The missed dunk was really just an accident.
After all, Li Younan only had outstanding physical fitness; his system hadn't actually increased his basketball skills.
Those skills did enhance his coordination, core strength, agility, and even reaction speed, but the essence of ball-handling skill is muscle memory built up day after day through training, and the system hadn't granted him that muscle memory.
Li Younan could dunk before, but he had never tried this kind of between-the-legs dunk.
People who dunk a lot know that dunking looks hard, and in reality it's anything but simple.
If someone has never dunked before, even with enough vertical, getting the ball cleanly into the hoop is not easy; if the angle is off, it's very easy to send the ball flying.
Landing, standing under the rim, Li Younan stared up at the hoop, zoning out a little as his mind naturally started breaking down his takeoff motion and the angle of the dunk just now.
