The group continued deeper into the area.

With Anlan's fog pollution detection equipment, the group tried their best to avoid conflict with the monsters and infected people in the fog.

If you encounter a large number of enemies that you cannot avoid, then fight them quickly and decisively.

As they delve deeper, the number of monstrous beasts and mutated beings increases, and their strength grows stronger.

Currently, the monsters and infected individuals that Lu Ning and his companions have encountered are all of the middle or even high level.

This also made everyone somewhat solemn.

Normally, high-level monsters and mutated creatures are rarely seen in small fogs.

Even if they exist, they will only appear in the core area.

However, before even reaching the core area, they have already encountered high-level calamity beasts and mutated beings.

This also reflects that there is indeed a great deal of anomaly in the Fog of Number 233.

With lightning speed, the Azure Mist Saint killed two seventh-tier calamity beasts, and the group then passed through a mountain forest.

As soon as they stepped out of the forest, the scene before them caused everyone to pause in surprise.

Just a few dozen meters outside the forest, there is an ancient city wall.

The city wall bears mottled marks, revealing the vicissitudes of time.

Inside the city walls, faint sounds could still be heard, suggesting that people were living there.

This made An Lan's eyes widen in astonishment.

He whispered, “Unbelievable. There shouldn’t be any base cities or other man-made cities in the Fog of 233. How come there are city walls here? And it even seems like there are people talking inside?”

An Lan looked at her mental pollution level detector and suddenly frowned: "That's strange..."

"What's wrong?" Saint Qinglan and the others all looked at An Lan.

An Lan's expression was somewhat solemn as she looked at the instruments and said, "The mental pollution fluctuations inside the city wall have been interfered with, and we cannot find the source of the pollution inside."

"What?" Saint Qinglan frowned immediately: "What will happen if the fluctuations are interfered with?"

An Lan thought for a moment and said, "There are mental fluctuations that have reached or exceeded the level of a Saint covering the city wall, or there may be abnormal mental pollution fluctuations caused by the special geographical location, or the city itself may be abnormal... In short, there are too many possibilities. Moreover, we know very little about the mist, and it may even be something that we are unaware of."

Upon hearing An Lan's explanation, everyone frowned.

Steve asked, "My Lord, Elder An, what do we do now?"

The others were also watching the two of them.

In this exploration team, Qinglan Saint is the captain, and Anlan, as a super intelligence awakener, is considered the team's strategist.

The opinions of the two individuals determine the direction of the team's actions.

Saint Qinglan frowned and looked at the city wall in front of him.

The city wall is about tens of meters high, and the material seems to be similar to that of the base city wall, but perhaps it is due to the corrosion of the fog, or perhaps it is due to the passage of time.

This section of the city wall always seemed rather dilapidated.

"Just by looking at it, we can't be sure what's inside the city wall. It seems to be the wall of a base city. Let's search along the wall and see where the city gate is; maybe we can find some clues."

An Lan nodded slightly: "The information we have so far is indeed insufficient, and we need to explore more clues."

Saint Qinglan hummed in agreement, his gaze sweeping across the area before he began to move along the left side of the city wall.

The sudden appearance of the city wall within the fog of No. 233 made Jerry and the others somewhat wary.

Everyone followed behind the Saint Qinglan, looking at everything around them.

As they walked, An Lan, who had been observing the city wall, suddenly spoke up: "There don't seem to be any guards on the city wall?"

The others realized what was happening too.

Normally, there are guards on the city walls of the base city.

They were only a few dozen meters away from the city wall, although from their current position they could not see what was happening on the wall.

However, if there were indeed guards, they would likely be stationed near the edge of the city wall.

That way they can see some things.

However, so far, they have not seen any guards at the edge of the city walls.

Not only that, they didn't even see the machine gun barrels or the soul crystal cannon barrels!

This should be an indispensable defensive force for the base city!

For example, during the beast tide in Base City 116, if those firearms hadn't killed most of the monsters and infected, Lu Ning wouldn't have been able to kill all the remaining monsters on his own.

It's strange that even these things are missing from the city walls of this base city.

They didn't know the answer, nor could they rashly jump onto the city wall to verify it; they could only continue forward with a sense of confusion.

They walked along the city wall for several kilometers without encountering any monstrous beasts or diseased individuals.

The mental pollution level detector malfunctioned on the side closer to the city wall, but remained intact on the side closer to the forest.

According to An Lan's investigation, the number of monstrous beasts and diseased individuals in the mountains and forests is also very small.

According to An Lan's guess, perhaps it was because the city represented by this city wall was extremely abnormal that the monsters and the infected chose to avoid it.

After walking for a while, the Azure Mist Saint in front of them suddenly stopped.

Everyone else stopped as well.

They looked ahead and saw the city gate.

Because they were positioned at an angle, they could not see the specific details of the city gate.

Therefore, the Sage Qinglan led everyone back into the mountains and forests, cautiously approaching the front of the city gate.

The city gates were wide open, with the base city's number displayed above them.

Base City No. 116.

Upon seeing the base city number, everyone's expression changed slightly.

Even Lu Ning, who is usually calm, was no exception.

"Base City 116?! How is that possible?! Base City 116 is clearly outside the fog!"

Steve stared in astonishment, his eyes widening, and gasped softly.

Jerry glanced at the city gate of the base, then looked at Lu Ning beside him: "...Lu Ning, do you know what's going on?"

Lu Ning shook his head: "I don't know."

An Lan, who was at the front, kept changing his expression, and then he shook his head: "This is not Base City 116."

Everyone else looked at An Lan.

An Lan pointed to the base city number on the city gate and then said, "We went to base city number 116 before, and I noticed that the number 6 on the base city number had broken signs. I guess it was left by some disaster before."

Upon inspection, everyone discovered that, just as An Lan had said, the number 6 on this site showed no signs of breakage.

Just as they were staring at it, the base city's number suddenly started to move.

Amidst the surging white fog, the base city changed from number 116 to number 121.

Before anyone could react, the number changed from 121 to 224.

The base city numbering changed faster and faster, eventually stopping at base city number 65.
