Looking at the back of the tall and short, black and white gradually disappearing under the sunset, three big question marks popped up on Chen Fan's brain.

I don't know why, but I always feel that the black-robed priest named Isha is a little dumbfounded.

Is it a delusion?

Those who can become priests can't be so stupid, right?

Chen Fan shook his head and left the confusion in his heart behind.

He took a deep breath and walked towards the low-rise residential building.

As he ascended the stairs, he glanced quickly at the open window.

In the dim incandescent light, a believer was kneeling in front of the idol and praying with a reverent expression—at least in Chen Fan's opinion.

After walking a few steps, Chen Fan came to the door of his house.

The door was closed, and a faint dim light came out of the cracks.

He subconsciously turned his head and glanced at the door of Xu Huai's house next door.

Just like at home, the door is closed, and there is not even a light.

He took a deep breath and was about to knock on his door as soon as he raised his hand when it opened.

Behind the door, his mother, whose eyes were a little red and swollen, looked at him as usual: "Xiao Fan, are you back?" ”

……

After returning home, Chen Fan followed his mother through the standard process of praying to the goddess again.

After a day in the main church, Chen Fan was already very familiar with the process.

After the prayers, it was time for dinner.

At the dinner table, his mother calmly talked to him about his daily routines, and at the same time asked him something about the third oracle.

It would seem, everything is business as usual.

Chen Fan didn't know his mother's psychological state at this time, but ......

In the face of the church, hiding his identity twice in a row actually shows the attitude of the mother!

Although he was a little unbearable in his heart, reason told Chen Fan that maintaining this state was only good for him!

Not only that, but he should even use this delicate relationship to his advantage!

He froze and looked as usual: "Mom, there is something I want to ask you." ”

The mother's hand moved slightly, and she turned her confused gaze to her child.

"It's about the city of Varela, ...... outside the city"

Before Chen Fan finished speaking, his mother's face had changed greatly: "Wait! ”

The mother's face turned her head to glance at the statue of the goddess not far away, and after noticing that it did not move, her demeanor recovered a little.

Her face changed several times, and finally as if she had made a decision, she got up and walked towards Chen Fan's room.

"Xiao Fan, this is not the place to speak."

"You come with me."

……

Mother stretched out her hand and closed the door to the room, completely blocking the idol in the living room: "If I'm not mistaken, you just wanted to ask about the situation outside Varela, right?" ”

Seeing Chen Fan nodding, his mother sighed softly.

She hesitated for a moment: "I don't know what happened to you in the room in the last few days, but I still believe it...... You're still my child. ”

Chen Fan's heart trembled.

Well, there's no need to doubt it now.

One is right, his mother has indeed noticed his abnormality!

She didn't give Chen Fan a chance to speak, and said to herself:

"Little Fan, this is a topic that the church strictly forbids."

"Remember, don't discuss this in front of the idol!"

There was a hint of horror in the mother's somewhat cloudy eyes: "In this building, there was once someone who was sent to the church's execution table by the church because of this incident. ”

She froze, and then said:

"As for the ...... outside of Varela"

"That's where the sinners live."

Chen Fan was a little surprised: "Sinners? ”

"They are not protected by the goddess, they are eternally cut off from the city of Varela, and they are tormented and corrupted by the filthy breath for the rest of their lives."

The mother sighed: "Of course, this is also a rumor I heard,"

"As for what the real situation is...... I'm afraid no one knows. ”

"Can't you just go out and have a look?"

"Get out?" Mother shook her head, "There's a wall of sighs in the way, no one can go out, and no one can come in." ”

"Wall of Sighs?"

"It was a miracle from the goddess of the first year of the Varela calendar, which surrounded the entire city of Varela, and completely blocked the filth from the outside world."

“……”

……

"One, can a wall block nuclear radiation?"

After his mother left the room, Chen Fan asked Yi for confirmation with some confusion.

[It's a bit difficult.] 】

One quickly gave an answer.

Unless this wall envelops the entire city of Varela. 】

At the same time as the words fell, a blue hologram automatically appeared in front of Chen Fan's eyes.

In the image, a huge city is slowly covered by a huge hemispherical dome.

From a distance, it looks like a small mound lying on flat ground.

Looking at the simulated scene in front of him, the corners of Chen Fan's mouth twitched: "Impossible!" When pigs fly! ”

He also witnessed a round of sun hanging in the sky during the day, could it be that the sun was fake?

No kidding!

"But then again."

"Is this radiation so difficult to deal with?"

Chen Fan, who had been living in a peaceful era in his previous life, only stayed at the level of "hearing about nuclear weapons".

Nuclear radiation is mainly divided into three types of radiation: α, β, and γ. 】

[Among them, α rays are helium nuclei, and their penetrating ability is very weak, so there is basically no need to consider it.] 】

[β rays are a stream of electrons, which has little penetrating power, and the skin of the human body will be burned when it is irradiated, which is consistent with the description of the disaster. 】

[As for γ rays......]

[That thing is quite penetrating, and for low-level civilizations, it can only be blocked by natural materials with the highest density possible, usually with substances such as lead.] 】

"What about the higher civilizations?"

Chen Fan asked curiously.

[With the help of space shield or dimensional shield, you can resist γ radiation at the level of gamma-ray bursts, not to mention some radiation caused by nuclear war.] 】

But this thing isn't something you should be thinking about right now. 】

"Okay." Chen Fan, who was invisibly shown off, shrugged his shoulders indifferently, "You continue." ”

[In addition, there is a key piece of information.] 】

[This machine carefully analyzed the information in the database and found a phenomenon. 】

[For low-level civilizations, nuclear radiation is not the greatest hazard of large-scale nuclear war. 】

"Huh?"

At this time, Chen Fan was really shocked: "What is the reason for this?" ”

[Normally, the nuclear weapons used in large-scale nuclear wars are hydrogen bombs. 】

[Compared to the atomic bomb, the radiation effect of the hydrogen bomb is not large.] 】

[The aftermath will only last for a few years or less.] 】

Chen Fan nodded thoughtfully.

He understood the meaning of the words.

"You mean...... This wall of sighs is nothing more than a gimmick? ”

"It can't block the nuclear radiation from the outside world at all, and its purpose is just to prevent the believers in Varela from leaving the city?"

"It's like ......"

Chen Fan's brows furrowed slightly, and a flash of inspiration flashed in his mind: "It's the same as keeping believers in captivity in the city!" ”

[There is a high probability that this is the case.] 】
