This time, Tong Li's injury was not light, after Sun Hao stabilized his internal injury, he no longer helped, but let him cultivate his own ten thousand grinding strength, this time the injury was serious enough, especially a burn, with a lot of area, it is estimated that Tong Li will grind for a while.

And Sun Hao, after settling down Tong Li, he must also comb his body, there are many injuries on his body, although they are all fine, but it is estimated that he still has to cultivate for a day or two, and if he refines his qi cultivation to enter the fifth layer, he also has to have a few days to consolidate his cultivation.

So, Sun Hao also began to rest in the temporary cave mansion.

The Fire Frog Swamp was rare for a few days of calm.

After Sun Hao's injuries healed, his cultivation had stabilized to the fifth layer of qi refining, and with the improvement of cultivation, the strength of various spells increased, if it was said that Sun Hao used to mainly kill the eighth-layer fire frogs of qi refining, then, after upgrading to the fifth layer of qi refining, Sun Hao aimed at those fire frogs who had just entered the ninth layer of qi refining.

That golden-threaded fire frog king, Sun Hao still can't help it at the moment, and naturally he won't mess with it.

Sun Hao once again entered the Fire Frog Swamp, and the swamp became lively again.

This time, Sun Hao no longer dodged, and generously looked for the fire frog in the early stage of the ninth layer of qi refining to kill. At the beginning, the Golden Thread Fire Frog King would always run to retaliate in a hurry after Sun Hao killed the Fire Frog.

However, although Sun Hao can't help it, it doesn't seem to be able to help Sun Hao, every time it chases after Sun Hao's buttocks, every time it is a little bit closer, and it is helpless against Sun Hao. Moreover, after chasing for a long time, the Golden Thread Fire Frog King found that he seemed to have become Sun Hao's sparring partner.

Indeed, the Golden Thread Fire Frog King has become Sun Hao's excellent sparring partner, fighting against the Golden Thread Fire Frog King, Sun Hao can practice the Flying Grass Technique, after a few battles, Sun Hao's proficiency in performing the Flying Grass Technique has increased significantly, and under the full operation of Mu Dan, the high concentration of wood aura formed after the Frog King inhales every day is of great benefit to Sun Hao's cultivation.

And Tong Li, after half a month of grinding his injuries, the effect is also quite amazing, he has already entered the middle stage of the fourth layer of qi refining, and he is only one step away from entering the late stage of the fourth layer of qi refining.

found that he had become Sun Hao's sparring partner, and the Golden Thread Fire Frog King, who was not stupid, quit and began to strike.

No matter how loud Sun Hao killed the fire frog, the fire frog boss only chirped a few times in the nest to show his savings, and he would never come out to take revenge on Sun Hao casually.

Without the sparring partner of the Golden Thread Fire Frog King, Sun Hao's cultivation direction has also changed.

With the Golden Thread Fire Frog King, he practiced the Flying Grass Technique and the Ten Thousand Wheel Grasshopper Grasshopper, and without the harassment of the Golden Thread Fire Frog King, Sun Hao once again focused on the formation layout and talisman refining.

At present, Sun Hao has been able to quickly lay out the second-level basic formation, after a period of practice, after laying out most of the second-level basic formations, Sun Hao is ready to lay the first-level formation, once the first-level formation is successfully deployed, then Sun Hao will become a first-level formation mage.

Different from the formation arrangement, with Sun Hao's success in refining several runes such as green wood wrapping and convex wooden stakes, Sun Hao has actually become a first-class rune seal, and Sun Hao has refined a high-grade rune seal, and he is also a leader among the first-level rune seals.

Among the few spells that Sun Hao has mastered at present, only the Flying Grass Technique, the most practical spell has not yet been refined into a rune seal. In the past, because of insufficient spiritual power, Sun Hao did not have enough spiritual power to support him, and he could not refine the Flying Grass Talisman Seal. Now that his cultivation has improved and he has reached the fifth level of qi refining, Sun Hao feels that he can try refining the Flying Grass Talisman.

Concentrate your mind, sit cross-legged, adjust your breathing, and reach a new high point in your spirit, which is different from refining other talismans, because the Flying Grass Technique must be in the rhythmic state that Sun Hao said can only be cast, so after Sun Hao stood up, the Pure Heart Technique and the Five Elements Wheel Spirit Technique began to operate, entering the pre-state of casting the Flying Grass Technique, and then began to draw talismans.

