Back on the mountain, the white-eyed wolf who hadn't seen Tang Long for a few days immediately ran over with excitement and circled around Tang Long, looking extremely happy.

"You guy......" Tang Long shook his head with a smile.

He knew that this guy was so happy, not only to welcome him home, but also to ask him for favors, completely a foodie dog!

However, Tang Long did not disappoint the white-eyed wolf, and after scolding with a smile, he still took out a piece of demon beast meat and threw it to it, and directly sent the white-eyed wolf away.

After sending away the white-eyed wolf, Tang Long returned to the small building, and it didn't take long for him to come out again.

And after coming out, Tang Long walked straight towards the mountain, and that direction was the direction of the alchemy room!

"There's still time, so I'll do that today!"

Thinking of this, Tang Long's steps became faster and faster.

It didn't take long for him to come to the door of the alchemy room, and with a glance in his eyes, he had already looked towards the alchemy room.

――――

Alchemy Room: Level 1

Durability: 10001000

Dan Furnace: Cheng Dan rate +5

Gain +10% for proficiency

――――

First of all, he called up the attribute bar of the alchemy room and looked at it, and when Tang Long saw this attribute bar, he couldn't help frowning.

"It's strange, I've been away from Kyoto for a few days, and the durability of the alchemy room hasn't dropped at all? Could it be that I was wrong at first? ”

Durability, this attribute bar had been discovered as early as the beginning of the construction of various special buildings, but he didn't pay much attention to it at the time, thinking that it was also the result of mutations in reality.

Originally, he thought that the durability of these buildings would decay over time, just like ordinary buildings in reality.

But seeing this scene now, Tang Long felt that his thoughts seemed to be a little wrong.

"Isn't it ......"

I don't know what came to mind, after a little hesitation. Tang Long's eyes lit up suddenly, "Most of the time, this durability is mostly consumed when I use the Dan Furnace for alchemy!" ”

The more I thought about it, the more it felt right, and in the end, Tang Long could even be sure of this!

It's a pity that he is not an alchemist yet, so he can only guess in his heart. But nothing can be confirmed.

But even so, this discovery still made Tang Long breathe a sigh of relief.

After all, if that's really the case. Then he will not have to pay attention to the durability of these special buildings from time to time.

Entering the alchemy room, he glanced left and right, it was no different from the last time he came, a few steps to the alchemy furnace, Tang Long directly called up the attribute panel of the alchemy furnace.

――――

【Dilapidated Copper Furnace】

Quality: 5

……

――――

The attribute is very simple, and it can even be said to be shabby, that quality 5 is the most important attribute that increases the success rate of alchemy by five percent, and the proficiency bonus is brought by the alchemy room itself.

However, Tang Long obviously didn't want to take a look at the quality of the copper furnace before opening the copper furnace attributes.

Sumeru, Tang Long's eyes suddenly lit up. He finally found what he needed.

"Sure enough, I have this ability!"

――――

Dan furnace comes with features:

[Decomposition]: Consume a certain amount of spirit stones, which can decompose unwanted pills and medicinal materials, and have a certain chance to produce special props.

Note: The highest item that can be produced by a level 1 Dan furnace decomposition item is 'Dan Pith'.

[Refining]: Consuming a certain amount of spirit stones, the alchemy materials can be purified once.

Note: Each raw material can be purified at most once, according to the grade of the Dan furnace, there is also a limit to the materials that can be refined, and the maximum grade of the 1st grade Dan furnace refining material is 2.

――――

The Class 1 Dan furnace has two additional features. And Tang Long came this time, it was for the [refinement] function of these two functions!

Decomposing this function is not used by Tang Long now, or he does not dare to use it at all, but now this Dan furnace can be used to refine this function.

What the?

Why didn't he dare to use this feature, you ask?

Well, each time you dismantle, you will always consume a 'Downgrade Spirit Stone of 'Dismantling Item Level 10'. With Tang Long's current net worth, how dare he use it?

His little spirit stone is probably not enough for him to squander it a few times!

Besides, even if he dared to use it, there was no pill or material for him to decompose it now!

