Until the end of work, everyone didn't discuss the reason, Meng Zhang took the opportunity to invite the two to come back the next day, Chang'an agreed, there are indeed many things that the man in black doesn't understand.

Out of the Academy of Sciences, Shen Yu stood outside the yellow cordon and was not in a hurry to leave, Chang'an didn't know why, only heard Shen Yu sigh and said, "You, how many 'secrets' are there that I haven't seen?" ”

Chang'an was slightly stunned, his eyes flickered, and then he pretended to raise his head proudly and said, "What?" Think I'm amazing, right? As I said, of course it's true that I studied computer science. ”

Shen Yu shook his head and said with a smile, "Sometimes smart, sometimes ......"

"Sometimes what's wrong? People have always been smart! ”

"The statements made by the National Academy of Sciences outside are all true, but don't you think today's management is particularly lax?"

"It seems that Yangyang's ID card will be good and bad for a while, and there will be a look like they don't know about the image verification, and ......."

Shen Yu looked defeated, are these the main points? Don't want to think about why the surveillance building is so easy to enter? Why does Meng Zhang take everyone to visit the whole building? The computer in the main control room lets you operate it at will?

Meng Zhang warmly invited the two to visit tomorrow, but did not mention the identity verification card to enter the gate of the National Academy of Sciences. It's a completely unreasonable thing, haven't you thought about the reason?

"Here, you stand here and put your hand over the cordon." Shen Yu pointed to the cordon on the ground and said to Chang'an. Chang An stretched out his hand and shook it, and took a few steps forward, completely ignoring the existence of the barrier. "What? Nothing! What are you doing with your hands held so high? ”

The moment Chang'an's hand touched Shen Yu's fingertips, Shen Yu suddenly couldn't feel the existence of the barrier, and was brought into the barrier unimpeded.

Shen Yu has a feeling that the defense system within the Academy of Sciences is not defensive against Chang'an, and if other people need to be identified with identity cards, then Chang'an itself is a kind of identification, and it is also an advanced identification. Perhaps, Meng Zhang noticed it, so he spent the whole day verifying and testing this identification?

Retreating outside the cordon, Shen Yu picked up a stone on the ground and threw it into the yellow line, and the "pop" stone bounced back at the moment when it was about to pass over the yellow line.

Looking at Chang'an's surprised expression, Shen Yu said, "Now do you know why the Academy of Sciences is difficult to enter?" This invisible barrier is the key! ”

Chang An stretched out his hand into the air and felt it carefully, and after five minutes, he said, "It's a defensive network created by electronic energy...... At present, the main ways to pass are...... Chip certification. ”

"Do you understand this?"

"Of course, I said, I'm a computer student, and I'm particularly sensitive to this kind of electronic program, this barrier is actually just a layer of electronic induction system, this kind of energy induction network can't be seen by ordinary horizons, well, people like to define a name for this kind of invisible barrier, called 'enchantment'."

"With your explanation, the Academy of Sciences is not so mysterious."

"The National Academy of Sciences, the National Academy of Sciences, people research and believe in science, of course, there is a theoretical basis, but outsiders don't know it, and it spreads to be divine."

"Oh?"

"Look, we can see and hear each other now, but if you stay in a closed car, or in the house next to you, the car and the house will block my sight, hearing, and touch......"

“…… And the substance that hinders people's senses can be tangible or intangible, depending on the properties of this substance? ”

"Exactly! If you have the keys to your car and your house, or if you have permission from your owner, you can get through these obstacles unharmed, and if you don't, you'll be kept out. The same is true for the CAS system. ”

Shen Yu nodded and said that he was taught, people will always have all kinds of speculations and conjectures about the unknown, but they don't know that everything in the world has traces to follow and evidence to follow. However, why is Chang'an able to operate unhindered in the National Academy of Sciences? On what basis?

The next day, the two came to the National Academy of Sciences again as promised, and sure enough, they didn't even need a door card, so it could be said that it was truly unimpeded.

In addition to Meng Zhang and Wei Silu who greeted them in the main control room this time, there was another person, and under Shen Yu's prompting, Chang'an learned that this sixty-year-old man was the president of the National Academy of Sciences, Meng Zhang's father, and Yangyang's grandfather.

Dean Meng was a little excited to see Chang'an, "I didn't expect it to be you, Miss An." I listened to Zhang'er's report yesterday, and I guessed if it would be you, but I didn't expect it, I didn't expect it,......"

"Dean Meng, hello, have you seen me before? Did you recognize the wrong person? Not only Chang'an was puzzled, but everyone looked like they didn't understand.

"It won't be wrong, it won't be wrong, the old man may be dizzy, but this system can't be wrong, I've seen the monitoring you came in today, it won't be wrong!"

"Dad, don't get excited, sit down and say slowly, Miss An and Major General Shen are here to visit you today, what the hell is going on?" Meng Zhang hurriedly stepped forward to appease, it was rare to see the old man so emotional, but don't rush to make a mistake.

Dean Meng sat down and began to tell the story of many years ago, when Dean Meng was just an ordinary academician.

In that year, a wealthy man contacted the leaders of the scientific research institute through various connections, and proposed to build a new scientific research institute in another location to make some contributions to the national scientific research work.

Originally, this proposal was difficult to pass, but the other party proposed that it was enough to apply for the establishment of the project only in the name of the scientific research institute, and the scientific research institute would not pay a penny of funds, and if it was not satisfied after the completion of the project, the agreement could be terminated.

This is simply a pie in the sky, which is equivalent to giving it away for nothing, but what is the purpose of that person? Is it a hoax? The leaders hesitated, and it was not until the man invited an "authoritative person" and made a legal notarization to sign the donation agreement on the spot, and the plan was finally decided.

During the construction of the new hospital, the state put forward a plan to establish a new district in Jianyi, and the new hospital under construction has also become part of the plan.

Three years later, the Jianyi New Area was completed, and the project of the scientific research institute was completed.

The girl took everyone to visit the entire new institute, introduced the purpose of each place one by one, and proposed the security plan of the scientific research institute.

At that time, everyone thought that the girl's explanation was simply ridiculous: a unit engaged in scientific research bought 100,000 acres of barren mountains and wilderness to grow crops? What does a comprehensive surveillance and defense system have to do with scientific research? The direction of research in those specially set up laboratories sounds ridiculous.

If it weren't for the fact that she was sure that she was the investor in the construction of the new hospital, everyone would have gone long ago. The dean regretted his decision a little, this was a completely layman's institute, and it was a pity that such a good resource was lost.

In the end, the dean refused to sign the acceptance documents, which meant that all the liability for the loss of the project would be borne by the project investor alone.

The girl didn't seem to care about this, and a few days later, the girl asked Dean Meng for a long talk.

and handed Dean Meng two things, a gift agreement and a computer chip.

Dean Meng was skeptical about the content of their conversation, but still made some arrangements according to what the girl said.

On November 17th, a meteor shower changed the world, and when the virus swept the world, infected two-thirds of humanity, and polluted the land and water, until humanity truly fell into the catastrophe of the world, those present on that day realized what they had missed.

The chip is the core system of the National Academy of Sciences, and President Meng has become the only person who has the authority to open the system and authorize the new hospital.

Coupled with the gift agreement, the current Academy of Sciences can be said to belong to Dean Meng's private property, but in addition to serving as the president, he is more devoted to his own scientific research and makes more contributions to the survival and development of mankind, so as to live up to the good intentions of the mysterious girl.

Speaking of this, everyone suddenly realized that the National Academy of Sciences in Jianyi still has such a story, no wonder the National Academy of Sciences has never participated in the struggle of various forces.
