Chenli from a mountainous military prison, day 36. The white ball was about to run out of energy and went into a dormant state, and Li Xianhui had no choice but to act alone.

"Master Jun, is there any important news recently?" Li asked the soldiers who came to deliver meals every day.

Today's meal has changed from mung bean sprouts to soybean sprouts, of course, without any oil and water. Li Xianhui looked at the food, although it was difficult to swallow, but in order to survive, he had to swallow a few bites.

"Hey, what else can there be, the country of Qi is starting to block technologically. It is forbidden to export technology to Xi State. The soldier said.

"Is it a big impact?"

"How do I know that?"

"Give you a chance once and for all, as long as you can recommend me to your superiors that I am a math genius, and I will take care of you for the rest of your life."

"Cut, are you crazy? I'm a math genius, but I'm still a physicist. The soldier looked at the dirty Li Xianhui with disdain.

"Master Jun, don't believe it, or you find a current problem in the mathematical world, I will solve it, you will publish it, if it is done, the name is yours, you just need to help me recommend it." If you can't solve it, you can take the head. ”

"What's the use of asking for your head, but if you can really figure it out, I'll have a reputation."

On the second day, the soldiers delivered the meal on time and brought a math problem transcribed in Xi Wen.

Li Xianhui took the question, read it carefully and found that it was the Hodge conjecture on the earth, and Xinhui was secretly happy in his heart, which had been solved by applying boron-based mathematics as early as 7 years ago. Then he said:

"Bring a pen and paper, the more paper the better."

After the army brought pen and paper, Li Xianhui began to calculate, because Chenli's mathematical foundation was relatively weak, Li Xianhui had to make a lot of assumptions and proofs. For about an hour and a half, Li Taohui deduced dozens of pieces of paper.

"Master Jun, take it, this is a very rigorous Hodge conjecture paper. Don't forget to recommend when you become famous. ”

The soldier took the calculation paper, although he couldn't read it, but seeing that Li Xianhui was so confident, he didn't dare to slack off, walked out of the prison quickly, and went straight to the officer barracks. How dare the soldier who delivers food be greedy alone, he gives the calculation to the leader of the garrison, Barry.

"If there are really two clicks, but you still need to verify, you keep a backup copy, and transfer the original to the higher level for them to handle." Barry said.

Li Xianhui's calculus was delivered step by step, and finally handed over to Midden, the best mathematics laboratory in Xi State.

Midden took the draft of the calculation, and without understanding it for a moment, he said, "Let me have a day." ”

Before waiting for the next day, Bai Rui received a notice from the higher-ups: "Requisition military spy Li Xianhui." ”

Bai Rui did not dare to slack off, and personally went to the underground prison, invited Li Taohui out of prison, and arranged a bath and a sumptuous feast for him.

"There's a request, I'm going to carry the white ball with me."

"Okay, it's up to you. It took a lot of effort to recommend me, so don't forget to say a few nice words when you go to Chief Carter. "Beri, please.

"Master Jun, don't worry. But there is one thing I want to take, I want to take the white ball. Li Xianhui smiled. After that, he followed the leading soldiers to bathe and eat.

"Okay, that's easy. You go to the bath first. I told my men to prepare. ”

After packing up, Li Xianhui followed a soldier to board a military vehicle shaped like an Earth SUV, and saw that Bai Qiu was already in the back seat.

The military vehicle was launched, drove for about 6 hours, and entered a small city. The city is well built and the buildings are neat, far from the strange buildings in the Proxima Centauri Super Ring-star aircraft carrier.

"Master Jun, the environment in the small town is good." Li Xianhui accosted.

"You're right, this is an ancient city, but it's a pity that you can't see it on this road."

"If you can't see it, let's bother to tell the story of this city."

"It is said that as early as 3,000 years ago, in the southwest of Xi country, that is, here, there was a super flood, the water has been pouring from the sky, the flood forced the local creatures to move to the mountains behind them, but the flood did not have the meaning of retreating, constantly flooding the mountains, and finally hundreds of thousands of creatures were forced to the top of a mountain, and they were about to be swallowed by the flood, but they saw the sky shining brightly, a goddess fell from the sky, blocking the sky under the water, and then waved his hand, and the flood receded.

The goddess did not leave after the flood receded, she taught the local Chenli people medical skills, dispelled the plague, taught agricultural planting, etc., and after a few years, the goddess saw that agriculture was prosperous and the population was gradually prospering, so she quietly left. ”

"I guess it's not a god, it's a higher level of intelligent civilization."

