Scavenging the Post-Apocalyptic Wasteland: One Trash Card Lets Me Slay the Gods

In a parallel world, cracks appeared out of nowhere across Blue Star, and countless Void monsters invaded. Humanity fought desperately to hold them back! Su Yu, a high school student, unexpectedly awakened a supernatural ability that let him travel to the wasteland of Blue Star a thousand years in the future! At that time, human civilization had long since fallen. The once god-tier magic cards and supreme technologies were now nothing but rubbish nobody wanted! While his classmates were tearing their hair out over a single bronze magic card, Su Yu could spot flaws at a glance using future [blueprints], then turn around and improve them! [You found a damaged blueprint for the “Frostglass Dragon” card. By analyzing its future energy circuits, you had a sudden insight and created the “Ashen Frost Dragon,” uniting ice and fire and vastly increasing its power!] [You found a fragment of a future technology blueprint and brought it back to the present. It turned the Federation Academy of Science upside down and led to the creation of a groundbreaking source-energy core!] [You found the “Final Record” of a future civilization, glimpsed the truth behind humanity’s extinction, and obtained the only key to overturning fate!] Card-making prodigy Lin Wan'er: “Impossible! This card structure completely overturns all existing card-making theory! Su Yu, who are you?” Hot-blooded buddy Li Hao: “Holy crap! Brother Yu, this card of yours is insane! It’s even more awesome than high-martial cultivators! Count me in!” Federation Speaker: “This young man... no, this person is the last hope of human civilization! Give him everything he asks for, whatever the cost!” As the Void monsters reached humanity’s doorstep and people sank into despair, Su Yu slowly walked out of Dawn City and pulled out dozens of immortal god cards. “The power you’re so proud of is nothing but... rubbish I picked up on a whim.”
