"Childe, this is the warehouse of my Tianfang Pavilion, you can choose at will, I will wait for you here!"

The old man said to Chu Yan very politely.

Chu Yan nodded and stepped inside.

Entering the warehouse, looking around, there were hundreds of wooden shelves, there were medicine pods of various sizes and shapes, and on the ground in the corners of the walls, they were also piled up everywhere, which made Chu Yan a little stunned.

"It seems that this Tianfang Pavilion is really making money!"

Chu Yan muttered to himself, walking cautiously along the empty ground, his eyes scanning around, checking the various medicine pots.

"Although it's just an ordinary medicine tripod, let's choose a good one carefully!"

Chu Yan thought secretly, but he walked farther and farther, and inadvertently, he actually penetrated into a room that was only a few hundred square meters in the middle.

It's much smaller than the thousands of square meters outside, and it gives me a feeling of crowding, especially with the countless dusty pods of all kinds.

Chu Yan carefully selected, and basically swept it away.

"Huh!?"

Suddenly, in Chu Yan's sea of consciousness, the yellow martial soul light cluster suddenly woke up and flew in Chu Yan's sea of consciousness.

Chu Yan's body was stunned and stopped.

This feeling is just like when the Flame Martial Spirit met the three-star demon fire.

"Could it be..."

Chu Tian groaned slightly, but his eyes flashed.

Raising his hand and touching a white medicine tripod beside him, this is a hexagonal medicine tripod, double circles up and down, surrounded by six sides of equal length, it looks extremely peculiar in shape.

Slowly stretched out his hand, and when Chu Yan was about to touch it, the yellow martial soul light group in the sea suddenly stopped.

"No, not it!?"

Chu Yan was stunned for a moment, then stretched out his hand to push it away, and behind it, a gray rectangular medicine tripod appeared.

"Rectangle!?"

Chu Yan was stunned for a while.

The shape of the pod is mostly round, with a small number of squares and polygons, and this kind of rectangular shape is extremely rare.

This medicine tripod is so strange, no matter how you look at it, it feels like a coffin, and there are vague lines on the six faces.

Holding it in his hand, the yellow martial soul in the sea of consciousness immediately went berserk, rushing around, wanting to get out of his body.

"That's it!"

Chu Yan forcibly suppressed the light cluster of the yellow martial spirit, and walked out with this medicine statue that was nearly one meter long.

Experience!

When the martial soul riots, it is very likely to encounter rare things.

Moving this medicine tripod to the door, the old man was suddenly stunned when he saw it.

"Childe, why did you choose this medicine tripod, this medicine tripod has been placed here for I don't know how many years, because the appearance is like... Coffin, so, no one has ever taken a fancy to it, Childe, are you sure you chose it? ”

The old man stroked his beard and persuaded kindly.

"That's it!" The more Chu Yan looked at it, the more he felt good, and said resolutely.

The old man persuaded two more words, and saw that Chu Yan's attitude was firm, but he didn't say anything anymore and sent Chu Tiangong to the door of the store.

After putting the coffin medicine tripod into the contract space, Chu Yan left Fang Tiange, and found a common Qi Refining Pill in the bazaar, purchased more than a dozen elixirs needed to refine Qi Refining Pill, and left the black market.

Back at the Grand Commander's Mansion, Chu Tian entered the room and closed the room.

Summon a few things and place them neatly in front of you.

Luo Tong Dan furnace, Qi refining pill pill, a small pile of elixir, all ready.

Pick up the herbs you bought, put them in your hands and observe them carefully, looking at each one very carefully.

Although he is not a pharmacist, he has watched his father run the elixir business since he was a child, and after a long time, he gradually has some experience in elixir.

"There are many plants, trees, and spiritual plants in heaven and earth, and some can be taken directly, but if you refine the face pill, the effect will be doubled."

Chu Yan pondered and checked all the elixirs once, but frowned slightly.

"It's still unstable, the focus of alchemy is the probability of becoming a pill, although it is the simplest yellow-level two-star elixir, it is still very easy to fail."

After sitting down cross-legged, Chu Yan took a deep breath, his gaze fell on the Luo Tong Dan furnace, and under the urging of the true qi, the flame martial soul rose, and a fiery red Dan flame appeared in the palm of his hand.

This pale yellow three-star demon fire, after being refined by the flame martial spirit, the color changed to fiery red, although I don't know how many star levels it is, but it is definitely higher than the original three-star.

And with the last time the Flame Martial Spirit devoured the corpse of the man in black, the color of this Dan Fire seemed to have changed somewhat.

With a wave of his hand, he threw the Dan fire into the Dan furnace, and the flames burned violently in the Dan furnace at the whole time, and the content of the whole room rose hot, and the Dan furnace was even more visible to the naked eye.

"Qi Refining Pill, an ordinary second-grade pill, suitable for below the Innate Realm." Chu Yan was extremely serious, and after thinking about the prescription of the Qi Refining Pill several times in his mind.

Start alchemy...!

Picking up an elixir, the true qi in the body was emitted, forming a strong qi and rubbing it fiercely, and suddenly the elixir turned into countless powders and fell into the Dan furnace.

With a bang, puffs of smoke immediately rose from the Dan furnace.

Chu Yan's face tightened, and the moment the mist appeared, his hands flew and rolled all the prepared elixirs into powder and sprinkled them into the Dan furnace one by one.

Leaned out his divine sense and carefully controlled the temperature of the Dan Fire in the furnace, making the medicine mist thicker and thicker.

Chu Yan's brows were furrowed, his divine sense was controlled to the limit, his eyes flashed with bright light, staring at the Dan furnace, controlling the flame to slowly change the temperature.

The sweat on the forehead rolled down in large quantities under the high concentration of mental concentration.

Rumble!

An hour later, a muffled sound erupted from the hearth.

At the same time, the scorched black mist dispersed, and Chu Yan only felt a strong pungent smell coming, and under coughing again and again, he hurriedly looked into the furnace.

A pile of black residue!

"Failed..."Chu Yan frowned, his eyes were thoughtful, and he recalled all the details of the alchemy just now.

There was no disappointment, no discouragement, but a full immersion in reflection.

For a whole night, Chu Yan's mind reflected on the process of the first alchemy thousands of times.

Temperature, timing, proportion, etc., these conditions are related to the probability of becoming a pill, and if the difference is a millimeter, there will be a difference between heaven and earth.

The next day, at dawn, Chu Yan started the second furnace.

Rumble!

The Dan furnace burst again, and the large cloud of smoke dispersed, and the furnace was still a mass of debris.

Chu Yan's eyes tightened, the persistence in his temperament rose up in his heart, he reached out to pick up the residue, carefully examined it, and repeatedly compared the Dan Fang, Chu Yan completely fell into a madness.

Another day has passed....

When the furnace was opened for the third time, watching the elixir powder in the furnace slowly fuse into a ball, a look of hope had just risen in Chu Yan's eyes.

Rumble!

The failed Dan furnace made a roaring sound, and Chu Yan's eyes were round, staring at the Luo Tong Dan furnace deadly.

After a long time, Chu Yan sat down gently, closed his eyes, fell into the sea of knowledge again, and pondered carefully.

Sunrise and sunset, the moon and sunshine, day and night pass....
