A modern young adventurer accidentally transmigrates into the Da Dan Dynasty as a degenerate who does absolutely everything wrong: greedy, violent, and constantly beating people, swindling and cheating, hopelessly addicted to gambling, and completely uneducated. After transmigrating into the body of an ancient noble heir, he uses modern knowledge and his own abilities to build himself up step by step. He brings back his mother, the dynasty's Grand Princess, who had returned to the palace because of his own shameless ways and violence. He thrives in the ancient world, makes a fortune, marries several wives, and is enfeoffed as a prince and granted a noble title!
