Someone spoke timidly in the fog.

Hearing the voice, Bai Ling looked back.

Thanks to the seal, the obstruction of their vision by the white mist was greatly reduced, so they could easily see the people behind the mist.

She was a simple girl with long braided pigtails and black-rimmed glasses with lenses as thick as beer bottles.

She looked very embarrassed, with her hands folded nervously on her chest and her braid draped diagonally to one side.

Judging from her appearance alone, she looks like an academic girl who is immersed in her studies and completely ignores the outside world. Although it is a bit of a stereotype, there is no doubt that her plain appearance and innocent eyes give people a deeper impression of being "harmless".

However, none of the people present were ordinary people.

Not to mention Bai Ling, at least Xu Zhongxing and Xiao Liu became alert the moment they saw the girl.

They glanced at each other imperceptibly, and soon saw the same meaning in each other's eyes.

This guy in front of me... is a little suspicious! As an old man in the Countermeasures Bureau, Xu Zhongxing has experienced a lot and has a lot of suspicions. Even when he saw Bai Ling, he didn't trust him completely at the beginning. It was only after what happened later that he gradually confirmed that Bai Ling was not an accomplice of Paradise.

And Xiao Liu... as a person who graduated from a professional school, she was taught in school to be more careful about everything.

In fact, she did so. Up to now, she rarely expressed her own opinions. She mainly watched and listened more. Only occasionally did she disagree with Xu Zhongxing. Most of the time, she was willing to follow Captain Xu's arrangements. This was the valuable experience taught to her by the professional class.

On the battlefield against alien species, experience is more important than anything else.

So when they saw the girl in front of them, Xu Zhongxing and Xiao Liu did not move.

They just watched the girl approach silently, neither stopping her nor accepting her, but just watching and examining her coldly.

On the other side, the girl was probably a little "scared".

Her hands were shaking slightly, and her voice was trembling as well: "I... I heard your voices before, and thought there were other people like me, so I came over to take a look. I didn't... I didn't mean to scare you."

"My name is 'Han Jing', and I am... a student at Yanzhou No. 1 Middle School," the girl said in a trembling voice, "This is my student ID..."

As she spoke, she held up a certificate with both hands and showed it to the three people.

After taking a look, Xu Zhongxing nodded slowly: "This is indeed the student ID card of Yanzhou No. 1 Middle School."

His friend's child goes to Yanzhou No. 1 Middle School. He knows that only students and teachers have certificates for this school, and it is quite difficult to forge them. Nowadays, in order to prevent the threat of alien species, the production of many certificates must be reported to the Countermeasures Bureau. Therefore, there may be some "tricks" on the certificates that the parties involved are not aware of.

And Xu Zhongxing did see the "anti-counterfeiting mark" on this document.

At least this proves that there is indeed a person named "Han Jing" in Yanzhou No. 1 Middle School. But it is hard to say whether this "Han Jing" is the original "Han Jing".

Thinking of this, Xu Zhongxing turned his head and glanced at Bai Ling.

Bai Ling still carried out the methods he had always used, with an expressionless face, like a statue.

On the other side, the young girl Han Jing probably sensed the disbelief of the three people in front of her, and her voice became more and more trembling: "I just... heard your conversation. Ah, I didn't mean to listen, but there was no one else here except you, so I heard it accidentally..."

She twirled her clothes with her fingers. "You just said that someone might have been replaced. I don't think I was... replaced. Because you said that replacement requires playing game facilities. But I haven't played any facilities so far. It's always been my brother who has been operating..."

At this point, Han Jing's eyes dimmed. "I haven't exchanged my game coins either. I heard from the loudspeaker that if you exchange for an existing person, a 'fog' symbol will appear on the inside of your elbow. This means that a part of you has been exchanged, and a part of the existence is missing. When the existence completely disappears, the fog will... swallow you up."

As she spoke, she lifted up her sleeves, revealing her smooth, white arms.

Xu Zhongxing and Xiao Liu saw it clearly. Just as Han Jing said, there was not a single trace of marks on her arm.

And they...

All three of them slowly rolled up their sleeves.

Not surprisingly, they saw similar marks on their own arms.

Pulling his sleeves down, although he still didn't completely believe it, Xu Zhongxing at least smiled a little more: "Student Han, right? You said you were from Yanzhou No. 1 Middle School, so do you know XXX?"

