In 2025, young medical genius Lin Yu was conducting a mysterious experiment with spacetime energy in the lab when he accidentally triggered a spacetime vortex. A strange light swept him inside, and when he came to, he found himself on an unfamiliar ancient battlefield. War raged all around him, battle cries thundered, and soldiers swung their swords and spears as blood flew everywhere. Terrified and at a loss, Lin Yu was knocked to the ground by a wounded soldier in the chaos. Just as he thought he was about to die, a mysterious old man dressed in white appeared. With a casual wave of his sleeve, the flames of war around them seemed to be suppressed by an invisible force, and the battlefield fell quiet. The old man helped Lin Yu up and looked into his bewildered eyes. “Young man, your arrival here must be fate. This continent is suffering from both plague and war. Perhaps you can change everything.” With that, the old man vanished in a flash of light. Lin Yu knew he was in a dire predicament, but remembering his medical knowledge, he silently vowed to survive in this world and find a way back.
