After discussing, Fang Huairan and Zhou Tong began to get busy, Fang Huairan mainly recovered his own lost essence and blood, and Zhou Tong devoted all his energy to studying the Yin Yang Xuanlong Pill.

Time flies, and in a blink of an eye, Fang Huairan and Zhou Tong have been stationed in the Purple Moon Palace for twenty-five years, and when the thirteenth duty mission was completed, the two of them refused the hunting invitation of Liu Yanbo and Meng Qingxian and other monks on duty at the same time, and teleported back to the ground.

Back on the ground, Fang Huairan and the others immediately paid a teleportation fee of one million spirit stones back and forth, so that the next time they went to the Purple Moon Palace, they would not have to pay.

Out of the teleportation hall, Fang Huairan and Zhou Tong identified the direction, and flew straight to the Tianbao Peak of the Tianji Gate, the two of them came back this time, and the main task was to collect the auxiliary refining materials of the Yin Yang Xuanlong Pill.

As for the main material of the Yin Yang Xuanlong Pill, the Yin Yang Ghost Dragon Spirit Core, the two of them have harvested ten over the years, which is enough for Zhou Tong to use in alchemy.

As for why there are only ten, it is because in the following years, there were not two harvests every year like the first year, but sometimes more and sometimes less, and finally there was no at all.

Fang Huairan and Zhou Tong analyzed and came to the conclusion that it may be like attracting demon beasts in the open sea, and the Yin Yang Ghost Dragon in an area has been drained, so even if there are Yin Yang Beads there as bait, there is no conclusion that the Yin Yang Ghost Dragon can be attracted.

After analyzing this result, the two immediately took back all the yin and yang beads that had been arranged before, and then after a year, they used the strange light source as the center of the sphere again, and chose a new 90-degree fan-shaped surface on the sphere to place the bait.

Although it took nearly three years from receiving and re-release, the effect was indeed immediate, and the two of them returned to the Purple Moon Palace to guard for less than half a year, and they felt that there was a formation that could not be broken, and judging from the order of the breakage, it must be a yin and yang ghost dragon.

At this time, Zhou Tong felt that he was completely sure of refining the Yin Yang Xuanlong Pill, and as soon as the two discussed, they decided to take advantage of the fact that the limelight of asking for the Danfang had passed, and returned to the ground to collect the auxiliary materials for alchemy.

The Tianbao Peak of the Tianji Gate was even bigger than the Tianbao Peak of the Tianji Pavilion, so after spending three days and two million spirit stones, the two of them finally collected thirty auxiliary materials for the Yin Yang Xuanlong Pill.

In this way, everything is ready, and only Zhou Tong's alchemy is owed.

Of course, according to Zhou Tong's research on the Yin Yang Xuanlong Dan Formula, it is impossible for the two of them to refine the Yin Yang Xuanlong Pill in the Purple Moon Palace, because at the moment of Dan Cheng, they need to absorb the surrounding heaven and earth aura, although this degree of absorption is very small, and it can't even be compared with the monk's advanced Dan, but it is indeed absorption.

Moreover, this absorption is different from the absorption of the foundation building advanced knot pill and the knot pill advanced yuan infant, it is more similar to the invocation of the aura of heaven and earth by the monks of the god transformation period, and the aura of the invocation is sealed into the pill using the power of the spiritual core of the yin and yang ghost dragon.

Because of this, this Dan can have a success rate of nearly one percent for the advanced transformation of the monks of the late Yuan Infant period, in addition to helping the monks to attract the aura of heaven and earth into the body, it can also pass on the experience of the aura to the late Yuan Infant monks to a certain extent.

Knowing that refining would not be successful due to location problems, the two still decided to collect all the materials, and Zhou Tong had to refine the materials at any cost.

The reason why this is done is because alchemy and refining are very different, for example, even if Fang Huairan has reached the top level of the refining master, as long as he does not enter the transformation god, he will never be able to reach the level of the refining grandmaster, because the process of refining the spirit treasure requires the monk to mobilize the spiritual energy of heaven and earth to open the spirit.

But for alchemy, there is no such requirement, even if there is a demand for heaven and earth aura, the pill will also absorb the heaven and earth aura by itself during the condensation process, without the intervention of alchemy monks.

Therefore, there are alchemy masters in the Yuan Infant stage, but there is never a Yuan Infant refining Grandmaster!

As for Tang Yucheng, the refining master who designed the refining plan for the two of them when they were in Tianji Pavilion, in Fang Huairan's opinion, the refining master was just an honorific title, or Tang Yucheng had refined a Lingbao-level puppet with the help of external forces.

After collecting the materials, the two lived in the Ningyang Palace for more than a month, and then took the ultra-long-distance teleportation array to go to Ziyue.

Because they sensed that the formation at the bait arranged by the two was broken, the two of them went to the weird place non-stop to collect the spirit core of the Yin Yang Ghost Dragon.

When the two of them came from the strange place, the one-year rest time was almost over, Fang Huairan cheered up and went to duty, while Zhou Tong practiced the refining of the Yin Yang Xuanlong Pill in the mirror of the world.

It is worth mentioning that in the past 20 years, Fang Huairan and Zhou Tong have won the ranking of the Yin Yang Xuanlong Dan, from the previous thirty-three and thirty-four, to thirty-three or thirty-one.

At this rate, the two of them had estimated that even if they were stupidly waiting for the turn of the number, two hundred years would be enough, and for the monks of the late Yuan Infant period, it was not impossible to wait.

It's no wonder that there has never been a shortage of monks stationed in the Purple Moon Palace, because for the new monks who are at the back, it is still very promising.

For the monks in the Purple Moon Palace, there is nothing else to refer to except for their own calculations, unlike on the ground, where the four seasons change year by year, and the passage of time is clear.

In the blink of an eye, another twenty-five years had passed since Fang Huairan and Zhou Tong returned to the ground halfway, and on this day, Fang Huairan and Zhou Tong came to Chen Mohan's ancestor's residence together after finishing their one-year duty mission.

The ban on the ancestor's residence was opened, and after Fang Huairan sacrificed a transmission note, he pulled Zhou Tong to wait quietly at the door.

It didn't take long for Chen Mohan to let the two in, and after learning that Fang Huairan and Zhou Tong had come to ask to return to the ground this time, Chen Mohan asked with a surprised face: "How many years have you been here, and what is your current ranking?"

Fang Huairan respectfully clenched his fists and replied, "Back to the Ancestor, it has been fifty years since I came to the Purple Moon Palace, and now my ranking has reached twenty-two or twenty-three. ”

According to the agreement of the three sects, whether you get the Yin Yang Xuanlong Pill to leave, or leave halfway by yourself, as long as you leave, the ranking will be automatically invalidated, and even if you come to guard again in the future, you will be ranked from the last place. Chen Mohan persuaded.

Fang Huairan and Zhou Tong glanced at each other, and Fang Huairan opened his mouth and replied: "The cultivation of the disciple and Tongtong has reached the Great Perfection of the late Yuan Infant stage, plus our spirit pet has also reached the peak of the late stage of the Yudan, so the two of us want to apply to return to Dongyang Star."

One is to let the spirit pet advance, and the other is that we ourselves want to try to see if we can succeed in advancing this time, if not, our age is just five hundred years old, we can apply to come to the Purple Moon Palace to garrison, and waiting for another hundred years is nothing. ”
