Metal is for defense, Sound System is for long-range attacks, and even by itself, that lion was already giving Zhou Tian a tough time. Little did he expect that the lion would still have such tactics at its disposal. Although it looked like a Metal Rule ability, just based on the lion's displayed prowess, Zhou Tian truly couldn't muster a shred of confidence to claim he could defeat this opponent.
However, Zhou Tian knew he had to fight regardless, and although the lion repeatedly performed beyond his expectations, displaying strength that surprised him, with Diligence's efforts, Zhou Tian managed to gain some understanding of the lion's abilities after countless probing attempts. Although not entirely confident, Zhou Tian had already devised a method to capture the lion.
Once he had such a plan in mind, Zhou Tian quickly took action.
