The middle-aged man of the shrewd demon clan looked at the token, and his eyes showed a fine light.

He glanced at it and said, "Gongzi Chen, I think you should have obtained this order from him, right?"

When Chen Shaofan heard this, his brows furrowed slightly: The other party is trying to get to the bottom of it!

Seeing Chen Shaofan frowning, the middle-aged man couldn't help but smile and said:

"Chen Gongzi, don't get me wrong, I just asked casually, there is no malice, like those of us who work in regular commercial houses, just to make money with integrity!

This token is a voucher to enter the Demon Wind Star Yin Yuan Crystal vein, which is auctioned by the Demon Wind City Lord's Mansion, and each piece is worth more than five million Yin Yuan Crystals. ”

"Yin Yuan Crystal Mine?" Chen Shaofan said curiously.

"It seems that Chen Gongzi has just arrived at the Demon Wind Star not long ago, if my guess is correct, you are an ascender!" said the middle-aged man of the shrewd demon clan with a smile.

Chen Shaofan did not deny it and nodded.

"Then I'll explain it to Chen Gongzi, and I hope that in the future, Chen Gongzi will come to the Demon Wind Trading House to find me!" said the shrewd middle-aged man.

"Okay, I will definitely bring you bigger business in the future!" Chen Shaofan said with a smile.

The shrewd middle-aged man nodded, he could see at a glance that the man in front of him was not simple, and it was really possible to bring him bigger business in the future, so that his status in the Demon Wind Trading House would be improved.

The commissioners in the Demon Wind Trading House all rely on performance to speak.

Whoever makes the most of the performance gets paid.

The shrewd middle-aged man, naturally unwilling to lose this potential big customer, said with a smile: "The Yin Yuan Crystal Ore in the Immortal-level Plane is different from the Spirit Crystal Ore veins in your original mortal-level plane.

The Yin Yuan Crystal vein is made up of the corpse of a powerful alien existence in ancient times, buried deep in the ground and evolved over endless years, and each Yin Yuan Crystal contains Yin Yuan power.

And the Yin Yuan Crystal has a special role, which can be used to arrange arrays, alchemy, and refine......

The Yin Yuan Crystal veins formed by the evolution of the corpses of powerful alien powerhouses will have mysterious and special prohibitions, some of which can only be mined by demons who do not exceed the four levels of the Demon Xuan Saint, and some can only be mined by women...... In short, there are all kinds of prohibitions.

The Yin Yuan Crystal Vein under the Demon Wind City of the Demon Wind Star is the only Yin Yuan Crystal Vein in the Demon Wind Star, and it will be opened once every three years and lasts for a month.

The Demon Wind Yin Yuan Crystal vein can only be entered by those who have cultivated no more than the Demon Xuan Saint Nine Fold, and there are many benefits to mining the Yin Yuan Crystal inside......

Because of such benefits, the 'Yin Yuan Order' that can enter the Yin Yuan Crystal Vein is very valuable, and it is difficult for ordinary people to get their hands on it.

Demon Wind City would take out 10,000 yuan to buy every year, and sometimes the price of one piece could reach tens of millions of Yin Yuan Crystals. ”

When Chen Shaofan heard this, his heart couldn't help but feel hot, and he also wanted to enter the Yin Yuan Crystal vein, so that his cultivation would make great progress.

He looked at the middle-aged man of the shrewd demon clan and continued to ask, "I don't know, when will the Yin Yuan Crystal vein be opened, will there be any danger in entering it?"

"Now there are still three months before the Demon Wind Yin Yuan Crystal Vein opens. As for the danger, there must be one, and it's still great.

If you enter it, not only will you have to face the attacks of the special creatures in the Yin Yuan Crystal Vein, but you will also have to be on guard against those ......demons who are not kind enough to enter the Yin Yuan Crystal Vein together," the shrewd demon middle-aged man said in detail.

After Chen Shaofan learned of these news, he hugged his fist at the shrewd middle-aged man and said: "Thank you for reminding me! If you answer these questions for me today, I won't let you suffer, and you will know in the future how much benefit I will bring you!"

After speaking, Chen Shaofan said goodbye and left.

He was going to find a place to live, and began to refine the Yin Demon Pill with peace of mind, striving to improve his cultivation, and preparing for the Yin Yuan Crystal to open and enter it in three and a half months.

Chen Shaofan came to the inner area of Demon Wind City, an area called Demon Yuan Ju.

The Demon Yuan Residence is a complex of buildings with large and small families, and these buildings are used for rent.

Depending on the amount of yin energy and the size of the floor area, different rents are charged.

Chen Shaofan spent five million Yin Yuan Crystals to rent a single room containing Yin Yuan Qi, where he could live for a year.

He entered the private room, which was a practice room with an area of about twenty zhang, and the walls around it were covered with demonic patterns, and a light shield shrouded the room.

This is a demon formation that can block the prying eyes of the outside world.

After Chen Shaofan came here, he immediately sat down cross-legged, and with a move of his mind, he entered the chaotic infinite space, and came to the twenty-four times the time flow stone.

He saw that Yang Yuan's true body was cultivating with his eyes closed, so he didn't bother.

The Yin Yuan True Body took out the first, second, third, and fourth grades of the Yin Demon Pill and comprehended it.

He now possessed the beast cores and beast blood of the first-order, second-order, third-order, and fourth-order Yin Beasts, and he could only refine the fourth-grade Yin Demon Pill at most.

Time passed imperceptibly, and a few days passed in the blink of an eye.

Yin Yuan's true body fully comprehended the first to fourth grade Yin Demon Dan Fang, and as soon as his mind moved, a white light flew out.

Guanghua turned into a cute doll with two braids to the sky is Huobao, and his round eyes full of spirituality stared at the master, and said, "Master, is there anything you call Huobao?"

"The master needs the fire treasure to help the master refine the Yin Demon Pill!" Chen Shaofan said with a smile.

"Okay!" Huobao obediently agreed.

Chen Shaofan handed over a storage demon realm to Huobao and said, "It contains the materials for refining the Yin Demon Pill, you can take it to refine the Demon Pill!

"Okay, it's not hard!" Huo Bao said in a childish voice.

The words fell, and he gestured towards his master's arm.

A ray of brilliance galloped out, turning into a mottled bronze ancient tripod, full of traces of time.

Huobao's mind moved.

Airplanes!

The heavy lid opened, and Huobao galloped into the ancient tripod with the storage ring.

Soon.

Bang!

Flames ignited on the surface of the ancient ding, and slowly rotated.

After taking a look at Yin Yuan's true body, he took out the only remaining bit of the three-grade Yin Demon Pill and began to refine and absorb its medicinal power to improve his cultivation.

Time goes back half a day.

From the bronze ancient ding, wisps of bloody faint fragrance escaped.

Airplanes!

Soon, the heavy lid of the bronze ancient tripod opened, and a white brilliance flew out from it, manifesting the fire treasure.

He handed a jade bottle to Yin Yuan's true body and said, "Master, this is a bottle of Yin Demon Pill, you take it and refine it first!"

Chen Shaofan took the Yin Demon Pill, smiled, and nodded.

The fire treasure continued to gallop into the bronze ancient tripod and continued to refine the Yin Demon Pill.

The sun rises and the moon sets, day and night reincarnate, and time passes slowly like the flowing water.

In the blink of an eye, five years had passed in the Chaos Infinite Space.

In the outside world, almost three months have passed, and the day of the opening of the Yin Yuan Crystal vein is approaching.
