Ouyang Die's blood poison has returned!

After Tang Fan arrived, he immediately deployed the nine-star blood soul array, pulled Ouyang Die into the array, changed her bloodline, and detoxified her.

The room was filled with blood and the temperature was as high as a steamer...

He Yuexiang was waiting outside the door anxiously, with remorse written all over her face.

Although she does not have a deep relationship with Ouyang Die, she is her biological mother after all.

She felt even more uncomfortable when she thought that she had almost missed a big event.

He Lan understood her mood and comforted her: "Don't worry, with Tang Fan here, it will be completely cured this time!"

"Um!"

He Yuexiang also believed in Tang Fan's abilities and felt a little more at ease.

He Lan looked at He Yuexiang and suddenly sighed: "You really look like your mother..."

"What?"

"When she was young, she was very rebellious and played crazy..."

He Yuexiang blushed and pouted her lips in embarrassment.

Two full days passed before the blood energy in the room slowly dissipated and the temperature gradually dropped.

"mom!"

He Yuexiang rushed in desperately.

I saw Ouyang Die sitting on the bed, with a rosy face and looking much more energetic than before.

Tang Fan's blood hadn't dissipated yet. He opened his mouth and let out a breath of hot air. He looked at Ouyang Die and said, "It should be fine this time!"

Ouyang Die smiled and said: "I have already felt the powerful power of dragon blood..."

Tang Fandao: "In this way, you can practice the Blood Saint Sect's skills in the future, and you can teach Xiang'er."

Ouyang Die turned his head, looked at He Yuexiang with a loving look on his face, and said with a smile: "I told you last time, don't let Tang Fan get too tired..."

"Mom, I'm sorry..."

He Yuexiang hugged Ouyang Die and cried with joy.

"You guys can chat, I have something else to do."

Tang Fan couldn't bear to disturb this tender scene and quietly left.

Outside the door, He Lan grabbed Tang Fan and asked, "When do you want to leave?"

"My cultivation level is not very stable yet. Besides, I am in alchemy..."

Tang Fan suddenly remembered that He Lan was also a master of alchemy, and immediately said: "Godmother, I have something to ask you..."

Tang Fan took He Lan to the outside of the palace, told the scene he saw of the Dragon Emperor refining the pill, and asked: "Goddess, please help me analyze what part of his furnace pill went wrong...

…”

"this……"

He Lan frowned and thought deeply. After a long time, he said: "If it is not a problem with the method of refining the pill, then could it be a problem with the pill itself? For example, it cannot exist at all!"

Tang Fan said: "I have been deducing this eternal elixir for a long time. It should be possible to refine it, but it is too difficult!"

He Landao: "Could it be a problem with the alchemy furnace and... fire?"

"Alchemy furnace and fire?"

Tang Fan's heart trembled and he suddenly became enlightened.

"Think about it, since this elixir has eternal power, ordinary elixir furnaces and fires may not be able to support the power of this elixir..."

"That makes sense..."

Tang Fan nodded silently. He recalled the alchemy furnace used by the Dragon Emperor when refining alchemy. He thought that given his dignity, the alchemy furnace used must not be simple. Moreover, the alchemy furnace was not damaged after the failure, which showed that there was no problem with the quality.

Could it be fire?

When the Dragon Emperor made the elixir, he used the Nine Phoenix Divine Fire. Could it be that the divine fire cannot control the power of this elixir?

"Godmother, is there any fire for refining elixirs that is more powerful than divine fire in this world?"

He Lan looked stunned, thought for a long time, and finally shook his head.

"In my opinion, your divine fire is the most powerful fire..."

Tang Fan nodded silently. Ever since he witnessed the scene of the Dragon Emperor's failure in refining the elixir, he felt as if he was in a daze and could not let go of this matter.

He turned around and was about to leave when He Lan suddenly pulled him back: "By the way, I remembered a legend..."

"What?"

Tang Fan immediately stabilized his body.

He Landao: "I once heard someone say that alchemy masters in ancient times could turn their own Dantian into fire and use it to make elixirs. Because of their different attributes, there are Yin Fire and Yang Fire. The most powerful one is Yin Yang and Five Elements.

Pill fire!"

"Yin Yang Five Elements Dan Fire?"

"This is just a legend. I don't know if this fire exists, let alone whether it is stronger than the divine fire. But there is one thing..."

"It is said that this yin and yang five elements elixir fire circulates on its own and has the power of the five elements. Using this fire to make elixirs can increase vitality, stabilize the soul, and have the effect of resurrecting the dead!"

"The Dantian transforms into fire, circulates Yin and Yang, and enhances vitality..."

"If the eternal elixir you said can make people live forever, then the fire used to refine the elixir must also contain the power of the yin and yang cycle. Otherwise, relying solely on medicine and the spiritual energy of all things will not be enough!"

"That makes sense!"

Tang Fan's eyes flickered, but then he smiled bitterly and said: "Godmother, turning your Dantian into fire is equivalent to turning yourself into fire. Won't you burn yourself to death?"

"So, I am skeptical about this legend!"

"Yes, no matter what kind of fire the Dantian turns into, it is burning yourself!"

Thinking of this, Tang Fan became even more distressed.

He Lan advised: "Child, I think... you think too much. Please wait until you become a powerful person to think about these things. Maybe then you will understand."

Tang Fan nodded and walked out in despair, feeling suddenly at a loss.

Once upon a time, forming a golden elixir and refining an eternal elixir were his two major pursuits.

Now that he had achieved Purple Gold Perfection, he originally thought he could try to refine the Eternal Immortality Pill, but he didn't expect to find out after in-depth study that the reality was even further away from his imagination.

Could it be that I am going in the wrong direction?

Is it impossible for this eternal elixir to exist in the world?

"The dantian turns into fire, the yin and yang and the five elements of elixir fire?"

Tang Fan shook his head and could only try not to think about this matter and focus on his practice first.

"You godmother has some knowledge!"

Suddenly, the voice of the weapon spirit came from Tang Fan's mind.

"senior?"

"Theoretically, this yin-yang and five-element elixir fire does exist, and... to put it simply, you can think of it as the eternal fire!"

"real?"

Tang Fan was shocked.

"This...is this the eternal fire?"

"This fire circulates yin and yang, integrates the power of the five elements, replenishes the vitality of all things, and naturally... will never be extinguished, so it can be called an eternal fire!"

"this……"

Tang Fan breathed rapidly, clenched his fists tightly, and said after a long time: "If there is eternal fire, then there will definitely be an eternal elixir. Once life can cycle through yin and yang, it will be immortality!"

"Theoretically...that's it!"

"It will definitely work!"

"Theoretically..."

The voice of Qi Ling is a little strange.

Tang Fan heard something was wrong in his voice, and seemed to have thought of something, so he asked: "Senior, if Dantian can really turn into fire, then the Dragon Emperor must also know why he... didn't succeed?"

"Actually, you didn't realize that although he failed at first, he had already added his own fire when refining the elixir!"

"Is it?"

"It's just that the fire in his Dantian is Yang fire. It doesn't belong to the Yin Yang and Five Elements Dan fire, so it's not perfect enough..."

"Then why didn't he cultivate the yin-yang and five-element elixir fire?"

"this……"
To be continued...
