In the eye, there are two things.

One of them, Qin Lang discovered, was an ancient book bound in thread.

Nowadays, all of them are printed books, and ordinary people can't find a thread-bound ancient book, so seeing such a thread-bound book, and the cover is quite old, Qin Lang thought at first that he had obtained some cheats.

Qin Lang thought secretly, as long as it wasn't a self-palace cheat like a sunflower treasure book.

But after opening the thread-bound book with no font on the cover and looking at it, Qin Lang immediately threw it aside like waste paper.

This thin thread-bound book is not a waste paper.

On the contrary, it is really cheats.

It's just that it's a secret book that records the vicious method of yin and yang dual cultivation.

Qin Lang knew why Sun Er had a look of pride on his face when he returned from exploring the treasure in the tomb.

Sun Er's Five Evil Sect is doing indiscriminate deeds, and such a vicious cultivation method is exactly what Sun Er wants.

Yin and Yang dual cultivation, it is not to find a martial artist of the opposite sex and cultivate according to the secret method recorded in the secret book, you can improve the strength of the two.

The reason why the double cultivation introduced in this secret book is very vicious is because its real meaning is to treat the other person in the double cultivation as a furnace.

Moreover, it is still a living furnace!

Qin Lang didn't look at the specific details, but he also figured out the general situation.

If he came to cultivate this secret book, then he would have to find ten virgins every month and forcibly suck the woman's Yuan Yin dry, although the woman would enjoy the joy of the bed, but the final price would be to become a dead person.

If you do the math, you can find ten virgins a month, and even if you only cultivate for three years, you need as many as nearly four hundred women!

What's more, these women will all die tragically in the end!

With such a vicious secret technique, of course Qin Lang would not cultivate.

He couldn't do such a hurtful thing.

Qin Lang didn't care about the other thing in the cloth bag, he picked up the thread-bound book first, walked to the bathroom, completely shredded the pages, threw it into the flushing toilet and flushed it away.

He resolutely would not use such a harmful cheat, and he didn't want this kind of harmful thing to wander outside and be cultivated by people with ulterior motives.

Washed away, this vicious double cultivation cheatbook will be as if it never appeared.

Qin Lang was a little happy afterwards.

Fortunately, the appearance of the ice phoenix killed Sun Er, otherwise let Sun Er leave Shaohu Mountain alive, Sun Er will definitely cultivate this evil secret book in luxury after returning to the Five Evil Sects, and when Sun Er's strength will increase greatly, he will have one more strong opponent, not to mention, there will be many innocent girls who will suffer a big disaster.

After returning to the living room, Qin Lang took out another thing in the cloth bag.

Although he had taken a general look at it before and recognized that this thing was like a furnace ding, after actually putting it in his hand to observe, Qin Lang still couldn't help but get excited.

He watched it again, and his mood was even more excited.

"This, it's actually a Dan furnace?"

Qin Lang was pleasantly surprised!

He inherited the memory of "Xuan Qingzi", and from the memory of "Xuan Qingzi", the alchemy master, he naturally had countless experiences in identifying the good and bad of the Dan furnace.

These experiences do not belong to him, but he can make them useful even if he is rigid.

After reading it twice in a row just now, he judged that the small purple furnace in front of him was most likely the Dan furnace used by cultivators based on these experiences in identifying Dan furnaces!

Dan furnace is a special instrument used for refining pills, in the Qinghe Continent, Dan furnace is large and small, the big one is very large, enough to accommodate an adult, and the small one is only the size of a palm.

But no matter how big or small, their use is the same, they all use the earth fire or the cultivator's own Dan fire to refine various mixed elixirs into molded elixirs.

All kinds of pills, such as Pei Yuan Dan, Nine Reincarnation Life and Death Pill, Soul Rejuvenation Pill, etc., must be refined with a Dan furnace.

This is also one of the main reasons why Qin Lang did not have alchemy before.

