"Thunderbolts—cruel, destructive; to touch them is to turn to ash and smoke…"
Su Changkong was contemplating the characteristics of the Thunder Beast Emperor's power from their recent battle, and he stood up to practice the Five Animal Frolics, attempting to integrate the nature of thunderbolts into his boxing technique. This was undeniably difficult, demanding a prolonged period and repeated insights.
But Su Changkong was very patient. That day when he faced the Heavenly Demon, he was almost powerless to resist, left to be slaughtered. He absolutely did not want to experience that feeling a second time!
He at least needed to ensure that if he faced the Heavenly Demon again, he would possess the power to protect himself and not be easily crushed, like an ant being effortlessly pinched to death.
