"Yu Ge, we can put aside the matter of where this sachet came from for a while." I interrupted her. "We should think about what this sachet has to do with the spell we're about to crack."

She just smiled weakly. "Who said there must be a connection between the two. These are two different things. But now one thing is certain, the Taoist priest you are talking about is really capable of predicting your journey. ”

"yes, that's weird." I didn't expect it to be said by Daoist Zuo. "But I still think that since he could have foreseen that I would meet you, he could have also expected us to be racking our brains to crack this spell, and maybe this sachet was really a hint."

Yu Ge shook his head helplessly, and carefully stored the feather and a pile of sawdust into the sachet. "I hope so."

"Let's start with your ancestor Bi Fang first." For some reason, the name Bi Fang always sounded familiar. "I always feel that there is a legend of her in the human world."

"Impossible!" Yu Ge interrupted me. "Our ancestors have always lived on Bird Island, how can it be recorded in your culture?"

"I'll show you!" I inadvertently had a disagreement with Yuge, but I could feel that this disagreement was the key to solving the puzzle, because Bi Fang represented the history of their clan, and figuring out Bi Fang's background was tantamount to figuring out their history.

I opened the ancient book "Classic of Mountains and Seas" that I borrowed earlier, and the reason why I chose the ancient book is because many adaptations have been made to this book in later generations, and only the illustrations in the ancient books can maintain the original flavor. "Look at that." I showed him a fragment from the "Western Mountain Sutra".

"There is a bird, its shape is like a crane, one foot, red and green and white beak, the name is Bi Fang, its song is also screaming, and there is a fire in its city when you see it."

Yu Ge still kept shaking his head. "This may just be a coincidence, and this is just saying that Bi Fang is a bird, and my ancestor Bi Fang is obviously a god with high mana."

"Then look here." I turned to the next page, which is the description in the Overseas Southern Classic. "Bifang bird is in the east, green water in the west, it is a foot in the face of the bird. One is said to be in the east of the two eight gods. ”

"It's a kick in the face of a bird!" Yu Ge recited repeatedly. "This ......"

This has really answered this question, their ancestor Bi Fang did live in the Central Plains.

"Yuge, I have long felt that there is something strange in this, you said earlier that your people have lived on Bird Island for generations and do not communicate with the outside world, but that day I saw the architecture and planning of your people, and it was obviously the same as the human world."

I output Bi Fang's name in the library retrieval system, and the system recommended several other ancient books to me one after another, namely: "Divine Strange Sutra", "Han Feizi", and Zhang Heng's "Tokyo Fu".

"Divine Sutra": Bi Fang, wood spirit, like a bird, cyan, barefoot, two wings and one foot, do not eat grains. Seeing it, there is a fire in the city. It is the god bird of the Yellow Emperor's car.

"Han Feizi": The former Yellow Emperor joined the ghosts and gods on the West Qin Mountain, drove an elephant car and the world was harmed.

"Tokyo Fu": "Bi Fang...... The old father God, like a bird, with two feet and one wing, often causes strange disasters in others.

These three books, together with the "Classic of Mountains and Seas" just now, can be said to have vividly depicted Bi Fang's life experience.

"Izumi, I now believe that my ancestors inhabited your world, but what do these historical sources say?" Yu Ge looked at a few paragraphs of text repeatedly, but he still couldn't understand it.

"This explains why your people have been hostile to humans for generations." Oh my God, please shine. "First of all, your ancestors were born and died with the Yellow Emperor, made great achievements, and were the founders of the human world, but later there may have been some misunderstanding, and she began to take revenge on human beings, causing disasters, and changed from a divine bird in everyone's mind to a fierce bird. Moreover, I can also infer from the "Classic of Mountains and Seas" that Bi Fang's range of activities is gradually migrating from west to east. Because she first appeared in the "Xishan Jing", and later was included in the "Overseas Southern Classic". ”

Yu Ge was a little dumbfounded. "Izumi...... I didn't expect your analytical skills to be so ......"

"And I have a bolder conjecture, not only your ancestors have existed in the Central Plains, but even your normal clansmen have lived in the Central Plains for a long time." The reason why I dare to say this is because I have read the "Classic of Mountains and Seas" many times before, and when I saw those bird-headed men on Bird Island that day, I felt that they were very similar to several ethnic groups in the "Classic of Mountains and Seas".

They are the Yu Republic and the Tou Kingdom. The similarity between these two ancient groups and the bird-people on Bird Island seems to me to be as high as ninety percent.

I skillfully flipped the pages to Yu Ge to read.

"The Classic of Mountains and Seas: The Great Wilderness South Classic": A country with feathered people, its people are all hairy.

"The Classic of Mountains and Seas, Overseas Southern Longitude": In the Republic of China, the people have wings, they can't fly far, there are many birds, and the people eat their eggs. Go to the Nine Doubts 43,000 miles

"The Classic of Mountains and Seas, Overseas Southern Classics" is in the south of the country, which is everyone with wings, a beak and a fishing. One is in Bifangdong. Or Zhu Guo.

The illustration on it made Yu Ge very stunned, and the seemingly simple charcoal drawing has vividly expressed all the characteristics of the birdman. "Too ...... It's so similar! ”

"You see, first of all, we can confirm that this Republic of China and the Toutou Kingdom are actually exactly the same, their images are completely identical, and what they present is almost exactly the same migration route as Bi Fang." I went on to reason.

"Yes, and it has been clearly written here that the country of Toutou is to the east of Bifang, and the two are adjacent." Yu Ge echoed, and his excitement overflowed. "This should be our people!"

At this moment, I felt that our decipherment work had finally begun, and suddenly there was a light in the darkness, and once there was a glimmer of fire, the whole light was not far away.

"Also, you see that there is such a sentence in the explanation of the Republic of Yu, the people eat their eggs. What kind of eggs are you eating? "I feel like my whole mind is cleared up at the moment." I guess it's Bi Fang's bird eggs that I eat. ”

"Huh? This ......" Yu Ge was frightened.

"Yu Minguo should have been a human like me, but because of eating Bi Fang's bird eggs, they were deformed, and they became what they were recorded in the book." Although it is easy to say, it is really scary to think about it. "Considering that Bi Fang has been taking revenge on humans in the later period, I boldly speculate that these bird eggs are also the product of Bi Fang's revenge on humans, and the ones she retaliated against should be men."

These words may have been a little too subversive, and Yu Ge looked at me stupidly, unable to say anything with his mouth wide open.

"That'...... Then we ......" Yu Ge didn't dare to say any more.

"Your race is the creation of her revenge, and her original intention may have been revenge, but she accidentally cultivated a new race." I said calmly. "Later, the intermarriage between your races continued to multiply the bloodline of the bird-man race, and as a result, the male lineage of the human body and the female lineage of the human-faced human body were formed."

I pulled the fifth volume of Torishima out of a pile of books, and our desks were in shambles.

"That would explain the first line of the poem." I said slowly. "Half white pigment and half yellow, not what plant fruit we are talking about, but what we are talking about is bloodline."
