Just a few seconds after turning his back, Lu Fei's shoulder was patted by Yao Rong.

He didn't care.

"If you don't drink water, forget it."

It's okay not to mention water, but when it comes to water, Lu Fei is thirsty.

He stared at the wall for two seconds and sat up silently: Forget it, before arguing, let's drink some water strategically to quench our thirst.

The water was filled with calming and pain-relieving medicines, Lu Fei drank a few sips, the pain eased a lot, and his frowning brows finally relaxed.

Yao Rong still maintained a sitting posture with his back to the camera: "Next, you listen to me and say a few words, don't respond, and don't react in any way." ”

Lu Fei lay down calmly, closed his eyes and pretended to sleep, but in fact quietly pricked up his ears.

"In the past two days, I will prepare some more potions for you to restore your physical strength, and then you can drink it obediently, and you can recover as much combat power as you can."

"In two nights, I'll take you out of the institute."

"It doesn't matter how I do it, and I don't have to worry about my omissions, I must have taken into account everything you can take into account."

Lu Fei: "......"

Damn, no matter how the world changes, there is only one thing that will not change: Dr. Yao's mockery of him.

"Your previous outburst injured all the security personnel of the research institute, and also completely destroyed the most heavily defended bottom layer, which greatly reduced the difficulty of my operation."

Lu Fei's eyes rolled, this is about the same.

Yao Rong smiled silently, looked up at the clock hanging on the wall, got up and rang the bell, and called the other researchers to come and guard Lu Fei.

There are still a lot of things to be busy in the past two days, and she has to go back and get a good night's sleep to adjust to the best condition.

But as soon as he walked out of the room, Yao Rong was stopped by Dr. Chen.

Today's Dr. Chen is full of spring breeze, sweeping away the depression of the previous two days: "Dr. Yao, I heard that gene stabilizers have been developed?" ”

"The research has been studied, but there should not be many test subjects who can withstand gene stabilizers." Yao Rongqiang fought mentally and said objectively.

"Are the side effects huge?"

"It's going to hurt a lot." Without waiting for Dr. Chen to be disappointed, Yao Rong added with a smile, "But this is the 10th version, and I will try to develop the 20th or 30th version, so that each test subject can survive the side effects of the gene stabilizer." ”

Taking advantage of this opportunity, Yao Rong made more requests.

Dr. Chen is now counting on the gene stabilizer to turn over, not only meeting all of Yao Rong's requirements, but also praising Yao Rong over and over again, and finally sending Yao Rong to the door of her room with courtesy.

This night, Yao Rong slept for a long time, and was finally woken up by the mechanical sound of the system.

[Ding, the chip controller has been successfully hacked]

[Ding, the data of the game bracelet has been successfully read]

His eyes were instantly clear, Yao Rong got up and went to the bathroom to freshen up, and by the way, let the system start to introduce the game bracelet.

[All the host's previous guesses about this world are correct, and the origin of this world is a programming language. 】

[This programming language is called kevi, which can run without any runtime environment support, and now I have parsed the source file of the game bracelet, does the host view it? ] 】

Yao Rong replied "check" and asked, "Kevi?" ”

[This is a programming language that belongs to this big world]

"I see." Yao Rong was clear.

Source code, in other words, is human-readable computer language instructions.

Similar to when a musician learns music, he learns through a stave.

The source code is the programmer's "staff".

A source file, on the other hand, is actually a file full of source code.

The system invaded the game bracelet in order to get this source file of the game bracelet.

A little, dense code appeared in Yao Rong's mind.

Yao Rong flipped for a while and didn't turn his head.

"It's so complicated." Yao Rong pressed his eyebrows.

Mastering a programming language is not an easy task.

Kevi is a programming language that can be used to build large worlds.

It will only be more complex than all the programming languages that Yao Rong has been exposed to before.

And the game bracelet is the most important prop in the last days, and its source file can't be simpler.

