The novel begins with not much prior context. The MC’s name Yun Sang. in the first world, he awakens in a house on a rural mountain. He was kidnapped and sold at a young age to the mountain and was originally from the wealthy Jiang family. He saves the people kidnapped by his neighbor, one of whom is surname Han and is the ML. He is then found by his original family and the magpie who was switched at birth. The first world is then Yun Sang making a game company and succeeds in life. I don’t remember how the rest of the stories connect properly but I remember some chunk of worlds. There was one world where MC woke up as a sickly scholar who became the champion scholar in the national examinations and the ML was the amnesiac general. There was also one where MC was a priest and ML was a crown prince. It’s Chinese and the official work, if I remember, was completed.
