Scratch Seth's earlier words on Zuroc just being stronger than Edwin, despite giving off qi that should put him at the solid stage 9th Kaiser level, Zuroc was leagues stronger than Edwin whom Seth was sure was at the same level.
Despite losing the ability to cast destructive and earth-turning qi techniques, Seth could always rely on his superior strength to deal with the enemy, but Zuroc was proving not to be one of such enemies.
Though his strength clearly fell short of Seth's, it was nothing to scoff at, and with the two kicks which he had received from the man, Seth could vouch for his strength.
Though they hadn't begun using their qi, Seth could already see his head leaving his shoulders if things continued as they were.
If he couldn't beat the man in a contest that involved Seth's strongest point, then how could he handle the man when he began incorporating qi in his attacks.
