This sort of challenge was a bit like a hand-locking spar between Martial Artists.
Unless they shared a deep-seated hatred, a full-power exchange could easily result in an uncontrollable situation leading to injury or even death.
So, for safer sparring, some Martial Artists invented hand-locking, a contest where they only use their forearms to collide, testing who has the superior technique.
The man who wanted to challenge Guan Tong now had the same idea.
For those who practiced Psychic Power Flow, victory was determined through physical contact. Whoever could use their Psychic Power to interfere with, or even disrupt, their opponent's natural flow would win.
This type of challenge required no special venue or time; it could happen right here, right now.
"Come on, young man!"
The man shot his hand out, his movements swift. It was clear he was annoyed.
