"Everyone, wait a minute." Dunn couldn't help but stop the crowd after another hour of walking out of the group.

Lily and the others looked back at Dunn, who was walking at the back of the line, with a little confusion on her face.

"Don't you look at these cars on the side of the road, these billboards, these street lights, the walls of these buildings, don't you think there's anything strange?" Dunn asked.

Lily immediately looked around, the silent fog was still rolling and rolling 24 meters away, and the ground, street lamps, walls, and billboards that could be seen around were corroded, peeled, painted, and rusted because no one had maintained or repaired them for a long time.

"What did you find, Dunn?" Lily really didn't see any big problem, so she asked Dunn rhetorically.

"Oh God, I mean, it's only been three months since we first went out to explore the 'wall', and just three months have allowed us to make things around us so old?" Dunn explained quickly.

"Perhaps...... Maybe it's the fog. Stephenson tried to suggest a possibility.

"Then why are the fences and facades of our orphanages all right? We all saw it when we went out, and the brand-new level of that fence was not at all the same level as what we could see now. ”

Dunn kind of hates iron and steel.

"Yes...... Issue. Aiden gave his opinion.

You must know that when the orphanage first set up an exploration team, although there were no pedestrians on the street, whether it was the shops on the street or the vehicles on the street, they were still in a state of just being abandoned.

Now that Lily was told by Dunn, she could see the problem when she looked at the shop billboards on both sides of the street, the wall coating, and the cars on the road that no one had driven in a long time.

It doesn't look like it can be formed in just four or five months!

While thinking about it, Lily suddenly remembered a shocking news that John brought back after his first contact with the exploration team outside the "wall" - the world outside the "wall" has passed for 10 years.

Although the things in front of me don't look like they've been corroded for ten years......

Lily immediately shared her thoughts with the others, but Dunn only shook his head, and he couldn't tell why.

"We ...... Should...... Begin...... Do...... tags. Aiden broke the silence and took chalk and oil pens from the side pocket of his backpack and went to a corner or shop on the side of the road, leaving a mark.

He also watched for signs in the vicinity to see if anyone from outside the orphanage exploration team existed or had been here.

After walking out for more than ten minutes, Camille, who had been silent, suddenly pointed to a half-baked bakery on the corner of the intersection in front of him and said: "I like their milk very much, their milk is not only fatless, but also high in protein." ”

Stephenson turned his head to look at Camille with a blank expression, and thought to himself, sister, no, brother, what are you trying to express?

Aiden nodded deeply, and by the way, he also popularized a term: "skimming...... Milk. ”

He is also a big fan of this bakery.

Lily listened to the chatting of several companions around her, but she did not relax her vigilance, from John's disappearance to today, it is already the third day, if it is more serious, John had an accident not long after he set off, that is, five days, nearly a week.

Controllable variables? Probably only I have gained some abilities.

Suddenly, Lily felt a slight tingling in her right cheek, which made her subconsciously turn her head, and then she saw a black shadow quickly pass in front of her eyes, and after landing on the ground, it quickly jumped back and forth a few times, and then disappeared into the depths of the fog.

From Lily's sudden feeling of the tingling pain in her cheeks to the disappearance of the mysterious black shadow, it took less than 1 second in total, so that Sandra next to Lily didn't notice what was happening on Lily's side at all, only Aiden, who happened to be looking at this side from a distance, noticed something, and he immediately trotted back to Lily and asked what was going on.

Lily touched the right side of her cheek, very apprehensive. To be honest, if he hadn't subconsciously turned his head because of the sudden stinging pain, then the black shadow would have hit his face, and no one knew what would happen next.

"I don't know, it's just that something black seems to have flown over just now, and I didn't see what it was." Lily replied with a little trepidation.

"Black...... Target..... Things ......," Aiden repeated Lily's words, his expression becoming more solemn.

Lily also probably thought of something, and glanced at Dunn, who pondered for a moment and said:

"Whether it's our initial expedition or John's subsequent 'sieve tour', we've forgotten to think about one thing in the last few months."

Lily nodded, and duly added, "Animals." ”

"Animals?" Sandra repeated the word, slightly confused.

There aren't many huge animals in the city of Dunlun in the British Empire, oh no, except for the Dunlun City Zoo.

"What I want to convey is that although no one else in the city is gone except for our orphanage, both stray animals and smaller rodents are still roaming the city." Lily explained to Sandro.

"Fog...... Target...... Hazards, we ..... I don't know. Aiden, who had said this, glanced at Lily.

Lily immediately followed:

"But whether the fog has any effect on the animals is something we have to consider next."

"If these animals become more aggressive due to the influence of the fog, or even more mutate in size or even part, it will bring a lot of danger and hidden dangers to our next search for John."

"I've got some bad premonitions. Stephenson, Dunn, from now on, you go to the middle of the line, Aiden, you and Camille are on the left and right of the line, I'll go to the end of the line, and I'll leave you at the front, Sandro. Lily quickly formed a formation.

"Okay." The rest of the group responded in unison.

"Keep an eye on the surroundings at all times, I think this search operation is already above hell, in Ender's words, the abyss." Dunn put away his usual smile and took the lead in laughing at himself.
