"The Start of Axelle's Plan"
Axelle always knew what he wanted by creating a domain. He had already comprehended the tricks and the way to blow up the abyss tunnel without affecting the main world.
The abyss tunnel was in the fourth void, which means it was in the same space as many summoned domain clones.
The fourth void was bigger than the first three layers of void because the first three layers of the void were all locked with owners, which means that space was like a densely packed honeycomb with its own space inside the honeycomb.
On the contrary, the fourth layer of the void was similar to the space crack full of real domains, dimensions, and various worlds.
The space crack was like the universe that contained tons of small worlds or big worlds and inside those worlds, if there were any concepts of plants, solar system, and such, then, there would also be countless galaxies and universes inside that 'world'.
