The Eighteen Levels of Hell: Lying is Forbidden Here

Diwu Zeyi drew his Liar-Slayer, also placing it in front of himself, and then lit a Cigarette.

Doing a final sorting out:

The Four-Dimensional Aliens symbolize Qiu Yinong.

The human world was covered by a layer of virtual world by the high tech of the Four-Dimensional Aliens, leading to humans' consciousness being in the virtual world, while their bodies did hard labor in the real world.

What this corresponds to is: Diwu Zeyi and Chen Ran's bodies are in the real world, while their consciousness is in the virtual world.

The virtual world is a product manufactured by the Four-Dimensional Aliens.

Then, the scene here is manufactured by Qiu Yinong's Wheel of Time.

Deducing up to here.

Diwu Zeyi widened his eyes.
