"The first-grade Flame Explosion Pill refined by others will kill the enemies of the swordsman realm at most. What I refine is that even the swordsman can be blown up to death. ”

Chu Feng has absolute confidence in his alchemy skills.

Refining the Flame Burst Pill, the previous steps are no different from refining the Burning Pulse Pill. It's just that after it becomes a pill, it needs to depict the fire pill pattern on the pill for secondary refining.

Under Chu Feng's Danzun level, the medicinal materials in the Dan furnace were quickly refined into Burning Vein Pills.

There were three of them, each of which was three times the size of the normal Burning Pulse Pill.

And it has to be firmer.

"It's not bad, the next thing to do is to carve the fire pill pattern on the pill. ”

"If it was the previous life, I could only depict it with blood. In this life, there is no need to be so troublesome, directly manipulate the Jiuyang fire to portray, and the effect is better. ”

Chu Feng condensed and controlled the Jiuyang Strange Fire, which was revealed at his fingertips, condensing into a line of fire.

Then in the Dan furnace, he carefully carved the fire pill pattern for the three pills.

There are a total of nine types of Dan patterns, the most common and the simplest is the Five Elements Dan pattern. Including five kinds of gold, wood, water, fire, and earth. The remaining four are the more advanced wind, thunder, Taiyin, and Sun Dan patterns.

In Chu Feng's previous life, he comprehended a total of eight Dan patterns, but he was left with the last Sun Dan pattern that he did not comprehend.

I saw that Chu Feng was manipulating the line of fire formed by the Jiuyang Alien Fire, and carved a series of mysterious lines on the surface of the pill. They combine and then form a complete rune.

Buzzing~!

At the moment when the fire rune was completed, the entire pill actually trembled, making the sound of bees flapping their wings.

A magical scene appeared, and the strange fire under the Dan furnace was actually triggered, and it kept running upward. They seemed to want to converge towards that pill.

"It's cool to have a different fire!"

Chu Feng showed a smile of joy, if he wanted to change in his previous life, he could only use his own blood to portray the Dan pattern. Not only is it painful, it has a great loss of sperm and blood, but it is also prone to mistakes.

Now he controls the Danhuo to depict, which is accurate, simple, and efficient, and does not need to consume a drop of his own essence and blood.

It's really good.

It only took about half an hour, and all the three Burning Pulse Pills were depicted with the Fire Pill pattern. They kept trembling, causing the fire below the Dan furnace to become more active.

Chu Feng closed the lid of the furnace, controlled the ground fire, and carefully carried out the secondary refining.

This process has to be done slowly, and if you rush it, you will most likely blow up the oven. It's not uncommon to blow yourself up.

......

In the Dan room next door where Chu Feng was, the one who was controlling the Earth Fire Alchemy Pill was a majestic old man with white eyebrows and white hair, who looked quite old. However, the old man's face was ruddy, and his eyes were even brighter.

If Xie Bing and Niu Danshi saw this old man, they would definitely salute respectfully.

Because he is the dean of Dandao Academy - Ge Wanfu.

Even in the royal capital, it is quite famous.

Just as Chu Feng had finished carving the first fire rune, the old man noticed the abnormality. Wait for Chu Feng to engrave all the three pills into the fire runes. This is terrible, and the Dan room next to it has also been affected.

The earth fire that Ge Wanfu was manipulating, like a bull in estrus, suddenly smelled the Dan room next to him, with the smell of a cow.

They scurried in the direction of the Dan room where Chu Feng was.

This also caused a lot of trouble to Ge Wanfu, and he couldn't hold it down. There were even several times when it almost led to the failure of Ge Wanfu's alchemy.

"Who is the alchemy next to you? Why did you make such a big move?"

Ge Wanfu was secretly guessing, he was very curious, it was the teacher of the academy who was so powerful. It was able to cause the fire in his Dan room to be abnormal.

If it weren't for the pill that Ge Wanfu was refining, it was very important, he would definitely personally investigate it and see what the pill room next to him was doing.

There was such a big commotion.

This situation lasted for about an hour before it slowly returned to normal.

Call~!

Chu Feng also let out a long breath of turbidity, raised his sleeve and wiped the sweat from his forehead. Even through the Dan Furnace, he could feel a burst of extremely dangerous aura, emanating from it.

Refining the Flame Burst Pill is very dangerous. If there are conditions, Chu Feng will definitely do enough precautions.

Right now, he's starting from scratch and doesn't even have the simplest set of armor.

If it really exploded, he would have to be seriously injured if he didn't die.

The only thing that can be done is to be careful and be careful to control the risk to the minimum.

Fortunately, God favored him and let him succeed without danger.

Uncovering the lid of the furnace, Chu Feng looked at the three Flame Burst Pills in surprise. Their entire bodies turned crimson, and the fire runes could be faintly seen manifesting on the surface of the pill.

At this point, it is basically refined. However, there is one last step that needs to be completed in order to be revealed.

That's Bundan.

Ordinary pills, Feng Dan is just sealing wax. Seal it with wax to prevent the loss of medicinal properties.

Fu Dan's Feng Dan is completely different.

Just like drawing a talisman to form a talisman, after the talisman is refined, it is necessary to seal the vital fire rune.

Chu Feng pinched the magic trick in his hand, and his fingertips once again showed the Jiuyang Strange Fire, separated a trace, and landed on one of the Fu Dan. It writhed like an earthworm, and then sealed the fire rune on the pill.

When Chu Feng sealed all the three Flame Explosion Pills in accordance with the law, this was the end of the process.

It's much harder to detonate them now. That dangerous aura has also faded a lot.

"Very good, with these three Flame Burst Pills, even if I encounter an enemy at the level of a sword master, I can easily kill them. Chu Feng was very satisfied, and after opening them, he installed them separately.

He decided to sell two and keep one for himself.

Opening the door of the alchemy room, Chu Feng strode out. By this time, the class was over.

"Chu Feng, how is it, has the refining been successful?" Liu Pingpi greeted him with a smile.

Obviously, this guy should be waiting for Chu Feng on purpose.

"Alas, Lady Luck can't take care of me every time!

"But I also have a lot of gains, and if I practice a few more times, I believe there will always be a time to succeed. ”

Chu Feng naturally couldn't tell the truth to Liu Ping.

Hearing Chu Feng's failure, Liu Ping showed a hint of a smile and said pretendly, "Chu Feng, you and I are small, and you can really perform amazingly in the alchemy class today." How about we go have a drink?"

"Don't go, my eldest brother controls me very strictly, and he will definitely scold me again when the time comes!" Chu Feng couldn't figure out what Liu Ping wanted to do, so he hurriedly refused.

"Go, go, go, your eldest brother, I will intercede for you, and I will guarantee that everything will be fine! Haven't you always wanted to know what happened to your Sword King's Mansion?"

"I'll just get some of them, and I'll tell you all about them when the time comes. ”

Liu Ping smiled enthusiastically, and he couldn't say anything, so he pulled Chu Feng and left.

It's just that in the depths of his eyes, there is clearly a chilling murderous intent. Chu Feng stole his limelight, which made his killing intent towards Chu Feng even stronger.
