Immediately, Ning Tianxuan's voice disappeared, which made Lin Feng puzzled, not understanding what this Fan Dan was.

So he returned to the Divine Soul Space again and asked, "Senior Ning! What is this Van Dan? Why are there any other five products, and what is it exactly? ”

Sure enough, soon, Ning Tianxuan's voice sounded again in the Divine Soul Space.

"Pills can be divided into four categories according to grades, namely: Fan Dan, Ling Dan, Xian Dan and Shen Dan, each grade is divided into nine grades, such as a first-grade Vandan, a second-grade Vandan, a third-grade Vandan, a fourth-grade Vandan, a fifth-grade Vandan, a sixth-grade Vandan, a seventh-grade Vandan, an eight-grade Vandan, and a nine-grade Vandan."

"The marrow cleansing pill you want to refine now is a second-grade Fan Dan, which is stronger than ordinary pills, at most it is just a marrow cleansing body, and the others have no effect, and it is not bad for you to practice with this second-grade Fan Dan."

Lin Feng nodded, Ning Tianxuan was right, he was just a beginner in alchemy.

The Myelin Cleansing Pill is not a very high-grade elixir, so it is better to refine some, otherwise it is impossible to refine it successfully before.

After retracting his divine sense, Lin Feng began to concentrate on refining the elixir.

If you want to activate the Nine Heavens Fire Separation Array, you must release the True Yuan inside the Tianzun Divine Ding, and only when the number of True Elements reaches the upper limit of a primary formation can the Nine Heavens Fire Separation Array be activated.

The triggering of the mortal array was still relatively easy, and with the true yuan he possessed now in the ninth layer of qi refining, it was barely okay.

In this way, Lin Feng activated the true elements in his body, and then slowly released these true elements into the Tianzun Divine Ding, and the Nine Heavens Fire Formation was also activated at the same time.

The power possessed by the Nine Heavens Fire Array was very powerful, and once it was activated, it could not be stopped without refining the elixir.

Either the true element in the caster's body can be drained, or it can be stopped, but this will cause great damage to the caster's body, which is not what Lin Feng wants to see.

The elixir of refining the myelin cleansing pill was thrown into the Tianzun Divine Ding, and the Nine Heavens Fire Array was also running at this time, and the strong fire energy continued to flash from the Tianzun Divine Ding, and the elixir was turned into elixir liquid one by one, and then it was continuously refined and fused in the Tianzun Divine Ding.

In this way, a whole few days passed, but Lin Feng didn't even move at all, as for Scar, the others were waiting outside the room very anxiously, and they didn't know what was going on inside, they only knew that the temperature in the room was very high, and they couldn't get close even if they wanted to, let alone Lin Feng who was inside.

"Big brother! What are we going to do? Do you want to open the door? Daohai asked at this time.

"Wait! I believe that Lin Shao will come out soon, as for this room, someone still has to be sent to guard it, but don't let anyone else enter this room, with Lin Shao's strength, even if the warmth is so high, there will definitely be nothing wrong. Scar thought for a moment and said.

"Oh well! It's just that this room doesn't explode, the power of this explosion will hurt even if Lin Shao is strong. Daohai said at this time.

Scar didn't speak, because he knew that even if he said it, Daohai wouldn't understand Lin Feng's strength, but he had watched Lin Feng come all the way, and he also knew that he was strong, which was why he had so much confidence in Lin Feng.

In the room, Lin Feng was still refining the pills, and the Cleansing Pill had already refined a lot, and it was time to change to another pill, which was the Zhuji Dan.

Zhuji Dan is still a little difficult for Lin Feng today, after all, he is a fourth-grade Fan Dan, and it is still a certain difficulty for him now.

The difficulty is there, but it's not that it can't be refined, just after Lin Feng packed all the marrow cleansing pills into the jade bottle he had prepared in advance, he directly took out a low-grade spirit stone and absorbed it directly.

Sure enough, after refining so many marrow cleansing pills, it was such a simple matter to refine the Zhuji Dan again, and the true yuan in his body was already insufficient, so he took out the spirit stone to absorb it.

But it was obvious that this grade spirit stone didn't have much effect at all, he simply took out a medium-grade spirit stone and absorbed it, and it didn't take long for his depleted dantian and the true yuan in the major meridians to be replenished again.

Seeing all this, Lin Feng smiled, and the Nine Heavens Fire Formation also activated again, and because of the high quality of the True Yuan this time, the quality of the pill he refined was not just comparable to it.

The refining time has also been greatly changed, and the Zhuji Dan came out one by one, and the rich medicinal gas made Lin Feng feel relaxed and happy when he smelled it.

