Extreme Cold Descends: My Contract Phone Lets Me Cut Through the Apocalypse with My Sword

[No Transmigration + No Rebirth + Multiple Heroines + Apocalypse + Superpowers + Sword Cultivation + Decisive and Ruthless] A sudden torrential downpour begins, and Chu Yuchuan receives a mysterious text: The extreme-cold apocalypse is coming. Master, please bind yourself with a drop of blood. When a two-dimensional beauty appears on his phone screen, he discovers he can use a food delivery app to buy hot meals and enjoy a temperature-controlled mansion in a world where temperatures have plunged to minus 80 degrees. Stranger still, a game called Sword Dao Supreme appears on his phone. It requires in-app purchases to unlock, but the sword-cultivation power he gains by spending 100,000 and beating the game works in the real world too. When looters come for his food, he cuts them down with a single sword strike! Become a simp? Not a chance! When his scheming ex-girlfriend calls to ask for food, he turns around and sells it to someone else for cash. Surrounded by superpowered foes? A thirty-meter sword aura will teach them a lesson! The major factions threaten him? For a Sword Immortal with an endless supply of goods, the apocalypse is a true paradise! Their threats seem so childish and ridiculous!
