Originally, in Hu Fei's view, Zhou Tian had an extraordinary 'talent', and relying on his early rise, Hu Fei determined quite early that Zhou Tian had a promising future. It was precisely because he knew Zhou Tian's future was significant that Hu Fei bestowed Zhou Tian with a treasure like the Teleportation Ring, despite not having much affection towards him.
Probably Zhou Tian's development later somewhat exceeded Hu Fei's expectations! Surprisingly, when most of the monsters were trapped in a certain realm for many years without any breakthroughs, Zhou Tian kept surpassing his own limits and eventually became a boss of King Level strength.
Also, because Zhou Tian's rise was so rapid and given his limitless potential, Hu Fei, believing that Zhou Tian could recreate the Beastman Empire, committed the act of kinslaying.
What Hu Fei didn't expect was that after Zhou Tian's power expanded to its limit and stabilized for a few years, he became content in embracing his pleasures.
