Thinking of this, Styx's mood also became a little heavy, the strength and mystery of the avenue, with the current strength of Styx, it is impossible to face it, even if you know more, it is just to increase your troubles, throw away the thousands of thoughts in your heart, Styx now has only one thought left in his heart, that is, to become stronger, only strong strength can make him fearless of everything.

After reading all the records of the battlefield of gods and demons, Styx turned to the two areas of formation and refining, as for the exercises, supernatural powers, and so on, the books are basically useless to the Styx, the Styx has its own way, what is the use of these exercises and magical powers, only the jade slips of the two ways of formation and refining are of some use to the Styx.

However, there are hundreds of ways of refining weapons, and the formations are even more thousands, after countless years of accumulation, there are too many jade slips about the two ways of the instrument array in this library, and there are too many that make it a little difficult for Styx to choose, don't look at the contribution value of one hundred and nine thousand now, but if you want to exchange them all, it is still far from enough.

Therefore, Styx can only purposefully choose some jade slips, the way of refining, Styx is very good at it, but the method of refining the Chaos Spirit Treasure is deduced by the Styx itself, although there is no big mistake, but it is insufficient, so the Styx spent 60,000 contribution points to exchange for a jade slip that records the refining of the Chaos Spirit Treasure, which records in detail the method of refining the Chaos Spirit Treasure and various chaos prohibitions.

After reading the method of refining weapons recorded in the jade slip, Styx can also be regarded as an eye-opener, although he has begun to refine the Chaos Spirit Treasure, and will also arrange the Chaos Prohibition, but now it seems that there are still a lot of defects, and now that he has obtained this detailed method of refining the Chaos Spirit Treasure, the Styx can use it to confirm each other with his own refining method, learn from each other's strengths, and make himself a step further in refining weapons.

As for the formation, there are too many jade slips stored on the bookshelf on the seventh floor of this library building, Styx took a cursory look, there are not ten thousand, there are eight thousand, killing arrays, trapped formations, maze formations, combination formations, etc., it can be said that there are everything, it can be seen that Styx is itchy, among the three ways of the Dan Weapon Array, the Styx prefers two instrument arrays, and now that so many formations are placed in front of him, how can he not be moved.

Previously, he wanted to improve the four great formations of the Flood Desolation, not because he was conservative, but because he was most familiar with these four formations, and knew the mysteries of them, if he could improve the four great formations of the Flood Desolation successfully, he could have time left for the Styx, after all, if he started from scratch to comprehend a new formation, the time he turned into would definitely be much less.

But if you really encounter a suitable formation that can replace the four great formations of the flood and desolation, the river Styx will not be conservative, and it will be abandoned when it is time to abandon it, although the river Styx has a lot of feelings for the four great formations of the flood and desolation, but on the way to pursue the supreme avenue, the river will not be emotional, rather than let them become a burden, it is better to let them become memories.

However, although there are many formations here, there are very few that are really powerful, especially the formations that can exert the power of the Creation Realm are even few, I am afraid that most of the formations with the power of the Creation Realm are hidden in the eighth layer, but unfortunately, the Styx River cannot go up for the time being, unless he can break through to the Creation Realm as soon as possible.

But for the sake of the formation, you have to disrupt your own rhythm and plan, Styx is obviously impossible to do this, there are several formations here that have the power of the Creation Realm, although they are not the type that Styx wants, but Styx has not given up, the way of formation, there is no strongest, only the most suitable formation, just like this twelve heavenly gods and gods, although it is strong, it is only suitable for the twelve ancestors, in the hands of Styx, but it is not one out of ten.

Since the formation of the power of the Creation Realm is not attractive to the River Styx, then the River Styx retreats to the second, there are thousands of ways here, and the River Styx can always find what he wants, but he has only picked out two formations, which add up to 45,000 contribution points, although there are still some formations that are useful to the River Styx, but he really has no contribution points to exchange.

The two formations selected by the River Styx, one is the sword array, called the 'Yin and Yang to one sword array', this sword array only needs two long swords and a formation map, but these two swords are not without requirements, the sword is divided into yin and yang, yin and yang are one, then the power of the sword array can be exerted to the extreme, yin and yang a sword out, then the heaven and earth are divided, but this sword array is a remnant array, so it can only exert the power of the half-step creation realm, if it is a complete sword array, I am afraid it will be able to exert the power of the creation realm, worth 20,000 contribution points.

