Chu Tianxing immediately set off, but when he saw Yun Tianxue and Yun Tianshuang, they were unexpectedly in a place with extremely high temperatures.

Yaowang Furnace ......

"What is she doing here?" Chu Tianxing immediately rushed to Yun Tianshuang's side and saw that she had been held in Yun Tianxue's arms and unconscious. Hurriedly checked for her and found that she had been severely poisoned by fire.

"I didn't know, but when I came to look for her, I found that she wasn't in the room. As a result, she followed the traces she walked to look for it, only to find that she had come here and had collapsed in a coma. Yun Tianxue said to him anxiously.

thinks that her sister should have so many tribulations, and finally got a little better and encountered such a thing again.

Chu Tianxing immediately found that Yun Tianshuang's situation was even more serious, because she was not only hit by the fire poison, but also because she had not cleared the cold poison in her body before, which caused her body to have a very fierce confrontation with the fire poison at this time, directly making her body become a battlefield, and each occupying the territory was fighting.

To put it simply, she will be unconscious again, and more seriously...... She could fall immediately.

Immediately carrying her to the room, Lingling used ice spiritual power to calm the injuries in her body. Chu Tianxing told Yun Tianxue and Chu Lingling that he knew that saving people now was like fighting a fire, and if he was one step later, Yun Tianshuang would really die.

"Hmm!" Yun Tianxue and Chu Lingling immediately ran away with Yun Tianshuang in their arms and ran towards Yun Tianshuang's room.

Chu Tianxing cast his eyes at the huge Dan furnace that was ten meters high beside him, and saw that there was a silver flame burning inside. On the outer wall of the Dan Furnace, only the lowest level of gems shone brightly, blooming with an emerald green light.

"Why did she come here?" Chu Tianxing couldn't quite figure out why Yun Tianshuang suddenly ran near this Medicine King Furnace, because of her intuition as a pharmacist and an immortal-level wood spirit body?

But now was not the time for him to think about it, and he knew he was going to save her now. He also immediately found an elixir in his mind that could cure her illness—the Yin and Yang Mixed Yuan Pill—a heaven-grade elixir.

However, it is said to be a heaven-level inferior grade, and it is still extremely difficult to refine it with the situation that Yuntian Frost has just broken through the distraction realm.

Because if you want to refine a heaven-level elixir, the most basic condition is to reach the fusion realm at least!

Chu Tianxing can't control so much now, he can only rely on his own soul power in the late stage of the fusion realm to try, and the key to alchemy is also soul power. This was also the first time he had made alchemy in the true sense of the Heavenly Spirit World.

The materials of the Yin Yang Mixed Yuan Pill were all available in the Medicine King Valley, because he had mastered the Medicine King Valley, as long as he had a thought, a large number of medicinal herbs would automatically fly towards him and let him use them.

Chu Tianxing immediately went through the refining methods and requirements of the Yin and Yang Mixed Yuan Pill in his mind and mastered the process.

Confirm that the Danhuo is no problem, as a Heavenly Saint Dragon Flame or above, it is enough to refine this pill.

It's no problem to confirm the Dan Furnace, even if the Medicine King Furnace, which is the treasure of the Medicine King Valley and the Zhengu Valley, only activates the first layer, it can easily refine the pills below the immortal level. He even showed through the data status of the Divine Demon Record that the effect of the first layer of this Dan Furnace was actually "increasing the probability of success in alchemy by 40%, and increasing the quality of successful alchemy pills by 20%", which was already a rather anti-heaven attribute.

In the end, it was confirmed that the chances of him refining the Yin Yang Mixed Yuan Pill were only ...... 8%。

It means that even if he uses the Medicine King Furnace to refine the Yin and Yang Mixed Yuan Pill, his total chance of success is only 48%, which is still less than 50%, that is, less than half of the chance of success.

But he couldn't do that much now.

With the situation of Yun Tianshuang's body being poisoned by cold poison and fire poison, her current strength can only last for another half an hour at most, and once half an hour passes, it will be difficult for the immortals to be saved.

Chu Tianxing, in order to ensure the maximum chance of refining success, took the risk of using the 'Three Flames Kaiyuan' of the Medicine King Valley's secret tradition, which meant that he had to use three kinds of Dan Fire to refine this Yin and Yang Mixed Yuan Pill at the same time.

With his current situation, the first one is naturally the Holy Dragon Flame, the heaven-level Dragon Flame.

The second is ......

"Heavenly Dao Soul Fire, go. ”

A yin flame popped out and fell into the Medicine King Valley, causing the silver flames that were originally burning inside to smear a layer of purple, and also lowered the temperature here a little, revealing some coldness.

The origin of this soul fire is naturally the remnants of the soul of Emperor Guanghan.

The last one is......

"Wood Spirit Fire, go!"

took out a strange mass of substance, separated a part of it, and bounced it into the Medicine King Furnace.

Directly using the wood soul as the material ignited the wood spiritual fire, making the original purple and silver color inside have some more emerald green, and it looks full of vitality.

After Chu Tianxing did this, his lips immediately turned pale, and there was not much blood on his face.

He is now completely using Yun Tianshuang's wood spirit power, and unlike Yun Tianshuang, he can only use it and can't restore it, so he uses a little less.

The simultaneous control of the three kinds of Danhuo made his spiritual power consumption also extremely large, fortunately, he had the support of his soul power in the late stage of the Fusion Realm, so that he would not faint and still be able to keep calm and control the operation of the Danhuo inside.

