At this moment in the Imperial Study Room, the most frightened was not the Heavenly Demon, nor Liu Qingqiu or Mu Yunxi, but the Leader of the Taiyin Sect.
He had not expected that Lu Chen would possess such an artifact capable of greatly suppressing Demonic Qi. Given this situation, even if they did not die, once they tried to escape, the Heavenly Demon would surely kill him.
It was he who had brought the Heavenly Demon to this perilous place, and the Heavenly Demon might well suspect that he was in league with Lu Chen.
Thinking of this, the face of the Leader of the Taiyin Sect turned deathly pale.
This won't do...
He must leave this accursed place, for once Lu Chen or the Heavenly Demon realized what was happening, he would have no place to bury his body!
The flag in Lu Chen's hand was too powerful in suppressing the Demonic Qi, that even the Heavenly Demon would likely be no match for him.
