Shi An happily put these newly made magic weapons into the storage bag, and took out a large pile of magic weapons and spiritual weapon fragments obtained in the crypt. These objects are now no longer effective except for some aura. The materials used in these objects should be relatively high-level, except for a few fragments that can be identified by the materials used, the rest are not recognized, if he wants to restore them one by one, he is not sure of this now.

With a sigh, Shi An put the things back into the storage bag.

The Flying Boat Artifact was taken out. The last time this flying boat was transformed by Shi An was when he was in the Four Elephants, mainly to increase the speed, and at that time, due to the limitations of technology and materials, only a low-level formation was arranged. Now in order to have a greater certainty of killing Sun Lang, a lot of improvements need to be made.

The low-level speed-up formation was replaced by an intermediate-level formation, not only was the speed of the flight faster, but more importantly, the speed of the flying boat was also greatly improved, and the frustration when turning was also gone. An intermediate defensive formation has been added, which should be able to withstand the heavy blow of Brother Yudan. In the end, he arranged an intermediate phantom array, which could completely cover the aura fluctuations of the flying boat when it was stationary, and transform into a cloud, but due to the limitation of materials, this could only be transformed into a white cloud of ten zhang in size, and it was impossible to blend into the background of the sky as a whole.

Even so, Shi An is already very satisfied with the speed, defense, and transmogrification functions of the current flying boat, and the transformed flying boat should also be able to be called a top-grade ground-level magic weapon.

He then completed a few more formations. The one originally made by the Misty Array Disc has been used up, and every time you need to get some burned-out rune paper, it is too troublesome to pretend to use the escape talisman, and now you need to make some improvements;

Because they had all been done before, it took half a day to complete four Dense Array Discs and ten Heavenly Eye Array Discs.

After putting all these into the Dongtian Stone, he finally took out the dagger that had been crumpled into knots, although it was no longer usable, but the materials used were still not difficult to decompose, so he took out several other intermediate materials, gathered enough of the five element attributes, and prepared to make a high-grade heaven-level long sword with five element attributes for himself.

He has never done a high-grade magic weapon, but the principle is clear, the reason why it is the same as the material used in the medium-grade magic weapon, but it can be classified as a high-grade one, is because it can change in size, and the root of all this lies in the refining skills, and more attention is paid to the space for the expansion of aura between materials. For example, if a flying sword is also made of medium-grade materials, if the materials made are very structured, then there is no room for aura to expand, which means that the size of the magic weapon made is the same as the size of the material used, which is a medium-grade magic weapon, and if the space between the materials is large enough, the original size can be supported by various attributes of aura, which is a high-grade magic weapon.

In terms of materials, the materials used for medium-grade magic weapons are far less than those of the same size after transformation, or in other words, the number of materials used to make a medium-grade magic weapon is comparable to the number of materials used to make several or even a dozen high-grade magic weapons, but in fact, the materials used by a refiner to make a high-grade magic weapon are several times or even dozens of times that used to make a medium-grade magic weapon, and the reason is that the failure rate is extremely high.

The reason for the high failure rate is that it is very difficult to grasp the size of the space between the materials, the degree of symmetry, etc. If the space is too small, the degree of change of the magic weapon is not large, and the power will be greatly reduced, and it is not a good high-grade magic weapon; too much space will make this magic weapon very fragile and difficult to meet the actual needs of the fighting method.

The symmetry of the space is even more critical, as the different sizes of the space not only make it difficult for the output of the aura to achieve the user's desired goal, but even cause the self-explosion of the magic weapon due to the different distribution of the aura pressure.

Multi-attribute high-grade magic weapons are even more difficult to make, if the two attributes are mutually reinforcing, it is better to say, if they belong to each other, then how to make the space between the various materials accommodate a balanced aura, and at the same time exert the effect is even more difficult. Therefore, as far as Shi An currently knows, there is no refiner who can refine two materials with the opposite attributes into a high-grade magic weapon.

For Shi An, the difficulty was even greater, because he was not refining a dual-attribute high-grade magic weapon, but a five-attribute one. If this idea is to let the shopkeeper Mao, no, even if it is known to the two grandmaster-level knot refiners in Wuluo Castle, it will be considered a fantasy.

After several failures, Shi An found that it was still a little unrealistic to refine it now, not because of unclear thinking, not because of unskilled techniques, but because there were too few materials that could withstand failure.

Ten days went by in a flash.

The grizzled Shi An walked out of the refining room, the long-lost sun shining on his face warmly, he raised his head and was enjoying a moment of leisure after a few days of hard work, but he heard someone shouting to him: "Zhao Daoyou, you can figure it out." ”

Turning his head, he saw the shopkeeper Mao looking at him anxiously.

"Shopkeeper Mao, what's the matter so anxious?" Shi An said puzzled.

"The second son is waiting for you in the living room. ”

"Then why didn't you tell me earlier?"

"I also wanted to call you, but the second son wouldn't let me, so I ......"

The two walked quickly into the living room, Wu Wei was quietly sipping tea at the moment, and when he saw Shi An coming in, he stood up.

"Senior Brother Wu, I'm really sorry to keep you waiting, when did you come?" Shi An looked at Wu Wei who was smiling, and hurriedly asked with his fists clenched.

"I've just been here for a while, I don't have anything to do today, I want to talk to you. Unfortunately, you are refining in the refining room, and you don't dare to disturb. Wu Wei said with a smile.

"Look at what you said, you only need to ask the shopkeeper Mao to call me, I can't afford to delay your big event. ”

"I heard from the shopkeeper that you are now trying to refine a higher-level magic weapon, and you have your own cultivation arrangement, if your plan is disrupted by my visit, it is not mine. ”

Shi An was a little moved, being interrupted during the refining process did have a very big adverse effect, which every monk knew. And it is probably something that few people can do to really take care of the arrangement of the refiner, although there are not many people who are as arrogant as Sun Lang among the visitors, but it is not nothing, so the head and face of a sect can do this, Shi An can't help but be moved.

"This second son is definitely not an ordinary family child, he is also honest to himself, and he is indeed a friend who can be made. Shi Anxin thought so, and expressed his gratitude in his mouth. "Senior Brother Wu, Senior Brother, how can I let you take such care, I am ashamed to accept it, I am ashamed to accept it. ”

"Senior brother is serious, I am very optimistic about your refining level, I only hope that you can further improve. I've always wanted you to enter the inner door, or give you better treatment, but I can't help because of the rules of Nai Fort. ”

The shopkeeper saw that the conversation between the two was not easy to disturb, so he quietly retreated.

"Senior Brother Wu, what do you have to tell Zhao An today?" Shi An asked.

"Senior Brother Zhao, I don't know how long it will take you to refine the best magic weapon?" Wu Wei said with a restrained smile.
