In fact, it's not that difficult to say, it's just that Yuntian didn't think in this direction before, but now that he has thought about this point thoroughly, he has a clear direction to explore.

The five-grade rune and the four-grade rune both belong to the middle-level rune, and their media are both red paper runes, so there is not much difference in the refining technique, and the specific difference is mainly reflected in the controllability of the rune.

A good talisman cannot be used only by refiners, but also by other users, which is the biggest difference between a five-grade rune and a four-grade rune, and the value of a five-grade rune is reflected here.

Five-grade runes, the more representative ones are fire runes, wind runes, rock breaking runes, armor-breaking runes, etc., Yuntian also plans to start with these kinds of runes and try to complete the refining of five-grade runes.

The characteristics of the fire talisman are naturally fire attacks, in fact, the attack power of the five-grade fire talisman is not as powerful as the thunder talisman, but one of the characteristics of the fire talisman is that it can cause delayed destruction, that is, if you throw the fire talisman on the mountain, it can ignite a large mountain fire, and you can also use some flammable materials to expand the effect, while the thunder talisman can only use its own power, which is naturally much worse in comparison.

The Wind Charm is more distinctive, it can form a stable wind, it has more functions, and it is also very practical in some specific environments. For example, when there is no wind, the boat will move very slowly, but once the wind charm is attached, the speed of the boat will increase, which can also reduce a lot of pressure on the boatman. Even when facing enemies, the Wind Charm can quickly accelerate the speed of the ship, thus getting rid of the enemy.

The Rock Breaker is able to break through a rock and enter it, although it is not very powerful and can only break a small area, but it is enough. If you encounter a strong enemy in the mountains and are forced into the mountains, you urgently need to find a place to hide at this time, and use this talisman to quickly dig a hole in the solid rock, and people can also hide in it to avoid the harm of fierce beasts.

And the armor-piercing talisman has its own unique role, the armor-piercing talisman as the name suggests, is to break the armor, of course, since it is a five-grade talisman, it is impossible to simply break the opponent's armor on the battlefield, that kind of small things with a bow and arrow, where to use a powerful talisman. Where the armor-piercing talisman is applied, there are some fierce beasts with strong defense, the kind of fierce beasts that are not injured by swords and cannot be cut into thick armor by axes, generally speaking, ordinary martial arts are often helpless against it, and when they encounter this kind of fierce beast, they can only turn around and run away, but if they have an armor-piercing talisman, they can easily penetrate the outer armor of the fierce beast, and then they can cause damage to it.

These kinds of talismans, their main role is to fight in the wild, it can be said that it is a necessary talisman for martial arts to practice outside, at least with these talismans, when practicing in the wild, if you encounter danger, you can have more opportunities to escape, if it is paired with a thunder talisman, it can be said that you can increase your chances of survival several times, it is no wonder that even those deacons are eager for Yuntian.

These kinds of talismans have their actual value, and Yun Tian naturally wants to refine them, but he first chooses the fire talisman, because he is the most proficient in the control of the fire system true qi, and he also has the most confidence in his heart.

In fact, in addition to this kind of attack talisman, there are also some gain-type talismans that are more popular, the problem is that Yuntian's identity is not only a talisman master, he is also a high-level Dan master, and the pills refined are at a higher level than the talismans, and the effect of those gain-type talismans at this time is far inferior to his pills. After all, Yun Tian's energy is limited now, and he can't spend all day in this Moyang City, he still needs to go out to practice earlier and speed up his growth in the experience, so that he can get closer and closer to his goal.

Ordinary rune masters, at this time, will mainly use five-grade gain runes, because this kind of runes are easy to refine, and the price is low, so it is naturally easy to sell, but Yuntian is not interested in increasing different types of runes, so he directly chose these attack runes.

Now his first target is naturally the five-grade fire talisman, this kind of talisman is the most popular among all the attack talismans, because the fire talisman is powerful and powerful, and it can often overwhelm the enemy from the momentum, and it is also enough to pull the wind when PK, and many advantages naturally make this talisman very popular.

The texture of the rune array had been printed by Yuntian in the Library Pavilion before, but now that he was slightly familiar with it in his heart, he was able to accurately grasp its trend.

The fire rune is different from the thunder rune, and there is no need to store the thunder true qi, because the fire element is widely present in nature, and there is no need to store a large amount of it in the rune, so naturally there is no need for red silk rune paper, only ordinary red rune paper is needed.

The requirements for materials were already much lower, and the control of the fire-based true qi was also much easier than that of the thunder-based true qi, because Yuntian himself, as a Dan master, had a perfect control over the fire-based true qi.

In this way, put the red rune paper in his hand, send a wisp of spiritual consciousness in, and then lift the rune pen and draw at high speed on the red rune paper, but it is just a moment of effort, and a formation pattern is drawn, although the drawing of the formation pattern is not perfect, and the rune can only become a waste rune, but after all, after this attempt, the next drawing is much easier.

In the second drawing, Yun Tian successfully drew a high-quality talisman paper, and then injected a little fire true qi into the talisman to keep the talisman active, all of which was completed very smoothly.

But in the end, Yun Tian was a little hesitant in terms of infusion. Although the fifth-grade runes are only middle-level runes, after all, the runes above the intermediate level need to use the beast spirit for spiritual injection, which is why the number of runes above the fourth grade is scarce, because in the absence of the beast spirit, it is impossible to refine the runes above the fourth grade.

Any rune master, as long as he can refine more than four runes, must have his own source of beast spirits, or he can have the means to collect beast spirits, maybe he can only collect very rudimentary beast spirits, but this is enough, primary beast spirits, at most, affect the quality of some runes, but can also refine more than four grades of runes, but if there are no beast spirits, then no matter how deep the cultivation skills of this rune master, he will not be able to refine the beast spirit.

Different from the dilemma of those talisman masters, Yuntian at this time has as many as two options, one is to use the beast spirit of the fire beast in his sea space, and the other method is to inject his spiritual sense into it, his spiritual sense grows quickly, and he is not worried about being exhausted, but the characteristics of this use of spiritual sense are more shocking, if it is discovered, it will indeed cause some trouble.

However, there is also a disadvantage in choosing the fire-type fierce beast beast spirit in the sea knowledge space, if a large number of refining is needed in the future, the fierce beasts in the sea knowledge space will obviously not be enough, and the fierce beasts in the sea knowledge space have a high growth rate, and there will be a lot of room for growth in the future, so it is used to refine the beast spirit, which really makes Yun Tian a little reluctant.

So in the face of these two situations, how should Yuntian choose?
