When the End of the World Comes, I Actually Start Cultivating Immortality?

In 2150 AD, fifty years after a meteorite fell on the earth, alien phenomena permeated the earth and monsters arose. There were only a few million people left on the earth, huddled in the three major bases of China, Brahman, and the United States. Heterogeneity is the source of evolution of monsters and beasts, but it is the deadly poison of mankind. The crisis of survival is approaching step by step. Lin Yan, a life sciences researcher at the Huaxia Base, has spent his life studying heterogeneity but has repeatedly hit the wall. He has witnessed his relatives and friends being killed by monsters, and has fallen into a desperate situation. Once when sorting out ancient books, he accidentally came across the "Tao Te Ching", and an idea suddenly occurred to him - the heterogeneity was actually a mutated form of the aura of heaven and earth! Relying on the logical deduction and data analysis of scientists, Lin Yan used Taoist methods as a guide to break the limit of human tolerance for heterogeneity, successfully transformed heterogeneity into the aura of immortality, and embarked on a desperate journey to immortality. He optimized his skills, combined with technology, and upgraded faster than ordinary people. He counterattacked all the way from Qi refining to minor cultivation, slapped the technological faction in the face, defeated the provocations of the United States, and subdued high-level monsters. From guarding the Chinese base, to unifying the human federation, to decisively fighting against the Ocean Demon Saint, Lin Yan used science to prove the truth, used immortal power to break the situation, and finally overcame the tribulation and became an ancestor.
