Wang Wei did not care about the fate of the people in this world. Although that sounded very cruel, however, recent events have taught him that the world is unfair, and few people or things can control their fate.
In the current situation, there is little he could do. His strength was not enough to fight an entire Emperor Lineage. As for involving his sect in this conflict to intervene in the current chess game?
He would not place them in such a dangerous situation. The Dao Opening Sect was far away, so, fighting with the Unspoken Sect–which has a home advantage–will be extremely difficult, especially when the benefit was not worth it in the long run.
Although the Begining Profound Continent is a pure energy cultivation system, meaning that the Great Emperors and Dao Ancestors of their sect are generally weaker, there is still the possibility that some heaven-defying genius will appear and become an Eternal Emperor.
