The cost of wrong upbringing (2)

"I thought that high level of Aura of Gloom only caused people to get infected by Glooms and Aura," said Luo Huian as she looked at the child in front of her. 

As she stared at the smiling child in front of her, it was simply impossible for her to even imagine that this child would grow up and become a killer.

"Well they indeed get infected by Glooms and Hollows but it is not necessary that the Glooms would manifest itself as soon as it takes a host, you see?" Xiao Bai explained. "From what I learned about this world, Glooms and Hollows can take years to show themselves. There is no determined time for it to happen. It can take place at any second." 

"Killers are never born, Huian," Xiao Hei sighed. "Well some are just rotten from birth but their upbringing also makes and plays a very important part in it."
