Although Shen Wanqing couldn't directly ask the guards to put the box in the predetermined position, she had a way to quietly ask the guard to put the box in the position that Lin Yuan said. When the guards carried the box and passed by the predetermined position, Shen Wanqing naturally stepped forward, pressed the box with her hand, and said in half-baked German: "I'll help." ”

Where can the two guards let her help, and hurriedly excused herself, Shen Wanqing took advantage of the situation and said, "Just put it here, I'll just look for it." ”

This kind of armor-piercing bullet weighed forty kilograms each, and it was also laborious when the two guards carried it, and it was pressed by Shen Wanqing, and it was placed on the ground, the minister opened the box, and then stood aside with two guards, and Shen Wanqing pretended to look at it in the box.

Suddenly, I only heard Lin Yuan's exclamation from behind the shelf, and then everyone heard a "bang", and then saw the shelf staggering and fell down, but stopped halfway through, it turned out that someone behind grabbed the shelf, but the box on the shelf flipped over, and the shells inside fell, and everyone hurriedly hid to the side, and Shen Wanqing also dodged to the side, so that her back was facing everyone.

I only heard the sound of "dang", the cannonball above smashed on the cannonball below, and the protective paint coating of the cannonball below was suddenly smashed off a large piece, and the cannonball bounced and landed at Shen Wanqing's feet, Shen Wanqing screamed, squatted down, and covered her ankles with her hands.

Everyone suddenly realized: the falling shell injured Shen Wanqing, and hurriedly gathered around Shen Wanqing, Lin Yuan took the opportunity to come out from behind, did not look at Shen Wanqing, but squatted on the side of the shell, and said to everyone: "I'm really sorry, I got rid of your shells, you hurry up and take a look, if there is any damage, we are willing to compensate according to the price." ”

The minister said, "The damage to things is a trivial matter, so come and see this girl." ”

Lin Yuan walked up to Shen Wanqing and asked, "How is it?" ”

Shen Wanqing gritted her teeth and didn't speak, Lin Yuan said to everyone: "Then I'll take her back first, if your shell is damaged and needs to be compensated, I am willing to take full responsibility." ”

The minister asked, "But how could the shelf fall for no apparent reason?" ”

Lin Yuan said apologetically: "It's all my fault, when I was looking for it behind the shelf, something suddenly popped out, it seemed to be a mouse, I didn't watch out, I was startled, so I flashed back, I didn't expect to hit the shelf, I reached out and grabbed the shelf again, but I didn't expect the cannonball to fall." ”

The minister said, "Hurry up and let the girl take her hand away, and I'll see how the smash goes, do you want to go to the hospital?" ”

Lin Yuan thought to himself: "This is all Wanqing's acting skills, she will definitely not let the cannonball hit her, if I let her take her hand away, won't it be revealed all of a sudden?" ”

So Lin Yuan said: "Don't bother, I'll take her back, our mission has a doctor." ”

Everyone nodded, Lin Yuan picked up Shen Wanqing, walked out, and came to a place where there was no one, before putting Shen Wanqing down and saying, "Your acting skills are really good, I believe it." ”

Shen Wanqing smiled: "Of course, did you get something?" ”

Lin Yuan took out a small piece of tape from his pocket and said, "Look! Right here, I got it while they were around you, what about you? Did you get the shape and size data? ”

Shen Wanqing replied helplessly: "I really have no choice, they are always by my side, and I have never had the opportunity to take out the camera." ”

Lin Yuan said: "It's okay, I took a look at it, and I have already estimated the approximate size." ”

Shen Wanqing asked, "What about the situation inside the shell?" Can you determine whether an artillery shell is an armor-piercing blaster shell? ”

Lin Yuan nodded and smiled: "If it is an armor-piercing blasting projectile, there must be traces of the connector at the end of the bullet, and I have not found such traces, so I conclude that this kind of shell is just an ordinary armor-piercing projectile, not an armor-piercing blasting projectile." ”

The two returned to the post house while talking, it was already late at night, and only one room was still lit, Shen Wanqing asked, "Who is that room?" Why don't you sleep so late? ”

Lin Yuan said, "Let's go and have a look." As he spoke, he took Shen Wanqing upstairs together, and when he arrived at the door, he realized that this was Zhang Yuanyi's room, and Lin Yuan said to Shen Wanqing: "If my guess is correct, it must be Hilbert who came to find Zhang Yuanyi." ”

Shen Wanqing asked, "Who is Hilbert?" ”

Lin Yuan said: "It's the mathematician I told you." ”

As soon as Shen Wanqing heard the "mathematician", she immediately said: "Then you should go in by yourself, I'm going back to sleep." ”

As soon as Shen Wanqing left, Lin Yuan knocked lightly on the door, Zhang Yuan opened the door, and Lin Yuan asked, "Is Hilbert here?" ”

Zhang Yuanyi smiled and said, "Of course, he understood the process of proving my Riemann conjecture and came to chat with me." ”

Lin Yuan smiled: "Chatting, one of you doesn't know German, the other doesn't know Chinese, how can you chat?" ”

Zhang Yuanyi said: "Didn't I tell you several times? We mathematicians don't need words when we talk. Zhang Yuanyi walked into the room with Lin Yuan, pointed with his hand, and said, "Look at it." ”

Lin Yuan followed his fingers and looked at him, so surprised that he couldn't close his mouth, because the room was full of paper full of words, a piece of white flowers on the ground, and there was no place to stay, Hilbert sat on the edge of the table, and when he saw Lin Yuan coming, he hurriedly said: "You're back, great, I just have something to say." ”

Lin Yuan thought to himself: "How is it?" Shocked by our super-modern strength, you must want to come to work with us. But as soon as Hilbert spoke, Lin Yuan was taken aback, because Hilbert said, "I hope that Mr. Zhang can teach at our University of Göttingen!" ”

Lin Yuan heard this and thought, "I want to poach you!" How did you come to poach our people? Without waiting for Lin Yuan to speak, Hilbert spoke again: "As long as Mr. Zhang is willing to teach at our University of Göttingen, we can now grant him the position of tenured professor, this is not flattery, frankly speaking, his research on the Riemann conjecture far exceeds mine." ”

The University of Göttingen is the center of number theory research in this era, and there are many masters here, and Hilbert actually directly asked Zhang Yuanyi to be a tenured professor, which shows the importance attached to him, Lin Yuan smiled and said: "I will give you a better choice, you go to our China." ”

Hilbert shook his head again and again when he heard Lin Yuan's words, and said, "It's too far." ”

Lin Yuan smiled: "What are you afraid of, don't you want to investigate the truth of mathematics?" What is the secret of the non-trivial zero points of the Riemann function that are located on a straight line in the complex plane? Don't you want to find out? ”

Lin Yuan said exactly what Riemann conjecture was, Lin Yuan had met many scientists, and knew that their common characteristic was that they had a strong desire for the mysteries of nature, which was like a traveler in the desert who wanted a sip of water, so Lin Yuan used to explore the mysteries of nature to "seduce" him.

Lin Yuan saw that Hilbert's heart was moved, so he continued: "If you stay in Germany, I don't think your life will be very good, according to my observation, your status does not seem to be high, that day in the restaurant, an ordinary waiter can give you a look, if you come to me, you will definitely get the highest courtesy." ”
