Kaka couldn't be killed, but he wasn't immune to pain.
The reason he was unkillable was that he had suffered many beatings in his life and feared pain, thus transforming into an unkillable monster when converted into a memetic entity.
Unfortunately, his skill points were spent poorly.
Wan Lei charged forward again, his fists flying towards the Illusory Heart Demon Emperor, with Kaka close behind.
Despite being a battle between Demon Emperors, all three combatants swung their fists, using the simplest of attacks against each other.
They fought with their highest combat power using the most primitive methods.
Kaka was unkillable, but his attack power was weak. If the Illusory Heart Demon Emperor went all out, he would be repelled, and he could not inflict any damage on her; he was purely a meat shield.
Wan Lei's defense was not particularly strong. Although he could deal damage to the Illusory Heart Demon Emperor, with each direct clash, he sustained more severe injuries than she did.
If he and Kaka could merge into one, then with immortality and formidable attack power, he could wear down the Illusory Heart Demon Emperor to death.
However, in many situations, one plus one did not equal two, and two individuals combined could not achieve the effectiveness of a single Saint-level expert.
After being sent flying several times, Wan Lei finally remembered that he had a weapon.
Despite losing his reason, he was still an intelligent being. Even with a desire to destroy the world, he was not a mindless automaton. Faced with a disadvantage, he would instinctively seek a solution.
He drew his Source Thunder Hammer and charged at the Illusory Heart Demon Emperor.
The Illusory Heart Demon Emperor had no weapon. She never imagined that she, the strongest illusion master of the Demon Race, would one day resort to using a blade to fight.
It was a sacrilege to illusions.
By this point, she was truly enraged. Two beings like ants dared to fight her on equal footing; this was the shame of her life.
She wished she could smash these two fellows into a pulp with her bare fists.
Facing the charging Source Thunder Hammer, the Illusory Heart Demon Emperor roared and punched it, even though her fist was already bloody and mangled.
Wan Lei was sent flying again, and the Source Thunder Hammer in his hand let out a pained cry.
Gouzi leaped out of the hammer, glanced at his opponent, and was so terrified that he immediately cursed,
"Holy crap, Xiao Lei Zi, what are you doing? You're fighting a Demon Emperor? You're actually using me to smash a Demon Emperor? How could you even think of that? What makes you think I can contend with a Demon Emperor? You think highly of me, don't you…
Huh? What's wrong with you?"
As Gouzi spoke, he also noticed that Wan Lei's condition was not right. There was no reason for Wan Lei to be able to clash head-on with a Demon Emperor.
He was telepathically linked with Wan Lei, but when his divine sense entered Wan Lei's mind, it was instantly crushed by the boundless savagery.
"Ah!! What is this, my head hurts so much!"
Gouzi screamed and retreated back into the Source Thunder Hammer.
Wan Lei could no longer concern himself with Gouzi. If there were no opponents, Wan Lei might have grabbed Gouzi and crushed him to death.
He picked up the Source Thunder Hammer and charged at the Illusory Heart Demon Emperor again.
Even though his injuries worsened with each blow, even though his body was riddled with holes and on the verge of collapse, even though his mind had completely shut down and was utterly exhausted, under the control of the Demonic Ring, he still desperately wanted to kill the enemy before him.
It wasn't that he was borrowing the power of the Demonic Ring; the Demonic Ring was controlling him.
With the addition of his weapon, Wan Lei's combat power saw a slight increase, and the hammer could also offset some of the enemy's damage for him.
Even though Gouzi inside was screaming in pain.
The battle continued. The conflict between the Positional Plane and the Demon Race below had long since stopped. Everyone looked up at the sky, watching the unbelievable battle.
"You little thief!!!"
The Illusory Heart Demon Emperor was pushed to her limits. Her fury surged, and her loss of reason was comparable to Wan Lei's.
"I've changed my mind. I won't kill you. I will turn you into my slaves, tormenting you day and night. I will peel the flesh and blood from your bodies, piece by piece, and then feed it back to you!"
The Illusory Heart Demon Emperor roared ferociously, her domain of illusions expanding and instantly engulfing both Wan Lei and Kaka.
The strongest illusion of the Negative Plane, under the Illusory Heart Demon Emperor's control, swept over the two.
A moment later…
"Huh?"
The Illusory Heart Demon Emperor was surprised to find that the two before her were completely unaffected by her illusions, still launching ferocious assaults at her.
What was going on?
In her surprise, the Illusory Heart Demon Emperor first released her divine sense, entering Kaka's sea of consciousness.
She intended to personally control the illusions to deal with her enemies.
However, upon entering Kaka's mind, she discovered that there wasn't even a trace of mental energy within. She couldn't control, influence, or even destroy anything.
With no mental energy, what could she manipulate?
Kaka was a memetic entity, a member of the Weiyang race, possessing no mental energy. He had no cultivation or energy, only his physical body and the core memetic entity within.
No one had ever been unaffected by the Illusory Heart Demon Emperor's illusions, not even the Three Suns Saint; they merely had stronger resistance.
Unwilling to accept this, the Illusory Heart Demon Emperor turned her gaze to Wan Lei and infiltrated his sea of consciousness with her divine sense, infused with illusions.
In an instant, upon seeing the boundless savagery and bloodlust, the Illusory Heart Demon Emperor felt her wisp of divine sense being directly annihilated, followed by an excruciating pain in her own mental energy.
"Ah!!!"
The Illusory Heart Demon Emperor cried out in agony. She, who always enjoyed toying with her enemies' mental energy, now found her own mental energy severely wounded.
That pain of annihilation, that chaotic savagery, made her doubt if she was about to become an imbecile.
Seizing the opportunity, Wan Lei roared and smashed his hammer into the Illusory Heart Demon Emperor's forehead. Instantly, her forehead split open, her skull caved in, and green blood gushed downwards.
Even by the aesthetic standards of the Positional Plane, she was stunningly beautiful, but now she appeared monstrous, like a vengeful spirit.
"You scoundrel!"
The Illusory Heart Demon Emperor had gone mad. She felt that the unbelievable things she had encountered today outnumbered all the encounters in her entire life.
She was a Demon Emperor, capable of easily crushing these ants, but unexpectedly, two cockroaches that couldn't be killed had appeared.
She employed her most prized illusions, only to encounter two earth-shattering bugs.
One was a memetic entity, without a soul or mental energy.
The other, completely occupied by the Demonic Ring, had all its mental energy usurped. When the Illusory Heart Demon Emperor's external mental energy invaded Wan Lei's sea of consciousness, it directly collided with the Demonic Ring's power.
Wan Lei's mental ocean now belonged to the brutal, murderous power of the Demonic Ring. How could such a noble entity tolerate the invasion of a mere ant's mental energy?
Heh, you want to go head-to-head with the terrifying mental power of the Supreme Demonic Ring?
You're seeking death, overestimating yourself!
