On the 36th floor of the Huanyu Building, Du Yu's president's office received a report from He Qian'an, the manager of the personnel department in charge of delisting, and Du Yu was taken aback.

Calling Mo Rufeng last night, Du Yu had already prepared that the Mo family would use official connections to hinder the delisting of Huanyu Group, but he didn't expect that the delisting would be so smooth.

"According to the feedback from the Shangdu Exchange, after we submitted the application for delisting, Secretary Yang of Shangdu No. 1 paid personal attention, and this morning the relevant institutions in Shangdu gave us a reply and allowed us to delist, and the procedures have been completed. From now on, Huanyu Group is no longer a listed company. He Qian'an, the manager of the personnel department, said in a deep voice.

Du Yu suddenly felt that there was something abnormal in this, but this was a good thing for Huanyu Group, and Du Yu immediately stopped paying attention!

Du Yu came to Huanyu Group today to ask the technical department to improve the security system of Huanyu Building and optimize the office system.

According to Du Yu's order, the parking lots on the third and second basement floors of Huanyu Daxia are temporarily open to the public.

The employees of the Huanyu Building can only park in the parking lot on the first basement floor, and Du Yu needs to place three Tianhe-9 supercomputers on the third basement floor, and today the Phoenix Base will escort three Tianhe-9 supercomputers to Huanyu Daxia!

The third floor underground has been listed as a forbidden place by Du Yu!

Huanyu Group, only Du Yu can enter, and the only authority of the access control system is only Du Yu's highest authority.

The executives of Huanyu Group are not eligible to enter the third basement floor!

Because of the three basement floors, it has completely changed!

First arrange the important things of the group for a day, and Du Yu took the elevator directly to the basement floor!

The elevator of the Universal Tower has been modified and no longer leads directly to the third basement floor and the second basement floor!

If you want to enter the second and third basement floors, you need to take the elevator separately!

And ordinary executives are not eligible to enter the second basement floor!

Du Yu came to the second basement floor, and then came to an elevator.

After entering a 36-digit complex password, you will also need to go through a number of most advanced security certifications in the world, such as fingerprint verification and pupil verification!

Then the elevator opens!

Step into the third basement floor and the place has changed dramatically!

Among the three underground floors, the machine Qì people brought back by Du Yu from Cangnan Star have completely rebuilt the three underground floors, and they are all high-tech alloys.

And these alloys are all made by Du Yu to let the space god worm directly bring the raw ore from all over the world to the Hope nuclear submarine, and convert the nuclear submarine into an undersea base and refine it!

These days, the space god worm has not stopped, and has been running around for Du Yu, shuttling around the earth, digging raw ore directly from the depths of the ore vein, and then staying until the Hope nuclear submarine, with the help of the powerful energy provided by the miniature nuclear reactor, refining the ore.

At this moment, Cang Nan reminded Du Yu!

"Master, the Fire Phoenix Commando has escorted three Tianhe-9 supercomputers from the Phoenix Base and are heading towards Universal Great Xia. ”

Immediately, Cang Nan also transmitted the image to Du Yu's mind.

The three underground floors are isolated from all radio signals, and only Cangnan can communicate with the outside world by using neutrino communication.

Several huge network fiber optic cables have been placed on the ground!

As long as the Tianhe-9 supercomputer is transported here, it can be plugged into the network fiber optic cable.

Shangdu is an international optical cable gathering place, and the network speed here is the best in China.

In fact, Du Yu could have used the guò neutrino communication instrument to convert network signals without network fiber optic cables, and he could also have three Tianhe-9 supercomputers to obtain network connections with the outside world, but in that case, the neutrino communication instrument would be exposed.

Moreover, the Honghuang headquarters sold three Tianhe-9 supercomputers to Du Yu, and it will definitely not be completely laissez-faire, Du Yu is sure that the Tianhe-9 supercomputer will definitely leave a back door.

In this way, Du Yu can only rely on network optical cables to obtain network connections with the outside world.

As for the system backdoor and hardware backdoor, it is impossible to hide from Cangnan.

It didn't take long for several large trucks to drive directly into the second basement floor.

Du Yu stood on the second floor of the basement and looked at the Fire Phoenix Commando who jumped from the truck.

This time, three Tianhe-9 supercomputers were escorted, and Ling Qingxuan, the captain of the Fire Phoenix Commando, and Colonel Feng Lie, the instructor, personally led the team.

"Captain, instructor, I didn't expect you to send it over in person, how embarrassing it is!"

Du Yu first saluted Ling Qingxuan and Feng Lie with a very standard military salute, and after putting down his hand, he grinned.

"I didn't expect you to become a local tyrant on the rich side in a blink of an eye, and we hope that you will take you in when we change jobs in the future. Feng Lie was joking with Du Yu.

"Colonel Feng Lie, since you talked about this, I really have a matter. I believe that there must be some demobilized special forces in the army, you introduce them to me, let them come to Huanyu Group as security guards, I give you the best treatment in China. As you may know, Huanyu Group is positioned as a high-tech enterprise, and hostile companies will definitely be indispensable in the future to spy on intelligence. ”

Since Du Yu acquired Huanyu Group, he had this idea in the Phoenix base, but he had not completely controlled Huanyu Group at that time, so he temporarily put it down.

Now, Du Yu completely controls the Huanyu Group and is not satisfied with the security department.

