after triggering a certain condition

Although this hot potato was given to Xiao Yan, everyone still tried their best to help wash the trash can, but when it was time to wash, it was even more fortunate that they didn't go in.Because it was so stinky, a deep and strong sour smell, even if they just stayed aside, they would be suffocated.

In the end, there was no other way, everyone was determined, and several people took the mop and swiped it twice to remove the old dirt, and then continued to flush. After flushing for a long time, they finally felt that they could come back to life.

But although the smell has faded, it's only for the people outside. For the people inside, they still have to scrub the dirt on the inner surface of the trash can by themselves.

Anyway, they still cleaned the trash can.

Cut off the bottom of one of the trash cans, then glue the mouths of the two trash cans together, cut off the two handles on the mouth of the bucket, and glue them back inside.After confirming that it was firm, two more holes were dug, and Xiao Yan slipped it in.

He tried to see and walk, and found that it was very suitable. The positions of the two holes were just right for him to see the outside, and the two handles were also suitable for him to hold and walk the shell.

It was already night now, and with the help of the lights in the corridor, everyone looked around carefully twice, and after Xiao Yan walked back and forth, they were sure that it would not be exposed, so they were relieved.

Zhou Dadong, who was standing next to him, sighed more than once. Fortunately, the trash cans in his school are higher and stronger than those in other schools. These students always say that they are heavy and tired when carrying them. Now you know. ?

Here Zhou Dadong was satisfied and proud, and Xiao Yan inside looked at Bailang unscrupulously. These holes and handles were all made of Bailang. The only person who could know him so well was Bailang.

Xiao Yan's gaze became deeper and deeper, and beneath the depth was an unending gentleness. Just when these emotions were about to be conveyed to Bai Lang, Xiao Yan's sight was blocked.

That irritating study committee member leaned in front of Bailang again to try to persuade him, so that he couldn't see Bailang anymore.

Xiao Yan lifted the shell up vigorously, and then Jiang Fuzi and several other classmates hurried to help, for fear that Xiao Yan would break the shell when he got excited, and they didn't want to wash it again.

Yes, Jiang Fuzi is one of the sad trash bins, because he is the squad leader, but now, he regrets it, what can't be done with the trash bins they wash so clean?

He would rather set the trash can than wash the trash can! ! !

For humans, they usually do not do dangerous things at night, because human beings are subconsciously afraid of the dark night, which is instinctive.No one suggested that we should go to experiment tonight. After checking the results of labor, everyone went back to rest tacitly.

Everyone agreed that tomorrow is the daytime to go to the experiment, including Bai Lang and Xiao Yan.

Of course, there is another reason, that is, the opponent can persist for about three days, and their time is not too tight, so there is no need to take risks.

The next day, Xiao Yan and Bai Lang set off for the school gate because they thought it would be a waste of time if there were too many people.But at about the same distance, Bailang stopped, not daring to move forward.

The two stopped, and Bai Lang helped Xiao Yan get into the trash can shell, and after looking around for nothing, he patted the wall of the trash, "Let's go."

Bailang sincerely hopes that he can succeed this time, and Xiao Yan also hopes so.

Bai Lang stood at the school gate where he couldn't see clearly, looked up and looked out, that was where the other survivors were.For some reason, he always felt that that side made him flustered. From the very beginning, he seemed to be rejecting that side deep in his heart.

However, this feeling was absurd and incomprehensible. He didn't tell anyone, and even suppressed it to himself.

Xiao Yan approached a little bit, and the closer he walked, the slower he walked. He gradually felt that the air he breathed in his nose was full of bloody smell, thick.

Jiang Fuzi, who was standing on the edge of the classroom windowsill, couldn't help but want to cheer. He saw that Xiao Yan was only twenty steps away from the school gate, but the zombies outside didn't respond at all, which meant that they It worked!

Just when this joy was about to spread to Bai Lang and Xiao Yan, a disguised form appeared.

Almost in the blink of an eye, the zombies wandering around the school gate suddenly seemed to have a target, opened their mouths dripping with yellow water and rushed towards Xiao Yan, only to be intercepted by the gate.

It has been exposed, Xiao Yan didn't stay any longer, and quickly turned around with the trash can. Bai Lang, who had been paying attention to Xiao Yan, noticed that just after Xiao Yan was about ten steps away from the zombie, the zombie became dull obviously. Although they were still gathered by the door, they no longer slammed into the door desperately, and their heads kept turning, as if the target could not be seen clearly.

When Xiao Yan returned to Bailang, those zombies had gradually dispersed.

Bai Lang helped Xiao Yan take off the shell, and running with the shell consumes a lot of physical strength. Panting slightly, Xiao Yan looked at Bai Lang and asked, "How is it? Is there any information that can be further improved?"

Xiao Yan asked directly without thinking. He believed in Bailang. This time, his experiment was absolutely impossible to just try to see if it was useful. Although Bailang hadn't told him before, he knew that Bailang would definitely observe carefully and master it. More information.

Bai Lang and Xiao Yan walked back while holding each other, "Well. After a certain distance, they should still be able to see you, because the sight of the zombies in front will occasionally stay on you. But you can no longer cause them to attack. I guess it's because outside the effective range, you in their eyes are just a trash can, not their gnawing target."

Xiao Yan calmed down and continued to ask: "Then what do you think they use to judge my identity within the effective range?"

Bailang paused, and then said: "Could it be the smell?"

"smell?"

"Well. As human beings, we can't smell each other's human scent, but they are zombies. It doesn't rule out that they can identify us through our smell in the air."

Xiao Yan nodded, he accepted the explanation.

After returning to the classroom, as soon as Xiao Yan and Bai Lang made this guess, Chen Chen immediately answered the question, "It's easy, let Xiao Yan go there again. Only this time, let him use a dirty trash can. Class monitor, an unwashed trash can must cover up any smell, right?"

Chen Chen blinked at Jiang Fuzi, and the meaning of trickery was included in the effective suggestion. Jiang Fuzi only recalled the process of washing the trash can, and immediately nodded, "Yes, yes, Xiao Yan, you are wronged Let's go."

Xiao Yan looked at these one and two, and suddenly reflected in his heart, did he not communicate well with everyone at ordinary times, why did he think that he was so happy to do these things?

Just when Xiao Yan was about to speak up for himself, his most familiar voice sounded unexpectedly, "If it's just to cover up the smell, isn't there a lot of big jars of vinegar in the cafeteria? Just soak it in, isn't that all right? "
