimated you."

The aged voice changed its tone, saying, "Yadu, I admit that you are individually strong, but now I have not only mastered the Law of Metal, but also nearly perfected the Way of Yin and Yang. Even in a one-on-one fight, you are no match for me. Yet you still dare to bark here?"

"You're no good at fighting, but you're the best at bragging. I've been invincible for so many years, and I couldn't stand the loneliness, so I once sought you out for a duel. I didn't expect you to break the rules and invite two high-level cultivators to gang up on me, which is how we ended up fighting to a draw. What right do you have to talk to me here?"

"You should look at me with new eyes after just three days. My Yin-Yang Laws are now nearly perfect, and I am about to break through to the Dao. From now on, I will be able to fly freely in the sky and leap freely in the sea. I will be the number one person in the Qingxuan Continent. How could you possibly know what it will be like then?"

"Why say so much? Do you dare to fight me head-on?"

"Hmph, believe it or not, I've always been curious. You were all seriously injured before entering the palace, but now you're all full of energy. How did you manage that?"

Seeing that Wu Ji was not falling for the trick, Ya Du cursed inwardly, but calmly said on the surface, "You want to know? Why don't you search my soul? Isn't this a common tactic used by your demonic path? If you win, I'll know."

"Heh, I see now. You all want my true form to appear, you must have some kind of killer move! It's laughable, Jiang Mu already brought people to open my coffin, what feelings are we talking about now!"

Jiang Mu cursed Ya Du for being too obvious and having no talent for acting. He stopped Ya Du from continuing and said, "Wu Ji, you don't need to test us anymore. Our injuries have been healed entirely because of a magic pill. We don't have any killing moves against you. You should activate the formation quickly."

Sure enough, upon hearing the words "immortal pill," Wu Ji immediately asked, "Immortal pill? Junior Brother Jiang, do you think I'm a fool? I've lived this long and have never heard of any immortal pill."

Jiang Mu sighed, "Alas, I obtained that in a secret realm many years ago. After you faked your death, I was so heartbroken that I sealed one of the immortal pills in a hidden layer when building your coffin. This time, I was already seriously injured, and for the sake of the future of the Ziwei Sect, I had no choice but to open the coffin and take out the immortal pill."

As he spoke, he slashed with his right hand, and a pool of blood flowed from his wrist, but it disappeared in an instant, clearly taken away by Wu Ji.

"It really is! It really is celestial energy!"

"One of them? Junior Brother Jiang, are there any more of those elixirs?"

Jiang Mu closed his eyes and slowly said, "I did this only to prove that I had no choice but to open the coffin. As for suspecting Brother Wu and digging up the grave to examine the body, that is absolutely not true. I have a clear conscience, and I disdain to associate with your demonic path. Quickly activate the formation."

"Junior Brother Jiang, I was nearing the end of my lifespan when I accidentally obtained this demonic cultivation technique, which allows me to change my appearance and live another life. It is understandable, please forgive your elder brother!"

Who knows if Jiang Mu still has any elixirs? In any case, there's no doubt that there aren't any left in his coffin. If Jiang Mu doesn't say that he can only use soul-searching, then he can only use this method if Jiang Mu is alive. This makes him want to sound out Jiang Mu first.
