Han Dong would never joke about his own life and he also trusted his instincts, decisively opting to dodge instead.
Indeed...
The most terrifying thing in the [Colosseum] was not the various beasts participating in the life-or-death combats, but rather the manager of this place.
The abilities the warden displayed, "Skull palm knife" and "Super Fast Regeneration," almost certainly confirmed one thing... The Black Water that induced the warden's abnormal transformation was definitely of medium, or even high quality.
Of course, it was extremely difficult to stably control high-quality Black Water, which also indicated that the warden himself was quite powerful.
If Han Dong had attempted to break free from the restrictions of the beast fight arena and make an enemy of the warden upon his arrival to the City of Gods, it would have been an outright surrender.
...
Due to his impressive performance during the spar, Han Dong had been allowed to participate in the "promote competition."
