The violent energy within his life seeds made them shine like stars within his body. Not only do they look like stars, but they also behave like stars in that they convert a lot of matter into energy for him to use.
In a way, the 512 life seeds are engines within him just like the engines within cars. So he is a car that possesses 512 engines. If all those engines can work together, one can imagine just how powerful a car he is.
In order to advance to the tenth transformation of the third mortal coil, he has to split those 512 life seeds into two.
To do this, his life seeds must have enough potential to split. If they don't have the potential to split, the process will never start.
As someone who used a top-grade rank 3 armament to build his man-made wonder and establish his foundation, he has to have the potential to advance to the tenth transformation of the third mortal coil.
