The Supreme Law from its first to third layers are just three stages oversimplified by Overlord Heiyuan for the sake of users who are beginners, afraid they might not understand them.
The fourth layer is where the real core lies.
And to construct a microcosm...
simulating even one Microcosm without condensing a True Spirit is almost beyond imagination.
But that's not the main point, the key is...
to simulate a Microcosm in a non-Star Realm environment.
Remember that any issues during the simulation of a universe may cause the collapse of the entire universe.
Such a collapse, like the collapse of one's divine life star, once it completely collapses, it will be thoroughly destroyed.
