Eco-Doctor Unifies the Heavens

Dr. Lin Yuan accidentally transmigrates to a fantasy world where spiritual energy is clogged and the land is polluted. This world follows a dualistic law of spiritual energy and filth, where reckless exploitation and pollution have spawned toxic mists and acid rain, causing frequent natural disasters. Cultivators can grow stronger by draining the mountains and rivers, but the common people suffer from constant pollution. Armed with a complete modern scientific system, Lin Yuan starts from a remote exile village, making his mark by cleaning up Blackwater Lake, building filtration systems, and improving recycling workshops to solve the survival problems of the lower classes. Every time he purifies water and soil or restores forests, he earns heavenly merit, earthly blessings, and the people's faith, helping him break through cultivation realms like Dust Purification and Root Establishment. He also discovers the ancient Pure World Sect's legacy and establishes the Nature Academy to spread ecological ideas. As his pollution-control territory expands, he cleans up entire rivers and pushes for legal reforms at the court, but this stirs the interests of aristocratic families, sects, and the old imperial power. When these forces unite to suppress him, Lin Yuan cultivates tree guardians, rallies the people's faith to create a unique natural domain, and sparks a civilizational revolution with circular economy concepts. The old forces release a millennium-old source of filth, causing a catastrophe. Lin Yuan rushes to the Eye of Ten Thousand Filths, confronts the Filth God, and comprehends the law of balance and symbiosis. After the chaos subsides, he builds a new civilization that merges technology with fantasy and promotes harmony between humans and nature. — Description from novelcodex.org
