There are still thirty blessing gems left, and the system only has one chance to exchange them, and when the energy is consumed, they can't exchange things anymore, which is a bit of a pity. However, in recent months, a large number of spiritual materials have been refined in this strange world, many of which are magic materials similar to Mithril, so the demand for blessing gems has been reduced a lot, and only a few things still need blessing gems to be used as energy cores, such as the Dan Furnace is one of them.

Although you don't need to bless the gem, you can make a very good Dan furnace with just some magic materials, but the two elf girls are so well-behaved and obedient, since they want to give them a gift, of course they have to send the best.

Took out a large pile of Edman metal ore, Li Yunfei really likes to use this cheap metal, although this kind of thing is cheap but really easy to use.

This material was originally quite a noble thing, and once upon a time it could be exchanged for points, but this world is very cheap, and the fundamental reason why it is so cheap is that the stock is huge.

According to the Continental Chronicles, there is a place called the Falling Star Zone outside the Death Desert, and millions of square kilometers are full of Edman metal ore, and the reserves are several times larger than that of iron.

If it weren't for the fact that there were so many three-turn monsters over there, and only high-level trialists could go over to mine, this Edman metal might really be much cheaper than ordinary iron.

"By the way, how big do you want the Dan Furnace?"

"It doesn't need to be too big, we don't have much storage space, and we have to install other things, so it's better to make a small point of Dan furnace!" The two replied in unison.

The two of them have been together for a long time, and they already have a feeling of heart-to-heart when they speak, and many times they will speak in unison, which is even more like twins than twins.

"Then let's make an eighty-centimeter diameter one, and it's enough for ordinary refining pills...... So what are the basic requirements for the style? ”

"The captain is in charge, you are a master!" The two of them didn't understand this at all, and of course they didn't dare to talk nonsense.

"Okay!" After getting the answers of the two, Li Yunfei also began to make it, since there are no basic requirements, then he is in charge.

“…… Captain, can we go back...... There's also an elixir that is trying to cultivate! Seeing that Li Yunfei was making a Dan furnace by himself, the two of them were hanging here and didn't know what to do, and they didn't seem to be able to help much, so he couldn't help but say something.

"Since you guys don't have much interest in the formation, let's continue to study the elixir!" Originally, I wanted to teach them how to make a Dan furnace, but they were really not interested, so I went with them.

"Thank you, captain, if you have something to say!"

"Go ahead, something will call you, by the way, let the little dryad grow some yellow grass out, that one will be useful to me!"

"Understood, goodbye, Captain!" After getting Li Yunfei's answer, the two hurriedly said goodbye and left, the two of them really liked the development work of the elixir and the like.

……

It only took three days to cast the two Dan furnaces successfully, as for whether it is good or not, this has to be tried to know, but it is really good-looking in terms of appearance.

After the blessing gem was successfully inlaid, the glow array engraved on the Nadan furnace was automatically activated, and a dazzling colorful glow was emitted in an instant, reflecting almost the entire enchantment space.

Of course, this is only a temporary outbreak when it is just activated, and it will subside after a while, but even if it subsides, it can still emit a colorful glow, which is very charming.

The colorful light that erupted at the moment when the glow formation was activated alarmed the two girls who were developing the elixir formula, and they thought that something had happened, so they rushed over in an instant.

I was stunned for a moment when I saw the two Dan furnaces that flashed with colorful light, but then there was excitement, these two treasures must be the Dan furnace customized by the captain, such a beautiful Dan furnace, it is simply a perfect work of art...... Isn't it a waste to use such a perfect work of art for alchemy?

"Don't be stunned, come here, this Dan furnace has been made, you can take it and try it to see if it works!"

“…… Thank you, thank you Captain! The two of them could only keep thanking each other, and they didn't know how to express their excitement.

"Don't be so polite, try it to see if it works."

"It's easy to use, it's definitely easy to use, the captain is a master, can the things he make not work!"

"Don't compliment, if you have any questions, feel free to come and ask me."

"Thank you, captain, then let's go back first!" The two excitedly put away the Dan furnace, and after thanking them again, they each returned to their living quarters to try out the new baby.

……

The two girls went back to test the alchemy with great interest, and Li Yunfei also once again devoted himself to the study of the complex formation, the formation being studied was indeed very complicated, and he deliberately took a name, wishful change formation, in order to show the importance of this formation.

This Ruyi change array,It's been researched and deduced for months.,When I first learned from the dryad that the Ruyi change technique encountered a bottleneck, I began to develop this formation.,This time, if it wasn't for the magic elixir of the two girls.,I wouldn't have stopped studying this formation at all.。

Although he is always called a formation master by the two girls, in fact, Li Yunfei always feels that his formation knowledge is not enough, for example, this wishful change formation, it is still a thousand things after a few months of deduction......

But it's also strange to say, originally I felt that my brain was a little messy when I studied the change array, but after making two Dan furnaces for the two girls in the past few days, I suddenly found that my brain was much better, maybe it was a problem of changing my thinking, and there were a lot of new ideas. Don't miss the opportunity, quickly take out a metal disc and a large number of Mithril basic circuits, and start deducing. For a while, all kinds of strange energy field changes appeared on the metal disk......

There are energy circuits that control various color changes, circuits that control various force field shapes, and circuits that control the strength of various force fields......

Li Yunfei firmly believes that he can use the energy circuit to make a kind of equipment, as long as he wears it on his body and is driven by divine thoughts, he can make himself ever-changing, and he only needs to consume a trace of divine thought drive.

And as long as such a change formation is successfully developed, then only a certain amount of energy needs to be consumed, and it is no longer necessary to forcibly restrain the energy to simulate various shapes with a powerful divine thought, so the spiritual power consumed will be very small, or even negligible.

In the imagination, the equipment principle is somewhat similar to colored e-ink, after turning into a shape, as long as it is not destroyed or changed again, then the energy consumed is almost negligible.

It's just that it's really quite difficult to come up with such a complicated Ruyi change formation, but it is also difficult to get her out, because Li Yunfei already wants the real use of this formation.

That is, after the end of this task world, this complex can be engraved in the Jindan with divine thoughts and become a real supernatural power, which is the method associated with according to the system's introduction to the nine turns of the Jindan.

Completing the ultimate task will reward a kind of Jindan Nine Turns Secret Technique, this thing will be used as the ultimate reward together with the incomparably precious heart of the world, and it is also very valuable, so I deliberately searched for a long time from the system encyclopedia, although the system encyclopedia information is incomplete, I still found some introductions that are only a few words.

It is said that it is a kind of mysterious formation that can also be carved while casting Jindan, so as to obtain supernatural powers, and when the Yuan Infant is conceived in the future, all the formations engraved on the Jin Dan will be inherited by the Yuan Ying in the way of natal supernatural powers, which is very powerful.

So this wishful change array must push her out, with this wishful change ability, of course, the survivability can be greatly improved, just like the little tree demon barely reached the strength of the second turn, stunned by its natal change technique, seduce the monsters of the third turn everywhere, and easily walk in the group of monsters that are many stronger than themselves is really enviable.
