THE EXTREME YIN TREE

"How did you know that there will be  something like this in the Netherworld River?"

"Boy, the treasure you are holding once belonged to the strongest race in the whole universe. Do you think we were called strong for some casual reason? At my peak, I could devour one or two hells easily. But we shouldn't delve into the depths. The main reason for there being a boat in the first place is the corrosive properties of this netherworld river."

"You wouldn't believe it if the boat was constructed of a material that is even precious for me to find out. I could have gone through 4 rounds of transformation if I had just absorbed this boat."

"Why don't we do it then?"

"Because eth Netherwolrd boat is always guarded by a Netherworld captain. A being who has already surpassed the saints level at the very least. Not only will we be captured by it, but you will also die and I will be devoured. You should not have any thoughts about this boat."
