Do parallel worlds really exist?
If all possibilities are brought together, different individuals collide directly.
Frustrated, wealthy, successful, beautiful, desperate, completely different selves.
Yi Shike, who was stuck at home and faced obstacles everywhere, was suddenly told that all versions of him in the parallel world would die at the age of 26. "I hope you can solve the mystery of death."
Forced by the mysterious organization, four different Yishike came together and traveled through different parallel worlds lurking around them.
The task is very simple, disguise yourself as various characters around "Yishike" and save yourself before the age of 26.
"Please survive." Yi Shike closed his eyes lying on the ground with his hands, "No matter what the cost."
Intention: Different selves meet together
