Li Yun stepped forward and took a look at the blood on the ground. The shots just now should have hit Zhang Yanfang and the two, but a few shots in the hands of the congenital expert could not kill them. Even Li Yun seriously injured them just now. Able to escape.

When the blood splashed out, it should have scratched some transparent mucus, but after leaving the human body, the mucus quickly lost its effectiveness, causing the blood to slowly change from light red to red.

"Brother, they're in the hall!" Xiao Ai said suddenly: "I saw human footprints appear in the black residue on the ground, it should be them."

"Little Ai, good job!"

Li Yun lifted his spirits and turned his head and said to the people behind him: "Be careful. Collect these blood first and then come to contain them. I will chase them first."

The blood is mixed with the transparent liquid on Zhang Yanfang's body, which is also of research value.

"Wait, I'll go with you." Liu Yayu hurriedly caught up and let Li Yun face two invisible people alone. This was too dangerous. It would be much better for two people to rely on each other.

Li Yun did not refuse, and ran towards the hall with him.

"Brother, I heard the sound of their running. It should be running outside the escape route D. Do you want me to close the hidden gate of the escape route?"

The escape route does not have an automatically closed gate, only some gates that can be opened and closed inside and out to prevent some possible disasters in the institute, such as zombies, poisonous gas, or violent animals.

These gates can prevent irrational things from pursuing escaped people, but they cannot stop normal people.

Of course, this is just a device on the bright side. The research institute still hides several automatic doors at the escape port to deal with the current situation.

only…….

Li Yun asked as he ran, "Xiao Ai, these automatic doors on escape routes need permission to be closed, right?"

Of course, Xiao Ai does not need permissions. She has absolute control over all electronic devices in the institute. Or simply put, Xiao Ai is the executor of permissions. She gives permissions to whoever she wants, and controls which electronic device she wants to control. .

The premise is that Xiao Ai conducts these operations in violation of regulations.

The actual controller of the authority of the institute belongs to the entire Huaxia State, which authorizes the establishment of special operations teams and Qingya Institute, and Xiao Ai is authorized to operate under their leadership.

Compared to needing Xiao Ai's illegal use permissions, it is better for Li Yun to take a bit of effort to catch them.

Although this may cause heavy losses and may even cause human lives, Li Yun still does not want Xiao Ai to violate the rules too much.

If you violate the rules too frequently, you will lose awe of the rules.

"Well, S-level permission is required, and my brother has the right to close it," said Xiao Ai.

"what?"

"When the research institute was established and the intelligent control system was initialized, Uncle Murong set all four people in the special operations team with S-level permissions, including three people, brother, grandpa Qi, and grandpa Luo."

"That's it."

Li Yun didn't know about it yet, but he didn't struggle too much, and decisively ordered: "Xiao Ai, close the automatic exit door."

"Yes~~!"

Following Xiao Ai's order, several doors hidden under the ground rumblingly rose up, sealing the entire institute strictly.

Now Zhang Yanfang and Deputy Director Zhou, even if they are transformed into a mosquito, don't even want to fly out of the tightly closed research institute.
