The willow entered the valley in a flash, and slowly walked along a small path, flanked by red rocks that exuded a scorching smell.

A moment later, he was in front of a gray-white stone gate built against a hill at the end of the valley.

The surface of the gray stone door was inscribed with several crimson flame-like spirit pattern marks, and after Liu Ming glanced at it a few times, he walked to the door in a few steps, and knocked lightly twice without hesitation.

After two "bangs".

The stone door was opened a little bit, revealing a young woman with a somewhat dark complexion.

As soon as this woman saw Liu Ming, a hint of surprise flashed in her eyes, and she immediately noticed the mark of a high-ranking guest on Liu Ming's clothes.

"Dare to ask the seniors their names, is there anything wrong with this?" the young woman asked a little suspiciously.

"In Xia Liuming, he is the new guest in the meeting, and he specially came to visit Huang Zhen Daoyou this time. Liu Ming said with a smile.

"It turned out to be Senior Liu, this is really unfortunate, my father is refining a spiritual weapon in the refining room, why don't I go and tell me?" When the young woman heard this, she hesitated for a moment and said truthfully.

"It turned out to be Miss Huang, so there is labor. Liu Ming bowed his hand slightly.

"Senior, please wait a while, I'll go back as soon as I go. The young woman slammed the door back behind and went to report it.

After half a cup of tea, the door of the cave was opened again with a "creak".

This time, a middle-aged man in his forties and fifties walked out of it, with dark skin and thick hands and feet, and at first glance he thought he was an ordinary farmer in the mortal world.

"It's Liu Daoyou, it's Huang Zhen below, and the little girl was rude before. I hope forgive my sins. Fellow Daoist, please come into the cave for a while?" the swarthy man said politely after looking at Liu Ming.

"Huang Daoyou is polite. That's a bother below. Liu Ming was a little surprised in his heart, but he didn't show the slightest difference on his face. And thanked him and left the stone gate.

As soon as you enter the gate, there is a wolf more than ten zhang long, and inside is a hall twenty or thirty zhang wide, the void is filled with bursts of hot breath, and the ground and the surrounding rock walls are showing a layer of dark red.

A moment later, Liu Ming, led by the swarthy man, came to another stone room for entertaining guests, and the two sat opposite each other and talked angrily.

"So to speak. Liu Daoyou want to ask Xia to help refine a spiritual weapon?" After a while, Huang Zhen looked at Liu Ming and asked.

"Not bad. I heard that Brother Huang Changfeng will be the best refiner,. But I don't know how sure you can be if you are given enough materials to refine a medium-grade spiritual weapon?" Liu Ming said with a smile.

"It depends on the quality of the materials and the requirements of the Taoists. Huang asked himself that in the way of refining, it was not a short time to be immersed. The general medium-grade spiritual weapon, if it is refined by Huang. Naturally, there won't be any major problems. But in the forefront, if the refining fails, I won't compensate for any materials. Huang Zhen pondered for a moment and then slowly replied.

"It's nature. As long as Brother Huang can help him refine successfully. Thank you!" Liu Ming replied without thinking, and at the same time took out more than a dozen pieces of light blue ore with one hand.

"Shui Xuanshi!" Huang Zhen recognized the thing in Liu Ming's hand at a glance, and the look of surprise on his face flashed.

These rare ores were very common in the deep-sea mines of the time. But in the outside world, it is a rare and excellent refining material.

"It's more than enough to use these as a reward, I don't know what kind of medium-grade spiritual weapon you want to refine?" the dark man raised the corner of his eyes. No longer hesitating, he asked directly.

When Liu Ming heard this, he didn't speak. Flipping with one hand, a black droplet the size of a bean grain appeared out of thin air, and there were still a few wisps of black mist lingering on the surface of the body.

"It's ......"

The big man looked at it carefully, and a hint of suspicion flashed on his face.

But after Liu Ming smiled, suddenly his palm flipped again, and the black droplets immediately fell down and smashed heavily on the seemingly solid and abnormal stone slab.

With a "boom", the entire stone chamber shook!

And on the stone slab in front of Liu Ming's feet, there was a deep hole the thickness of another finger.

"One yuan heavy water! Daoyou actually has such a treasure. Huang Zhen lost his voice.

"Daoyou is really well-informed. Liu Ming said lightly, and then grabbed the void in the stone cave below with one hand.

As a result, after a "whoosh", a yuan of heavy water immediately flew out of the stone cave, and in a flash, it sank into Liu Ming's palm again.

This is also Liu Ming's physical strength, which is far from being comparable except for the condensation period, otherwise it would never be able to be ingested from the ground so lightly.

Liu Daoyou said with a smile, since he is a refiner, how can he not even know such materials, but it is the first time he has seen the real thing with his own eyes. Huang Zhen looked at the thing in Liu Ming's hand without blinking, and there was a hint of obsession on his face.

"Since Huang Daoyou knows about this, he won't go around in circles. This time, I want to ask Your Excellency to refine a 'Heavy Water Bead'," Liu Ming said directly and simply.

"Heavy water beads?" Huang Zhen heard this, and finally sobered up a little from his obsessive look, and took a deep breath.

