Stencil’s Long-term Advantage
Stencil focused on Minhua's Constellation. Even though the Constellation seemed to be one person, it wasn't.
It consisted of a set of people that had performed almost similar feats and were recognised by the masses to be similar. Their collective consciousness data was extracted from the world and transformed into a Constellation that now resided within the Tower of Accomplishment.
Thanks to World War Three, plenty of heroes emerged, some known, some unknown. The data of countless such similar ones was enough for Stencil to create almost seventy Constellations, which was more than enough for this world to run and develop for a few thousand years.
Moreover, the same setup existed in the tower too. As people of renown die within the tower, they too might become a Constellation one day. Stencil had established all the necessary rules for that too.
