Tang Shaoyang had guessed that these two factions wanted to make peace with him once they tried to meet him after their loss. With how they reacted Tang Shaoyang guessed right, and it seemed they tried to make the Tang Empire's situation against Nirvana to press for peace without giving Tang Shaoyang anything.
'With how they try to resolve our issue after losing to me, it seems the Ancient Rank Dimensional has more worth than I thought. If I want to get something out of them, I can't ask for outrageous compensation. At least, it should not be worth more than the access to the Dimensional Tower.'
The Federation of Allurion and the Giteron Dynasty could just pull out their force off the Dimensional Tower. There was no need for them to talk their issue out. The fact they tried to talk it out, it clear that even an Ancient Dimensional Tower was worth more than he thought for the two big factions.
