Do Whatever You Want in the Last Days, but You Are Respected as the Savior

(Apocalypse + time travel + plunder system + building defense + mecha + crazy shopping + decisive killing) "Oh, are you sent by God to save us?" No, no, no, have you misunderstood something? I am just trying to plunder. Wang Tianyu traveled through the apocalypse and awakened the plundering system. In his previous life, he was timid and died of staying up late working, so he will change his way of living in this life. "Potatoes as big as basketballs? Buy them!" "Wag spinach that grows once a day? Buy it!" "An air compression gun that doesn't consume bullets? Buy it!" "A mecha more powerful than Iron Man?? Buy it!" In this apocalyptic world, plundering is the way to survive.
