How powerful…
Ai Hui was bewildered.
He had the best seat in the house, which allowed him to see much more than anyone else. He was both a spectator and an actor. Protected by the sword embryo, he was able to spectate the battle from an excellent perspective. Since Chi Tong was using his body, Ai Hui was also able to experience the various changes that occurred during combat. This allowed him to have a feel of the nuances in his moves as well.
The two rounds of intense combat were over in the blink of an eye, but the experience left Ai Hui in awe.
