Immortal Doctor Comes to Huadu

Li Zizai became a door-to-door son-in-law in Huadu, and was looked down upon by everyone. One day, he got the "Green Bag Book" given to him by an old beggar man, and he reached the pinnacle of his life. He stepped on big bad guys; people who looked down on him in the past came to please him; some beautiful heroes were willing to be his little sisters and brothers. As long as he wants, he can stand on the top of the world.
