Zhao Di and the others only waited for a moment, and the thick clouds changed. A burst of spiritual light flashed, and a gorgeous cloud ladder two or three zhang wide and nearly a hundred zhang long stretched out from the thick clouds, leading from the front of the small pavilion to the belly of the mountain deep in the thick clouds.

The three of them hurriedly stepped on the ladder and walked towards the mountain.

After walking through the cloud ladder, the thick clouds were left behind, and Zhao Di and the others saw the true face of this hidden peak. This peak is really different, not only is it not like other peaks, there are green grass and trees, but the rocks on the peak are dark red. And the three of them also clearly felt that the temperature of this grassless Zhaoyin Peak was much higher than that outside.

Although the cultivation has reached the level of Zhao Di and the others, it is already cold and hot, and the three of them naturally don't care about the temperature changes when they are idle. However, the temperature of this hidden peak is at least a lot higher than that outside. If a mortal enters, I'm afraid that it won't last long and the heat will be unbearable.

The three of them walked silently for a short distance of mountain road, and then came to a stone hall. On a red boulder in front of the hall, there are three strong and powerful characters of "Baixu Hall".

This stone hall is made of a kind of snow-white and crystalline jade, which is particularly dazzling against a dark red background.

As soon as the three of them stepped into the temple gate, they immediately felt that the temperature had suddenly dropped a lot, and it was about the same as the temperature outside.

Zhao Di immediately remembered the name of the snow-white jade used in this stone hall - Hanyu.

I don't know which book Zhao Di has read, Hanyu is also a common refining material, but the spiritual power contained in different Hanyu varies greatly. Usually according to the spiritual power from less to more, it can be divided into a hundred years of cold jade and a thousand years of cold jade. If the 100-year-old cold jade is used as the main material, you can make medium-grade or even high-grade magic vessels. If you use thousand-year-old cold jade, you will have the opportunity to refine the best magic weapon.

The cold jade used in this stone hall, judging from the strength of the spiritual power it emits, is only ten or decades of cold jade, but the entire hall is built from this material, and it is indeed a big deal.

In the stone hall, there was a middle-aged monk about forty years old, who was sitting on the only Taishi chair in the hall, closing his eyes and taking a nap.

Judging from the fluctuations of spiritual power emanating from this monk, Zhao Di said that this person's cultivation was slightly lower than that of Old Man Ma, and he should be a monk in the early stage of foundation building. Whether it is cultivation or image, it is very consistent with the Uncle Kuang that the three of them are looking for.

The three of them glanced at each other, but no one dared to make a sound, just stood quietly.

Thinking that they would have to work under this foundation building period monk for a long time in the future, none of the three dared to make a noise to disturb them, so they could only stand stupidly and motionless, not even daring to breathe.

This station actually stood for seven or eight hours.

Even if it was the physique of an immortal cultivator, after standing down in one posture for such a long time, the three of them all felt a little soreness in their legs. But the middle-aged monk still showed no signs of waking up.

Ma Gao was the youngest of the three, and he was the first to lose his surname, and when he was about to wake up the middle-aged monk, the other party suddenly yawned and opened his eyes.

Before the three of them could speak, the middle-aged monk took the initiative to say, "The three of you are the new outer disciples of this year." Yes, after standing for so long, it can be regarded as perseverance. ”

"I'm the Uncle Kuang you're looking for, but if you want to become a refining disciple, I still have to take the test, not just anyone can master the alchemy technique! In addition to perseverance, the necessary skills and knowledge are essential. The monk surnamed Kuang continued.

"Assessment? Why didn't the old man Ma mention this? He just mentioned lightly and asked me to see the classics about refining weapons. Zhao Di thought in his heart, and instantly scolded the monk surnamed Ma countless times in his mind.

However, Uncle Kuang didn't give these three people time to prepare at all, and as soon as he said that he wanted to be assessed, he immediately pointed at Zhao Di and asked, "Let me ask you first, do you know what is particular about the fire that needs to be used in refining?"

