Xi Qianxue candidly shared her own information, which Du You realized was immensely helpful for performing tasks in the Other World. He also gained a certain understanding of the normal monster-killing process in the Other World.
However, he thought all the scheming was too much and somewhat meaningless. To Du You, being in the Other World is simply about fighting the battles you can win and retreating from those you cannot. It's that simple. Why complicate it with all the scheming?
After all, the main reason for Du You to come to this Other World is to enhance his power; all other factors barely mattered to him. If he still had to scheme after gaining power, it would be rather unpleasant. However, everyone has their ways. Du You couldn't really argue.
Since it's an advanced task, Du You still planned to observe how others complete such a task to glean some experiences. Who knows, he might learn something new.
