Honkai Impact 3Rd: Echoes

Warning: If you discover that you can walk through walls, get away from that wall immediately! The mountain city’s “walls eat people” urban legend has been around for eighty years. Department 213 has investigated it for a lifetime without finding an answer. Then ordinary man Shen Yu passes right through a wall, and careful investigation finally uncovers the shocking truth behind it: this isn’t a paranormal incident at all, but a living experiment spanning countless dimensions. Some people want to return to the past to make up for their regrets, but cross the line set by a higher-dimensional civilization and are hunted across dimensions. Others dig deep into dimensional theory, only to discover that they, like this world, are nothing but a fleeting phenomenon. Just as everyone thinks they have no choice but to keep ascending to higher dimensions, a terrifying truth explodes onto the scene: dimensions have no upper limit, and every ascent is just another layer in an endless nesting doll! So who created the entire dimensional world? What is its purpose? How many dimensions does the world people live in have? And how many dimensions are humans themselves? How do dimensional civilizations evolve, layer by layer?
