No words can describe and describe this process, because it is a miracle in itself.

But Song Baicheng couldn't see this miracle, he looked at Xia Lei who was motionless, and a sneer appeared on the corner of his mouth, "Mr. Xia, can't you figure it out?" It doesn't matter, don't be reluctant, after all, this is a difficult math problem to solve. ”

But at this moment, Xia Lei glanced up at Song Baicheng and said lightly: "Don't measure me by your IQ, thank you." ”

"You ......" Song Baicheng was angry.

Xia Lei suddenly picked up the pen to solve the problem, and the speed was very fast.

Song Baicheng's eyes widened in disbelief. Then, his mouth couldn't help but open and couldn't close.

This is not just because of the speed at which Xia Lei solves the problem, but the problem itself!

This problem is the Riemann conjecture, one of the seven major mathematical problems in the world today!

This math problem is considered to be the pinnacle of 20 deeds of mathematics and one of the seven math problems in the world that the Clay Institute of Mathematics has bounced. It was born in 1859, and more than a century and a half have passed, and no one has unraveled it to this day. Its significance, its difficulty can be imagined. But now, Xia Lei is solving this epic problem at a speed that calculates how many "1+1" equals!

Before he came, Song Baicheng was still questioning Xia Lei's IQ of 298, but now he felt that in front of Xia Lei, he was like a little kid who had just learned to count. If Xia Lei is compared to a towering tree, then he is just a weed under this towering tree.

Ten minutes later, Xia Lei handed over the A4 paper with the contents written on the back to Song Baicheng.

Song Baicheng was still in a state of fugue.

"Okay, it's a bit difficult, but it's not as difficult as I thought. I've figured it out, but I don't think you understand. Ask the mathematician and let him tell you if I'm right. Xia Lei said.

Song Baicheng came back to his senses at this time, and he looked at Xia Lei with strange eyes, "That...... Mr. Xia, don't you know the origin of this question?"

Xia Lei gave Song Baicheng a roll of his eyes, "I'm not a mathematician who studies mathematics, I'm a military worker, and I'm good at machining and electrical engineering." Do you think I'm idle and have nothing to do to solve math problems?"

Song Baicheng's lips moved, and he wanted to say something but didn't say it.

"Alright, I'm going to work. Let's go. Xia Lei turned and entered the workshop.

The door to the workshop closes automatically.

Song Baicheng was stunned for a while before turning to leave. Now, there was no longer any doubt in his heart. Xia Lei is not the smartest person in the world, and the solved Riemann conjecture in his hand is a heavyweight proof. With this evidence, he could already draw a perfect end to his errand.

Moments later, a Hongqi sedan drove out of the Reimaa Arsenal and headed for downtown Kyoto.

"Mr. Z, Charleigh ......"

"What's wrong?"

He solved the Riemann conjecture. ”

"What Riemann conjecture?" Mr. Z's voice came from the phone.

"That's right, based on the data on Xia Lei's IQ in Fanfan's report, I asked a mathematician to find me a problem. The mathematician gave me this Riemann conjecture. It's been almost two centuries, and no one can unravel it, but he ...... It only took him ten minutes. Song Baicheng's voice was like sleepwalking.

There was silence on the phone for a moment before Mr. Z's voice came, "Are you sure he's right?"

"Eighty percent. When the mathematician gave me this problem, he also gave me some materials for other people's solutions, and there were some solutions to them. I have observed Xia Lei's problem-solving process, and some of the same content has appeared. Of course, the final result is for mathematicians to judge. ”

"Bring Fan Fan's research report and Xia Lei's Riemann conjecture solved by Xia Lei and let me take a look. ”

"I'm on my way, I'll see you later, Mr. Z. Song Baicheng put down his mobile phone, he slammed the accelerator, and the Hongqi car sped up on the road.

A few hundred meters later, a locomotive followed from a distance.

The rider on the locomotive is none other than Charley, who has solved the Riemann conjecture.

When Song Baicheng leaves the Reimama Arsenal, where will he go? This is what Xia Lei wants to know.

Although he has survived this crisis, he knows that this is not the end. As long as the ZN Bureau exists, it will pose a threat to him. He had to know more about the ZN Bureau, he wanted to know where the ZN Bureau was and what kind of people were in the ZN Bureau. Only by understanding the opponent can he defeat the opponent.

The locomotive is speeding down the road.

A distance of a few hundred meters, this is an absolutely safe tracking distance, even if Song Baicheng is more cunning than a fox and his anti-tracking ability is stronger than that of the agents of the 101st Bureau, he will not find that someone is following him behind him.

Xia Lei not only deliberately kept a distance of a few hundred meters from Song Baicheng, but also had a human skin mask on his face. The opponent is not only Song Baicheng, but also ZN game, he has to be careful and careful.

Jingle bells, jingle bells......

While the locomotive was speeding, Xia Lei's mobile phone suddenly rang.

Who's going to call at this time?

Xia Lei took out his mobile phone and glanced at it, and then answered the call.

"Brother Lei Zi, where have you been?" Fan Fan's voice sounded.

