The fallen merchant’s son, Cao Wutian, unexpectedly obtains the "Eternal Charm System" — completing daily tasks to unlock extraordinary martial arts and adventures. The more charming his temperament, the stronger he becomes at wooing girls!

From a street scoundrel to toppling a tyrant, when the system reveals the ancient supreme inheritance, this flamboyant young man is destined to dominate the nine provinces!
