Da Song: Countdown to My Life

Shen Ran, a senior high school student, physically traveled to Runzhou in the Northern Song Dynasty during an experiment.

He thought he was teaching her how to survive. Little did he know that she was becoming his only meaning in this world. In modern times, he can't get a word of recognition even though he tries his best.

But the countdown never stops. And the system has an iron law that he never dares to touch: if the heart beats, it will die faster. When the end of the fifteen days came, she responded to all his teachings in the same way he taught her. He caught it with a smile...
