MCB radius and 40 meters deepness , thats into ''Asteroid impact''territory , Frieren isn´t matching that.
also i love how they thing ''she can resist temperatures that are near to absolute 0 because she at some point resisted some enviroment cold''
What's ironic is that's not how Idea Blood works...
Despite Nasu stated how Hot or Cold Vlov's Heat and Cold are, what makes Idea Blood/Principle so terrifying is that it's basically the equivalent of Divinity for Divine Spirits but with no regard to the Planet being able to regulate it.

The Twenty-seven Dead Apostle Ancestors/Remake
The Twenty-seven Dead Apostle Ancestors (死徒二十七祖, Shito Nijūnanaso?) are a grouping of twenty-seven Rank IX Dead Apostles. The very apex of all Dead Apostles, the title represents their way of being.[1] The Dead Apostle Ancestors have existed for three thousand years. They are primarily...
Idea Blood: Hemonomic Principle (原理血戒(イデアブラッド), Genri Kekkai(Ideaburaddo)?) is the blood that makes an Ancestor an Ancestor, said to be the "Mandate (戒め, Imashime?) of the Original Cause (大本, Ōmoto?, "Root/Origin") engraved upon their soul". A "Truth" that they have each attained, the worldview that makes up the foundation of their "thirst". A Singularity (特異点, Tokuiten?) that paints over the planet's physical laws just by circulating blood. Wherever an Ancestor asserts their Idea Blood becomes their territory, subject to the influence of their Principle's curse. Arcueid compares it to a "crown" as the inheritance of the Idea Blood will raise the inheritor to a Rank IX Ancestor regardless of their original rank.[25][26] It is also possible for new Idea Bloods to be created, as magi who became Dead Apostles and then later became Dead Apostle Ancestors are those who created their own Idea Blood through a vast amount of time and research.[26]
It's why Arcueid had to go to such "extremes" in needing to block both Vlov's Heat and Cold and why it's insanely impressive Ciel can just tank it because "lel Magic Resistance"(Yeah, Frieren can match in scope the same person who can actually withstand TWO Idea Blood unlike Vlov with just one and can use that as a byproduct of using the Magical Theoretical equivalent of Excalibur twice). But back to the point, Frieren wouldn't be able to block anything from a Idea Blood/Principle in the first place and saying otherwise... is just dumb.
