Dim lights illuminate the dull road ahead.

The invisible pollution that spreads in every inch of space is like a dull drum beating in people's hearts, one after another.

Zhang Yusi raised her head and glanced at He Ao in front of her, then lowered her head and looked at the blood-stained road under her feet.

They had only walked out a hundred meters, and the corridor they saw was basically an empty area that had been destroyed, or electronic equipment that had been completely damaged.

During these more than 100 meters, Zhang Yusi deeply realized the meaning of what He Ao just said, "Pollution is everywhere."

With the death of the sea anemone monster, the strong impact of pollution also disappeared. For a short time, Zhang Yusi thought that everything would return to the way it was before she was polluted.

But as time passed, she gradually realized that people still can't be too naive.

If there is a loud noise ringing in your ears, the small noise will be undetectable.

And when the noisy noise disappears, for a short period of time, people will feel that the world has become quiet.

But the world will not be quiet. The subtle noise still echoes in the ears, and as the surrounding environment quiets down, it becomes more abrupt.

Zhang Yusi is in this state now.

Every few steps she takes, the world in front of her will flicker briefly, and some illusory images will be superimposed on the real scene, disrupting her perception.

Sometimes she would hear some inexplicable calls or laughter, and sometimes it would be like passing through a densely populated vegetable market, but there was no corresponding noise in this bustling market. It was as quiet as a ghost land, and when she walked through the market

At that time, it seemed as if someone was whispering in her ear.

These 'things' did not deliberately guide her perception as just now, and many times, they were even fleeting like flashbacks.

But this chaotic scene made it increasingly difficult for her to distinguish between reality and fantasy.

For a moment, she thought it was all a dream, and she was still doing boring experiments in the small laboratory in Beidu.

The absurd illusion in front of us is not some ruins or pollution, it’s just that

It's just that she's crazy.

In this superposition of reality and illusion, this short distance of one hundred meters seems as long as a marathon.

"Clear distracting thoughts, don't think about anything, don't think about anything."

The calm and calm words pulled Zhang Yusi out of her chaotic thoughts.

She raised her head and looked at He Ao's back in front of her.

He Ao did not look back, but continued to move forward at a steady speed. His pace was steady, and each step was like the sound of a bell from an ancient mountain temple, calling Zhang Yusi back from the chaotic and crazy thoughts.

"Calm down and don't doubt yourself,"

He Ao continued, "Don't think about what those chaotic things are. These mild pollutions can improve your ability to discern, because they do not create a completely 'real' illusion. You can still discern

What is reality and what is illusion? Grasp the reality and stabilize your thoughts."

He Ao turned around and looked at Zhang Yusi, "The most important thing is, never forget who you are,"

He turned back and continued forward, "If you encounter pollution that you really can't resist, just imagine that you are an idiot who can't think and only remembers your name. Although you may become a real idiot, an idiot is

He who has a name will never forget who he is."

"Um!"

Zhang Yusi nodded in understanding.

Following He Ao's footsteps, she began to empty her mind and search for the characteristics of the real world in the flashing weird illusion.

In fact, as long as we have the right direction, the characteristics of the real world are not nowhere to be found.

Because Zhang Yusi has a basic understanding of the real world, this understanding anchors her thinking, allowing her brain to naturally come up with what the real world should look like.

Which scenarios are illogical or should not occur.

For example, what just flashed before her eyes was a pale little boy holding a balloon running towards her in this dark ruins environment.

This kind of thing is illogical.

In addition to scenes and phenomena, she will also summarize issues of her own perception, such as which whispers are not ringing in her ears, but ringing in her mind and should not be uttered, and whether the wind blowing across her arms is real.

The wind is still a sudden hallucination.

All these made her understanding of the real world clearer.

The illusions that affected her had not disappeared, and the things that interfered with her cognition had not been hidden, but her mental and thinking state had become increasingly clear.

She has been able to gradually find the boundary between reality and illusion, and has begun to figure out the secret to maintaining her mind.

Stay focused and think less.

Of course, this reduction of thinking does not mean giving up thinking uniformly, but when illusions appear, try to maintain the concentration of thinking, and maintain a higher frequency of thinking when you are in reality.

Although this method was a little uncomfortable at first and difficult to get used to, she quickly adapted to it due to the extremely high thinking ability of the 'researcher'.

