The Demonic Sect's Discarded Elder Was Refined by His Senior Sister into a Peerless Elixir

After transmigrating to the Tianyuan Continent, Chen Shi spent eighty peaceful years in a small mountain village. Just as he was about to die, Han Fei'er and Han Shuang'er, disciples of Hongluan Peak, mistook him for a one-in-a-million Pure Yang body and seized him to use as a medicinal catalyst. Three days and nights later, he was so emaciated he was barely recognizable! Just as Chen Shi thought his life was about to end at the hands of these two sisters... The Yin-Yang Mirror awakened! Abandoned pills and damaged treasures could be turned from trash into treasure, and from ruin into wonder, by expending Yin-Yang Essence. And Yin-Yang Essence could only be obtained through dual cultivation. Even more overpowered, the Yin-Yang Mirror came with two divine abilities: Love Gu Mark: Raises the other person's affection for the Host during dual cultivation. Once their affection reaches the maximum, they will submit to the Host absolutely. Mind Insight: Touch another person's body to learn what they fear and uncover the demons in their heart! Han Fei'er's inner demon: [She has only one month left. If she cannot break through to Foundation Establishment, she will become an inner disciple's cultivation furnace and be drained to death.] Han Shuang'er's inner demon: [Cold and heartless on the surface, but fragile inside. Every time she kills someone, she torments herself. All she wants is to grow stronger and protect her sister.] Duan Hongyu's inner demon: [She cultivates the forbidden art, the Essence Devouring Skill. With less than a month to live, she will die unless she breaks through to Foundation Establishment.] Su Muyun's inner demon: [Her younger sister was drained to death by Huo Dong, leaving no remains. She wants only revenge, but her inner demon haunts her and her cultivation has fallen.] From then on, he peered into inner demons, brought divine maidens to heel, and won them over one by one! Want me to help you break through a bottleneck? Repair your meridians? Suppress your inner demons? Chen Shi: "I'm afraid not!" "If you want my help, we'll have to cultivate together!" "I want both money and women!"
