mother is the family sex slave story

The MC has a system that gives him a point to invest in a skill everyday. He rapidly improved his calligraphy to a level that shocks the miss of duke family in a few days, so each point is quite useful. Despite that, the MC is a person who shrugs off every form of disrespect and is immensely grateful and obedient to his slave owner. The MCs mother died and her brother left to take up official duties, then his mother in law imprisoned him and banned him from learning for years or taking the official examination since he was talented. Now his wife’s family bought him like a slave and imprisoned him. After trying to escape he rubbed in pig shit and forced to copy the family rules a thousand times. The MC is grateful to be sheltered and fed, and acts smug when praised for his calligraphy… The predictable development of the novel is that the MC is an obedient slave who uses the strength he secretly develops to aid his slave owner family and wife. The novel should be renamed to ‘Slave Immortal’.