Yao Rong was not in a hurry to read this document, and first asked a very important question: "If I want to tamper with the existing programs in this world, how should I tamper with them?" ”

[A program written by the host itself, which is equivalent to a virus.] As long as there is a network interface, I can insert the program written by the editor-in-chief. 】

[But this big world is very complete, it has a self-protection mechanism, which is commonly known as antivirus software.] If there are too many virus programs, they will definitely be discovered. 】

[According to the calculation of the system, it is best not to implant more than three viruses in the same range within half a year]

"No more than three? That's enough, too. ”

The corners of Yao Rong's lips curled slightly, if this was the case, then she knew what to do.

It's hard to write a program that adds new functionality to an electronic product, but it's relatively easy to write a problematic program that affects the operation of an electronic product.

And in this way, she doesn't need to fully master Kevi, only the small piece of content she needs, and she can temporarily scrap all the high-tech weapons here.

Under Yao Rong's instructions, the system invaded the high-tech products in the research institute, obtained more source files, and made a summary of repeated sentences.

This kind of work is extremely tedious for humans, but it is easy for the system, and soon, Yao Rong sorted out the basic content of kevi.

Carefully jelling down everything, Yao Rong casually took out a notebook and wrote two pages of code on it.

"System, remember this procedure."

"When the time comes, I'll use it to save my life."

After making sure that the system had finished recording, Yao Rong tore off the two pages, burned them all with a lighter, and washed away all the embers.

Just wanted to put away the notebook, Yao Rong suddenly remembered something, and simply tore off the next few pages of these two pages and destroyed them, so as not to write too hard and the handwriting would be printed on it.

"What time is it?"

[It's 10:20 in the morning, and Xiao Bai will arrive at the institute tomorrow.] 】

In such a short period of time, the 20 version of the gene stabilizer will definitely not be studied, Yao Rong came to the laboratory and asked other researchers to mix some more 10 versions of the gene stabilizer, and herself, under everyone's noses, calmly prepared 10 levels of alkali and prepared a sufficient dose of explosive raw materials.

It was the blonde researcher who was going to stay in the laboratory tonight, Yao Rong directly approached him, saying that he was going to stay in the laboratory tonight to do research, she and the blonde researcher changed the order of duty, and she just stayed on duty today.

This is actually not in line with the rules and regulations of the laboratory, but whoever calls Yao Rong is the main person in charge of the laboratory, she can transfer the shift as she wants.

In this regard, Dr. Chan is not in her hands.

As the night darkened, the researchers left the lab one after another.

Until the early hours of the morning, Yao Rong was the only one left in the laboratory.

[Laboratory monitoring is blocked]

[Host, no one can show up in the lab for three minutes]

Hearing the system's words, Yao Rong quickly got up and pulled out a few hand-held garbage bags from the drawer.

She started with a garbage bag and filled all the genetic stabilizers, tranquilizers, and body enhancers in the lab.

Immediately afterwards, Yao Rong changed a garbage bag and filled a few bottles of water, a few bread and glucose in the cabinet.

After doing this, Yao Rong began to prepare the detonator at low temperatures.

The detonator needs to meet certain conditions before it can explode, and in order to make the detonator explode within the time period she wants, Yao Rong has already thought about how to use low temperature to make a time-delay device.

She moved very quickly and it took less than a minute to mix all the reagents.

After sealing it, Yao Rong held the flask twice, easily jumped onto the experimental table, used a wrench to pry open the shell of the ventilation duct, and stuffed the flask containing the detonator into the ventilation duct, and then restored it to its original appearance.

Even if someone else strayed into the lab when she left the lab, they wouldn't notice anything unusual in the ventilation ducts.

In the case of Ping'an City, which is full of zombies, the research institute is built underground, which will greatly increase security.

But there are also many disadvantages.

Underground ventilation and drainage require specialized equipment.

Ventilation, in particular, is a top priority.

