Lin Feng only had ten days. He would not charge into territory of the Celestial Devils without thinking and slowly search for those Celestial Devils. Otherwise, ten days would not be enough to search for traces of the Celestial Devils.
Lin Feng had to find the exact location first, and come up with a precise plan.
Hence, Lin Feng found some Supremacies who knew the area where the Celestial Devils were very well, and asked them about the internal situation of the Celestial Devils. Apart from the Celestial Devil World, where else could a large number of Celestial Devils be found?
Those Supremacies did not disappoint Lin Feng.
According to the intelligence they received, there were actually many Celestial Devil Worlds, far more than one. The elders of the Epoch Alliance went to the largest Celestial Devil World to besiege it. Many top-notch Celestial Devils were in that Celestial Devil World.
