　　At this point he was surrounded by a group of mathematicians.

　　"Qiu, why don't you let Professor Zhang talk about Riemann's conjecture?"

　　"That's right, the greatest mathematical discovery of this century was just missed by us."

　　"Are you a sinner to do math?"

　　A group of mathematicians began to count Qiu Chengtong's fault.

　　Standing there, Qiu Chengtong couldn't help breaking out in a cold sweat.

　　Heaven and earth conscience, how could Zhang Wei listen to him?Letting him control what Zhang Wei said would be difficult for a strong man.

　　It's just that he has become a sinner in the mathematics world at this time, so that he doesn't know what to say for a while.

　　At this time, the other bosses immediately gathered around when they saw the movement here, "Professor Qiu, what are you doing?"

　　Qiu Chengtong suddenly smiled, "Professor Zhang said before that he prepared two topics for this lecture, one of which is the concept of gravitational waves today, and the other is the Riemann conjecture that has plagued mathematics for 160 years. It's all my fault now, why didn't I persuade Professor Zhang to talk about the Riemann conjecture."

　　Hearing this, a group of physics bigwigs suddenly quit, "Why don't you talk about gravitational waves? Compared with gravitational waves, although the Riemann conjecture is equally significant, it is still slightly less practical, right?"

　　This time the mathematicians stopped doing it, "Riemann's conjecture is slightly less practical? Do you know that there are at least thousands of conjectures based on Riemann's conjecture. Once the Riemann conjecture is established, then these thousands of The conjecture can be established, isn't this kind of significance as great as gravitational waves?"

　　The physicists immediately shook their heads: "What about the thousands of conjectures? Today, Professor Zhang is not only talking about gravitational waves, but also pioneering a new concept in physics."

　　"Yes, this concept of physics is comparable to the theory of relativity, and it directly guides us to space. Human beings are likely to open the interstellar era."

　　As soon as these words came out, the mathematicians were at a loss for words. They also listened to Zhang Wei's lecture and knew that the other party was right.

　　Just let them admit that the Riemann conjecture is not as important as gravitational waves, but that is absolutely impossible.

　　Seeing that these experts were red-faced, Qiu Chengtong hurriedly interrupted: "Everyone, everyone, don't worry, there is a chance, there is a chance, Professor Zhang will definitely talk about Riemann's conjecture in the future, but it's just a matter of time. Yes, principal, what do you have to do with me?"

　　When Lawrence heard the words, he immediately said: "Just now everyone wanted me to contact Professor Zhang, hoping to visit him..."

　　Hearing this, Qiu Chengtong couldn't help laughing bitterly, "I can help you convey this, but I don't dare to say if it can be done."

　　In fact, based on Qiu Chengtong's understanding of Zhang Wei, the other party is likely not to agree, but it is not easy for him to explain directly at this time, what if Zhang Wei really agrees?

　　Immediately, Qiu Chengtong took out his mobile phone and called Zhang Wei under the watchful eyes of the big guys.

　　After a long time, the phone was connected.

　　"Professor Qiu, what's the matter?" Zhang Yingxue answered the phone.

　　Qiu Chengtong suddenly said: "Academician Zhang, that's right. There are many scholars here who want to visit Professor Zhang. I wonder if he is convenient?"

　　Zhang Yingxin said apologetically: "I'm so sorry Professor Qiu, we have just left Harvard."

　　"Leave?" Qiu Chengtong asked in surprise.

　　"Yes, we've been at Harvard for so long, it's time to leave."

　　This time Qiu Chengtong was in a hurry, "Where are the two going next?"

　　"We haven't thought about this for the time being. At present, we are only sure to go to California. More specific details may not be known until California."

　　Qiu Chengtong didn't know what to say, and finally he could only say 4.4: "I wish you two a happy time."

　　Hanging up the phone, he suddenly looked at the big bosses who were staring at him with a wry smile.

　　"Professor Zhang is no longer at Harvard."

　　"Not at Harvard anymore?"

　　The answer was beyond everyone's expectations.

　　"Then where did he go?"

　　"California."

　　"California is so big, where did he go?"

　　Qiu Chengtong only shook his head.

　　"I don't know that."

　　All the big bosses sighed in unison in disappointment.

　　If they miss such an opportunity, they are doomed to regret for the rest of their lives. .

Chapter 282, Disappeared out of thin air

　　With Zhang Wei's departure, Harvard University slowly returned to its former tranquility.

　　However, on the Internet, the discussion about Zhang Wei has just begun.

　　Zhang Wei's lecture made countless people who didn't know anything about him really understand him.

　　Although he has achieved many achievements before, for the distant Americans, those are too unreal, and through this lecture, they really feel Zhang Wei's excellence.

　　NBC's live broadcast further expanded Zhang Wei's influence and finally locked in a 28% audience rating, which is a miracle in the history of the United States.Except for the annual Super Bowl live broadcast, no other program in the United States has achieved such popularity.

