In the end, Zhou Qing sent the five souls of the Huang family warriors into the underworld and then liberated them.

This was the only use these souls had for in his hands. Now they were being put to good use, giving off their final light and heat. Zhou Qing was very pleased.

As for the actual gains from this Yellow Springs experiment, Zhou Qing obtained five drops of liquid with unknown effects brought out from the Yellow Springs.

In later attempts, he tried to let the Yellow Springs Dragon enter the Yellow Springs alone, without bringing the soul along.

But unfortunately, if this happens, when the Yellow Springs Dragon returns, a layer of yellowish frost will not condense on its body surface.

It is obvious that the formation of that layer of yellowish frost is related to the souls entering the underworld.

Zhou Qing suspected that it should be the materialization of some kind of power that eroded those souls.

The human soul follows the Yellow Spring Dragon into the Yellow Spring, causing a reaction there and beginning to corrode it.

The existence of the Yellow Springs Dragon itself resisted most of the erosion and isolated them outside its body. When it left, it brought this power out with it.

The Yellow Springs Dragon itself is a Yellow Springs creature, and it will definitely not be corroded if it enters the Yellow Springs alone.

This is the same reason why Zhou Qing’s soul was rejected by the human world after it transformed into the Yellow Springs Dragon.

Creatures from the underworld should not appear in the human world, and vice versa.

It’s not that he didn’t want to make use of those five souls and let the Yellow Springs Dragon go to the Yellow Springs a few more times to get some Yellow Springs liquid back.

The problem is that their souls are corroded beyond recognition after entering the underworld once, and they cannot withstand the second time.

Zhou Qing collected the Yellow Springs Dragon. Although the harvest this time was not as big as he had initially imagined, it was still not nothing.

"I can't directly enter the underworld now. Maybe I can try it after I cultivate to the realm of manifestation of sainthood."

Zhou Qing had already made up his mind and decided to wait until his soul cultivation level improved a little before trying again.

The realm of holiness is not far from him.

However, with his foundation and strength, once he is promoted to the Manifestation of Sainthood, his combat power will definitely not be weak in the Manifestation of Sainthood field.

Although it has not yet reached the level of Yin God, its ability to resist risks is much greater than it is now.

Yin Shen is a huge qualitative change. From this step on, even if one is a peerless genius, the ability to fight against opponents of higher levels will gradually weaken.

Under the Yin God, the peerless genius can even fight across a major realm, but when it comes to the Yin God realm, that is no longer possible.

Those who can cultivate to this level are definitely not weak. Their foundation and other aspects may be worse than yours, but they definitely cannot be too much worse.

The weak are not qualified and cannot reach this level.

In the Yin Shen Zhen Xue realm, being able to kill an enemy across a small realm is a very remarkable thing.

The further you go, the more difficult it becomes to jump levels.

Zhou Qing estimated that if he wanted to fight with Venerable Yin Shen, then after breaking through to the Manifestation of Sainthood, he would need to continue advancing for a while in this realm.

"And this thing..."

Zhou Qing took out five jade bottles, each containing five drops of Yellow Spring Liquid.

He really had no idea what this thing was used for, but Zhou Qing felt that it was impossible for it to have no effect at all.

After all, it was something brought out from the underworld.

Zhou Qing shook his head. "It's a pity that Aunt Mo is not here. She is also beyond Snail's contact range. Otherwise, I could ask her."

Among the people who were close to him, there were only two who might have recognized such a thing.

Thinking of this, Zhou Qing put away the five jade bottles, preparing to find out its details in the future.

It just so happens that I have to open a treasure chest later, so it's just on the way.

The next day, Zhou Qing said goodbye to Bai Tian and the others and left Heiyun Town directly.

After a while, Yunlong City came into sight.

After Lu Qingmo left, the only person left who might know what that liquid was was naturally Ao Xuanwei.

If this thing is indeed precious and useful, then Zhou Qing would find a way to get more and stockpile it no matter what.

On the small island in the middle of the lake, Ao Xuanwei was already waiting for Zhou Qing.

Before coming, he contacted Ao Xuanwei in advance and made sure that she was in Yunlong City before coming here.

When Ao Xuanwei saw Zhou Qing for the first time, she smiled and said:

"It's really rare. You've come to my place three times this month."

Zhou Qing was a little embarrassed. He knew in his heart that he was the typical person who would not visit someone for no reason.

"I plan to visit various counties in Tianyue County later. I just happened to get something recently, but I can't recognize it."

"It happened to be on my way after leaving Black Cloud Town, so I wanted to ask you to help me take a look."

Ao Xuanwei looked at Zhou Qing with a puzzled look in her eyes.

"Another treasure I can't recognize?"

"I'm afraid you have looted all the treasures hidden in Tianyue County."

How can it be easier for you to find treasures than for a dragon like me? This doesn’t make sense!

"It was just a lucky break."

"Look at your treasure."

Zhou Qing took out a jade bottle and handed it over.

"Yellow Spring Liquid? How could you get this thing in Tianyue County?"

Zhou Qing asked: "Do you know this liquid?"

Huangquan Liquid, this name is quite appropriate.

Ao Xuanwei nodded, "Not only do I know him, I've also seen him before and met him before."

"This kind of thing is rare outside, and even the relevant information is rare, but if you enter a top Taoist school like Xuandu Temple, or worship a Huangquan monk as your master, then you can come into contact with this kind of thing."

