Chapter 623: The construction method of the Zanpakuto

"Rumble—!"

Heaven and earth trembled for it!

When in Su Yu's hand,

the last magic array circuit was completed!

The Source Energy of the entire Desolate Ancient Battlefield rioted for it!

Boundless Source Energy turned into flowing light, surging in all directions, making everyone feel unable to breathe!

Surging into that Magic Card stone slab!

However,

Su Yu's eyes were still incomparably calm!

"Still not enough..."

It was also at this time

that the clash between Shen Tianyu and the others and the Silver-Eyed Clan King had reached a white-hot stage.

No one was distracted to pay attention to Su Yu.

That momentum also covered up Su Yu's whisper.

Otherwise, if it spread out,

it would probably instantly cause a huge uproar! ===== CHAPTER 625 =====
