It was not known how long it had been since they last looked at the date when they knew they had been here for half a year, and how long had passed since then.

Chen Ruoxi reluctantly looked at those spirit beasts again, and then left the Dan room with Fang Heyu. And the stone door of the Dan room slowly closed by itself, what they didn't know was that after the stone door was closed, the Yuan Force cages and spirit beasts that were originally in the center of the Dan room slowly disappeared.

At the moment when the stone door was closed, the two of them had not yet taken a step forward, only to feel a blazing breath coming towards them, the two were startled, and hurriedly sacrificed the flying sword, thinking that there was another test, but the danger did not appear, and the two of them suddenly found that a large tripod appeared in the center of the passage.

The whole body of the big ding is fiery red, exuding a blazing high temperature, and the body of the ding is engraved with four big characters "Xianyuan Medicine Furnace". Fang Heyu shouted: "This is, the medicine furnace, I'll just say, how can there be no medicine furnace in this Dan room, it's actually placed in the passage, this is really incredible." ”

Chen Ruoxi said: "Brother Yu, is this medicine furnace used for refining medicine?"

"That's right, Ruoxi, do you know why we could only refine liquid drugs before? First, our cultivation is too low, and secondly, because there is no medicine furnace, if we can refine Zhaoyuan Dan or even Juyuan Dan, the effect is much stronger than Zhaoyuan Liquid Juyuan Liquid. ”

Chen Ruoxi said happily: "Then hurry up and put it away, use the space ring." ”

Fang Heyu smiled bitterly: "The temperature of this medicine furnace is too high, I'm afraid that the ring will be broken, don't worry, observe it for a while." ”

The temperature of the Xianyuan Medicine Furnace is indeed ridiculously high, with the cultivation of the two of them, even if they are wearing battle armor and protecting their bodies with True Qi, they all feel a little scorching, thinking that the temperature of this medicine furnace has reached a high temperature of several thousand degrees.

Fang Heyu activated his true qi, protected his body, and then slowly walked towards the medicine furnace, the flames in the medicine furnace turned crimson, and swept towards the inside of the medicine furnace with his divine sense. Who knew that as soon as the divine consciousness penetrated into the inside of the medicine furnace, it was directly burned, and even Fang Heyu's spiritual power flickered, if he hadn't opened up the spiritual sea, it was estimated that his spirit would have been hit hard.

"What a terrifying flame, it seems that this is actually a kind of spiritual fire of heaven and earth, I think about it......"

Fang Heyu began to check his Easy Heart Sutra, and sure enough, he found a crimson Heaven and Earth Spiritual Fire, the name was Red Refining Immortal Fire, it turned out to be Immortal Fire, and Fang Heyu's pupils also shrank sharply.

Immortal fire is much more advanced than spiritual fire, and it is the best fire for refining pills and various spiritual treasures, but it is difficult to refine.

The Red Refining Immortal Fire ranks fourth among the thirteen immortal fires recorded in the Xiaoyao Heart Sutra, which is relatively high, which shows how high its quality is, and the fire of the Red Refining Immortal Fire is relatively mild, and it is relatively easy to be refined, of course, this refers to relative to other immortal fires, after all, if you want to refine the immortal fire, no matter which one is a very difficult thing.

"Ruoxi, this turned out to be a kind of immortal fire, I really didn't expect it, I really don't know what kind of existence the owner of this immortal yuan tomb is, and there is such an anti-heaven level fire. ”

"Brother Yu, can't you collect it?"

"No, I dare to conclude that if you forcibly collect it, the space ring will be burned directly, and you must refine the immortal fire first. ”

Chen Ruoxi said worriedly: "Brother Yu, with our cultivation, we can refine the immortal fire?"

"I don't know, but I dare to conclude that if this Immortal Yuan Medicine Furnace and Red Refining Immortal Fire appear here, then it must be charged for us, and it will definitely be used in the later tests, if we don't collect it, we will probably not be able to leave here." ”

"Alas, in fact, I also know this, everything arranged here is meticulous, if we don't collect it, it is estimated that we will not be able to pass the test later. ”

Fang Heyu took a deep breath and said, "Try it anyway, if this is scared, how can we still cultivate to the supreme realm?"

