Tysm for the link, mad respect to you, my guy!

After rereading the suggested title and website the other generous users gave, I have an tickling feeling it might be this one (for this site)
https://www.mangago.me/read-manga/the_doomsday_ruthless_man_hoarding_trillions_of_supplies_at_the_beginning/
Setting: Korea
MC: Male OP(I think)
Apocalyptic Type: Intense Heat to the point where venturing outside is neared impossible..(skin would melt)
Story: MC awakens power ( I think)
MC owns building where it is cool and safe from the heat.
However the rich attempted making a money scheme for letting people stay shelter in their own building. But when they saw MC's building, they got envious(?)
Kinda vague, but I'd appreciate any help!
