Liu Yang recounted what had happened on Blue Star several years ago.
"It was a very strange urban legend. It kept borrowing things from you, starting with food and drink and eventually moving on to borrowing your life."
"One step at a time."
"There was no way to get rid of it, nor any way to fight it."
"No matter where you went, it followed you like a shadow, appearing beside you at a fixed time."
"You didn't go home."
"No problem."
"It would walk over from the street to ask you for something."
"You beat it to death."
"That worked too."
"But tonight would still count as having completed the borrowing. Tomorrow, it would move on to the next step."
"And it could spread like a virus."
"Some of the people it killed would turn into new versions of it, appearing in other residential areas nearby to borrow things from other people."
"That was why almost everyone on that block eventually died."
"Even those who escaped the Red House."
"As long as the Bad Neighbor appeared in the apartment building, you would be marked even if it hadn't come for you yet."
"It was only a matter of dying sooner or later."
"The Red House was on the verge of collapse, and many people escaped."
"In the end, someone told others what had happened inside. The story spread from one person to ten, then from ten to a hundred, until everyone knew."
"But by then, it was already too late."
"In the end, across five or six apartment buildings and seven or eight hundred people, only a handful survived."
"That guy named Bruce was one of them."
"Before the apartment buildings became infected, he personally led a team outside to investigate an escape route."
"He avoided the invasion."
