The medicine pod above the fire well in the Dan furnace kept tumbling, and there was terrifying spiritual power surging inside. The elixir that had not been completely refined released a rolling medicinal power, raging the entire Dan furnace.

Ning Yu opened every pore on his body, frantically absorbing these medicinal powers, and refining his physical body.

After a while, a faint golden light was emitted from the surface of his body, and the energy fluctuations in his body were not much worse than that medicine tripod.

The old man's eyes were shining, and his eyes were burning when he looked at Ning Yu.

Dongfang Yi saw that Ning Yu was cultivating, and he also seized the opportunity to cultivate his Nine Kills Battle Technique. After a while, his body also erupted with rolling energy fluctuations, which was extremely terrifying.

Lu Xiunian was speechless, these two people really regarded this place as their retreat. But this is a rare opportunity, he didn't dare before, but now the old man doesn't seem to object, he also put aside distracting thoughts and cultivate.

The old man kept nodding his head, as if pleased with the performance of the three men. Then he didn't care about anything else and went all out to refine the Dragon Xuandan.

In this way, after a week passed, refining the Dragon Xuandan had entered the most critical stage.

At this time, even the old man was sweating on his forehead and began to struggle.

"In alchemy, the most important thing is spiritual power, only if the spiritual power is strong enough can the fire be accurately controlled. If the heat or fire control of a furnace of pill is not good, the grade will be reduced, the pill will be wasted, and the furnace will be fried, and the pill will be broken and killed. The old man controlled the pod to turn over and over and adjust the temperature inside the pod.

But at this moment, there was a sudden explosion from inside the medicine tripod, which shook the medicine tripod violently, and the surging spiritual power erupted from the medicine tripod, raging the entire Dan furnace.

Ning Yu and the others, who were cultivating, were all awakened by the explosion, and looked at the old man with a shocked face.

"It's going to blow up the oven, get out of here!" said the old man, his face flushed. He was now trying to suppress the violent power inside the pod.

Ning Yu frowned slightly, his divine sense penetrated into the medicine tripod, and found that there were nine golden pills in it that were constantly rotating, exuding a terrifying aura. There was dragon qi lingering on the surface of that elixir, and it was not ordinary at first glance.

Originally, there were ten, but one of them had been blown up, and even the remaining nine could be blown up at any time.

"Old man, the temperature inside the medicine pod is too high, the medicinal power is too violent, hurry up and open the lid of the pod, I will throw a blue ice flower into it to neutralize and neutralize, quick!" Ning Yu shouted at this time.

Lu Xiunian and Dongfang Yi were all frightened when they heard this, this Ning Yu actually wanted to teach the old man how to do it!

"You have a blue ice flower in your hand?" the old man's eyes flashed with excitement.

"Don't talk nonsense, if you don't want this furnace pill to explode, hurry up and open the lid of the tripod!" Ning Yu was extremely anxious, cracks had already appeared on the surface of the nine dragon pills, and if they didn't neutralize the temperature and medicinal power inside the medicine pill, they would explode.

Bang dang!

The old man was very decisive and lifted the lid out. Ning Yu quickly pulled out a blue ice flower and threw it in.

Burst!

The Blue Ice Flower was the coldest elixir, and as soon as it was thrown into the pot, the temperature inside dropped sharply, and the violent medicinal power also turned into blue flames and gushed out.

"It's now, go back to the furnace, Ning Dan!" Ning Yu burst into tears.

Rumble!

The old man closed the lid again, and then controlled the medicine tripod to leave the fire well, constantly flying in the air, causing its temperature to drop and condense the Dragon Xuandan.

Burst!

The old man flipped the medicine pod for a while, and then placed it heavily on the ground, and suddenly the light gushed out from the medicine pod, and then the fragrance of the secreting medicine filled the entire Dan furnace.

"It's a success!" Lu Xiunian and Dongfang Yi all widened their eyes, and their eyes were full of excitement.

The old man was out of breath, this one was so thrilling that it almost exhausted all of his spiritual power.

"You kid, you're a little capable!" the old man looked at Ning Yu, his eyes full of admiration.

"Average!" Ning Yu didn't seem to know how to write the word modesty, which was maddening.

The old man was so angry that he blew his beard and glared, but this time Ning Yu helped him a lot, and he didn't care. Then he walked over and opened the lid of the tripod, and suddenly a surging light poured out of the tripod.

When the old man saw the dragon pill inside, his pupils dilated violently, because there were several blue marks on the surface of the nine golden dragon pills, which should have been formed by the medicinal power of the blue ice flower.

"It's such a powerful energy fluctuation, the grade is actually a fourth-order lower grade pill, it's too shocking. The old man was unexpected, and was so surprised that he was stunned on the spot.

Ning Yu and the others also rushed over to watch at this time, their faces were also full of shock.

"Old man, those who see it have a share, each of them will give us one. "Ning Yu's eyes are extremely hot, that Long Xuandan can at least make his golden body rise from the second to the third realm.

"Are you supposed to steal something?

"What a slam on the door!" Ning Yu said angrily.

"Don't say a word!" Lu Xiunian pulled Ning Yu, he was really afraid of angering this old man, and everyone would have good fruit to eat.

"Hehe, this elixir has to be handed over to those people anyway, it's better to be cheap than cheap for them!" The old man smiled, and then threw a Dragon Xuan Pill for Ning Yu and each of them, and said, "Hurry up and refine it, otherwise even I won't be able to protect you!"

