Soul Ash Surpasses Ten Thousand for the First Time! The Boundless Potential of the Lin Character Technique! Arakawa Village No Longer Exists

Using the Fragment of the Ten-Span Sword as the sole object defining the Qi Sea would not result in low strength, nor would its future ceiling be low.

That was because it was part of a weapon from mythology.

In the future, Uesugi Tetsu could completely collect more fragments of the Ten-Span Sword, or even an entire Ten-Span Sword, to supplement the completeness of the defining object.

Using the entire Ten-Span Sword as the defining object would surely create a vast Qi Sea with killing power among the very best in the modern world.

So, how should he choose?

Uesugi Tetsu gave his answer without hesitation.

"—How could I be so short-sighted as to abandon the greater for the lesser?"

With a wave of his finger, he erased the prompt for the "sole defining object" before him.

Indeed, the sight of immediately converting potential into strength and expanding the Qi Sea dozens or even hundreds of times was tempting, and a clear path for future growth had been laid before him.

But doing so would mean losing his true potential.

For Uesugi Tetsu, what was his "true potential"?

"Demon Incarnation Cards."

There was no doubt about it.

Even the reason he had wanted to define his Qi Sea with Five-Element defining objects was because the two incarnation cards within it were incompatible.

—Establishing a stable cycle with Five-Element defining objects, then placing five incarnation cards with ever-improvable tiers into it... Their upper limit was simply immeasurable.

And at present...

Uesugi Tetsu stared at the fragment floating in the air, ruthlessly suppressing the two incarnation cards.

Hmm, the Fragment of the Ten-Span Sword did not seem to get along with them very well.

Perhaps the moment he designated it as the sole defining object, the two cards would be kicked out
