Kingdom of the Dark Blue Travel

Xia Yuyang unexpectedly received a death invitation from his deceased grandfather. After experiencing seventeen deaths, he arrived at the Wheel of Reincarnation in Hell in hopes of rebirth. There, he learned that the only way to be reborn was to travel to various worlds, fulfill the regrets of the clients, and complete the tasks assigned by the system to earn points. His journeys through different worlds and the lives of various clients immersed him in these illusory realities. He gradually forgot his own identity. Who was he? What was his wish? In fact, all of this was a long-plotted return!
