とどく; 届く meaning in this sentence


と…とても信じられん…こ…この聖域にまでパワーがとどくなんて

Unbelievable! That the power would reach even this sanctuary...!

Looking for an in depth explanation of the usage of とどく; 届く here, because I've
read that it means reach as a movement verb that's synonymous with "arrive",
and what it means contextually for the subject here "パワー"




It should just mean 'to arrive/reach'.

I suppose the sentence comes from somewhere later in Dragon Ball (super saiyan
3?), where the power='気' is described as a kind of wave (like かめはめ **波** ).

The stronger/larger 気 is, the farther it is felt. So the sentence is saying
that the power is so strong to be felt even in the remotest place where the
speaker is.
