Li Yiheng, a doctor of biology, went deep into Wumeng Mountain to search for the legendary special medicine "Blue Fairy Clothes" in order to save his mother who was in the advanced stage of Parkinson's disease. He accidentally fell into a rift in time and space. When he opened his eyes again, it was the Liaoren Mountains of Chuanxia Road in the Northern Song Dynasty in 988 AD.
Without a system or martial arts, he only had knowledge of plant classification, microorganisms, and biochemical pharmacology. The sumac, wasps, and poisonous weeds in the mountains and forests all became weapons for his survival.
After being taken in by the demoted minister Li Mu, he recognized his deceased grandson's identity and heard a strange story from the old man passed down from five generations: Many years ago, a strange person also built an utopia here. This person left four notes scattered around the world, which seemed to be related to the blue light that allowed time travel.
Thus, a long journey from Liaoshan to Bianjing, and from the wasteland to the court began. Some people gather because of him, and some people disperse because of him. He repaired farm tools, fought against plagues, opened salt fields, and put down rebellions. The study of studying things quietly took root in the Song Dynasty. But no matter how far he walked, he always carried those pieces of blue fairy clothes and a map to go home in his arms.
Can he return to the present day?
