The Archduke's Songbird - Chapter 25: Her Pain

Doctor Jiang Fei, considered closing down the clinic because business was so bad, but unexpectedly his game character entered his body, making him omnipotent.

Not only is he superb in medicine, he also controls the life or death of the flesh bones of the dead person, and just like Yama he snatches people’s life.

He is now proficient in even cooking, playing piano, gardening, and domesticating pets!

People thought this was all of Jiang Fei’s skill, but Jiang Fei would smile and look at the martial arts cheats book. ‘The Dragon’s 18 palms’, ‘Six-pulse excalibur’, ‘Northern Profound Magic’, ‘Lone Solitary 9 Swords’
