The moon itself did not glow. It borrowed the power of the sun to glow. The moon that provided the geno art was the same. Its light was used to light up one's spirit, and it worked very well.
But it was hard to find light treasure. For now at least, Han Sen did not know of a location in which he could find something like that.
According to the Moon God geno art, the different light treasures he absorbed would affect the sort of spirit he summoned. It would affect its element and even its shape.
"I wonder if I can find a good treasure here on Planet Eclipse? If I'm unable to, I'll have to head back out there in search of one," Han Sen thought.
But for now, Han Sen was planning on scouring the reaches of Planet Eclipse for one. He had skills, Teeth Rabbit shoes, and Marquise armor to stay alive. He should have no problem doing battle with a Duke, in such a condition.
