"Swallowing Domain" 

Axelle's domain grew bigger and bigger until it not only covered the whole floor but slowly covered the whole building, and soon, it expanded to the entire island! 

Of course, people could not see this scene with their naked eyes unless they were domain masters. 

However, this domain did 'overlap' with the space of the whole island in this world, so it directly covered the joint domain created by the domain masters. 

Axelle's domain had slowly penetrated into another space that was not in this world, but this kind of space was called the fourth space, which was where domains existed. 

Other worlds out there and dimensions out there might either occupy the same space and time or occupy a different space and time that needs people to travel through wormholes to visit. 

Now that Axelle's domain has expanded even to the sea area outside of the whole island, it was natural for this domain to collide with the joint domain.
