After walking for another stick of incense, Lu Wen finally said, "It's time to get to the entrance!"

Zhao Di only saw two Qi refining stage monks, guarding in front of a small magic circle with a diameter of only two or three zhang, and he didn't see any so-called "entrance" at all.

"Could it be that this magic circle is ......" As soon as Zhao Di thought of it in his heart, Ma Gao blurted out excitedly: "Teleportation array!"

Lu Wen glanced at Ma Gao and said softly: "It's a bit of knowledge, it's indeed a teleportation array, which is specially used to enter and exit the refining room." He took out another red token and said aloud to the two monks who were guarding in front of the magic circle: "Two junior disciples, these three people are new refining disciples, who came here to refine weapons by the order of Uncle Kuang, please dial three inferior refining rooms and teleport us in." ”

The two monks looked at the token carefully, and it was indeed true. One of them took out three blue round jade plates from the storage bag and handed them to Zhao Di and the others.

Zhao Di took a closer look at the jade plate in his hand, one side was engraved with the three numbers "one, two, five", and the other side was densely engraved with many small characters, probably the use of this jade plate and the formula.

The jade plates of the other two are engraved with "one-two-six" and "one-two-seven" respectively.

"This teleportation array can only teleport one person at a time, I'll go in first, and you guys will come in immediately!" Lu Wen commanded Zhao Di and the other three. With that, he walked into the teleportation circle and stood in the center.

The two monks who were in charge of guarding the teleportation array pressed the low-level spirit stones on the array eye, and then a spell hit the teleportation array.

A dazzling white light rose around the circle, and after a while, the white light disappeared, and Lu Wen in the array also disappeared.

"You come in!" one of the guards said to Zhao Di.

Zhao Di entered the teleportation circle according to his words and also stood in the center. A burst of white light flashed, Zhao Di's intuition was instantly blank in his mind, and he quickly closed his eyes, and when he opened his eyes again, he found that he was already in a stone corridor with no end in sight. And that Lu Wen and the other two Qi Refining Stage cultivators were not far from him.

"Come out of here. Lu Wen said to Zhao Di. Zhao Di hurriedly took a few steps forward, only to find that he was in another teleportation circle just now.

A moment later, Ma Gao and Fang Fu also teleported over one after another.

"These two teleportation arrays are a pair of two-way teleportation arrays, and if you want to get out of here, you must also pass through the teleportation array here. Lu Wen said, and then he took out three storage bags, still gave them to Zhao Di and the other three, and said: "The jade plate you just received is the magic weapon that enters each refining room, the number engraved on the front corresponds to the number of the refining room, and the number engraved on the reverse side is the use of formulas, which is very simple, you can understand it yourself." Once you have entered this refining room, no one will disturb you anymore. All of the refining chambers were shrouded in large forbidden circles. Except for the jade plate magic weapon in your hands, even if it is a monk in the Yudan period, it is difficult to break through the door. In this storage bag is twenty catties of refined copper ore, and a month later, Uncle Kuang will personally come to check the results of your refining, and you can do it yourself. ”

After saying this, Lu Wen nodded at the two monks in charge of the teleportation array, stood in the teleportation array, and disappeared after a white light.

Ma Gao said: "Brother Zhao, Brother Fang, let's leave it at that." Then he walked deeper into the stone gallery, looking in both directions from time to time.

After Zhao Di and Fang Fu said goodbye, they also walked towards the depths of the stone corridor.

There are stone houses on both sides of this stone corridor, I don't know what stone is made of, in such a hot environment, it actually reveals a trace of coolness to the touch. Zhao Di looked up at the number of the first stone house, "four or five", and the other side was "one zero". A few steps further, but the numbers on both sides are "sixty-two" and "twenty-eight", which is simply irregular! Zhao Di muttered in his heart. It seems that he only has one room to look through.

After walking through seventy or eighty stone houses, I finally found the "one-two-five" stone house.

Zhao Di took a closer look at the magic technique engraved on the other side of the jade plate, and it was really simple, Zhao Di felt that he could master it after reading it twice.

He put the jade plate into a circular groove on the stone door, the size was really very suitable, and then silently recited a few incantations in his mouth, and with a finger of his right hand, a magic trick hit the jade plate. There was a burst of blue light on the jade plate, and a moment later, a creaking sound sounded, and the stone door opened an entrance half a foot wide on its own. Zhao Di retrieved the jade plate, quickly walked into the entrance of the stone gate, and then a magic trick hit the jade plate again. After a loud sound, the stone door closed again.

