This Cultivation is Unscientific

Lin Yang was originally the Master of the Tianshi Temple; to mend the Heavenly Dao, his primordial spirit dissipated, and he accidentally transmigrated into a Lin Yang on Blue Star who shared his name. Blue Star worships magic, disrespecting the Three Pure Ones and the Great Dao. The Lin family's adopted son, Lin Dong, with the favor of his eldest sister and father, seized Lin Yang's innate spirit crystal and framed him, eventually causing the original owner's tragic death. After transmigrating, Lin Yang awakened the Demon-Slaying and Dao-Defending System, deciding to avenge Lin Yang, set things right, strike against evil magic cultivators, and revitalize the Great Dao.
