Although Ren Xiaoyao still had a lot of things to deal with outside, for Ren Xiaoyao, there was nothing more important than him refining the Nian Ding and the Ninety-Nine Gathering Spirit Array.

Now, whether it is Nian Ding or the Ninety-Nine Gathering Spirit Array, Ren Xiaoyao has already gathered the materials and can directly start refining.

However, with Ren Xiaoyao's current refining level, the success rate of refining these two treasures is not high. Also, if you fail, you don't know how long it will take to gather all the materials.

Therefore, at this time, Ren Xiaoyao, after thinking about it again and again, first gave up the refining of the Nine-Nine Gathering Spirit Array, and instead specialized in refining Nian Ding.

Before officially starting to refine Nian Ding, Ren Xiaoyao first took a Meditation Enlightenment Pill mixed with Ruoxi wine, and then took out a large amount of refining materials and began the crazy refining process. However, what is refined is not a magic weapon-level Nianding, but a magical-level Nianding.

According to the description of the spirit of the elixir, there seems to be some kind of master-slave relationship between the magic weapon-level nunding and the magic weapon-level ninding, that is, the more monks who use the magic weapon-level native, the more benefits the monks who use the magic weapon-level native.

Therefore, refining the magic weapon-level Nian Ding first, on the one hand, can make Ren Xiaoyao familiar with the refining method of the Nian Ding, and on the other hand, he can study the relationship between these two different levels of Nian Ding.

After more than a month of repeated refining, Ren Xiaoyao has refined a total of hundreds of magic weapon-level nindings, and has mastered the refining method of the magic weapon-level reading tripods extremely thoroughly. In the last dozen refining processes, Ren Xiaoyao even refined three top-notch Nianding magic weapons.

However, although Ren Xiaoyao was familiar with the refining method of the magic weapon level Nian Ding, he never discovered the secret of zài in this Nian Ding, at most he just felt that the refining method of this Nian Ding was different from the conventional refining method.

"It's time to refine the magic weapon-level Nian Ding. Ren Xiaoyao took a deep breath and took out a piece of valuable materials from the storage bag, including the Weeping Bloodstone that Ren Xiaoyao had just obtained, and the Quenching God Stone that he had obtained in the dungeon.

In this way, pieces of mineral materials were melted and refined in Ren Xiaoyao's hands, and then refined into semi-finished products, and finally refined into the finished product of the magic weapon.

At this time, more than a month has passed from Ren Xiaoyao's beginning to refine the magic weapon-level Nianding to the official completion of the magic weapon-level Nianding. It was the first time that a magic weapon had been refined for such a long time since Ren Yao's alchemy technique was completed.

It can be seen from this that the difficulty of refining Nianding is very difficult.

"I don't see anything surprising about this?" Ren Xiaoyao asked himself with a puzzled look as he held the magic weapon in his hand.

In Ren Xiaoyao's hands, there was a three-legged incense burner that had just been refined, and the surface texture was blurred and dull, and there was nothing outstanding to see. But it is a magic weapon, and it is still a magic weapon that the spirit of the elixir attaches great importance to.

Ren Xiaoyao repeatedly studied this newly refined magic weapon Nian Ding, but he didn't find any clues, and finally had to hold the attitude of trying it and recognized the magic weapon.

However, as soon as Nian Ding was recognized by Ren Yao, a strange change occurred. The originally vague texture gradually became clear and simple, and the surface aura was compelling, exuding a hazy brilliance.

What's even more amazing is that this Nian Ding was originally only the level of a low-grade magic weapon, but after Ren Yao recognized the master, he slowly absorbed an inexplicable power from heaven and earth, and the grade rose from a low-grade magic weapon to the level of a middle-grade magic weapon.

Moreover, in the dantian of Ren Yao, a soft white light was inexplicably added.

The white light that suddenly appeared in his body made Ren Xiaoyao frightened, and he hurriedly used the mana in his body to expel this white light. However, no matter how much Ren Xiaoyao operated the mana in his body, he couldn't expel the sudden increase in white light in the dantian. This white light is like not existing, except that it can be sensed by Ren Xiaoyao, it has no other effect.

Ren Yao ran his mana, carefully sensing the changes in Nian Ding, and after a few hours, he figured it out a little. It turned out that the soft white light in Ren Xiaoyao's body was absorbed by Tong Guò Nianding from heaven and earth.

"Could it be that this is the power of faith, which is sucked from those monks who use magic weapons or spiritual weapons?" Ren Xiaoyao guessed in his heart, feeling that this way was very strange.

However, there was more than one strange thing that happened to Ren Xiaoyao, and after Ren Xiaoyao was a little surprised, he was a little yearning.

After recognizing the master, after repeated contemplation of Nianding, Ren Xiaoyao also had a certain understanding of the characteristics of Nianding. For this peculiar alchemy furnace, Ren Xiaoyao also wanted to see how it helped alchemy.

So, after refining Nian Ding, Ren Xiaoyao performed the method of sacrificing the spirit in the spirit sealing recipe on him, and finally drove Nian Ding to refine an ordinary elixir.

What made Ren Xiaoyao extremely happy was that he originally thought it was just an ordinary high-grade elixir, but when it was finally baked, he got a semi-top-grade elixir.

Ren Xiaoyao was ecstatic in his heart, and he couldn't believe it, he refined a few furnaces of pills again, and the quality of the pills he got was still much better than expected.

In other words, this Nian Ding can make the refined elixir of higher quality.

With a hint of apprehension, Ren Xiaoyao took a few pills refined with Nian Ding and cultivated.

"These pills, there is no problem!" After finishing his cultivation, Ren Xiaoyao couldn't help but laugh with a happy look on his face.

