"Sure! The fundamental is to absorb Celestial Energy. Upon doing so, there are only two paths to go. You either reach to become a black hole or a constellation. The former route focuses on sheer absorption of power. Just absorb as much energy as you can, condense it as much as you can, be powerful as much as you can. Very straightforward. The latter moves in steps. Continuously seeking to create stars in their body and form a constellation. The latter is also the textbook way to do it as it is the will of the tower. In terms of power, the two are just equal. There is no domination between the two paths at all. May I know what path you will take?"
"I will take the path of constellation." Z immediately answered. He finds the concept of black hole boring. Knowing that there is a definite balance between the two types of power, he chose the one he will enjoy.
