"As for the Great Seal of the Son of Heaven, it has the power to intimidate people's hearts and nourish the spirits. ”

Zhao Yu said a few rough words, explained the wonderful use of the two magic weapons, and said: "From now on, the Five Elements Array Banner can be given to the general of the army in the middle of the battle." As long as you have to hold the Xuanyuan Sword, the Five Elements Array Banner will be made for it. As for the Xuanyuan Sword and the Seal of the Son of Heaven, I have already refined them for you before, but you still need to drip essence blood before you can use them like your arms and fingers. In the future, only the descendants of your bloodline will be able to use these two magic weapons. ”

At the previous founding ceremony, when he was pretending to be a god and a ghost, that purple light entered Cao Mengde's eyebrows, which was Zhao Yu's move to help him refine.

"These two magic weapons are much higher than the Five Elements Array Flag, and they don't have to be taken to other courtyards every three or five years to cultivate. Over the years, my cultivation has deepened, and the refining of magic weapons has been quite easy, and all of them have entered the forbidden law of Nayuan, but I can always absorb the Yuan Qi of heaven and earth, unless it is destroyed by external forces, otherwise the mysteries of the magic weapons can be guaranteed. ”

Cao Mengde laughed heartily when he heard this.

The two found a secluded place in the imperial garden, sat opposite each other, and talked until dawn. In the meantime, he talked about the popularization of medicinal herbs and pills, about the cultivation of martial arts, about the short things in his family, and occasionally let out a few laughs, which was quite abrupt in the quiet night, so that Dian Wei and Xu Chu, who were following in the distance and hiding in the dark, scratched their heads.

As for the sunrise in the east, Zhao Yu drifted away.

Cao Mengde looked at the direction of Puyang, and his face was full of emotion.

Back in Taihe Courtyard, within a few days, the sword embryo was delivered.

When it was delivered, it was sealed in an extremely heavy gold and jade box, but it was still difficult to hide its fierce edge. The generals and soldiers who escorted the sword embryo were all pale, and they were clearly invaded by the evil qi.

Zhao Yu collected the sword embryo, sent them away in order to rid the school of evil, and began to concentrate on refining this flying sword.

In the past ten years, this sword embryo has been on the battlefield, and I don't know how many killings it has experienced, and how many iron-blooded and dead Qi have gathered. In the originally crystal clear sword embryo, there were two evil qis, one red and one black, clearly coiled.

The black and red rays are faintly revealed, intertwined with the edge of the sword embryo itself, and if ordinary people look at it, they will be damaged and even damage their souls.

Zhao Yu took out the sword embryo, held it in his palm, and couldn't help but nod with satisfaction.

The flying sword that Zhao Yu wanted to refine was not at all comparable to the so-called Five Elements Array Banner and Xuanyuan Sword. Previously, all kinds of magic weapons were refined, because they were used by mortals, and considering Cao Mengde's ability, although there were also several law prohibitions, they were all weakened versions after deletion.

Just like the Xuanyuan Sword, although there are six law prohibitions, compared to the magic weapons that truly contain the six perfect law prohibitions, the power difference is ten times.

As for the Five Elements Array Banner, it was just a practice of the early refining weapon, and it was much inferior.

At present, this flying sword is the best magic weapon that Zhao Yu decided to refine when he had the intention of walking in the starry sky. Whether it is the material or the refining method, it is not the same.

Now that the embryo has been formed, the first step is to refine more spiritual materials and increase their quality.

In the past ten years, Zhao Yu has collected a lot of materials, including real spiritual materials such as iron mother and jade mother.

Iron Mother Jade Mother, Zhao Yu will not use all of them on a flying sword. On the premise of not destroying the vitality of the iron mother and jade mother, you can take some corners. The other is to refine some high-quality semi-spiritual materials, and refine them into the sword embryo one by one according to the method of refining.

In refining magic weapons, materials are one of them, and forbidden methods are the mysteries.

The best magic weapon, to hook the forbidden method to weave the thirty-six layers of the law forbidden, how to crochet, this is the most difficult place.

Flying swords are mainly killed, so when refining, increasing their damage and edge is the first priority. Cultivating the sword embryo with the battlefield is the first step. Later, various materials are added, either to increase its strength, or to increase its solidity, or to increase its edge, all around this one core.

However, the best magic weapons are not only strong and sharp. The so-called rigidity is easy to break, and the combination of rigidity and softness to be refined is the wonderful.

Zhao Yu's experience in the illusion of Tianyan Mirror, although it is true or false, but his experience is so profound that it is difficult to guess. In the Tianyan Mirror Illusion Realm, the Immortal Dao has undergone development, and many branches have extended on the refining tool.

Zhao Yu pondered and deduced, combined with the experience in the illusion of the Tianyan Mirror, and based on his current Taoist heritage, he planned to refine this flying sword into a virtual and real duality.

To refine the real into the virtual, so that this flying sword can be transformed between the virtual and the real, Zhao Yu's current mana realm alone can't do it. But it can be replaced by other methods - such as spatial mystery.

Refining this flying sword can shuttle through the void, although it is not really a real virtual and real wish, but it can be regarded as a combination of rigidity and softness.

If you have a flying sword, you can shuttle through the space with a snap of your fingers, and in an instant you will go around the opponent's side, and the big head will fall off your shoulders with a grunt.

If the opponent resists, the flying sword can appear and disappear from time to time, and it is not hard and rigid, which is the magic of rigidity and softness.

And to realize this idea, the key lies in the prohibition of the law.

This refining, just the first step of refining into spiritual materials, took Zhao Yu three years. When refining the embryo into the spiritual material, there are many important points. It's not that you can refine the essence of spiritual materials at will, it's just a pile of iron and stone, which is completely useless. When refining, it is necessary to follow the five elements of yin and yang, and the phases between the spiritual materials must be born and born. Otherwise, not to mention refining waste iron and stone, even the conflict between spiritual materials, and the explosion of Yuan Qi is idle. It will even break the embryo and waste all the previous efforts.

It took three years.

After the sword weapon is initially refined, the embryo that was originally only the size of a palm is now more than a foot long, like a door panel.

Only then did the second step of refining begin—entering the forbidden law, and the crochet method being forbidden.

The first appearance of the best magic weapon is the size of the ruyi. Of course, there is a limit to this size. The best magic weapon, no more than a hundred zhang, no more than half an inch small, and the magic weapon can not be compared. But this is the appearance of the best magic weapon, and it is also where its foundation lies.

Therefore, the first layer of legal prohibition is the wishful prohibition.

After refining into this layer of law forbidden, this flying sword has the performance of a large and small wishful spirit. After refining the instrument, you only need to think about it, and it can be big or small.

Ruyi Prohibition is simple to say, but in fact, the basic prohibition level of the Dutianyun Forbidden Law sorted out by Zhao Yu belongs to the most profound category. It involves the mutual stimulation and transformation of mana, Yuan Qi, and matter, which is extremely complex.

And this process of transformation needs to be achieved by legal prohibition.

This first layer of legal prohibition alone took Zhao Yu five years.

From retrieving the sword embryo to refining the first layer of Ruyi Forbidden, it was eight years in the blink of an eye.

In the past eight years, when Zhao Yu was short of refining tools, he also took the time to sort out the basic Dao pattern, and already a few years ago, the basic Dao pattern was fully perfected, and Guan Hai was sent to Luoyang and handed over to Cao Mengde.