Fortunately, it's just a matter of common sense, and Zhao Di has indeed read the relevant classics, and after a little thought, Zhao Di replied: "Refining tools generally need to use innate true fire. The so-called innate true fire refers to an innate flame that only has monks above the foundation building period and comes from the spiritual power in the dantian. This kind of innate true fire does not need to be cultivated, as long as the cultivation reaches the foundation building stage, it will be possessed. In addition to the Innate True Fire Refiner, the Earth Fire Refiner, that is, the fire of the earth's lungs, is usually used instead of the Innate True Fire Refiner. The fire of the earth's lungs comes from some geological depths of the earth, and the power is a few points higher than that of ordinary innate true fire. If the fire of the earth lungs is properly regulated and utilized, it is more suitable for refining weapons than the innate true fire. Because the innate true fire requires a great deal of spiritual power, it is not suitable for long-term use. ”

Zhao Di paused, and then continued: "It is said that there is also a small way to use the demon fire refiner spewed out by some demon beasts with the surname of the second level or above. The specific situation is not very clear to the nephew. ”

"Very good!" The middle-aged monk nodded and said approvingly: "I even know how to use demon fire refiners, it seems that I have studied the classics related to refining." ”

Except for Zhao Di, the two Qi Refining Stage cultivators glanced at each other, and they both saw envious expressions in each other's eyes. Obviously, this Zhao Di has passed the assessment.

Immediately, the middle-aged monk pointed at Fang Fu and asked, "Tell me, what raw materials and methods are usually needed to refine a magic weapon?"

Fang Fu was silent for a while, as if sorting out his thoughts, and then replied unhurriedly: "Uncle Hui Kuang, generally speaking, in addition to the main material ore, the spirit spring water, emery and other auxiliary materials, the refining tool also needs a certain number and grade of spirit stones. In addition to the process of purifying materials, it is also necessary to master a certain knowledge of formations, because several common small formations need to be used in refining magic weapons. There are some types of magic weapons that need to be painted with some runes when refining. ”

"Well, that's good. The middle-aged monk nodded, satisfied with Fang Fu's answer.

Then it was Ma Gao's turn, and he was asked, "What methods do you know to purify the raw materials needed for the refining tool from the material ore?"

This question is obviously the most difficult of the three questions, Zhao Di on the side secretly said in his heart that he was lucky, if he was allowed to encounter this question, he really didn't know how to answer.

Sure enough, Ma Gao didn't know much. Beads of sweat the size of beans oozed from his forehead, and he replied hesitantly: "This purification, this, the master and nephew only know, can use real fire to melt the ore, and then, this impurity will be burned or lost, and it can have the effect of refining and purifying." ”

The middle-aged monk actually nodded and said, "Well, burning with fire is indeed the most commonly used method, but it needs to be controlled with divine sense, otherwise the raw materials will be easily destroyed by the real fire and some of the power." In addition to this, there are indeed many methods to refine and purify. In the coming year, if you are diligent and studious, you will naturally be able to master a skill. ”

The three of them were overjoyed, and the implication of Uncle Kuang's words was very clear, that is, these three people had passed the assessment.

"Alright," the middle-aged monk stood up and said, "There is a jade slip here, which records several techniques for purification, and after you have carefully consulted it, you can try it out." As he spoke, he waved his right hand lightly, and three blue rays of light slowly flew in front of the three of them and stopped, and they were three identical cyan jade slips.

Seeing that Zhao Di and the others had put away the jade slips, the middle-aged monk said again: "In half an hour, a senior brother will take you to the refining room, and give each of you a batch of refined copper ore, you can refine the refined copper well, and I will check the refining progress and effect of each person in a month." ”

After speaking, the middle-aged monk shook his sleeves and left the cold jade hall.

It didn't take long for a young monk surnamed Lu Mingwen who was on the thirteenth floor of the Qi Refining Stage and was only one step away from entering the Foundation Building Period, and left the Baixuan Hall with the three of them and walked towards the refining room.

The group walked in the belly of the mountain for more than half an hour, and Ma Gao couldn't help but ask: "Senior Brother Lu, how deep is this refining room underground? We have been walking down for half an hour, but I am afraid that we have already entered the ground several hundred meters deep. ”

Lu Wen said coldly: "What's the hurry, it's coming soon." The refining room is all used to take the fire of the lungs of the earth, how can you do it if you don't get close to the ground!"

"It's good to arrive, this place is getting hotter and hotter, you don't need some spiritual power to protect your body, I'm afraid that you will sweat and collapse from the heat. Ma Gao muttered in a low voice.
