The head of the sect put aside this sentence, picked up the three chain paper cannons and turned around and left, leaving only the three elders to look at each other.

Now that the heads are gone, there is nothing to do with the rest of the people.

Fu Yun followed Wang Jianghua and first came to the Foreign Affairs Management Office and told him the requirements for what he needed.

This thing should be the same as the spirit stone, and the volume should be larger than the spirit stone, and the price should be more affordable than the spirit stone.

Wang Jianghua pondered, there is really this kind of thing in the sect warehouse, but no one uses it now.

This kind of thing is called a spirit foundation stone, and it is a kind of thing that is dug in the process of mining spirit stones. The spirit foundation stone is the same as the spirit stone, it can be used as the transmission of the spirit stone, and it also has a characteristic that it has no attributes.

Because the spirit foundation stone is an associated mine, the output is quite small, and the use is not large, so few people collect this kind of thing.

The spiritual cornerstone in the Qingcheng Sect's warehouse has always been there, and no one has ever exchanged for it.

This stone contains very little spiritual energy, much less than a low-grade spirit stone of the same size.

For the monks, this kind of thing is big and stupid, and it is not good to use it if it is placed in too many places in the Qiankun bag, so no disciple has exchanged points for it so far, and it has been idle in the warehouse.

Since Fu Yun is in need, he will give it to him directly.

Steward Wang pondered that it was useless to keep it anyway, and besides, the head of the house had already spoken, so Fu Yun could mention it if he needed to.

This whole spiritual cornerstone is a transparent rectangle, which at first glance looks like a large crystal, and the entire spiritual cornerstone is transparent, which contains pure attributeless aura.

The advantage of attributeless aura is that no matter what kind of exercise the monk is practicing, it can absorb it.

For Fu Yun, no matter what attribute the spirit rune is, it can be used to engrave seals and create runes.

Looking at the size of this spiritual foundation stone, it is not a problem to use it to carve the spiritual pattern template.

It's a treasure made for the printing business.

Fu Yun was holding the rectangular spiritual foundation stone, as if he was holding a child. If it weren't for the fact that the king was in front of him, he really wanted to kiss the two spiritual cornerstones.

With this thing, you can reverse-engrave the spiritual frame of the paper cannon. When you want to draw a spirit pattern, you only need to aim at the rune paper and cover it hard.

The role of the non-attribute spirit cornerstone is not only that, it is engraved with spirit patterns on the front, and various attributes of spirit patterns can also be engraved on the back.

Since the spirit foundation stone is not limited by attributes, Fu Yun wants to try to connect the spirit runes of different attributes together and inlay them in the gap of the spirit pattern at the same time.

He didn't mention this idea to Steward Wang for the time being, because he didn't know if the idea would succeed, so he had to test it himself.

After taking away the spirit foundation stone, Fu Yun took out fifty top-grade spirit stones from Steward Wang, and he was still thinking about the hundred-year-old pink mahogany that was about to be auctioned at the black market fair.

The speed of the shuttle is not high enough, even if it is only used to rush, it is too time-consuming, and it is even slower if you encounter a strong enemy to escape.

Fu Yun was going to make a new peachwood spaceship this time, and he was going to change some of the runes on it.

In the past, you couldn't add too many wind runes, but they were limited by rune paper materials, and when you get a new material this time, you must add more wind runes.

Back in his room, Fu Yun couldn't wait to take out the spiritual foundation stone.

With such treasures, the speed of making paper cannons will be greatly increased in the future.

The runes have always been directly sealed, but the spirit patterns still need to be drawn one by one, which is a waste of time.

I must get the template of the spirit pattern out tonight, and in order to make more money in the future, I have to work hard now.

There is no risk of explosion in the engraving of the spirit pattern, but there is only one piece of the spirit foundation stone, and if the carving is broken, it will be difficult to find the second one.

Although Fu Yun had successfully drawn the spirit pattern many times before, he still didn't directly carve it on the spirit foundation stone, but first took out the rune paper.

Medium-grade rune paper also has to be bought for money, but it is not as valuable as the spirit foundation stone.

Taking every drawing work seriously is Fu Yun's basic requirement for himself.

The tip of the talisman pen gently crosses the paper, and the lines are as smooth and graceful as ripples.

Fu Yun breathed evenly and his body relaxed, and he no longer had the nervousness he had when he was a novice, but only focused eyes and skillful techniques.

From the beginning of the paper to the completion of the pen, there is no jerky feeling in one go, and the process is almost perfect.

"Good!"

Fu Yun put down the talisman pen with a sigh of relief, picked up the talisman paper and looked at it carefully. Very good and neat, every spiritual pattern is so beautiful. In the past, the goal of drawing was to make no mistakes, just like writing without typos. What Fu Yun pursues now is not error-free, but neat and beautiful and even perfect.

The next step is to engrave the spirit pattern template, the template is not as small as the seal, and the texture of the spirit foundation stone is also relatively hard, so it is more difficult to engrave. Fortunately, there are black needles, otherwise I really don't know where to buy such a sharp carving knife.

Fu Yun planned to engrave the spirit pattern template deeper, because in the future, it would not only be used on rune paper, but also on other materials.

For example, wooden materials need a stiffer template to print. And the engraving must be deep to be able to print clearly and completely.

The tip of the needle moved steadily on the spiritual foundation stone, and some stone chips fell down with the movement of the needle tip.

Fu Yun pinched some stone chips with his fingers and rubbed them between his fingers. The paper scraps have a delicate texture, a large density and a slight stickiness, unlike ordinary dust, which is suspended and basically cannot be blown by a small wind on the desktop.

The material of the spirit foundation stone is usually rare, and there is only one spirit foundation stone in a vein mine that collects spirit stones.

The size of the spiritual foundation stones varies, but they all have one common feature, that is, they do not contain much aura.

That's why it's so rare, but so few people collect it.

The monk uses the spiritual stone as the basic trading currency, because the spiritual energy it contains is the most needed thing for cultivation, and it is much faster to obtain the spiritual energy from a spiritual stone than to absorb it from the natural world.

The higher the grade of the spirit stone, the more spiritual energy it contains, and the easier it is to absorb.

Although the aura contained in the spiritual foundation stone is very pure, the amount is really small and pitiful, and it is basically not helpful for cultivation.

At the beginning, there were monks who thought that the spiritual foundation stone was a kind of treasure, and kept it around and studied it often, hoping to find out what was different about it.

But as time goes by, everyone finds that this kind of thing has no other role except for being an intermediary for the transmission of aura, and the spirit stone and many materials can do this kind of thing as an aura transmission intermediary, and there is no need to spend so much effort to find the spiritual foundation stone, so gradually no one uses the spiritual foundation stone.
