"How long can the aura seal of the Rongkun Treasure Furnace last?" Du Fan asked the white-clothed glutton.

"Don't worry, I know what to do. The white-clothed gluttony said absent-mindedly.

Du Fan sighed, and said a little helplessly: "I'll go out and come back in about ten days, and you'd better not cause any trouble for me during this period." ”

With that, he turned and walked away.

......

In a ruined ghost town, Du Fan, who is incarnated as a black-robed ghost clan, strolls through the slightly depressed streets, and eventually, he stops in front of a shop that buys and sells spiritual herbs.

The scale of the shop is not large, the boss is a high-grade ghost pawn, comparable to the foundation building period of the human race, and the guy who does chores in the shop is a human race in the qi refining period.

Du Fan suppressed his cultivation to the rank of a high-grade ghost soldier, and exuded a little coercion, which instantly shocked the shopkeeper and the Qi Refining Terran.

"I don't know that the seniors are coming, and the younger generations can't meet them in time, forgive the sins. The shopkeeper and the Terran men immediately put down what they were doing, hurried over, and gave a deep salute with a look of trepidation.

Du Fan flipped his palm, revealing a jade box, and inside was a small pile of black pill residues.

"Can you identify the origin of this elixir?" Du Fan didn't mean to talk nonsense, glanced at the other party, and asked directly.

"It's been ruined like this, I'm afraid it's a little troublesome to identify......"

Seeing that Du Fan frowned, the shopkeeper's heart jumped suddenly, and he hurriedly changed his words: "Seniors wait a minute, let the juniors prepare." ”

The shopkeeper slapped his waist pocket, and immediately a green glow flashed, revealing something the size of a crystal ball.

He endured the pain in his flesh, and chanted a spell at the green crystal ball, casting spells continuously, during which a small pile of pill residues floated out of the jade box and slowly injected into the crystal ball.

A moment later, there was a blur inside the crystal ball, and something that resembled a human face came out, but it was fleeting, and then there was a loud explosion, and the crystal ball shattered.

"What, it's a real ghost pill!" The shopkeeper's pupils shrank, and he couldn't help but exclaim.

"Yu Lan is a real ghost pill ......" Du Fan said to himself, he had never heard of this elixir, and he had never seen it.

The shopkeeper seemed to realize something, his expression was full of fear, and his whole body trembled.

Seeing this, Du Fan's face sank, and the sealing seal was immediately cast, and the shopkeeper and the Terran monk were instantly petrified, standing motionless.

Du Fan changed the law in his hand, emitted two wisps of divine thoughts, and launched a soul-searching technique on one person and one ghost at the same time.

Due to the low cultivation of the other party, it only took a few breaths to successfully search for the soul and erase some of the other party's memories.

"Yulan True Ghost Pill, Ghost Dao Refining Pill, Exclusive to the Ghost King, the quantity is very limited, it is impossible to buy and sell it, under the Ghost King, only the ghost marquis who has made immortal achievements can be rewarded, and there is only one chance in a lifetime, it is rumored that only after taking this pill can he have the qualification to achieve the body of a true ghost in the future, and its price is immeasurable......"

After learning this information, Du Fan was in a daze, and he didn't know whether he was lucky or unlucky, there were more and more things that could not be seen on his body, if the matter got out, it would definitely be a catastrophe for him, just like a three-year-old child holding a large piece of gold ingots dangling in the market, and the number of such things as the Yulan True Ghost Pill is limited, almost each one represents a ghost giant, three ghost marquis fell in a row that day, and the water of the Yellow Spring was also exposed, and all kinds of things can be easily linked together during the period.

"Forget it, if there are more lice, it doesn't itch, the most important thing at the moment is to find that material. ”

Du Fan hurriedly left the store and went straight to the largest pharmacy here.

This time, he quietly infiltrated a secret room and directly searched for the soul of a ghost alchemist.

Fortunately, this ghost clan alchemist happened to know the main materials and origin required for the refining of the Yulan True Ghost Pill, and after some inference, Du Fan basically determined that most of the breath of the origin of the earth came from the spirit plant called "Seven and a Half Days".

This is a very special plant, like a flower is not a flower, like a grass is not a grass, the required growth environment is not directly related to the origin of the soil, Du Fan got the "seven and a half months" in the residue of the pill, it should be just a coincidence, its origin happens to exist in the origin of the soil, which is contaminated with a little breath, if you change a real ghost pill, it may not have anything to do with the origin of the soil.

"July and a half" is a rare species, can not be cultivated artificially, can only grow naturally, there are only a few well-known production areas, and they are all classified as "private gardens" in the Yin Si Palace.

But fortunately, it may be because of the Yin Si Palace's one-handed cover of the sky, no one has dared to fight the idea of the Yin Si Palace, so those production areas are only symbolically circled, and in fact, there is no high-level protection, just some simple prohibitions, a quasi-heavenly soldier, with a team of high-grade ghost soldiers, the overall lineup is far inferior to the Feisheng platform, with Du Fan's ability, it is simply free to come and go.

The nearest "July and a half" production area is less than a million miles away, and Du Fan acted immediately and arrived on the same day.

......

A month later, Du Fan returned to the temporary cave house.

As soon as he entered, he saw a black shadow flashing, and the speed was extremely fast, and even he couldn't react, only to feel that his shoulder suddenly sank, and a small thing was lying on it.

Du Fan was instantly shocked into a cold sweat, and when he looked at it again, he was even more dead, and it was nothing else lying on his shoulder, it was the small hairball of the 10,000-legged borer clan.

"Don't be nervous, this little thing has been subdued by me, and it will be my war pet in the future, no, it's a mount, haha......" The white-clothed gluttony walked out of the secret room, with a villain's proud face, laughing non-stop, and his mouth was almost grinning to his ears.

At this moment, the little furball's figure flashed, shook off Du Fan, and instantly appeared in the white-clothed glutton's hand, rolling back and forth, very intimate and cheerful.

Seeing this scene, Du Fan breathed a sigh of relief.

"The matter of the Rongkun Treasure Furnace can be dealt with now. Du Fan said.

"No problem, let's go, I'll point you out. "The gluttonous white clothes are in a good mood, and it is rare to be so refreshing.

......

I don't know how many thousands of miles away, in a magnificent hall with a gloomy atmosphere, there was a roar and vibration, and black gas was permeated, all of which originated from a huge copper furnace, and its form and style were the same as the Rongkun Treasure Furnace that Du Fan obtained.

The next moment, the huge copper furnace suddenly fell silent, no longer shaking, and no longer spewing thin black gas.

"The magic weapon mark has been completely erased, I am really curious, who is so bold. ”

A tall middle-aged man stood in front of the copper furnace, his face sinking like water, and his eyes were cold and terrifying.

"Everyone in the world knows that I Sanghuai has the Xuantian-shaped treasure Rongkun treasure furnace, but I don't know that the Rongkun treasure furnace is divided into two furnaces, and I don't know that the second furnace of the mother and the mother add one more thing, it is a real Xuantian spiritual treasure, although the mark of the sub-furnace has been erased, but the mother furnace is in hand, I'm afraid I can't find you, but now there are more important things to do, so let you live for a while." ”
