1. Beyond death.

In the last moments, just before his death, a strange entity called system 003 offered Zaccariah a deal.

As long as he completed missions in other worlds, he could return to his original world and in addition, the system could strengthen his body, letting him live a painless life.

The deal was made. Zaccariah started transmigrating to different worlds. However, there was an unexpected thing that would make him hesitate to turn back home.

He fell in love with another soul, who accompanied him through this journey. Would he be able to discover the real identity of his immortal lover, who kept following him in each and every world?
