Lin Li's mind was raging with strategies as he confronted the high priest. He was trying to think of a way to counter Poer's attacks. Of course, instead of a confrontation, it was more accurate to say that he was trying his best to bear Poer's beating. He knew that he would be doomed if he were to abandon his resistance against those attacks.
Lin Li definitely had a lot of powerful trump cards, which included the Lord of Nightmares and the Lord Devourer that were sealed in his Summoning Lamp, as well as Xiao Hua that was living in his Dream Garden Ring. It was they who gave Lin Li the confidence to agree to Edmund's invitation to continue this exploration.
However, he knew that these trump cards would only be effective at the Sanctuary-realm. If he were to have a conflict with the Gilded Kingdom, these cards would definitely help the Tower of Dusk gain the upper hand. These trump cards would not suffice when his opponent was half a step from becoming a divine.
