Bang bang!
When Grandpa Wu moved, his whole body constantly emitted explosive sounds, visible air currents turned into white circular ripples and spread out.
The tiny ripples continuously burst as Grandpa Wu moved, similar to the sound of a whip.
Li Xiu was slightly surprised; the explosion was clearly the sound burst after the body broke through the sound barrier.
Breaking through the sound barrier with speed is not surprising, Li Xiu can do it too, but for someone like Grandpa Wu to be able to break through the sound barrier with every move, that's not something everyone can do.
It's not difficult to break through the sound barrier with speed, but Grandpa Wu's muscles moving over extremely short distances can break the sound barrier, now that's a bit terrifying.
Watching the constantly exploding sonic booms from Grandpa Wu's body, Li Xiu's expression turned slightly more serious.
