Li Yao had devised a chain of plans, not too sophisticated, but more than enough to deal with these somewhat dim-witted Ogres.
Normally, the Ogres' defenses wouldn't have been this lax, but the matter with the Devil Tyrannosaurus had left their defense relatively thin.
Next, Li Yao located the position of the language totem he wanted to learn and lured out some of the Ogres.
Then he sneaked into the granaries, setting fire to the Ogre's stored food but not entirely, leaving them with the hope of salvaging their supplies.
However, the real kicker was the explosives that he'd already planted. Li Yao was a master of engineering in his previous life, so he was quite familiar with such things. Crafting an explosive device was child's play for him.
It's just that he found it too tedious to make one himself since an arrow would be enough to set it off.
