Source Power? Sorry Doesn't Work for Me

Rocky, a visitor from another world who "smuggled in", although he traveled through time with his original body, was unable to integrate into the power system of the other world. In this world, the nobles of all races occupy the territory of the branches of the World Tree. Those with blessings can gain the favor of the gods and advance to the extraordinary through the awakening of the source power of the tree species. The bad news is that Rocky cannot awaken the source power of the world and become an energy user with superpowers. The good news is that because of this, while being immune to Source Power damage, it can also repair damaged Source Power creations. Fortunately, the watch that traveled with him also awakened new functions, such as identification and analysis, map navigation, energy contract, and record manual. In this way, Rocky embarked on a journey of collecting and cultivating beautiful girls of energy users from all races, rising from the southern border, and eventually establishing a huge empire.
