After leaving the Sword Pavilion, Yin Feng returned to his cabin, some dust had accumulated in the house, thinking that after he left, there were few people here, and he could see that this place was indeed remote enough.

There was a letter on the table, Yin Feng walked over and picked it up and looked at it, the handwriting was very beautiful, it was left by Mu Gen, the content of the letter was not long, but it was concise and to the point, and the content to be expressed was very clear.

"I didn't expect that Mu Gong had returned to the inner peak, and his heart must have been extraordinary. ”

Yin Feng smiled bitterly, he wanted to come back and clean up and go to the spirit beast area to find Mu Gen, but he didn't expect that the other party had already left, and while smiling bitterly, he couldn't help but feel a little lost in his heart.

Sun Ren, Mu Gen, and Li Wan, the three people who have the best relationship with him, are not in the North Outer Gate now.

"It's just the right time to concentrate on improving your cultivation. ”

Yin Feng's eyes were scorching, and he had the urge to do a big job, and now his spiritual spring was very stable, as long as he tempered his state of mind to be flawless, he could start to improve his cultivation.

Three days later, Yin Feng, who was sitting cross-legged, slowly opened his eyes, his eyes were confused, he thought that he could temper his state of mind flawlessly with the help of Yaolan Sutra in two days, but this is the third day, and he is still hovering in place, and the last trace of negative shadows, like maggots attached to the bones, is difficult to eradicate.

"Look, isn't that Senior Brother Zhuo, why did you become like this?"

"I'm afraid you don't know yet, Senior Brother Zhuo was just released from the small dark room and stayed in it for three days!"

"Oh my God! Three days! Staying in that horrible place for a moment is worse than death, I don't want to go there for the rest of my life!"

Far away, Yin Feng heard the conversation of several disciples, at this moment he hid his aura very well, he didn't want to be discovered, for fear of causing an unnecessary sensation, this time he came out mainly to distract his mind, after all, tempering the state of mind is such a thing, blindly doing it will never work.

I didn't want to see this scene, but I saw that the monk surnamed Zhuo was supported by two law enforcement disciples, his face was full of sweat, and his expression was extremely depressed.

This monk surnamed Zhuo was one of the ten people who captured the most mortal slaves in the North Outer Gate, and the punishment he received was not only to pay 3,000 spirit coins, but also to face the wall in a small black house for three days.

It's just that the ten people seemed to have heard something and kept wandering outside, but this monk surnamed Zhuo was unlucky and was tied up by Yin Feng.

"There is no injury on the whole body, and the cultivation breath is also very stable, why does the expression become like this, is it the state of mind that is punished?"

Yin Feng stroked his chin, quickly sorting out all the information about the little black house in his mind, the more he sorted it out, the brighter his eyes became, and then he seemed to have made up his mind, and quickly walked towards the torture hall.

"What? You're going into the little dark room?"

In the torture hall, Elder Zhou's face was full of incredulity, this small black house can be said to be the most terrible criminal law in the North Outer Gate, and others heard that their colors changed, but they didn't expect this Yin Feng to take the initiative to go in by himself.

"Yes, I watched all the disciples in the door talk about the change of color in the little black room, I am very curious, I want to enter and see, what others are afraid of, I don't necessarily have to be afraid!"

Yin Feng said very seriously, and his expression was neither humble nor arrogant.

"Yes, that's right! It's not life-threatening anyway, and since you want to experience it, I'll promise you. ”

Elder Zhou smiled heartily, his eyes were full of approval, and then he summoned two law enforcement disciples and took Yin Feng to the small black house.

......

"Look, isn't that an undefeated senior brother, how can he follow the law enforcement disciples, did he make any mistakes?"

"No, don't you think they're going in the direction of a small black house?"

"Oh my God, the undefeated senior brother was punished the most severely and was taken into the small black house. ”

Some of the disciples who were passing by happened to see this scene, and they all had a heated discussion there.

In fact, not only the passers-by and disciples looked surprised, but the two law enforcement disciples who led the way had strange eyes, and others regarded the small black house as the abyss of hell, this guy was good, but he asked to go in.

Obviously, Yin Feng's entry into the small black house once again caused a sensation at the North Outer Gate, in fact, there were not a few disciples who were punished into the small black house at the North Outer Gate, but the reason why Yin Feng caused a relatively large movement was purely a celebrity effect.

Those disciples who had a festival with Yin Feng, such as Shen Lang, Shen Qing, Shi Tong and others, were all gloating, secretly praising the heavens for having eyes.

At this moment, Yin Feng looked at the black boulder in front of him in a daze, the boulder space was hollowed out, and the whole was like a stone room, and the stone door of the stone room was wide open at this moment, obviously there was no one else inside.

"Undefeated Senior Brother, there is a small black house, usually we personally bring the punished disciples in, and press the gate before leaving, but you are different, we will leave. ”

After the two law enforcement disciples greeted Yin Feng, they left with their fists clenched.

Yin Feng looked at this small black house, from a long distance he felt the energy fluctuations coming from the boulder, which was depressing and uncomfortable, he guessed right, the energy transmitted by this small black house can indeed act on the state of mind, and many things that are afraid of the subconscious will be invisibly amplified, such as a mountain of swords and a sea of fire.

The moment Yin Feng walked into the small stone house, his heart sank suddenly, as if a 10,000-pound boulder was tied to his heart, and his body bent down involuntarily.

