I, {Lin Chen}, am the adopted son-in-law of the Su family. My life has been worse than that of a dog for three years. Even my parents-in-law think I am not worthy of my wife, Su Wanqing, who is the college beauty. Until a series of weird things happened at Jiangcheng University - the library was haunted late at night, and students in the laboratory building disappeared mysteriously. I accidentally activated the [behind-the-scenes operation system]: secretly changing the supernatural plot can get rewards and unlock the heaven-defying medicinal formula! On the surface, I am a submissive and soft-boiled man, but in fact, I am working behind the scenes to strengthen myself with health-preserving medicinal diet and secretly protect Wanqing. The hypocritical president Qin Hao has hidden murderous intentions. There are martial arts masters who practice black magic hidden deep in the campus. The supernatural incidents are becoming more and more dangerous. Wan Qing may seem elegant, but she always reveals her foodie nature when I am making herbal meals, and her success will be ruined with just one mouthful of soup. Pretend to be a pig and eat the tiger, maintain your health with medicinal diet, and operate behind the scenes! Not only do I want to uncover the truth about the weird things happening on campus, but I also want to protect my foodie wife and impress all those who look down on me! Campus supernatural + medicinal diet health, the counterattack of the son-in-law starts from behind the scenes!
