My Wife Studied Fang Xiandao

Fang is the way to find the way, and Xian is the immortal immortal. Fang Xiandao is a group of people who are looking for Taoism and immortality. Among them, monks from the three sects of Xingqi, Yiyi, and Fangzhong have the most number of monks. My wife studied under the Fangxian Taoist Fangzhong sect, and she can become stronger by practicing both. And I have a "single dog system", and I can become stronger by refusing to practice dual cultivation. Something seems not quite right...
