i think jin loong sends all the ten deity on earth to be safe from the approaching revenge of *i-forgot-the-name*
he knows he's getting weaker as years goes-by and his ability to hold back the enemy gets weaker too, hence he decide to make a sacrifice. sending the other deity to have baby is like making a stronger bond between every deity. the stronger the bond they make, the stronger power they contain. jin loong gets weaker because he lose someone *that-one-might-be-someone-special-to-him* i think my explanation is crap, sorry
