Please Keep Your Heart Beating in This World of Survivor's Paradox

Firefighter Lin Jin once left his fire career because of marriage, but ended up with a tired life and full of disappointment. On the day he left home, he received a strange mirror fragment from his ex-girlfriend Shen Mo. The mirror inexplicably reflected the city hanging upside down. At night, he was chasing a strange fire. As soon as he arrived at the scene, his heart stopped abnormally. Then he saw another version of himself in the mirror fragment, wearing a firefighting suit and shouting anxiously in the flames. When he opened his eyes again, he had traveled to the mirror world: everyone here was silent and only relied on the sound of heartbeats to communicate. A slow heartbeat will lead to a weakening of consciousness until it disappears; a stopped heartbeat will completely assimilate the world into a background sculpture. The most terrifying thing was that Lin Jin found that his heart began to stop frequently. He must find silence before each heartbeat stops. This is the only existence that can speed up his pulse, so that he can have a chance to leave the strange world. Among the mirror fragments, Silence pointed out in horror the limbs that were gradually becoming transparent behind him - there was not much time left.
