Du You didn't use conventional military forces but secretly began gathering eighth-tier undead creatures.
These undead creatures were all created by Du You, and they completely obeyed orders, so there was no issue with secretly gathering them. This time, Du You brought out most of the undead creatures.
Including the newly created ones this time, the total has reached nearly three hundred.
The undead city lords elsewhere are just things put on display.
The undead created by Du You are not the same as the ordinary powerhouses of this world. Ordinary powerhouses can rely on city fortifications to enhance their strength, but the undead creatures created by Du You don't have this ability.
From the moment they were created, their strength was already developed to the utmost, and all their potential was squeezed by Du You. These undead creatures have no possibility of further development and cannot continue to improve.
