With just a glance, Duan Ling Tian could easily guess the identity of the middle-aged who was staring at him with a hostile gaze. It was the Vice Mansion Master of Mystical Sky Mansion, Zhao Deng. He was also Zhao Ji's father.
Duan Ling Tian could easily guess his identity because this man's eyes resembled Zhao Ji's eyes up to 60 to 70%. It was impossible for him not to be able to identify this person. Now that he knew this person's identity, he no longer found the hostile gaze strange.
He and Zhao Ji were as incompatible as water and fire. It was only natural for Zhao Deng to regard him as an eyesore.
As for the other two middle-aged men, Duan Ling Tian could also guess their identities. They must be the two other External Affairs Vice Mansion Masters other than Zhao Deng.
There was a total of nine Vice Mansion Masters in the Mystical Sky Mansion.
