The job change is a bizarre and calamity; the nation begs me to tone it down.

The black-robed youth in the sky seemed to sense Gu Xu's change.

He looked down at the figure kneeling on the ground, struggling in pain, as the beam of light seemed to crush him.

The taut lines on that illusory face suddenly softened.

He looked at himself now and showed a look of extreme satisfaction.

Even with a relieved smile.

"You succeeded! Now, you'll have to walk the rest of the road by yourself!"

He knew that he had come here across the long river of time, paying an irreparable price, and that all his perseverance and hard work had finally borne fruit at this moment.

With his old mind back in place, Gu Xu at this point in time has completely crossed the most difficult threshold.

He has no regrets.

Next, we should eliminate the last remaining hidden dangers.

The black-robed youth's eyes sharpened again, and a resolute will to die erupted from his increasingly ethereal body.

He ceased maintaining the black barrier. The instant the barrier vanished, a purplish-black beam of light slammed directly into him.

But he was not immediately erased.

All the remaining power within him was ignited at that moment.

It was an ultimate burning that transcended levels and professional limitations.

His soul, his karma, and all traces of his existence in this world were transformed into the purest fuel.

"drink!!!"

The black-robed youth let out a roar that shook the entire dark side of the moon, braving the pillar of light that was capable of destroying everything.

His entire body transformed into a blinding black light, rising against the current!

The giant eye seemed to sense the ant's mad intentions. Its pupils suddenly contracted, and the power of the purplish-black beam of light doubled again, attempting to crush him completely.

But it was all in vain; the black-robed youth's speed had already broken through the shackles of space.

He was like a sharp sword tearing through the night, piercing straight into the very center of those two high-dimensional giant eyes in the sky!

"boom--!"

There was no earth-shattering roar, only a terrifying tremor as if the entire world was about to collapse.

The black-robed youth used all his strength and detonated himself the instant he made contact with the giant eye.

He used his own soul, forged through countless trials and tribulations and having devoured countless terrifying beings, as a high-yield bomb.

An extremely bright light exploded in the sky, obscuring all vision.

Those towering, high-dimensional eyes emitted painful fluctuations amidst this self-destructive explosion that consumed everything.

Large cracks appeared on its surface, and large gushes of golden blood, exuding a high-dimensional aura, gushed out from its eye sockets, like a golden rainstorm.

The giant eye was severely damaged.

Unable to maintain its projection in this realm, the cracks began to heal rapidly, and with endless anger and weakness, it retreated in a sorry state to a higher dimension.

The sky returned to its somber gray color.

The young man in black robes also vanished completely in this spectacular explosion.

He left not a single piece of clothing, not a trace of breath, as if he had never existed in this world.

He paved the way for Gu Xu by completely annihilating himself.

Gu Xu knelt on the ground, tilting his head back, staring through the bloodstains on his face at the spot where the black-robed youth had disappeared.

His heart clenched violently at that moment.

It was an extremely strange and unbearable pain, not physical, but causal.

To put it another way, it's the emptiness of having personally severed a part of one's own destiny.

Gu Xu knew that his future self had been completely erased from all timelines of the past, present, and future.

They don't even have the right to be remembered by others anymore.

But he had no time to lament, nor the right to be weak.

The one who paid such a terrible price was not there to see him grieving here.

As time went by, the excruciating pain in my mind began to recede like a receding tide.

The old brain has been completely integrated with him.

Instead, there was an absolute clarity and an unprecedented sense of control.

He felt that his brain was no longer flesh and blood, but had become a supercomputer with unlimited computing power.

With just a glance, he can easily analyze any rule or energy fluctuation in the world.

The flow of wind, the convergence of energy, and the weak points of space.

Everything was clearly visible to him.

The system's blood-red notification sound began to flood the screen.

[Ding! Fusion successful!]

[The old jigsaw puzzle (2/???) has been returned to its original place!]

[All objectives for the third job advancement have been achieved!]

[Congratulations, host! All third-tier advancement quests are complete!]

[Professional advancement successful! You have been promoted to: Tier 3!]

[Level restriction removed! Current level limit: LV40!]

[Gain unique passive skill: Brain of the Ancients!]

Lines of blood-red data danced wildly before Gu Xu's eyes, the handwriting distorted, like some kind of living thing.

It exudes an ancient and mysterious aura.

Gu Xu slowly stood up and casually wiped the blood off his face with the back of his hand.

His gaze deepened, as if it could pierce through the void.

With a thought, he immediately brought up the newly refreshed skill panel.

【Name: The Brain of the Past (Incomplete/Core)】

[Rank: ??? (Not visible)]

[Status: Awakening/Fusion]

[Introduction: It is the wellspring of wisdom from the ancient rulers, carrying forbidden knowledge that transcends time and space. It can see through the patterns of fate and set the gears of time in motion.]

[Effect 1: Time Reversal (Active) - By paying a certain price (permanent attribute deduction/mental energy overdraft), time can be reversed for a specified target or a small area. The price depends on the duration of the reversal and the strength of the target. Cooldown: 7 days.]

[Effect 2: River of Time (Active) – At the cost of the complete annihilation of life and soul, break the ironclad laws of dimensions and transport your state or consciousness to a designated past or future point. This process is irreversible; after use, you will be completely erased from that timeline. (Note: Time is a long river, and you are the madman who dares to go against the current.)]

Gu Xu looked at the two skill effects on the panel, his pupils contracted slightly, and he took a deep breath.

The cold air around him filled his lungs, but it couldn't suppress the turmoil in his heart.

He now clearly understood how the young man in black robes had gotten here.

That was by no means an easy time travel; it was in a desperate future where the future self was driven to the brink of despair.

In order to reverse his inevitable demise, he activated the "River of Time," sacrificing all his life, soul, and every trace of his existence.

He gave everything just to return to this point in time and shield his present self from the attack from the higher dimensions.

Clear away the obstacles around the brain from the past.

This is no ordinary skill; it's a last resort, a desperate measure used only when there's no chance of survival, a way to perish together with the enemy.

That version of myself was a complete madman.

And myself...

Perhaps I will become that kind of madman in the future.
