In the middle of the 22nd century, humans achieved the immortality of memory through the "Meme-Stream" technology. As long as you are willing, all your life memories can be accurately uploaded to the cloud database for future generations to admire and even "experience". This technology is hailed as the greatest monument of human civilization.
However, at the moment when the great scientist Dr. Isaac Zhou, the founder of memory flow technology, passed away, a strange thing happened that subverted the cognitive system of the entire era: his memory backup stored in the central database of "Yggdrasil", the most critical and core section of it - the memory about his breakthrough research in his later years, was not deleted or damaged, but showed an unprecedented and absolute "blank".
It was as if it had been dug out precisely by the universe itself with an invisible scalpel, leaving no trace, no data redundancy, and a complete violation of the law of conservation of information.
In order to investigate this "impossible theft", **Ling Cen (Protagonist 1)**, a "cognitive detective" who behaves erratically and insists on using "outdated" simulation analysis methods, was secretly summoned. His only partner is Dr. Zhou's most proud disciple and the top maintenance engineer of the Yiliu system-**Su Wanying (Protagonist 2)**. One is an "archaeologist" who uses intuition and logic to look for ghosts in the ruins of data, and the other is an "architect" who firmly believes that data and code can explain everything.