You must know that the cultivation of the earth has long been extinct, Qin Lang has no place to find a Dan furnace, the surface of the Dan furnace is carved with law patterns, these law patterns may be "Xuanqingzi" can be drawn, but he can't just have the memory of "Xuanqingzi", so he can't make a qualified Dan furnace.

And the rest of the planet?

They weren't even cultivators, they hadn't been exposed to cultivators at all, so naturally it was even more impossible for them to draw those Dharma patterns.

Therefore, although Qin Lang wanted to prepare for refining the pill in the future and wanted to have a Dan furnace in advance, he could only give up because he couldn't find it.

After confirming that the purple Xiaoding in front of him was the Dan furnace, Qin Lang couldn't wait to identify its grade.

Just as elixirs and elixirs are divided into lower, middle, high, and best grades, the Dan furnace is also graded according to this.

As long as Qin Lang gets a lower grade Dan furnace, he will be very satisfied.

After all, he had to practice Qi at the seventh level before he could officially refine the Dan, which was equivalent to a beginner's learning, and in the entire Qi training stage, a lower grade Dan furnace was enough for him to use.

Of course, if the grade is higher, Qin Lang will naturally ask for it even more.

The higher the grade of the Dan furnace, the better the quality of the same pill refined.

A few minutes later, Qin Lang looked happy again.

The purple Dan furnace identified is actually a medium-grade Dan furnace!

"Purple Cloud Furnace!"

Qin Lang then recognized the name of this Dan furnace from the words on the surface of the Dan furnace.

Maybe the lower grade Dan furnace only has a name in a general sense, but the middle grade Dan furnace is in the Qinghe Continent, and it is also a valuable thing that a qi cultivator's life savings can't buy, even if it is an alchemist in the foundation building period, it is also a lucky thing to be able to have a middle grade Dan furnace in his life.

Therefore, it is conceivable that the scarcity and preciousness of the Zhongpindan furnace are conceivable.

Therefore, every medium-grade Dan furnace will have its own name, and the owner of the Dan furnace is reluctant to just call it "Dan furnace".

And the Dan furnace in front of him is called the Purple Cloud Furnace.

The Purple Cloud Furnace is not big, about the size of an ordinary teacup, the whole body is purple, according to Qin Lang's estimate, using the Purple Cloud Furnace to refine the pill, the number of pills that can be produced at a time is about six to ten.

Of course, this is the number of good pills and waste pills.

In fact, when an alchemist refines a furnace of pills, it is difficult for them to make all the pills good.

Generally speaking, an experienced alchemist can produce a pass rate of 70% for the elixir, which is considered very good.

Qin Lang carefully put away the Purple Cloud Furnace.

He is only practicing the sixth layer of Qi now, and it is not the time for alchemy.

To refine the elixir, the four major conditions are indispensable.

First of all, it is natural to have a qualified Dan furnace.

Secondly, there must also be raw materials suitable for refining various elixirs, that is, elixirs.

Of course, on Earth, if you insist on refining some ordinary pills with the Purple Cloud Furnace, you can do it.

Third, it is the need for Danhuo.

Only when a cultivator has reached the Dan stage can he truly release the Dan fire.

This kind of Dan fire can be easily used to provide fire power for the Dan furnace, while a flame in the ordinary sense cannot stimulate the Dan furnace.

Above the Dan Period, there is also the Yuan Infant Period, and the infant fire of the Yuan Infant Old Monster is a more powerful flame than the Dan Fire of the Yudan monk.

In this way, it also means that the realm below the Dan period cannot provide Dan fire for the Dan furnace.

Below the Dan period, it is to build the foundation and practice qi.

There are several levels of cultivation, which are Qi training, foundation building, knotting, and Yuanying......

Qi cultivators don't need to think about it, even if they are like Qin Lang, who has a fire attribute spiritual root, they can release the fireball technique, but the flame of the fireball technique still can't move the magic pattern on the Dan furnace, that is, they can't heat the Dan furnace, and they can't naturally refine the pill.

At this time, if a Qi cultivator wanted to refine the elixir, he needed to find the earth fire in the natural world.

