Where Is the Sword in the Heart?

Yue Ling is really only twenty years old, and the burden on his body is extremely heavy. After hard training, most of the spiritual energy has to be used to feed the blood-sucking sword spirit living in the body. He worked hard to make money, but it was all eaten up by the useless greedy pet he picked up. I finally became a master, but I shamelessly like to take treasures from my apprentice's pockets... An ordinary time-traveling girl, carrying a burden, friendship and hatred, laughed and cried all the way, but never forgot why she held the sword in her hand.
