"Mother-in-law, you're here too." The boy saw the old woman standing at the bar.

After speaking, he glanced at the cigarette she was holding in her hand, and said with a smile: "You better smoke less." ”

"Hairy boy." The old woman's eyebrows raised, and she took another puff of her cigarette: "Don't talk nonsense until you understand the burden on the old man." ”

"Huh." The boy sneered, and the old woman of the tavern was still saying things that people couldn't understand, as before.

The boys and girls sat down at the bar.

"What do you need?" A faint voice asked from the side.

The boy turned his head and saw the waiter walking over, and smiled slightly: "Sister Nan." ”

Then he pointed to the girl next to him and said, "This is my classmate." ”

The girl sitting next to him abruptly looked away from the somewhat scary old woman.

It also fell on the waiter's body, and there was a bit of amazement in his eyes.

"Hmm." The waiter answered and said hello, and continued to ask, "What do you need?" ”

The boy held out a finger and said, "A fried rice." ”

The girl looked at the waiter, unconsciously a little nervous, and said, "I want a fried rice too." ”

"Hmm." The waiter nodded, rolled up his sleeves, and walked towards the back kitchen.

The girl cautiously leaned over to the boy next to her and said, "The waiter just now was so handsome." ”

"Hmm." The boy also nodded in affirmation: "She is indeed a very handsome girl." ”

But he quickly remembered what he was going to do today, and reminded, "Let's take a look at the topics left by the professor." ”

"Yes, yes, yes." The girl also reacted, nodded again and again, put down her backpack from herself, and took out a few photos from her bag.

"No, this is the subject that the professor left behind." The girl said and handed the photo to the boy.

The boy took the photo, lifted his glasses, and looked at the things in the photo.

They are archaeology students at a nearby university, and their professors recently participated in the excavation of an ancient site on the edge of the Wei River, which has not yet been made public.

It is not clear what kind of ancient ruins it is, but during the excavation, the professor took a few photographs of one of the well-preserved and very representative objects for them to use as a subject.

They need to use these photos to determine the age of the item, its affiliation, its origin, and so on, as detailed as possible.

In pairs, the two of them were divided into groups.

For the best group of the project, the professor will take them to participate in the excavation of the site.

It can be said that this is a very rare opportunity, and if you seize it, it will be extremely helpful for your studies and future.

The boy looked at the photo in his hand and frowned.

The photograph shows a broken spear, which is supposed to be made of iron, judging by the rust on the spear. The total length should be about two meters, and what is even more surprising is that the entire spear seems to be made entirely of iron.

The lines on it are not very clear because of the rust, and it is difficult to distinguish from the outline that it is the pattern of that dynasty.

"A two-meter-long one-piece iron tool, if it can have such a forging process, it should be able to exclude the dynasties before the Tang Dynasty."

"yes, that's what I thought of too." The girl said and pointed to the spear in the photo: "If it is made entirely of iron, such a spear cannot be a standard equipment, it should be used by generals." ”

"I have checked that there are many people in history who are good at using iron guns and spears, and there is a record among them: Kuijie Shen Yong, Duoli is good at fighting, the spears used are all forged with pure iron, and the guns weigh more than 30 catties.

After speaking, the girl made a wise appearance and continued.

"According to my inference, since the professor asked us to make a certain judgment based on these few photographs, it is likely that this spear is recorded in history, or there are traces to follow. Otherwise, he wouldn't have asked for a statement of belonging. You're right? ”

Is this based on the photos?

The boy wiped the sweat from his forehead, but it didn't seem impossible when he thought about it: "Maybe······"

"Fried rice for two." With a voice, the two turned their heads.

I saw that the waiter had already walked out of the back room with two plates.

The plate is topped with two servings of golden fried rice, which is simple but smells very tempting.

"Goo." The girl swallowed.

The boy smiled and said, "Thank you, Sister Nan." ”

"Hmm." The waiter shoved two portions of fried noodles in front of the two of them.

The girl noticed the waiter's right hand, which had a scar that ran through the palm of the hand, which looked a little hideous.

There was a bit of pity in his eyes.

The boy took the plate, picked up the spoon on it and took a bite, with a look of enjoyment on his face.

waited until he swallowed it, and then said to Gu Nan: "Sister Nan's craftsmanship is getting better and better. ”

"Well, thank you." The waiter picked up two cups and walked over to the bar to pour water.

"Hmph, she'll only be able to fry rice." The old woman at the bar said lightly.

The girl looked at the fried rice in front of her, she didn't notice it just now, but now she remembered that there was still such a thing as fried rice in the tavern?

I thought about it, but I picked up the spoon on the plate and tasted it.

His eyes were stunned: "Hmm, it's delicious." ”

As he said vaguely, he added the grains of rice that fell out of his mouth back to his mouth and chewed it.

"Water for two." The waiter poured the water and placed the glass beside the two of them.

Eyes fell on the photo placed between the two.

Seeing the broken spear in the photo, her eyes were stunned, and she looked at it with some distraction.

The boy seemed to notice the waiter's gaze, took a sip of water and said with a smile: "This is our subject, to analyze this spear, if it is done well, we can go to the site to study." ”

"What age does Sister Nan think this spear should be?"

It was just a boy who asked casually, but the waiter paused, but said: "From the end of the Warring States period to the end of the Qin Dynasty." ”

The boy and the girl were stunned, then looked at each other and smiled, there was a rare opportunity to show their professionalism, the boy coughed and explained seriously to Gu Nan: "Sister Nan was in the late Warring States period and Qin, although some areas already had the ability to forge iron tools, but most of the iron tools were still used for the production of farm tools. It was not until the Han Dynasty that iron weapons began to replace bronze weapons in an all-round way. And with the production ability of that era, it was impossible to build a two-meter-long pure iron spear. ”

After saying that, I was expecting to see some surprise and admiration on the waiter's calm face.

As a result, the waiter just nodded lightly: "I know, but this spear is not integrated, but spliced." ”
