"This is an Initiation Ritual Book..."
Han Dong spent a full hour reading through the entire content of the book.
He then understood what the old man, Vogt, meant by his last words before Death, "I have failed."
The Spiralization that occurred to the old man was largely due to his own attempts to learn from the "Initiation Ritual Book," which caused his body to spiralize.
Due to insufficient willpower, he ultimately failed to meet the requirements set forth in the ritual book.
This led to an unstoppable deep Spiralization, until his physical body completely transformed into a Whirlpool, absorbing himself and dispersing among the heavens, never to be reborn.
According to the description in the Initiation Ritual Book, as long as one could meet the ritual's requirements, an individual could begin to master the power of the "Whirlpool" and also become a prospective member of the Whirlpool Cult.
And the last sentence on the final page of the book was heavily marked by Han Dong.