"Oh?" Zhou Qing's mind moved, "From what you said, this Yellow Spring Liquid is actually not rare?"

"How should I put it..." Ao Xuanwei thought for a moment and replied:

"This is actually something similar to gold and silver, but it is used by high-level practitioners."

Zhou Qing blurted out a sentence when he heard it.

Please...collect 6_9_book_bar (Six//Nine//Book//bar)

"Ah? Isn't this just money?"

"Yes, it is money, the money used by high-level practitioners. The birth of this kind of money is also related to the practice of Huangquan monks."

Ao Xuanwei explained: "To cultivate in the Yellow Spring Realm, one needs to refine the Yellow Spring Power, but the specific process is very complicated, and there is also a saying about the Yellow Spring Power required in the Yellow Spring Realm."

"Most Huangquan cultivators, as long as they have the opportunity to enter Huangquan at the moment of breakthrough, will never be able to enter Huangquan again after the breakthrough. After all, it is not the human world, and it is not a place for living spirits to set foot."

Zhou Qing nodded. He knew this because Lu Qingmo had told him about it.

For most cultivators who have reached these two realms, there is only one chance in their lifetime, and they can only go there once after a breakthrough.

In this situation, the Yellow Springs Dragon becomes even more precious.

Other Huangquan monks can only go there once, but Zhou Qing can go there at will with the help of the Huangquan Dragon.

"However, being unable to enter Huangquan will not affect their cultivation."

"During the subsequent practice of Huangquan monks, although they are in the human world, they can directly draw Huangquan power from Huangquan."

"My father said that this is because every Huangquan cultivator who successfully breaks through has been recognized by Huangquan and has established a connection with Huangquan, so they can directly draw strength out of thin air through the connection between the two parties."

"As the Yellow Springs power travels from the Yellow Springs to the human world, a miraculous change will occur, producing Yellow Springs aura. You can regard these auras as derivative products of the Yellow Springs power, and what the Yellow Springs aura eventually condenses into is the Yellow Springs liquid you have obtained."

"Yellow Spring Liquid can be said to be a byproduct of the practice of Yellow Spring monks, but if they are willing, they can also actively condense the Yellow Spring Liquid."

Zhou Qing felt that the method of producing the Yellow Spring Liquid that Ao Xuanwei mentioned was similar to the way he obtained this liquid.

It turns out that this thing has such a nature.

"When a cultivator reaches the Yellow Springs Realm, the path changes greatly. This change is not only in the cultivator himself, but also corresponds to many skills and things related to the cultivator."

Ao Xuanwei continued, "Whether it is refining Huangquan Realm elixirs, magic tools, or making talismans and arrays, etc., it will involve Huangquan power. This kind of thing must be added to produce Huangquan Realm items."

"And Huangquan Liquid can meet this requirement. It also has a very small amount of Huangquan power, which can be used in many aspects."

"The items in the Yellow Springs Realm are different from the cultivators themselves. They do not need to be made in the Yellow Springs. The Yellow Springs Liquid can serve as the finishing touch. This even gives Yinshen Realm cultivators the opportunity to refine Yellow Springs treasures at a higher level."

"Of course, if you have the ability, you can enter Huangquan to refine what you want, which will naturally have the best effect, but you know that this is basically impossible."

"Because of the effect of Yellow Spring Liquid and its special production method, this thing has gradually become hard currency among high-level monks. Do you understand this?"

"I understand." Zhou Qing nodded.

It has a huge effect, and the production method is only mastered by Huangquan monks, and it is not difficult to make.

The essence of currency is a commodity that serves as a general equivalent. Yellow Spring Liquid is very valuable, and this value will exist forever and will never disappear. It can be used by high-level monks, so there is a huge demand for it.

So it becomes a currency, almost as a matter of course.

"In addition to Huangquan Liquid, there is also Biluo Liquid, which has a similar origin to Huangquan Liquid and can only be produced by cultivators in Biluo Realm."

Ao Xuanwei added: "In some trading places, the two precious liquids can be exchanged for each other, but the exchange ratio is extremely different."

"Most of the time, one drop of Biluo Liquid can be exchanged for dozens of drops of Huangquan Liquid. In rare cases, the ratio can even reach one hundred."

"Any treasure in the world that can only be purchased with Biluo Fluid is a rare treasure."

Zhou Qing pondered for a while and suddenly laughed.

"I thought I had found some treasure, but it seems that picking up a drop of Yellow Spring Liquid is no different from picking up a penny."

Ao Xuanwei smiled and said, "Although the Yellow Spring Liquid is of high quality, it does require a larger quantity to trade. At least ten drops are needed."

Zhou Qing asked: "Does the output of this thing during Huangquan monk's practice be high?"

Ao Xuanwei replied: "If you only look at the amount in one day, it's not high."

After hearing this, Zhou Qing immediately understood.

Not much can be produced in a day, but if a Huang family cultivator practices for decades, the amount of Yellow Spring Liquid produced will definitely be considerable.

After knowing the effect of the five drops of Yellow Spring Liquid in his hand, Zhou Qing did not feel depressed, but rather quite excited.

Five drops of Yellow Spring Liquid, it seems that he is indeed a little poorer.

But now, as long as he wants, he can produce Huangquan Liquid continuously like the Huangquan monk.

What's the difference between controlling the Yellow Springs Dragon and controlling a money printing machine? Others make money, and he prints money.
