The original beautiful scenery of the Heavenly Thunder Purgatory was completely destroyed, and those green mountains were all bare, but these mountains still contained a strong spiritual aura.

If it is related to Shen Xiang and the others, this Heavenly Thunder Purgatory is related to the Heavenly Thunder Demon Lord, as long as the energy of the Heavenly Thunder Purgatory is consumed, it is equivalent to the consumption of the energy of the Demon Lord, but this Heavenly Thunder Purgatory is frantically absorbing spiritual energy from the outside.

"It seems that I have to speed up the time to refine more Dan!" Shen Xiang's eyes shot out of essence, looking at the huge mountain in the distance that was wrapped in a huge magic treasure furnace, that mountain had been instantly refined by him, but there was not a lot of aura in it, and the quality of the refined Dan would not be very high!

Seeing Shen Xiang refining Gao Shan with the huge magic weapon furnace, Yun Xiaodao and they all exclaimed in their hearts, if Shen Xiang often used this way to refine the pill, there would be no need for materials at all!

After Shen Xiang refined a mountain, he felt that it was not enough, so he controlled the magic treasure furnace to move to a nearby high mountain, shrouded it, and then incinerated it into pure energy, fusing with the energy formed by the previous mountain.

"Brother Shen, how did you send the flames over?" Yun Xiaodao felt very amazing, he was beside Shen Xiang, and he didn't feel the temperature rise, and there was a very strong fire burning in the magic furnace in the distance, which could burn the flames of a tall stone mountain!

Shen Xiang is indeed not using the flame in his body now, now he is just refining poorly, and the distance is far away, although he can use his own flame, but the consumption is huge, and it is very simple to control with divine power, and now the flames he uses are all spiritual fire, he extracts the aura of fire attribute from the aura according to the method in the art of heavenly refining, turns it into a pure flame, and injects it into the magic treasure furnace, so that he only consumes divine power!

The reason why the Divine Killing Technique and the Heavenly Alchemy Technique are put together is because the Heavenly Alchemy Technique has high requirements for the individual's divine consciousness, while the Divine Killing Technique is something that can make people cultivate the Divine Soul!

According to Duan Chong, the Heavenly Refining Technique is much more powerful than the Heaven and Earth Killing Technique, and the Divine Killing Technique can only be regarded as the foundation of the Heavenly Alchemy Technique**.

Duan Chong had told Shen Xiang before that he must not use the Heavenly Refining Technique in front of others, but now it was a last resort, otherwise Shen Xiang would never use this anti-heaven magic skill in the Demon Lord's territory.

The magic treasure furnace is as high as 10,000 zhang, like a translucent golden crystal, standing above the earth, overhead the sky, looking at the past from a distance, magnificent and shocking! The lowest layer of the magic treasure furnace is burning with raging fire, and in the middle are those giant mountains that have been incinerate, under Shen Xiang's refining, the giant mountains that were originally thousands of zhang high will become pure gaseous energy, and all those impurities will be shot out, leaving only the best things!

The top layer of the magic treasure furnace was an aerosol that could be used to condense pills, but Shen Xiang felt that it was not enough to condense high-quality pills, so he stored them there for the time being!

This is all because Shen Xiang has the support of vast divine power in his divine sea, fortunately, he had devoured a Heavenly Demon Monarch with a powerful divine sense before, allowing his divine soul to enter the realm of transcendence, otherwise it would be difficult for him to do all this now!

In just three hours, he had refined hundreds of mountains, and these huge mountains contained more energy than he had imagined.

It was the first time he had used the Heavenly Alchemy Technique to refine the giant mountain into a pill, but this was not difficult for him, it just required the release of a large amount of divine power, which was easier than when he was just refining the Illusory Ghost Eagle.

Now he was able to refine one after another so smoothly, thanks to the experience he had accumulated when refining the Illusory Ghost Eagle before.

"Brother Shen, isn't it okay yet? It's a hundred mountains. "Yun Xiaodao, they have been immersed in this black lava pool for a while, and now they are used to that kind of torture, although it will not hurt to cry wolf, but it is very boring, they want to end this day quickly.

"It's still early, do you think these mountains are all treasure mountains? Without much aura, the quality of the refined Dan will not be high!" Shen Xiang said: "If you want to refine high-quality Dan in this way, you need to highly compress the energy and temper it repeatedly! Just like striking iron, you have to fold and beat a very large piece of iron repeatedly, remove the impurities at the same time, and fuse and compress the essence together, so as to forge the best refined iron, and this is also the principle of alchemy!"

"For example, when you cultivate, you need to repeatedly fuse and squeeze your true qi together to improve the quality, and then open up the dantian through these high-quality true qi, so that the dantian becomes a container that can hold more and stronger true qi. ”

Zhu Rong said: "If it goes on like this, it won't be long before the surrounding mountains are all refined by you, what will you refine at that time?"

Shen Xiang said with a smile: "When the time comes, you will know the Dao, I estimate that at least 10,000 mountains can be of great use to refine the Dan, and it should be able to be regarded as a heaven-level lower grade Dan!"

Shen Xiang can now refine the Heaven-level Lower Rank Pill, which made Zhu Rong and the others surprised, this is equivalent to the strength of the Dan King, they know very well the growth process of Shen Xiang on the road of alchemy, this is really too fast!

Shen Xiang saw their expressions, shook his head and smiled: "If I use normal means to refine normal Dan, I can only refine the middle grade of the ground level at most, and I am still some distance away from the top grade of the ground level!

For example, the Super Iron Bone Pill he refined was not a normal refining method, but it belonged to the Heaven Grade Lower Grade Pill, and now he used the mountain alchemy to do the same.

Duan Chong secretly exclaimed beside him, according to Shen Xiang's current alchemy level, that was a great Dan master, and he could soon become a Dan Sect, he was a powerful martial artist who attacked and killed strongly, but at the same time, he was an alchemist of this level.

"Ten thousand mountains...... There are only more than a thousand around here at most!" Xiao Qiu wanted to break his head, but he couldn't think of any way Shen Xiang would use to solve this problem, and the same was true for the others.

After half a day, the sky became dark red, it was close to night, the stars were covered by a red halo, where Shen Xiang was where they were, the surrounding mountains were gone, and they were all refined into the magic treasure furnace by Shen Xiang, "Two thousand three hundred and twenty-one, no, I can't see the mountains in the distance!"

Shen Xiang's refining speed is getting faster and faster, and the energy compressed in the magic treasure furnace is getting more and more, and now he is continuously consuming divine power to perform the Heavenly Alchemy Technique.

"Keep your eyes open!" Shen Xiang smiled, releasing a large amount of divine power, and then let out a low roar, only to see a large pale golden mist suddenly appear on the bare flat ground around him, enveloping all directions, as if covering the entire Heavenly Thunder Purgatory.

These pale golden mist dispersed, and dense mountains suddenly appeared around them, which made Duan Chong and the others stunned!