With Nian Ding's help, Ren Xiaoyao's alchemy can directly rise to a level, and some pills that could not be refined can now be refined. And with the help of the more valuable elixir, Ren Yao's cultivation path will become easier.

Taking advantage of some time, after Ren Xiaoyao finished refining Nian Ding, he did not leave the customs, but took out a large amount of elixir from the storage bag and began the crazy alchemy process. In the dungeon before, in order to save his fellow human race, Ren Xiaoyao had almost consumed the precious pills he had taken on his body, and it was time to replenish some.

In the third month after the end of the dungeon, in the expectation of countless people, Ren Yao was released.

Outside Ren Xiaoyao's cave mansion, there were hundreds of transmission notes, some other monks wanted to get acquainted with Ren Xiaoyao, some wanted to join the Iron Blood Guard or the Easy Clan, and some asked Ren Xiaoyao to help with alchemy refiners, and so on. For these transmission notes, Ren Xiaoyao just hurriedly read them, and then directly forgot about them.

Ren Xiaoyao, who had just come out of the customs, came to the headquarters of Xiaoyao Treasure Pavilion for the first time and summoned all the branch shopkeepers over.

"This is a kind of alchemy furnace that I have newly developed, called Xiaoyao Ding, the Divider Level and the Spirit Weapon Level. Your branches must stock up all year round, and the method of refining can also be sold at a low price. Ren Xiaoyao took out more than a dozen magic weapon-level Nian Ding, and handed over more than a dozen Lingzhu slips to the other branch shopkeepers.

Although the shopkeepers were curious, when they heard the name Xiaoyaoding, they thought that Ren Xiaoyao just wanted to promote this treasure developed by himself, so they didn't care. They didn't know that Xiaoyao Ding was Nian Ding, and it was not developed by Ren Xiaoyao.

Since the magic weapon level and spirit weapon level Nian Ding are helpful for the growth of the Nian Ding in Ren Xiaoyao's hands, and it can also increase the white light in Ren Xiaoyao's body, Ren Xiaoyao naturally wants to vigorously promote Nian Ding. Moreover, since the Nian Ding in Ren Xiaoyao's hand is like a mother's body, his name was naturally changed to Xiaoyao Ding by Ren Xiaoyao.

Seeing that the shopkeepers took over the refining method of Xiaoyao Ding that Ren Xiaoyao had divided, and looked like he didn't care, Ren Xiaoyao's heart moved, and then said: "The number of Xiaoyao Ding for sale is a manifestation of your work ability, so you'd better take this matter to heart." ”

"Yes!" Feeling Ren Xiaoyao's attention, the shopkeepers hurriedly replied.

"Feiyu, how is your Thousand Machine Hall built?" Ren Xiaoyao looked at Gong Feiyu, whose face was a little anxious, and asked.

"Master, the construction of the Thousand Machines Hall is underway, if you wait for another three months, the Thousand Machines Hall will be completed. However, the spirit stones that I had withdrawn before had been spent, but the shopkeepers refused to give me any more spirit stones. Gong Feiyu looked at the shopkeepers present, then at Ren Xiaoyao, and said with an embarrassed face.

"What's the matter, didn't I say that you must vigorously support the construction of the Thousand Machines Palace?" Ren Xiaoyao looked at the shopkeepers, his face was slightly cold, and he said with a smile.

"Big treasurer, it's not that we refuse to support the construction of the Thousand Machines Palace, we really can't afford it. Since the palace treasurer began to build the Thousand Machines Palace, he has taken a large number of materials and spirit stones from us many times, and if he continues to do so, the operation of our branches will become a problem. A branch shopkeeper hugged his fist to Ren Xiaoyao, and said with a depressed face.

At this time, several other shopkeepers also stepped forward to explain.

Only then did Ren Xiaoyao know that in order to build this Thousand Machine Palace, Gong Feiyu had spent more than 30 billion spirit stones, not counting the various materials he had taken from the Bao Branch. The business of each branch is now extremely hot, and the surrounding funds are also needed, and the resources that can be allocated to Gong Feiyu have reached the limit.

"According to your estimates, how many spirit stones will be needed to complete the construction of this Thousand Machine Palace?" Ren Xiaoyao said expressionlessly.

When the spirit stone really needs to be used, it will feel insufficient. Ren Xiaoyao originally thought that the belongings he had accumulated were okay, but he didn't expect that the foundation of the Xiaoyao Treasure Pavilion was still too weak, and he couldn't even build a palace.

"At least five billion lower grade spirit stones are needed!" Gong Feiyu didn't dare to look directly at Ren Xiaoyao, and replied weakly.

Originally, the construction of the Thousand Machines Hall did not require so much cost, but Gong Feiyu used to use spirit stones lavishly, and he wanted to build the Thousand Machines Hall into that kind of unique building, so he chose the best materials, which led to the construction cost of the Thousand Machines Hall far exceeding the budget.

"Five tens of billions!" Ren Xiaoyao lowered his head and muttered to himself, and he was in a dilemma for a while, Ren Xiaoyao now has his net worth, but he can get five hundred billion spirit stones, but in that case, Ren Xiaoyao will have nothing left.

Now, Ren Xiaoyao's situation is extremely embarrassing, the construction of the Thousand Machines Hall is halfway through, and there is no spirit stone if it is built again, if it is not built, it will be lost again after throwing the spirit stone before.

"How can I get the spirit stone?" Ren Xiaoyao lowered his head, constantly thinking about various thoughts. Suddenly, Ren Xiaoyao's eyes flashed and he laughed.

"In this case, the construction of the Thousand Machines Hall will be suspended, and the construction will continue after the Predator Guard and the Easy Warrior are established. ”
