Yuan Ming didn't rush back to Biluo Cave overnight, first, it was not safe to walk at night, and secondly, he didn't know where he was now, whether there would be any danger around, and he planned to wait until dawn.

He simply set up a grass hut in a wooded area by the lake, sat down cross-legged, and thought back to what had happened today.

Yuan Ming has a good habit, every time he encounters a major event, he will think carefully afterwards and summarize his shortcomings.

The reason why he was in danger again today was that he was not thoughtful and unprepared, knowing that the surface of Qianlu Lake was active and wide, but he did not think about the possibility of getting lost, there are also compasses and other things in Biluo Cave, if he prepared one in advance, where would there be trouble in the future.

Yuan Ming exhaled lightly and secretly kept this lesson in his heart.

Although he was in danger today, the harvest was also great, a set of "Strange Stone Records" classics, four pieces of fire chalcedony, a dark red hammer, a storage bag with a large space, and the black wood codex, each of which was a treasure.

"By the way, I almost forgot about this." Yuan Ming turned over his hand and took out an object, which was the red peach he had picked.

The peach exudes a refreshing fragrance, and you can feel the rich spiritual power contained in it, which is definitely a rare spiritual fruit, which may be of great help to cultivation.

It's just that he doesn't know the origin and effect of this fruit, so he rashly eats it raw, for fear that something will be wrong.

"Let's wait until we return to the sect and investigate clearly." Yuan Ming swallowed his saliva and put the immortal peach away again.

He took out the blackwood codex and flipped through it.

At the front of the codex is Master Kuroki's self-report, introducing his life, he was born in a small tribe of wrought iron in southern Xinjiang, and has had a great interest in refining weapons since he was a child, but unfortunately he was congenitally deficient in his body and could not learn the forging art of his own clan.

Later, by chance, Heimu was found to have a spiritual root, and it was a dual spiritual root of fire and wood, so he was sent to Biluo Cave to cultivate by the clan.

Heimu is not very interested in cultivating immortals itself, and his mind is still the art of alchemy, but the alchemy technique of Biluo Cave also has quite high requirements for physical strength, and Heimu is congenitally insufficient, and he still can't learn, so he can only do some sieving materials in the fire workshop, and the forging task with a small number of hammer swings.

Kuroki didn't give up, trying to do his part while looking for a solution to his lack of strength.

He firmly believes that he is a man who was born to refine weapons.

During this time, Master Kuroki came into contact with the art of exorcism and was immediately inspired.

With his own ingenuity, Master Kuroki forcibly combined the exorcism and refining hammer forging together, perfectly solved the problem of lack of strength, and officially embarked on the road of refining, and since then it has been out of control.

As Master Kuroki himself firmly believed, he was indeed a natural refiner, and it only took ten years to learn all the refining methods of Biluo Cave, and fused them with each other to create his own unique refining school, Kuroki Flow.

According to his own account, the back of the codex records all of Master Kuroki's lifelong refining experience, as well as his various ideas, which can be said to be the result of his life's pursuit and painstaking efforts.

When Yuan Ming saw this, his face became solemn.

Chen Wan said that although Master Kuroki was known as the No. 1 refining genius in Biluo Cave in a hundred years, for some reason his alchemy technique did not seem to have been inherited in Biluo Cave, and if the rest of the sect knew that the Blackwood Codex was in his hands, I don't know how much trouble it would cause.

"The matter of the foggy island, you can't let anyone know, that black storage bag needs to be hidden too!" Yuan Ming secretly decided, so he continued to watch.

The handwriting in the back began to be scribbled, basically the difficulties encountered by Master Kuroki when refining the weapon, or the complaints written in a bad mood, scattered and incoherent.

Yuan Ming did not slack off, read these words carefully, and did not let go of any subtleties.

According to Chen Wan, the sudden disappearance of Master Kuroki caused quite a stir in the sect, and some clues may be found from this codex.

These scattered words of Master Kuroki revealed a lot of information, after his alchemy technique became more and more sophisticated, it seemed that he was restrained by the Biluo Cave sect, and then he made a mistake in refining a special secret treasure, and finally resolutely decided to leave Biluo Cave.

"If this continues, everyone will die!"

This is the last sentence written by Master Kuroki in the Codex's autobiography.

"Everybody is going to die? What do you mean? Yuan Ming muttered to himself, unable to guess what Master Heimu meant by this.

Since he couldn't figure it out, he didn't bother in vain, looking through the Black Wood Flow Alchemy Technique in the back.

The handwriting here is very good, and it is clear that Master Kuroki writes every word with great seriousness.

The Blackwood Flow Alchemy is a four-step process, with the first step being to smelt the ore and then the forging of the embryo.

These two steps are no stranger to Yuan Ming.

According to Master Kuroki, smelting and forging embryos seem simple, but they are the foundation of forging a piece of artifact, and there are many places that need to be paid attention to, such as the ratio of ores, the control of fire, the strength of hammering, etc., any slight problem will affect the subsequent refining.

