"Mr. Bai, if someone has been injected with Reagent No. 6, is there any other way to undo its effects?" Ling Chen asked.
Bai Zhangqiu shook his head and said, "In theory, you can inject Reagent No. 6 again and reprogram the subject's brain. But we've done related experiments. The results show that if a subject receives two injections of Reagent No. 6, the brain won't be able to handle the load, it will collapse outright and they'll become a vegetative patient. There are still a few such subjects lying in the ward of the lab. It's been years, and there isn't the slightest sign of waking up."
"So there's not even a shred of hope?"
"More or less. But not everything is absolute. Although Reagent No. 6 can reprogram the brain, no one can guarantee that its effects will last forever. It's possible that the brain's original real memories will resurface and replace the written memories. That kind of thing could happen."
