God of Card Making

This is a rare card-making type of food since Fang Xiang's "Card Tutor". The protagonist is not a time traveler, does not have a golden finger, is an orphan, lives a difficult life, and is surrounded by mostly bad people. What has been revealed so far is that his card-making talent is a genius among geniuses. He is self-taught through his own efforts. While the first teacher provided him with card-making resources, he also stole his results for his own benefit. The only person who thinks about him is Annie, a companion in the orphanage who was adopted by an old man in the name of his daughter when she was a teenager. The current style is relatively dark, there are almost no good people, and no one helps the protagonist. It's an unconventional and cool story, but I think with the talent of the protagonist, when the card-making level is high, he will probably kill everyone, and there will naturally be more good people.
