MTL - Dear Mr. Lu

Luo Wencheng made a deal with a certain existence and went back in time to ten years ago, when he had just been released from prison, still young and healthy, not yet pushed to the breaking point by Luo Wenjun and not yet used by him as a prop to test drugs for profit until his tragic death. This time he was going to trample Luo Wenjun underfoot. The first priority was to steal Luo Wenjun’s future backer from him. - Description from Novelupdates
