Chapter 2708： The recipe of Burning Blood Pill!

Even if that person is dead, I don't know how many years, the things he left should still have this kind of breath.

And soon, Chen Feng stopped beside the biggest flame pit.

This flame pit, Chen Feng remembered that the strongest and largest among the bloodthirsty flame demons he had killed just now came from this flame pit.

Chen Feng came to the flame pit and looked down.

In the flame pit was just a huge red feather thunder tartar lying quietly, but nothing else.

Chen Feng stretched out his hand and sucked up the red feather thunder tartar.

Then, he walked around here twice, his brows raised slightly: "No, I obviously feel the breath of a human warrior here, why can't I find it?"

Chen Feng suddenly stretched his brows, and laughed: "Unexpectedly, this bloodthirsty flame demon would even play around."

With that, Chen Feng jumped directly into the flame pit without any hesitation.

Seeing this situation, Ji Caixuan exclaimed: "Master."

Chen Feng's voice came from the flame pit: "Don't worry, I'm fine."

The flame pit was not so deep, only more than a hundred meters long, and Chen Feng drifted down slowly.

It was still hot inside, but the flame disappeared, and it was not too dangerous for Chen Feng.

When Chen Feng came to the bottom of the flame pit, he found that it turned out that the flame pit had a small mouth and a big belly, and there was a full 100-meter radius below.

Chen Feng looked around and saw that the stone walls here were extremely smooth, burned to a blue color by the flames, a bit more condensed than the strongest metal.

But suddenly, Chen Feng frowned and stared at one of them.

He shook his figure, flashed directly, and came to a rock wall.

There were several small holes on this rock wall. This small hole seemed uncommon, but Chen Feng immediately discovered that it was wrong.

Because this small hole was definitely caught artificially, Chen Feng directly inserted his five fingers into it.

Then, he felt a slight looseness at the end of the room.

Chen Feng's heart was shocked, and he pressed his finger inward, then he pressed in.

Then, he turned his hand aside.

As he turned around, the rock wall beside him cracked directly, and a gap appeared for one person to enter.

Chen Feng looked inside and didn't feel the slightest danger, so he just stepped in.

He came into this gap.

The gap was very shallow, only three or four meters in length. When Chen Feng came to the end, a stone chamber appeared in front of him.

This stone chamber is not too big, the height is only two or three meters, the width and length are about the same number, and it can only accommodate a few people.

After Chen Feng came in, his eyes suddenly narrowed.

In the middle of this room, a skeleton was sitting cross-legged, and his palm was holding a black scroll.

This skeleton has existed here for many years, and an extremely old aura hits his face.

Chen Feng glanced away, and everything in this stone room fell into his eyes.

He raised his eyebrows and gave a soft hey.

It turned out that in this stone room, it was not that simple. A long metal rod was placed in front of the skeleton.

The metallic end is connected to a huge metal gear. At the end of the metallic gear, there are dozens of small metal gears. These gears constitute a rather complex device.

The equipment went deep into the stone wall, and looked at the direction of the equipment, which was the direction of the largest flame pit.

At this moment, Chen Feng seemed to have thought of something in his heart, so he walked to the position of the skeleton and looked forward.

Sure enough, he saw that there were two small holes in his direction, through which he could see the location of the flame pit.

Chen Feng gently shook the metal rod, and as he swayed slightly, suddenly, there was a soft sound, and all the instruments were all running.

Then the stone wall made a huge vibration, and it stopped with a light click.

Chen Feng's figure flashed, and when he entered the flame pit, he saw that a huge alchemy furnace was already spinning down in the center of the flame pit.

At this time, the alchemy furnace was selected at the center of the flame pit, where the flame was the strongest.

Chen Feng clapped his hands and said, "Sure enough, this is no different from what I thought."

There was a look of wonder in his eyes: "The predecessor who sat in the stone room and turned into a skeleton is definitely an inexperienced strong, powerful and clever in mind."

"He actually thought of using the purple fire here to refine the pill. The flames here are extremely overbearing, but if used well, it will have a very powerful help to refine the pill."

"I'm afraid that the profound fires I got before can't compare to this purple fire."

The profound fire that Chen Feng had obtained before was quite tyrannical, but it was still a bit worse than the current Zihuo. There was no way, after all, it was the profound fire he got at a low level!

"The Purple Fire Swamp is so dangerous, everyone can't avoid it and can't wait to stay far away."

"And this senior, who is ingenious, actually uses the flames here to refine alchemy, it is really amazing."

"It's just a pity, somehow, died here."

Chen Feng also has no way of knowing who this senior is and where he comes from!

Chen Feng glanced at the alchemy furnace and shook his head. It was a pity that the alchemy furnace was decayed and could not be used.

He returned to the stone chamber and pulled the metal rod back.

Suddenly, the alchemy furnace shrank back again.

As soon as Chen Feng stretched out his hand, he picked up the black scripture in his hand. After opening the black scripture, there were seven big characters in it: the formula of Burning Blood and Naturalization Pill!

There was a burst of ecstasy in Chen Feng's heart.

"The formula of Burning Blood Pill, I got the formula of Burning Blood Pill?"

The formula of Burning Blood Creation Pill is what Chen Feng dreams of. Chen Feng needs an extremely large amount of Burning Blood Creation Pill to upgrade his level.

He is short on time, and his absorption speed is more than a hundred times that of others, so his demand for this is hundreds of times higher than that of warriors of the same level, which is extremely huge.

Just buying it can't even satisfy him, Chen Feng needs to refine it himself.

However, his current pharmacist level cannot be reached, because he was originally an 8-rank pharmacist, and to refine the Burning Blood Pill, at least a golden robe pharmacist of the first rank is required.

And he has no prescription.

Chen Feng once asked Lu Yutang about something about the prescription. Lu Yutang didn't hide anything from him. He directly frankly said that the price of the formula is very different because of the different levels of Burning Blood Pill.

Like the first-level formula of Burning Blood Pill, you can buy more than a thousand dragon blood amethysts.
