Ling Feng eventually left, and it was something unavoidable. However, for Ling Feng, the good news was that he felt more reassured about matters behind him. Whether it was the Angel World or the Abyss Realm, whether it was the Bright Saintess or the Witch, in Ling Feng’s view, they were all trustworthy.

Even if he were to die on the Path of Immortality, he could be at ease. The only thing he regretted was possibly not being able to see his beloved ones, feeling sorry towards them.

But there was no choice; Ling Feng now had less than a year left, so he had to seize the time to strive for that last glimmer of hope for himself and for those lovers hoping for his return.

At this moment, in another space, the originally secluded Mad Doctor slowly opened his eyes: "You’re here?"

"You don’t seem surprised by my arrival!" A man appeared in front of the Mad Doctor, speaking lightly.

"I had long guessed that Lord Demon King would come to find me, but I didn’t expect it to be so soon." The Mad Doctor looked at the Demon King appearing before him and said lightly: "It seems that the state of the Demon King isn’t good; is the Abyss Realm on the brink of extreme instability?"

"That’s none of your concern!" the Demon King said, looking at the Mad Doctor: "I came to find you this time not for a reunion. I’m here for serious matters!"

"You’re here because of Ling Feng, aren’t you?" The Mad Doctor looked at the Demon King and smiled slightly: "I suppose the Witch couldn’t have kept what happened before a secret from you."

The Demon King said lightly: "Since you know I’m here because of Ling Feng, I won’t beat around the bush. I hope you can quickly distance yourself from Ling Feng and Earth. This Chaos Universe is immensely vast; as long as you leave them, they can’t possibly find you!"

"Oh? You want me to flee without a fight?" The Mad Doctor laughed heartily: "The key is, I never intentionally sought trouble with Ling Feng. On the contrary, I quite admire him. I even wanted to cultivate him into the strongest being in this world, but unfortunately, he remained distracted by so-called worldly ties, which left me disappointed."

The Demon King nodded: "I know you bear no personal grudge against Ling Feng; everything you do is for your ideals and beliefs. However, although Ling Feng is outstanding, he’s not the most exceptional existence in this Chaos Universe. I think you should set your sights on more planes to search for more exceptional talents to inherit your ideals and ambitions, don’t you think?"

The Mad Doctor smiled slightly: "Demon King, do you know how many planes I’ve searched through?"

With that, the Mad Doctor extended five fingers and said: "At least five thousand. I’ve incarnated in thousands, searching for the possibility to realize my ideals in thousands of planes, and Earth is just a trivial one!"

"Ling Feng wasn’t even considered a successful test subject before, and I didn’t take him seriously. At that time, he was merely a discardable pawn to me!"

"But what I never expected was that this person, whom I regarded as a discardable pawn, endured the torment brought by the Gene Potion, led the rebels of the Divine Gate, and successfully overturned my Divine Gate!"

"It was precisely at that moment that I truly started to take him seriously. I observed in secret and discovered that as he grew, once he left Earth and entered the alternate dimension of the Chaos Universe, his growth rate even shocked me!"

The Mad Doctor’s eyes held a trace of madness: "So, can you imagine how I feel? It’s as if I’ve searched high and low, only to find it effortlessly. I feel I’ve found the best test subject and realized the possibility of my ideals. Do you think I’d easily let go?"

"But do you think Ling Feng will follow your manipulation?" the Demon King said in a deep voice.

The Mad Doctor smiled slightly: "Of course... he will! Ling Feng doesn’t lack strategy, patience, opportunity, or insight, but he lacks a heart that is cold and ruthless. As long as I control his Achilles’ heel, he will obediently follow my orders!"

"His family, his lovers, his friends are his greatest weaknesses! So, at first, I didn’t have much faith in this species called humans because they have too many weaknesses. But now it seems that what drives Ling Feng forward is precisely these human weaknesses!"

"So, as long as I control Ling Feng’s weaknesses, he will move in the direction I want, and I have every hope of realizing my ideals!" The Mad Doctor’s eyes were filled with endless madness.

The Demon King shook his head; he initially wanted to persuade the Mad Doctor, but now it seems he truly is a Mad Doctor, a complete madman.

"In that case, I can only stop you!" The Demon King said, looking at the Mad Doctor, lightly: "Although you are now the Artifact Spirit of the Tooth of Greed, the Tooth of Greed is severely damaged right now, and you are not my opponent. If you insist on going your own way, even if it means my annihilation, I will make sure you are completely destroyed!"

The Mad Doctor frowned: "Demon King, as the Demon King of the Abyss Realm, to go to such lengths for an Earthling, I think you’re the one who’s crazy!"

"I’ve done too much for the Abyss Realm before; at the end of it all, I want to do something for myself, for my children!" The Demon King said lightly: "After all, Ling Feng is also my son-in-law, the man my foolish daughter loves deeply."

After speaking, the Demon King’s aura changed, his gaze burning as he looked at the Mad Doctor: "I originally wanted to persuade you, but now, do you truly want to be my enemy?"

The Mad Doctor’s eyes flashed with a trace of madness: "Haha, just as well, my strength has improved since before, and I want to test how powerful an Immortal Realm strongman truly is. Moreover... consuming you, my body will recover further, why wouldn’t I?"

"Alright, then I’m also curious about how powerful the Chaos Supreme Treasure truly is!" The Demon King took a deep breath, waved his hands, and the sky and earth changed color. Behind him appeared a massive Chaos Array Diagram.

The Mad Doctor also laughed heartily, and behind him appeared a colossal shadow, the true form of the Tooth of Greed.

With a loud boom, the two instantly vanished into mid-air. A powerful Space Storm spread out from the center of their conflict, and dozens of Plane Worlds around them felt this powerful fluctuation.

"There are super strongmen dueling!" In those Plane Worlds affected, the Guardians first sensed the power of this Space Storm, their faces horrified: "What’s happening, how can there be an Immortal Realm strongman dueling? This is quite dangerous now."
