Yang Quan encouraged himself in his heart, and then began to think carefully about the practice of the template, since it is to assist in writing runes, it must not be too thick.

Secondly, it must be able to isolate mana, and it must be suitable for hollowing, this material is not easy to find, flying all the way from Cangzhou to Luzhou, the journey lasted more than half a year, and it can be regarded as a bad supplement to the common sense of cultivating immortals in this world, and the basic materials are still understood.

There are a lot of metal and mineral materials that can isolate mana, but this kind of thing is very troublesome to hollow out, they are all materials for refiners, and the hardness is excellent, and it is not easy to hollow out, so it is discarded.

Plant-based materials are more suitable for hollowing, but they are not easy to collect, they are all very precious alchemy materials, which are worth a lot of money, and Yang Quan can't afford them at all, so he only has a spirit stone.

And then there's the skin of the demon beast, the skin of some demon beasts, it has a certain effect of isolating mana, although this kind of thing is also expensive, but as long as it is a small piece the size of the rune paper, it is not that it can't afford it, in writing two or three months of rune paper, get a few spirit stones, it should be possible.

It's also heartfelt when I really think about it, just such a small piece of demon animal skin, he has to save money and work for several months. But this is also something that cannot be helped, and it is very difficult to get started.

Just met a friend and left a few days later, Yang Quan was slightly depressed in his heart. From that day on, in addition to continuing to write rune treasures every day, he also had to take time to learn carving and hollowing on ordinary paper, after all, it would take two or three months to live such a precious animal skin, so he couldn't be cautious.

The leaves in the courtyard gradually turned yellow, and then fell in a slump, the price of animal skins was higher than he imagined, he saved four months of money to sell rune paper, and then he got such a small piece of animal skin from the material store, it is said that it is to make a certain piece of armor leftovers, the material store owner can not bear his soft grinding and hard foam, and this leftover material is really useless, so he gave it to him at a low price.

Although he had been practicing for four months, Yang Quan was still not 100% sure about carving thousands of rune hollows on the animal skin.

Yang Quan drew the runes on an ordinary piece of paper, and after carefully checking them several times to make sure that they were correct, he fixed them on the animal skin, and then fixed the two together to avoid loosening. Finally, I bought the best carving knife and got to work.

For more than two weeks, he seldom went out, and did not continue to make runes, concentrating on carving animal skins and hollowing them out at home.

When the first snowflakes fell in this small border city of Luzhou, he finally finished his work, and he had hollowed out thousands of rune-shaped hollows on top of the animal skin. This is the fifth year that he has come to the world of cultivating immortals, he has been in the Lingtian for more than three years and two months, in the Yang family for two or three months, and from Cangzhou to Luzhou, it took nearly eight months, and in this small city, just writing rune paper, it has been more than half a year.

An animal skin is only the size of a palm, and thousands of hollow runes are on it, Yang Quan's slightly insufficient sunlight looks at it, and there are countless looming hollows on it, revealing a very peculiar picture, the hollow runes are hollow, like thousands of words, hooked together.

"Try it, you must succeed, otherwise it may take half a year to make such a small thing again..."

Yang Quan took out a small square box, this small box was transformed by him, there was no lid on it, only a circle of pressed wooden strips pressed. Lifting the pressed wooden strip, Yang Quan overlapped a blank rune paper with the animal skin, put it in, flattened it, and pressed it with the strip.

Yang Quan held the spirit pen in his hand, and used his spiritual sense to command the mana to follow the manual, relying on muscle memory, quickly writing in the hollow place, this time he didn't need to be careful, because if there was a mistake, the animal skin would help him change it, as long as he didn't miss some runes.

Because he had written tens of thousands of times, these runes were written like flowing water, and it only took two or three minutes for Yang Quan to finish writing.

He couldn't wait to take out the rune paper, went to the courtyard, and threw it at an open space.

“...”

The rune paper fell to the ground, and nothing happened. Yang Quan's hands trembled, he didn't expect this to be the result, he stepped forward and picked up the rune paper that had not been successfully excited on top of the snow.

"Why?"

Yang Quan didn't understand, why did he fail? Isn't the so-called rune treasure a combination of runes that produce various effects? Why did it fail?

Half a year, a full half a year, he really completed an idea, this is a failure? The question is where? Yang Quan stood in the courtyard, letting the snow fall on his body, and meticulously checked the runes on the rune paper with his spiritual sense, one by one.

"Hmm!"

I see, Yang Quan breathed a sigh of relief, it turned out that there was a place on the rune that should not be hooked, because when the animal skin was hollowed out, it was accidentally hooked together, so the entire rune system in front of him was invalid.

This is also something that can't be helped, although I have been learning carving and hollowing for half a year, but after all, I do it in my spare time, and I can't do it perfectly.

Continuing to check down, Yang Quan found another mistake, this time there was a place that should be hooked together, but it failed to be hooked together.

"It's okay to show the mistakes in total, but when you write with a mold, avoid these two places and just write at the end. "Yang Quan is a little relieved now, the mistake is not very serious, there is a remedy, just modify the mold, just write those two runes after each rune treasure is completed, and it will not be delayed for a few seconds.

Started to write through the mold again, those two wrong places, Yang Quan jumped directly, two minutes later, the rune writing was completed, Yang Quan took out the rune paper, carefully wrote in those two places, and came to the courtyard again.

Without hesitation, facing an open space, Yang Quan activated the fireball technique.

"Boom!"

A fireball exploded in an instant, sweeping away the thin layer of snow on the ground. Yang Quan looked at this scene and was stunned for more than ten seconds before he looked up to the sky and laughed.

He succeeded, the significance of this experiment is beyond imagination, and Yang Quan seems to be able to see his future. The rune treasure of the fireball technique is one of the simplest rune treasures, there are not ten pieces that can be exchanged for a spirit stone, and a hundred blank rune papers only need one spirit stone, which is almost ten times the profit!

And now that there is a template, the only places that really need to be carefully written are the two places that are sketched at the end, and the chance of error is almost equal to zero, even if the mana consumption is counted, the profit he can earn is quite objective, and now it is too fast to write a rune, twenty or thirty times faster than before, at least nearly two hundred runes can be made every day, and it is estimated that it will only take five or six hours!

It's not that he can't make more runes, but the mana in his body is limited, and if he makes two hundred pieces a day, the mana in his body will be exhausted, unless there is something better than Lingmi to replenish it.

Of course, now that the template has been successfully made, then there is definitely no need to worry about the immortal cultivation resources in the future, Lingmi is really bad for him, and he can try the spirit grass or pill in the future, and he can't continue to stay in the early stage of Qi training.
