"Kneel and beg you to rent a car, why do you want to ride a bicycle, I have money!" the fat man complained, and finally put his cycling clothes in, but the seat cushion didn't seem to be able to meet the area of his buttocks, and the fat hung down under the seat cushion.

Fang Jingxuan looked at his embarrassed appearance, couldn't help but want to laugh, turned his head to look at Haichuan, and always felt that this teacher was doing something unreasonable, which made people feel unreliable, but judging from everything that happened, it made people feel mysterious.

"Teacher, tell me what you think. ”

"Thoughts?" Haichuan looked at her and smiled slowly, "I have a lifelong wish, I don't know if he is unattainable!"

Looking at his suddenly gloomy face, the desperate expression that seemed to see the vastness of the universe and lamented his own insignificance, like the helplessness when he discovered the truth of something, she actually felt a little distressed, and she was close to him.

"Did you find something you couldn't understand?"

"Hmm!" Haichuan nodded, shoulder to shoulder, looking weak and pitiful and helpless, and the fat man in the back looked at this old-fashioned trick and kicked his ass with his foot.

"What's wrong with you?"

"Nothing, quietly...... If I uncover the truth, it will bring doom to all mankind," Haichuan said, grabbing Fang Jingxuan's shoulders and slowly approaching her (this little girl is really fragrant), looking at her suspiciously, "Will you stand on my side?"

"Quietly?" she was stunned for a moment, feeling a little uncomfortable, but realizing the seriousness of the problem, she thought about it seriously.

"Beast ......," the fat man muttered quietly, and then sang loudly, "Big brother flows eastward, and the stars in the sky ......"

"Sister Xing, are you so loud that you call your soul?"

"Ahem, we've been standing in the Xining Cultural Relics Restoration Bureau for a long time, do you think we should go in or not......? "The last two words of the fat man were squeezed out between his teeth.

"Then let's go in, by the way, fatty, quietly she's thirsty, you go buy her a bottle of water." ”

"I'm fine, sorry to bother. Fang Jingxuan hurriedly said politely.

"Did you hear that, the beauty is so tactful and polite, don't you understand? I also want a bottle, three yuan of iced tea, less sugar and seventy percent ice. After speaking, she walked towards Fang Jingxuan, "Then let's go." ”

Fat man: "Less sugar and seventy percent ice, you should eat steak, my Nima ......"

"Is Professor Qiu here?" Haichuan politely asked the security guard. The security guard looked at them and saw that Haichuan and the three young people knew Professor Qiu's name.

"That's right, we were introduced by someone from the Xining Museum, and we would like to visit Professor Qiu. The fat man handed the business card of the eldest sister in the museum, and the security guard looked at the business card suspiciously, with an obviously unhappy expression on his face, but he still showed them the way.

When I came to a room with a glass door, I could vaguely see a figure.

"Anyway, don't talk to me about going on a field trip. Haichuan and the others had just knocked on the door, and they heard the professor impatiently reprimand, driving away a few business people in suits.

"Hello, Professor Qiu. ”

"Where are you profiteers, trying to coerce and lure?" Professor Qiu said in a low voice, harshly, although he looked gray, but in fact he was about fifty years old, wearing gold-rimmed glasses, looking full of scholarly atmosphere, obviously a Sven person, deliberately difficult to appear unnatural.

"Professor Qiu, you misunderstood, we were introduced by the museum, I was admitted to the hospital because of this sword, and I almost went to the police station, so I want to take a look. Haichuan took a step forward, a polite smile on his lips.

Professor Qiu was stunned for a moment, and his eyes looked up and down, left and right on Haichuan's body with curiosity.

"Is it that the big professor has been in office for a long time, and there is a bit of a problem with that?" the fat man pointed his finger at his temples and drew circles, and asked Fang Jingxuan in a low voice.

"Little fat man over there, don't think I'm old and have bad ears. ”

"Thank you, Professor Qiu, for the compliment, hehe, I have been laughed at the big fat man, and I am really happy to be praised for the first time. The fat man came to him with a grin.

Haichuan and Fang Jingxuan looked shocked, they had never seen such a brazen person.

Professor Qiu didn't seem to be able to stand it either, and didn't want to deal with him, so he retracted his gaze and fell on Haichuan. He was obviously thinking, and at the same time touched Haichuan with his hand, frowned, and even pinched it directly, like Haichuan is a rare strange thing.

"I heard that you were the last person to come into contact with this bronze sword?" Professor Qiu said, looking at Haichuan.

Haichuan didn't quite understand the meaning of his question, because in the museum, he hadn't paid attention to the bronze sword next to the fossil at all, and he didn't know if he had touched the bronze sword when he fainted later, but when he saw the sword in front of him, his eyes slowly changed.

"What's wrong?" Fang Jingxuan asked in a whisper as he approached him.

"Don't you think it's strange how this sword became rusty?" Professor Qiu stroked the rusty sword with gloves, "It stands to reason that the oxidation rate of bronze occurs relatively slowly under normal circumstances, but since that accident, it has suddenly rusted like this, and the museum personnel don't know the reason." ”

At the beginning, he looked at it in the museum for a while, the bronze sword was very well preserved, not at all like the appearance of the ancient cultural relics unearthed in the Shang Dynasty, brand-new like a work forged without technology, what made him strange was that the sword was pitch black at that time, like it was plated with a layer of black metal, and he also laughed, the bronze sword is not cyan What is the bronze sword.

"When the time came to repair this sword, the people of the Chinese Academy of Sciences came. Professor Qiu looked at him with a straight gaze, as if asking what he thought.

"So this sword is not just as simple as damage, but also has a deeper meaning?"

Professor Qiu nodded, and when the experts studied the constituent substance inside, they found that there was a pitiful amount of copper in it, and it was replaced by an unknown substance.

"Frozen ground!"

When it comes to permafrost, the sea and the river become sensitive.

This shocked the people at the research institute, so they hurriedly took the samples and went back for further study.

According to Professor Qiu, when Wang Zhongheng of the Chinese Academy of Sciences went to see him, they probably hadn't found any connection between the bronze sword and the fossil.

He also looked at the bronze sword and didn't know how to start, the copper element was pitiful, and it was more of an ingredient similar to the attribute of "frozen soil", which was not only a matter of repairing ancient cultural relics, but also had high research value. In his years of experience, this kind of "frozen soil" similar material can destroy the original structure of objects, and at a deeper level, it is the arrangement structure of atoms.

"Can I ask you for something?" Professor Qiu said softly, but he couldn't hide the joy in his eyes.

The three of them looked at each other, and this strong old man was embarrassed.

Haichuan nodded, though he didn't know what was going on.

"Can you keep me a copy of your blood sample?" he asked tentatively.

Fang Jingxuan glanced at the professor, and then looked at Haichuan, what kind of requirement is this?

Haichuan was stunned for a moment, the abnormalities in his body couldn't even be found by the doctor, how could Professor Qiu find out, and he also wanted to find out the reason, so he agreed without much thought.
