Back in his house, Yuan Tian couldn't wait to take out the spiritual foundation stone. With such treasures, the manufacturing speed of paper artillery will be greatly increased in the future. The runes have always been directly sealed, but the spirit patterns are drawn one by one, which is a waste of time.

Tonight, we must get the template of the spirit pattern out, for the sake of happiness in the future, we 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 it can be broken, it will be difficult to find a second piece. Although Yuan Tian had successfully drawn the spirit pattern many times before, he still did not 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 the basic requirement of Yuantian for himself. The tip of the talisman pen gently crosses the paper, and the lines are as smooth and graceful as ripples.

Yuan Tian breathed evenly and relaxed, and there was no longer the tension that 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.

"Okay!", Yuan Tian put down the talisman pen with a sigh of relief, picked up the talisman paper and took a closer look. 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 Yuantian 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. Yuan Tian 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. Yuan Tian pinched some stone chips with his fingers and rubbed them between his fingers. The paper scraps have a delicate texture, a high density and a slight stickiness. It is not suspended like ordinary dust, and it is basically not blown by a small wind when it is attached to the table.

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 spiritual power. This is also the reason why it is so rare, but few people collect it. The reason why the monk has used the spirit stone as the basic trading currency is because the spiritual power it contains is the most needed thing for cultivation. Obtaining spiritual power from a spirit stone is much faster than absorbing it from nature. The higher the grade of the spirit stone, the more spiritual power it contains, and the easier it is to absorb.

Although the spiritual power 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. As time passed, everyone found that this kind of thing had no other role than being an intermediary for the transmission of spiritual power. There is no need to go through so much effort to find a spiritual foundation stone for this kind of thing, and there is no need to go to great lengths to find a spiritual foundation stone.

The monks who gave up the spiritual foundation stone at the beginning probably didn't expect it. Right now, there is a thin man carving a template out of the Spirit Base Stone, which will produce a large number of rune paper cannons, and directly affect the human war against the demon beasts.

Greatness often begins with imitation – the source of heaven

This is the motto of the source of pork ribs, whenever he likes something, he will first get a few imitations. Then figure out ways to improve it and make it more powerful.

The arm-long spirit pattern template was carved by Yuan Tian in this way. Between the spirit patterns, there is a "void" inlaid with purple fire runes, defense runes, and solid runes. At the end of the spirit pattern, there is also a place reserved for a little connection. That's exactly how Yuantian created it, and he can put a water amulet on it. In this way, even if the paper cannon is placed outside for a long time, it is not afraid of getting wet in the rain.

The defensive shield will only be activated when the cannon is about to be fired, and if you want to be waterproof, the water abode is undoubtedly the best choice. Because this kind of rune consumes very little spiritual power, it can be used for a long time in a single infusion. If several runes are linked together, even if they are not infused with spiritual power for several months, they will not be invalid.

Yuan Tian held the spirit pattern template in his left hand, and gently stroked the carving on it with his right hand, feeling every change in it with his fingertips.

Who the hell invented such a thing as a spirit pattern, the first person to use a spirit pattern is simply too smart. The runes originally worked alone, but since they had spirit patterns, they could be connected together and play a role several times or even dozens of times.

There is another person who is even bolder than the person who invented the spirit pattern, that is a thin man named Yuantian, who actually directly connected the runes next to each other, leaving no gaps in the middle. Even if multiple runes don't need the help of spirit patterns, they can also play a multiplier effect.

The way to integrate the two methods of spirit pattern and rune chain is now a way that has never been seen in the cultivation realm. Maybe the monks haven't realized the horror of this method yet, and when the chain second-order rune paper cannon, chain third-order rune paper cannon, and even chain spirit gathering cannon are created in the future, it will cause a change in the cultivation world.

While looking forward to the beautiful prospects, Yuan Tian used the spirit pattern template to print the spirit pattern on the rune paper. It's really convenient to have a template to engrave, and pressing it down at once is a complete set of spiritual patterns required for paper artillery. Tomorrow, after taking these half-finished paper cannons and stamping them with the three runes of purple fire, defense, and solidity, the complete interlocking paper cannon will be declared a success.

Printing spirit patterns in the house at night and going to the cave to stamp the runes during the day greatly improves the production efficiency, and you can save time to study the other four attributes of the five elements of the rune paper cannon.

Dozens of spirit patterns of rune paper were printed in one go, and Yuan Tian was a little sleepy. The body is the foundation of everything, so let's sleep first. Anyway, I have a good way to fall asleep quickly, which is to recognize the sword intent in the sea that specializes in torturing people.

Yuan Tian changed into a loose and comfortable suit, lay on the bed and covered himself with a quilt, and then entered the sea of knowledge.

Let the storm come more violently, oh no! let the sword intent come more violently. Yuan Tian looked like he was righteous and generous, and even the Kyushu Golden Dragon was bluffed by him.
