Energy Convertion
"If only there were Qi in this world, or at least mana that could be used... eh? wait a minute," Del's eyes widened, realizing something.
Why does he think he can't use mana?
It's because every time Del tries to cultivate with mana, his body absorbs it and turns it into K nutrition. K nutrition is a very important energy that is capable of making Kylia's Sacred Seed sprout in just a few years.
If the Sacred Kamboja Tree is equivalent to Ayam Cemani, then the Sacred Seed is sure to be equivalent to the Point Star. Thus, for the Sacred Seed to sprout, it requires the same amount of energy as the Point Star exploding and becoming a Nebula Supernova. Therefore, K nutrition (mana that Del absorbs) has enough energy to form a new Point Star.
Therefore, it can be concluded that Del is not unable to use mana, but he is only unable to use K nutrition to cultivate. Then the question is why does mana turn into K nutrition when absorbed into Del's body?