"You're too good at, aren't you?"

"What is this military vehicle used for?"

"Food driven."

"Grain? You mean fuel made from grain? ”

"Yes, food becomes fuel."

"What about the helicopter that arrested me more than a month ago? Wouldn't it be faster to send it to me? ”

"The country has long been provoking on the border, and all the high-level equipment has been transferred to the front line and is ready to go to war at any time." The soldier said impatiently.

The military vehicles left the city and rushed to the suburbs, and Li Xianhui estimated that it was a civilian airport. Along the way, the mountains are gentle and the vegetation is lush, and at this time, Chenlixing is in the humid cycle of the big cycle, and agriculture is flourishing, so it is no wonder that alcohol can be used as fuel for the production of grain.

Sure enough, the military vehicle ended up at a civil aviation airport.

Several soldiers in serious costumes and drivers completed the handover, and then guided, Li Taohui entered the special waiting room, and the fat boy was picked up and presumably consigned.

While waiting, Li Xianhui wanted to talk to get some information, but the soldier was too serious, and there were no extra words except for a few yes. Li Xianhui had no choice but to give up and wait for the plane. The airport was too small, and I waited for half an hour without seeing any planes landing.

When I was bored, I saw a jet on the runway of the airport that was far inferior to the middle of the 20th century on Earth.

"It's better than a propeller plane." Li Xianhui said secretly.

After flying for nearly 4 hours, Li Xianhui finally met Shangdu, the economic and political center city of Xi State.

In the northwest of Shangdu, in the highest military command center of Xi State, in a conference room, Li Xianhui and two soldiers were waiting in the room. After a while, a capable female officer appeared.

"I've heard you're good at math, but your background is a mystery. Before you gain trust, it can't be ruled out that you are a spy of the country, so your personal freedom is still restricted, you have no problem with that, right? Jie Liya, deputy general staff officer of the Xi army, said.

"No comment, but how can I gain your trust?"

"Here are the top math questions from Xi Guo, a total of nine, the time is up to you, and you can refer to any reference book, all the correct answers can only prove your mathematical talent, and the follow-up assessment will not let you know." Teriya said and took out a stack of exam questions and put them in front of Li Xianhui.

Li Xianhui quickly flipped through the questions and found no problems.

"Give me two hours." After that, Li Xianhui quickly calculated. Jieliya stared at Li Xianhui intently, she liked the way Li Xianhui solved the problem seriously.

At an hour and ten minutes, Li Xianhui submitted the paper ahead of schedule.

Teriya was surprised, because when he came, several mathematicians from Xi estimated that it would take at least half a month for Li Xianhui to be able to solve all the problems.

"Please take Li Xianhui down to rest." Terriya instructed the soldiers behind Li Xianhui, and then hurried away.

Fei Sheli, the most influential mathematician in Xi State, and even the mathematician who is unsurpassed by Chen. Teriya was a student of Feselly, and she left Li and went straight to Fisher's place of work.

Fiscelli was immersed in revising the student's thesis, and when he saw Teriya hurrying in, he immediately understood: "The answer is finished?" ”

"Well, a genius that God will envy."

"Yo, even you have such an evaluation, it seems that you can't be wrong, give me the roll."

Fiscelli took it, studied it carefully, and from time to time did the math himself. Fiscelli did not expect that these problems could be solved in this way, and many hypotheses and their proofs completely opened up another world in the field of mathematics. He was awarded the treasure and studied for 2 hours without distraction, forgetting that his student Teriyah was still there.

"Look at me, I'm so serious that I forgot about you. I would like to come to a conclusion first, this person is by no means a spy of the country, because his mathematical thinking is by no means something that Chen Li can think of, I just followed his train of thought to calculate the first problem, and found a broader new field of mathematics. If this person is willing to be used by me, it is really a godsend, if he can't be used by me, he must not be allowed to get it. Fix it if necessary to prevent future problems. ”

"Remember, students."

"You go back first, I'll try to finish my study tonight, and I'll give you an answer tomorrow."

After more than a month of prison life, Li Xianhui was tired early, and after returning from answering the questions, he fell headlong and prepared to have a good night's sleep, so he went to bed early, showing his confidence and calmness.

In the early morning of the second day, Li Xianhui was woken up early, had a hasty breakfast, washed up, and was once again invited to the conference room where he answered the question yesterday, but at this time there were already people waiting here. They were Teriya, Fischer and the Chief of the General Staff, Homanitz.

