This Earthling was, naturally, Wang Yi.
At that moment, Wang Yi drifted through the streets and alleys until he arrived at the underground laboratory in Fuxi's home.
Fuxi looked at Wang Yi and said apologetically,
"I'm sorry. I implanted the system in you without your consent."
"In fact, it seems you became one of my test subjects. I'm sorry."
Wang Yi was silent for a moment.
"I got more from the system than it got from me. I should be thanking you."
Fuxi said to Wang Yi, "Actually, I only recently discovered that the system has a defect. It causes mild side effects in the human body."
"If it's implanted for more than fifteen years, the side effects will build up to a certain point and eventually take effect, causing a series of serious consequences. In mild cases, the brain will shut down—in your Earthlings' terms, cerebral palsy. In severe cases, the person will die suddenly."
"That's why I apologized to you."
"It's been fourteen years since you got the system implanted, hasn't it..."
Wang Yi interrupted him. "Wait. You said the system was only implanted in my body a year ago, but I've had it for fourteen years!"
Fuxi explained, "I forgot to explain. When I implant a system across space, it distorts time to a certain extent. So one year here is equivalent to fifteen years on Earth."
Then Fuxi continued,
"So before it reaches fifteen years, I need to take the system back and implant a micro-dose of medicine in your body."
"This micro-dose has no other purpose. It will simply eliminate the side effects in your body. It will keep working in your body over the long term, and no Earthly detection equipment will be able to detect it."
At this, Fuxi turned to Wang Yi