Master Kuroki has put a lot of thought into smelting and forging embryos, and the content of each step is much more complicated than in the fire workshop, taking the forging embryo as an example, there are at most 1,000 forgings in the fire workshop, but Master Kuroki here requires 10,000 forgings, and the details of each forging are also very high.

Yuan Ming took a cursory look, although there were many things he didn't understand, but sometimes he felt like waking up from a dream.

However, he didn't delve into it and continued to read it later.

Due to his lack of strength now, he can only get in touch with the first two steps in the fire workshop of Biluo Cave, and he doesn't know what the follow-up refining weapon is, he has long been curious, and now he can finally have a more comprehensive understanding.

Yuan Ming quickly turned the page, browsed ten lines at a glance, combined with his own scrutiny, and quickly figured out all the steps of refining.

After smelting and forging embryos, the next two steps of the refining vessel are engraving and instilling.

Only smelting and forging embryos are carried out, and the weapons created are just mortal weapons, and no matter how well this kind of weapon is forged, it is at most tougher and sharper than ordinary weapons, such as the herring sword.

In order to refine a magic weapon with special powers, it is necessary to engrave and infuse spirits.

The so-called engraved talisman is to engrave some runes containing magical power on the weapon, so that the weapon contains special effects, some can make the weapon sharper, some make it extremely strong, and even make the weapon inspire fire, thunder and other powers.

"The pattern engraved on the gravel hammer in the fire workshop is thought to be a rune, no wonder it can easily crush hard ore." Yuan Ming recalled the situation when he first sieved the material.

Runes are extremely precious, and every refiner is spending their entire life collecting as many new runes as possible, and every time they master a rune, they can refine a new magic weapon.

Master Kuroki is the same, his refining codex records forty-five kinds of runes, including "Sharp Runes", "Armor-Piercing Runes", "Wind Runes" and so on.

At the end of the page where the runes were written, there were some more complicated things, and it seemed that many runes were strung together, and with his current knowledge, he couldn't understand them at all.

It is not easy to engrave runes, Kuroki believes that each rune represents a kind of rule for the operation of heaven and earth's spiritual power, and there can be no mistakes when depicting, otherwise the entire rune will have no effect, and if you want to skillfully depict runes, you need to practice for many years.

Many refiners have a very limited number of runes that they can master in their lifetimes, and the main reason why Master Kuroki is famous is that he is extremely accomplished in runes, and he has mastered all the forty-five runes in this codex.

To refine a magic weapon, it is not enough to engrave the runes, after the runes are burned, they cannot immediately have power, and they also need to be infused with spirits.

The so-called infusion of spirits, to put it simply, is to inject mana into the burning runes to stimulate their power.

This step is easy to say, but it is not easy to do, the requirements for mana mana manipulation are extremely high, and these newly burned runes on the magic weapon are actually very fragile, and the slightest excessive impact will cause the runes to collapse.

And the spirit has another purpose, to completely merge the runes and magic weapons.

Only after the newly burned runes and magic weapons are fused together can they be completely stabilized and withstand the fierce collision of the fighting methods in the future, and to achieve this goal, it is far from enough to rely on skillful mana mana mana, but also requires an innate spirituality, which can also be said to be talent.

In the several steps of refining magic weapons, the probability of failure of spirit filling is the highest, even if it is a senior refiner, the success rate is only two or three percent, according to the codex, even if it is a master of black wood, the success rate of spirit filling is less than half.

When Yuan Ming saw this, he couldn't help but sigh at the difficulty of refining.

He continued to flip back, and soon finished the entire codex, looking into the distance.

Yuan Ming is not very interested in the way of refining, these days insisted on going to the fire workshop to learn forging, mainly to gain a firm foothold in Biluo Cave, and now that he has obtained this black wood codex, he has a shortcut in refining, maybe he can try to take a walk.

He didn't expect to reach the height of Master Kuroki, as long as he could refine the most ordinary magic weapons.

After staying in the sect these days, Yuan Ming became more and more aware of the power and importance of magic weapons.

The magic weapon is divided into four levels: lower grade, middle grade, upper grade, and best grade, most of the disciples in Biluo Cave are the lowest grade magic weapons, but they are low-grade magic weapons, and they are not capable of one person, as for the middle grade magic weapons, they are extremely rare, and only individual inner disciples have one.

Yuan Ming unconsciously thought of the figure of Kun Tu, the big black flag in this person's hand was called the Yin Ghost Flag, which was a medium-grade magic weapon, famous in Biluo Cave.

He had personally experienced the power of the Yin Ghost Banner, and if he hadn't escaped quickly, he would have died under this banner long ago.

As for the top-grade magic weapons and the best magic weapons, Yuan Ming has never heard of anyone owning them, and it is rumored that only the foundation building period exists, and there are such treasures in his hands.

He flipped his hand and took down his herring sword, in recent battles, this sword has played a smaller and smaller role, if it can be promoted to a magic weapon, even if it is a low-grade magic weapon, his strength can immediately increase greatly.

Yuan Ming was silent for a moment, then opened the black wood codex again, and looked at it from the beginning.

The night passed quickly.

Yuan Ming left the grass hut, and after determining his location, he went straight to the direction of the mountain gate of Biluo Cave.
