Legend of Twelve Realms

In order to enter the royal library, a scholar was forced to start practicing swordsmanship from the lowest level, the "Pig Realm", to gain points. When he collected twelve mysterious bronze medals, he discovered that they were the key to summoning the ancient demon god. The former brother turned out to be an undercover agent, the accounting room next to him hid a shocking secret, and the rival girl also shouldered a mission. From raising and driving pigs to a decisive battle against the world-destroying demon, he must use the sword in his hand and the Tao in his heart to settle the accounts of this troubled world in the arena and the court.
