Reborn in the Flames of War: China

In the summer of 2023, physics graduate student Chen Feng insists on completing a quantum teleportation experiment during a thunderstorm. He is struck by an anomalous bolt of lightning, and when he wakes, he finds himself in the mountains of North China in 1940.

The Eighth Route Army's guerrillas discover Chen Feng and nearly execute him as a spy. At the critical moment, he saves himself by playing the national anthem on his phone and demonstrating his modern knowledge.

Political commissar Zhao Gang comes to tentatively believe Chen Feng's claim that he is a “scientist returned from overseas” and takes him to the headquarters of the Shanxi-Chahar-Hebei Military Region.

On the way, they encounter a small Japanese unit. Chen Feng uses his knowledge of physics to make simple explosives and help them escape, earning the guerrillas' respect.
