Lin Yuanzhou is a medical student who has not yet graduated. His biggest worry is the final exam tomorrow morning. Then he traveled through time.
Not ancient times, not the future, but a parallel world called Blue Star - where there is a gap in Chinese history, Shennong, Bian Que, and Hua Tuo have all been forgotten, and people can only get sick by dancing to the gods and drinking talisman water. A five-year-old girl had a high fever that wouldn't go away. The fever lasted for three days and got worse and worse. The villagers were helpless.
Lin Yuanzhou knelt down, touched her forehead and said, "I'll do it."
He used leek juice to cure the mercury poisoning of the whole village, used silver needles to relieve the little girl's high fever, and spent three days and three nights without sleep to prepare a serum to fight the plague. He thought he was just an ordinary doctor who looked down upon people's death.
Until he learned that the fate of the world was tied to an arena—countries summoned gods to fight in a melee, with the winner gaining national destiny and the loser ceding their territory. Because there is no god to call upon, China has been at the bottom for three hundred years. Its territory has been cut off, its people are trapped, and its medical knowledge has been forgotten.
Lin Yuanzhou stood on the ring. He had no sword or gun in his hand, only a fragment of the divine contract and thirty G's of medical textbooks in his mind. When the gods of medicine from other countries released poisonous fog that filled the sky, he recited the "Shen Nong's Materia Medica"; when the arena was shrouded in poisonous fog, he planted a forest of medicinal herbs; when the gods of the twelve countries joined forces to besiege him, the shadows of Shennong, Bian Que, and Hua Tuo appeared behind him.
The whole crowd knelt.
