Zhang Yanfang glanced at Deputy Director Zhou, and did not take the initiative to speak again, but secretly surrounded the two with him.

The young man seemed to be still unknown. He stepped forward and said enthusiastically: "Sister Zhang, we didn't see you just now. We thought you were lost, so we ran to the escape exit and came back quickly. Fortunately we found you now."

"Oh?"

Even an elite spy like Zhang Yanfang is confused. Does this person have a ghost, or does he really want to come back and save him?

However, with the presence of Deputy Director Zhou, they can't get over the big wave.

Zhang Yanfang looked at Deputy Director Zhou and said, "Director Zhou, I remembered one thing. I am afraid that the probe technology will not be able to withstand refrigeration, so I came back and planned to take it out of the institute first and put it back after the incident. ."

"you're right."

Deputy Director Zhou nodded quickly and stepped forward and said, "Now the system is closed, and only the level A and above can be opened. I happen to have this right."

Zhang Yanfang walked back two steps calmly, and while giving way to the position, he also monitored the young man and Wu Hua to prevent them from suddenly violent and wounding.

Deputy Director Zhou took out his work card and swiped it towards the door. An electronic sound came from the closed door: "A-level authorization card was recognized, and the main control system has entered the dormant state, so the security level of entering the laboratory is improved. Level one, please reconfirm your authorization."

"what's the situation?"

Now everyone is confused. Doesn't the system broadcast mean that A-level permissions can open important databases?

Zhang Yanfang frowned. Sure enough, the things in this base are not so easy to get, especially the most important probe technology.

He tried to swipe up his house number, which indicated the C-level permission.

Wu Hua is even more pitiful. The authority level is only D level, which is the most basic authority level.

"It should be due to the authorization of the director," Wu Hua said hurriedly, shaking his whole body, "Let's go, it seems we can't open the door."

Zhang Yanfang looked at Deputy Director Zhou, and the two exchanged eyes for a while. Deputy Director Zhou gritted his teeth and stretched out another house card.

"If the S-level authorization card is recognized, please stand in front of the door and face the camera. The recognition system will recognize your face."

The blunt electronic sound shocked everyone's spirits. Wu Hua looked at Deputy Director Zhou with a weird expression. He actually has a good house card? !

Zhang Yanfang and Deputy Director Zhou both smiled bitterly. They didn't think that they needed face recognition in addition to the authorization card. Where are they looking for the director's face to fool the system?

As for forcibly opening this door is even more impossible. In order to prevent the virus from leaking, ordinary doors are at least half a meter thick, and the important database is so thick that the innate doubts about life, and it is impossible to open it by brute force.

"The protection of this door is really in place."

Deputy Director Zhou said with a sigh, and stepped forward, looking at the camera at the door, expecting a miracle to happen.

For example, if the face recognition system fails, skip the recognition step and open the door directly.

"Di~, I have identified Zhou Tianyu, the owner of A-level authority, and those with A-level authority carry an S-level house number, and the authority level is higher than A-level, the authentication is successful, and the door will open soon.

Everyone was shocked, is this okay?

Deputy Director Zhou and Zhang Yanfang were even more excited, and Liu Anhua was in another village. They didn't expect that the system would not recognize whether the house number matches the person.

But on second thought, this was probably to prevent the director from accidentally dying and unable to open the door. After all, the ice-covered state of the research institute had a disaster on the surface, and it was normal for the director to die.

The first iron door opened quickly, followed by the second tempered glass door, which was used to isolate the air, then the heavy stone door, and finally another iron door.

All the doors opened together, revealing figures full of people inside.

"do not move!"