"It's terrible!"

Yin Feng's eyes were shocked, and he slowly straightened his body, and then he pressed the door gate, because Yin Feng felt that this would make the energy in the stone chamber more condensed.

Sure enough, at the moment when the gate fell to the ground, Yin Feng felt that his heart was going to be dragged to pieces, in fact, there was no force acting on Yin Feng's body, there was only a hazy halo around him, swinging like water waves, but it was this seemingly soft energy that could make people suppress to the point of collapse.

"What kind of power is this, it is so magical. ”

Maybe it was because Yin Feng's state of mind was not far from reaching the perfect realm again, so his eyes were still clear at the moment, but he felt that his heart was tense and uncomfortable, and there was no terrible illusion coming.

However, as time passed, Yin Feng could feel that his mood was fluctuating more and more, and the reason why he felt that this power was magical was because this energy seemed to be an invisible sieve, filtering through his state of mind.

As time passed, the filter pores of the sieve were slowly getting smaller, and sooner or later the last trace of dirt in Yin Feng's state of mind would be filtered out.

This is undoubtedly very different from the effect of the Yao Lan Sutra, the Yao Lan Sutra just gave birth to a fire in the state of mind, thus burning the dirt and dust on the state of mind, which is very domineering and direct, but later, as Yin Feng's cultivation became higher and higher, the dirt accumulated on the state of mind was almost difficult to be completely refined.

For example, this time, Yin Feng observed the Yaolan Sutra for three days without any progress.

Tempering the state of mind does not mean that it is necessary to get rid of all the bad shortcomings, to become a saint and become a Buddha, the dirt and impurities on the state of mind are just the traces and shadows left by the dark side, there is no need to abandon the dark side, just wipe off the traces and shadows left by it, if all the dark side is removed, then Yin Feng is not Yin Feng.

In the small stone house, Yin Feng sat cross-legged, his face was very pleasantly surprised, because he felt that the energy of the small stone house was the best help for tempering the state of mind, it was very orthodox, not comparable to the Yaolan Sutra, it could be said that this small stone house was simply a holy place for tempering the state of mind, but it was a pity that the North Outer Gate actually used it to punish disciples.

At this time, a day has passed, and many disciples of good deeds are waiting far away, but until now, there has been no terrible roar coming from the small black room.

At this moment, Yin Feng didn't know anything about the situation outside, he closed his eyes tightly and waited in peace.

"It's coming!"

Yin Feng's expression was overjoyed, and he saw that a little black shadow on his state of mind was filtered out, and the energy that was wandering around suddenly churned, as if a hungry wolf had seen its prey, and instantly became fierce and brutal.

And this dark shadow in the state of mind was magnified countless times in an instant after encountering this energy, and emotions such as depression, fear, pain, and despair instantly filled Yin Feng's entire heart.

"Ahh

Yin Feng roared angrily, he felt as if he had fallen into the Boundless Purgatory, with piles of corpses and bones.

Unlike the refining effect of the Yao Lan Sutra, those mood impurities are often burned out in an instant, so there is no chance to experience the horror of these impurities.

Yin Feng's face was pale, his whole body was soaked, and he felt that everything had gone up and down the sword mountain and the sea of fire, this time he finally understood why those disciples were afraid of the little black house like this, this was indeed an inhuman experience.

Yin Feng also knew that he must not faint like those disciples in the past, because if he fainted, his previous efforts would be wasted.

As time passed, those painful visions finally slowly dissipated, Yin Feng opened his eyes, a smile in his eyes, and his state of mind was finally perfect again.

Outside the small black room, a sharp-eyed disciple suddenly said, "Look, the undefeated senior brother has come out." ”

"It's been three days, why didn't he faint, he actually walked out on his own, incredible!"

"The undefeated senior brother has an amazing physique, and cross-level battles are like eating and drinking, which is naturally different. ”

"But you look at his face and his clothes, and it seems that he has suffered a great deal of sin, and this little black house is indeed the most terrible place. ”

......

Seeing a lot of people outside the small black house, Yin Feng's figure immediately flickered, and he immediately disappeared without a trace, he didn't want to be surrounded by a circle of people asking for autographs again.

After returning to the cabin, Yin Feng fell asleep, but fortunately, Wu and the elders were worried that Yin Feng would be disturbed and affect his cultivation promotion, so he set the remote woods where the cabin was located as a forbidden place, otherwise Yin Feng would not be able to sleep peacefully.

Ten days later, a trace of red brilliance flashed on a remote hill, Yin Feng's figure appeared in the clearing out of thin air, put away the desolate ding, Yin Feng wiped the remaining spiritual essence at the corner of his mouth, and the juice in the spiritual peach remained.

"Finally the eighth layer of the foundation realm has been built!"

Yin Feng was very satisfied, everyone else was a small realm step by step, and they had to go through the early, middle, late, and peak steps to cross the threshold of the big realm in one fell swoop. And Yin Feng didn't need to step on his feet at all, so he jumped over and jumped over.

Yin Feng once again realized that the physical cultivation with sufficient heavenly and earthly treasures was really refreshing, and he felt that the cultivation realm was just a derivative of the body after it continued to become stronger, and for the law cultivation, the strengthening of the body was just an incidental product of the cultivation of the realm.

From this point of view, the two are undoubtedly completely reversed.
