180.

Each of the major realms of a cultivator can be divided into four small realms.

For example, the Qi refining period is divided into, primary, intermediate, high, and consummating.

Then, when a cultivator cultivates to the limit state of perfection in the small realm, he can touch the barrier of promotion between the large realms, and compared to the barrier of breakthrough in the small realm, the barrier of promotion in the large realm is also called the barrier of the barrier.

Cultivators use the word Heavenly Trench to describe the difficulty of breaking through the Great Realm.

When a cultivator touches the Heavenly Barrier at each level of the Great Realm, it means that he has reached the extreme state of this Great Realm.

That is, fire, after the primary, intermediate, high, and consummation, there is also a limit state.

However, unlike the previous four realms, the limit state does not belong to a separate realm.

The reason is that after entering the limit state, there will be no increase in the condensation of the Tai Chi cyclone.

When Cheng Li sensed that the Tai Chi cyclone had solidified, he felt that it was about to drip out.

A barrier that can clearly see the entity was generated from the Taiji cyclone, and then it quickly dispersed in the dantian with the momentum of overwhelming the mountains and seas, blocking all the spiritual power flows that were about to rush into the middle of the dantian.

Cheng Li could sense that at this time, the Taiji cyclone was already at its limit, and I was afraid that as long as a little bit of spiritual power flow was injected, it could cause qualitative change from quantitative change to qualitative change, and a qualitative transformation would occur.

But at this time, because of the existence of the Chongguan Heavenly Trench, all the spiritual power flows were not allowed to enter it, and they could only stare dryly outside.

Moreover, Cheng Li's divine sense could perceive that this barrier was at least ten times stronger than the previous barrier.

The previous barriers to rushing through the customs were all invisible.

And now that this Chongguan Trench has been substantiated, Cheng Li's divine sense can clearly "see" the golden barrier, which is like a trench in the middle of his dantian, wrapping the Taiji cyclone in the middle in all directions, and there is no gap to enter.

Cheng Li originally wanted to try to impact this Chongguan moat.

However, as soon as this idea came to mind, I heard the little boy say crisply: "It's time for epiphany!"

The voice of the little arithmetic boy interrupted Cheng Li's thoughts, freeing Cheng Li from his cultivation state, and the pillar of light was also stripped from Cheng Li's body and retreated back into the arithmetic monument.

Although the state of epiphany was lifted, Cheng Li still closed his eyes a little unsatisfied, as if he was still experiencing the harvest when he had just had an epiphany.

Because in the state of epiphany, cultivation is completely automatic, so Cheng Li's consciousness is not much focused on cultivation.

In fact, most cultivators, in the state of epiphany, the biggest gain is in the state of epiphany, and the affinity of the human avenue is the strongest, and in the state of epiphany, it is especially easy to have some enlightenment gains, which is far more important than the cultivation that can be accumulated over time.

Cheng Li is a rational person, so he didn't gain any insight into the avenue.

However, just in the state of epiphany, Cheng Li gained something far more important than understanding...... That is the condensation of knowledge!

In the state of epiphany, people's mental agility is much faster than usual, and they are more intelligent and active.

In the past 9 hours, Cheng Li has been doing problems on the arithmetic tablet, and has reviewed the mathematical knowledge he has learned in the past ten years.

Originally, in this process, although Cheng Li kept learning through it, the time was too hasty after all, and there were many knowledge points, which Cheng Li did not digest well, and it was a little scattered.

However, in the process of this epiphany, Cheng Li put most of his thinking on the 2,000 questions he had done in the past 9 hours because his cultivation was fully automatic.

In the process of sorting out such memories over and over again, due to the super bonus effect of epiphany, Cheng Li is equivalent to putting the past 9 hours ...... No, it is a deep condensation of all the mathematical knowledge that Cheng Li has learned in the past ten years!

What's more, what makes Cheng Li feel even more amazing is that he feels that he is in a state of epiphany, with endless inspiration.

Many scientists and mathematicians, when compiling some theories, in the most difficult and critical time, in addition to relying on the usual accumulation, sometimes more importantly, rely on the ethereal flash of inspiration, that is, inspiration!

According to Shutong, these inspirations are some kind of high-dimensional information mapping, and when scientists and mathematicians are writing theoretical works and thinking about difficult problems, the brain is in a state of super-active thinking, and the brain waves are high-intensity and elegant. At this time, these ultra-highly active brain waves are particularly easy to receive some high-dimensional information mapping, which is reflected in people's minds, which is a flash of inspiration, and most of them will take it as inspiration.

This is not only in the creation of scientific works, but also in the creation of literary works.

Some writers, because of their inspiration, write about the fictional world, maybe it is also some kind of high-dimensional information projection, in the heavens and all worlds, there may really be a real world, echoing the fictional world in the work.

Although Cheng Li feels that this inspiration is some kind of high-dimensional information projection, it is quite reasonable.

But he didn't expect that he was in a state of epiphany, how could inspiration come out so continuously.

Cheng Li even had the urge to write a book directly, and many difficult problems that he couldn't understand before, all of them had a feeling of sudden realization at this moment.

Cheng Li didn't know that the source of these inspirations was the mysterious information that he continued to inject into his knowledge of the sea from the arithmetic tablet in the process of answering the questions on the previous 2,000 floors.

After Cheng Li successfully answered a question, these mysterious information quietly flowed into Cheng Li's sea of knowledge from nothingness, and in this way, they precipitated in Cheng Li's sea of knowledge, hidden in the deepest part of the sea of knowledge.

And after Cheng Li entered the state of epiphany, when Cheng Li's thinking began to think about those difficult problems, when he encountered some incomprehensible problems, the mysterious information that had been precipitated in the deepest part of Cheng Li's sea of knowledge would automatically float out and be sensed by Cheng Li's thinking.

In Cheng Li's opinion, every time at this time, a flash of inspiration would flash in his mind, and an inspiration would burst out like this, and then a difficult problem that he couldn't figure out would be solved all at once!

That's why Cheng Li closed his eyes after the epiphany ended, as if he was still enjoying the pleasure of the inspiration just now.

"Epiphany is such a good thing! If you can, please let me do it again!"
