In the endless world, a strange legend circulates: in a special little shop, by signing a contract with the shopkeeper, one can obtain everything they desire—powerful strength, countless riches, and knowledge from another world! But few know that this shop also possesses the power to change destiny, whether past, present, or future, or regardless of race or identity. When they are willing to gamble everything to change their fate, the door to this shop will open for them, and a new destiny will be born here! "Sign a contract with me, and then—transcend destiny!!" — Meanwhile, the shopkeeper, Lan Xing, is looking helplessly at his ever-growing deficit in his account book. He doesn't know when it started, but the number of girls in the shop seems to be increasing: twin oni maids, an elf girl who loves dolls, a cat-eared blade that transforms into a sword… 'The meal expenses have gone up again this month.' He only initially wanted to reciprocate a gentleman's kindness… (Also known as the Dimensional Aid Exchange, Dimensional Oddity Store, Dimensional Exchange…)

Fang Yan transmigrated to a crossover anime world. Looking at the familiar two-dimensional characters, he thought he had entered the world of a slice-of-life anime. But suddenly one day, Aki Tomoya died and turned into a vengeful ghost to come after him. At the critical moment, his system was also prematurely reactivated.

Defeating a Hydra agent only adds 0.2 contribution points? Looking at the 10 million contribution points required to unlock the Sun Disk, Lin Yuan fell silent. Rebuilding Shurima's glory, Hydra shedding a little blood—isn't that a bit much? When Thanos descended, he encountered the newly unlocked Mordekaiser; when the Time Bureau wanted to annihilate the timeline, they met the time assassin Ekko; when the Celestials descended, they encountered Aurelion Sol, the Star Forger; Lin Yuan thought: It's normal for a legitimate Shurima Empire to be full of talent, right? Those who offend Shurima, no matter how far away, will be punished!

Fairy Tail world: "Kimitsu, give me some healing!" Natsu, who had been beaten to the point of vomiting blood, shouted to the person behind him.

"Heal you? Impossible. You charged out the moment I applied the buff. How am I supposed to heal you? I'll have to rely on fatherly love."
