When Song Shuhang delved into the concept of "shared reality illusion," his mind easily embraced the idea.
"Isn't it essentially sharing a genuine illusion?" In this era, regardless of the reliability of anything, the prevailing trend was to explore the concept of "sharing." It wasn't that big a deal.
In today's world, whether it was a house, a car, a bicycle, a computer, or a smartphone, nothing was exempt from sharing. Even relationships between boyfriends and girlfriends were venturing into sharing services. Whether it was reliable or not, giving sharing a try seemed like the right way to go.
The small illusory reality that the Overlord Hound Xie Wang had conjured was shared from a more formidable Xie Wang.
As for the even mightier Xie Wang's true form, it wasn't even within the confines of Earth's space. How he managed to "share" his genuine illusion remained a mystery.
