"An embankment stretching a thousand miles could be destroyed by an ant hole..."
"Even the strongest fortress could be dismantled from within..."
"One could only say that there were capable people among these Four Great Evil Spirits..."
After seeing through the Four Great Evil Spirits' intentions, Li Yun could not help but marvel inwardly.
Was the White Emperor Inner City strong?
Without question, it was absolutely formidable.
The Array Dao and Seals that formed the White Emperor Inner City were unquestionably the most extraordinary Li Yun had ever seen. To this day, he had yet to encounter any place whose Array Dao and Seals were more profound and mysterious than those within the White Emperor Inner City.
To any force outside, such a White Emperor City was a super fortress that could not be breached through a frontal assault.
That was precisely why the Four Great Evil Spirits had come up with this method: first sending people in secretly, then establishing Altars to draw in the strongest powers of the Four Great Evil Spirits, launching an internal assault.
This method could be called fatal.
