Cheng Jiali woke up feeling like a century had passed, she didn't know that she had been in a coma for a long time, she only knew that she was very unwell.

It was like dragging heavy stones, and her lead-filled legs were unable to lift, she felt very tired, and her heart was still inexplicably painful.

She frowned slightly, clutched her chest, and closed her eyes to calm herself.

Rubbing her slightly sore temples, she had the energy to think back to what had happened before. It was obviously something that happened not long ago, but her memory was blurry, and that memory seemed to be blocked, but she wanted to remember it desperately, but it became heavier and heavier.

"The program is loading, please be patient." The cool tone sounded, Cheng Jiali was shocked, and hurriedly raised her head.

The stone shining with blue light in front of her was shaking, Cheng Jiali was pleasantly surprised, and her bright eyes were overflowing.

"Xiaobu?"

"The program is loaded, and the Buenci UN20 is at the service of the owner." The flickering blue light was even more dazzling, Cheng Jiali was immediately happy, and forgot about her personal grievances, pointing to the front and saying happily and briskly: "I don't want to run......"

Cheng Jiali pursed her lips, and her thick black eyebrows wrinkled into a figure of eight.

"Please confirm if the time reversal mode is turned on." A deep voice came from her ears, and Cheng Jiali's eyes widened instantly.

What the hell is time reversal?

Looking at the place where the light was shining directly, Cheng Jiali's face turned pale in an instant, and her hair scattered in the air was like her messy heart at the moment.

The scene below was chaotic, dozens of people were gathered together, and Cheng Jiali had a full view of the looks on their faces.

Frightened, flustered, nervous, dazed......

"Disperse, everyone, she needs fresh air." It was the head teacher's voice, and the thick male voice trembled.

The frightened classmates retreated a few meters on their own, and looked at Chen Liming, who was eagerly running here.

In the face of emergencies, their hearts are chaotic, and they have no ideas in their hearts. Chen Liming, the only calm one, has undoubtedly become their backbone and everyone's hope.

Ran in front of Cheng Jiali. Chen Liming squatted down and reached out to pinch her midriff.

Cheng Jiali's body trembled, and she couldn't take her eyes back for a long time.

How could she be lying on the ground? So how did she see this qiē now? What the hell is going on?

The big screen above flashed, Cheng Jiali stared at the picture of switching by herself without squinting, and she clearly saw from the picture that she fainted during the running.

"According to the objective analysis, the owner's health has dropped to zero." The deep tone seemed to remind her of this.

Cheng Jiali shook her head, and her trembling body almost stumbled. It was easy to steady, and then I found myself floating in the air.

No wonder there was a fluttering sense of trance before.

"The owner's health has dropped to zero, please confirm if the time reversal mode is turned on?" Cheng Jiali is a little blind, and she can't accept the reality that she is dead for a while.

Nima, why is she hanging again...... Cheng Jiali looked back at the sky, "God, I have a grudge against you." She yelled hysterically.

"The owner is not in good condition at the moment, and the owner of the UN20 has chosen the time reversal mode." Can you try to hang up your love xù good? Cheng Jiali smashed a roll of her eyes, and the text converted on the big screen stunned her again.

Time Reversal Mode: Takes the owner back in time to a point in time, but still retains all of the owner's memories, and according to the risk assessment, the owner can choose to avoid a series of troubles.

Cheng Jiali understands, and of course chooses the reversal mode in this situation.

Her mood changed in an instant, and she raised her hand to press the yes button on the left, when a deep and magnetic voice came: "The owner confirms that the time reversal mode is on." ”

Once the time reversal mode is selected, it cannot be changed, please confirm whether it is enabled again.

Cheng Jiali nodded indiscriminately, only to see a dazzling white light flashing, all the scenes are changing, each point in time corresponds to a number, the flying number dazzles her, she feels that the world is spinning, and in an instant, it seems to have fallen into a whirlpool.

After making sure that the surroundings were settled, Cheng Jiali opened her eyes hesitantly.

In fact, before that, she made up a lot of brains. Thinking about where and at what point in time the opportunity will take her back. That's right, she called it a time machine, so witty that she couldn't help but steal fun.

The middle-aged man across from her had a dull gaze, and his formal professional suit matched the black hair well, but despite this, he seemed to have no energy, and the whole person seemed to have lost his soul.

"Teacher Chen?" Cheng Jiali screamed tentatively, but the person opposite remained motionless as if he had fallen into an evil spirit.

Cheng Jiali took another big step forward and got closer to Chen Liming. She cleared her throat and shouted again, louder than before.

Her voice was so loud that she felt like the whole school building could hear her, but strangely no one answered her, and the classrooms seemed to be petrified like a few stone statues.

Could it be that time has stood still? Cheng Jiali raised her eyes and looked at the gray sky. Today's weather doesn't look very good, there is no sun, and the sky seems to be covered in smoke and fog.

"The time reversal accelerated to 7:21:05 in the morning, and the starting incident was that the owner was walking to the classroom of the second and third classes of high school, and was about to face the punishment of the head teacher Chen Liming, because he went home early last night."

The analysis of the machine qì person is very reasonable, and Cheng Jiali did listen to it, in fact, even if it doesn't explain it, she knows what is next.

She remembered that she had said that her memory would always remain.

But that's not the point, she only cares about the result, and the only thing she can do now is to get the team to break off the idea.

But she's not a god, and the team will listen to her?

"Please confirm that the memory erasure function is selected." Clueless, she suddenly opened her mouth when she heard the voice, and her eyes sparkled as she looked at the person opposite.

"I'm sure." The voice is sonorous and powerful, and if you look closely, you can still hear the brightness and cheerfulness mixed with it.

Memory formatting or partial deletion.

Cheng Jiali's confused gaze swayed on the left and right buttons, the literal meaning is very simple, she can still understand it, she passed the memory formatting on the spot, and formatting doesn't mean that the memory is all gone, oh my God, it feels terrifying when you think about it.

Then select Partial Delete.

"The owner has selected a partial deletion, please confirm the selected area again." Then Cheng Jiali saw something similar to a room, of course, not a room, but a model, but she explored it and found that it was not a house, just a space.

However, this space is curious......

Cheng Jiali's eyes rolled, and then her eyes fell on the top of her head, and her eyes lit up instantly.

She remembered, isn't this the brain model of a person in biology class?
