Chapter 15: 3-Star Technique Card? Shocking the whole school! Head to the Archives!

In the cultivation room!

Behind Su Yu, the Card Controller space opened on its own.

Two Magic Card projections shining with golden radiance emerged.

At the same time.

Beside him, Agumon also sat cross-legged, imitating Su Yu's appearance.

Opening its big eyes, one stream of Source Energy after another gathered quietly in its body!

Finally, the moment Agumon's aura climbed to its peak!

"Roar!"

Agumon opened its mouth abruptly!

Then, a surging flame turned into a huge flame ball, carrying the peerless power capable of destroying everything in its path.

Toward the test slate Su Yu had prepared long ago in front.

It whistled and rushed!

"Boom!"

That Fireball Jutsu gathered from the vast Source Energy.

In an instant, it burned the test slate to ashes, and then, its momentum remained undiminished.

Under Su Yu's surprised gaze.

It directly smashed through the wall of the cultivation room before finally dissipating!

"What the..."

Looking at the scrapped cultivation room.

And then looking at the apologetic Agumon.

Su Yu couldn't help but blurt out a curse!
