The loss of the space formation and refining techniques made the space stone useless, and in the past, the space stone was a common refining item of each sect, not only the Yimen, but also the other sects also stocked.

For example, there are also space stones today, but there are many fewer of them.

Lin Qingwan wanted to use it, and the special department couldn't find it for a while, so she could only go back to Yimen to get it.

As soon as Yimen heard that Lin Qingwan was studying the space magic weapon, he didn't feel much distressed and took out a piece for Yi Han to take away, and waved his hand and said, "Just take it, come back and get it when it's not enough." ”

Yi Han glanced down at the space stone, which was only the size of a child's fist, and then at the head who seemed to be very generous, and twitched the corner of his mouth.

Lin Qingwan went to the research institute to collect a set of carving knives, found a piece of wood with a high hardness and began to learn the carving formation.

When carving the array, it is necessary to transport the spiritual power, to make the spiritual power continuous, the place where it passes can be connected into a line, and then hidden on the device, and when the whole set of formations is carved, the spiritual power can flow in series without hindrance, which is half the success.

The other half is to ensure that the formation is not lost and the spiritual power is not dissipated, only in this way can the opened up space in another dimension be able to exist forever.

When one day, the formation on the artifact is missing, or the spiritual power disappears or does not continue, the space that has been opened up will disappear, and the items inside will either be damaged or lost in the other dimensional space, and they will never be recovered.

Whether it is jade, spirit wood or space stone, it is very valuable, and even silk is not easy to obtain, so in order not to waste materials, she practiced first on this ordinary wood.

She is not skilled enough, although she can already draw the space circle skillfully on paper, but the use of a carving knife is always different, and it is even more difficult to maintain the continuous spiritual power.

Lin Qingwan practiced in the dormitory, and lost a lot of carved wood around her, and it wasn't until the third day that she carved the first piece in one go.

Lin Qingwan was slightly excited, after putting down the wood and the carving knife, she meditated and cultivated, emptied her divine sense, and opened her eyes refreshed for two hours, picked up the carving knife and another piece of wood and continued to carve until this piece was also completed in one go, she happily went to Yi Han and announced, "I carved it." ”

Yi Han was happy, "I made a report to the minister, the jade was taken from the ministry, and I also took the space stone, and I can start construction at any time." ”

He also said, "Although the space stone is only the size of a fist, it is not a problem to refine it more than ten times, and the jade is in the department, so you can rest assured that you can boldly test it." ”

So it doesn't matter if it's broken, they have money.

Lin Qingwan smiled brightly, "Then let's try it now." ”

She feels confident now and wants to do it right away.

Of course, Yi Han had no opinion, he had been making preparations for the past two days, and the things were all in his storage ring, so he immediately pulled Lin Qingwan and went to the research institute.

If you want to refine weapons, you can't do it in the dormitory, there is a special refining room in the research institute.

The fire used by the monks in refining weapons was either spiritual fire or alien fire, while the researchers in the research institute used natural gas, coal, and charcoal fire, although they had never succeeded in refining them so far.

But there are all the things that should be in the refining room, like Yi Han, when Fang asked them to refine some simple magic weapons, they would come over and borrow the refining room here.

This is likewise one of their perks.

Yi Han borrowed a refining room with his identity card, and then pulled her in and opened the defensive circle.

Then he took out the space stone and the jade that Minister Xu gave him to show her, "Choose a piece you like." ”

Minister Xu gave them a lot of jade, Yi Han put it in a box, and Lin Qingwan saw that there were seventeen or eighteen pieces, obviously fully prepared for failure.

There are new and old jade, without exception, it has only been polished, and has not been carved, so although the shape is different, it is all lumpy, large and small.

Lin Qingwan touched it piece by piece, it was very delicate and warm, obviously they were all high-grade jade, these were nephrite, and the price was not low.

Lin Qingwan put them out one by one, as her first work, of course, she had to choose them well.

After reading it and comparing it well, Lin Qingwan finally chose a piece of green jade.

This piece of green jade is almost round, tough and delicate, warm and subtle, and she thinks it must be nice to engrave a dragon on it.

Lin Qingwan pondered the green jade up and down, and finally pinched its corners, looked up and smiled at Yi Han, "Use this." ”

Yi Han: "Okay." He put away the other jade stones, picked up the space stone and pondered, "You don't know how to refine weapons, I'll help you." ”

Lin Qingwan let out a soft "um", and saw Yi Han wrapping the space stone with spiritual power, and the spiritual fire "soared" and burned under the space stone.

Lin Qingwan waited with the green jade.

Yi Han burned for a lot of time before the space stone slowly softened, Yi Han had a dagger on his left hand, and when the space stone finally became soft, he slapped his palm, the dagger flew up, and he cut it off with a knife, cutting a small piece at the edge of the space stone.

Yi Han threw the thumb-sized space stone into the flames and burned it, and took out the large piece and threw it in the air, and waited for its temperature to slowly drop before throwing it into the box and putting it in.

The small space stone in the flame softened at a faster speed, slowly softening into a puddle, and continued to be wrapped in spiritual power, kneading into various shapes by spiritual power, tumbling and burning at three hundred and sixty degrees.

Lin Qingwan saw that Yi Han's spiritual power was consumed too much, so she sat down beside him, holding his left hand with one hand, and the spiritual power was transferred from her to him.

If it was someone else, the spiritual power transitioned, and the other party might not be able to turn the spiritual power into their own, but this was not difficult for Yi Han and Lin Qingwan.

Because they have been cultivating together, their spiritual power is rotated between the two, so each other's spiritual power is very affinity, Lin Qingwan's spiritual power entered Yi Han's body, and it was only after walking half a circle of meridians that it could converge in his dantian, which was faster than taking drugs to maintain spiritual power.

And there are no after-effects and side effects.

Yi Han smiled at her and continued to refine the space stone.

Space magic weapons are above the sixth grade, and they can generally be refined by refiners with Jindan and above cultivation.

Because not only does it take a lot of spiritual power to depict the formation, but it also takes a lot of spiritual power to refine the weapon.

In an era when refiners are all working alone, it is impossible to stop refining at the beginning, so it is necessary to ensure that the spiritual power is used sufficiently.

Therefore, the larger the space magic weapon refined, the greater the spiritual power required, and the higher the cultivation required of the refiner.

Now, whether it is Yi Han or Lin Qingwan, their cultivation cannot be reached.

However, they were two people working together, one was responsible for one step, and the two of them had already calculated the amount of spiritual power needed to be consumed by the alchemist at the beginning, and theoretically, they could refine it.