Unfortunately, he couldn't use the Strength Pill to forcibly improve his strength realm now, because that would only cause the three pills in the Medicine King Furnace to get out of control and instantly burn all the medicinal materials inside.

After using the Three Flames Kaiyuan to control the fire, he forcibly operated in the Dan furnace with his strong soul power, forcibly stripped the essence of various medicinal materials, and burned the remaining residues with the Dan Fire to become the fuel for these Dan fires.

A chaotic ball of liquid of black and white transparent matter was suspended in the Dan furnace, tumbling on the three Dan fires.

Chu Tianxing had already developed his strength to the extreme, meticulously refining his first furnace of heaven-level elixir without making any mistakes, or a furnace of elixir that had to be successfully refined.

Once the essence has been stripped out, it is time to sublimate it again.

The sinking of yin and the rise of yang will eventually condense into Dan.

The three kinds of Dan Flame constantly burned this liquid, and wisps of residue also separated from this mass of liquid and disappeared in the high-temperature Dan Fire.

This mass of liquid, which represented the essence of many medicinal herbs, also became more and more pure, and it looked more and more black and white, no longer so chaotic.

Chu Tianxing knew that the most critical moment had come, and carefully strengthened the Dan fires, so that they began to condense into Dan.

The key to the entire alchemy is at this moment, once it fails, all the previous efforts are lost, and everything has to be started again.

His spiritual power was facing depletion, and it had also reached its limit, so that he was completely overdrawing his soul power and began to complete the final condensation.

Chu Tianxing felt a burst of blackness in front of his eyes, knowing that refining the heaven-level spirit pill with his current strength was really too reluctant, and he had crossed the two great realms to refine the pills that could only be used above the fusion realm.

However, he knew whether he would succeed or fail at this moment, and suddenly bit the tip of his tongue and forced himself to wake up.

In the end, I poured all my energy into it, and the thing was done.

Call!

The Dan Furnace's Dan Flame suddenly skyrocketed, causing the fire to skyrocket to the maximum, completely engulfing the essence of medicinal herbs suspended there.

Chu Tianxing confirmed that the spiritual power had been fully consumed, and it was time to fight for willpower.

Seeing through the Danhuo that the mass of essence liquid gradually shrunk, and gradually condensed into a Dan type in the Danhuo, he was surprised that the first time he refined the Yin-Yang Mixed Yuan Pill, he actually refined three!

If he can succeed, he can not only get one Yin Yang Mixed Yuan Pill to save the Cloud Sky Frost, but also get two more as an additional harvest.

But now he has to be more careful, because if he makes a mistake, he will not be at all.

Little by little, he fought his mental power to control the fire, and let the three kinds of pills burn on the three pills that were about to take shape, which meant that he still had to concentrate on three uses now, and he couldn't be sloppy at all.

Boom!

Suddenly, the Dan furnace exploded, the lid of the Medicine King Furnace was blown open, and three golden lights shot out and wanted to run out!

Although they were only heaven-level elixirs, they already had some spirituality.

After Cheng Dan, he instinctively wanted to escape, and he didn't want to become something that other creatures helped heal.

Chu Tianxing had spent a lot of effort refining them, how could he let them escape now.

A strong pill did not hesitate to go down, because now there is no need to alchemy and there is no need to care.

It was to use the power of the wood system to reach out and grab the three elixirs towards them in the air.

In an instant, a huge wooden hand erupted, instantly grabbing two of them across a distance of more than ten meters, making them tremble and stop moving.

The other one was restless, and one of them ran away. Obviously, it is of the highest quality among the three elixirs.

Chu Tianxing, however, had better not let it run away, just by doing it himself. The figure disappeared in an instant and directly entered the state of nothingness, and the void walked quickly and appeared next to it at the moment when this elixir relaxed its vigilance, holding it firmly in his hand.

At this time, the three elixirs were successfully acquired.

Chu Tianxing also saw that the first two had actually reached the heaven-level top grade, which showed that the Medicine King Furnace had an amazing effect of improving alchemy.

Finally, when he looked at it, he found ......

"Immortal-level inferior grade?!"

Even if it's just a lower grade, it's a real immortal level, which means that this is an elixir!

This Yuntianshuang must be saved!

Chu Tianxing immediately thought so, and rushed to Yun Tianshuang and them as quickly as he could, just to use this immortal-level Yin Yang Mixed Yuan Pill to rescue Yun Tianshuang.

At this time, Yun Tianxue in the room was anxiously guarding next to the unconscious Yun Tianshuang, and Chu Lingling continued to inject ice spiritual power into Yun Tianshuang to fight against fire poison for her, preventing the two extreme poisons from breaking out in her body.

"Master!" Yun Tianxue saw Chu Tianxing coming in and immediately stood up excitedly and shouted at him, thinking that he had a way.

Chu Tianxing nodded at her and walked quickly to Yun Tianshuang's side, and immediately fed the immortal-level Yin Yang Mixed Yuan Pill in his hand to Yun Tianshuang, and used this elixir to reconcile the two extreme poisons in her body.

In an instant, half of Yuntianshuang's face was as red as fire, and the surrounding side was steaming with a blazing high temperature, while the other side was as white as ice, which directly made the frost freeze around the bed.

Seeing Yun Tianshuang's situation, Yun Tianxue immediately became nervous, because she really didn't want to lose her own sister again.

Chu Tianxing looked at Yun Tianshuang's state with confidence, and found that Yun Tianshuang would be a blessing in disguise if he didn't do it well this time, so that he would also get an unexpected new harvest.

Just as he was thinking this, Yun Tianshuang was unexpectedly windless, and floated up out of thin air, levitating above the bed.
