Li Tangshan soon found Professor Wang's laboratory, the door was closed, and through the glass on the door and window, he could see that the staff inside were busy coming and going. Li Tangshan rang the doorbell, and a medium-sized young man opened the door and asked, "Hello!" Is there anything you can ask about? “

Li Tangshan stretched out his hand and said, "Hello! I'm Li Tangshan, a new student, please take care of me! I'm here to see Professor Wang. “

The young man held Li Tangshan: "I'm Xu Xingning, you can call me Xiao Ning." Li Tangshan, Mr. Wang said that you, MIT top students are amazing! Come on in! Mr. Wang is in the dust-free laboratory, I'll take you there"

Xu Xingning asked Li Tangshan to put on a dust-free suit and wash the drugs. I took him to see Professor Wang, who was observing the wafer design under an electron microscope. Xu Xingning motioned to Li Tangshan to wait for Mr. Wang's free time, and then Professor Wang looked at the display data and said happily: "The new design doubles the communication transmission rate, Wu Changle, you kid is good!" Dare to think, dare to do! ”。 The young man named Wu Changle next to Professor Wang was grinning happily and giggling there. At this time, Xu Xingning said a few words softly to Teacher Wang, and Professor Wang turned around and walked over to Li Tangshan with a smile. Professor Wang is a very amiable scholar-type academician, tall and thin, with a pair of gold-rimmed glasses on the bridge of his nose and a talkative smile, giving people a warm and comfortable feeling.

Li Tangshan also hurriedly greeted him: "Hello, mentor! I've only contacted you at EMail before. My name is Li Tangshan, I just entered school today, and I wanted to visit you. ”

Professor Wang happily held Li Tangshan and said with a smile: "Li Tangshan, not bad!" I've read your graduation thesis at MIT and I have a lot of opinions! A few of you will come over and introduce your new classmate Li Tangshan. ”

Several people in the laboratory stepped forward to greet Li Tangshan, and soon returned to work.

Professor Wang called Xu Xingning over: "Xu Xingning, you take Li Tangshan to take a look around, familiarize yourself with the environment, and understand the rules and regulations of the study and experiment in the institute." Just take Li Tangshan Hospital to sign a confidentiality agreement. ”

Professor Wang turned his head to Li Tangshan and said: "You and Xu Xingning take a look, if you don't understand anything, just look for him, this kid is more enthusiastic and willing to help people, I still have a few sets of experiments to do here, and I will find time to communicate with you in the future." ”

Li Tangshan and Xu Xingning got out of the laboratory, and Xu Xingning, who was exquisite, completed all the relevant procedures in three clicks. Li Tangshan will join Professor Wang's experimental team tomorrow. Li Tangshan soon entered the campus life, and the main research direction of his mentor's team is basic research in quantum communication.

Quantum communication was first discovered by French physicist Alan Estpequor in 1982, and in 2012, Chinese scientist Pan Jianwei and others successfully achieved 100 kilometers of free-space quantum teleportation and entanglement distribution for the first time in the world, laying the technical foundation for the launch of the world's first "quantum communication satellite". Optical quantum communication is mainly based on the theory of quantum entangled states, and uses quantum teleportation (transmission) to achieve information transmission. According to experimental verification, no matter how far apart two particles with entangled states are, as long as one changes, the other will also change instantaneously. There will be a special chapter on quantum entanglement later, and I won't write too much here.

Professor Wang also pays special attention to Li Tangshan from MIT, and Professor Wang is also very satisfied with Li Tangshan's performance in all aspects of the team.

One day, Professor Wang called Li Tangshan out alone, and asked all the electronic devices on his body to be put in the isolation cabinet, and then took Li Tangshan to a separate conference room protected by two soldiers, where a row of elderly people sat at the conference table. After Li Tangshan studied at Beihang University, he saw this kind of lineup for the first time, and there were several old men wearing military uniforms wearing 7 horizontal badges and lemon yellow epaulettes, Li Tangshan studied the military uniforms of Chinese mainland and recognized them as leaders of the Central Military Commission at a glance.

