Arknights' Dad Chen, Returned from Star Rail

To make a long story short, Chen Zhaoxue, former son-in-law of the Great Yan royal family, former Terra's undisputed number-one fall guy, and a memory-walker of the railways, has somehow been reborn yet again. He was reborn, all right, but there was something deeply off about this Arknights timeline. Facing a white-haired blood demon who showed up with a hidden identity: "Terra's advanced enough to colonize other planets? What's Talos-II? What do you mean people in your era spent every day hoping a Catastrophe would come?" Meeting a purple-haired dragon girl with the same face as him: "Wait, what do you mean you're the future Chen Huiye, and you came back through time to make amends for your mistakes? Since when does Terra have that kind of technology?" Looking through ancient books in the library: "Why are all the Sui fragments women? Hmm, though I guess that has nothing to do with me... Miss Accomplice, why are you looking at me like that?" Sui said nothing, only bringing calamity upon the world. P.S. Yan Jing is dead, Wen Yue is dead, Wei Yanwu is dead. Check the record.
