Our MC who can't cultivate works as an alchemist's assistant among many other odd jobs he does to earn his livelihood and desperately tries to find ways to enable himself to cultivate, although he is brilliant he is not valued in his clan due to him being cultivation-disabled. When he tries to buy an elixir which could awaken his 'inner eye' (something like sharingan, byakugan and rinnegan, but this novel contains 104 types with the 104th type being the weakest!) as a last ditch effort with the help of the alchemist who he works for, he finds a resonance with one of the awakened souls residing inside a painting in the pavillion which sells elixirs. He discovers that the awakened soul is of a person who is described as the 'Legendary Alchemist' without whom the alchemy wouldn't be as advanced as it was today, from the awakened soul he learns that there are still another 8 souls in the painting which are in deep slumber!. The soul also makes a shocking revelation to the MC about his condition and agrees to help him provided he becomes it's apprentice and the MC agrees... which is the start of a great adventure...
