In the treasury of the Central Empire, there is a person who is frantically searching at this moment, this person is none other than Lu Chenye, and there is still an excited expression on his face, but compared with when he first came in, it is obviously much worse. Pen, fun, and www.biquge.info

After all, people's emotions are limited, and if they see too many treasures, they will slowly become numb, although the medicinal materials in the back appear more precious, but Lu Chen is not so happy at first.

This feeling is like a beggar, walking into a place full of food, although at first it is all buns, vermicelli and the like, but he eats very happily, gobbling it up, for fear that others will rob him, but the more he goes to the back, although the food is more and more precious, but he eats less and less.

It's not that he doesn't want to eat, it's that his stomach capacity is limited, so when he gets to the back, he can only eat slowly, picking the best and most expensive ones to eat, and Lu Chen at this moment is this kind of mentality.

"Alright, that's pretty much it."

Lu Chen looked at those precious medicinal materials a little reluctantly, and licked his lips, these were things he didn't need for the time being, as a disciplined person, it was impossible for him to empty the treasure house of the Central Empire, so he could only grit his teeth and walk towards the innermost....

The more you go inside, the higher the temperature you feel inside, no wonder there are some medicinal herbs that are more adapted to the heat, and when you walk to a wall, you feel that you have come to an end, because there is a thick wall in front of you.

On the top of the wall, there was a night pearl, exuding a silvery-white light, very soft, Lu Chen approached, gently stroked the night pearl, and when he sighed at its magic, his hand gently turned the night pearl, according to what Long Tian told him, he first turned three times to the left.

Then I turned two times to the right, and finally turned another circle to the left, and then pressed again, and suddenly the underground treasure house began to vibrate, making a roaring sound, and soon the earth wall began to split, and after a while, a small door appeared, and in this small door, there was a stone step that extended downward, obviously this was the step leading to the Earth Fire Alchemy Room.

Lu Chen didn't hesitate, he stepped on the stone steps with one foot, and then slowly walked towards the front, of course, he didn't let his guard down, his divine sense quickly shrouded a radius of dozens of miles, as long as there was a slight change anywhere, he could feel it, and he was also afraid of Long Tiankeng.

After all, as a smart person, it is impossible to trust a person absolutely, let alone leave his fate in the hands of a person he has just met, which is an unwise act.

The steps continued to stretch down, and with Lu Chen's divine sense, he could clearly feel the fire elements distributed around him, which were very rich, and the more he went to the back, the denser the fire elements became.

This place must also be an excellent place for fire system power and water transportation cultivation, but because it has been buried deep underground for a long time, no one knows about it at all, and the ruler of the Central Empire will definitely not bring people here to cultivate, what if one day, which person who is not strict in his mouth leaks the location of this treasure house?

People have a greedy side, and when the wealth in this treasure trove has exceeded the limit of his heart, all loyalty, morality, and the like are simply a fart in their eyes.

Therefore, the alchemy room of this underground palace, or the cultivation room, is only qualified to be used by the royal heir of the Central Empire, or the old ancestor, but in the Central Empire, there are relatively few people who cultivate the fire element, so few people from the Long family will use an underground cultivation room.

"Sure enough......

Finally, when I walked to the innermost, the fire element here was already very viscous, and it began to have a tendency to atomize, in this city, there was a huge Dan furnace, and this Dan furnace was the unique alchemy furnace of this continent.

If it was before, Lu Chen would not have been able to operate this alchemy furnace without the support of internal force, after all, the quenching of each medicinal material needs to be observed with his own strong spiritual power, and the separation of the medicine in time will be carried out, and the liquid medicine will be separated, and the rest will be burned into slag.

And those medicinal liquids that are useful, he must also be fused according to various orders, and the fusion is very critical and one is not good, which may lead to the loss of previous efforts.

Lu Chen also has some understanding of the alchemy furnace on this continent, in the past, he relied on countless precision operations, and the temperature of each outlet was adjusted, and only one kind of medicinal material was put in, so that he could melt quickly, and then use the switch, and the melted medicinal liquid flowed into a larger space for fusion.

And now, he has to throw all the medicinal materials into the Dan furnace blindly, and use his mental power to control the separation of these medicines from the residue, the more medicines he throws in, the more medicines need to be controlled, not only to control them from being burned, but also to control them to separate, and not to fuse them casually, but to fuse them in an orderly manner.

Therefore, Lu Chen only knows the theory, and has no experience in controlling this kind of Dan furnace, but Lu Chen is not discouraged, he says that failure is the mother of success, and he believes that practice is the only criterion for theory.

