Lin Xuyang, a time traveler, was a top ancient martial arts researcher in modern society in his previous life, and accidentally traveled to the world of martial arts. He possesses the peerless swordsmanship "Thirteen Styles of Heavenly Sword Art". This swordsmanship is extremely domineering. The sword can resonate with the spiritual energy of heaven and earth, and its power is unparalleled in the world. At the same time, the light skill "Fish Step" is unique in the martial arts. It seems careless, but in fact he walks on the wind, as fast as lightning. Pretend to be a pig and eat the tiger. Because he is well aware of the dangers of the world and wants to experience a life in the world "from scratch", Lin Xuyang deliberately hides his strength and pretends to be a rookie who has just stepped into the world, knows nothing but has "extremely good luck". In the process of pretending to be a pig and eating a tiger, he made mistakes along the way to eradicate evil spirits, and started a ridiculous and thrilling contest with all kinds of evil heretics.
