Yang Yi had trained in combat, but unfortunately, not for long enough.
If you consider fighting a skill, then Yang Yi had only just glimpsed the entrance. His hand hadn't even touched the gate, let alone passing through it.
With his powerful memory, Yang Yi knew many standard fighting moves and terms, but he was unable to use them correctly as remembered in his mind.
It's like playing basketball; you've seen the stars' moves and can imitate them, but your shots are off, your breaks are not sharp, you can't even hold onto the ball properly. Merely mastering a posture without grasping the true essence of the technique is useless.
Yang Yi's fighting abilities didn't even reach half-baked, but what about the Boxing King? He weighed at least one hundred kilograms, and although only about 1.8 meters tall, slightly shorter than Yang Yi, his body was almost double the thickness of Yang Yi's, with arms as thick as Yang Yi's thighs.
