Styx got up, left the meditation room of cultivation, and walked out of the small courtyard, and walked towards the location of the library building of the Yunling Academy, and entered the Yunling Academy for a few months, Styx has been busy recovering his strength, and now it is the first time he has really walked in the academy, everything in this academy is unfamiliar to him, even the library building he is fascinated by is just a point on the map to him.

Speaking of which, although Styx has become the third-grade refining teacher of Yunling Academy, he has never fulfilled his duties, although he can get 110,000 contribution points every thousand years (I wrote it wrong before, every year is too short), but it is also an obligation, in this thousand years, Styx needs to refine at least three high-grade innate treasures for the academy.

This is nothing to Styx, after all, he is also a person who has already begun refining the Chaos Spirit Treasure, at least it is equivalent to the fifth-grade refining teacher in the academy, refining three top-grade innate treasures in a thousand years is not a problem, and it is also when the academy prepares the refining materials, so there is no need for Styx to bother.

And in addition to the obligation of three high-grade innate treasures every thousand years, Styx is completely free, even if it does not guide the academy students to refine weapons, the academy will not care, of course, this guidance of students to refine weapons is also a way to earn contribution points, but Styx is not interested in this at all, after all, it is too slow to earn contribution points in this way.

The contribution value required by the River Styx is really a large number, and if he wants to earn the contribution value as soon as possible, there are only two ways in front of him, one is to go to the mission hall to receive the task, complete the task, and naturally get a lot of contribution value, and the other is to sell the innate treasure, as long as the River Styx can refine a large number of innate treasures, and then sell them to the academy or students, he can naturally get a lot of contribution points.

Among these two paths, Styx is more inclined to the second one, it is too troublesome to do tasks to earn contribution points, it is not as easy as refining the innate treasure, in this battlefield of gods and demons, almost everyone has the innate spirit treasure, and the innate treasure is a valuable thing, as for the semi-chaotic spirit treasure or the chaos spirit treasure, it is even rarer, even in the academy, there are not many.

Styx joined the Yunling Academy at the beginning, out of habit, so he had reservations when refining the weapon, so he only refined the top-grade innate treasure, and became a third-grade refining teacher, and now if he rashly refines the best innate treasure or semi-chaotic spirit treasure, it will definitely arouse suspicion, so at present, Styx can only refine some high-grade innate treasures in exchange for contribution points.

According to the records in the identity token, this top-grade innate treasure can be exchanged for at least 50,000 contribution points, and if it is powerful, it can be more, Styx received the salary of 110,000 contribution points for the academy, but created at least 150,000 contribution points for the academy, which seems to be a bit of a loss, but in fact it is not.

On the one hand, Styx enjoys the excellent cultivation environment of Yunling Academy, and secondly, the refining materials required for the three top-grade innate treasures are all provided by the academy, and the refining materials provided can not only refine the three top-grade innate treasures, after all, there is always a time when they miss, if one accidentally only refines the middle-grade innate treasure, then it must not be refined.

And if Styx wants to sell the Innate Treasure to earn contribution points, he naturally needs to prepare materials by himself, and the contribution value in exchange for refining materials is probably not a small amount, and the contribution value he really earns is naturally far less than 150,000, it may be 120,000, or 100,000, it depends on how powerful Styx's refining methods are.

Thinking of this, Styx showed a smile on his face, he is still very confident in this refining method, not to mention that he also has a secret weapon, and the refining weapon is even more handy, but now, Styx has no time to think about this, because the library building has arrived, the towering high-rise building, the spirit is compelling, the brilliance in the building is circulating, and the guardian array is even more hidden in it.

At the entrance of the library building, there are no guards, only people who enter and exit the academy, and there are eight teleportation formations arranged at this door, corresponding to eight floors, and the identity token records the cultivation of this holder, just like the Styx has a half-step cultivation of the creation realm, at most he can only enter the seventh floor of this library building, of course, from this to the sixth floor, he can also enter.

For the first to sixth floors, Styx has no interest, because the first six floors have, the seventh floor has, after all, this library building is for everyone in the Yunling Academy, if it is a student of Da Luo Jinxian cultivation, he can only enter the first layer and exchange a contribution point for an exercise, and when he breaks through to the quasi-saint cultivation, he can exchange it for subsequent exercises in the second layer, so the collection of books on the first layer is available on the second floor, and so on, the seventh layer naturally has all the books on the first six floors.

In this case, how could the first six layers be of interest to the Styx, the Styx naturally walked directly to the teleportation array that teleported to the seventh layer, and if you want to enter the seventh floor of the library building, you need at least a half-step of cultivation in the Creation Realm, in this academy, there are many masters in the Daluo Realm, but there are not many people in this half-step Creation Realm, and I am afraid that there are less than a hundred people in total.

After entering the seventh floor of the library building, the Styx River looked at it, and there was no one in this layer, thinking about it, there are not many people in the half-step creation realm in the academy, and it is normal to meet no one on this seventh floor, after all, there is no time for cultivation, and a retreat may be thousands of years, not to mention that it is a master of the half-step creation realm, and it is also normal to retreat and comprehend the creation realm.

