With a stomach full of doubts, Ling Feng quickly approached the surroundings of the Dan furnace.

Feeling the terrifying aura of flames around Ling Feng, the spiders lying on the ground around him immediately retreated into the gloomy corners, not daring to act rashly.

Ling Feng looked up, and there seemed to be a vent above, shining a ray of light down and aiming directly above this Dan furnace.

Then, Ling Feng squatted down again, studied the magic circle below, and finally came to his senses.

It turned out that this Dan furnace actually used the magic circle as a medium to communicate with heaven and earth, absorb the essence of the sun and moon in class, and communicate with the earth's leylines in the next class, and constantly urged the magic circle with the aura of the two, condensing a very weak "ethereal fire" to carry out alchemy.

Before this, Ling Feng had only recorded some descriptions of the "Ethereal Fire" in some ancient records, but he couldn't imagine that he had actually seen it with his own eyes now.

"With ethereal fire, sacrifice for tens of thousands of years......"

Ling Feng held his chin and muttered in a low voice: "What kind of elixir is it that is worthy of the Great Sect Master of the Ancient Sect, who has taken such painstaking efforts to build such a dark room under the Tiandan Pavilion. ”

Obviously, this place was originally thought to be built, and after devouring a large amount of spiritual pills, the medicine spider initially opened up its spiritual intelligence, and in its long life, it wandered around the Tiandan Pavilion indiscriminately, and found this place by mistake.

It is also because of its initial spiritual wisdom, so it probably knows that this is also a very important elixir, so it has been guarding this place, just waiting for the elixir to be completely formed.

Unfortunately, it didn't wait for that moment after all.

"What, did you find anything?"

Li Bufan held his sword, walked over slowly, and asked lightly.

"I did find something. ”

Ling Feng nodded slightly, "This is an ancient alchemy array, using ethereal fire to absorb the sun essence and moon bloom of heaven and earth and the spiritual energy of the earth's veins, and sacrifice the Divine Pill of the Vast World. ”

Although Li Bufan doesn't know much about Dan Dao, as long as he knows that the pill in this Dan furnace has been refined for tens of thousands of years, he knows that it is definitely a treasure among treasures, and it is a treasure of the world!

Yue Yunlan and the others also stepped forward and wandered around the Dan Furnace a few times with interest, but they naturally couldn't see any fame, so they could only ask Ling Feng: "Then how long does the spirit pill in this Dan Furnace need to be refined?"

"I don't know. ”

Ling Feng shook his head, "Originally, the ethereal fire was used to sacrifice alchemy pills, and in the records I know, the longest is sixty years. And this furnace of elixir, I'm afraid that because it hasn't had time to be refined, it has to fight a decisive battle with the extraterritorial heavenly demons, so it can't be opened for a long time. ”

"And later, this ancient sect turned into ruins, and naturally no one could take care of this furnace of elixir. ”

Ling Feng held his chin and analyzed, "If there is the assistance of an alchemist, it shouldn't take too long before the furnace can be opened." ”

After hesitating for a moment, Ling Feng finally decided to take action in person to speed up the process of alchemy.

Otherwise, it is completely dependent on the essence of the sun and the moon, but I am afraid that in a few hundred years, they may not be able to open the furnace, and they can only stay in the battlefield of gods and demons for ten days.

Although he is not absolutely sure, he can also take a risk.

Refining is wasted, that is, from nothing to nothing, and nothing is lost.

If it is practiced, it will be a furnace of ancient god pills!

"Xiao Fan, you stay by the side for me to prevent anyone from disturbing me, I will personally take charge of the furnace and refine this furnace of the Ancient Divine Pill!"

Ling Feng took a deep breath and said slowly.

"Big brother, I'm sure you can do it!"

Jiang Xiaofan grinned, immediately carried the big sword, walked to the entrance of the cave, and said in a deep voice: "Whoever wants to come in through the entrance of the cave must first step on my corpse!"

"Then I'll guard the left side to prevent those spiders from harassing me. Yue Yunlan also pursed her lips and said.

"I'm on the right......" Mu Qianxue hugged the little black cat and walked to the right side of Ling Feng to guard it.

......

After a while, everyone protected Ling Feng in the center, and Ling Feng also began to start from the ancient magic circle, trying to control the ethereal fire little by little.

Although Ling Feng has countless alchemies, it is also the first time he has come into contact with the ethereal fire, not to mention, this time he has refined a furnace of semi-finished products, if there is a slight mistake, these tens of thousands of years of spiritual essence will all be destroyed in one fell swoop!

Gently wiping away the fine sweat from his palms, Ling Feng breathed repeatedly to calm his inner mood swings.

Refining the Ancient Divine Pill, I was afraid that if I changed to any alchemist, I would only be more nervous and uneasy than Ling Feng.

Even if it is Hong Haotian, the president of the Alchemist Guild, or Yun Danqing, Su Dongling and the like, although they are dozens of years older than Ling Feng, in this case, they may not be as calm as Ling Feng.

Even, they probably don't have the courage to dare to control this Ancient Spirit Array.

"Heavenly Dao Divine Pattern, Condensation!"

Ling Feng clenched his fists, although the ancient magic array was different from the martial arts, but when the Heavenly Dao Divine Pattern was condensed, his comprehension and thinking ability would be doubled, which would be of great benefit to comprehending the ancient magic array.

A quarter of an hour!

Two quarters of an hour!

......

Ling Feng sat cross-legged in place, motionless.

An hour!

Two hours!

......

Ling Feng seemed to be petrified, and those companions around him could only wait silently, in terms of alchemy, no one among them could help Ling Feng with anything.

Finally, I don't know how long it has been, Ling Feng suddenly opened his eyes, and a faint flame floated in his hand, directly into the six-pointed star array.

"Whew!"

The flames rose, and the golden flames almost set the entire Dan furnace on fire, and the flames flickered, illuminating everyone's shadows like ghosts, constantly elongating and distorting.

In the originally dark cave, such a fierce light suddenly erupted, and those spiders hiding in the shadows suddenly retreated again and again.

These creatures that live in the shadows have a deep fear of light and heat.

"This ......"

Li Bufan's eyelids jumped wildly, although he was not very interested in Dan Dao, but in order to cope with the promotion assessment every semester, he still knew something about it.

The previous "ethereal fire" was extremely weak and extremely weak, and Ling Feng instantly urged such a domineering flame, can the materials in the Dan furnace withstand such a temperature difference?

Tuoba Yan and Mu Qianxue also frowned, this is already a common-sense mistake, it stands to reason that Ling Feng has the courage to refine the Ancient Divine Pill, he shouldn't make such a mistake.

Only Yue Yunlan and Jiang Xiaofan have always unswervingly believed in Ling Feng.

After all, Yue Yunlan had seen Ling Feng's alchemy ability, which could be called a miraculous skill, and he was able to use such an unreasonable method to create miracles.

And Jiang Xiaofan, this guy doesn't know anything about alchemy at all, he is almost brainless and blindly worships Ling Feng.
