A master of the Core Formation Stage wouldn't waste their time trying to capture a Foundation Establishment Stage demon beast. It seems there's only one possibility: that Core Formation Stage master is the Crimson Wing Golden Tiger that came out of the Sub-Thunder Element Dimension Realm with Ye Haochuan.
When they initially exited the Sub-Thunder Element Dimension Realm, the Crimson Wing Golden Tiger mentioned smelling his brother's scent and went straight to find him. During this period, Ye Haochuan had been busy with many matters and hadn't paid much attention.
It now appears that the Crimson Wing Golden Tiger likely arrived at the Human Sect headquarters back then but sensed the presence of a Core Formation Stage master overseeing it and chose to remain quiet until now.
