It has been half a month since the last time Du Rong practiced a furnace of blood pills alone, and since then, Feng Zizhen has personally come over to see the alchemy situation twice.

With this old man present, coupled with the fact that he had only been learning alchemy for a long time, it was impossible for him to increase his alchemy success rate to 100% in front of him.

Every three furnaces of elixir refining will basically be abolished, and this is not that he deliberately destroyed these materials in the production, but that he did not use the observation and control of spiritual power, and the success rate of refining these pills is so low and scary.

Until now, Du Rong has a clear concept, how difficult is alchemy, why Feng Zizhen is often proud of being a sought-after Dan master, and the difficulties in this are the deepest only when he has experienced it.

There is a specialization in the art industry, and although the divine sense of the monk who majored in the dantian is also useful, there is really a big gap compared with the spiritual power of the magician who focuses on cultivating the brain.

The Furnace Waste Pill was made purely by relying on his experience of flames, and at the same time, he also wanted to make progress in his true alchemy ability.

Using spiritual power is equivalent to opening up, and he himself hopes to rely on his own ability to truly refine a good elixir, if this process becomes too simple and natural, it will really damage the alchemy experience.

So Feng Zizhen, who came to watch, also felt a little strange, the kid in front of him practiced the pill smoothly, completely like a veteran who has been in this way for many years, and sometimes in some not too difficult fire control process, from time to time there are some inexplicable and wonderful mistakes that cause the furnace of pills to blow up.

Fortunately, there are not many strange states, and most of them happen on the last furnace of the day, and Toyoko really thought that he was overworked and unstable, and then he didn't pay much attention to it.

For the success rate of nearly seventy percent, Feng Zizhen is obviously very satisfied, since it has been melted, the cost of this pill has dropped to more than a hundred spirit stones.

Even if there is a loss of thirty percent, it is really not worth mentioning the price of thousands of lower grade spirit stones on the market for each Blood Pill. After coming and watching it twice, Toyoko really didn't show up again, and most of them didn't know what to make up.

Just before disappearing, he briefly instructed him about the matters that he needed to pay attention to in the Alchemy Hall, such as where the sect monthly pill to be distributed to the outer disciples if he hadn't come out for a long time, how to take it, and so on.

All that was left for Du Rong was the white jade porcelain bottle filled with the elixir he had seen before, and a palm-sized deflated cloth bag.

"What do you mean by giving me such a small bag?" Feng Zizhen didn't say anything when he gave him something, and Du Rong, who returned to the room, looked at the unsightly cloth bag in his hand with some curiosity.

Subconsciously pulled the elastic rope of the mouth of the bag, stretched open the mouth of the bag but was surprised to find that the mouth of the mini bag was actually pitch black and could not see the inside.

A one-meter-square space appeared in his sense out of thin air, and the object in his hand turned out to be a storage bag, and when he saw the contents inside, he knew what was going on.

It stands to reason that if he calculates two lower-grade spirit stones for every withered grass milled, he should now be a super entrenchment qi refining stage beginner disciple with more than 3,000 lower grade spirit stones, and with his current financial resources, he can completely crush those ordinary cultivators who have been cultivating for more than ten or twenty years, and they are all about to catch up with high-level qi refining cultivators like Sima Jing.

At the bottom of the storage bag, there were just dozens of lower-grade spirit stones and a scribbled note, on which were written a few words: "This storage bag is for me to help you exchange, worth more than 2,000 lower-grade spirit stones, and the remaining spirit stones are all in the bag." ”

"This old man really likes to make his own decisions. Du Rong looked at the note in his hand and rubbed the cloth bag helplessly.

More than 2,000 shiny low-grade spirit stones have just turned into such an inconspicuous cloth pocket.

He didn't expect that a storage bag with such a small internal space could be so expensive, no wonder he saw that even a high-level Qi refining stage cultivator like Sima Jing didn't have a storage bag on him, and his cultivation alone had already cost a lot of money, and he didn't have spare money to buy this somewhat frivolous storage prop.

Of course, ordinary Qi Refining Cultivators didn't have anything of value on them, and most of the money they saved was spent on magic weapon props and elixirs to improve their cultivation. The most valuable thing on his body is nothing more than those one or two talismans, a few talismans and untouchable cultivation.

However, for Di Durong at this time, this thing is still somewhat useful, and when he gets a few thousand more spirit stones in the future, the storage place alone is enough for him to have a headache.

This storage bag was purely his own small vault, and it would not attract attention, so he also threw the eighty lower grade spirit stones that he had hidden under the bed into it.

As for the bottle of Spiritual Pill, he still chose to put it outside, because during the time that Feng Zizhen was closed, he did not take this pill to keep himself in the realm of the Qi Refining Period.

A few days ago, he tried to use the fire elemental light ball of the elemental wheel in Zhihai to communicate the earth fire in the alchemy room, but he didn't expect it to be done at one time, which greatly provided him with convenience, and also saved a lot of pill costs, and this matter could not be used by outsiders, so he was very unceremoniously "laughing" at the part of the pill that should be consumed conventionally.

Du Rong found that spiritual power and magic have something in common at some point, although they are very different in origin, but the feeling after transforming them into physical means to perform them out of the body is the same.

He had deliberately experimented on a small scale when no one was around, whether it was spiritual power or magic casting techniques, half of the energy residues after use would dissipate over time and transform into attributeless aura, and the other half would become the corresponding magic elements and return to nature.

