- Description from novelbuddy

Opening his eyes after transmigrating, Chen Yi found himself kneeling in the Punishment Hall of the Marquis’s Manor. The reason? As a live-in son-in-law, he had actually dared to run away on his wedding day.Consequently, not only was he thoroughly despised by the entire manor, but he was also indefinitely grounded as punishment.However, Chen Yi was more than happy to enjoy the peace and quiet. Having exhausted himself with endless toil in his previous life, simply being a wealthy, idle son-in-law in this one sounded pretty damn good.From that day forward, relying on a Daily Intelligence System to passively harvest fortuitous encounters, he dedicated himself to mastering the zither, chess, calligraphy, painting, medicine, and even the Dao of fishing. He lived a supremely leisurely and blissful life within the manor.……Many years later, when the surrounding barbarian nations launched a massive invasion, Chen Yi—who had already reached the absolute pinnacle of perfection in the arts, medicine, and fishing—helplessly sighed. Stepping directly into the realm of a Land Immortal, he shocked the entire world with a single battle.Xiao Jinghong: “Husband, didn’t we agree you were just going to be an idle son-in-law? Why are you a Land Immortal?!”
