The image of the Allen Race slowly began to move; after putting on his tiger ring, he adopted a stance similar to boxing and started practicing moves one by one.
"Hmm…It doesn't seem that special." Li Zheng observed for a moment, only finding the image ordinary, not even able to see the finesse in the so-called Allen Race's techniques.
However, just as he felt disappointed, the image suddenly accelerated, and the tranquil Dark Realm echoed with the sound of techniques breaking through the air.
Whoosh!
Whoosh!
Whoosh~
Boom!
"Holy crap!" Li Zheng was horrified: "Did he punch out a sonic boom?"
He saw clearly that the sonic boom was caused by what seemed a simple straight punch. From his perspective, the speed wasn't fast; the previous punches that only created breaking-through-air sound were even faster.
[Curious about the principle? Then study hard!]
Old Pu gave his final advice, then fell silent, no longer influencing Li Zheng.