Originally, there wasn't much when he reached the ninth layer of qi refining, but after smelling so much of the medicinal fragrance of the Zhuji Dan, Lin Feng unexpectedly found that his cultivation realm of the ninth layer of qi refining began to loosen, which immediately made him happy.

However, he was not in a hurry to break through, with his current strength, he had already cultivated fast enough, and the most important thing in cultivation was the cultivation of the state of mind, that is, the realm of the divine soul.

Only when the Divine Soul Realm has been raised to a certain level can he quickly improve his cultivation again, but for Lin Feng, this improvement in cultivation has no effect on him at all, so he plans to break through.

The newly refined Zhuji Dan was directly put into his mouth, and the pill melted in his mouth, bursting out with unparalleled power, and the medicinal power directly turned into a potion and flowed directly into Lin Feng's dantian position.

Rumble!!

Lin Feng's momentum exploded in an instant, and the majestic and infinite momentum continued to impact the surrounding space, which made the already very hot room crack all at once.

But due to the good materials, it is impossible for this room to be broken all of a sudden, but it is not much worse.

After the medicinal power was dissolved, the medicinal power continued to impact the major meridians and dantian of Lin Feng, repeatedly impacting, in order to break through to the foundation building period.

The ninth layer of qi refining and the foundation building period were originally a watershed, how could it be so easy to break through, even if because of the relationship between the foundation building pill just now, Lin Feng's realm had already loosened, but there was still a little gap from the real breakthrough.

The medicinal power of Tsukidan was still filling Lin Feng's entire body, as if there were thousands of knives slashing through his body.

It's painful, but it's unbearable.

Impacting the major meridians over and over again, the pain is not at all understandable to ordinary people.

Gradually, the bottleneck that had been broken through began to loosen continuously, and the majestic momentum continued to emanate from his body, as if the end was coming.

The momentum also continued to pound against the surrounding walls, which were shaky as if they could collapse at any moment.

Suddenly, the room suddenly exploded, and the powerful momentum continued to impact out, and the scar people who were waiting outside were directly bounced out, and then a figure rushed out of the room directly, and the speed of the figure was extremely fast, and it came to the side of the scar people in an instant.

Then, with a wave of one hand, the momentum that had erupted from him disappeared without a trace in an instant, as if it had never appeared.

This person was none other than Lin Feng, who had just come out of the room.

He couldn't control his strength well because he had just broken through the foundation building period, so he let the momentum directly break through the room, and even directly injured Scar and several people, which made him feel guilty.

So when he saw the appearance of a few people, Lin Feng directly took out the Pulp Cleansing Pill and put it in their mouths one by one, with the Pulp Cleansing Pill, there were no injuries on their bodies, and it could also improve their physique, so that they could better cultivate.

These are in a coma, of course, they don't know.

The medicinal effect of the Cleansing Pill was very amazing, and it didn't take long for them to stand up again like a nobody, looking at each other's incredible gazes, Scar finally set his eyes on Lin Feng, and said in surprise: "Lin Shao! Have you refined your elixir? ”

"It's done! And each of you has taken one, do you feel any changes in your body? Lin Feng said with a smile.

"What's going on? How did I become a black hill person? ”

Daohai looked at himself in the reflected light of the glass blankly, felt the uncomfortable appearance in his clothes, and immediately untied it, and saw the thick layer of black substance on his skin.

"What the hell is going on?" Scar also looked at his body and his face in disbelief, and he was surprised to find that his original big scar was gone, and the skin that was born was brand new.

"Lin Shao! What the hell are we going on? ”

Not only did Scar and Knife have changed, but several other people present have also changed to varying degrees, and like Scar Knife, their bodies have also undergone major changes, making his clothes even dirtier.

"What are you still standing here? Don't give me a proper wash of your body. ”

As soon as Lin Feng ordered, the people present disappeared in front of each other's eyes and rushed to the bathroom, where there was a way to take a shower.

All of a sudden, there was a long queue in the bathroom, and ten of them were constantly crowded to wash themselves, but in the end, they made an exclamatory sound one by one, and they never thought that when they had just washed it, the original black skin like ink suddenly turned into baby-like skin.

So tender skin? I even have such skin, Scar is sighing constantly.

As we all know, as long as it is a person who mixes with the underground forces, he will always deal with the sun, and his arms and feet will be very dark for a long time.

"What the hell is going on?"

After everyone came out again after taking a shower, they found each other's characteristics, these people had incredible expressions written on their faces, and they didn't know that such a thing would happen, they were actually rejuvenated.
