"Are these cutting marks strange?" Song Yinuo looked at the ugly piece of iron and said, "why didn''t I find anything special?"


    "That''s because you don''t know the magic of this piece of iron." The staff member smiles and then says, "if I tell you that even with our most advanced technology, we can''t leave any trace on this piece of iron at all, will you still think that the cutting trace is not strange?"


    When he said this, the staff had no choice but to spread out their hands. Even he felt that this piece of iron was incredible.


    "How come Is it possible? "


    The four of them were surprised. It was nothing more than an ordinary piece of iron. With such advanced modern technology, they could not even leave traces?


    If so, the cutting marks on this piece of iron are really strange. Who cut this piece of iron? What''s the way to cut it?


    "We didn''t think it was possible at first." The staff showed a helpless smile and said: "after that, the experts tried various methods, such as high-pressure water jet, laser cutting instrument, etc., and even put this piece of iron under the high temperature of 100000 degrees, but still could not melt it..."


    Can''t melt at 100000 degrees?


    Once again, we were surprised by the introduction of the staff. It seems that none of the metals known by human beings can not melt at the temperature of 100000 degrees?


    When we think of the obvious man-made cutting marks, we can''t help thinking that this piece of iron was left by aliens?


    Once this idea came into being, even they thought it was funny. After so many years of human pursuit of aliens, how could they have made any valuable discoveries?


    "Where was this piece of iron found?" Xu Shaotang stroked his chin and asked with a thoughtful look.


    "Mount Everest!" The staff member said: "it was several mountaineers who first found this piece of iron. One of their companions accidentally fell into an ice cave. When they were rescuing the members trapped in the ice cave, they accidentally found this piece of iron. At that time, they didn''t think much about it. They just thought that since they found it in the ice cave, they just stayed to commemorate their experience of this distress. Later, they found that this piece of iron was extremely hard, so they sent it to the Cultural Relics Bureau. "


    Listening to the staff''s introduction of the origin of this piece of iron, we are even more curious. Many years ago, Mount Everest was regarded as a forbidden area for human beings, and it was only decades ago that people climbed to Mount Everest. Before that, who put this piece of iron there?


    Is it really aliens?


    After thanking the staff, they left the museum with questions.


    "I think that piece of iron is the same as the piece of iron in my hand. It may really be the key to some treasure!" Although Su Ruyun has many doubts in her heart, her eyes are full of stars. In her opinion, the more mysterious this piece of iron is, the more valuable the treasure will be if it is really the key to the treasure.


    Although he doesn''t even have a score yet, Su Ruyun has imagined what he will look like after opening the treasure in his mind.


    At this moment, a picture appeared in her mind. In the picture, in addition to the glittering treasures on the ground, she was the only one. Her hands were full of all kinds of jewelry, and her head was wearing a crown inlaid with a huge night Pearl


    With the deepening of her fantasy, Su Ruyun can''t help being a little crazy. She can even see the saliva left at the corner of her mouth


    He was defeated by Su Yun again.


    Xu Shaotang reaches out his hand, shakes in front of Su Ruyun, who is immersed in fantasy, and appreciates a violent chestnut on her forehead. He says with a smile: "if you continue to fantasize like this, the museum will be submerged by your saliva..."


    "Ah?" Su Ruyun suffered a lot, and then recovered from his fantasy. He wiped the saliva from the corner of his mouth and said to Xu Shaotang discontentedly: "you wake people up when they are going to sleep with a lot of jewelry!"


    Lin Shuying patted his forehead and said with a smile, "Ruyun, you can do this daydream fast enough."


    "It''s not a daydream! I think it''s very possible! " Su Ruyun said stubbornly.


    "In this way, after you go back to Tianhai, see if the piece of iron in your hand is as hard to destroy as this piece of iron." Xu Shaotang stared at the strange piece of iron and said, "if so, this piece of iron and the piece of iron in your hand may really be the key to some treasure..."


    Xu Shaotang didn''t care if this piece of iron was the key to the treasure. He was suddenly interested in this piece of iron because he suddenly had a bold guess in his heart.


    It was because of the lack of key that the ruins, which were found in the depths of Shennong mountain with the alcoholic maniac, were not opened.


    There are also technologies beyond their knowledge. He wondered if these fragments could be the key to the ruins.


    If so, he might be able to solve the mystery of the ruins. Thinking of this, he was vaguely excited, eager to know whether the piece of iron in Su Ruyun''s hand was a key fragment."Well, if I find the treasure, all the treasure will be mine!" Su Ruyun''s eyes are shining, and he looks at Xu Shaotang with pride.


    "Well, it''s all yours. None of us will rob you!" Xu Shaotang jokingly poked Su Ruyun''s head, "you money fan!"


    "I''m a money fan!" Su Ruyun took Xu Shaotang''s arm and hummed Qiong''s nose.


    Looking at Su Ruyun like this, everyone can''t help but smile. This is Su Ruyun, no affectation, no hypocrisy.


    Lin Shuying raised his hand to look at his watch and said, "it''s almost time for dinner. Let''s find a place to eat?"


    In fact, she is not hungry. She just doesn''t want Xu Shaotang to drag her injured body to accompany them. Sometimes, love doesn''t need to be said. It can be reflected incisively and vividly in every word and deed.


    "All right!" Song Yinuo didn''t understand Lin Shuying''s idea, and then said, "I know there''s an old shop in the capital. It''s good to take two elder sisters to taste the delicious food in the capital."


    Su Ruyun nodded and said with a smile, "it''s rare for us to visit the capital. Of course, we have to taste delicious food. Let''s go. I can''t wait!"


    Just as everyone was ready to go to the old store song Yinuo said, Xu Shaotang''s mobile phone rang.


    He picked up the phone, looked at the caller ID suspiciously, and got through.


    When he hung up, he reluctantly looked at the three girls, shook his mobile phone to them, and said with a smile, "we don''t have to go to that old shop. Someone''s treating us to dinner. Do you want to join in?"
