According to his citizens' info, these cities had roughly around 4 million population, mainly players. Each city had 4 strong NPCs. Ibro took nearly 6 hours to summon over 10 million skeletons.
These skeletons were advanced class skeletons. Ibro didn't stop his technique, but that army started to move. 100 death knights helped with 100 cultivators moved with this army.
Ibro had revised the plan of assault with them. This time, he came well prepared. He had huge amounts of catapults and siege ladders, so he didn't need to use his previous risky maneuver.
Ibro then continued to summon skeletons. Every 6 hours, a new army was formed and started to move towards its goal. Ibro took nearly 3 days to completely form 10 armies.
During this period, 8 cities had already fallen in his grip. Each time a city would fall, Erond moved to this city and organized the matters there.
