As Lin Feng picked up the cold marrow branch, a bone-chilling chill quickly penetrated through his fingers.
This terrible chill almost made his entire arm numb.
Looking at the ice that quickly covered his arm, Lin Feng mobilized the emerald green flame in his body to expel the chill.
With a slight flick of his finger, the cold marrow branch was accurately thrown into the medicine cauldron.
Then the strange fire in it rolled and quickly rushed up to wrap it up.
However, facing the burning of the flames, the cold marrow branch did not sit and wait for death. Instead,
it continuously emitted icy mist, trying to use the low temperature of the ice to extinguish the flames that wanted to burn it.
The mist and the light green flame eroded each other, and with a hissing sound, the white mist that this thing continued to emit gradually filled the entire medicine cauldron.
Because the cold marrow branch needs to condense hundreds of years of extremely cold energy before it can be formed.
Therefore, relying on these energies, it actually stalemated with the Glazed Lotus Heart Fire for a while.
However, this cold marrow branch was isolated after all.
Unlike the Glazed Lotus Heart Fire, it was supported by Lin Feng's Dou Qi.
Therefore, after a period of time, it finally couldn't withstand the terrifying high temperature of the strange fire and was defeated.
The ice-like surface began to show signs of melting.
This refining lasted for several hours, and the cold marrow branch was completely defeated by the strange fire and turned into a ball of snow-white medicinal essence.
Feeling the extremely rich energy in the ball of medicine liquid.
Lin Feng breathed a sigh of relief, and with a wave of his hand, he stored it in the jade bottle.
After that, he didn't have time to stop, took a pill to restore Dou Qi, and picked up another jade box.
He took out the medicinal materials inside and threw them into the medicine cauldron, and continued to refine.
As Lin Feng continued to refine, the empty boxes on the ground gradually increased.
In the end, the ground was full of empty boxes that had been opened.
Beside Lin Feng, there were more than a dozen jade bottles filled with medicinal essence.
However, there was no sign of happiness on his face.
Because even the apprentice of the pharmacist knew one thing: the most difficult step in refining the elixir is always fusion!
Seeing that all the medicinal materials had been refined, Lin Feng immediately controlled the liquid medicine in the jade bottle beside him, allowing them to enter the medicine cauldron in an orderly manner.
After that, a huge soul power suddenly came out from the center of his eyebrows.
These energy liquids of different colors were pressed to the same point.
As expected, the rare medicinal materials in the medicine cauldron were completely scrapped.
Seeing this, Lin Feng exhaled lightly and had to continue to repeat the previous actions
. After the second, third, and fourth attempts all failed.
Finally, when he refined it for the fifth time, he got a Pozong Pill as he wished.
Putting it into the jade bottle, Lin Feng was happy, but also a little helpless.
Although the elixir was successfully refined, the price was really a bit high .
Thinking of the four sets of rare medicinal materials that were wasted before, the waste of heart could not stop bleeding.
After a while, he shook his head and said with a wry smile: "It seems that the level of alchemists is not so easy to improve. Even though I now have enough soul power and a large number of alchemy books, I still encounter so many problems when I want to upgrade my alchemy skills."
But thinking of the dried corpse of the Sky Demon Phoenix, he felt better.
"It's okay, as long as I can trade that thing, these costs are still worth it."
He comforted himself in his heart, then stood up, pushed open the heavy stone door, and walked outside.
He had been in seclusion for so long, he had to see how Medusa and the others were preparing for the auction.
"Old Yao, can you help me see what this thing is?"
After taking a look around Tianbao Pavilion and seeing that they were well prepared, Lin Feng went to the treasure hunting department and talked to Venerable Tianhuo who was looking for medicinal materials.
While talking, he took out the copper scroll that had been stored in the ring for a long time and obtained in the Warcraft Mountain Range.
"Hey, this thing, let me see it."
Seeing the copper scroll covered with copper rust, Yao Tianhuo was slightly surprised.
This ancient information storage method was already rare in his era.
According to the information he collected during this period, this information storage method has now been lost.
And now, it can still appear in Lin Feng's hands, which makes him extremely curious.
Seeing the former's surprised look, Lin Feng roughly knew that Venerable Tianhuo must have seen this kind of thing.
Without much hesitation, he threw it directly to Yao Tianhuo.
After taking the thing, Venerable Tianhuo immediately floated to the window.
With the help of the scorching sun above his head,
he could see the artificial marks on the copper scroll clearly. As he watched for a longer time, his head was almost touching the copper scroll.
After a while, he turned his head to look at Lin Feng and slowly said, "Where did you get this copper scroll?"
"Well, when I was a fighting master, I stole it in the lair of a sixth-level purple crystal winged lion king."
While speaking, Lin Feng suddenly recalled the time he spent with Yun Yun in the Magic Beast Mountain Range.
"Good guy, you are not only lucky, but also very brave. You dare to go deep into the lair of a sixth-level magic beast to steal things at the level of a fighting master."
Hearing the former's feat, Yao Tianhuo couldn't help but pull the corner of his mouth and said in surprise.
Hearing this, Lin Feng shook his head and said with a wry smile: "At that time, the Amethyst Winged Lion King was held up by other people, and there was only a third-level cub inside. Otherwise, I would have become their snack before I even got close to the monster's nest."
"But Master Yao, what on earth is this thing? I wanted to burn it with beast fire before. However, I was afraid of burning it, so I gave up this plan."
After listening to Lin Feng's description, Yao Tianhuo said unhappily: "Fortunately, you gave up this idea, otherwise the things inside would have been reduced to ashes."
"Then what on earth is this thing?"
Looking at Yao Tianhuo's mysterious look, Lin Feng couldn't help but asked directly.
"You are lucky to meet me. This copper scroll is a method used by people in ancient times to preserve information. Its essence is in the grooves with a few marks. Those powders that look like copper rust are actually materials used to store information."
While speaking, the Skyfire Venerable threw the thing back to Lin Feng and continued: "However, since this thing seems to have been buried in the soil for a long time, you need to peel off the powder and clean up the impurities before you can use it. But you have the strange fire, so you can just burn the impurities with fire."