This set of sword arrays, Styx intends to hand over to the Red Lotus Dao people, the Red Lotus Dao people hold the two swords of Yuan Tu A Nose, although these two swords are pure killing, there is no difference between yin and yang, but the Red Lotus Dao people understand the Zhuxian Sword Formation, and they are naturally extremely proficient in the sword array.

As for the other formation, it is a star formation, but the Zhou Tian Xingchen comprehended by this array is the Zhou Tian Xingchen of this god and demon battlefield, the mystery is abnormal, far from being comparable to the Zhou Tian Xingchen Array of the River Styx, this array contains some mysteries of the Zhou Tian Xingchen of the God and Demon Battlefield, if the Qiankun Dao people comprehend the mysteries, it will not be a problem to improve the Zhou Tian Xingchen Array at that time.

Moreover, since the predecessors were able to comprehend the Zhou Tian Xingchen in the battlefield of gods and demons, then the Qiankun Dao people can also do the same, speaking of which, the Zhou Tian Xingchen in this battlefield of gods and demons is weird, although the naked eye can see it, but it is impossible to find out their true face, even where these Zhou Tian Xingchen are, it is also traceless, it is indeed a little weird.

With these two formations, the Qiankun Daoist and the Red Lotus Dao people have the hope of improving the formation, as for the Styx and Mu Sen, they are not in a hurry, especially Mu Sen, this mixed yuan true martial arts formation is their enlightenment from the word 'Wu', since they want to improve politics and law, Mu Sen began to comprehend the word 'Wu' again, hoping to find inspiration for improving the formation.

As for the Twelve Heavenly Gods Great Array, Styx has no idea about it, this formation is huge, but Styx can't fully exert its power, the fault is not in the formation, but in the people, since there is no clue, Styx simply put it temporarily, after all, compared to the three corpses, Styx's strength is the strongest, even if it is separated from the three corpses in the future, no formation is enough to protect itself.

Leaving the library building, Styx did not return directly to his small courtyard, but went directly to the mission hall, although the task as a three-grade refining teacher was to refine three high-grade innate treasures in the previous year, and there is still plenty of time now, but Styx does not plan to drag it all the time, and he also needs to refine some innate treasures in exchange for contribution points, otherwise where will the resources supply him and the transformation of the three corpse magic weapons and the advancement of the Qiankun world.

After entering the mission hall, this place is like a small world, very vast, there are too many people in and out, not only because this is the place to receive tasks, but because the place to exchange various resources is also here, so this is naturally the most lively place in Yunling Academy, there is no one.

Styx didn't look much at it, and came directly to the place where he completed the teacher's task, after checking the identity token, Styx got a bunch of refining materials, looking at the quantity, it was enough for him to refine almost five top-grade innate treasures, but the requirements of the academy only needed to refine three top-grade innate treasures, so that Styx earned two top-grade innate treasures for nothing.

In fact, if it were replaced by other third-grade refining teachers, they would not think like Styx, after all, not every third-grade refining teacher can guarantee that they are top-grade innate treasures every time they refine them, after all, they always have times when they miss, and they can't be 100% refined like Styx.

After entering the refining workshop prepared by the mission hall, Styx directly summoned the Qiankun Ding and the three corpses, and the four of them worked together to refine the innate treasure, so that a lot of time could be saved, and they could also refine their refining techniques by refining these top-grade innate treasures, although they could not refine the best innate treasures and half-step chaos spirit treasures for the time being, but they could also make their refining techniques more refined and subtle.

Of course, the River Styx and the three corpses also have their own reservations, and the way of refining weapons created by the River Styx, among which the power of the law is the best effect, but the River Styx and the three corpses combined, but there are seven kinds of laws, the law of blood, the law of soul, the law of Qiankun, the law of space, the law of cause and effect, the law of killing and the law of martial arts.

In order to save time, Styx let the three corpses come out to help refine the innate treasure together, if others can see the clues on the innate treasure they refined, it will not be in vain to arouse the suspicion of others, so Styx naturally has to keep a hand, the innate treasure refined by the three corpses completely depends on the refining materials, the innate treasure and the refining technique, and will not be contaminated with any of the laws that the three corpses have, and the three of them refined the three high-grade innate treasures that Styx used to deal with the Yunling Academy.
