Yan Aohan smiled faintly and extended his hand. A similar book appeared in his palm, but this one was black, bearing the four large characters Book of Heaven, Earth, and Man.
"The Book of Heaven, Earth, and Man appeared after Heaven, Earth, and Man came into existence. The Heaven Book is the oldest and is now held by the Supreme Immortal Emperor Ouyang Mingyue, used to stabilize the heavens.
However, where there is Heaven, there is Earth. When Heaven moves, Earth naturally changes. Thus, the Earth Book was born with Earth. Its purpose is to record the rise and fall of all life in the world. Just as Heaven has destiny, Earth has fortune. So the Earth Book stabilizes the Earth. This one in my hand is the Earth Book, and it was also the birthday gift you gave me, Ani." Yan Aohan spoke with a smile.
"Actually, I have been searching for the Earth Book. Its disappearance was not good for all things in the world. Without predicting their life fluctuations, strange occurrences would arise. Fortunately, the Earth Book has reappeared, so there is no need to worry about other matters." With the Earth Book, Yan Aohan felt like a tiger with added wings. Of course, the Earth Book had returned to its rightful owner. If it were anyone else, even if they obtained the Earth Book, it would be useless. Yan Aohan did not mention this.
"Ani, the book now in your hands is the Man Book. The Man Book is for guiding people. This means that with the Man Book, one can judge the good and evil of people. Its function is similar to the Immoveable Wisdom King in the Buddhist realm: suppressing evil, promoting good, using evil to counter evil, or guiding people through goodness. These will be your mission.
You were originally a doctor and also the Medical Buddha Maiden. So, the Man Book in your hands will naturally exert its greatest effect." Yan Aohan explained to Zhu Yanyi with a smile.
"How do I put it away?" Zhu Yanyi looked at the book in her hands. Her own existence was already mystical, so the appearance of the Man Book, while still feeling fantastical, was not unacceptable.
"Just think about storing it, and it will naturally hide inside your body. When you want it out, just think about taking it out, and it will appear." Yan Aohan guided Zhu Yanyi in controlling the Man Book.
Zhu Yanyi followed Yan Aohan’s instructions, practicing storing and retrieving it a few times. After storing the book in her body again, she tilted her head and looked at Yan Aohan: "How do you know so clearly?"
Yan Aohan also put away his Earth Book and led Zhu Yanyi to the window. "The Yan family has existed since the first civilization. We have seen too much, which often leads to treating things with indifference. The Earth Book is under my control for this reason, because I am impartial.
The three realms of Heaven, Earth, and Man each have their rulers, but all life needs someone to preside over it. I am the chosen one, so I naturally know these things."
Yan Aohan looked at Zhu Yanyi and said, "Ani, I should not tell you too much about the function of the Earth Book. But you must know one thing about the Man Book: it is relative. Because among all living beings, humans are the most intelligent and the most perfectly evolved creatures."
Yan Aohan’s expression was serious. Seeing him so serious, Zhu Yanyi unconsciously listened attentively.
"Because humans are perfect creatures, many spirits transform into humans. This is why there are various humanoid monsters in early legends. But monsters are still monsters, not humans. They lack human aura. They become human to experience human tribulations and thus improve their cultivation.
On this point, the Man Book records very clearly. There is still a difference between humans transformed by monsters and real humans."
