One thing...

"Invade planet Nihari...and take over its resources?" Robin muttered in a low voice

Robin hadn't thought about this even for a moment since the All-seeing god told him about his mission until this moment...

Invading the planet and seizing its resources is not the same thing as invading the northern region in order to save Richard, the degree of difficulty multiplies dozens of times simply when considering the conquest of the planet as a whole!

Now he is no longer had to think of a military operation to penetrate the lands of the northern region until he reaches the Azil tribe  to bring Richard back, and then quickly returns to the space portal where he can escape, which can be taken down to fighting about 4 northern tribes back and forth, and win.

But if he thinks about the mission in this new view, then it has turned into a comprehensive and total destruction of the planet as a whole!
