To be honest, this rune array made by Han Xiao is a set of "intelligent programs" arranged with runes, which is used to replace manual labor and monitor and adjust the process of alchemy.

Of course, the rune array is not omnipotent, it can only find problems but cannot deal with them, and there are some key problems that still need to be dealt with.

Therefore, even with this complete set of talisman arrays, if Han Xiao wants to completely get out of the alchemy process, he still needs to have talents in this area to take over his work.

Fully automatic alchemy, that is absolutely impossible, there must be professional people to monitor, adjust and deal with the errors in the alchemy process.

It's like pharmaceuticals can't be fully automated.

The more clever and important the pills, the more difficult it is to refine, and it is still difficult to refine many pills manually, let alone automated......

Even with the rune array, intelligence and standardization are already the limits of what Han Xiao can do at present. However, the simultaneous production of a hundred alchemy furnaces is not the limit of Han Xiao himself and his set of rune arrays.

According to Han Xiao's rune array's setting, his rune array could hold thousands of alchemy furnaces.

Therefore, Han Xiao still has to refine nine hundred alchemy furnaces, fortunately, he does not have high requirements for the materials of the alchemy furnaces, otherwise, if all of them have a magic weapon level, then the difficulty of refining is high, not to mention the difficulty of refining, the magic weapon materials alone are enough for Han Xiao to have a headache - he simply does not have so many magic weapon materials.

Besides, magic weapon materials are not like magic weapon materials, they are rare goods in the world of cultivating immortals, and they are generally priceless in various large and small markets, even if they are people with strong financial resources, they can't receive much.

It can be said that once the magic weapon material appears, it will be purchased by big forces and big conglomerates.

"Refining is actually a kind of enjoyment...... Watch as various materials are refined, melted, and shaped in your own hands...... It's a creation out of nothing, the same work that the creator God did......"

The special refining technique no longer relies on refining tools, so that the materials can be changed and formed under the precise refining of the five systems of water, fire, wind, thunder and earth, as if using magic......

No, now, the legendary magic on the earth is no longer in Han Xiao's eyes, because he really knows magic now, and it is the legendary immortal method...... Ah no, to be precise, it's an immortal spell.

Created out of thin air, that's God.

It is human beings who use matter to transform it into new substance.

What Han Xiao is doing now is not just a machine, these alchemy furnaces have also incorporated various means and elements of the immortal cultivation civilization, especially runes, so they are magic weapons.

Nine hundred magic alchemy furnaces were born one by one in Han Xiao's hands.

After that, they were placed into the runic array that Han Xiao had arranged earlier......

"Generally speaking, the symbol is loaded with the instrument, and the instrument is the soul ......"

Han Xiao felt that in fact, if it was possible, if a refining master wanted to be comprehensive, if he wanted to go further, he should learn and master the rune path...... And a rune master, if he wants runes and rune arrays to be more useful, then he should also learn and master refining weapons.

Because, if we use the way on earth, the meaning of the phrase "the talisman is the carrier, and the instrument is the soul of the talisman" is that the refining tool is the hardware that carries the rune, and the rune is the soul that runs the magic weapon and the magic weapon.

Of course, this is a common statement, not an absolute one.

In fact, runes, such as Han Xiao's qi talismans, are based on the body, and they can also run without hindrance.

"Medicinal herbs, put into ......"

"Energy, Turn on ......"

"Alchemy, start ......"

With a thousand furnaces of elixir, Han Xiao had almost used up all the medicinal materials provided to him by Fu Chunyang's subordinates, and this time he was refining the same elixir - Rejuvenation Pill.

This pill is a healing elixir, a high-grade rejuvenating pill, and it is also a rare item that big families and chaebols can receive when they see it.

Pei Yuan Dan is also a kind of Pei Ben Zhengyuan pill, the dosage is very large, the top grade Pei Yuan Dan is a good pill for monks to urgently heal their wounds on the battlefield.

Now, the effect of the Rejuvenation Pill refined by Han Xiao is much better than that of the Pei Yuan Pill, because the Rejuvenation Pill can be said to be an upgraded version of the Pei Yuan Pill.

The medicinal materials refined by this Hui Sheng Dan and the difficulty of refining are far more demanding than those required by Pei Yuan Dan, but because of its good efficacy and fast healing speed, it has always been sought after by the upper class monks in the immortal cultivation world.

What is a high class monk?

An upper-class monk is a monk with status, status, financial resources and even strength.

Like Han Xiao, he has a reputation, but, strictly speaking, he can't be called an upper-class monk.

However, with a background like Zhao Tianxing, he can be called an upper-class monk.

However, Han Xiao didn't really care about this bit of fame, and he also cared about whether he was squeezed into the ranks of the upper class monks.

On Earth, Han Xiao, who used to be a top scientist, was also a celebrity, and the feeling of being a celebrity was actually like that in Han Xiao's opinion.

But the top-grade elixir is indeed a must-have item for high-class monks, and the top grade is also their pursuit.

As for the ordinary monks, what kind of low-grade pills and medium-grade pills will be used immediately. Even when it is not necessary, they are reluctant to waste the elixir......

Therefore, Han Xiao knew very well what he was refining now.

If it is successful, if it can reach the top grade, then this thousand furnaces of elixir will be a priceless thing.

Han Xiao calmly cultivated on the side, although his body was able to cultivate on its own all the time...... Well, self-cultivation is an automatic cultivation mode, and it is really wonderful to be able to achieve this realm.

The rune array monitored the whole process of alchemy, and Han Xiao monitored the rune array, and the hundred humanoid puppets stood neatly behind Han Xiao.

A thousand alchemy furnaces, if any of them had some abnormalities in the process of standardizing alchemy, Han Xiao would send a humanoid puppet to understand the situation and correct it.

The Tiangong Academy is currently an inaccessible place, so Han Xiao is doing alchemy alone, and no one comes to disturb him.

And his flying board team is cruising and selling in the Spirit Sword Sect, and many disciples in the Spirit Sword Sect are willing to buy it out of their pockets out of curiosity to try it.

Because of the fresh taste, and it is grilled with the meat of the demon birds and beasts of the Ten Thousand Demon Valley, it may be out of curiosity and hatred, plus the things are actually not expensive, and generally speaking, it is more economical and cheaper than the spiritual food in the spirit canteen, so many people are still willing to pay for it.

In addition, there are really a lot of monks in the Spirit Sword Sect, and the market is very large.

Therefore, those million demons seemed to be a lot, but compared to the huge group of disciples of the Spirit Sword Sect, the number was actually very small.
