My Mythical Beast Doesn't Have a Fuel-Efficient Lamp

Instruct gods, demons and beasts to revive, gain a share of supernatural powers, and embark on the road to becoming the most powerful. There is a contract system between gods and demons in Li Jun's head. As long as he helps the gods and demons after the contract revive their magical powers or the strongest ancestral blood, he can get half of the other party's magical powers. But he found that these descendants of gods and demons seemed to have some problems with their heads. Some of them love to listen to inspirational stories, some just want to find a wife and live a good life, and one has been studying whether mythical beasts should be eaten raw or roasted... Some are so lazy that they die... Hey! Damn it, every one of them doesn't have a fuel-efficient lamp! ! !
