It's been 10 minutes since nightfall. www.biquge.info According to the division of time, it is close to midnight at this time, and there are countless zombies wandering under the building, no different from the day, still so dazed, but there is no clear goal like last night.

This night seems to be the first night that everyone has spent peacefully since entering this world.

Rao is like this, Ling Ling and the others still did not relax their vigilance.

Just like last night, every two people are guarding the staircase in case of a fire in the backyard.

Under the high vigilance of everyone, time is also passing safely.

The dark corridor has no light. In the darkness, there was silence, and everyone seemed to be able to hear their hearts beating regularly.

The half-hour wait is as long as thousands of years; The torment in the darkness, the demons brought by the invisible pressure, from time to time provoked everyone's nerves, which were already tense to the point of no tightness.

Finally, a glimmer of brightness appeared in everyone's field of vision.

A glimmer of white light finally appeared on the horizon.

Dawn has finally arrived!

Seeing a glimmer of light, everyone's tense nerves were finally relieved.

Ling Ling exhaled deeply, waiting for everyone to return.

Geng Chao, who was closest to him, walked side by side with Ye Yuxi and became the first group of people to return to the team. With a relieved smile on his face, Ling Ling greeted him and discussed with him the most likely source of pollution.

First of all, they have determined the location of the building, which is where the source of the pollution exists. Now it's time to determine whether the source of the pollution is at a certain level above or at a certain level below.

If it's on it, then things get a lot easier. After all, at night, the floors above the 20th floor will be much less threatened by zombies, and everyone is likely to be able to complete this special task smoothly like yesterday.

However, if the source of the pollution is on the floor below, it is a lot of trouble. Not to mention whether they can find it, and even if they do, what should they do?

This is the center of the city, which means that there are countless zombie hordes around the building, and there is a high probability that there are multiple mutants. If everyone doesn't return to the 20th floor before nightfall, it means that they are likely to face a horde of zombies like a tide.

After some fierce discussion, a unified opinion was reached. Layer by layer, look for the source of pollution, and the estimated use time cannot exceed 7 hours!

Excluding today, the longest time anyone can stay in this world is 12 hours!

They had to search the remaining 26 floors and every corner of the roof in seven hours. According to the structure of this building, there are at least thirty or forty rooms on each floor, or a dozen or so miniature and small offices, and it takes hours to search a floor carefully!

However, at this time, the eight members of the 'Legend' team had to complete this task in seven hours, which required a dozen or even dozens of hours to complete.

The task is extremely arduous and the responsibility is extremely heavy!

"We had four teams, each searching six floors, and we needed to complete the task in six hours. Then we met on the forty-fifth floor, divided into two teams, and spent half an hour searching the forty-fifth and forty-sixth floors. Finally, we met at the rooftop, which took no more than 15 minutes. If we don't find the source of the contamination, we have to go back to this level within 15 minutes! ”

Ling Ling explained his plan to everyone and asked, "Are there any objections?" ”

"Nope!" They all replied together.

"Okay, do it now!" Ling Ling said in a deep voice.

After saying that, the crowd dispersed immediately according to the previous grouping.

Ling Ling took Ye Yuxin and quickly went up to the 24th floor, he asked on the radio, and learned that this floor had not been searched. He and Ye Yuxin immediately launched a carpet search on this floor.

Ling Ling quickly opened the doors of several rooms, and just stood in the doorway and glanced inside, and concluded that there was no target they were looking for.

"Why don't you go in and find out?" Ye Yuxin asked suspiciously.

"No!"

Ling Ling replied without replying, and quickly walked to the next room, still the same after opening the door.

He explained to Ye Yuxin very confidently: "Just by intuition, I know if there is something we are looking for in it!" ”

......

Outside the building, the sun and the moon alternate.

As night fell, the efficiency of everyone's search was reduced to the extreme. Everyone is the same, just open the door of a room, and there is nothing that can shine except for the darkness that can not be seen. In this dark night, you can't see anything, let alone what you can search for in it.

In this case, the searcher is also extremely devastated.

However, fortunately, none of the people in this team, except for the two sisters Ye Yuxin, are ordinary people.

They opened a random door and, by their instincts, were able to tell if there was a target they were looking for. As a result, their efficiency has increased a lot.

Six hours later, they had finally completed the seemingly impossible task.

"This is it!"

When Ling Ling had just opened the iron door on the roof of the building, a strange feeling surged into everyone's hearts.

They maintained their battle formation, their nerves tensed at this moment, and they cautiously poked out. The shadows of the eight people, stretched long, very long in the setting sun.

On the top of this vast and unobstructed roof, in the middle of the building, stands quietly an unidentified object like a beehive.

"This is it!" Ling Ling decided in his heart that this was what they were looking for.

They cautiously approached the object, and when they were a few meters away, night began to fall.

At this moment, a gust of wind blew without warning. The sky didn't know when it was shrouded in dark clouds, as if the actual haze was also like a dark cloud, enveloping everyone's hearts, a dull and dignified pressure, instantly turning the air heavy.

Just when everyone was puzzled, a bright lightning bolt suddenly crossed the sky, falling straight on this unknown object.

Lightning is fleeting, but the real threat is quietly approaching!
