In order to transcend the third mortal coil, he must first fill up all of his life seed with energy. The next thing he has to do is make sure that he has mastered the host technique to 100%.
The host technique is not only useful for transforming potential into power, but it is also important for determining the chances of success because mastery of the host techniques influenced just how well the numerous life seeds within him work together.
The process of advancing to the fourth mortal coil is very easy. One just needs to fuse their life seeds into one large organ called the golden core.
The minimum amount of life seeds needed for the golden core to form is 100 life seeds. But one can form a higher-quality golden core by creating it with more life seeds.
The most important factor that determines the number of life seeds that can be fused is the mastery of the host technique, not the level of transformation of the host technique.