Earth fire is not a place where substantial flames are generated underground, but a place where there is geothermal energy underground, and of course, the amount of this geothermal heat is also not small.

Only by relying on the earth fire can qi cultivators refine the elixir.

Originally, the Zhuji monk was also considered unable to refine the pill because he couldn't release the real Dan fire like the Jiedan monk, but the Zhuji monk could actually send out a fake Dan fire.

Fake Danhuo means that the Danhuo is one grade worse than the Danhuo issued by the monk Jiedan.

When the Tsukiji Monk becomes a Jie Dan Monk, the fake Danhuo will become the real Danhuo.

Therefore, in a sense, the fake Danhuo is actually just a grade worse than the real Danhuo, and it can barely be used to refine the Danhuo.

It's just that because the quality of the fake Dan Fire of the Zhuji Monk is really not very good, so the Zhuji Monk wants to refine the Dan, and generally speaking, he will also go to those good grade Earth Fire Veins and use the Earth Fire to refine the Dan.

There is no doubt that now Qin Lang, even if he has the Dan Furnace and the Fire Glass Spirit Grass, but Qin Lang is only in the Qi cultivation period, and he can't even send out the fake Dan Fire, if he wants to refine the Dan, finding a place of earth fire is a condition that must be met.

And the fourth requirement of alchemy is that the monk's own strength must be above the seventh level of Qi training!

After all, alchemy is not about adding elixir to the Dan furnace, putting the Dan furnace on the ground fire or putting it on the Dan fire, just do it, in the process of alchemy, the loss of mind, the collection of earth fire, and the checking of alchemy, etc., all need to consume true qi, and before the monk reaches the seventh layer of qi training, he really can't hold on to the moment when the pill is practiced.

Dan furnace, elixir, Dan fire (or earth fire), as well as the strength of the seventh layer or more of Qi training, and the four major conditions are the four necessary points for a monk to be able to refine the pill.

Four points are indispensable.

Qin Lang is missing two points now.

Although Qin Lang really wanted to use the Fire Glass Spirit Grass to refine the Pei Yuan Pill and improve his cultivation, even refining things like the Zhuyan Pill and the Dragon Spirit Tiger Fierce Pill, he couldn't do it for the time being.

Qin Lang really wanted to become an alchemist.

The kind of scene where an ordinary Zhuyan Pill can make thousands of women flock to it, thinking about it, he feels very comfortable.

Imagine that when he wants to give a Zhuyan Pill that can make people ten years younger, even if this woman is Lin Zhiling, Yang Mi, or Liu Shishi, the other party is only afraid that he will put forward conditions, even if he proposes the condition of accompanying the bed, the other party will not hesitate to agree, right?

What's more, in addition to Zhu Yan Dan, an alchemist, he can also refine more kinds of pills, and the kind of situation where a random pill can be credited to hundreds of thousands of millions, can happen in minutes.

"Hehe, I'm really looking forward to it. ”

Qin Lang thought about it, and there was a rippling smile on the corner of his mouth.

Now that he is already a monk of the sixth layer of qi training, and he has the purple cloud furnace and the fire glass spirit grass, he is only left to find the earth fire and become a monk of the seventh layer of qi training.

Looking for the matter of earth fire, Qin Lang decided to start doing it now.

After all, even on the earth, there were no other cultivators competing, and if you wanted to find a qualified earth fire, it was not like you could find it.

As for the matter of cultivation, now that he is already at the sixth level of Qi training, with his current cultivation speed, he should be able to break through and reach the seventh level of Qi cultivation within this year.

Qin Lang understands that this is the earth, and it is likely that he will be able to become a monk for the rest of his life, and it is already a very great achievement to break through the qi training period and become a foundation building monk, and if he can't do it, practicing qi is the highest achievement, don't even think about building a foundation, after all, this is the earth.

Therefore, penance is a must, but Qin Lang is not good at being ambitious, one step at a time, first reach the seventh level of qi training, and be able to refine the pill.

When you become an alchemist, it will not be too late to think about becoming a foundation building monk and becoming a knot monk.