　　And the one who created this miracle is still a Chinese. It has to be said that it is a miracle among miracles.

　　For a while, Zhang Wei was talked about everywhere on the US Internet.

　　Some even quickly formed a fan group for Zhang Wei.

　　To the surprise of 10 people, many well-known scholars have joined this fan group. All of this shows the greatness of Zhang Wei to the world.

　　However, what frustrates Americans the most is that since the Harvard lecture, Zhang Wei has completely disappeared from the public eye, and no one knows where he went.

　　These days, Harvard University's phone has almost been blown up, and countless people have called to ask about Zhang Wei. Among them are scholars from all over the world, Zhang Wei's admirers, and the U.S. government.

　　That's right, since Zhang Wei left Harvard, the U.S. government has been lost. Zhang Wei, who was originally under strict surveillance, has disappeared out of thin air, which makes them unbelievable.

　　But the fact is that Zhang Wei really disappeared from under their noses.

　　Naturally, they didn't know that Zhang Wei had a jammer that could block all unnatural frequency bands.

　　There is such a thing, no one can find Zhang Wei's whereabouts.

　　So at this time, Zhang Wei and Zhang Yingxue were sitting on Xiaojiu, driving very comfortably on the interstate highway in the United States.

　　Admiring the beautiful scenery along the way, Zhang Yingxue couldn't help cheering.

　　And beside them, there was only a disguised Little Eight.

　　In fact, not only Xiao Ba has been disguised, but even Zhang Wei and Zhang Yingxue have gone through a certain disguise. If they are not particularly familiar with them, they will not be recognized at all.

　　With the help of jammers, they played freely all the way, not afraid that someone would disturb them.

　　Only in this way, the U.S. government can't help but be anxious.

　　At the CIA headquarters, the intelligence minister looked at the deputy ministers with incomparable seriousness.

　　"I think I don't need to remind me about the importance of this Zhang Wei?"

　　Several deputy ministers nodded in unison.

　　"Then who of you can tell me now, man? Where?"

　　Several deputy ministers could not help but wipe their sweat.

　　After a moment, a middle-aged woman said, "We have checked all the monitoring of the hotel, and we did not see the other party leaving the hotel."

　　"And we tracked the security personnel who were left at the hotel and we didn't find any connection to the target, and it seems they were looking for the target."

　　"At the same time, we have checked all the surveillance from the hotel to the outside of the city within a few days, but we have not found the other party's figure."

　　"In addition, according to our eyeliner report, the other party did not appear in the embassy."

　　After hearing this, the intelligence minister frowned even more, "So you want to tell me that a big living person just disappeared out of thin air?"

　　Several deputy ministers looked embarrassed, but the fact was that Zhang Wei really disappeared out of thin air.

　　"Look, you must find the person for me, and I must have news of him within 48 hours, otherwise you will just wait and resign with me."

　　Several deputy ministers couldn't help looking at each other, and then assured at the same time: "Please rest assured, we will find someone within 48 hours."

　　As old officials in the officialdom, they all knew that if they couldn't find Zhang Wei this time, they couldn't help but even the minister couldn't handle it, so they had to find each other.

　　Just when the CIA headquarters held an emergency meeting for Zhang Wei, at the US presidential palace, the US head of state was also asking about this.

　　"Has the Chinese man not been found yet?"

　　The Minister of Defense shook his head when he heard the words.

　　"not yet."

　　"Could the other party be transparent? Does your CIA not even have any clues?"

　　The Minister of Defense couldn't help but smile bitterly, "To tell you the truth, we are also wondering where the other party has gone, but we don't have any clues or clues yet."

　　"Then you say it's possible that the other party has left the country?"

　　"It's almost impossible," said the Secretary of Defense after a moment of thought.

　　"We have set up an extremely tight defensive line at the border, and it is impossible for him to get out."

　　"And the other party came to the United States for the reason of a scholar's visit. If you go back to China without going through the U.S. customs, it will cause great controversy. This is definitely not what the Chinese government wants to see."

　　"Even so, what about the other party?"

　　The Minister of Defense... In fact, he also wanted to know at this time, where is this Zhang Wei.

　　In fact, at this moment, not far from the White House, a young man and woman were walking leisurely.

　　"This is the presidential palace of the United States, and it's actually nothing special."

　　Zhang Wei shrugged and said.

　　Zhang Yingxue couldn't help but rolled her eyes playfully, "You are really cute!"

　　Zhang Wei suddenly smiled, "What's the point of life without skin!".

Chapter 283, the elusive Zhang Wei

　　Regarding Zhang Wei's bad taste, Zhang Yingxue was speechless for a while, but she still had some doubts.

　　It is said that Zhang Wei has always been afraid of trouble, so he should not deliberately make a detour from California to the Presidential Palace of the United States for the sake of skin.

　　"Little brother, do you have other reasons for coming here?"
