Before crossing over, she was an environmental engineering Ph.D. student who had spent eight years deeply cultivating the direction of desertification control, and died suddenly in the laboratory on the eve of her thesis defense. When she woke up, she found herself lying in a carriage heading to the Western Regions for a peace marriage. Before she could digest the fact of crossing over, the prompt tone of the Oasis Project System sounded in her mind, detecting an extremely ecologically fragile area, with the host's survival countdown being 7 days. She met the man she was nominally supposed to marry, and immediately afterwards was cast into the cold palace because she used scientific theory to refute the priest. Lin Qing began to apply her knowledge in the cold palace, combined with the prompts given by the system to begin regreening, and continuously gained recognition through remarkable results.