"You are the math geek who claimed to have traveled from 800 years ago to avoid the extinction of Chenli, Li Xianhui?" Homanitz asked.

"You don't believe it anyway."

"Putting aside how ridiculous it is to traverse, I just want to ask where did you get your math ability?"

"If you want to use me, you shouldn't communicate with me in an interrogative tone." Li Xianhui deliberately pretended to be angry.

Homanitz was about to retort, but was blocked by Fischer.

"Young man, I admire your talent, I haven't slept all night, I was shocked by your mathematical ability, you can't help but solve mathematical problems that have plagued you for many years or even centuries, and you have also expanded countless new fields of mathematics, these new fields will definitely become the cornerstone of future science and technology, today I will not discuss your origins, I just want you to have an attitude, are you willing to help us Xi Guo against Qi Guo?" Fiscelli asked.

"How to resist the blockade and threat of the country, and let your country surpass the country, I have already had a countermeasure. But I would like to meet your head of state. "Li Xianhui struck while the iron was hot.

"The Führer is what you want to see!" Homanitz said.

"Then, please forgive me for not feeling well, and go back to Rand Heights Prison."

"Young man, don't worry, I'll coordinate the matter of the Führer. As long as you are willing to help Xi Guo, everything is negotiable. I'm going to coordinate now. Fescheri got up and left.

The only room left in the conference room was Homanitz and Terria and Li Xianhui. Jie Liya didn't say a word from beginning to end, just stared at Li Taohui, as a mathematician with deep mathematical attainments, she admired Li Taohui's mathematical talent.

Not long after, Fiscelli came back and said to Li Xianhui: "You can see the Führer in the afternoon." I'll go with you then. ”

In the center of Shangdu, behind a huge circular square, a simple red building is the seat of Xi's highest decision-making body.

Xi did not implement democracy for the whole people, but a centralized democracy based on its more than 1,000 years of patriarchal system, that is, the whole country according to virtue and prestige, elected 12 veterans, the patriarchs can be re-elected for life, the patriarchs recommend the country, and when making decisions on important events, the patriarchs and the heads of state make joint decisions, and the heads of state shall not abuse their power without the authorization of the council of senators.

Li and Fei Sheli were guided into the Hall of the Senators. It may be that the elders have just finished a meeting, and all 12 elders are there.

The Führer was standing in front of the temple to greet him.

"I am Robesman, the head of state of Xi State, Mr. Li Taohui, please accept my invitation to participate in important national policy meetings on behalf of Xi State." After that, he picked up Li Xianhui's hand and put it on his right cheek, which is Xi's highest etiquette.

Li Xianhui was favored and didn't know how to return the gift, so he looked at Fei Sheli and asked for guidance.

"You just have to do it the same way." Fiscelli prompted.

After some etiquette, Li Xianhui and Fei Sheli entered the meeting hall of the senators.

"Straight to the point, I look forward to Li Xianhui's teaching." Before Li Xianhui could sit down, Robesmann couldn't wait to ask.

"First and foremost, to solve the current technical blockade and plant rust problem, my technical reserves are enough to deal with it, if everything goes well, it will only take 3 months to solve it.

Second, it is necessary to solve the medium-term energy and residential problems. I will use new technologies, use emerging energy, and increase social wealth through new technologies, so that the residents of Xi can be rich.

Finally, for long-term prosperity, the first is to change the existing patriarchal system. The second is to develop education.

If the Führer thinks it is possible, please send an assistant, and I will prepare a detailed plan for Xi Guo. ”

"Yes, sir, if you need anything, just say it. I will support it with the whole country. Führer Robesmann said firmly.

The 12 elders also appeared to unanimously support Lee's strategy as never before.

Three months later

Li has completely eliminated the problem of grain rust through genetic modification technology. At the same time, we will survey underground oil and gas resources, and use new technologies to realize that oil and gas fuel is 90% cheaper than grain fuel.

At this time, the border environment was more and more solved by rust and fuel, and the state of Xi was considered a huge threat, and the war situation was even more severe.

The Führer came again to ask for advice, and Li had to think of nuclear energy.

After more than a month of overcoming difficulties, a small equivalent *** exploded successfully in the southern sea of Xi State, Quan Chen left, and was stunned by the mushroom cloud rising high, of course, including Li Taohui, he was worried that he would release a devil.

The deterrence of the state of China shook the government and the opposition, and then gradually withdrew under the pretext of peace talks, and the tension on the border eased.
