Chapitre 724: Chapter 697: Thousand Spirit Immortal City

The Hidden Spirit Island in the Vast Void Domain emitted a strange fluctuation.

The turbulent flows of time and space hidden beneath space began to slowly stabilize.

The whole Hidden Spirit Island emitted an incredibly dazzling blue light, and a sound like an engine starting began to resonate from within the island.

"How many horsepower would that be if we were to use that as a unit, Pu Tao?" joked Xu Fan, who was about to leave this bizarre area, hence his mood was inexplicably uplifted.

"Three hundred and sixty Heng He Sha of horsepower~" Pu Tao replied in a flat tone.

"Tens, hundreds, thousands, tens of thousands, hundreds of thousands, millions, billions, quadrillions..." Xu Fan thought, shaking his head, too lazy to calculate further. It was a lot, whatever the number.

At this moment, the disciples in the core world of Hidden Spirit Island also heard the noise.
