Xu Shaotang looked at her in surprise. Following her eyes, he saw a rusty piece of iron in a humble corner of the museum.

Xu Shaotang shook his hand in front of Su Ruyun and said with a smile, "let's go. What's good for a piece of iron."

Throughout the museum, there are few fragments of this kind of cultural relic. There is nothing special about this piece. I don't know why Su Ruyun has been staring at this piece of iron.

"Shaotang!" Su Ruyun didn't move half a minute at his feet. He just grasped the palm shaking in front of his eyes and looked at Xu Shaotang with a puzzled look. "Do you think this piece of iron looks familiar?"

"Familiar?" Xu Shaotang looks at Su Ruyun suspiciously, then goes over and carefully observes this piece of iron through the transparent glass.

Song Yinuo and Lin Shuying also follow him, looking at this piece of iron carefully, hoping to see what's different about this piece of iron that attracts Su Ruyun's attention.

"It's ordinary." Song Yinuo pointed to the pieces of cultural relics around this piece of iron and said, "there are such pieces everywhere. You may have seen too much and it's normal to look familiar."

Not to mention Su Ruyun, song Yinuo herself has seen it for a long time. Compared with the fragments of cultural relics around her, she thinks this piece of iron is very familiar.

Hearing song Yinuo's words, Su Ruyun didn't speak. He just looked at this piece of iron carefully. He kept thinking about where he had seen this piece of iron.

All of a sudden, she was excited. She finally knew why she felt familiar with this piece of iron.

"I know!" Su Ruyun patted his head and said to Xu Shaotang, "do you remember when we were in the orphanage, uncle Liu once gave me such a piece of iron and said it was the key to the treasure..."

Reminded by Su Ruyun, Xu Shaotang remembers that some lovely crazy old man did give Su Ruyun a piece of iron when they left, but they were fettered by the abduction of orphans at that time, and the piece of iron was too ordinary, so they didn't look at it carefully.

If it wasn't for the piece of iron that uncle Liu gave to Su Ruyun, they might have thrown it away long ago. Who would have had nothing to do with this rusty piece of iron?

After thinking of this, Xu Shaotang carefully observed the iron piece again. Under this observation, he really found a clue.

From the appearance, although this piece of iron has been corroded, there are obvious marks of manual cutting. Unlike other pieces, this piece of iron has a regular shape and should have been artificially cut like this.

"Do you think this piece of iron has something to do with the piece of iron that uncle Liu gave you?" Xu Shaotang points to the iron and asks Su Ruyun jokingly.

Su Ruyun nodded gently, put his head close to Xu Shaotang's side, and said in a low voice: "uncle Liu said that the piece of iron is the key to open the treasure. At first, I thought uncle Liu was talking nonsense. Now seeing this piece of iron, I think it might be true."

When talking, Su Ruyun's eyes are still shining with stars. Xu Shaotang can't help but laugh at the look of the money addict.

The goblin, though worth a lot, is still crazy about money. When the acquisition of Kangle pharmaceutical failed, the goblin was depressed for several days.

Xu Shaotang can also understand that Su Ruyun lived in a different environment from them when she was a child, and she has been supporting the orphanage since she grew up. Money really has a special meaning for her.

"Let's ask the staff about the origin of this piece of iron." Although the probability of knowing that this piece of iron is really a treasure key is very small, Xu Shaotang knows that Su Ruyun will not die if he does not ask about this piece of iron.

Su Ruyun nodded and called the staff of the museum.

"Hello, can you tell me the origin of this piece of iron?" Su Ruyun looked forward to the staff and said, "I'm very interested in this piece of iron. I want to know more about it."

"Is it this piece of iron?" The staff member looked at Su Ruyun with some doubts, pointed to the piece of iron and asked.

"Yes."

"You have a good eye." After confirming that it was the piece of iron she was referring to, the staff member said with a smile.

"What do you say?" Xu Shaotang asked curiously.

Listen to the meaning of the staff, this piece of iron really has a strange origin?

The staff said with a smile, "I've been here for so long. You are the first one to ask me about this piece of iron."

It's not hard to understand. If it's a complete cultural relic, even if its value is not so high, maybe someone who likes it will ask about its origin. But there are too many pieces of cultural relics here. Who would have noticed such a small piece of iron?

Even if we have noticed it, I am afraid we will only regard it as an ordinary piece of cultural relics, which can not arouse people's interest.

"Please tell us the origin of this piece of iron in detail." Lin Shuying is also interested in what they say, and wants to know what's different about this piece of iron.The staff member nodded with a smile, looked at the piece of iron lying there quietly through the transparent glass, and said: "in fact, we know nothing about the origin of this piece of iron. Many archaeologists have studied this piece of iron before, but they can't tell its origin, and even can't figure out its age. Later, everyone lost interest in this piece of iron. "

Listening to the staff's introduction, Xu Shaotang found the problem and asked, "this kind of iron sheet without research value should not be put here, right?"

If any piece of scrap metal could be put into the museum, the largest museum in China would have been covered by scrap metal.

In that case, it will not be called a museum, but a place to collect waste products.

The staff nodded and explained with a smile: "originally this kind of iron sheet with unknown origin can't enter our museum, just because this iron sheet is too strange..."

"What's so strange about it?" Xu Shaotang looked more puzzled at the staff, "isn't there a man-made cutting mark?"

If it wasn't for the man-made cutting marks, it's estimated that this piece of iron would be recycled as waste. How could it lie quietly in the museum.

"Yes, it's because of these obvious man-made cutting marks!" The staff looked at Xu Shaotang with admiration. In his opinion, it is very rare to pay attention to this piece of iron, and to find the obvious man-made cutting marks on the iron, which really needs careful observation.
