In the near future, a giant company called "Tianqiong Technology" has released a revolutionary brain-computer interface device "Lingxi", which allows people to directly upload, download and share memories and skills. However, when a top neuroscientist dies mysteriously after completing a critical upload, his apprentice, Lin Jian, a talented programmer who has sealed part of his memory due to trauma, is forced into the whirlpool. She discovered that "Lingxi" is not a staircase to heaven, but a carefully designed cage of consciousness. Uploaders will become "digital slaves" in the virtual world, while downloaders may lose themselves in reality. Lin Jian must search for the truth in the maze of his own memory and cooperate with the mysterious rival "Guardian" to uncover the ultimate secret that the founder of "Sky Vault" has hidden for centuries before the global conspiracy completely breaks out.
