Fu Chen instantly replaced his body with a small piece of wood that was behind Hou Ming. Because Hou Ming doted those pieces instead of destroying them, he was quickly able to find a position of any required pieces of wood with ease.
Upon arriving behind Hou Ming, he raised his fist. Fu Chen was quite aware of the fact that right now he wasn't at his best. So, he couldn't rely on One Sword Art.
But, it didn't mean he couldn't do his best. During his time using One Sword Art, he had been focusing on creating a similar art.
Except, it doesn't need to be used by a swordsman. Just like how Wu Kong copied his martial art and made it his own, he also found a way to make a new kind of martial art from that sword art and other techniques and martial arts he had.
So, during the time when he was creating the Talentless Sword Technique, he focused on creating this new move as well. He was preparing it in case he and his team gets into deep trouble.
