Outside the sky, the gap between the two worlds, the residence of Tongyou Academy.

Five days ago, under the response of Kou Chongxue and Ji Wenlong, most of the people on Tongyoulu Island were evacuated.

Except for the two or three hundred martial artists who had cultivated to the third order and below, who were directly sent to the Tongyin Xuan Realm by the two, most of the remaining fourth-order martial artists also returned to the academy after staying in the Heavenly Vault for a day or two.

At this time, there were only four people left in the Outer Heaven Dome, Kou Chongxue, Shang Bo, Yun Jing, and Shang Xia, and even Ji Wenlong personally returned to Tongyou Academy to sit down.

With the acceleration of the integration of the two worlds of Cangyu and Cangling, the boundary barriers between the two worlds have become weaker and weaker, and the difficulty of entering and exiting each other in many places has become lower and lower.

Previously, Tongyou Academy single-handedly led the rebellion of the Yan clan in the Cangling Realm, and most of the martial artists of the Yan clan, under the leadership of Yan Ming, a fourth-order master, infiltrated the battle domain of the two realms in batches without a trace, and cooperated with the Tongyou Academy to launch a surprise attack under the condition that the other three major tribes stationed and the martial artists of the Changbai Holy Land were completely defenseless, and captured more than 100 warriors from the fourth order to the martial extreme realm in one fell swoop.

Originally, after Tongyou Academy counterattacked the Two Realms Domain, although it had gained a firm foothold in Zawangpo, its sphere of influence barely accounted for one-third of the entire Two Realms Domain.

However, after this battle, the sphere of influence of Tongyou Academy has returned to its original range, and there are even faint signs of countering the Cangling Martial Artist.

After that, Tongyou Academy took these more than 100 martial artists as the basis, and under the witness of the fifth-order ancestors of both sides, an agreement was reached to exchange the lives of these people for the entire Yan clan to enter Youzhou.

And after most of the Yan clan's clansmen entered the Youzhou Territory through the Two Realms Battle Domain, and the more than 100 warriors were also released, the three major clans and the warriors of the Changbai Holy Land who were unwilling to suffer losses launched a crazy revenge in the Two Realms War Domain.

And the side of Tongyou Academy was naturally not to be outdone, the martial artists below the fourth order on both sides fought in the two realms of war, and now almost the entire warfield of the two realms has become a battlefield for both sides.

Although Tongyou Academy took a big advantage at the beginning, when it comes to accumulation and heritage, it is still inferior to the Changbai Holy Land plus the three major clans.

Even if the martial artists of the Yan clan joined in later, in the overall confrontation between the two realms, the side of Tongyou Academy gradually began to be inferior.

This is also one of the reasons why after the return of Tongyou Land Island, Kou Chongxue took everyone back to Tongyou Academy despite everyone's fatigue, and even let Ji Wenlong personally sit in Tongyou City.

In the past five days, Shang Xia spent most of his energy in the Outer Heaven Dome on figuring out the advanced formula of the Five Heavens deduced from the Four Square Monuments.

The remaining part of the energy was used to continue to consolidate his own cultivation, as well as the gains and losses in the process of this trip to the Barbarian Continent, and to sort out the gains during the period.

After completing this, Shang Xia's attention turned back to the Five Heavens Advanced Formula deduced from the Four Square Tablets.

Above the stele, columns of handwriting are from top to bottom, all over the four sides of the stele.

After Shang Xia's finishing, the content of the advanced formula completed is as follows:

Five Elements Realm Advanced Formula:

Name of the potion: Five Elements Shun Reverse Yin and Yang Ointment

Prerequisite: The Great Perfection of the Four Elephant Realms

Jun Medicine: The essence of the five elements of Yuangang (Jiayimu, Bingdinghuo, Wujitu, Gengxin Jin, and Nondecane Water) is divided into two parts: Yin and Yang

Adjuvant: One for the fourth-order metal, wood, water, fire, and earth spirits

The origin of heaven and earth can accelerate the process of advancement

It can also be refined, corresponding to the heaven and earth Yuangang, to save the cultivation process

Success rate: 60%~99%

Fit: 100%

Without any surprise, the Sifang Monument directly named the Five Heavens as the Five Elements Realm.

But when Shang Xia first saw this advanced formula, his first reaction was that he was a little dizzy.

Not to mention the others, just looking at the Five Elements Yuangang Essence required for the first medicine, there were not only five kinds of the Five Elements, but actually ten kinds, which made him feel very difficult to understand.

Shang Xia's cognition of the five elements is basically in the range of metal, wood, water, fire, and earth, and then extends outward, at best, he understands that the five organs of the human body belong to the five elements, the heart belongs to fire, the lungs belong to gold, the spleen belongs to earth, the liver belongs to wood, and the kidneys belong to water.

If he wants to extend something outward, he will be blind.

It is the Yuangang essence listed in the first item of the formula that belongs to the five elements, and the number is as many as ten kinds, and he was thinking about it for a long time before he suddenly woke up: the five elements also seem to be divided into yin and yang.

The essence of Yuangang of the five elements belongs to gold, and there are both yang Gengjin and yin Xinjin.

In the same way, wood lines can also be divided into the yang Jiamu Yuangang essence, and the yin Yimu Yuangang essence.

Further down, the essence of nonshui yuangang is yang, so the essence of decanshui yuangang is naturally yin.

The essence of Binghuo Yuangang is yang, and the essence of Dinghuo Yuangang is yin.

The essence of Wutu Yuangang is yang, and the essence of Yuangang is yin.

As for how to attribute the essence of Yuangang in one of the five elements to the yang genus or to the yin genus, Shang Xia will be blind again.