This made him a little surprised, the energy converted between the aura and the magic element was actually a substance in a very short period of time, and there were some different meanings.

So it's no wonder why the magic martial arts he risked using to attract Sima Jing didn't arouse his suspicions.

At the same time, he also noticed that the divine consciousness of the monk was not so sensitive, at least he used the very vague divine consciousness of the Qi refining period to infer that the sensitivity of the divine consciousness of the monk in the foundation building period would not be strong, of course, he could not infer the divine consciousness of the monk in the Jindan period further up.

As long as this old man Feng didn't get the golden pill for a day, Du Rong would rest assured that he would lock the door of the alchemy room and use magic to make alchemy, of course, if Feng Zizhen was there, he would still have to take the elixir to pretend.

And a few days ago, his six elemental orbs had all reached a stage of saturation, and quietly broke through to the second stage of the apprentice mage, and this strength should correspond to the second layer of the qi refining period according to Du Rong's judgment.

Feeling that every element in the sea of consciousness was more than doubled in the amount of mana, he couldn't help but shake his head and lament his spiritual power cultivation, but now it was still in a state of zero.

You can't have both fish and bear's paws, and now that he wants to major in magic and take withered grass, it will inevitably hinder the cultivation of spiritual power.

And when he reached the first level of the Qi refining stage, he felt that his Dao cultivation was like a mountain and a sea, and he couldn't see the clue of progress at all, and it couldn't be reversed without the work of the medicine stone.

Compared to his own smooth path of magic, he naturally focused his major energy on the latter first, and then slowly thought about this spiritual power cultivation in the future, so that the strong and weak sides could make both sides grow quickly and not hinder each other.

Therefore, as an unqualified monk, after Du Rong took over the handling of the withered grass again, he turned back into an ordinary person who had no spiritual power at all.

However, although his spiritual power subsided, his weak divine sense was still retained, floating quietly in the vast sea of consciousness, but he could not use it without the activation of spiritual power.

And under the condition of further magic, they all combine the experience and knowledge inherited by the characters in their previous lives, and they also develop a lot of new magic skills.

At this moment, he was facing a huge clay jar full of dead grass, and he had taken advantage of the gap to get medicine these days, and he didn't know where to find a dusty clay pot from the warehouse of the Medicine Training Hall, and after a little cleaning, he used it to grind the dry grass directly.

Since Feng Zizhen was still in his room and didn't come out, Du Rong had already thrown the very slow bucket aside.

Du Rong spread out his palms at this moment, his palms facing the mouth of the tank, and the tank was full of more than 100 fresh dead grasses. I saw him spit out softly: "[Spiral Wind Blade]!".

I saw that there was suddenly no wind in the tank, forming a strong air flow, blowing up the materials stacked in the tank.

And these air currents all extend in a vertical position with many horizontal wind knives, cutting wildly at the rolled up pile of dead grass. Suddenly, the broken leaves in the tank were sprinkled, and the juice flew sideways, but under Du Rong's palm, there was a wind net that densely covered the mouth of the cylinder, no matter how big the movement inside, all the broken juice leaves were pressed down by the wind net as a cover, without the slightest waste.

Except for the faint sound of broken dead grass residue hitting the cylinder wall, the whole process is unusually quiet, and this efficiency is a hundred times faster than before.

Looking at the movement under his hands, Du Rong also smiled happily, but he didn't expect that the magic effect developed with reference to the mechanical equipment he saw in his previous life was extremely significant.

Except for him, even the few people in this world who have the Wind Alien Spirit Root can't play like this, because he is a person who comes with a full set of theoretical systems and skills, and he can easily modify and process skills. If the Wind Alien Spirit Root wants to do this, it must have a relevant exercise, but there is a high probability that this exercise is not available.

With the blessing of this hanging magic, a whole vat of withered grass was processed in half a column of incense, and this grinding was so subtle that it only used a large cloth bag to strain the grass slurry and remove all the waste residue.

Looking at a vat of turquoise and slightly swaying delicate slurry, removing the layer of wind blocking sealed on the top of the jar, the heavy smell seemed to have finally found a pouring mouth and couldn't wait to squeeze it out, and Du Rong took a deep breath of the grass and sweet fragrance that could make the magic wheel ready to move, but it was highly poisonous to ordinary monks, and he couldn't help but feel happy.

However, this efficiency has been inexplicably improved by hundreds of times, but there is also a problem in front of him.

He saw that the clay pots that had been filled with dead grass but were now all empty after being moved to his room had been moved to his room, and that there were few jars left in the warehouse now.

Originally, Fengzi really prepared enough goods for him to consume for more than half a year, and he has been closed for a month, and it is estimated that he did not expect that this new little monster would completely ignore the progress of his own cultivation, and indulge in grinding medicine, the speed of this elimination is really terrifying.

"Shouldn't you interrupt this old man Feng to say that the medicinal herbs are almost at the bottom?"

Du Rong muttered to himself, he was a little hesitant at the moment, this work of grinding medicine can not only greatly increase his financial resources, but also a shortcut to his magic cultivation to improve rapidly, if there is no dry grass, for him, the progress of financial growth and magic cultivation will be left behind.

Just as he hesitated, a bell rang outside the door, and he quickly stood up and unlatched his door and opened it.
