Chapter 644 The Whereabouts of the Ten Thousand Year Black Wood

Cao Xu glanced at him and laughed, "The auction will be held in an abandoned mining area."

“Has such a joint auction ever been held before?”

"The passages to the eighteen underground mining areas were only opened in the last hundred years. In the past, trade was only conducted through secret passages. This is the first time that a joint auction like this has taken place."

"For the first time..."

Henry Zhang was a little worried at this time. This kind of joint auction would be too dangerous.

On the one hand, the eighteen mines are full of ruthless people who were raised in the underground mines. They have no moral bottom line. If there is a case of black-eating-black, it will not be good.

On the other hand, with so many mines gathered together, it would be even more dangerous if the Holy Land got wind of the news and wiped out all of them.

After all, there are eighteen mines, and each of them has a Nascent Soul cultivator guarding it, which is not fun.

Thinking of this, Henry Zhang said, "I'd better not go."

"Brother Zhang, the items on auction this time are all the treasures of the mines."

"I am only a mid-stage Jindan cultivator, so I won't get involved in the auction of you big shots."

Cao Xu had a strange look on his face, and thought to himself, "You are not an ordinary mid-stage Jindan cultivator."

"Brother Zhang, this joint auction will have fifth- and even sixth-tier spiritual materials."

"That requires a lifespan."

"Many of them are ancient and rare items, including Cold Gold Divine Sand, Fire Essence Black Gold, Ten Thousand Year Black Iron, Langya Gold Jade, Ten Thousand Year Black Wood..."

"What? You mean the ten thousand year old black wood?" Zhang Xuan felt like a cat whose tail was stepped on.

To refine the Zixu Star Extreme Pill, you need to use ten thousand-year-old black wood as the main medicine, supplemented by the ancient elixir cloud root grass, third-level elixir purple spirit leaf, dragon tongue mushroom, and red flame root.

Among them, he has already obtained the ancient spiritual medicine Yungen Grass, as well as the third-level spiritual medicines Purple Spirit Leaf, Dragon Tongue Ganoderma, and Red Flame Root.

Now all that's missing is the thousand-year-old black wood.

He had previously asked Hanekawa about the whereabouts of the ten thousand year old black wood, and was told that it might be in the Chaoxi Sea.

There are too many uncertainties in the Chaoxi Sea area.

I didn't expect to find this item in the underground auction market.

Zhang Xuan naturally would not go far away.

Once the Zixu Xingji Pill is refined, it will allow cultivators to use the power of the star Zixu to comprehend the supreme principles of the Tao.

For Zhang Xuan, it is a rare elixir that he must obtain.

This ten thousand year old black wood became something he must obtain.

Cao Xu saw the other party's anxious look and realized that the other party was extremely concerned about this ten thousand year old black wood. He nodded and said:

"Each mining area has compiled a catalog of the spiritual materials to be auctioned. There is indeed a thousand-year-old black wood in it, which seems to be contaminated by the five elements of evil spirits. However, it is an extremely rare spiritual material from the ancient times after all. If Brother Zhang wants to bid for this item, I'm afraid he will have to prepare more God Wing Blood Ore."

"This auction is indeed quite interesting. I will go back and discuss it with my Taoist partner and then give Brother Cao a reply."

"no problem."

Henry Zhang returned to the safe house.

I saw that Bu Yueling had completed her training.

"My husband has sold all the pills?"

"Yes."

After saying that, Henry Zhang took out the Divine Wing Blood Mine that he was selling the elixir for this time.

Of course, what was taken out did not include the two-thirds that he had stolen.

Bu Yueling glanced at her husband, and her intelligent eyes told her that he seemed to be worried about something.

"What do you want to discuss with me, my husband?"

"There is indeed one thing..."

As expected, she is my Taoist partner. I can't hide anything from her.

"We are a couple, there is nothing wrong with talking about it."

Zhang Xuan nodded and told about the joint auction held by 18 mining areas.

After hearing this, Bu Yueling said, "It's too dangerous. My husband should not go."

