The protagonist Lin Xuan travels through the ancient world and discovers that the civilization of cultivating immortals in this world has reached a bottleneck. The techniques are obscure, resources are involution, and the laws of heaven are unfair. As a doctor of science and engineering, he resolutely raised the banner of "scientific cultivation of immortality", used mind maps to analyze exercises, used standardized processes to mass-produce elixirs, used spiritual force field theory to reconstruct formations, and even founded the "First Vocational and Technical College for Immortal Cultivation" to turn knowledge into the most powerful productivity.