Her steps, which had been somewhat heavy and slow, gradually returned to briskness.

He Ao, who was walking in front, breathed a sigh of relief when he heard the brisk footsteps.

In fact, the method of simplifying thinking to resist pollution is mentioned in the FBI training. The FBI requires investigators to keep their thinking as simple as possible when facing pollution erosion, which can reduce the chance of being contaminated and maintain sanity.

The idiot method can be said to be an extreme case of this simplified thinking method, that is, when faced with irresistible pollution, give up all thinking and imagine that you are an idiot who only remembers your name, in order to improve the survival time of your sanity.

Although in that extreme case, this method actually doesn't make much sense.

The method that He Ao taught Zhang Yusi is not simply a method of simplifying thinking. The effect of that simplified method is actually much weaker when resisting this kind of high-level pollution, because under this level of pollution and interference, it is not

If the polluted person wants to clear his mind, he can do so.

Those messy babbles will naturally give rise to messy thoughts.

So in the face of this situation, resistance is actually better than avoidance.

And the only thing that can resist thinking is thinking.

So in addition to teaching Zhang Yusi to 'simplify', He Ao also deliberately guided her to 'focus'.

In fact, this method of guiding concentration is an immature method of resisting pollution.

This method does not come from the memory of the dungeon character, but was derived by He Ao himself after reviewing Jace's experience.

Jace is a very special "copy character". His specialness does not lie in his experience, but in his state.

He was facing direct pollution from a high-ranking being anytime and anywhere, and he even had crazy thoughts in his mind.

But he is not crazy.

In fact, in a sense, Jace is equivalent to a 'demigod'. Although he is very weak, he can directly enter madness to spy on the truth.

Although he cannot maintain basic thinking in a state of madness, nor can he truly control the state of madness, nor can he remember the truths he has seen.

But he can still use his weak body to pry into the bottom truth of the world, and, being so close to the truth, he is not crazy.

Relying on his love for the once beautiful world and his hatred for the mysterious man, Jace still maintained his last sanity amidst the deepest madness.

This reminded He Ao of a kind of existence, an 'angel'.

In Yin Lian's underground library in Rock City, He Ao once read a book called "The Glorious Sanctuary".

It is mentioned that all angels are indescribable monsters and minions of gods.

But among the knowledge he knew, the counterexample to this conclusion was the Legion Commander of Chenxi City, an angel who maintained his human form.

In the later murals that recorded the history of the Fountain of Youth, He Ao also saw the footprints of a humanoid angel. The angel who claimed to be a "wizard" buried the Fountain of Youth after defeating the puppet controlled by the Fountain of Youth.

In other words, at least at the end of the catastrophic era in the dungeon world, some people have mastered the method of promotion without turning into monsters.

Howe didn't know what was the reason that eventually turned all the original angels into monsters, but he didn't rule out the influence of those crazy world truths.

And Jace is the one who has resisted the pollution of these truths.

And his method of resisting pollution seems to be an obsession that cannot be eradicated.

However, this kind of obsession cannot be copied, and He Ao does not want to copy it, so he tried to weaken it based on the properties of this obsession, and then based on the experience of previous characters and the core principle of simplifying thinking, he summarized this

A focused approach.

After all, obsession is also a kind of ultimate concentration in a sense.

Of course, he didn't know whether this method really worked.

So he combined this method with the method of simplifying thinking and told Zhang Yusi.

Of course, he did not directly tell Zhang Yusi to focus. Inexplicable concentration is ineffective. There must be a definite focus that can guide one's true thinking.

He Ao took a clever trick and set this focus into the real world.

Zhang Yusi, who was tortured by pollution, longed for a real and peaceful world. He Ao guided her to this desire so that she could concentrate better.

In fact, it doesn't matter where you focus. What's important is to stay focused in the true sense, to maintain an almost obsessive focus on what you desire.

The final result was somewhat beyond He Ao's expectations.

Zhang Yusi's talent sequence is very powerful in improving her thinking ability. In addition, she is very smart, so she quickly understood the key to concentration and dynamically controlled her thoughts.

In a short period of time, she adjusted herself out of the contaminated state and became more and more sober.

He Ao originally thought it would take some time to see the effect.