So Lu Chen started his alchemy life here, countless ordinary medicinal materials were thrown into the Danding by him, and at first he threw them one by one, slowly trying to separate them with spiritual power, extracting the useful medicinal liquid, and slowly, the speed of his separation became faster and faster.

Of course, the process of fusion is more difficult, at the beginning, due to the lack of understanding of the medicinal properties during fusion, there will be problems in terms of quantity, as long as it is a little more or less, when it is fused, it will not be able to achieve just the right balance, there will be an explosion, and then the previous efforts will be lost.

Although such a small explosion would not cause any harm to Lu Chen at all, it would also make him disgraced after a few days, but he was not a person who gave up easily, the more difficult he was, the more he had to swim against the current, so he could be regarded as competing with this alchemy furnace.

"Bang..."

"it, TMD failed again."

On this day, the alchemy room where Lu Chen was was made another loud noise, and the result was that Lu Chen had turned into Bao Gong's face, and he had already put all his spiritual power on controlling the medicinal liquid, so he was defenseless.

Although with his current physical strength, such an explosion could not cause him harm, at least there was no problem in dressing him up as a 'bag of sunspots'.

"It seems that it's still too hasty, you have to take it slowly, starting with the most basic pills."

After countless failures, Lu Chen finally summed up an experience, he had no problem refining at the beginning, and there was no problem in fusion, but when he was Cheng Dan, when he was fusing the total fusion, he felt a little awkward, which was the real reason for the failure.

As an alchemy master, Lu Chen was also confused by his identity at the beginning, he used to even be able to refine the divine pill, that kind of low-level elixir, do you still need him to refine it? ?

So at the beginning, Lu Chen was far less cautious than his own liquid extraction in terms of alchemy, after all, he had never done it before to control the separation of liquid medicine with his mind, so he was very modest, so in this aspect, he did a good job, but when refining the pill, what he chose was a high-grade elixir, which seemed very reasonable for Lu Chen's current identity.

However, he ignored an important problem, that is, he had never used this method to refine Dan before, so it would lead to repeated failures, and after these countless failures, Lu Chen finally found the key to the problem.

Now that he has found the problem, then he has to solve the problem, so he began to blindly use the simplest medicine, and began to practice slowly, at this moment, he has placed his position very low, as if he had returned to the moment when he had just made alchemy, everything was slowly groping by himself, and everything was starting from scratch...

With the experience of alchemy, coupled with his mastery of medicinal properties, he is already perfect, and his alchemy success rate has been slowly improving, at least every furnace, he can have a finished pill baked, instead of every time there will be an explosion like at the beginning.

"I can finally try the advanced elixir..."

For a serious person, time flies quite quickly, and here, Lu Chen seems to have forgotten time, forgotten the years, and is all focused on alchemy.

The success rate of his alchemy has increased from one percent to one hundred, of course, this is only based on the primary and intermediate pills.

Lu Chen was like building a house, starting from laying the foundation, and then building bricks layer by layer, and before he knew it, a skyscraper had revealed its rudimentary form.

"Saint-grade elixir, it seems that it can also be refined..."

At this moment, Lu Chen completely put his position right, starting from the most basic level of pill refining, step by step upward, and never thought of leapfrogging the level of alchemy, although he was already sure, but he always suppressed himself, reminding himself that he was just a novice.

Under such a powerful concept of self-hypnosis and superb technology, it would be too strange if it was not successful, and during this period of time, Lu Chen's alchemy speed and success rate were rising as fast as you are a rocket.

During this time, Lu Chen was completely immersed in alchemy, he didn't know how many pills he had refined, anyway, he had refined every grade of pills, and there was not only one furnace.

In order to achieve a 100 percent success rate, he carried out a large number of hand refining, and he refined countless furnaces for each level of elixir, and countless jade bottles were now densely piled up on the ground.

Fortunately, this room is large enough, and there are several rows of huge shelves on the wall, which are used to put pills, when Lu Chen came before, it was already covered with dust, but now, it has also been filled with all kinds of pills, they are all packed in jade bottles, and labels are attached to the outside, so that people can quickly identify them.

Lu Chen didn't seem to know at all how many pills he had refined, at this moment, he had already entered that crazy state, he was already fascinated, he didn't deliberately observe the amount of his alchemy at all.

Every time he ran out of medicinal materials, he would go to the outside medicinal herb room to get them, and then come back to alchemy, and then go back to get them, and so on...

And after refining the elixir, he would put it in a jade bottle, and then throw it on the ground, just like throwing garbage, at the beginning, he would also sort and classify him.

Later, he didn't have such patience at all, because he didn't use these at all, just used to practice his hands, so he just threw them there, and then left it alone, I don't know, if it is such a ruined behavior, when others see it, will it point at his nose and scold.......
