Yan Zhaoge's motto was that in doing great things, he had to have an audience. If there wasn't an audience, he would have to create one himself.
As that Copper Men Island Elder had said, with the situation back then urgent and chaotic, how would he have had the leisure to look for witnesses?
Yue Baoqi had been in charge of baiting Kang Jinyuan out. Out of safety considerations, she could leave after having completed that task. There was no need for her to remain there with that done.
Meanwhile, as Yan Zhaoge possessed the Heaven Spying Orb, he would naturally secretly record the entire process of him breaking of the Heavenly Fire Tribulation Thunder Formation.
When he flashed the Heaven Spying Orb, those of the Radiant Light Sect vaguely felt that something was wrong as some of them tried to move to obstruct him.
Dim Darkness Sect martial practitioners went forward to obstruct them.