After saying that, he floated out of the Dan furnace and disappeared.

Ning Yu and the others got Long Xuandan, and they were so excited that they wanted to shout.

"Without further ado, I'm going to start refining!" Ning Yu couldn't wait any longer, so he directly sat down in this Dan furnace and swallowed that Dragon Xuan Pill.

This Dan furnace is refining medicine all year round, and the spiritual energy in it is abundant, which can just be used for cultivation.

Dongfang Yi naturally refused to let go of this opportunity, and directly sat down to refine that Dragon Xuandan.

"Damn, you guys...... Is it new?" Lu Xiunian had the urge to vomit blood, and now he has become the follower of these two. However, it was Ning Yu's credit to get the Long Xuandan, so he didn't have any complaints, and he also sat down to refine the Dragon Xuandan.

After Ning Yu swallowed that Dragon Xuandan, he felt that his body was about to explode, that Dragon Xuandan, which was very terrifying, and as soon as the medicinal power dissolved, it almost incinerated his body.

But this is the only way for him to transform, and he has long expected it in his heart, so he has been stoic.

"You must succeed, I won't give up!" Ning Yu kept roaring, frantically suppressing the medicinal power in his body and making it wash his body.

At the same time, he continued to deduce the Heavenly Opening Technique, and the Heavenly Stepping Fist and the Heavenly Stepping Seal continued to blast out, shaking the Dan furnace violently.

At this time, his head was smoky, his whole body was hot, and every pore on his body was steaming. But at the same time, the residue in his body is also discharged through his pores, and the flesh completes the metabolism of the old and the new, washing the marrow and changing the bones.

Poof!

A week later, all the medicinal power of that Dragon Xuandan dissolved, it was like a star bursting in his body, and the raging spiritual power was like a sword rampaging through Ning Yu's body, impacting every cell of him.

Yes......!

Ning Yu let out a miserable scream, and the power of Long Xuandan's medicinal power exploded in full force, which was his most painful and dangerous moment.

Because his dantian was broken, those medicinal powers could not be gathered and converted into the aura needed by the human body to buffer the pain, so he could only let the violent medicinal power directly wash his body, the pain was direct, and the process was cruel.

"Suppress!" Ning Yu's face was hideous, he was spurting blood from all his orifices, but he directly suppressed that inhuman pain with his own will, which was very crazy.

In this way, a month later, Ning Yu successfully refined the Dragon Xuandan, and the strength of his physical body was also promoted from the double of the golden body to the triple of the golden body.

"Hehe, if I use the Heavenly Seal again at this moment, I will definitely be able to slap Ye Tian to death, if his cultivation stagnates!" Ning Yu stood up, feeling the changes in his body, full of confidence.

Rumble!

Ning Yu slowly poked out a punch, this punch was not fast, but it distorted the void in front of him, and a violent force exploded from his fist, shaking the entire Dan furnace swaying.

"The power of the Sky Stepping Fist also grows stronger with the strength of my physical body, which is good. Ning Yu was extremely excited, and he was more and more full of expectations for the future.

At this time, Ning Yu looked at the side, Dongfang Yi was still in the middle of his stay, but Lu Xiunian had disappeared.

Lu Xiunian was originally a mid-stage cultivator of the Yu General, so it was not risky for him to refine that Dragon Xuandan. But Dongfang Yi's realm was only in the early stage of Yu Jiang, so the pain he endured was the same as Ning Yu's.

Ning Yu didn't bother Dongfang Yi, because his divine sense covered the past and knew that the most dangerous period of the other party had passed, and there would be no problem.

Then he walked out of the Dan furnace and found that it was dark outside, and Lu Xiunian had fallen asleep, and the old man was nowhere to be seen, and he couldn't help but show a weird smile on his mouth.

"The night is dark and the wind is high, it is the time when I steal chickens and dogs!" Ning Yu turned into a streamer of light and ran towards the medicine garden.

His targets were all those high-grade elixirs.

"It's honeysuckle!" Ning Yu came to a valley and saw at a glance that there were more than a dozen honeysuckle flowers in the center of the valley. This honeysuckle is a fourth-order low-grade elixir, which is very helpful for cultivating the physical body and can strengthen people's physique.

"Hehe, offended. Ning Yu was so excited that he almost raised his arms and shouted, and then according to his previous method, four or five flowers were picked from each honeysuckle, which was definitely a great creation in total.

After picking the honeysuckle, he visited many places again, and the harvest was abundant.

Of course, he didn't dare to go too far. For example, if there are three flowers on an elixir, he will only pick one, otherwise it will be easy for people to find out. Besides, he planned to slowly plague this medicine garden.

Ning Yu felt that he was about to leave tonight, but at this moment, his divine sense found a place where the aura was a little too much, so he rushed over quickly.

"There is a spring here, and it is a living spring, and although the spring water in it is not as exaggerated as the spiritual water I get, it is also rich in spiritual energy. Also, the elixirs around here are all third-order and upward, which means that this spring is not ordinary. Ning Yu found that the bubbling aura of the * spring was bubbling from the spring, and he was happy in his heart, so he took off his clothes and jumped in to take a bath without saying a word. Anyway, there is no one here, he has just refined that Dragon Xuandan, and the surface of his body is full of residue and dirt discharged from his body, so he can use the spring water here to wash it well.
