In Pokémon, I Am Weak, Tench, and I Rely on Thousands of Descendants to Become Strong.

Long Ze accidentally traveled through time with his Grand Luck and became an ordinary weak tench. The elves who originally seemed cute also had a competition between life and death. In the dangerous ocean environment, Long Ze obtained the descendants system. As long as the descendants pass on for more generations, they can get system bonuses. Friendly reminder, elves are all anthropomorphic. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
