Everything Must Be Reversed

In the quiet place of the starry sky, a spaceship flew across the starry sky and flew into a dark and closed planet. Humanoids float out of the spaceship and into the dark forest. He came to this place of death in search of ancient ruins. Stroking the stone pillars with square runes, he groped forward, and after a while, he entered an ancient tomb. There was a faint blue light emitting from the cave, and he walked deeper. There was a dark metal door at the end. The humanoid creature stroked the texture on the door, feeling the unevenness of the runes with his fingertips, and the door opened silently. Behind the door was a metal hall that could not be seen at a glance. He walked towards the deep darkness. The hall contained the bones of many strange beasts made of unknown metals and minerals. Going deeper, they are all still corpses, but they are perfectly preserved, as if they died yesterday, immortal and dazzling. How many stars are passing by, their gazes remain the same, which is chilling. The humanoid creature looked around and caught a glimpse of a black square box glowing with scarlet light behind the blue tassel at the top, with the word "Apocalypse" engraved on it. The humanoid creature was overjoyed and flew up to hold it. He felt a powerful wave coming from the box. He held the box hard and smashed it into pieces. In an instant, scarlet light and shadow shimmered around his whole body, and a low hoarse voice echoed in his head. "Certification passed, welcome to my world." The humanoid creature's pupils shrank suddenly, and countless pictures, sounds, and words flooded into his consciousness, and various past events of an ancient civilization flashed in his mind. Like a history of something... No! This is one person's memory!
