Yan Lan's identity as a martial arts master was abolished by a car accident three years ago, and he is now working as a workhorse in an office building - until he was pinned to the ground and beaten violently for ten seconds by a gangster. The master's life-threatening call came: the sect was destroyed, and the master was sent to the ICU. Before his death, he passed on a bug-level skill that could turn a sports car into a skateboard by "turning his inner strength into a horse".
He originally thought he was a waste, but when the female CEO of the largest conglomerate in the capital came to visit in person and offered him a billion to beg him to be his personal bodyguard, Yan Lan realized that it turned out that the martial arts practitioners in this world had already crushed technology into slag by relying on their inner strength. From then on, he punched the vultures of capitalists, kicked foreign masters, and made those who once laughed at him as "wasted" kneel down and call them ancestors.
This is contemporary martial arts - no matter how rich you are, just take my slap first.
