The Demon Sect's Useless Old Man Was Refined into a Peerless Medicine by His Senior Sister

Chen Shi, who traveled across the Tianyuan Continent and spent eighty years safely in a small mountain village, was about to be buried when he was captured by Hongluan Peak disciples Han Fei'er and Han Shuang'er, believing that he was a pure Yang body that was unique in thousands, and was used as a medicine guide. After three days and three nights, everyone lost weight! Just when Chen Shi thought that his life would be in the hands of these sisters—— The Yin-Yang Mirror has awakened! Abandoned elixirs and incomplete magic weapons can be turned into treasures and decay into magic by consuming the Yin and Yang profound energy. The yin and yang profound energy can only be obtained through dual cultivation. What's even more domineering is that the Yin Yang Mirror also comes with two magical powers. Love Gu Seal: When practicing dual cultivation, the other party's favorability will be increased. When the favorability reaches the full value, the other party will absolutely surrender to the host. Mind power: By touching the other person's body, you can know the fear in their heart and see through their inner demons! Han Fei'er's inner demon: [There is only one month left. If you cannot break through the foundation, you will become a furnace for the inner disciples and be harvested until death] Han Shuang'er's inner demon: [On the surface, he is ruthless and cold, but in fact, he is fragile inside. Every time he kills, he tortures himself. He just wants to become stronger and protect his sister] Duan Hongyu's inner demon: [Practice the forbidden art "Yuan Devouring Art", and your lifespan is less than one month. If you can't break through the foundation building, you will definitely die] Su Muyun's inner demon: [My sister was harvested by Huo Dong until she died, and no bones were left. I just want revenge, but I am haunted by inner demons and my cultivation level is declining] … From then on, I spy on my inner demons, grasp the goddess, and conquer them one by one! Want me to help you break through your bottleneck? Repair meridians? Suppress inner demons? Chen Shi: "Sorry!" "If you want my help, you have to be a double cultivator!" "Money and women - I want both!"
