After looking at it for a long time, Chu Mu put this Yidan pattern of Nourishing Pill back into the wooden box.

After taking a little spare time to easily refine the raw materials of Bigu Dan brought by Wang Mazi into Bigu Dan, Chu Mu sat down at the table.

A good memory is better than a bad pen.

This habit, from the previous life, extends to this life, and is still used to the current immortal journey.

The jade slips commonly used in the immortal cultivation world to record knowledge and information are precious, but for him today, they are not unaffordable.

But he is still more accustomed to writing with the tip of the pen, and every stroke falls, for him, it is also a kind of thinking, but also a kind of review and learning.

Under the habit of many years, although the words are not the words of the previous life, they also obviously carry the writing habits of the words of the previous life.

Holding the pen and dipping it in ink, stroke by stroke, all are like a knife and an axe, which is strong and sharp, but vaguely, there seems to be a sense of restraint.

The so-called words are like their people, and they also seem to correspond to Chu Mu's slightly contradictory character.

Between the strokes of the pen, lines of fonts appeared, and in my mind, the refining scene of Yangmai Dan also emerged again and again, and finally fell on the tip of the pen and appeared on the white paper.

Several hours passed, and finally, there was a thick stack of white paper, recording in detail the refining process of Yangmai Dan, as well as many experiences.

The blank paper was bound into a book and stacked on the desk.

When I got up and went to the door, it was already late at night, and the street was bright under the flickering lights.

Everywhere you look, the attic doors are closed, and in it, it is like a high-rise building in the community in the previous life.

It's obviously close at hand, but it's hard to communicate.

Taking out the transmission note, Chu Mu pondered for a moment, and finally took it into his arms.

With a calm expression, Chu Mu walked into the room, and the door was closed again.

In the past, the Yang Mai Pill worth fifteen spirit stones was also a heavy burden for him.

He can only buy a few grains every month, although there are only a few grains, but with the accumulation of time, coupled with the rich aura in this house, his cultivation has also entered an unprecedented fast lane.

In just half a year, he crossed over to the realm of the fourth layer of qi training.

And now, the number of Pulse Nourishing Pills he can use is as high as twenty-five, and there is also a One Dan Pattern Nourishing Pill!

Converted to the market price, even if you don't count the one Dan pattern Nourishing Pulse Pill, its value is as high as three hundred and sixty lower-grade spirit stones.

You must know that his half-year Spring and Autumn cultivation fast lane was only to buy thirty Pulse Cultivation Pills.

"Hopefully there are no bottlenecks."

When Ning Xin was calm, such a thought suddenly appeared in his mind.

There are many thresholds for immortals, and the lower the qualification, the more thresholds there are.

The crossing of each major realm is an indispensable threshold, and the crossing of each small realm will also have a chance to encounter a threshold bottleneck.

And this so-called probability, there is a law in the immortal cultivation world, the lower the qualification, the more thresholds, the higher the threshold, and the more difficult it is to cross.

The reason for this is that the lower the qualification, the more spiritual root attributes will be, and the cultivation of immortal cultivators is generally based on a single attribute.

And the mixed spiritual roots, even if they practice single-attribute exercises, will be imperceptibly affected by other attribute spiritual roots, so that the mana attributes are mixed.

Mana is the foundation of cultivation, and if mana is mixed, cultivation will naturally be difficult.

At the same time, taking pills for a long time to assist in cultivation is much greater than simply breathing in the spiritual energy of heaven and earth, and the probability of encountering bottlenecks is much greater.

The reason for this is that no matter how pure the medicinal power is, the nature is different from the aura of heaven and earth, and there will be some confusion that is difficult to detect and difficult to get rid of, which is commonly known as erysipelas.

The accumulation of miscellaneous accumulations over time will naturally have an impact on the cultivation realm, thus becoming the so-called bottleneck threshold.

There is no doubt that except for the threshold bottlenecks of each great realm, all the other threshold bottlenecks are derived from mana.

Chu Mu sensed the illusory long knife in his soul, felt the fluctuations in the underworld, and the worry in his heart slowly subsided.

In addition to Linghui, he may still be a little different from ordinary people.

