At this moment, the companions of the terrorists who rushed to hear the news surrounded the infirmary at the moment when they closed the door safely.

Looking at the door of the infirmary that was suddenly closed, the terrorists asked with some uncertainty: "Lao Wang, Lao Zhao, are you inside?" ”

After waiting for a long time, there was still dead silence in the infirmary.

Because of this unusual situation, the terrorists began to feel a little uneasy, and tried to break open the door of the infirmary.

At that moment, a gray and smoking object was suddenly thrown out of a window with a small slit open.

After a pungent smell of gunpowder, looking at what was thrown at their feet, the terrorists couldn't help but curse: "Damn, where did the grenade come from!" ”

Because the grenade appeared so suddenly, the terrorists didn't have time to flee for their lives, and they were all blown to the ground by the grenade.

An Ran was relieved to see the effect of the grenades he had found from the two dead terrorists.

However, the movement here is a bit too big, and it may not be long before more enemies will surround them.

So, An Ran hurriedly asked Teacher Yao in the infirmary: "Teacher Yao, in this infirmary, in addition to the door in and out, are there any other hidden secret doors?" ”

After listening to An Ran's words, Teacher Yao thought for a while, and then his eyes lit up and said: "If I remember correctly, under the bed in this infirmary, an underground passage was once dug, but this passage has been useless for a long time, and I am not sure if it has been abandoned." ”

"Then let's go down and take a look, whether it's still useful or not, it's much better to have a channel than no channel." An Ran thought about it and smiled.

An Ran was about to pull out the hospital bed, but found that Twilight, who had disappeared from the previous mission in the infirmary, suddenly appeared out of thin air.

Seeing the sudden appearance of the person, the other three people in the infirmary, except for An Ran, were all stunned, and An Ran looked at Twilight Xue and asked angrily, "Where did you go before?" ”

"I've found a way to freely enter and exit your mission plane, and I've gone to do a little bit of personal business before." Twilight whispered in An Ran's ear.

"Enron, who is this man? Where did it come from? The squad leader on the side asked with some curiosity.

"Well, this, he's my cousin, a member of the national special forces, as for why he suddenly appeared here, I'm sorry, this is a state secret, no comment!" Because he really didn't know how to explain, Enron weaved a reason indiscriminately.

Looking at his statement, the three people in the infirmary did not feel unreasonable, and An Ran was about to breathe a sigh of relief, when a voice in his mind that An Ran never expected suddenly came: "Warning warning, there is an unreasonable phenomenon in the mission plane, this mission plane is about to collapse, open the emergency repair procedure of the mission plane, the B-level mission plane will be automatically upgraded to A-level, and the doomsday element will be loaded in the middle ......"

Hearing this prompt, An Ran was speechless for a while, and directly said angrily in his mind: "Speak human words!" ”

"Master, that is to say, this task plane and another doomsday plane are superimposed, and in 5 minutes, zombies will appear in this world, and the master will complete other tasks that will be triggered in addition to the previous tasks." Yoyo hurriedly explained.

"Does that mean that if I want to use the things in the system backpack and the immortal cultivation skills, I can be unrestricted?" An Ran said with some eagerness.

"Master, what you say is theoretically correct." Yoyo replied, "By the way, upgrading the mission level also means that the reward after the task is completed will also be greatly increased, master, why don't you use the Koi Fu Card quickly and multiply the task reward tenfold again?" ”

"That's right! Use Koi Fuka for me right away! An Ran became more and more excited, and even the look in his eyes that looked at Twilight became complicated.

To be honest, if it weren't for this guy's sudden appearance, Miss Ben's mission wouldn't have increased the reward, and the abilities given to me by the system wouldn't have been used unscrupulously, but the mission escalated meant that the crisis had escalated, and I suddenly didn't know what to do with the culprit in front of me.

Of course, mission upgrades or anything will not have any impact on the NPCs of the mission plane at all.

Therefore, the squad leader only took a deep look at Twilight Snow and turned to An Ran and said, "Then let your cousin help open the underground passage with us." ”

"There's no hurry." An Ran smiled calmly.

At this moment, a large group of people screamed suddenly came from the campus surrounded by terrorists.

Everyone in the infirmary looked for prestige, and they saw that in the surrounded school, a dozen terrorists covered in blood and terrified suddenly ran out of the classroom.

The terrorists, who were supposed to go to the infirmary to check on them, also turned back to the school because of this movement.

I saw those injured people desperately banging on the campus gate that was locked by chains, and dozens of meters behind them, there were several people with black faces, blank eyes, incomplete bodies, and dark blood constantly flowing from the wounds.

These weird guys, judging by the extent of their injuries, can't be alive at all!

As a result, several terrorists outside the campus who were the first to arrive at the school gate looked at their frightened companions on the campus and asked with a puzzled expression: "What's going on inside?" ”

"Help, help! Hurry up and open the door, a man-eating monster suddenly appears in the school! On campus, the injured people spoke nervously.

Of course, the reason why An Ran was able to hear their conversation was due to her unusual hearing, and the other three people in the infirmary, except for Twilight, asked with a puzzled face, "Is there an accident in the school?" ”

Looking at the three confused guys, An Ran felt a little tired, and insisted on not continuing to carry these oil bottles with An Ran, so he pretended to be enthusiastic and said: "I'll go in with my cousin later, you guys find a way to leave the school first." ”

Although he felt that it was a bit immoral to let An Ran face such an unknown danger alone, but thinking that he really couldn't help anyone, the three of them nodded silently.

They then moved the infirmary bed to another location and climbed down through the one-person hole under the bed.

An Ran took out 3 flashlights from his backpack, handed them to Mr. Yao, and then restored the bed to its original position again.
