Chapter 687

"This is really making me, conflicted..."

Su Yu was somewhat helpless.

Strictly speaking.

He, who possessed the 【GN Drive】.

In terms of spiritual energy recovery.

Let alone on Blue Star.

Even if placed in the entire vast universe.

At the Star Spirit rank.

He was absolutely a top-tier prodigy!

But he couldn't help it.

The consumption brought about by Ryujin Jakka after Bankai was too great!

As for the reason.

Su Yu guessed.

"It might be because the power used by Ryujin Jakka belongs to another nature!"

Spiritual energy or Source Energy, essentially, are both tangible transcendent powers!

But as the weapon of the Soul Reaper, the Zanpakuto.

It uses the power hidden in the so-called 【Soul】, which is more inclined toward the spiritual level!

In other words.

When Su Yu, or Gallantmon, mobilizes the power of Ryujin Jakka, they need to further convert the spiritual energy in their body into Soul Reaper power.

This causes excessive energy consumption.

This is also why.
