"Based on the limitations of the cognitive band, you must be careful. Some systems are too bloated and massive. If you choose the wrong one, and the compatibility is too poor, even a single thought could cost you years. It's too wasteful of your lifespan."

Qianyan Zhenjun advised.

However, what he said sounded like gibberish to Li Cheng颐. This was the trouble of lacking a background and heritage.

Many things that others considered common sense were completely incomprehensible to him.

In the path of cultivation, the most taboo thing is ambiguity. Although he could guess and deduce, if there was even a slight mistake during cultivation, it would be a huge danger.

Therefore, he must never make his own speculations when he didn't understand.

"Senior Sister, can you explain what the cognitive band means? And how do you judge compatibility?"

Thinking of this, Li Cheng颐 leaned slightly towards Que Ru and asked in a low voice.

He couldn't use spells or abilities here, and his mental power couldn't leave his body. He could only ask questions in a simple, straightforward manner.

"The cognitive band is a concept proposed based on the limits of our beings' cognition.

"Of course, it's a benefit." Que Ru continued, "If there were no King of Forgetfulness, all the information you learned would be stored in your memory. Over time, it would put a huge burden on yourself. It's like a pocket that only takes in and doesn't let out, it will be burst sooner or later. Information, even if it's intangible, has a corresponding material existence. The energy supply of living beings is limited. If this part is too much, it will squeeze out other parts, and eventually it will evolve into a deformed form that leads to destruction."

"My master hasn't been here," Li Cheng颐 answered honestly.

"That makes sense." Li Cheng颐 nodded repeatedly.

"However, any sense has its limits. Even if you indirectly research and understand through tools, there will still be a huge degree of distortion. Therefore, the cognition of living beings has a limited range. The first Yuan Ancestor of our sect defined this range as the cognitive band."

Using these senses, we explore everything, understand everything, study everything, and reconstruct everything."

"It's inherently troublesome." Que Ru said matter-of-factly. "Only with deep accumulation can one achieve effortless mastery. Accumulation and foundation must be extremely profound to be able to handle everything with ease."

His master, Yin Yue, was just an ordinary Zhen Bu Daoist. He wasn't qualified to come to the core inheritance area like the City of Silent Extinction.

"There's another point." The young man named Chun Fan also came over and added with a smile, seemingly out of nowhere.

"Yes, especially systematic forbidden knowledge. After absorbing it completely, an easification phenomenon will occur. It can evolve infinite knowledge and information on its own. You have to constantly absorb the newly emerging knowledge along with it. In this way, if you are not careful, you will be completely stuck, because there will be an infinite amount of new knowledge being evolved every moment."

Every step is logical and interconnected.

".So troublesome" After listening, Li Cheng颐 felt his whole body tingling.

Que Ru quickly reacted, realizing that the other party was a genius cultivator from the bottom, and looking at Li Cheng颐's simple (ignorant) eyes, she decided to build a good relationship.

"Leaving that aside, that's the scope of the ancestors' exploration. The cognitive band we need to learn includes two categories: forbidden knowledge and ordinary knowledge. Ordinary knowledge is bound by the King of Forgetfulness, that is, if you study for too long, if you don't review, you will forget it. This is the benefit of ordinary knowledge."

He originally thought that the Heavenly Gathering Pavilion was a cultivation sect. Now it seems that this is not cultivation, this is studying.

"As the name implies, it is all the areas that cognition can explore and touch. Relatively speaking, outside the cognitive band is the unknown band.

"Benefit?" Li Cheng颐 asked in surprise. "Forgetting is a benefit?"

"Didn't your master tell you?" Que Ru was a little confused.

"Knowledge that only goes in and doesn't come out, if there is too much and too complicated, it will cause you to automatically link countless pieces of information when thinking about a problem. Some information and knowledge may have contradictions, conflicts, or even connect to more information, thus causing yourself to get stuck."

If one is not careful and chooses the wrong one, it will be more than just troublesome.

Cognition is based on the senses, and the senses include mental power. In fact, mental power also has sensory organs, but you haven't observed it carefully before.

"Alright, choose. I hope you can find something that suits you, but there aren't many choices left." Que Ru sighed and walked forward, to a crystal pillar, carefully watching and thinking.

The young man Chun Fan also shook his head, sighed, gave Li Cheng颐 a look of self-help, and followed to the other side.

Li Cheng颐 calmed his mind, walked forward, and came to the first pillar.

Inside the crystal pillar, there was a silver crescent scepter.

The scepter was only the length of a forearm, like a child's toy, with delicate patterns and a surface that shimmered with fine silver light.

Below, flowing subtitles introduced basic information in black text.

'White Moon System: This system involves moon worship and has a mysterious connection effect with the moons in certain large dead corners. After in-depth research and understanding by one hundred and forty-two observation Daoists, it is believed that it can greatly improve the life's all-around qualities under the moonlight, and can temporarily travel through time and space, but has the possibility of losing control.'

'In as many as hundreds of thousands of cases, all living things that have learned the forbidden knowledge of this system can recognize any type of circle with gaps as the moon in the later stage, and stimulate their own special power. This power has been proven to be highly contagious.'

