When the old man heard the term 'Formless Body' from Adrian's mouth, he became speechless as that term is not to be taken lightly. Even Jihan is shocked upon learning that as that is the perfect body for martial arts.
For martial artists, having a formless body means that one can learn any type of martial arts. Even martial arts have body requirements which is why not just anyone can become a member of a sect. With the formless body, the person is guaranteed to learn the martial arts perfectly without obstruction and can even use other martial arts in the process even if it is opposing the teachings of his foundations.
"Jihan! Now that grandfather has ended his seclusion, do you want to return here permanently to learn from me?" The old man stated as having a Formless Body change everything. He wanted to personally train Jihan so that his talent could exponentially increase.
