That meant he needed flying pets to do so, to move warriors enough to gather wood, and make them return here to resupply the exhausted reserves.
"How can I do that?" he muttered to himself, thinking about how to solve this dilemma. He didn't lack warriors, and currently he could spare to send thousands of them away, but the only problem lied in how to move them there!
"Sigh, the only solution is to use Birdy and make him move them on many trips, risking attracting the attention of others," he sighed, as he had no other option here.
All the monsters appeared so far were ground based monsters, not a single flying one showed its ugly face yet. And so, he was lacking in the flying mighty power of pets, and currently he had to act with what he had in hand.