"Okay, just fight, I will protect the Dharma for you, and if you fail, I will die for you. ”

Fang Heyu looked at the girl beside him with a smile and said, "Ruoxi, we won't die, I will definitely succeed, even if it is for you, I must succeed." Fang Heyu's tone revealed an extremely firm confidence.

Chen Ruoxi nodded firmly, but she had already made up her mind, if Fang Heyu died, she would never live alone. Of course, Fang Heyu also saw her thoughts from her eyes, strengthened her confidence, and warned herself that no matter how painful it was, she must survive and succeed.

Fang Heyu took out a few bottles of Vitality Pill and Yuansheng Pill from the space ring, these two medicines are for healing and restoring true qi respectively, they are both commonly used medicines, and the effect is also quite good, he handed it to Chen Ruoxi, and said: "Ruoxi, when I refine the Red Refining Immortal Fire for a while, it is estimated that I will not be able to spare my hands to take medicine, you see my reaction, I blink my right eye and you give me the Vitality Pill, and you give me the Yuansheng Pill in the blink of my left eye, remember?"

Chen Ruoxi looked at the bottles of medicine in his hand and said, "Well, I understand, Brother Yu, you must be careful." ”

"Don't worry......"

Fang Heyu sat down cross-legged in front of the medicine stove, activated his true qi, adjusted his state to the best, and then stretched out his hands and stuck them on the medicine stove.

Zla, the high temperature scorched Fang Heyu's hands, directly turning jet black, Fang Heyu frantically urged the true qi, directly injected into the medicine furnace, forcibly sucking the internal red refining immortal fire.

The Red Refining Immortal Fire was worthy of being an immortal fire-level existence, and his true qi was directly burned away. Fang Heyu took a deep breath, and the inner pill in his body swirled, and the rich true qi frantically poured into the medicine furnace.

After all, the Red Refining Immortal Fire was not self-conscious, and the blazing high temperature only subconsciously scorched Fang Heyu's True Qi, but Fang Heyu's True Qi was too fierce, and the Immortal Fire did not burn all the True Qi at once, and the next moment, Fang Heyu screamed violently, controlling the True Qi to pull the Red Refining Immortal Fire directly out of the medicine furnace.

Woo...... , The entire passage was suddenly filled with crimson light, and the temperature also rose instantly, Chen Ruoxi used his true qi on the side to protect his body, but he already felt the terrifying high temperature.

A crimson flame was dragged out of the medicine furnace by Fang Heyu like this, and then Fang Heyu actually opened his mouth directly and swallowed the flame.

Hum...... With a muffled snort, Fang Heyu's body directly turned red, and his whole body was like a boiled crab, and it exuded a terrifying heat wave, and even the golden battle armor on his body began to show a hint of melting.

Fang Heyu's feeling was even more painful, under the burning of all his insides, he only felt that his muscles and veins and bones had even begun to burn, and the Red Refining Immortal Fire was frantically running around in his body, trying to find a way out to get out, causing extremely serious burns to Fang Heyu.

Neidan's rotation has reached the extreme, and the true qi is frantically outputting to protect his body from being completely destroyed by the immortal fire, and at the same time, he has to capture the immortal fire in his body for refining.

Although the immortal fire is not conscious, it also senses danger, and it is obvious that someone wants to refine it so that it will not be free. Feeling this danger, the movement of the immortal fire became even more crazy, and the true qi in Fang Heyu's body had already consumed seventy-seven eighty-eight before he could do anything with tea.

Fang Heyu hurriedly blinked his eyes, and Chen Ruoxi hurriedly took out a vitality pill and a Yuansheng pill for Fang Heyu to eat.

With the assistance of the elixir, Fang Heyu was a little more relaxed. The Vitality Pill exuded a hint of coolness, and it quickly melted into a medicinal liquid, beginning to moisturize his burned tendons, while the Yuan Sheng Pill quickly restored his true qi, making the inner pill spin faster and the true qi output stronger.

