Zhou Jue deleted a scam text and got himself an ancestor.
The System bound itself to him, making him the customer service agent for old ancestors stuck in the mortal world: Du Fu, Li Bai, He Shen, and Yue Fei lined up to possess him and send messages to the dead.
It wasn't until Du Fu got stuck at "May there be a grand mansion with ten thousand rooms," then grumbled, "Someone changed the line that comes after," that Zhou Jue began to catch on. Someone was feeding the dead altered memories to "correct history," scrubbing away anything unpleasant.
He led a group of old ancestors from street stalls to livestreams, reading the deleted truths back word by word.
Want him to forget? Not a chance.
