The surrounding cities were constantly making moves, but Du You didn't mind, as he had long been prepared for this.
The underground world was the first to pave the way, as there was no alliance formed there, and the place was desolate. Many cities didn't even know that a mighty Life Empire was growing right beside them.
After all, they could see very little, at most thinking the surrounding areas were unchanged, or that there were a few more Cities of the Dead.
With more cities, there were more enemies, but there were also more enemies of the enemies, which would instead make oneself more stable. This was their thinking, and thus no one considered too much.
So after expanding underground, they were eradicated immediately. Du You promptly controlled the passage to the surface, cutting off possible communication. Then, some people infiltrated to the surface through the passage.
In the surface world, they infiltrated into those City Alliances to gather intelligence.
