Lu Ben, an eighteen-year-old orphan, has been studying under his master Xuan Jizi in the mountains for fifteen years. He is an expert in medicine and martial arts, but he has never understood the world. One day, the master suddenly turned against him and drove him down the mountain. He only gave him an address and an old jade button. He came to the city full of grievances, only to find that he had five stunning senior sisters, each of whom was a master in his field - the business empress Shen Qingshuang, the medical sage Bai Zhi, the martial arts queen Mo Li, the technology genius Aizen, and the entertainment queen Su Wanqing. The five senior sisters doted on this little junior brother who fell from the sky to the core, and Lu Ben fell into the gentle land of the senior sisters. While pretending to be a pig and eating a tiger, he used the most "unfashionable" method to solve their problems, and at the same time, he could smell the huge shadow behind his life experience from his own name and tokens. It turns out that he is the orphan of the Lu family, a reclusive medical and military family that was wiped out fifteen years ago. The protection of the five senior sisters and the layout of the master are all tied to a bloody feud. When the truth was revealed inch by inch, Lu Ben, the five senior sisters, and the master who came out of the mountain stood side by side. The king returned, paid for his debt with blood, and finally found his belonging in this world in this gentle countryside.