Refining this feature is completely different!

This function, without a doubt, is exactly what Tang Long needs most today!

"I want to quickly improve the proficiency of the doctor's sub-profession. The only way is to brush it directly regardless of consumption! ”

"Most of the medicinal materials produced by the copy are useless, or even if they have a little effect, they can't be used to make useful potions, but these things are not useless."

Thinking secretly in his heart, Tang Long's consciousness was already immersed in the few Qiankun bags he brought.

Materials, all medicinal materials!

Moreover, these medicinal materials are all produced in copies, and they are full of three Qiankun bags!

How many are three Qiankun bags?

Obviously, as the person who dislikes to care about such boring things the most, Tang Long himself did not calculate carefully.

However, he knew that these medicinal materials.

Whether it's the corpse of the Second Realm Demon Beast Flower Demon, or some flowers and plants, or Teng Vines!

This qiē is already all the belongings he has been accumulating since he got the system!

That's right!

That's all!

Ever since the opening of a single dungeon, a place dedicated to farming low-level materials, Tang Long has used up his number of times almost every day.

It wasn't until a few days ago that he raised the dungeon to the hard level, and he had no choice but to stop.

And before that, all the medicinal materials he brushed were here at this time!

Thinking that he had to do his best to be promoted to an alchemist, Tang Long felt a little painful, you must know that this is all his belongings!

And even with so many medicinal materials, he still didn't have the absolute certainty that he could be promoted to an alchemist!

And once he didn't succeed, then this time his plan to quickly attack the alchemist would undoubtedly be considered a complete failure, after all, he didn't have more high-proficiency materials produced by the copy!

"Fight! Now if you want to reach the alchemist as soon as possible, there is only this one, even if it is wasted, you will not hesitate to do it! ”

Indeed, his time is really tight these days.

Not to mention the matter of the Three Sages, there is still a period of time.

Just after being promoted to an alchemist. He also has to refine Zhuji Dan, and then he has to break through the realm and become familiar with the realm......

This is already doomed that he must be promoted to the sub-professional level of alchemist!

And to meet his requirements in such a short period of time, Tang Long thought about it in his heart, and in the end he only found such a way.

In fact, his method is also very simple. It's just this simple, but it's very violent!

This method. It's just to pile up proficiency with materials!

……

Refining materials can improve the quality of materials by one level!

In other words, if the primary basic material is only a level 1 material that is recognized by the system.

Then, the refined material is a level 2 material!

What is the difference between Class 1 and Class 2 materials?

The difference is gone!

For example, the level 1 material is the corpse of the first-realm demon beast, and the second-level material is the corpse of the second-realm demon beast, these two. Can they be compared with each other?

And the most important thing is that the level 2 material, with Tang Long's current ability, except for the corpse of the flower demon, he can't get it at all!

As for the comparison of the roles of the two, the doctor's subclass uses level 1 materials to increase proficiency, which is originally considered a level-level promotion. And level 2 ......

"With second-level materials, the proficiency increase is ten times higher than the original!"

You heard it right, it's ten times over!

The same material, which has not been refined, is the proficiency obtained by both compared to the material after it has been refined. That's a tenfold difference!

Seeing that the same materials in front of him were taken out one by one, there were thousands of strange and varied patterns, and there were even some more precious medicinal materials, the corners of Tang Long's mouth couldn't help twitching.

Even at a certain moment, he almost couldn't resist giving up this method, but in the end. He finally held back!

"As the saying goes, if you can't let the child trap the wolf, I can be regarded as having gains and losses, right?"

Tang Long naturally understood this truth.

Even if he knew, once he had raised these materials to level 2.

He's still a doctor at the level of a sub-professional.

After using these materials, you will definitely get nothing but proficiency!

However, when he thought of the purpose of his promotion to an alchemist, he had to endure it!

Fortunately, refining and decomposing are different.

Although it also consumes spirit stones.

But one is to consume dozens or even hundreds of spirit stones at a time.

The other is just using spirit stones as the power source, so the consumption is not large.

Otherwise, if there were also massive requirements for spirit stones, Tang Long would really be helpless......

