I Can Upgrade Everything Infinitely

Xu Qing was no match for the mirror Xu Qing at all.

"Time Treasure Tower!"

BOOM!

At the moment of crisis.

Xu Qing shouted, unhesitatingly summoning the Time Treasure Tower. The brilliant tower shot into the air and positioned itself above his head. It cast down countless curtains of light, enveloping him in its protection.

"Thousand Dao Transformations!"

ROAR!

The cry of a dragon rang out.

Xu Qing summoned the True Artifact: Thousand Dao Transformations, which transformed into a multicolored dragon, forming a second layer of powerful defense.

CLANG!

A sword chimed.

Xu Qing summoned the Carefree Sword. It transformed into countless Chaos Sword Lotuses, forming a third layer of defense.

Three layers of defense, stacked one upon another.

This would buy Xu Qing some time.

"Hahaha…"

The mirror Xu Qing let out a wildly arrogant laugh. "I will always have the same strength as you, the same methods as you, and the same Treasures as you."

"Under these circumstances."

"Do you really think these three layers of defense can stop me?"

"Absolutely ridiculous!"

BOOM! BOOM! BOOM!!!

The moment he finished speaking.

The mirror Xu Qing unhesitatingly unleashed his full power and strongest form. He deployed one powerful Supreme Treasure and True Technique after another: the Time Treasure Tower, Thousand Dao Transformations, Carefree Sword, and Eight Gates Root Technique.

BANG!

A massive crash resounded.

The Carefree Sword let out a mournful cry as it was sent flying.

In just a few seconds.

The mirror Xu Qing had already shattered the third layer of defense.

"Too weak!"

The mirror Xu Qing's voice was filled with mockery.

At this moment, Xu Qing was already sitting cross-legged. He showed no signs of panic. With a single thought, his consciousness connected with the Encyclopedia of All Things.

SWOOSH!

The next moment, the basic information for the Carefree Sword Dao appeared in Xu Qing's mind.

…

[Carefree Sword Dao Level 28: 441,223,527 / 20,480,000 (Upgradeable!) (...)]

…

"Upgrade Carefree Sword Dao."

Xu Qing commanded.

BUZZ!

The moment he spoke.

The Encyclopedia of All Things shone with brilliance as boundless Energy surged. Xu Qing's consciousness entered a profoundly mystical state, and his Power of Physical Immortality began to transform…

Physical Immortality.

It is divided into four levels: Early Stage, Minor Achievement, Great Success, and Perfection.

Currently, Xu Qing had just stepped into the first tier of the Ninth Realm: Undying Immortal Realm. This was known as attaining Immortality once, specifically: Early-stage Physical Immortality.

Next.

If Xu Qing wanted to break through further, he would need to continue perfecting his Physical Immortality, advancing from the initial Early Stage to Minor Achievement and then Great Success.

Ultimately.

He would reach Perfection.

Reaching Perfect Physical Immortality would mean that Xu Qing had fully attained Immortality once. If he wished to continue improving and breaking through, he would need to comprehend a second form of Immortality.

This could be either Immortal Soul or Immortal Will.

…

[Upgrade Successful!]

[Carefree Sword Dao Level 29: 420,743,527 / 40,960,000 (Upgradeable!) (You have further perfected your Physical Immortality, reaching the level of Minor Achievement in Physical Immortality.)]

…

[Upgrade Successful!]

[Carefree Sword Dao Level 30: 379,783,527 / 81,920,000 (Upgradeable!) (You have again further perfected your Physical Immortality, thereby reaching the level of Great Success in Physical Immortality.)]

…

[Upgrade Successful!]

[Carefree Sword Dao Level 31: 297,863,527 / 163,840,000 (Upgradeable!) (You have again further perfected your Physical Immortality, thereby reaching the level of Perfect Physical Immortality.)]

…

In the blink of an eye.

Xu Qing had raised his Carefree Sword Dao by three Levels, from Level 28 to Level 31. As the Level of his Carefree Sword Dao increased, his Cultivation and Realm rose accordingly. He had reached Perfect Physical Immortality, which meant he had attained Immortal Perfection once.

He had reached the Extreme of attaining a single form of Immortality.

Of course.

This was not over yet.

"Upgrade!"

Xu Qing commanded.

BOOM! BOOM! BOOM!

Instantly.

The Encyclopedia of All Things began to vibrate slightly, undergoing a new kind of transformation. An even more powerful Immortal Power began to surge from Xu Qing's body.