That is to say, just in the first item, if you want to get together ten different Yuangang essences, I am afraid it will be a difficult thing for people to scratch their scalps, not to mention that while dividing these Yuangang essences into the five elements, it is still necessary to distinguish yin and yang.

As for the five elements spiritual objects required for the medicine and adjuvants, although only a general range is given, there is no detailed designation, and there is no regulation on the quantity or quality of the changes, but the five kinds of five elements spiritual items required by the medicine must reach the fifth order, and the adjuvants also need to reach the fourth order!

You must know that fifth-order spiritual objects can often be used as forging materials for divine weapons.

Even if it is a fourth-order spiritual object, it takes a lot of effort to find it.

Just looking at the four fourth-order spiritual objects that represented the four seasons that Shang Xia needed when he advanced to the Four Elephant Realm, he could roughly measure the difficulty.

As for the Five Elements Jade required for the final medicine, according to the consistent law of the Four Square Tablets to deduce the advanced formula, this thing must be a fifth-order spiritual object, and it must be an extremely rare and rare thing among the fifth-order spiritual objects.

Shang Xia didn't know anything about the Five Elements Jade.

Fortunately, the Sifang Monument still gives a brief introduction to the five elements of jade, "containing the essence of the five elements in one", as the name suggests, probably refers to a piece of jade that can show the characteristics of the five elements of gold, wood, water, fire and earth.

And the remarks column given by the Sifang Monument is even more interesting.

From the content understanding, according to this advanced formula "Five Elements Shun Reverse Yin and Yang Ointment", there is more than one advanced elixir, but it should be two parts of yin and yang.

A piece of yin ointment should be based on the five essences of Yuangang, Xinjin, Yimu, De Shui, Ding Huo, and Ji Tu, and use it in the internal organs after being made into medicines.

The other yang ointment is based on the five essences of Yuangang, including heptyl gold, jiamu, nonshui, propylene fire, and pento, and the medicine made is used to apply the five internal organs on the corresponding parts of the body surface.

Moreover, when taking advanced medicines, it is best to do it in a place where the origin of heaven and earth is abundant, so as to speed up the absorption of the medicine, thereby shortening the time for advancement and avoiding accidents.

In addition, it was Shang Xia who was most satisfied with this complex set of fifth-order advanced formulas deduced by the Four Square Monuments, that is, even if he didn't refine the complete Heaven and Earth Yuangang, he could still advance to the Five Elements Realm!

Because Shang Xia could completely cultivate a complete Heaven and Earth Yuangang in the Dantian Origin after taking this advanced elixir!

Of course, you don't need to think about Shang Xia to know that relying solely on your own origin to cultivate the Heaven and Earth Yuangang will inevitably be a long and painful process.

Therefore, after advancing to the Five Elements Realm, Shang Xia could also shorten or directly complete this process with the help of refining the corresponding Yuangang essence, or the complete Heaven and Earth Yuangang.

In this way, it is not difficult to see that the advanced formula deduced by the Sifang Monument this time is much more complex than the other fifth-order advanced formula.

However, because there is no need to refine the Heaven and Earth Yuan Gang to be able to advance to the Fifth Heaven, and it is always much easier to find the Yuan Gang essence than to find a complete Heaven and Earth Yuan Gang, plus the success rate of this potion to advance to the Fifth Heaven is extremely high, therefore, it actually lowers the threshold for the advancement of the Five Heavens.

Of course, because there was no need to refine the complete Heaven and Earth Yuan Gang, Shang Xia could almost imagine that after advancing to the Fifth Heaven with this kind of advanced elixir, he would definitely be the weakest fifth-order martial artist in history.

But if you look at the ten Five Elements Yuangang Essences used in the advanced formula's Jun Medicine, and each Yuangang Essence will eventually be cultivated into a complete Heaven and Earth Yuangang, then its upper limit seems to be so high that everyone will smack their tongues.

According to the understanding of the five heavens in the Cangyu and Cangling worlds, martial artists need to refine the five realms of heaven and earth in this realm in order to reach the fifth-order perfection, and even get a glimpse of the realm of the five-fold heavens Great Perfection, and then hope to step on the threshold of the sixfold heavens.

And Shang Xia finally needs to refine the Ten Paths and Five Elements Yuan Gang as the natal Yuan Gang, and you don't have to think about it to guess how high Shang Xia's final strength will be.

All in all, what the Sifang Monument deduced this time was an advanced potion recipe with an extremely low sink and a high ceiling above the sky.

As for the estimation of the success rate given by the Sifang Monument, there is a gap of nearly thirty percent between the upper and lower limits, Shang Xia once tried to take away the Yang Five Elements Yuangang Essence or the Yin Five Elements Yuangang Essence alone, that is, assuming that Shang Xia only took one of the ointments, the Sifang Tablet actually gave a success rate of about eighty percent.

However, when Shang Xia made a separate paste of the essence of the Five Elements Yuangang, which did not distinguish between yin and yang, the success rate given by the Sifang Monument really plummeted to 60%!

This result really made Shang Xia smack, but the reason for smacking his tongue was not that the success rate was too low, but that it could be so high!

However, this allowed Shang Xia to rest assured that he would leave these castrated versions of advanced recipes to the family or Tongyou Academy.

It's not that Shang Xia cherishes himself and doesn't want to show people the advanced formula that fits him completely.

Instead, the complete advanced formula can only be used by him alone, with the assistance of the Four Square Monuments.

Unless other people also have a quadrangle monument on their bodies, Shang Xia is harming others if he makes his advancement method public.