The thought flashed away, and a pulse nourishing pill entered the throat.

The surging medicinal power, wrapped in mana, was rapidly refined, growing with the appearance of the illusory long knife, which had turned into a mist mana.

Today, his understanding of Qi cultivation has long been different from what it used to be.

The so-called thirteen layers of qi training, one step at a time, is actually a process of growing and condensing mana.

In other words, the thirteen layers of Qi cultivation are the process of improving the power and quality of the Fa.

And under the influence of the illusory long knife, although his cultivation was still low, the quality of his mana and divine soul had already taken a big step forward.

Although this also caused his cultivation speed to slow down a lot, compared to immortal cultivators in the same realm, his mana was naturally much stronger.

The mana and divine sense are strong, which undoubtedly means ...... Combat effectiveness, the improvement of survivability.

With the improvement of cultivation, this kind of vigor will inevitably become more and more obvious.

The closer it is to the power of self-preservation in Chu Mu's mind.

A Pulse Nourishing Pill has been refined in just half an hour.

The mana was still circulating, and Chu Mu did not stop cultivating, the divine sense and the illusory long knife in the divine soul were one, silently perceiving the mysterious fluctuations, perceiving the divine soul and mana that were tempered under the fluctuations.

The deeper his understanding of cultivation, the more careful and awe-inspiring Chu Mu became.

On the path of cultivation, the slightest slack may eventually turn into a chasm that is difficult to cross.

Nearly an hour passed, and Chu Mu slowly opened his eyes, and in his field of vision, the light curtain panel also appeared.

[Name: Chu Mu.] 】

[Skill: Basic Knife Technique (Peak) 6238/10000.

Fireball (Ascending to the Peak) 2896/10000.

Flame Barrier (Ascending to the Peak) 98/10000】

【Flame Break 4th Floor (300/2000)】

[Alchemy: Bigu Dan: Reaching the Peak (8953/10000)

Yangmai Dan: Entering the House (235/2000)】

[Radiance value: 2103.3%]

His gaze froze a little on the value of the Agni Duel, and the light curtain panel disappeared.

In the past two months, he has focused on the pondering experiment of the elixir of the Nourishing Pulse Pill, and the sword spell has also been put on hold, but in his spare time, the cultivation of the Agni Technique has not fallen too far.

Without the assistance of pills, although there is not much progress, there is some progress.

And this one is a nourishing pill......

Chu Mu frowned slightly, thinking slightly.

At the beginning, after taking the Nourishing Pulse Pill, almost every Nourishing Pill can improve the proficiency of about sixty in the Agni Duel.

After that, as the cultivation was improved, it gradually decreased slightly.

So far, the fourth layer of Qi training, the cultivation just now......

Around fifty o'clock!

Soon, Chu Mu determined the approximate value.

Cultivation is promoted, and the effect of the Yang Mai Pill has been weakened by about one-sixth.

Immediately, Chu Mu subconsciously looked at the Yang Mai Dan Pill.

Beyond the efficacy of the pill itself, he has a lot of experience above the Bigu Dan.

Since he began refining Bigu Dan, he has almost never had a desire to eat and appetite anymore, and it is basically a Bigu Dan with a Dan pattern to maintain his body.

And the Bigu Pill he refined, generally speaking, can only last for five days, and the Bigu Dan with one Dan pattern has also extended this maintenance time by nearly double.

It may be the reason for the special nature of Bigu Dan, but it is not difficult to see how special the pill with Dan pattern is.

"Boom!"

Just as he was thinking about it, with a roar, the house shook, and at this moment, the hidden formation prohibition suddenly appeared, and the dense array text had already wrapped the house in it.

The shadow of the beginning seems to have resurfaced.

Chu Mu got up violently, his whole body was tense, the mana flowed, and the slightest flame was already emerging from his fingertips.

Immediately, I saw a bloody flash outside the window, and a figure flew by.

Chu Mu's pupils shrank, and he slowly approached the window, and the street scene was clearly visible.

A bloody corpse had collapsed at the door of the attic opposite, and it seemed to be holding a talisman in its hand.

Looking in other directions, there were immortal cultivators watching from afar, but there was no other abnormal movement!

……

More eight thousand