"But the thousand-year-old black wood is what I must obtain for alchemy."

"Is alchemy more important than life?"

"If it was any other elixir, it would be fine, but this is the Purple Void Star Extreme Pill. Once it is refined, it will allow cultivators to use the power of the Purple Void Star to comprehend the laws of heaven and earth."

"Can't cultivators comprehend the laws of heaven and earth only when they reach the Nascent Soul stage? Can elixirs also help in comprehending the laws of heaven and earth?" Bu Yueling was surprised.

"Other elixirs may not work, but this Zixu Xingji Pill definitely will." Zhang Xuan said firmly.

Looking at her husband's determined eyes, Bu Yueling knew that no matter how much she tried to persuade him, it would be useless.

"I know I can't persuade you, so I'll go with you."

"No, it's too dangerous, you stay." Zhang Xuan refused directly.

Bu Yueling glanced at Zhang Xuan again, tears welling up in her eyes.

"Ugh……"

Henry Zhang sighed and wiped away the tears from Bu Yueling's face.

Bu Yueling knocked Zhang Xuan's hand away, rushed into the house, and ignored him.

"Ugh……"

Henry Zhang sighed again.

"Since you have decided to go, you must be fully prepared."

Especially if you want to take a picture of this kind of thousand-year-old black wood, it will probably cost a lot of Divine Wing Blood Mine.

If we use barter at the auction, I'm afraid we won't be able to buy the Divine Wing Blood Mine even if we have it.

There is still half a month before the auction starts.

During the past half month, Zhang Xuan did not go mining, but concentrated on refining pills and accumulating as many supplies as possible in preparation for bidding for the ten thousand year old black wood.

There are plenty of mature second-level elixirs in his meditation space.

Furnace after furnace of second-level pills were refined.

He packed piles of Heavenly Ape Golden Pill, Heavenly Longevity Pill, Heavenly Sand Pill, Five Elements Small Miracle Pill, Zuowang Pill, Nine Fragrance Glazed Pill, etc. into his storage bag.

Just three days before the auction, after absorbing a large amount of the Divine Wing Blood Mine spiritual object, one of the Qingling fruit trees finally matured and bore fruit.

Zhang Xuan counted and found that there were 10 Qingling Fruits in total, enough for him to refine 10 furnaces of Qingsha Pills.

"Hahaha... this Qingling Fruit comes at the perfect time."

Zhang Xuan took out the recipe for refining the Qingsha Pill.

The main ingredient in refining Qingsha Pill, Qingling Fruit, is extremely rare, but other auxiliary ingredients are common.

Inject spiritual spring water into the cauldron inside the Dantian.

Zhang Xuan began to refine the first batch of Qingsha Pills with great caution.

The temperature, alchemy skills, and comprehension, all of these are no problem.

Everything proceeds in an orderly manner.

"Turn on the furnace!"

The first batch of Qingsha Pills was successfully refined.

A total of 20 pills were produced.

Touching the still warm Qingsha Pill in his hand, Zhang Xuan sighed: "I finally got this pill!"

Next, Zhang Xuan did not stop and continued to refine the Qingsha Pill.

He refined 10 furnaces in a row without any failure.

A total of 200 pills were produced.

"The Twelve Heavenly Sounds Diagram really didn't deceive me. It can really refine a third-level inferior elixir with 100% certainty."

Henry Zhang was ecstatic.

The reason why Qingsha Pill is scarce is not only because the main ingredient Qingling Fruit is hard to find, but more importantly, it is extremely difficult to refine.

Even a third-rank top-grade alchemist might not be able to successfully refine it, let alone produce 20 pills each time.

What made Zhang Xuan quite regretful was that he failed to refine the Qingsha Golden Pill.

However, he has no regrets.

After all, the Qingsha Pill is too precious and cannot be lost.

Heading to the auction soon.

The door of Bu Yueling's house was still closed.

"Yueling, please open the door. Your husband will be leaving soon."

The door still didn't open.

There was no response from inside.
