From the Start in the Siheyuan, Yu Li Stabs Me in the Back

Gu Chuan, a modern-day corporate drone, was working overtime late into the night when a car accident on his way home sent him transmigrating into the body of a man from the late 1950s who shared his name. Only after waking up did he discover that his meager family assets had been taken by his girlfriend, Yu Li. Not only had Yu Li registered her marriage to someone else, she had also ordered the ruffians of the courtyard to arrange for his Host to marry Chi Qing, a woman who had fled famine with her two younger sisters! Gu Chuan absorbed his predecessor’s memories and used the jade bottle that had brought him to this world to obtain a magical marrow space. He tempered his body with the immortal marrow, then drew on the traditional family medical skills his predecessor had learned and used the space’s water to concoct an exceptional health tonic. He outwitted the courtyard ruffians, established himself step by step, and built powerful connections. In the end, his extraordinary health tonic made him the most influential man in the world!