Only then did Zhao Di take a closer look at the interior of the refining room.

The stone house is not large, only dozens of zhang wide, and the surrounding walls, including the ground, are made of this unknown stone. On the stone walls on the north and south sides, there are two stone statues of dragon heads with large mouths, on which are written the words "fire of the lungs of the earth". On the west side of the stone house, there is also a stone statue of the dragon's head, but the words "spiritual spring water" are written on it, and below this dragon's head is a pool made of turquoise stones.

It seems that this earth fire or spiritual spring was obtained from these dragon heads.

Other than that, there was nothing else in the entire refining room.

Zhao Di let go of all his divine sense, carefully inspected everything in this stone house, and after making sure that there was no mechanism, he sat on the ground. He didn't rush to comprehend the jade slip given to him by Uncle Kuang first, but took out the small ding, which he had never seen for many years, and put a marrow cleansing pill into it, while holding a blue high-grade water spirit stone in both hands, and meditated on the spot.

In this way, Zhao Di never left this refining room for a whole month.

Although he was still only a monk in the Qi refining period, he could not reach the "Bigu" realm that only monks in the foundation building period had, so he still had to eat some food. But as early as when he was in Liuyunfang City, he bought a lot of "Bigu Pills" to solve the problem of eating.

"Bigu Pill" five low-grade spirit stones are one pill, and if you take one pill, you can stop eating for a month. This is still quite a luxury for a cultivator in the Qi refining period, and it is not a critical moment when he has to meditate for a long time and cannot be interrupted halfway, he is generally reluctant to take Bigu Pill. I'd rather eat every three or five days than waste five spirit stones a month to buy Bigu Pills.

Zhao Di lacked everything, that is, he did not lack spirit stones, so he still quietly bought this Bigu Pill a few times, which was enough for him to use for several years.

This month, Zhao Di has been very busy and busy.

In the first half month, he used Xiaoding to upgrade some pills, and then took meditation and practice. This place is worthy of being a refining place, there is no external interference at all, and such a quiet environment makes him feel very comfortable. In some spare time, he began to understand the purification method taught by Uncle Kuang.

Half a month later, when he began to purify that batch of refined copper ore, he understood why he only gave them twenty catties of ore a month.

Purification is really an extremely strenuous physical task!

It doesn't matter that it takes a lot of spiritual power to suspend the ore in the fire of the lungs and slowly melt, and it also needs to use a large amount of fine divine consciousness to penetrate the strength of the fire on the ground, as well as to control the separation of the refined copper stock solution and impurities in it, and then gather the drops of the refined copper stock solution together to form a large refined copper liquid mass. Finally, the liquid mass is quickly put into the water of the spiritual spring to cool, and a small piece of purified refined copper can be obtained.

In this process, the spiritual power consumed is just that, and Zhao Di is naturally not afraid of replenishing his spiritual power with inexhaustible high-grade spirit stones. But the consumption of divine consciousness made him feel unbearable.

He didn't have any panacea to restore his senses, and he could only rely on meditation and rest to slowly recover his senses.

But in terms of time, it was too late, he could only purify a piece of ore the size of a fist, twenty catties of ore, how could it take ten days and half a month, how could he have time to rest fully.

As a result, when he purified the ore three times in a row, he was slow down because his divine sense was not enough, and the refined copper stock solution burned in the earth fire for a few more moments, so that the refined copper purified was not only slightly darker in color, but also had a lot less aura. Obviously, such refined copper is the product of purification failure.

Zhao Di was a little worried about Uncle Kuang's inspection a month later, if the number of purifications he refined was small and the failure rate was high, he didn't know if he would be expelled from the status of a refining disciple by Uncle Kuang, and then he would probably be assigned an errand that no one wanted to do.

He glanced at Xiao Ding beside him, and said to himself: "It's all because of you, Xiao Ding, that I have to find a very hidden cultivation place, and I finally have such a good cultivation place, but I find that I have to do so much work!

"Hey, Xiaoding, that's right!" he suddenly thought of something, and his originally low emotions suddenly became excited.

(Today, it is said that the fourth watch, the third watch.) ）
