How would the destructive might of the detonation of the 49 Great Overarching Dao Vessels be?
Jiang Ming finally witnessed it.
The intensity of such power shocked him. There was even a sense of despair that loomed over his heart. If it wasn't for the privilege of consuming points as the group admin of the Supreme Pagoda chat group, he wouldn't have done such a thing and would instead have fled long ago.
As for the waste of Dao vessels?
They were merely some Great Overarching Dao Vessels, not considered to be of great expense to his net-worth.
Since Jiang Ming began cultivating, he had barely done anything and would try to avoid them whenever he could.
As for the battles in the Supreme Pagoda? They were just to pass through the levels after all.
As for reality? He also wanted to keep participating in great battles and completely releasing himself from his own shackles. However, there were very few occasions that allowed him to.
