There is a difference in the difficulty of refining treasures, with Lin Heng's conditions, that is, the need for powerful and simple refining treasures, this can be described as everyone's pursuit, to put it bluntly, it is a sword!

When there is no sword, everyone's treasures can be described as varied, various, and extraordinary, but seriously speaking, the number is not much, generally in the hands of those masters, masters, like those ordinary monks, it is difficult to have a treasure of interest. Since the birth of the sword, the sword has become a must-have treasure for everyone, because the sword is easy to refine and powerful.

Such useful treasures are naturally sought after by everyone. Just to be honest, if the sword and other treasures of the same level, the general long sword is at a disadvantage, unless you are a sword cultivator, otherwise it is difficult to exert the power of the sword itself, let's just say the soul bell in Lin Heng's hand, it is a magic weapon, but the value is higher than the magic weapon level of the flying sword, what is it? It's because it's more difficult to refine and it's easier to use than a long sword, so it's expensive.

It's just that this kind of magic weapon is not something that anyone can refine and have, Lin Heng may be able to refine it, but that requires intensive research, after all, he is not a master of treasure refining.

Now he doesn't have the time, and he doesn't want to make a treasure with a bell or something, in his mind, the best treasure is still a long sword, just how to increase the power of the long sword?

After thinking about it for a few days, Lin Heng thought of the formation. Sword Formations are not uncommon in the cultivation world, but there are not many who can arrange Sword Formations to defend against enemies, because whether it is the sword used in the Sword Formation or the formations involved, it is not a simple thing.

A simple sword formation requires multiple long swords, especially when refining complex and mysterious formations, it requires double-digit long swords, so many swords, how can ordinary monks consume them? If others don't say it, just say Lin Heng, he has good assets. But when he cleaned up some materials, he could only refine seven or eight long swords, and if one or two of them made mistakes and the long sword was destroyed, then the materials would be wasted. He's like that, let alone everyone else.

Therefore, there are not many people who can refine the Sword Array.

Although he was worried about waste, Lin Heng still decided to refine the Sword Array. He wants to use the long sword as a treasure, but he is not a sword cultivator, in order to exert the power of the sword. Refining the Sword Formation is a must, and this can be his means of defending against the enemy.

After deciding, Lin Heng thought about what formation to refine?

Complex formations, Lin Heng can't refine, because he is not a formation master, but it is too ordinary, the power is too weak, even if the sword formation is arranged at that time, it will not be of much use. In order to be able to better fight the enemy. Take this as your own hole card, and the sword array you can refine must be good, but it can't be too complicated.

Sitting in the cave, Lin Heng carefully thought about the formations he had seen. After reaching the extreme, he chose the Five Elements Formation.

Among the formations in the world, the simplest is what are the formations of the three talents, the two instruments, and the five elements, which can be at the same time. This is also the most difficult formation to achieve. From ancient times to the present, the two yi arrays and the three talent arrays have been famous all over the world, but at that time they were in the hands of great powers. In the hands of ordinary people, have you ever heard of this prestige?

Lin Heng wanted to refine this array, but he didn't expect to exert great power, he only thought about the five elements principle. When he was punishing immortals, he practiced the five elements, and later became yin and yang. From this point of view, he can completely refine the positive and negative formations of the five elements of yin and yang. Of course, with his current cultivation, he can't refine the Yin and Yang swords, but he can completely refine the Five Elements Sword, and when he reaches the Yuanying realm, he will make up for the Yin and Yang to make the sword array evolve.

As soon as he thought of it, Lin Heng hurriedly left the cave mansion and rushed to the leylines around Fang City, and rented a good place for the leylines to refine his sword.

In order to refine the Five Elements Sword Array, Lin Heng took out all his worth, made up the required materials, and then devoted himself to the refining business. He first planned carefully, studied the formation, and only after he understood it did he start refining the sword.

Everyone understands the principle of the five elements of mutual restraint, but in the formation, it is not like that, such as the five elements of each other, that is, gold and water, water and wood, wood and fire, fire and earth, and earth and gold.

It can be said that the five elements change, and all kinds of truths are in this mutual restraint, and the five elements formation also has an infinite arrangement of methods, you can enter the formation, and if you don't understand the changes, you will break in, that is, you will find death.

