Sam holed himself up in the library as he browsed through the information on various trees that produce resins.
The first thing he wanted to do is find a tree that is similar to rubber tree to make some form of material which will not allow the water to go through it.
But he wasn't able to do so, because, there are no records of those type of trees. To put it more bluntly, nobody ever bothered to make a record of these trees which they didn't know how to use.
Then, Sam started thinking in another way. Beast organs. He went through the bestiary again and started recalling all the characteristics of the beasts that were mentioned and after more than ten days inside the library, he found a possibility.
That is to use the stomach sack of a Bladed white shark, this is one of the beasts with strong stomachs that is both physically and against the corrosive and poisonous effects and one more advantage is, there are mutated ones in the indigo patch and he can just buy them off.