The vast majority of the security guards of the security department of Huanyu Group are just ordinary retired soldiers, and they are definitely not as good as these elite special forces who have been transferred from special forces.

And Du Yu believes that with their professional qualities, they will definitely make up for the loopholes in the security department of Huanyu Group.

Hearing this, Feng Lie suddenly fell silent, and at the same time, several Fire Phoenix commandos kept signaling to him.

Seeing this scene, Du Yu felt that there was a play.

"There was once a member of our Fire Phoenix Commando who was injured and transferred to another job, but he just couldn't go to the battlefield to fight, but if he was to be a security guard, it would be more than enough. And in the army, he is proficient in security work. Before coming to the Fire Phoenix Commando, it belonged to the internal security department. Feng Lie said with a smile.

"Chief, you're not sure what to say, so I'm sure this commando has a weird temper. You give me his contact details and I will contact him, and if he wishes, I will naturally welcome it. If he doesn't want to, I don't force it. Du Yu said with a smile.

"Unload the Tianhe-9 supercomputer first. Ling Qingxuan, who had never spoken, commanded crisply.

Immediately, the Fire Phoenix commandos helped the scientific researchers of the Phoenix Base to unload the Tianhe-9 supercomputer on the second underground floor!

When it was over, the Fire Phoenix Commando team left.

After the Fire Phoenix Commando Team left, Du Yu and the Jiqì people worked together to transfer the three Tianhe-9 supercomputers to the third underground floor!

On the third floor of the basement, three Tianhe-9 supercomputers were debugged, and Du Yu plugged in network cables for them.

One in Shangdu is the Shangdu Branch of the Ministry of State Security.

Because Shangdu is extremely important to Huaxia, not only is the Phoenix organization stationed here, but the Shangdu Branch of the Ministry of State Security is even more proficient.

In addition, the flood famine is in the Shangdu branch, and there are also strong people who have entered the sainthood.

The Shangdu Branch of the Ministry of State Security, at this moment, information appeared on the screen.

"The Tianhe-9 supercomputer has been plugged into the network fiber optic cable, and the guò network fiber optic cable is connected to the network. ”

"Open the back door and monitor the Tianhe-9 supercomputer. ”

But suddenly, the system backdoor and hardware backdoor on the Tianhe-9 supercomputer, including all system vulnerabilities, all disappeared!

Suddenly, the Shangdu Branch of the Ministry of State Security lost its monitoring of the Tianhe-9 supercomputer!

Immediately, the director of the sub-bureau was alarmed.

"Director, what now?" asked a technician anxiously.

"Although the system backdoor and hardware backdoor were discovered, since he connected the network fiber optic cable, we still have a way. If you find that there is a particularly large amount of traffic, you should report it immediately. The director of the sub-bureau said in a deep voice.

On the third floor of the basement, Du Yu smiled slightly!

Erasing the backdoor of the system and the backdoor of the hardware is because Du Yu does not want to be exposed to some special departments at any time and does not want to be monitored.

Du Yu changed the operating system of the Tianhe-9 supercomputer, installed the Huanyu operating system, and completely modified the system source code, so that it would be impossible for the technicians who built the Tianhe-9 supercomputer to snatch control of the supercomputer from Du Yu's hands.

"Cangnan, three Tianhe-9 supercomputers, as the servers of Huanyu Group, important numbers, are backed up in the quantum supercomputer. Quantum supercomputers, as backup servers, also store numbers. ”

Du Yu communicated with Cang Nan in his heart.

"Master, are you going to upload the Huanyu mobile phone smart operating system now?" Cang Nan asked Du Yu for instructions.

"Upload now!" Du Yu said in a deep voice.

As a result, on the official website of Huanyu Group, in the free download area, the Huanyu mobile phone smart operating system appeared.

Then, Du Yutong Guò Group sent an email to all employees of the entire Huanyu Group, just to promote the Huanyu mobile phone intelligent operating system!

In the email, Du Yu hoped that all employees of Huanyu Group would download the mobile phone smart operating system for trial, because in essence, the Huanyu mobile phone smart operating system only covers the original mobile phone operating system.

Whether it's Android, Apple or WP, it can be overwritten.

Of course, the Huanyu Smart OS can also be set up to restore with one click, and if the user doesn't like it, they can uninstall the Huanyu Smart OS.

Du Yu will never do anything coercive, he believes that with the excellent performance of the intelligent operating system of Huanyu mobile phone.

Once the user is familiar with it, it is reluctant to uninstall again.

Back in his office, Du Yu received a call from his friend Wang Lei!

"Du Yu, you kid, you can buy the Qi Group quietly, if it weren't for the fact that I read the official website of the Huanyu Group on a whim today, I wouldn't know that the Qi Group has changed hands. ”

Wang Lei's surprised voice came from the phone!

"Qi's Group is not a large-scale group, which is equivalent to the Wang Group, which is not worth mentioning. Although Wang's Group is not listed, its market value is estimated to be at least more than 500 billion yuan. Du Yu said with a chuckle.

"The Wang Group is not mine, and besides, a collateral like me is not qualified to be in charge of the Wang Group. From now on, you will cover me. Wang Lei smiled.

"One man, two brothers. Our brother, what are you polite about. Du Yu did not forget Jì, Wang Lei's helping hand at a critical moment.
