Can this be considered a feat?

[Berhann]

The push and pull between Yeon-woo and the Crawling Chaos began to make the universe bend around them. The dimensions of the physical world began to collapse as though the universe were on the verge of destruction. A bent space of the fourth dimension appeared.

Crack. It was a singularity that swallowed all matter, anti-matter, time, and space, creating an ergosphere bounded by an event horizon

And then

As they did, the gravitational singularity widened, and the dimension began to collapse faster than the speed of light, creating a black hole.

So is this a feat, what tier would it be?
(Btw they are fighting out of the universe where the creation(expanding of universe, big bang) hasn’t arrived yet)

Seems to me they are heavily affecting the entire continuum, eventually destroying it as a side effect, so this looks like low 2-C to me

 

[It_is_i_wyatt]

yeah I think low 2-C

Anyone else want to weigh in on this question?