The Red Refining Immortal Fire felt Fang Heyu's True Qi suddenly become stronger, and began to flow more wildly, Fang Heyu endured the burning pain, and began to use his True Qi, capturing the Immortal Fire, while blinking his left eye again.

Chen Ruoxi hurriedly fed him another Yuansheng Pill, and then the true qi in Fang Heyu's body became a little stronger again, and he quickly found the immortal fire scurrying in his body, directly controlled it, and began to refine.

The immortal fire was surging wildly, but under the effect of the continuous Yuansheng Pill, Fang Heyu's true qi was endless, never exhausted, and it became more and more vigorous, wrapping the red refining immortal fire almost unable to move at will.

Controlling the True Qi, Fang Heyu slowly moved the Red Refining Immortal Fire to the top of the Inner Dan at his dantian, and then used the rich True Qi emitted by the Inner Dan to completely suppress the Red Refining Immortal Fire.

Finally stabilized temporarily, Fang Heyu blinked his right eye, and then Chen Ruoxi gave him another vitality pill. The burns in his body began to recover rapidly under the action of the Vitality Pill, and Fang Heyu mobilized the spiritual power of the Spirit Sea and began the final refining process.

The so-called refining immortal fire is to plant one's own spiritual imprint on the immortal fire, so that the immortal fire will never back, let alone burn oneself again.

The Red Refining Immortal Fire felt the crisis, and once again surged wildly, almost breaking free from the shackles of the Inner Dan, but fortunately, Fang Heyu took a Yuansheng Pill again, and with the support of strong True Qi, this did not let the Immortal Fire break free from the shackles, and then injected spiritual power, and began to brand his own spiritual imprint on the Immortal Fire.

The terrifying high temperature of the immortal fire was still the same, even if it was wrapped in true qi, it still burned Fang Heyu's spiritual power instantly, this kind of immortal fire, as if it could burn everything, whether it was spiritual power or true qi, it could not be spared.

Fang Heyu didn't try again, but controlled the true qi and began to slowly compress the immortal fire, so that the immortal fire completely stabilized.

I don't know how long it took, and I don't know how many Yuansheng Pills I ate, the Red Refining Immortal Fire finally calmed down completely, and there was no longer the slightest intention to resist.

Only then did Fang Heyu remobilize his spiritual power and try to re-brand, and sure enough, the immortal fire no longer resisted, this unconscious immortal fire seemed to have accepted his fate, allowing Fang Heyu's spiritual power to invade easily.

Although the high temperature still made Fang Heyu's spiritual power jump directly to pieces, under his continuous efforts, the spiritual power was gradually imprinted on the Red Refining Immortal Fire, and at the same time, the true qi wrapped around it also merged together, forming a rare fusion state of immortal fire true qi and spiritual power.

After eating another vitality pill, Fang Heyu continued to heal his injuries, and while he was also concerned about the refining of the immortal fire in the dantian. The immortal fire was completely silent, which made his refining much easier, and he never encountered a dangerous situation again.

I don't know how long it took, Fang Heyu's spiritual sea suddenly turned red, and in his consciousness, a crimson flame suddenly appeared, which was the flame of the Red Refining Immortal Fire.

And at his dantian, above the inner dan, there was a thumb-sized crimson flame quietly suspended there, and no longer released the high temperature, Fang Heyu felt that as long as he had a thought, he could control this flame for his own use.

Succeeded, at this time, Fang Heyu knew that he had succeeded, and then he smiled and said, "Ruoxi, it's finally over, give me another vitality pill." ”

There were still a large number of burnt injuries in his body, Fang Heyu had to take another vitality pill, and then use his true qi to start healing, while also observing the red refining immortal fire in the dantian.

After confirming that there was no problem, Fang Heyu began to heal his injuries with all his strength, and after eating three more vitality pills, his injuries could be regarded as completely recovered, which showed how terrifying the damage caused by the previous Red Refining Immortal Fire was.