The positive five elements mentioned above, that is, the use of the principle of mutual growth and restraint of the five elements to form a formation, so what is the reverse five elements? The so-called reverse of the five elements is the opposite. Of course, to arrange the reverse five-element formation, it is not just a theory. To arrange the positive five-element formation, you need all kinds of materials, and you don't need special layout, but you can arrange the reverse five-element formation, and you need special materials.

How does fire make wood? Among the five elements, water gives birth to wood, so what should we do if fire gives birth to wood? Simple, is to use the characteristics of fire to overcome gold, to dissolve gold with fire, to produce water with gold, and then to produce wood with water, it is still a shun, but what can be shown is the inverse, and if you want it to directly achieve the inverse, it is the condition of the fire and wood, then you need to start with the material.

This is also a manifestation of the role of the formation weapon.

When Lin Heng is refining the Five Elements Sword, he needs to follow the formation of his own thinking, his positive and negative Five Elements Sword Formation, with a Five Elements Sword as the mainstay, and the other Five Elements Sword each occupies one, usually against the enemy, the Five Elements Sword is the mainstay, and when the Sword Formation is cast, he will use the Five Elements Sword in his hand to control the Five Elements Sword to increase the power of the formation, and at the same time, he will carve the Five Elements Transformation Formation in the main sword Five Elements Sword, so as to increase the variation of the Five Elements Formation, in order to catch the opponent off guard when facing the enemy.

It seems very simple to say, but it is extremely troublesome to refine, the five single-line swords are still simple, just be careful, Lin Heng is a success, but when refining the main sword Five Elements Sword, he failed three times in a row, the first time because of the unevenness of the five elements, it was directly scrapped; Failed to depict the formation the second time; The third time, it was still a failure when portraying the formation.

By the fourth time, Lin Heng had finally succeeded, but the sword in his hand was far different from what he thought.

In Lin Heng's expectation, the Five Elements Sword should be black, because the five elements are one, which makes the color black, but if you look at the Five Elements Sword in his hand, it is clearly colored, and there is a touch of black in the center, which is the main material he prepared for the Five Elements Sword. It's a pity that although the sword body is there, the five elements of the material are not completely fused, making the whole sword six colors.

"I really can't imagine that it is so difficult to refine a good treasure."

Lin Heng sighed a little, but he couldn't help it. The sword array he refined was based on immortal materials, and the five single-line swords were okay, although they were laborious, they were also successfully refined, as long as they burned the law of the five elements in the future, they would definitely be able to evolve, but this main sword that contained the five elements became a semi-finished product. But don't worry, with Lin Heng's cultivation of the spirit, he can make the five elements in the sword slowly fuse, when the five elements are completely integrated into the sword body, the long sword will definitely take shape, and when the time comes, he will enter the law of the five elements at one time, and this sword will definitely become the best in the immortal weapon.

Putting away the six long swords, Lin Heng pushed open the stone door and walked out of the leyline cave. Breathing in the cool air outside, Lin Heng's somewhat depressed mood suddenly improved a lot, he covered his eyes with his hands, squinted at the sky, and had a faint smile on his face.

"This refining has been nearly three months, I really didn't expect it! I don't know if ......the White Stone Cave is open or not," muttered, Lin Heng turned around and fell onto the streets of Fang City. Compared to three months ago, there were many fewer people on the streets, and Lin Heng didn't have to think about it to know that those people must have rushed to Baishi Mountain.

Every time the White Stone Cave Heaven is opened, it is a major event in the cultivation world, the Yuan Infant Stage Monks, the Jindan Period Monks, the Foundation Building Period Monks, and the Qi Cultivation Period Monks will all rush to Baishi Mountain, and those who have the White Stone Order are waiting to be opened, and those who do not have the White Stone Order also care about these, as for what they have in their hearts, then only they know the Dao.

However, there is one thing you have to admit, that is, during the time when the White Stone Cave Heaven opened, White Stone Mountain was the most lively time in the cultivation world!

After walking around, Lin Heng didn't plan to stay here any longer, he directly rose into the sky and flew to the west. (To be continued......)