That was the name of a class teacher in Yanzhou No. 1 Middle School, who was considered a minor celebrity in that school. Of course, if you were not a student in the school or had not spent some time in the school, you would never know this name.

It's like things in a small circle will only circulate within the circle, and people outside the circle basically have no chance of knowing them.

Han Jing was slightly startled when she heard this: "I've heard of her, but she's not in charge of our class, so I haven't seen her very often."

After hearing this, Xu Zhongxing nodded slightly.

Many things matched up, and it didn't look like a monster. After all, a monster couldn't possibly attend classes at Yanzhou No. 1 Middle School, let alone stay there for such a long time and remember an insignificant teacher.

The question now is, has the other party been "replaced"? There is no way to verify this.

To be honest, the question of whether or not you are still "yourself" is actually very difficult to prove if you are not familiar with it.

This is also why Bai Ling could only give some hints to the other two people, and could not use his ability to predict the future to find out the truth bit by bit.

It will take a long time to adapt to the replacement, but if you are not familiar with each other, who knows if the other party is abnormal. You may know what music your parents like to listen to, but you definitely can't know what flavor your neighbor's dog likes to mix.

This is still based on a relatively stupid and simple example. If a substitute is very thoughtful and intelligent, he/she may only need a few minutes to package himself/herself to be exactly the same as the original person. In this case, it would be difficult for close relatives or friends to tell the difference.

"Replacement" of memory is such a complicated thing.

"And we can't just leave it alone," Xu Zhongxing sighed, "If she was replaced, then we have to keep a close eye on her to prevent her from doing bad things in secret. After all, an open enemy is at least easier to detect than a hidden enemy."

If not...

Well, as a member of the Countermeasures Bureau, Xu Zhongxing certainly cannot just ignore ordinary citizens.

So in the final analysis, the best thing is to keep this person by your side.

Thinking of this, Xu Zhongxing turned his head and glanced at Bai Ling.

He was actually more worried about Bering's opinion.

According to Xu Zhongxing, Bai Ling is a person who is willing to give up everything to save his "sister". If a burden is added at such a time, will he agree?

When his eyes rested on Bai Ling.

Bai Ling also turned his head and glanced at Han Jing in front of him.

"According to what you said, you were not alone at the beginning?" He asked calmly, "What about the person who was with you? Where is he now?"

Hearing this, Han Jing's face became even sadder.

"He... was replaced," Han Jing said bitterly, "to protect me."

"Although we didn't know about the replacement at first, my brother felt that exchanging existence for currency was not a good thing no matter how you looked at it. So he decided that everything depended on him and that he would not let me enter the facility."

Han Jing: "At the beginning, my brother won a lot. According to the loudspeaker, we only need to win three times the amount to leave this paradise. But then, things started to go wrong. My brother kept losing, and in the end, not only did he lose all the coins he won, but he also..."

At the end, Han Jing's voice choked with sobs.

She covered her face, as if she couldn't bear to continue.

After seeing this expression, Xu Zhongxing and Xiao Liu softened their attitudes a little.

No matter what, at least Han Jing is still wearing a human face. Given Xiao Liu and Xu Zhongxing's personalities, it is impossible for them to be so hard-hearted as to have no reaction.

With a sigh, Xu Zhongxing said, "I understand. So, what do you want to do?"

Hearing this, Han Jing sobbed and said, "I...I just want to win my brother back."

"I don't expect to leave this place. We may never leave here again," she whispered, "so I won't do anything to you. All I want is to win my brother back - even if the two of us have to reincarnate in this place over and over again, it doesn't matter. This is my only wish."

"So my request is, if you want to enter any facility, just tell me a little bit about your experience. I won't take your coins. All I want is to hear your analysis, because my brain is not very good. If I just go in like this, I will never win..."

She stretched out her hand and revealed a seal: "And I also have this thing. It is because of it that I can travel through the white fog. If you need it, I can give it to you..."

Hearing this, Xu Zhongxing's originally vigilant heart relaxed a little again.

This condition can be said to be very harmless.

Han Jing will not influence their actions, but just wants to listen to their analysis, which can almost be said to make her a "stone" that cannot have any influence on them.

If he is really a "cohort", he will certainly encourage them to participate more, or make suggestions that seem to solve the problem but actually make people fall deeper into the trap. He will not be as obedient as a rabbit as he is now.

Not to mention that she was able to give up the seal.

