Samanuel's proposal sounded like a blank check, but Andrew was smart enough to know that there was nothing as good as a blank check in any world.
It's not really a problem for Andrew to give him the formula for the fertility matrix he possesses, since other than serving to have children with his wives, which they don't plan to do at the moment, there was no other use for it.
Samanuel wasn't asking him for the materials or to build the matrix, or anything like that, so it really was a simple deal. In another scenario, there would be nothing to think about, just ask for something you need and accept.
Unfortunately, Crhono had already told him about the angels' situation and his concerns. According to Crhono, it was unlikely that that was what the angels wanted. It might be true that they need to increase the birth rate of their race, but Crhono had a feeling that there was something else that Samanuel wasn't saying.
