When I returned to the girl's side, I looked at it for a long time and found nothing except the constant ringing of bells in my ears.

The window was finally smashed by the indomitable zombie army, and the debris splashed Xu Mengyao's body, and many of them casually cut the girl's already broken body.

The crisp sound of "Bang Dang" came from Xu Mengyao's feet, and when she looked down, she saw an ornament similar to a jade pendant tied to the girl's feet falling.

Xu Mengyao held the anklet in her hand suspiciously, and a detailed description of this thing floated in front of her in an instant, and the system also gave a reward very powerfully.

"Space Jade Pendant, Level 5, Bonus Experience: 2000 points."

Space Jade Pendant ...... This millionaire woman is really first-class in treasure hunting! Luckily, I got this set in my previous mission, otherwise I would have missed out on being so close to the treasure.

A few whips solved the zombies swishing at the window, and according to the instructions, they bit their fingertips and dripped blood on the jade pendant to recognize the owner.

"Bind upgradeable space, space level test ......"

"Soul Pact, untestable, program error, redebugging, restarting ......"

The sound of electricity kept ringing in Xu Mengyao's ears, her brain seemed to be about to explode, the current spread from her mind to the retina, a string of complex codes floated in front of her eyes, black and white blood flowers kept beating, I don't know how long it took for Xu Mengyao to wake up from this torture.

There was only a blackened red rope left in the palm of his hand, but the shadow of the jade pendant was still missing.

Where did the jade pendant go? Was the space you just got hacked by the system?

Xu Mengyao pointed the suspicion at the system as soon as possible, and the system reacted quickly.

"The upgrade space, which has signed a contract with the host soul, is no longer within the control of this system."

Is there anything that the system can't control? It's really unusual.

Xu Mengyao tried to enter the system silently in her heart, and her body was a flower, appearing in the space.

The whole space is about 100 square meters, and there is a puddle in the corner that is only the size of your face.

It's really just puddles, the kind of little puddles that go to the bottom with a finger poke.

"System, you give it to me, it's not a good upgrade space, it's a very advanced kind, why is it so big, even the water is just like that."

Xu Mengyao kept roaring in the space, she was the only one there, and she was not afraid of being heard, so she shouted extremely loudly.

"Space upgrade required: 200 first-level crystal nuclei and 10 second-level crystal nuclei."

Unlike the sound of the system sounded in this space, Xu Mengyao's brain was stunned for a moment, blinked her ignorant eyes, and shouted to the system in her heart more than a dozen times, but she didn't get any response, and her heart almost stopped beating in fright.

There was no way, Xu Mengyao had to exit the space and give it a try, and sure enough, when she called the system again, the system spoke.

"Space and system do not belong to one, please refuel the host to complete the task."

Originally, I was so happy to see the disappearing system, and I was not happy at all to be hit by refueling and completing the task.

System, what is the crystal nucleus?

"The crystal nucleus, the substance produced within the corpse, is not part of the mission."

Does the zombie I killed just now have a crystal nucleus in its body?

"Yes, is the host going to collect?"

Be.

"Turn on the automatic collection of crystal nuclei program, 100 experience points every 24 hours, and the daily auto-renewal has been deducted."

……

The experience I just gained disappeared by another 100 points because of the collection of crystal nuclei, and it still disappeared by 100 points every 24 hours.

No, I need to finish the task faster.

I thought I had got a baby, but now I find out that this is a baby!

This is obviously to get the rhythm of another system.

With an army green vest on the outside, army green cargo pants on the bottom, a pair of black boots under his feet, a black cap covering his eyes, and long hair tied into a ponytail, he jumped lightly from the obstacle and walked out of the room to look back and forth in the corridors around him.

This is a utility room on the first floor, and looking at the surrounding layout, it seems to be a school.

The school is sure that there will be more zombies, but now is the beginning of the end of the world, if you don't take advantage of the fact that everyone doesn't dare to go out and stock up on food now, I'm afraid it will be difficult to collect food when these days pass.

Thinking of this, Xu Mengyao decisively gave up the current action of cleaning up the school zombies, and her body was like a dexterous cheetah, running out of the corridor quickly.

As soon as he walked out of the hall, zombies roamed around the campus, and it seemed that he heard Xu Mengyao's footsteps, and all the zombies seemed to be crazy and rushed towards Xu Mengyao.

The long whip in his hand was a whip towards the most dense place of zombies, and the white light quickly flew into Xu Mengyao's eyebrows.

Is this what is auto-collected? It's really convenient.

Xu Mengyao looked at the neat speed of the system, and the price of 100 experience points a day was not so painful.

The survivors trapped upstairs saw Xu Mengyao's neat skills and the whip that emitted flames in their hands, and they all began to shout for Xu Mengyao's help.

"Are you the one who came to our rescue? Come and save me. ”

"They're too tall, I'm only on the second floor, save me first."

There were all voices calling for help all around, and Xu Mengyao glanced at the people who called for help to her, most of them were some strong boys.

If you're brave, it's not impossible to rush out with iron items.

"Hit the headshot and they'll die. I'm not here to save you, I'm a rakshasa and I'm busy! ”

After doing a simple job as a teacher, Xu Mengyao didn't say a word more, and sprinted towards the exit as fast as possible.

It may be that the cries for help from those people upstairs caused zombies to wander around the other places, and groups of zombies gathered towards the school, making the students who had just raised their courage scream in despair again.

Xu Mengyao frowned, although she was not very disgusted by the gathering of these zombies, but if these people continued to shout like this, it would only attract more groups of zombies to come.

"If you don't want to die, don't shout, the junior zombies can't see you yet, they just distinguish your location according to the smell and sound, and you will only make more and more zombies by shouting like this!"

Xu Mengyao's words still played a role, and most of the people stopped calling for help, but there were still some people who held the mentality that they couldn't live and didn't want Xu Mengyao to live, and they were still not afraid of death.

Frowning fiercely, he took out the silver needle from the space, and it was a flying needle far away from the person who was still calling for help.

Normal people can tolerate Xu Mengyao's stitches, and Xu Mengyao now knows the acupuncture points, and it is even more difficult to prick them on the acupuncture points.