You know, the "tourist area" is scary, and even the ghosts are afraid of it. Otherwise, how could the investigator who was replaced by the "ghost" disappear without a trace after entering the tourist area? It seems that this guy is not necessarily a ghost.

After figuring this out, Xu Zhongxing looked at Bai Ling: "Mr. Bai, what do you think?"

Bai Ling looked at Han Jing indifferently.

What a bad taste, paradise.

He thought to himself.

It can be said that Paradise really doesn't want to influence their route.

Because as long as they continue to play this game, Bering and the others will inevitably go to the location of the "Fog of Chaos".

According to Bering's observation of the future, if he did nothing and just followed, then after playing some facilities, they would be panicked to find that the seal would have an extra mark for each facility they played. Once the seal's mark was filled, the original effect of resisting the white fog would disappear.

The "tourist area" would open its bloody mouth to them after they completely lost the protection of the seal! Of course, the final result was that Bailing easily crushed the head of the "dangerous" alien, but because of his move, Paradise escaped with the "chaos fog" without even letting Bailing smell the exhaust.

And if Bai Ling intentionally manipulated the route and made them go in the direction of the "Mist of Chaos"...

Xu Zhongxing and his companions would notice that as the journey progressed, their existence became increasingly sparse. In the end, even the ability to maintain physical movement was gradually disappearing.

This is because the exchange of "existence" depends on the fog of chaos, and the currency exchange in the park is just a means of using the fog. Therefore, the closer to the fog of chaos, the more obvious the weakening of this existence.

Bai Ling was fine, he was not a living person, so he was not too worried.

But Xu Zhongxing and his friends were in a miserable situation.

In many futures, Xu Zhongxing and the other person were gradually losing their existence until they were completely reduced to food for the fog of chaos.

But in these futures, when Bering stood before the fog of chaos, paradise was already far away from him.

The monster probably saw that the existence of the Chaos Mist had no effect on Bailing, so it realized something was wrong during the journey and ran away quickly.

It really made Bai Ling sigh at his caution and timidity.

"So, the goal now is to send Xu Zhongxing and the other person to another place, while I and Le Yuan will move forward together."

Stroking his chin, Bai Ling came to a conclusion.

Paradise probably wants him very much, which can be seen from countless observations of the future.

She even made up a story about a sister saving her brother just to verify Bering's situation and gain his empathy.

Although it was a bit old-fashioned, the performance in the park was good. At least Xu Zhongxing and the others next to her were fooled by her and believed it to be true.

But Bering was not so easily fooled.

Glancing at Han Jing's white elbow, Bai Ling sneered in his heart: "Of course you didn't exchange for existence."

Because this is your backyard, why do you need to do this?

As he spoke, he calmly wiped off the black ink pen on his elbow.

Bai Ling did not exchange for existence, so this thing was secretly written by him with a black pen in the secret realm.

It was very simple and very realistic - at least Le Yuan would never have thought that someone would draw the mark exactly on their elbow before seeing it.

It can only be said that the level limits the imagination of the park.

After hesitating for a moment, Bai Ling stretched out his hand.

He grabbed Han Jing's shoulders and said to Xu Zhongxing, "Captain Xu, I think we can bring her along."

"I think my sister probably has the same idea as her. So, I can understand her," Bai Ling said.

Such words made Xu Zhongxing nod slightly.

However, the next second, Bai Ling's words made him a little overwhelmed: "So, I think we should act separately now."

He took the seal from Han Jing's hand and threw his seal to Xu Zhongxing. "Miss Han and I share the same view - I want to find my sister, and she wants to win back her brother. There is no conflict between us. It is completely mutually beneficial. I can help her analyze the process of finding her sister, and she can also help me find clues."

"You two are here to alert our companions outside and to rescue others. Under such circumstances, we are actually in conflict. After all, we can't always fight against the people in the park. If there are any projects that require collisions, such as bumper cars, then we will inevitably fall into meaningless internal friction."

At this point, Bai Ling looked at Xu Zhongxing calmly: "So I think we should separate temporarily. This has many advantages. At least Le Yuan will be too busy to handle everything. We didn't see Le Yuan before, probably because he was taking care of other contestants. This proves that he can only interfere with one person at a time, so after we separate, we can put Le Yuan in a difficult situation to choose."

"Besides, we still have two seals. If we separate, we will be able to explore a larger area. To sum up, I think it is best to start separately."

Look at Bai Ling's face.

Xu Zhongxing was silent.