Countless ripples of power emerged from Xu Qing's body.

…

[Upgrade Successful!]

[Carefree Sword Dao Level 32: 134,023,527 / 327,680,000 (You have comprehended the Carefree Sword Dao even further, attaining Immortal Soul through the Sword Dao. You have mastered the Power of Soul Immortality and combined it with the Power of Physical Immortality, causing a qualitative transformation. You have mastered 'Dual Immortal Power' and stepped into the second tier of the 'Ninth Realm: Undying Immortal Realm,' known as the Early-stage of the Two Great Immortal Realms.)]

…

RUMBLE!

Sure enough.

The moment the Carefree Sword Dao finished upgrading, Xu Qing broke through at almost the exact same time. The powerful aura generated by his breakthrough actually sent the mirror Xu Qing flying.

"What?!"

The mirror Xu Qing's eyes flew wide. His face was a mask of utter disbelief; he couldn't believe what was happening at all.

"Impossible! This is impossible!!!"

The mirror Xu Qing shrieked.

"Nothing is impossible."

Xu Qing opened his eyes and slowly rose to his feet. His body began to radiate both the Power of Physical Immortality and the Power of Soul Immortality.

However.

The two great Immortal Powers fused, evolving into the Dual Immortal Power. This new Power was incredibly potent, exuding a crushing pressure.

In fact.

Just moments before, the mirror Xu Qing had broken through all three of Xu Qing's defenses. The Carefree Sword, Thousand Dao Transformations, and Time Treasure Tower had only held on for half a minute before being shattered.

The mirror Xu Qing had defeated all three layers of his defense.

Originally.

The mirror Xu Qing had been about to deliver the killing blow.

But then.

Just in the nick of time.

Xu Qing broke through. In only half a minute, he had achieved several breakthroughs in a row, ultimately attaining the Two Great Immortals.

With this.

Xu Qing's power had increased dramatically.

CLANG!

A sword chimed.

Xu Qing raised his right hand. The Carefree Sword flew back into his grasp, unleashing an unparalleled Mighty Power of the Sword Dao. The Time Treasure Tower and Thousand Dao Transformations also returned to him.

Most importantly.

The might emanating from these three Supreme Treasures was far stronger than before.

Clearly.

The stronger Xu Qing's power and the higher his Cultivation, the more of the Supreme Treasures' and True Techniques' Mighty Power he could unleash.

For example.

A knife in a child's hands can't display much of its power and might even injure the child. In the hands of an adult, however, it becomes a deadly Sharp Artifact.

Of course.

If that same knife fell into the hands of someone skilled in a Saber Technique, it would be even more terrifying.

The principle was the same.

"Nothing is impossible."

Xu Qing's expression was calm. He shook his head, his gaze falling indifferently upon the mirror Xu Qing as he spoke in a flat tone, "You wanted to kill me and take my place?"

"Now I'm standing right here. Can you do it?"

Clearly.

The Mighty Power of the Encyclopedia of All Things was something the mirror Xu Qing could not replicate. While Xu Qing had broken through repeatedly, the mirror Xu Qing could not; its Cultivation remained the same as Xu Qing's had been before his breakthroughs.

"I don't believe it!"

BOOM!

The mirror Xu Qing roared, bellowing furiously, "You couldn't have broken through so many times in such a short period! You absolutely cannot have reached the Two Great Immortals!"

"Die!"

SWISH!

The mirror Xu Qing launched an attack. A terrifying Mighty Power erupted, and Xu Qing could finally experience firsthand just how monstrous his own original strength had been.

There was only one way to describe it.

It was too strong.

Simply too strong.

'No wonder I was able to kill enemies in higher Realms back then.'

BANG!

The sound of an explosion rang out.

But unfortunately for the mirror image.

The post-breakthrough Xu Qing was even stronger, even more monstrous, and his power was even more terrifying. He completely overwhelmed the mirror Xu Qing.

With a single downward slash of his sword, Xu Qing, with the ease of snapping a dry twig, completely routed the mirror Xu Qing's barrage of attacks. Every single one of its assaults was crushed.

"Ah!!!"

A miserable scream rang out.

The mirror Xu Qing was sent flying, spitting blood. Its body, like some kind of special glass, began to show a web of fine cracks.

"You… you…"

The mirror Xu Qing was filled with terror.

"It's time for this to end."

Xu Qing said calmly.

Then.

Xu Qing raised his right hand. From his palm, the multicolored dragon formed by the Thousand Dao Transformations soared into the air, swiftly taking shape.