Compared with the previous spells, the runes of the Flying Grass Technique were much more complicated, but with the foundation of refining the runes such as Aoki Entanglement and Convex Wood Stakes, Sun Hao still perfectly refined his first Flying Grass Rune Seal under the condition that the true qi could guarantee.

After refining the talisman seal, Sun Hao found that almost two-thirds of the true qi in his body had been used, and refining this talisman seal would consume more true qi than Sun Hao's own flying grass technique.

After meditating for a while, with the help of Mu Dan, Sun Hao quickly replied, and after about two pillars of incense, Sun Hao opened his eyes and observed the flying grass talisman in front of him. This talisman seal is well refined, and the accuracy between the runes has reached the top grade of the Aoki winding talisman seal.

Full of confidence in the grade of the seal.

Sun Hao suddenly discovered that this good-looking flying grass talisman seal was actually only a low-grade Cheng dù who was close to the middle grade, and there was still a big gap between it and the upper grade.

Not believing in evil, Sun Hao once again refined a flying grass talisman seal.

In the second refining, the effect of this rune seal is better than the first one, and the accuracy has increased greatly, but it has only reached the level of the middle-grade rune seal, and there is still a big gap from the top grade.

Refining several Flying Grass Techniques in a row is the same result.

So what is the reason for this?

After thinking about it, Sun Hao felt that the reason for this situation was probably the fault tolerance rate of runes.

The so-called fault tolerance rate, simply put, is similar to the standard rune, different runes have different requirements, it is said that the green wood winding, it is estimated that as long as it reaches 80% of the similarity with the standard rune, it can be refined, and the fault tolerance rate of the green wood is 80%.

But with the increase of the spell level, this fault tolerance rate is estimated to be also improving, the level of the first three spells is not much different, this fault tolerance rate difference is relatively small, did not attract Sun Hao's attention, however, the error tolerance rate of the Flying Grass Technique is at least eighty-five percent or more, that is to say, the runes of the Flying Grass Rune Seal must reach more than eighty-five percent of the standard runes to refine the top grade.

The error tolerance rate is the same as that of Aoki's wrapping of the high-grade talisman, and it can only refine the medium-grade flying grass technique.

Among the massive books that Sun Hao has read, there are some records of refining talismans, and there are also records that the higher the level of spells, the more difficult it is to refine talismans, but why is it more difficult, but he rarely cultivates to get to the bottom of it.

However, Sun Hao feels that to find a problem, it is necessary to find the root cause of the problem, so that it can be strengthened and solved in a targeted manner to achieve the goal of truly solving the problem.

Assuming that the fault tolerance rate really exists, then, what can be done to improve this fault tolerance rate?

That is, how can we make fewer mistakes?

Sun Hao listed some of the problems of refining the talisman seal one by one, and listed the shortcomings of his refining talisman seal one by one. Some time ago, because of the refining of three high-grade talismans, Sun Hao felt very good and relaxed himself, but this time, the refining of the flying grass technique gave him a head start and made him sober.

If he wants to refine the talisman seal well, Sun Hao has to continue to work hard.

After carefully analyzing his refining process, Sun Hao still found his shortcomings in different aspects.

For example, Sun Hao's calligraphy habits have not fully conformed to the specifications of runes, and must be revised and improved in long-term practice.

For example, the texture of the blank rune paper has a subtle effect on the writing runes, which is really not felt if it weren't for Sun Hao's long-term refining of blank rune paper. Although the blank rune paper refined by the fire frog skin has been processed by several procedures, the textures of its own growth still exist, and these textures will inevitably have a huge impact on the formation of runes.

This must also be overcome.

In the end, thinking about it, combined with the knowledge of the formation he cultivated, Sun Hao also felt that whether it was a rune or a formation, there was a similarity between the two, that is, the grasp of the angle, between the arrays, between the formations, and between the runes, which had a great impact on the success rate of forming a formation or refining a rune seal.

But what makes Sun Hao depressed is that so far, Sun Hao has not seen any books on this kind of angle size distinction, lacks a basic definition of angle, and the size of the good or bad is all based on experience.
