When surrounded by the Transcend Sect believers, Ash had thought he was in for a tough fight—although the believers posed no threat to him in his Host God Status, he couldn't just steal their Great Skill and go on a killing spree in their territory.
Silver Lamp might be shameless, but Ash still had his dignity!
However, to his surprise, the Transcend Sect believers didn't immediately attack but were willing to listen to their explanation.
Had it been any other sect, Ash might have thought they were scared, but the concept of fear didn't exist in the Transcend Sect; their decisions were the result of calculations made in their intelligence hub. If they had deemed Ash guilty of stealing the Great Skill, they would have kept him there, even if it meant losing all their believers.
Now that Silver Lamp had taken the Sonic Strum and fled, leaving behind the Transcendence Prison Technique on Ash, they would surely want to suppress Ash first before negotiating.
