Iron Head, who had just been awake for less than half a minute, began to fight again with his eyelids, and the tiredness on his face could not be covered no matter what. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Looking at the exhausted iron head, Lu Yu felt warm in his heart and felt distressed at the same time.

"Iron Head, you've worked hard today. ”

"Well, it's fine. It's not hard, it's not hard at all. ”

At this time, the iron head was still strong. The iron-headed's straightforwardness made Lu Yu feel the urge to laugh.

The mouth said that it was not hard, but the two eyes of the iron head were almost closed, and even the voice of the voice changed a little, and the whole body began to shake.

Lu Yu, who was watching, was worried that the iron head would accidentally throw himself down.

"Well, it's getting late. You've been out for a day, and you probably haven't eaten. I still have a few leftover cold steamed buns here, you can eat two of them, and then go back to rest. ”

"Whew...... Ah, steamed buns, there are steamed buns, that's great. ”

As soon as Tietou, who was almost asleep again, heard that there was something to eat, his spirit was suddenly shocked, and he immediately staggered towards Lu Yu's house.

The dazed iron head even forgot to throw down the wooden stick in his hand.

Lu Yu, who couldn't cry or laugh, shook his head and followed in.

Outside, only a patch of silver moonlight remained.

Tonight, the moonlight was very cold, but Lu Yu felt very warm.

......

"Brother Lu, I forgot to ask you yesterday, how are you cultivating?"

"Well, it's a bit rewarding. ”

"Oh, what level are you at now?"

As soon as he heard that Lu Yu had gained something, Tietou immediately became excited, and hurriedly stepped forward and asked with a look of hope.

In that way, he seemed to be happier than he had made a breakthrough himself.

"There was a little problem, barely reluctantly, it can be regarded as a success in gathering spirits. ”

Lu Yu said this with a clear conscience, because yesterday's cultivation was indeed very thrilling, and he almost didn't scare himself to death.

"What, you've succeeded in gathering spirits!"

However, the reluctant result in Lu Yu's mouth directly shocked the iron head.

The iron head jumped up all of a sudden, looking at Lu Yu with a shocked face.

Tietou would not suspect that Lu Yu would lie, because Lu Yu didn't have to lie to him because of this. What was really shocking to Tietou was that Lu Yu had succeeded in gathering spirits so quickly.

It took more than a year to gather spirits successfully, and as far as the iron head knew, there were not a few in the entire Nine Xuan Palace.

What's more, Lu Yu was seriously injured before.

Tietou vaguely remembered that when he first saw Lu Yu in this small courtyard, Lu Yu was already dying, and most of his body was squeezed into the ghost gate. If he hadn't rescued himself, Lu Yu would have reported to the Hades Palace a long time ago.

But just over a year later, Lu Yu, who originally looked like he was suffering from five tuberculosis and seven injuries, not only recovered his body, but also succeeded in gathering his spirit.

After getting to know Lu Yu, Lu Yu's various behaviors were admired by Tietou, and Tietou always believed that Lu Yu was more capable than himself. But Tietou never thought that Lu Yu would be so capable.

The honest iron head, until now, I faintly felt what a terrible character he had saved because he was sympathetic in his heart at the beginning.

Of course, Lu Yu's breakthrough would not make Geng Zhi's iron head feel anything unhappy or jealous.

On the contrary, after the shock, Iron Head was more agitated than ever.

"Oh my God, Brother Lu, it's really good that you actually succeeded in gathering spirits. ”

The agitated iron head danced there, and from a distance it looked like a gorilla jumping up and down.

"Alright, don't be surprised, beware of spilling my medicine. ”

Lu Yu protected the medicine jar on the stove with one hand, and shouted at the iron head.

was said by Lu Yu, and the iron head was excited before he calmed down. Seeing Lu Yu carefully guarding the medicine jar, the iron head smiled at Lu Yu embarrassedly.

Lu Yu glared at Tie Tou, and then began to boil the medicine intently.

This pot of medicine on the stove was what Lu Yu had prepared for his next step of cultivation.

Refining medicine, Lu Yu actually doesn't know, it's just that as the young master of Ten Thousand Witch Valley, he has seen how the elders of the sect refine medicine.

At that time, the young Lu Yu also stepped forward curiously to ask a few words, so Lu Yu probably remembered a few steps of refining medicine.

If Lu Yu was still the young master of Wanwu Valley now, then he didn't have to refine the medicine himself at all, and naturally someone would send the best pill to him. And as soon as you give it away, it's a bunch, so that Lu Yu can eat it like a sugar pill.

If you really can't eat it, Lu Yu can also take it to feed a few of his pets.

It's a pity that the current Lu Yu can't enjoy that kind of treatment anymore. The dragon is trapped in shallow water, so he can only do it himself.

After the spirit gathering was completed, Lu Yu had to improve his cultivation as soon as possible and polish his Dan Yuan Cyclone to perfection. In this process, in addition to one's own penance, the best shortcut is to use some external objects.

And the elixir is one of the best of these foreign substances.

Although it can also improve people's cultivation, if you swallow it directly, it will inevitably be a little wasteful. If it is combined with some other materials and refined into an elixir, its effectiveness can be increased a lot in an instant.

