Before the Palace Lord of the Leviathan Palace left, he made sure that Ling Chen and Dark Primordial Shura Gods were well accommodated.
At the same time, he also warned the Supreme Elders not to antagonize Ling Chen, especially Supreme Elder Han.
Even though he previously listened to his orders to back off as he stated that he wasn't Ling Chen's opponent, he could tell that Supreme Elder Han was not convinced.
However, this wasn't the only thing that the Leviathan Palace Lord was worried about.
He was also worried that some of the Supreme Elders would be blinded by greed and made a move on Ling Chen because of the shard of the Dimensional Spatial Gateway key in his hand.
One has to understand, the Leviathan Palace only had three shards with them. As such, only three of them could leave this prison.
Obviously, as the leader and also the most powerful expert in the Leviathan Palace, the Palace Lord would have one ticket.
