This world is divided into three realms, the heaven, the human world, and the underworld. There are two ancient gods in the heaven, who can reach the heaven and the earth and are omnipotent. Yan Yu is one of them. Of course, His Highness lost one of the four greatest treasures in the heaven, the "Lian Lighthouse". This tower suppresses the ancient monsters. So Yan Yu went down to earth to look for "Lian Lighthouse"...
Intention: Don't worry about being ignorant of others in the future. No one in the world knows you.