'In a completely open experiment, the White Moon system eventually polluted thousands of dead corners, and promoted the aggregation of all dead corners to form a giant white moon. The White Moon initially produced an extremely strong destructive consciousness, and its ability realm manifested between Saint-level and Dimensional-level. Over 90% of the testing Daoists believe that this system has higher potential. This is the marked evaluation here.'

'Strength: Four stars. Danger: Four stars. Difficulty: Five stars.'

Li Cheng颐 glanced at the star rating at the top. The highest was nine stars.

He looked forward, and there were two more crystal pillars in the middle that were not marked with names.

Temporarily placing the White Moon System in his heart, he continued forward to the second one.

Inside the second crystal pillar, there was a palm-sized, half-melted chocolate castle.

As for why Li Cheng颐 knew it was chocolate.

Because the introduction clearly stated it.

'Fairytale Kingdom: Preliminary observation of this system shows that those who learn its knowledge have the ability to turn anything into edible, sweet creations.

After hundreds of placement experiments, the observation Daoists confirmed that it can permanently change the surrounding space-time environment and turn everything into sweets. Then it will attract nearby living beings to devour the sweets.

All those who have eaten the sweets of this system will have parts of their bodies transformed into fairytale beings, and after leaving, they will see normal things around them as sweets, and have a strong desire to devour them.

In a completely open experiment, this system ultimately permanently changed seventy-six large dead corners, and ultimately led to the accidental death of thirty-two observation Daoists. Its estimated strength is likely to reach the complete dimensional level.'

'Strength: Six stars. Danger: Six stars. Difficulty: Seven stars.'

Li Cheng颐 frowned slightly. The previous one was much simpler, but this one was quite dangerous.

Although its strength was also stronger than the previous one, the strong uncontrollability made it clear that no one would choose this system.

He shook his head in his heart and continued to walk forward.

In the last crystal pillar in the middle, there was a white stone disk. The disk was similar to a sundial, with sharp pointers and a circle of precise and delicate graduations and symbols.

There were also many cracks and abrasions on the edge of the disk, as well as faint traces of blood, and it was not known whether it was blood or something else.

Li Cheng颐 looked at the introductory text.

'Eternal Life: This system involves enhancing the strength of the physical body. Inside a super-giant dead corner in the Black Sea, inside a primitive cave at an ancient point in time, a vegetarian wild bull accidentally swallowed a special fodder of mixed poisonous minerals, causing its physique to increase dramatically. The increase time was extremely short. More than thirty-two Black Sea minutes later, all the water in the wild bull's body dried up, resulting in death.'

'When the observation Daoists passed by the dead corner, they accidentally noticed its changes, extracted its remains, and tried to restore the process of death. It was finally discovered that in the millions of chain micro-particle reactions during the death process, some of the wild bull's cells showed a super-overload life force enhancement that far exceeded their upper limit.'

'In a completely open experiment, the life force increased according to this system can be accumulated and superimposed indefinitely, but it will bring a huge burden to the main body. And because of the particularity of forbidden knowledge, this enhancement is unique.'

"In the end, this experiment led to the complete annihilation of a medium-sized dead corner system, more than 700,000 dead corners were dissolved by excessive temperature, and the multi-dimensional tower dispatched several demon gods to cooperate with Ancestor Tian Qingzi to reshape cause and effect and restore the dead corner system."

'Strength: Nine stars. Danger: Nine stars. Difficulty: Nine stars.'

"."

Li Cheng颐 finally understood why no one chose this system. Just look at the difficulty and danger levels, and you can see how troublesome this system is.

He glanced at the other two sides. Chun Fan also looked helpless, while Que Ru had already made her choice and was talking to the guide, Qianyan Zhenjun.

Li Cheng颐 simply walked to the other two sides leaning against the wall and carefully looked at their crystal pillars.

There were still a few that could be chosen, but most of them had a strength of five or six stars, and the danger and difficulty were extremely high. There was even one with a strength of five stars, but the danger and difficulty had reached eight stars.

These were obviously the ones that were left over.

"Ahem. If you really don't want to choose, you can collect forbidden knowledge systems that you are interested in yourself. The Black Sea is boundless, and countless forbidden knowledge may be generated and disappear every moment. If you can record them and keep them in time, you can also increase the sect's heritage."

Qianyan Zhenjun said.

"After all, when you break through, or die, these systems can be left behind and passed down."

"." The three were silent.

After a while, Chun Fan broke the silence.

"Most of the forbidden knowledge is incomplete and fragmented. Collecting it yourself is like finding a needle in the Black Sea. Maybe you will be lucky and find a lot at once, or maybe you won't find all the fragments in tens of thousands or hundreds of thousands of years, because you don't know where the forbidden knowledge appears."

"That's right. A new knowledge evolution may flash by in a micro dead corner below you as you fly. Just that one percent of a second chain reaction, if you can't capture it, you can only wait for the next accidental evolution. The difficulty is too great, too great." Que Ru also shook her head.

"But the higher the compatibility, even if the strength is a bit weaker, it can exert strength beyond the star level, right? Look at our Ancestor Tian Qingzi, isn't that the case? The strength of the ancestor's system was only four stars at the beginning, but now that he has achieved omniscience, the strength has been forcibly raised to eight stars by his old man." Qianyan said with a dry laugh.