Styx carefully observed the seventh layer, and there were countless jade slips placed in these countless bookshelves, which recorded these various exercises, formations, and other cheats, and also divided the corresponding areas to place these jade slips, and there was a ban on this bookshelf, and each jade slip had a corresponding introduction in front of it, and only by paying the corresponding contribution value could you get the things recorded in the jade slips.

There is no one guarding this seventh layer, but Styx has no intention of robbing it, not to mention that the prohibition on this bookshelf is connected to the large array in this library, but even the four statues placed in this layer are not so easy to mess with, Styx knows about the puppets and has some research, so he can naturally see at a glance that these four statues are all puppets with the strength of the half-step Creation Realm.

Once the ban is touched, not only will the large array of this library be activated, but these four puppets will probably also be activated, and then it will alarm the strong people of the Creation Realm in the academy, it will really be difficult to escape, so the academy naturally did not send people to guard this library building, not because of arrogance, it is really not necessary, if there are really strong people who are not afraid of these, even if they send people to guard here, it will have no effect.

Styx looked at these countless jade slips, and naturally felt a little itchy in his heart, and he wanted to keep them all for himself, but with his current strength, there was no need to think about robbing, or honestly spend contribution points to see these jade slips, the first thing Styx wanted to see was naturally the record of this god and demon battlefield, and the jade slips of this kind of record were also the least in this layer, and it didn't cost much contribution value.

With only a thousand contribution points, Styx got all the information about the battlefield of gods and demons recorded in this layer, including all the creatures in the battlefield of gods and demons, treasures of heaven and earth, forbidden land, treasure land, and so on, which benefited Styx a lot, but there was one of them, which made Styx a little surprised, far more shocked than when he learned that the flood was not the only one.

This chaos seems to be endless, there is no boundary, but in fact there is, but few people have seen it, and according to the records in this jade slip, this chaos is not the only one, strictly speaking, there are four chaos, namely the east, south, west, and north four desolate chaos, and the chaos where the Styx is located is the Eastern Desolate Chaos.

In these other three desolate chaos, there is also a Chaos Demon God as powerful as the Pangu God, and the Pangu God, each level of the Yuan plays the same identity and does the same thing, and every time the sky is opened, three thousand worlds will be born in the Four Desolations and Chaos, all of which are incarnated by the corpse of the Sanqing Chaos Demon God, so it is the real heavens and ten thousand worlds that enter the battlefield of gods and demons this time.

This god and demon battlefield is in the center of the four desolate chaos, connected to the four desolate chaos, in each level of the element, when the four desolate chaos develops to meet certain conditions, the god and demon battlefield will be opened, the four desolate chaos, the chaos of the heavens and all worlds will enter it, as for what the specific conditions, no one knows until now.

Of course, after entering the battlefield of gods and demons, the people of the four desolations and chaos, the heavens and all the worlds will appear in the lower level of the gods and demons battlefield, and in the lower layer, the people of the four desolations and chaos cannot meet, only after entering the middle layer, the people of the four desolations and chaos can be regarded as really in the same world, it can be said that the lower world of the gods and demons battlefield is a buffer zone, and it can be regarded as a kind of protection of the avenue for each era of 'newcomers'.

And in the middle of this god and demon battlefield, it is mainly divided into five regions, namely the Eastern Domain, the Western Domain, the Southern Domain, the Northern Region and the Middle Domain, the four domains of the southeast, northwest and northwest correspond to the four desolate chaos of the southeast and northwest respectively, and the Styx River is now located in the Eastern Domain, and this middle domain is the center of the middle level of the god and demon battlefield, where the concentration of heaven and earth aura and law qi is much higher than that of the four domains.

And the middle domain is also the place where the four desolations and chaos are truly fused, and the complexity can be imagined, although there are countless opportunities in it, but it is also much more dangerous than the four domains, if you are not careful, you may die without a place to be buried, there, the half-step creation realm is no longer a master, even if it is a master of the half-step boundless realm, I am afraid there are a lot.

Thinking of this, Styx couldn't help but gasp, he could fully imagine what kind of place the middle domain of the four desolations and chaos converged, and for the intention of the avenue, Styx also had a little guess, the gods and demons battlefield had countless opportunities, and cultivated countless strong people, and in each level of the element, the four desolations and chaos, the chaos of the heavens and all the worlds gathered among them, killing for the sake of opportunity, killing for survival, and even killing for the sake of killing, there is only endless killing here, and the name of the battlefield of gods and demons is well deserved.

And everything in this god and demon battlefield is just like the avenue raising Gu, using the temptation of endless opportunities in the god and demon battlefield to bring together the mixed yuan powerhouses in each era, so that they can continue to grow in the killing, and finally become the strongest, this is no different from raising Gu, thinking of this, Styx's expression couldn't help but become solemn, the avenue raises Gu, and what is the 'Gu' raised for?
