Jing Xiaolei passed the name over her head, turned her head to Cao Xueyang and asked: "I don't know too much about the history of Japan, so I call her ....... What century was the Yayoi period in Japan? ”

Cao Xueyang thought for a moment and replied, "The Yayoi period was about 300 BC, after the Jomon period, before the Kofun period, around the 3rd century BC. ”

Jing Xiaolei said: "Then this skull, the key to the problem of death, is here." ”

Cao Xueyang was curious: "What's the problem?" ”

Although Jin Erniang didn't say anything, she also put down the water glass and listened carefully.

Jing Xiaolei said, while magnifying the photo several times with her slender fingers, pointing to the scar in the picture and continuing: "At that time, iron swords were already popular. However, it was impossible to produce a knife with this process with the iron smelting technology of Japan at that time. ”

As soon as the words fell, Jin Erniang was stunned, obviously, she had never thought about this problem before.

After a pause, Jing Xiaolei said again: "You see, this wound is narrow in front and wide in the back, with a slight arc, and it is a double-edged rather than a single-edged. ”

Jin Erniang was puzzled, obviously she didn't understand, she looked at Jing Xiaolei with an extremely puzzled look: "What's the difference?" ”

Jing Xiaolei looked at the pitch-black knife in the picture, with a serious expression, and said: "Although I am not good at humanities and history, but I have some research on cold weapons, as far as I know, the earliest existing iron sword in Japan is in the middle of the Kofun period in Japan, the "Golden Wrong Ming Iron Sword" unearthed from the ancient tomb of Inari Mountain, the shape of the knife is different from the common Japanese sword now, its appearance is not like a sword, more like a gold broken iron rod. Swords before the Heian period are all classified as the system of the ancient straight-edged sword. ”

Cao Xueyang was in a trance, and suddenly said: "That's right, the shape of the Japanese knife we see now is originally derived from China's ring head knife technology, from the fifth century AD, that is, the late Heian period to the Kamakura period, after the introduction of horizontal knife forging technology, there is now a two-edged structure, and with an obvious curved knife reverse 'hair-drawn' type Japanese sword." ”

At this time, Jin Erniang obviously understood what Jing Xiaolei meant.

She blinked, lit another cigarette, took a puff, put it down, and lit another.

Jing Xiaolei was categorical and said: "The evidence is obvious, in the Yayoi period of Queen Yamadai, there was a katana that would not appear in the Kamakura period or even later, and according to my speculation, the real cause of death of this Himiko was not the piercing knife wound on the cheekbone in the picture, but the part that was not photographed in the photo - it was caused by someone who had his head cut off."

When Jin Erniang heard this, she nodded and agreed.

Cao Xueyang smiled at Jing Xiaolei and praised: "It's so amazing, I feel that it's like solving a higher equation, you have to assume an unknown first, and then solve it step by step." ”

Jing Xiaolei shook her head and said: "This is just my personal argument, there has been no on-site investigation, everything is just speculation." When she said this, she suddenly paused, squinted at Jin Erniang, and said mysteriously: "I have also heard a little about the various rumors about the Queen of Yamatai, and I heard that Himiko used the 'ghost and god way' to quell the civil strife and ascend to the throne at the age of 17. She lived in seclusion, did not ask about the world, and used mysterious power to deter the people, thus ending the situation of the three-way melee between Yamatai and Yamatai. However, these are only the queens recorded in the history books. According to various wild historical records, Himiko is a supernatural person who can spread death and calamity at the touch of his fingertips. Another example is that the queen is an 'immortal ......'"

When Jing Xiaolei talked about "the immortal", her voice deliberately accentuated her tone, and even, intentionally or unintentionally, she looked at Jin Erniang's face - trying to capture any useful information from the other party's expression and eyebrows.

Then, she was disappointed.

Because, Jin Erniang's face did not appear unnatural, and even pretended to be thoughtful.

It's really worth living for thousands of years....... Inhuman?

After being silent for a while, Jin Erniang just took a deep puff of cigarette, suddenly clapped her hands and applauded, "You really deserve to be an expert, little sister." It's just—"

"Just what?" Jing Xiaolei asked.

Jin Erniang smiled meaningfully: "Why do I always feel that you, sister, don't look like an archaeologist, but more like a policeman?" Is it my delusion? Hey, hey—"

As soon as the words fell, the joints between Jing Xiaolei's fingers seemed to vibrate unnaturally, although they disappeared in a flash, they did not escape Jin Erniang's eyes, the latter snorted, and Jing Xiaolei was just stunned for a moment, and suddenly giggled, and then, Jin Erniang also smiled.

At that moment, the secrets of the two were discovered by each other, and they tacitly knew each other.

This operation made Cao Xueyang next to him confused, and he couldn't help but secretly pay these two people, do they know each other, or don't they know?

Jing Xiaolei was also generous, standing up with "Teng", and stretched out her hand while saying, "Hehe, the proprietress has a very accurate intuition; As for me, it's not Li Yushan, my name is Jing Xiaolei. Of course, Li Yushan is also a colleague; And she is indeed an excellent forensic worker. As for my profession, it is indeed a police officer, but it is not the traditional one. ”

Jin Erniang said "ah", and immediately stretched out her hand to shake her, while shaking her hand, she smiled and said: "I just now, I forgot to introduce myself, I used to use my name, and my name is indeed Jin Erniang." Later, I changed my name and now I am called Jin Yier. Before opening this café, I opened an inn in Zisai, hehe, it's the kind of inn you have in mind, not the big hotel now......."

When Jing Xiaolei heard this, she grinned, and it can be said that she was right, the person in front of her was indeed Jin Erniang herself.

You don't lie to me, I don't hide it from you, what if you live for a thousand years? Generously admit that it is!

Jing Xiaolei was very happy, Jin Erniang's honesty was based on her making a decision right away.

That is, to keep the secret of Jin Erniang's 'immortal'.

After all, if Cao Xueyang knew that the café proprietress in front of him was a "living fossil" who had lived from the Northern Zhou Dynasty to modern times, wouldn't he be crazy?

It's just that if this secret is spread to the society, with the current traffic capacity of the self-media, within an hour, the whole world will know about the existence of immortal people.

At that time, I am afraid that it will cause an uproar and lead to a lot of unnecessary trouble.

After all, Jin Erniang's body, I don't know how many stories have been submerged by time?

Even, she casually said some things from the past, which is enough to subvert the entire archaeological community today.

Thinking of this, Jing Xiaolei seemed to suddenly remember something, covered her stomach, and said with a smile: "Alas, why am I patronizing and talking?" Boss, what about the meal I ordered, why hasn't it been served yet? Starve to death ......."

Jin Erniang understood, hurriedly got up, and said with a smile: "Don't worry, I'll go to the kitchen to have a look, you can sit down for a while." ”
