The car circled down the track slowly, descending deeper and deeper, the air around them seemingly growing cooler.
Cheng Ye couldn't help but speculate, could Happiness City have carved out a gigantic underground space similar to a cavern?

As the vehicle slowly drove into the entrance, the coating on the window instantly vanished, revealing a new, expansive space before their eyes.
The underground space, originally imagined to be dark and oppressive, turned out to be at least fifty meters high.
The luminescent panels on the dome flickered lightly, leaving only a faint dark blue halo, perfectly replicating the serene ambiance of nightfall outside, with scattered points of simulated starlight, momentarily making one forget they were underground.
Looking to the sides, the scale of this space exceeded expectations, far grander than imagined.
