Dragon Slayer: The Guardian

Twenty years ago, a dragon wreaked havoc on the mortal world until the Heavenly Master descended to save humanity and rescue a young couple, Jiang Fan and Liu Ruyan, taking them as disciples to inherit his will and protect peace. Jiang Fan inherited the Master's position, sacrificing personal freedom to remain at the temple and suppress the dragon. Twenty years later, the world has recovered, but some seek personal gain and want to demolish the temple, including Jiang Fan's junior sister, Liu Ruyan. Liu Ruyan has forgotten the dragon from her childhood and been misled by the villain Wang Tianlong, intending to destroy the temple where she has lived for over two decades to resolve her own destiny crisis.