When Yao Rong jumped back to the ground, only two minutes and forty seconds had passed since the three minutes the system said.

Yao Rong stuffed the other two flasks into the garbage bag and walked towards the elevator hall with the garbage bag.

"Dr. Yao, haven't you rested so late?"

An abrupt voice rang out from the side.

Yao Rong paused, and turned his head naturally: "Captain Zhou, why is it your turn to be on duty today?" ”

"Many of my subordinates' injuries are not yet healed, so I, the captain, have to do more."

The security captain was dressed in a black suit, and his eyes fell on the two garbage bags.

"Dr. Yao, how can it be your turn to take out the garbage yourself?"

Yao Rong lowered his head and followed the gaze of the security captain: "Who told me to be the last to leave the laboratory, these chemical wastes can be disposed of as soon as possible, and they can't stay in the laboratory overnight." ”

"I see." The security captain pointed to the trash can on the other side of the hallway, "But isn't the trash can over there?" Why don't you throw away the garbage and then go back? ”

Yao Rong had no choice but to correct: "Captain Zhou, the trash can over there is for domestic garbage, and chemical waste cannot be discarded casually, but must be put in a designated place for recycling." ”

"Oh yes, I forgot to pay attention to it." The security captain slapped his forehead, "I just said that if you don't bother to throw it over, I'll just help you lose it." Just as I was going over there to patrol. ”

The corners of Yao Rong's lips curled slightly, and he said softly: "Then I won't delay Captain Zhou's time." ”

"It's me who delayed your time, Dr. Yao will rest early after he goes back."

Yao Rong smiled bitterly: "I'm afraid I won't be able to rest for a while." I'm going to report to Dr. Chen first, and then I'll have to feed No. 9 some potions, and try to recover more of No. 9 before Dr. Xiao Bai arrives. ”

The security captain glanced at the time, it was more than three o'clock in the morning: "Then Dr. Yao should hurry up and get busy." ”

Seeing the security captain and his subordinates leave, Yao Rong opened the elevator with the permission card and went directly back to the second basement floor.

The elevator she took went straight to the dormitory area, and there was no one else in the corridor at this point, so Yao Rong was in no danger and returned to his room smoothly.

She took a flask out of the garbage bag and put it in the ventilation duct in her room before taking her duffel bag out of the closet.

The contents of the duffel bag had already been sorted out, including her two sets of clothes, two sets of lab coats suitable for Lu Fei, and food for two days.

After filling these things, there is still half of the space left in the duffel bag.

Yao Rong emptied all the contents of the garbage bag into his bag.

By the end, all she had left was a flask and a body booster.

"System, help me block the hallway surveillance."

After saying this, Yao Rong picked up the heavy duffel bag, carried the tray containing the flask and body enhancer, and left the room.

As he was about to walk out of the dormitory, Yao Rong stopped, took off his duffel bag, and stuffed it into several foam boxes piled up there.

Her series of movements were smooth and fast, and it took less than ten seconds to do so, and it was obvious that she had already rehearsed.

After hiding the duffel bag, Yao Rongcai held the tray and walked to the room where Lu Fei was being held.

Lu Fei was lying on the bed, feeling weak.

Since that day, Yao Rong has not appeared again.

He didn't know what she was doing, and he didn't know what was going on outside, so he could only drink one reagent after another patiently.

Seeing that the time agreed between the two had arrived, Yao Rong still did not appear, Lu Fei's mood was very worried, for a while he was worried that Yao Rong's plan was wrong, and for a while he was worried that Yao Rong was caught red-handed and then became an experimental subject like him.

But the surveillance camera in the room was always aimed at him, and Lu Fei didn't dare to act rashly.

Just when his mood sank deeper and deeper into the bottom-

The door to the room opened from the outside.

A security guard's voice came in: "Dr. Yao, I have just confirmed with Captain Zhou, you can go in." ”

Lu Fei's mood was like a roller coaster, and he fell back to his place in an instant, he quietly opened half of his eyes, watched Yao Rong walk in intact, closed the door of the laboratory casually, stuffed the body enhancer to him, pulled over a chair, stepped on it and began to dismantle the ventilation duct shell.

