Time and Space Observer: the Counterattack of the Abandoned Concubine in the Cold Palace

"99% Of the historical deviation value has been detected, and the host needs to perform correction tasks immediately." The dying girl Wen Ci was selected by a mysterious system and traveled to the ancient cold palace to become an unpopular talent. Her mission was to give Concubine Xian, who was supposed to have been poisoned, a "reasonable death", but during the investigation she discovered that Concubine Xian was actually a modern female forensic doctor whose fate had been tampered with by a time traveler. [Observer candidate has been activated] The Bronze Key awakens in the secret passage of the Cold Palace, and a warning pops up on the system interface: "There are 108 traces of tampering in the current world." Only then did Wen Ci understand that the so-called "revision of history" was nothing more than a human experiment by higher civilizations. The key figures in each world have despair and obsession that can be exchanged for "time and space crystals". And the key she carries can actually unlock the truth about the reincarnation of civilization—— When the murderer in the modern suspense world hands over a blood-stained pocket watch, when the Zerg princess takes off her disguise mask on the interstellar battlefield, when the sword fairy triggers the Nine Heavens Thunder Tribulation for her... The observer's mission is to witness all possibilities. ——When the bell of the seventy-second reincarnation rings, she will use her flesh and blood as a blade to expose this lie that has lasted for thousands of years.