"Tangshan, don't stand and come and sit together! I came to you today, that is, a few of our seniors to learn something about the situation with you, don't be nervous, say hello to a few seniors first" Professor Wang beckoned Li Tangshan to come and sit down.

Li Tangshan wondered if he had done something wrong in that place, which attracted the leaders of the Central Military Commission to question.

"Seniors, Tangshan greets you!" Li Tangshan still honestly said hello to the old-timers.

"Yes, young man, come and sit together, we old immortals want to ask you something, if you think it's convenient, just answer us truthfully. These things have a bearing on the future of the Chinese nation, and we sincerely hope that you will answer them truthfully. The old man in military uniform said very kindly.

"Hmm!" Li Tangshan nodded hurriedly.

"Young man, we have checked your family through many ways, first of all, we want to thank your family for their selfless dedication to China and the Chinese nation! We searched the historical materials and found that it records that your family is related to the inheritance of holy relics? Is there such a thing? As soon as the old man saw Li Tangshan's very embarrassed appearance, he already knew in his heart that Li Tangshan knew more than them.

"Don't worry, young man, we don't mean anything malicious. Let's tell you the truth, there is a 507 institute in our country, which was established under the auspices of Qian Xuesen's predecessors to study cosmic medicine, and with the development of quantum mechanics, all our theories under Einstein's general theory of relativity are no longer applicable. You are the old king who studies quantum communication, and you also know that there may be 2.5 space in quantum entanglement. This shows that there are many areas that we do not understand, and that science is constantly improving. At the same time, it also shows that we have the possibility to go back to the past. If we can go back in time, so can the Americans and the Japanese. I have received some information indicating that some right-wing groups want to erase the Chinese nation from history by changing the normal course of history. In this way, the Japanese and Americans will be able to dominate the world forever, and the Chinese nation may not exist. Young man, you should know the seriousness of this matter, so we would like to know more details about the relics. The old man in military uniform said very seriously.

After listening to the old man's words, Li Tangshan thought to himself: "This holy relic itself belongs to the entire Chinese nation, not our Li family. It seems that the manuscript can be true, otherwise how could it cause the Central Military Commission to intervene in this matter, my grandfather and Uncle Zhuo have always asked me to contribute more to the Chinese nation. Li Tangshan probably understood the ins and outs of talking to him, so he was much more relieved. Tell everything that can be said about the family inheritance, and tell them that the holy relics have been lost, and the last time they appeared was Meizhou, Guangdong. He didn't say a word about the appearance of the saint because he didn't know if it was true.

After listening to Li Tangshan's report, the seniors' faces became even heavier. The old people knew that this matter was tens of thousands of times more complicated than they thought. The expressions on their faces became more serious, and they discussed with Professor Wang for a long time.

The old man in military uniform from the Central Military Commission turned back to Li Tangshan and said, "Tangshan, since this matter is related to your family, we will discuss the result or be carried out by you." In addition, we have decided to recommend you to participate in the 507 Qian Xuesen temporary group internship qualification, but considering your nationality, you must compete with mainland students to qualify for the official internship. Tangshan, I hope to see you in 507, and I wish you a long way! Finally, the content of Tangshan's conversation today must be kept confidential! “

Due to the recommendation of the old-timers, Li Tangshan, as an outstanding student of the School of Communication, naturally appeared on the list of 507 projects.

Tutor Wang Wei told Li Tangshan that this year's selection will be more demanding than in previous years, the assessment will be stricter, and the number of places will be less.

Li Tangshan listened to Professor Wang's words, and was very worried that it would be difficult for him to pass the assessment. He himself wants to cherish these opportunities, as 507 is as mysterious as Area 51 in the United States, and mainly studies some superpowers.

During his studies at Beihang University, Li Tangshan deeply realized that students in Chinese mainland were originally the elite of the elite, and it was even more difficult for you to stand out among them, which was why Li Tangshan was worried that he would not be able to defeat other recommended students.
