The accuracy of this second shot will drop a lot, after all, Qin Yi has not adjusted after firing the first shot, and it is inevitable that he will miss at this moment, but the situation at this time is already more critical, and there is not so much time to aim.

Qin Yi's shot accurately hit the zombie's head, and Xu Ya's shot also followed, the zombie's head was directly smashed, it lost its head in an instant, and the strength in its hand gradually relaxed.

Li Lingxiao finally had a chance to breathe, he gasped for breath, and at the same time broke free with all his might, and then he used the concussive energy to smash the zombie's corpse, and then stopped.

"I mean, you're not going to whip a corpse like that, are you?" Xu Ya glanced at the unsightly zombie corpse and said.

"I don't, I'm just worried about it coming back and that." Li Lingxiao said, "I'm just in case." ”

"Really?" Xu Ya pursed her lips and didn't say anything.

"I don't think the top lab is necessarily at the top anymore." Qin Yi glanced at the zombie corpse and said suddenly.

"How?" Xu Ya asked.

"This zombie looks like some scientific researchers, and this building is a business building, so it is likely that it was a researcher in the top laboratory before its death, and it became a zombie after being infected, and the zombie basically does not have the ability to think independently, take the elevator or something, these zombies should not." Qin Yi said, "And after these people are infected, they should mutate into zombies in a short time, so it should be in a hurry to enter the elevator and go downstairs after being infected, and then turn into zombies in the process, simply extrapolation, it is now the twenty-fifth floor, and it becomes a zombie in the elevator on this floor, so it will descend from the fiftieth floor at most ......"

"So, this top lab is between the twenty-fifth and fiftieth floors?" Li Lingxiao's face suddenly realized.

"Theoretically, this is true, but my inference is likely to be affected by various unstable factors, such as the fact that this person has mutated into a zombie for longer than I thought, and of course, this top laboratory is likely to be between the twenty-five floors above." Qin Yi said, "I still think it's better to look for it separately, and this laboratory should occupy an entire floor, and this floor should also be closed to the public in normal times, so if this laboratory is really between the twenty-fifth and fiftyth floors, it won't be too difficult for us to find it......"

"Five-five-twenty-five, let's go search separately on five floors." Li Lingxiao said.

"Aren't we six?" Wang Yun was puzzled.

"This guy is trying to be lazy, right?" Xu Ya seemed to see something.

"What do you mean by being lazy? I've just had a fierce fight with the zombie, and I'm too badly injured to move, so it's up to you to find the lab. Li Lingxiao said.

"That Brother Li, in fact, it is also possible above the fiftieth floor, you might as well go up and take a look......" Qin Yi said indifferently as if he hadn't heard Li Lingxiao say his justification.

"Okay, since Brother Qin has spoken, then I'll go up for a while." Li Lingxiao finally had to get up helplessly and enter the elevator.

There are a total of six people, each looking for five layers, this workload is actually not too large, and Qin Yi's analysis limits the search location to thirty layers, which can also be said to reduce a lot of workload, of course, if it can really be found in these layers, it will be even better.

Except for Song Ke, who searched for the twenty-fifth to thirtieth floors, he did not take the elevator, and the rest of the people took a multiple of five floors before getting off the elevator, and Li Lingxiao was the last.

Starting from the fiftieth floor, the other companions on the lower floors have not found anything, Li Lingxiao found some clues on the fifty-first floor, there is no staircase to enter on the fifty-first floor, it seems that he can only take the elevator, but after he entered the elevator, he found that there is no fifty-one floor in the elevator to choose from, he didn't think about it before, so he didn't find it, but now he found something strange.

"Guys, I've found something terrible, there's no fifty-one floor here!" Li shouted into the public channel of the microcommunicator, announcing his findings.

"No fifty-one layers? How is it possible, above the fifty floors, below the fifty-two floors, isn't it the fifty-first layer, you can't watch too much horror, right? Xu Ya said disdainfully.

Li Tianxiao quickly remembered some terrifying episodes, after the protagonist entered a certain floor, he suddenly found that the number marked with the floor was suddenly missing, or when he entered a certain floor, someone told him that there was no such floor at all, and he realized that there was something wrong with his expression.

"No, there is one on the fifty-first floor, but I can't go up." Li Lingxiao hurriedly explained.

"Okay, I see, it looks like the top lab should be there." Qin Yi said, "Then the others, if they don't find anything for the time being, they can go directly to the fiftieth floor, of course, if they don't finish searching, it's best to come back after searching the floor they are responsible for." Qin Yi said.

"You're lucky, you haven't looked for it yet, and you found this lab." Xu Ya said.

"Found it? Let's think about how to get to this fifty-first layer first. Li Lingxiao replied.

At this time, the rest of the people had basically searched for the same, and did not find anything unusual in the five floors they were responsible for, so they all went to the fiftieth floor one after another.

Soon, the other five people had reached the fiftieth floor one after another, and Li Lingxiao was also waiting here.

"I really can't go up to the fifty-first floor." Xu Ya said after looking at the situation in front of her.

"yes, so even if we think this fifty-first floor should be the location of the top lab, how do we get in?" Li Lingxiao said.

"There must be a way, the person in charge of the top laboratory should have negotiated with the person in charge of this building, and the fifty-first floor will not be opened, but those scientific researchers must have a way to enter, there must be other passages...... Qin Yi said in a deep voice.

"Could it be that there is an invisible staircase hidden in this overhanging place?" Li Lingxiao said and touched the place where the stairs should have existed, and soon a cold touch came from his hands, "I said, it won't be so accurate, is there really an invisible staircase here?" ”

"I'll try." Qin rushed over when he heard the sound, and sure enough, he quickly discovered the hidden staircase, and then said: "It should be some means to hide this staircase, and ordinary people know that the fifty-first floor cannot be entered, and if they see the empty staircase, they will also have the intention of retreating, so this fifty-one layer has been hidden very well......"
