Liu Zhi had never imagined that he would sell the so-called Space-Cutting Fingertip only fifteen years later.
Over those fifteen years, Liu Zhi upgraded his Demiplane into a plane and severed its dependence on the Rogar'a Plane, making it an independent plane in the void.
Liu Zhi named the plane the Id Plane, thereby accepting the lost family name of Sandru Id.
At the same time, Liu Zhi also acknowledged that the plane's central feature, the Underworld Ecosystem, had come from the Id Family.

In the ninth year after the Demiplane began upgrading, Liu Zhi established his first full-strength Hero Legion. At last, he had a complete legion.
