Chapter 676

The Grand Masters could not fathom it! What did they hope to gain? They were merely hindered by their mutual enmity, unable to communicate, so this mystery remained unsolved.

Now, Su Han understood the key to this mystery.

The Underworld had been corrupted by something called Darkness.

The Four Saints of Underworld legend had not died; they had merely been corrupted by Darkness.

Those corrupted by Darkness, though retaining their original appearance, had their souls reforged.

And they were filled with a desire to destroy everything outside the corrupted realm.

Not only did Earth's Grand Masters feel their world teetering on the brink of destruction, but they themselves sensed it.

The Beast Emperors of the Underworld likewise felt their own world on the verge of ruin.

The reason the Underworld furiously invaded the real world was because they sought to turn it into their backup base.

Thus, those... supreme Beast Emperors could place their outstanding descendants here.

If the invasion of Earth succeeded,

then one day, even if the Underworld fell, they would still have a chance of survival.

"Truly insane... the Underworld fights to the death to attack Earth! All just for their own survival."

Su Han felt a pang of emotion, yet a heaviness settled in his heart.

He had once believed himself invincible in the real world; even if the Underworld truly invaded, his strength alone could protect the world.

But now, Su Han realized he might have been wrong.

The Four Saints corrupted by Darkness, while still alive, had sensed something amiss and built tombs to bury themselves, entrusting their containment to the top Beast Emperors of each race.

Though under containment, the Four Saints' combat power grew stronger over time.

Recently, several anomalies occurred within the tombs of the Four Saints.

The fallen Saints nearly broke free, causing massive disturbances.

This was precisely why Earth's side knew of the tombs of the Four Saints.

Yet due to various reasons, Earth's side still lacked deep understanding of the tombs of the Four Saints.

They understood even less the truth of Darkness.

"These old Saints corrupted by Darkness— their combat power is probably no weaker than mine..."

Su Han's lips twitched twice as he pondered another question: "Should I find Yu Qiyu, Qi Mu Nanxiong, Aizen Sōsuke, Bai Hu Zi, and Hou Jue Wo Ban— these... top-tier combatants—and go head-to-head?"

Forget the Four Saints of the Underworld.

This must be confronted! These four are a greater threat than the Underworld itself.

Four beings on par with Su Han— just thinking of them made his scalp tingle. Only someone with a clear grasp of his own strength could fathom just how terrifying they might be.

Hou Jue Wo Ban and Bai Hu Zi may have originally been Grand Master-level beings.

But after their enhancements, they have touched the threshold beyond Grand Master, barely qualifying as Saint-level combatants.

Aizen Sōsuke needs no explanation.

He is absolutely worthy of Saint-class status.

Yu Qiyu and Qi Mu Nanxiong— these were Su Han's double insurance.

If he couldn't win, these two would surely step in.

After all, Su Han always felt their combat power surpassed Earth's Saints.

After all, they're cheat players! Push
