Don't Be Like the Koi Carp Singing Back

In order to change the fate of his sister's death, a young man made reckless mistakes, broke into the forbidden area, killed his best friend, and released the witch. Along the way, everyone sacrificed for him. However, the young man's indecisive character caused the entire royal city to fall into a long sleep after resurrecting his sister. In the end, the girl died in his brother's arms, the maze collapsed, the fog dissipated, and the royal city was deserted. Only the lonely king was left guarding a pond full of koi carp to grow old alone. Mr. Hongyan asked for books in vain. In the past, no one played the harp and harp. The years are over and the tears flow in vain. Do the young people here remember?