Lu Yu, who used to eat pills as sugar pills, knew the benefits of pills deeply.

Therefore, after thinking about it for a long time, Lu Yu finally decided to do it himself and refine the elixir.

Although he was also a little apprehensive in his heart, Lu Yu thought that he could do it.

In Lu Yu's view, alchemy is nothing more than the alchemist throwing some medicinal materials with similar attributes into the medicine furnace, and then adding fire to the medicine furnace all the time, and when the time comes, the pill will naturally be good.

The process seems easy, but it shouldn't be difficult.

Otherwise, how to say that newborn calves are not afraid of tigers, if a person with a little experience knows Lu Yu's thoughts, he will definitely scold Lu Yu for being a madman.

Alchemy is far from as simple as it seems.

If nothing else, refining medicine must first understand the properties and effects of various herbs and materials, as well as how materials with different properties will react when they are put together.

It sounds simple, it's just a matter of memorizing something. But you must know that the land of Shenzhou is vast, and there are many creations between heaven and earth, and all kinds of rare and rare materials are emerging one after another, and people will discover new herbs and materials almost every year.

It takes a lot of time and effort just to research these new herbs.

As for those medicinal herbs and materials that have been studied clearly, after countless years of accumulation, there are at least hundreds of thousands.

Just knowing these known materials is enough for Lu Yu to spend a lifetime studying.

And understanding these medicinal materials is only the basis of alchemy. In addition, there is also the grasp of the heat, the combination of medicinal materials, the dosage of each medicinal material, and even the order of adding medicinal materials and the timing of the elixir.

All of these things can only be mastered through a long period of study.

Lu Yu only saw that his own alchemists were refining the medicine, it was very easy, but Lu Yu didn't know what kind of efforts those alchemists had made to achieve this step.

Moreover, Lu Yu is the young master of Wanwu Valley, how can it be so simple to be the person who was arranged to refine medicine for him.

You put a brand new elixir in front of them, and they only need to smell it once, and they can immediately tell the entire refining process of this elixir.

Almost every one of these people can refine the medicine of the Great Tonic into a poison that seals the throat with blood, and can also refine the medicinal materials containing the poison into a healing elixir that can be used to seal the throat.

This skill can not be mastered by Lu Yu by taking a look and asking a few words.

To put it mildly, in terms of alchemy, Lu Yu can't even compare to a single hair of them.

From this, it can be seen how blind Lu Yu was in deciding to refine the pill by himself.

But then again, if Lu Yu had the slightest way now, he wouldn't have taken the risk of taking this road.

Anyway, Lu Yu himself didn't know the consequences of blind alchemy, so Lu Yu regarded it as practicing for himself.

Regarding his alchemy, the ignorant Lu Yu didn't have much ideological pressure.

So early in the morning, Lu Yu called the iron head out and began to work on his first refining medicine.

To refine medicine, you first need medicinal materials. There are more high-grade medicinal materials, and Lu Yu doesn't have a single one in his hand. However, there are a lot of common medicinal materials in Lu Yu.

For most of the previous half a year, Lu Yu and Tietou had to go into the mountain three or four times a month. Since discovering that creek, Lu Yu and Tietou have sometimes spent the night directly in the woods.

Such hard work, in addition to allowing Lu Yu to hunt a lot of prey, also allowed Lu Yu to find a lot of medicinal materials in the mountains and forests.

There was even a time when Lu Yu was so lucky that he actually found a Ganoderma lucidum that was nearly 100 years old.

That night, Lu Yu didn't sleep all night with excitement. Holding the Ganoderma lucidum in his hand, he smirked all night.

It wasn't until after dawn that Lu Yu hid the lingzhi plant with great care. After that, he muttered a word.

"Damn, it's only this one. Did someone get ahead of them?"

Except for the Ganoderma lucidum, what Lu Yu found were some common medicinal herbs. Lu Yu adhered to the principle that if he didn't take it, it would be a waste, he scavenged all the medicinal materials he encountered.

Up to now, Lu Yu had accumulated thirty or forty medicinal herbs in his hands.

After the medicinal materials were available, Lu Yu did not immediately start refining the medicine.

Although Lu Yu didn't know the specific consequences of blindly refining medicine, he also knew that there was a certain risk in doing so. Therefore, for the sake of insurance, Lu Yu asked Tietou to take the opportunity of the sect's reward at the end of the assessment and asked the sect for a book on alchemy.

Lu Yu's statement for Tietou: Tietou has been sick since he was a child, and he has been taken care of by a barefoot doctor in the village, so Tietou has admired doctors since he was a child, and dreams of refining medicine to save people when he grows up.

The alchemist is also an excellent doctor in a sense, so Tietou's rhetoric did not arouse the suspicion of the sect.

Because Tietou's performance in the assessment was good, the sect also understood Tietou's little "dream". Gave Tie Tou a basic encyclopedia of medicinal materials.

In this book, thousands of common medicinal materials are collected, as well as their properties, effects, and taboos when used. It is not very precious, and it is an enlightenment book that every alchemist must read when they get started.

After getting the book, Lu Yu was ecstatic and spent eight days memorizing the entire book.

After making sure that he could skillfully tell the characteristics, attributes, effects, and taboos of each medicinal herb on hand, Lu Yu began to refine the medicine.
