Now sorry for being the need here but that is "only" two tsar bombs output for example to have a shot at destroying Mt Everest you need around 550 tsar bombs detonating at once to have a shot at destroying it

mc and jack are already doing more damage than two tsar bombs book 4 mc will be country buster and remember that's with the chi making the planet more durable so it isn't like our world a country buster is like a continent Buster in a world without chi so yeah nukes are kind of useless already radiaton is the only thing that can be troublesome for current jack and mc and that too is just a soul check.
