I, Dr Biazhu, am the owner of Bubu Pharmacy and my dear Qiqi's guardian. I am considered a master of the medicinal arts, though I don’t wish to flatter myself. I am also the latest recipient of a generational contract with my talking snake, Changsheng. I am in search to achieve immortality to ensure I am the last to ever bear this contract, saving potential inheritors and even Changsheng herself from the cost that comes with her power. I am faced with a Cronic illness but I will not hinder me.
