A light-purple petal rapidly expanded in Meng Chuan's eyes; it expanded by billions of times. He saw a particle space, a particle core, and objects of varying sizes inside the particle core. He then continued zooming in by a billions of times.

Whoosh.

Everything became countless tiny spheres.

These sphere-like objects were extremely tiny. They were the smallest objects in the entire River of Spacetime.