"I've got something to go out for, do you have something to do?" Xia Lei slowed down the car, controlled the direction with one hand, and answered the call with his mobile phone in the other.

"I want to talk to you, I'll go to the workshop to look for you, but you're not there. ”

"We'll talk when I get back, I'm driving. Xia Lei said.

"Okay, then I'll wait for you. Fan Fan hung up the phone.

Xia Lei put his phone away, but he was wondering in his heart, "At this time, what does she want to talk to me about?"

Song Baicheng is indeed more cunning than a fox, even if he does not find a stalker, he maintains a high degree of vigilance, and even adopts some anti-tracking measures. He drove around the city of Kyoto in a big circle before finally driving into a government compound.

Charley stopped his locomotive three hundred meters away.

The compound was unremarkable. There are armed soldiers standing guard at the gate, and behind the gate is a three-story office building, which looks like it was built in the fifties and sixties, and it is very old. The walls are covered with creepers, like a green coat in that office building. The courtyard of the agency compound is not large, but it is full of plants, and those plants are also very old, and the canopy of many trees is even above the office building, like a giant umbrella propped up on top of the office building.

Vines, big trees, such places can't be photographed even by spy satellites.

Xia Lei's eyes moved to the gate, and he saw a sign with the words "Kyoto City Meteorological Monitoring Center" written on it.

Such an agency compound, such an unpopular brand, even the residents who pass by every day will not look at it more, let alone ask about the weather in the next few days.

If there's a flaw in this place, it's just a heavily armed warrior standing at the door.

Is this the mysterious ZN Bureau?

Xia Lei got out of the car and pushed the locomotive forward slowly. His eyes were fixed on the old office building. Getting closer and closer, as he approached the gate, his left eye jumped slightly, and the walls of the building "melted" as quickly as snowflakes in the sun, and the space behind the walls came into his sight without concealment.

It was an office with staff and office equipment. The scene of the staff working seemed quiet and efficient. The equipment also seems to be very advanced, and it is not something that ordinary companies or institutions can have.

Starting from the third floor, then the second floor, and finally the first floor, it took him just three minutes to see through the entire building. Just as he was looking through the first floor, his gaze suddenly stopped in an office. At that moment, it was as if his head had been struck with a wooden hammer.

Song Baicheng stood straight in front of a person in that office.

This person Xia Lei is no stranger, and even has a deep friendship with this person.

This person is - Ling Hao!

Ling Hao's face came into view, and bits and pieces related to this character also surfaced in Xia Lei's mind.

Initially, Ling Hao came into his sight as a special assistant to the First Office, and Ling Hao also gave him a lot of help in his struggle with Mu Jianfeng and Ye Kun. During that period, he regarded Ling Hao as his friend, and even regarded Ling Hao as his brother. But now, it's all falling apart.

"From the very beginning of my exposure to ancient alloys, my dad warned me that someone was already eyeing me. Now it seems that the person my dad said at that time was probably Ling Hao. Xia Lei's heart was filled with mixed feelings.

Who else in this world can believe?

Men don't care about loyalty, just because the weight of loyalty is too low. A woman doesn't care about loyalty, just because she is not seduced enough.

This sentence will make most people disgusted and unable to agree, but it is a true portrayal of the real society.

However, compared to the damage caused to him by Liang Siyao and Shentu Tianyin, the damage in front of him was nothing to Xia Lei.

Xia Lei's gaze locked on Ling Hao and Song Baicheng's lips, and while using lip language interpretation to interpret the conversation between the two, he slowly pushed the locomotive and walked.

"Mr. Z, this is the research report, and the Riemann hypothesis that Charley solved. Song Baicheng handed the document bag to Ling Hao.

Ling Hao opened the file bag and took out all the contents inside. He first looked at the Riemann conjecture that Xia Lei had solved.

"Mr. Z, on the way here, I took a picture of the Riemann hypothesis that Xia Lei had solved, and sent it to the mathematician who helped me. He saw it, and he said......"

"What did he say?"

He said it was a miracle of mathematics. Xia Lei solved this mathematical puzzle in the simplest way possible, which no one has been able to solve for nearly two hundred years. He also said that we should publicize this matter to the public, so that our country's mathematical community can raise its eyebrows in the world and achieve the highest glory. ”

"Shut him up. ”

Song Baicheng said: "I have warned him that he will not speak out without our permission." ”

"No wonder what he can achieve, IQ 298...... But I always feel that things will not be answered so simply, what is the problem?" Ling Hao looked out the window and muttered to himself, sighing.

At the same time, at the gate, the soldiers with loaded guns suddenly scolded Xia Lei, who was walking slowly with a locomotive: "What are you doing?"

Xia Lei followed and retracted his gaze, and he accompanied a smiling face, "Dude, I'm sorry, my car suddenly turned off, probably because the spark plug was stuffy." ”

The warrior said coldly: "Don't look around, get out of here quickly!"

"Okay, okay, I'll go right away. Xia Lei quickened his pace.

Although he was murdered by this warrior, the gain this time was huge.

He found the headquarters of the ZN Bureau.

He learned Mr. Z's identity.
