Preface

There is always something that will come to you through time. For example, recurring dreams, numbers that emerge inexplicably, and dark patterns engraved in consciousness. Lin Yuan thought it was an illusion until he met a fellow traveler and walked into the deserted old factory area on the outskirts of the city. There is a machine called the "Iron Curtain" hidden there, which hides the critical laws at the bottom of the world and the concealed memories of his childhood. He finds the truth but does not take away the secret; Touch the rules without trying to control them. He just quietly read a piece of history, gently closed the dust, turned around and returned to the human world. True seeing is not about changing the world; But let everything return to its original state.