Refining the material is very simple, but it is also very boring.

Just put in the spirit stone, put in the materials, and then receive the refined materials.

Halfway through, Tang Long only needed to pay attention to the consumption of spirit stones, so that he could replenish this at any time.

In the blink of an eye, an hour passed, almost mechanically, at a rhythm of once every half a minute, Tang Long finally purified all the materials!

There is no way, although when refining, he can also directly put a type together to purify it once, but the types of low-grade medicinal materials are the most, and the types in his hand are still few, but there are more than a hundred!

Wait until the purification is complete, and now look at it.

Originally, all kinds of medicinal materials had already disappeared at this time.

And now all that is left is the essence of various medicinal materials of different colors, or muddy, or liquid, or solid!

It took some more time, and Tang Long simply sorted out the material essences that were a little messy, and then began to calculate.

"There are a total of one hundred and thirty-seven kinds of medicinal materials, the least of which is the one in number, and the number has reached thirty, and the most one is nearly a thousand!"

"However, although these seem to be a lot of them, the proficiency required for me to reach the alchemist is also quite a lot, and even these are not enough......

Call! ~

After careful calculation, Tang Long finally had a bottom in his heart, these materials didn't seem to be enough!

After all, it was a one-time promotion to an alchemist, and the sub-profession of doctor, in reality, was originally the most difficult to raise the level, and it was only now that Tang Long also promoted it to the intermediate level.

Intermediate!

There are also advanced, grandmaster, and grand grandmaster levels behind it!

Finally, when the Great Grandmaster level is reached, you can try to advance to the Alchemist!

Among them, that's a few big grades!

"But it's okay, I've been prepared for this!"

Although the materials were still a little insufficient, this was obviously difficult for Tang Long, who had already considered it, because when he calculated it just now, he calculated the result by ignoring the ten-percent proficiency bonus in the alchemy room!

Now, with the addition of the 10% bonus of the alchemy room, then the gap should not be big!

Of course, for the sake of insurance, Tang Long still planned to do what he thought at the beginning.

Thinking of this, Tang Long couldn't help but pull out his sect attributes, and muttered: "Although the materials required to upgrade the building level are very terrifying, but if you only upgrade one or two, and it is also from level 1 to level 2, I have accumulated enough here." ”

That's right, the safest way Tang Long thought of was to raise the building level!

Ten percent is not insured, but what about twenty percent?

Twenty percent, without a doubt, is definitely enough!

The main hall, level up, confirmed!

Because of the increase in the level of the main hall, the seal that restricts other special building levels has been lifted by level 1, and the original gray upgrade option of the alchemy furnace is directly shining!

Alchemy room, level up, OK!

Swish! ~

At the moment when Tang Long chose to be sure, he was suddenly forcibly teleported out of the alchemy room, not only him, but even his material essences were also teleported out!

And immediately after, the entire alchemy room began to undergo earth-shaking changes!

First of all, the foundation!

I saw that the entire foundation of the alchemy room suddenly began to widen automatically, and it was also automatically heightened, becoming more reliable at a speed visible to the naked eye!

In addition to this, the building of the alchemy room itself has also begun to change, in addition to its scope and size, it has become more luxurious and magnificent!

And, of course, most importantly, its properties are starting to change!

――――

Alchemy Room: Level 2

Durability: 20002000

Dan Furnace: Cheng Dan rate +10

Gain +20% proficiency

――――

Durability has risen by 1,000, and the Cheng Dan rate has also doubled from +5 to +10!

Of course, the most important thing is the last one!

Mastery gain increased from +10% to +20%!

"Now, there should be no problem, right?" Looking at the alchemy room that had changed drastically in front of him, Tang Long, who was still a little stunned, couldn't help muttering to himself.

Obviously, Tang Long was very satisfied with the changes in the alchemy room.

When the alchemy room was completely upgraded, he didn't hesitate, quickly cleaned up the mess on the ground, and entered the alchemy room again.

Just kidding, if the twenty percent proficiency bonus isn't enough, then he can really just give up!

Next, it's time to start working on a mastery frenzy! (To be continued...... ）
