Although Fang Zheng learned from Fina why his attacks were ineffective against the Chaos Knight, the reason made him quite upset.
Alright, according to Fina, with the Order Seal, he indeed qualifies as a protagonist in the Main World.
However... this power actually shares the same origin with Chaos... Upon careful thought, Fang Zheng could understand. After all, according to the backup by the Goddess of Order, this Order Seal can only be used by the Goddess of Order's clan. This means the entire clan should possess this, but they were still obliterated by the outbreak of Chaos. It clearly shows that the Main World's Golden Finger isn't much help against Chaos.
But this can't be the case.
