The strong must have self-knowledge, the strong must know themselves, and know how many catties and taels they have, only in this way can they go further.

Only some fools, only some second-hand goods, think that they are invincible in the world.

Although in the Mandate of Heaven, Chu Yun competed for the first place, but this does not mean that he is really invincible, in this world, there are many capable people, strong people, etc.

Legend has it that some powerful Mahayana monks were able to reach a hundred. And some monks who defy the heavens are even in the realm of the Mahayana period, killing immortals. And at this moment, Chu Yun is far from being able to do this, and the gap with those legendary cattle people is not half a star.

Only in terms of mana has he achieved the peak of the Mahayana period, in terms of calligraphy, he has condensed the purple calligraphy qi, and in terms of physical arts, he has reached the peak of the ninth turn and entered the peak of the fourth turn, or even the fifth turn. At that time, the three can be combined to compete with those legendary cattle people.

With a movement of his hand, the nameless ancient book appeared.

Looking at the nameless ancient book, Chu Yun had mixed feelings.

Among the nine companion spiritual treasures that were born, it seems that the nameless ancient book is the most chicken and the most incompetent, because it is too chicken and too incompetent, Chu Yun simply didn't bother to afford a name, and directly replaced it with an unknown ancient book.

However, in the competition for the Mandate of Heaven, a huge power broke out, a book of Tai F Mountain, a stroke of heaven and earth, and finally killed the clone of the immortal king, competing for the first place. If there were no nameless ancient books, Chu Yun would really be in suspense.

"Now you will call it the Book of Truth!"

Chu Yun looked at the nameless ancient book and gave the book a name, and immediately the cover flashed, and four words appeared, the Book of Truth.

"The road to the Tao is long and boundless, and there is no end. I don't know when I'll be invincible, when I'll be able to take a break. The Tao is endless, not seeking immortality, not seeking vertical and horizontal, only seeking to explore the mystery of truth!"

............

Gathering his thoughts, Chu Yun began to increase his mana. Raise the realm of cultivation.

The way of cultivating the truth, only by going hand in hand in all aspects, and only by developing in an all-round way, can we reduce the shortcomings, reduce the shortcomings, reduce the flaws, and go further. And at this moment, the mana is too poor, Chu Yun needs to improve his cultivation, at least to reach the peak of refining the void.

And at the moment. With a movement of his mind, Chu Yun opened up the broken little world.

It is the Beidou world.

In the distant era, the Beidou Sect was founded, and its power was huge, not inferior to the Ten Holy Lands at all.

At that time, the Beidou faction opened up a small world called the Beidou world.

Later. The Beidou faction was besieged by strong enemies, and most of the strong fell. The small world is broken and closed. Today's Beidou Realm is already a dilapidated small world, equivalent to a large cave mansion, in which there are a large number of elixirs, and the age is extremely high.

This dilapidated little world was when Chu Yun was practicing Qi Realm. Experienced. In that small world, Chu Yun got the substitute puppet, got three imperial order papers, experienced the five decays of heaven and man, and condensed the five swords of slashing immortals. and two women took over the cause and effect.

And in the end, Chu Yun got the town boundary stone tablet and refined that small world.

Refining that small world to one of Chu Yun's fingers is equivalent to a large storage space, equivalent to a large mobile medicine garden.

And at this moment, Chu Yun happened to refine some pills, anyway, he was not short of medicinal materials.

"Come out, Diding!"

In the alchemy room, Chu Yun grabbed it with his big hand, and Di Ding appeared.

Emperor Ding, one of the nine companion spiritual treasures of Chu Yun, has no other specialties, and its biggest feature is that it can refine pills and weapons, and it is the furnace of Dan and weapons.

At this time, Chu Yun needed to refine two kinds of pills, namely the Huayuan Pill and the Breaking Pill of Destruction. The Pill is used to improve cultivation, and taking a pill of Pill can increase the mana of 100 people, and the Pill of Destruction is mainly taken by monks during the Tribulation Period to increase the success rate of the Tribulation. These two kinds of pills are both hypothetical pills in terms of grade.

With Chu Yun's cultivation, it was enough to refine.

It's just that, after all, this is the first time to refine a void-grade pill, Chu Yun urged Emperor Yan, threw the medicinal materials into it one by one, and began to refine the pill.

Warming the Dan furnace, Chu Yun gradually found his senses, as if he had returned to the Douqi Continent, and returned to the moment of Emperor Tushegu.

One by one, the medicinal materials were thrown in, Chu Yun began to refine, the Emperor Ding rotated, trembling, with a wonderful rhythm, inducing the changes of heaven and earth, absorbing the aura of heaven and earth, and Emperor Yan burned, turning into twenty-two flames, and began to refine the medicinal materials, condensing the medicinal liquid.

It is worthy of being a companion spirit treasure, and it fits perfectly with itself, and the success rate of alchemy has increased by at least two layers.

Chu Yun sighed, openly refining the pill.

Soon the first furnace of pills succeeded, and when I opened the pill furnace, I saw a pill in it, and bursts of pill incense came out.

"Medium grade!"

The condensation of the medicinal power of the elixir is divided into four grades: inferior, medium, superior and perfect according to the absorption of medicinal power.

Inferior elixir has the lowest degree of cohesion, and perfect elixir has the highest degree of cohesion. The color level of the elixir also determines the difficulty of refining the elixir again.

Many pills, if they are not successfully refined, they will be taken, and there are very few days like this.

These pills that have just been successfully refined are called young pills. The Hina Pill is the primordial elixir, the most primitive stage of the elixir, which contains a large number of toxins, and poisoning monks often occurs.

Many pills are often refined again after successful refining to improve the level of pills, reduce erysipelas, and improve absorption efficiency. Therefore, there is a saying that the pill has nine turns, and after a turn, the erysipelas of the pill is reduced, and the absorption efficiency is improved again.

After nine turns, erysipelas disappeared completely, and the absorption efficiency was 100%.

However, the vast majority of pills are mostly one or two turns, only a few pills can be turned three times to six turns, and only a very small number of pills can be turned seven to nine turns. Among them, there is certainly the problem of the level of the alchemist, and there is also the problem of the grade of the young elixir.

The grade of the pill determines the number of times the pill can be refined again.

Only perfect-level young pills are qualified to go through nine refining times, go through nine transformations, and become the king of pills.

The grade is only medium, and I am not satisfied, but it can be refined three times to four turns, and the number of refining is too much, and it is very likely that it will be wasted.

Chu Yun began to refine the second furnace of pills again, which increased the difficulty of alchemy and began to increase the number of pills produced.

For alchemy, the minimum requirement is that the pill is successfully refined.

The high requirement is to improve the grade of the elixir, and the other high requirement is to increase the number of furnaces refined.

There is quantity, there is quality, without quantity, no matter how high the quality is, it is useless.

After all, the pill is a consumable consumed in large quantities.

After all, an alchemist will not stay in the alchemy room every day to refine pills, and he will die of boredom if he is bored. Many alchemists refine pills in order to earn various resources and improve their cultivation. In order to refine the elixir, the cultivation of comprehension is wasted, but the gains outweigh the losses.

An alchemist can only refine pills, his cultivation is low, he is just a fat sheep that has been slaughtered, and he is just the fate of a cow, and most of them have become Dannu and live a miserable life.

In order to save time, alchemists began to refine only one pill in one furnace, nine pills in one furnace, and dozens, hundreds, or even thousands of pills in one furnace. (To be continued......)
