This stone secret room is a square building, the length and width are seven or eight zhang in size, in the center of the room there is a round platform more than one zhang wide, there is a large tripod on it, and there seem to be some holes on the platform below the tripod. There is a dark yellow dragon head sculpture on each of the four walls, the dragon's mouth is slightly open, and there is an earthy yellow futon in the corner not far away. The platform and walls are also made of dockstone, and the whole is gray.

The big tripod shape is huge, majestic and solemn, the craftsmanship is exquisite, the tripod body is cast with animal patterns all around, and there is a top cover on the tripod. Square lips, wide edges, vertical ears, hanging abdomen and bottom, three legs are placed below, which is close to the hoof feet, the height of the top is more than four feet, and the diameter is three feet. The tripod has thick vertical ears, slightly outwardly skimmed, decorated with two concave chord patterns on the outside, folded along the broad margin, the abdomen is transversely broad, slightly drooping, and bears three hooves. The neck of the vessel is decorated with cloud and thunder patterns as the ground, and the circumference is decorated with two types of six groups of relief animal face patterns, and the upper end of the foot is decorated with high-relief animal face patterns, and the lower part is lined with three convex string patterns.

On the outside of the platform, there are also eight dark yellow miniature dragon heads, which are lifelike. Moreover, the mouth of the dragon's head is slightly raised, which is just aimed at the big top in the sky above the center of the platform, making a spitting posture, which is very realistic.

After the two of them entered, Hall Master Ning swept the token on the stone door again, and the stone door closed on its own again. Then he put away the token and took out a similar token and handed it to Xiao Tian.

"This is the token that controls the stone door of the secret room, you put it away. As soon as the door was closed, it was cut off from the outside world. If someone is inside, the stone gate will change from five colors to a single red, and other tokens will be useless. Unless several Jindan monks attacked together, no one could enter from the outside. The Hall Master Ning explained in detail.

Xiao Tian wrote it down carefully, took the token in his hand and put it away after a little detail. Then the Lord of Ning Hall began to explain the things in the stone room, and the way of explaining everything in detail was very similar to Xiao Jingnan.

"Senior nephew, these dragon heads are the fire mouth of this house, and the mixed yuan mountain fire required for alchemy is spewed out from these twelve dragon heads. And according to the need, you can also adjust the size and height of the flame by yourself, and the specific driving method is recorded on this jade slip. As he spoke, he took out another jade slip and handed it to Xiao Tian.

The jade slip was rectangular, flat on one side, slightly protruding on the other, pale green, with very little text on the surface, and some strange symbols. Xiao Tian took it in his hand and checked it carefully, but he didn't find anything related to this stone room at all.

"Haven't you used the jade slip?" Seeing Xiao Tian's appearance, Lord Ning asked at the exit.

I think I've heard of it, what are you doing?

"It was indeed the first time that the disciple had seen the real thing. Xiaotian honestly admitted.

"Well, your cultivation is too low, and it's really not suitable for using jade slips. This jade slip is made of Xuanjing, and it can be engraved with divine consciousness by relying on spiritual power, and it can also be read in the same way. You put it on your forehead and gather spiritual power there. Hall Master Ning shook his head, and still said to Xiao Tian.

Xiao Tian did as he was told, and paragraphs of text suddenly appeared in his mind, all of which were related to this stone room. This jade slip is really easy to use, so much content, if you write it on paper, how thick a book you have to use, just turn it over for a long time. Unexpectedly, he had learned knowledge other than refining weapons here, and Xiao Tian secretly felt funny in his heart.

"It takes a lot of mind and spiritual power to use the jade slip, and your cultivation can't last long, you take the jade slip, and then take a slow look." Lord Ning interrupted Xiao Tian.

"Yes, Uncle Shi. Xiao Tian stopped when he heard this, and put away the jade slip.

"But the palace is basically made of jade slips, and the books are not easy to use here. Moreover, refining weapons also requires a lot of mental and spiritual power, so you still have to improve your cultivation if you have time. Hall Master Ning admonished again.

It seems that it is still necessary to improve cultivation, and everything related to cultivating immortals seems to be related to the level of cultivation, but the degree of influence is different.

Then the hall master Ning didn't say much to Xiao Tian, pointed to the top of the big ding, and made a legal decision, and the ding cover floated in the air. Then he took out some silver-gray ore, and as soon as he cast a spell, the ore flew into Dingzhong.

Closing the lid, Hall Master Ning sat down on the futon in the corner, while Xiao Tian stood beside him. He struck a spell at all the dragon heads, and the dragon heads immediately opened their mouths, spewing out blue flames with thick bowl mouths. At this time, blue pillars of fire also appeared in the holes under the ding. All the flames and pillars of fire sprayed around the body and bottom of the Great Ding.

"What I am refining today is Emperor Yin Silver, which needs to be burned with maximum firepower. I forgot to tell you that when the fire is at full power, there will also be mixed yuan mountain fires coming out of this ding, but it is only used when high temperatures are needed, and there is still a small fire to slowly adjust when it needs to be finely fired. Hall Master Ning explained to Xiao Tian while not stopping.

Soon after the flames erupted, the room became extremely hot, and the air was filled with subtle fluctuations, which made Xiao Tian a little unbearable.

"The situation of the material in it must be sensed by the divine sense, and when it needs to be flipped, it will be used to hit the tripod, and it can only be taken out after the refining is completed. This Emperor Yin Silver only needs to be cauterized at high temperature for half a day, but some materials take a long time and take several days. You can't Bigu now, but you will go to the upper hall to get some Bigu Dan, and one can be full for ten days. The hall master Ning stared at Da Ding, but he still kept explaining to Xiao Tian.

Bigu Dan, there is also this kind of good thing, it is indeed convenient, but Xiao Tian still likes to eat normal meals, since he came to the Yuanxu faction, the delicious food he eats every day is unforgettable.

Afterwards, Hall Master Ning also looked at the refining of the materials, and kept talking to Xiao Tian about the knowledge and skills of various refining weapons, Xiao Tian wrote them down one by one, and asked questions from time to time. During the commentary, Master Ning did not forget to play the law and adjust the firepower and materials.

After four or five hours, the material was finally refined. The Lord of the Ning Hall struck a spell at the dragon's head, stopped the flames, and then waited for half a pillar of incense before opening the lid.

A magic battle was struck, and a ball of shiny silver metal floated out, and the Ning Hall Master took out a jade box, pointed at the metal, and the metal flew into the jade box.

"In this way, even if the refining is completed, someone will clean up the residue and impurities, but if it is continuous refining, you have to do it yourself. Let's go, let's go out. Then Hall Master Ning opened the stone door and walked out with Xiaotian.

"This Emperor Yin Silver refining method is relatively easy, but it is extremely difficult to accurately grasp the heat, and if there is a slight deviation, it will fail. In two days, you start refining with the simplest Xiahuo copper, and then this Emperor Yin Silver. The lodging and eating are outside the temple, so you can ask in the temple later. Uncle Shi, I'm going to go to the next level of refining, so don't leave it at that. Out of the stone room, as soon as the master of the Ning Hall gave advice, he sent Xiaotian away.

Xiao Tian also respectfully said goodbye, he was already hungry now, and he just wanted to go up and eat quickly.
