Once intelligence was obtained and the Undead Scourge could send forces over, Ye Qian would immediately deploy thousands to tens of thousands of Skeletons and select a small number of commanders.
After the initial few days of expansion, the Skeleton forces would often have already doubled in number. Then the main army would begin slaughtering the various alien races.
The strategy along the way was simple: send people to persuade them to surrender.
Those who refused to surrender were killed, while those who surrendered obediently were brought under their rule.
A war lasted no more than a few months at most.
Exponential growth was simply too terrifying.
Most worlds did not even have enough land for the undead to kill across. Moreover, Ye Qian specifically preyed on the weak. In many of these worlds, the strongest individuals were only at the Black Iron Rank, and quite a few did not even have Black Iron Rank fighters.
She had even considered unleashing a disaster in a technological world next time.
This ultra-low-cost disaster-launching model had allowed her to attack sixty-five low-level worlds with Skeletons. Of those, forty-five used new armies pulled from this New World invaded by the Demon Lord just two days ago.
So when she learned that the enemy had as many as ten thousand Mithril-level fighters, Ye Qian was not worried at all.
The undead had their own weaknesses. For example, they were badly countered by the power of holy light. But her armies from other systems were also developing at high speed; they simply were not growing as quickly as the undead.
Whether in army deployment capacity or growth rate, the two sides were not even on the same level. The reason she could not defeat the enemy was simply that her army's quality was insufficient.
