Into the ruin!
Zayn didn't spend too much time picking the reward of his bet with Manager Tilan.
He found something that would be of great use in the future and told the old woman to bring the Artifact to the Colosseum.
The old woman noticed that Zayn was neither overly excited nor extremely nervous about the fight against the Chimera. She was not sure whether that was unfounded arrogance, ignorance, or if he was actually strong enough to defeat the Chimera.
The latter was the least likely. Even if Zayn had been strong enough to defeat the Blazing Sabertooth Tiger with a single attack, and the Heavy Armored Bull with his wits, the Chimera, crippled or not, was on a completely different level.
