Gray impermanence does not understand the eating habits of white very well. But even though there were only two and a half days left, he had already asked the obvious time-wasting question of why Onita ate corpse meat.

"It's like beasts eating people." Bai chewed and said: "After becoming a ghost, you are not a human being, so human beings are no different from other creatures for us, and human flesh is a gathering of yin qi, which is quite complementary to ghosts and demons." ”

“…… Yin energy gathering? Gray Impermanence said, "What do you mean?" ”

"Have you ever heard of Nuwa making people?"

"Of course."

"Have you ever heard of the groundbreaking?"

"Is there anything to do with the two?"

"Pangu opened the heavens and the earth, the clear ones rose to the sky, and the turbid ones sank to the earth; Nuwa kneaded the soil to create people, the hand pinching was for the nobles, and the rope throwing was for the cold soldiers. ”

Gray Impermanence reacted for a moment, suddenly understood, and said, "So the human body is formed by the condensation of turbidity?!" ”

After Bai finished eating the corpse meat, he clapped his hands and said: "Turbidity is yin qi, these are very complicated, and I can't explain it clearly for a while." If you just want to learn these nonsense theories, then I can give you two days of lectures for you to use as a writer in the future. ”

Gray Impermanence hesitated in embarrassment, lowered his head and said, "I'd better obey the arrangement." ”

Shiro nodded, reaching out and pulling out a green waist tag from his arms. He put the waist card on the table, stood against the corner of the wall, shook his sleeves, and threw out three incense sticks, which were lit in a bowl full of rice. After fiddling, she crossed her arms and said:

"Get on your knees."

Gray Impermanence knelt down.

"I'll say a few words, and you will say a few words." Said in vain.

Gray Impermanence looked up suspiciously, he didn't understand, it sounded like his apprenticeship ceremony would be very hasty.

Shiro knelt on one knee in front of the token, but his face was nonchalant.

"Leader, I'm going to pass it on to this little cub twice. I also learned this trick from you, and now I want to teach others, so I can't help but inform you, if your old man has an opinion, it is estimated that it is enough to put it forward, and I will acquiesce to you. ”

After Bai finished speaking, he nodded at the token, which looked like a minimalist version of a bow.

Gray Impermanence looked at Bai and felt speechless.

"You...... Who are you talking to? ”

"I lead." After Bai finished speaking, he thought for a while, and then said, "Of course, it's also my master." ”

“…… What exactly is this relationship? ”

"Don't talk nonsense." Bai slapped him on the back of the head and said, "It's your turn." ”

"I said that too?" Gray impermanence said.

"Of course not." Bai Dao: "You swear two oaths to me." ”

"What oath?"

"First, never use the techniques I taught you to do evil, and cause chaos."

Gray impermanence nodded and said, "This is nature, and it must be unrighteous." And second? ”

"Second, we are not allowed to recognize our master-apprentice relationship with anyone."

Gray Impermanence was stunned for a moment, and then he was silent for a long time before he said slowly: "Does it have to be like this?" ”

"Yes." Bai said lightly: "I am a ghost and you are a human, and our magic cannot be passed on to the living, so the benefits and disadvantages of it, with your intelligence, you will definitely be able to figure it out." ”

Gray Impermanence closed his eyes, and only after a moment did he say in a deep voice:

"Understood."

"What if someone asks about you?"

"I learned it from someone unknown, and that's what I've always done anyway."

Bai nodded and said, "Swear." ”

The gray nose was a little sore, and a few tears swirled in his eyes. He took two breaks from his oath, only to be relieved by taking a deep breath.

Bai looked at him, a trace of compassion flashed in his eyes, but it was also fleeting.
