Lin Wei, a modern toxicologist, was reborn in the Blue Star Realm where "technology and immortality are integrated". Here, immortals are classified by "spiritual root gene testing", elixirs need to be synthesized by "molecular refining instruments", and the progress of cultivation is monitored by "spiritual power data panel". However, the "Tiandao Sect" that monopolizes all this is actually using mortals to conduct "spiritual root transplant experiments". Lin Wei holds the knowledge of modern chemistry/toxicology and counterattacks from the bottom, uncovering the conspiracy and rebuilding the order of immortality.
