Upon learning the whereabouts of a large number of Mechanical God Cult Believers, Lind took action immediately.
To prevent Undead from leaking information and attracting competitors, hence adding "uncertainty" to the future, Lind promptly estimated the scale of the war.
Ever since acquiring Undead, his style of warfare hasn't changed; it basically consists of going all-in with Undead.
After all, Undead are cheap to use, simply mobilizing a human wave tactic with sheer numbers, and Lind doesn't need to care about the specifics of operations; the Undead will play their part.
But not this time.
"We need a detailed map, including the surrounding geographical environment, and any potential strong entities nearby."
This is a vastly consequential war.
The terrain of Misty Rain City is complex, and every Ring Knight is very powerful, not to mention they all guard something sealed underground.