"What's the matter? Could it be that Daoyou can't refine it?" Liu Ming frowned slightly.

"Liu Daoyou, don't get me wrong, I, Huang, do it myself, how can there be a reason why I can't refine it. It's just that if you only refine a medium-grade spiritual weapon like this, it's really a waste of this material. If Daoist friends can find a water attribute spiritual material to assist, they can refine the heavy water bead into a superb spiritual weapon in the next seventy percent. Huang Zhen waved his hand again and again and explained.

Daoyou laughed. There is such a thing as spiritual materials, how can there be such a thing in the hands of the next hand. Although Liu had occasionally heard people talk about this kind of material before, he really didn't know much about it, can Brother Huang give me some advice?" Liu Ming's heart moved, and he asked in an inquiring tone.

"Liu Daoyou is not a refiner, and it is normal that he doesn't know much about spiritual materials. Spiritual materials are excellent materials for refining the best spiritual weapons, and they themselves are similar to spiritual. If an ordinary top-grade spiritual weapon wants to upgrade its level and finally achieve the prototype of the magic weapon of the thirty-six prohibitions, it needs spiritual materials. And for a treasure like one-yuan heavy water, if you add spiritual materials with corresponding attributes when refining, you can naturally greatly improve its grade. However, spiritual materials themselves are a kind of anti-heavenly existence, and it often takes tens of thousands of years to give birth to one or two, which is an extremely common thing. Therefore, even if the predecessors of the True Dan Realm wanted to find this kind of material, it would be extremely difficult. Huang Zhen explained slowly.

"I see, I have seen it in the next elder, but Liu has no spiritual materials. If it takes to refine the heavy water beads of a medium-grade spirit weapon?" Liu Ming nodded thoughtfully, and suddenly asked.

"After twenty days, you can come to me and get the spirit weapon. In addition, refining heavy water beads also requires some other auxiliary materials, but Huang can match them, but it's just ......" Huang Zhen said after thinking about it.

Although Huang Daoyou is assured, the previous Xuanshui Stone is just a reward, and Liu will bear the cost of auxiliary materials. I'll be there for me in the next twenty days. Liu Ming nodded and said, thinking of the hunting of the Blood Locust Beast after half a month, it seems that he can only come and get it after he returns.

Seeing that Liu Ming agreed so happily, Dahan no longer hesitated to accept the matter of refining heavy water beads.

In the following time, Liu Ming told him about the effect prohibition that needed to be integrated into the heavy water beads, and naturally he still required it to refine all the weight increases, and Huang Zhen naturally had no objection to this, so he made a routine oath on the spot.

Liu Ming didn't stay here long, and after leaving behind a yuan of heavy water and some water stones, he left directly.

When he left the valley, he took off and walked away, and after a short time he returned to his cave, and after telling Lian'er and Hong'er not to see any visitors, he turned around and entered the secret room.

After Liu Ming sat down cross-legged in the secret room, he shook his sleeves, and a cloud of black gas flew out, and after dripping and condensing in front of him, it turned into a mini bone shield with nine skull patterns.

Liu Ming fell into deep thought while playing with the things in his hand.

After a conversation with Huang Zhen, he had already determined that the part of the spiritual materials recorded in the Fire Refining Sutra was correct, and if you wanted to refine the prototype of the thirty-six magic weapons, you really had to use spiritual materials.

The Nine Peaks Skull Shield is already a top-grade spiritual weapon with a thirty-five ban, and now it is only one step away from the thirty-sixth ban, and once it is successfully refined, it can transform into a magic weapon prototype.

And the spiritual materials needed to refine this shield, he still has a lot in his hands, which should be enough for him to complete the last layer of forbidden sacrifice.

And if he has a bone shield with thirty-six prohibitions, I believe that even in front of ordinary crystallization stage monsters, it will be enough to protect himself.

When Liu Ming thought of this, his heart became hot.

You must know that a true pill realm like the Siren Emperor only has a prototype of a magic weapon like a Xuanyin needle in his hand. Thinking of this level of treasure, even in the cultivation world of the Zhongtian Continent, it is extremely rare.

However, if you really want to raise the Nine Peaks Shield to the thirty-six prohibition, it will have to be after the detoxification.

And I'm afraid he will have to spend some time studying the way of refining weapons.

After all, he had never thought about handing over the Nine Peaks Shield and spiritual materials to other refiners for refining.

In the next few days, Liu Ming sold some of the remaining ores on his body, along with some of the remaining top-grade spirit stones, and temporarily purchased a low-level flying sword spirit weapon and some talismans that could be used in the deep sea in the Fang Market of Qingyu Island.

He had already decided in his heart that if necessary, the best spiritual weapons such as the Golden Sand and the Nine Peaks Shield would not be used lightly, especially the latter.

Otherwise, once he is really targeted by a strong person above the crystallization level, he will be in big trouble.

After making these preparations, he spent the next few days meditating and pranayama in the cave to recuperate and recuperate.

Seven or eight days later, Liu Ming and Xin Yuan immediately left Qingyu Island together and flew all the way to Fang Yao's island. (To be continued......)
