Jiansan Mengxin Airborne and Cursed Back, but the Savior

Li Xue traveled through time with the Jian San Yantian trumpet. There is a language barrier, no relatives, and skills are locked. Fortunately, the neighbor sister and brother next door are kind-hearted, and the temporary guardian is also a handsome guy. This kind of life with money, houses, internet and beautiful women can last another hundred years! (Ah, is this the resonance of social animals?) But isn't something quite right in this world? What about the peaceful and peaceful retirement life we promised? Why do you still have special powers? And one, two, and three of them all looked like they were about to die. Help, is the world about to be destroyed? ! I just want to be an "ordinary" person living an ordinary life and live happily with my friends. Why is it so difficult! Damn, useless adults, this desperate world still has to be saved by minors. (It's only when you're bragging that you think you're underage.) Pretending to be young and fake lolita × tsundere and sultry male protagonist (they are the same age after time travel, but they are in love with each other, maybe.) Demining: 1. The author has only watched anime, and his goal is to reverse various tragedies and save the people he wants to save. (Don't tell me whether the plot is broken or not, don't listen~) 2. Some settings may be different from the original work. Don't ask if you didn't understand the original work, just default to the private setting and lie flat. 3. Unorthodox Sword Three, traveling through the mutated version of Yantian, a half-dead system. 4. Omnivores, they are all written as fandoms just for the purpose of making fun of each other, feel free to make fun of them, but don't quarrel. OK? GO→ Purpose: Use the power of another world to rewrite the established tragedy
