Zhang Yi, the prime minister's son, was originally a great warrior, but his pedantic father forced him to study and gain fame. He had no choice but to hide at home and sell kitchen knives on the street. Unexpectedly, the kitchen knife he created turned out to be a peerless magic weapon. He accidentally alarmed the current emperor and was regarded as the emperor's teacher. Only then did the pedantic father realize that his son had already become a being inferior to one person and superior to ten thousand people.