Lu Fei was dumbfounded: Isn't this too blatant.

However, Lu Fei didn't dare to ask.

Judging from his years of experience, as long as he asked, he would definitely gain Yao Zhi's contempt.

He'd better obediently dispose of the potion in his hand first.

When Lu Fei drank the medicine, Yao Rong also successfully put the flask.

"How's your body recovering?"

Lu Fei squeezed his fists: "You can run, you can jump, you can fight." ”

"That's good."

Lu Fei shook his wrist: "How to take off this bracelet on my wrist?" ”

This bracelet worn on Lu Fei's wrist can not only detect Lu Fei's body data in real time, but also restrict Lu Fei.

The length of the connection between the bracelet and the machine is one meter, and he can only move within this meter, as long as he exceeds this range, the bracelet will immediately release an electric current that can instantly stun him.

And in addition to the bracelet, this room and corridor are arranged with various weapons. Yao Rong has permission cards and will not be attacked, but these weapons will not show mercy to the deer.

Yao Rong: "This is easy to do. ”

Lu Fei looked at her with a blank eye.

Yao Rong said to the system in his heart: "System, implant the program I wrote into this bracelet." ”

The autonomous weapons of high destruction of this research institute all have trigger conditions when they are automatically triggered.

For example, this bracelet will be triggered when the deer is not within a one-meter range.

And the program written by Yao Rong is actually a virus that can affect the automatic triggering of weapons.

- When there is a conflict between the program that comes with the weapon and the program she wrote, the weapon will report an error and cannot be triggered automatically.

Lu Feiyan waited for a while, and after seeing that Yao Rong finished saying "This is easy to do", he stayed where he was and did not move, subconsciously wanting to urge her. But as soon as he opened his mouth, he clearly felt the bracelet's restraint on him loosen.

He was stunned and immediately reached out to untie the bracelet.

The bracelet that couldn't be untied no matter what happened before was broken this time under his violent pull.

Could it be that Dr. Yao just used an ability? Lu Fei could only think of this explanation.

"If I fool those two security guards in, can you stun them in the first place? They are all supernatural beings. ”

Lu Fei assessed it and nodded.

"Then you stand behind the door."

Outside the room, two security guards stood upright with guns in their hands.

Suddenly, the door opened, and Yao Rong looked panicked: "Nine's current situation is not right, you need to take a tranquilizer immediately, you help me hold him, he struggled too much." ”

Thinking of the terrible scene of No. 9's madness that day, the two security guards did not dare to delay and followed Yao Rong into the house.

As soon as they entered the house, the attention of both of them was attracted by Lu Fei, and they didn't even pay attention to Yao Rong closing the door casually.

They hurriedly stepped forward, intending to hold Lu Fei left and right, but at the moment when the two sides made physical contact, Lu Fei, who was constantly twitching, jumped up suddenly, kicked the left ability to the wall with all his strength, and smashed the opponent's head with a punch before the person on the right could react.

The two fainted on the spot.

Before Lu Fei had time to get nervous, Yao Rong reached out and grabbed Lu Fei's arm: "The person on duty at night needs to have a conversation through the walkie-talkie every twenty minutes, let's go!" ”

Before rushing out of the room, the system had implanted the virus into the central system. All the weapons in the corridor are under the direct control of the central system, and abolishing the central system is equivalent to abolishing these weapons. So there are no weapons that automatically attack Lu Fei along the way.

The two of them rushed back to the dormitory and got the duffel bag hidden in a foam box.

"On my back."

Yao Rong said to Lu Fei.

Lu Fei hurriedly put on his bag and followed Yao Rong to the elevator room.

But just as he was carrying his bag, a rapid first-level alarm suddenly echoed wildly throughout the research institute.
