At first, absorbing a single Soul Douluo's death aura would boost Evil Eye's age by 3,500+ years.
But as time went on—
The gain dropped to around 500 years.As it neared 100,000 years, it fell to less than 100 per kill.For Soul Sages, the increase was single digits.
It was only because the City of Slaughter was filled with twisted "Evil Soul Masters"
that so many high-level soul masters were concentrated here.
If this had been the outside world,
Evil Eye would have had no choice but to rely on the system to evolve.
But now—
It had finally reached 100,000 years!
Its soul bone skill remained the same,
but its effectiveness skyrocketed.
Beyond just extending its duration to 10 minutes,
it gained a new passive ability—
Tang Lan could pre-configure his status,
so that when it dropped below a certain threshold,
he would automatically rewind to a moment up to 10 minutes earlier!
For example—
If he set it to activate upon death,
then even if he didn't manually use the ability,
the moment he died, he would be restored to one minute before his death.
He could even configure it for—
Total exhaustion of spiritual power.Total exhaustion of soul power.Localized rewinds!
For example—
If he used his Blue Silver Emperor Right Leg Bone's Blood Escape technique,
draining all its stored life energy,
he could use Evil Eye's skill to rewind only the leg bone
without resetting his entire body's position.
"Damn, a 100,000-year soul bone really is broken as hell!"
Tang Lan was thrilled.
He left with Tang Hao,
ready to hunt down more "opponents" for tomorrow's Hell Slaughter Arena matches.
But the moment they stepped outside—
A bewitching woman greeted them with a radiant smile.
"Slaughter God, and you—9527."
"My master, the Slaughter King, invites you both."
Tang Lan remained calm.
The referee's behavior earlier made it clear this was coming.
Tang Hao casually responded—
"Lead the way."
Even without soul skills,
he was confident he could leave in one piece.
And as for Tang Lan?
That little monster was probably stronger than him—what was there to worry about?
Seeing them leave,
Tang San quickly stepped forward—
"Wait, bro, dad—can I come too?"
He didn't care about the Slaughter King.
He just felt safer staying with family.
Tang Lan didn't answer.
He simply looked at the Slaughter Messenger.
She apologetically shook her head.
"Sorry."
"The master only invited two. I don't have the authority to bring more."
"What?!" Tang San protested.
"Then go ask for permission! What's the big deal about bringing one more person?"
The Slaughter Messenger frowned.
This brat doesn't know when to quit…
She tried explaining it in a way he'd understand.
"The Slaughter King's status is supreme."
"You are just a Four-Ring Soul Sect."
"Just his aura alone might knock you unconscious."
Now **do you understand?
Tang San understood.
But his face turned black as coal.
She was looking down on him!
He turned to Tang Lan, about to argue—
"SMACK—!"
Tang Hao's signature slap sent Tang San crashing into the ground.
"You little brat, why are you so troublesome?!"
"The Slaughter King is the RULER of the City of Slaughter!"
"You think you can just see him whenever you want?!"
"If you don't wanna die, SIT DOWN AND SHUT UP!"
"Stop wasting my damn time!"
Then he turned to the Dark Demon Evil God Tiger—
"Little Tiger, keep an eye on him."
"If he tries to run, break all five of his limbs!"
The Dark Demon Evil God Tiger blinked.
It looked at Tang Hao.
Then at Tang Lan.
Then at Tang San.
…Are we sure they're blood-related?
(It didn't know Tang Lan could regenerate limbs.)
Even the Slaughter Messenger found this odd.
"…That level of favoritism is something else."
Tang Hao waved.
"Let's go."
"The sooner we meet him, the sooner we can get back to speedrunning the Hell Slaughter Arena."
The Slaughter Messenger: "…"
Only a Slaughter God would dare say something like that.
She didn't dare argue,
simply leading the way obediently.
As they walked,
Tang Lan turned back and yanked Tang San out of the ground.
He transferred some life energy into him.
"Little San, don't take it personally."
"Dad's words are harsh, but the truth is—"
"Right now, you're too weak for this place."
"Later tonight, I'll see if I can find a way"
"to get you into battles where you won't die."
"If that doesn't work, I'll just bring you along when I challenge the Hell Road."
Tang San silently nodded.
At this point, that was his only option.
Heading to the Slaughter King
After calming down Tang San,
Tang Lan caught up with Tang Hao and followed the Slaughter Messenger.
They arrived at the central palace.
The Slaughter Messenger bowed respectfully—
"The master is waiting inside the main hall."
"Please proceed on your own."
Tang Lan and Tang Hao strode inside without hesitation.
At the end of the hall,
the Slaughter King sat upon his throne.
His entire body was wrapped in a crimson cloak,
with a long blood-red robe underneath.
Only his pale face was exposed—
a middle-aged appearance with blood-red hair and eyes.
From a distance,
he looked less like a human and more like a gigantic blood-colored bat.
Tang Lan didn't bother with formalities.
He immediately scanned the Slaughter King with his spiritual power.
A violent, unstable aura surged back at him,
carrying a distinct scent of blood.
—That was the spiritual energy of the Blood-Red Nine-Headed Bat King.
As for his great-grandfather, Tang Chen…
Tang Lan couldn't sense him at all.
Based on Bo Saixi's teachings,
this meant Tang Chen's soul was dormant,
while the Blood-Red Nine-Headed Bat King had full control over his body.
Even his soul power reeked of blood,
proving that it belonged to the Bat King itself.
So That's Why He's So Weak…
No wonder—
In the original story,
despite his "invincible on land" reputation and the Slaughter Domain disabling soul skills,
he still struggled so much to kill Tang San.
It wasn't that Tang Chen was weak—
It was that the Bat King was just garbage.
"Hmm?"
The Slaughter King's eyes sharpened.
The killing intent around him suddenly condensed into a razor-sharp sword,
slashing toward Tang Lan's spiritual power!
But thanks to Danger Sense,
Tang Lan withdrew his spiritual probe just in time.
"Hmph!"
The Slaughter King scowled.
"You're just a brat—peeking around like that is rude!"
Tang Lan snorted.
"You invited me here, but I can't even take a look?"
"Fine, I'll leave."
His tone carried zero respect.
For someone who had been worshipped as a king for decades,
this disrespect was unbearable.
His anger solidified into a visible aura,
forming a coat of rolling blood-red flames around him.
It was intimidating—
but unfortunately,
Tang Lan wasn't normal.
And Tang Hao?
He was even less normal.
"Heh."
Tang Hao unleashed his full 98th-level Title Douluo pressure,
clashing directly against the Slaughter King's killing aura.
"It's been over a decade since our last fight."
"Wanna go for another round?"
The Slaughter King's expression darkened.
It brought back unpleasant memories.
The City of Slaughter was originally a trial ground
for the Asura God to choose an heir.
After the Bat King took over Tang Chen,
it had done everything possible to prevent the rise of new "Slaughter Gods."
If someone inherited the Asura God's power…
It would be game over for the Bat King.
And so—
