Generally speaking, most of the elixirs and spiritual patterns circulating on the market are third-grade or lower.

For example, a first-grade elixir corresponds to a warrior in the body refining realm, and the price of one elixir ranges from ten to dozens of jade pieces.

Second-grade elixirs are suitable for warriors in the Qi Gathering Realm, and their prices range from dozens of jade bis to a hundred jade bis.

The price of a third-grade elixir corresponding to a Danyuan realm warrior would reach around a thousand pieces of jade.

And if it is a higher-level fourth-grade elixir, corresponding to Tiangang realm warriors, the price of the elixir will rise sharply, reaching an astonishing tens of thousands of jade bis!

The reason why fourth-grade elixirs are so expensive is because there are few alchemists at this level, the cost of fourth-grade elixirs is high, and most of these elixirs are in the hands of various forces.

Less circulation to the outside.

Of course, elixirs of the same level are also divided into four grades: low grade, medium grade, high grade, and special grade.

The higher the grade of the elixir, the more amazing the effect will be, even doubling the effect.

For example, if a warrior encounters a bottleneck in his practice, he cannot break through the bottleneck with low-quality elixirs, but if he uses medium-quality elixirs, the chance of breaking through the bottleneck will be greatly improved.

However, generally speaking, low-level elixirs are more common, while medium-level elixirs are rarer.

Especially fourth-grade elixirs, if they are medium-quality elixirs, they will generally only appear among the Imperial Court-level forces, and will be rewarded to those highly talented Tiangang realm warriors for consumption and practice.

If it is a top-grade fourth-grade elixir, then if you want to practice with this level of elixir at the level of Tiangang Realm, I am afraid that only the saints and saints in the Holy Land have the qualifications.

It can be seen from this that if a high-quality fourth-grade elixir were to appear, it would definitely cause a huge sensation.

But if Chu Chen wanted to raise tens of millions of jade pieces in three days to buy the silkworm grass in the hands of the magician, he had no choice but to take an unusual path.

Although Moyu City is not big, there is an auction house.

It just so happens that due to the recent turmoil, many disciples from big forces have come here. If there is a bid for a high-level fourth-grade elixir in the auction house, those young masters from big forces will definitely be willing to spend a lot of money for it.

After all, pills of that level are something that only saints and saints are entitled to enjoy!

As for the special fourth-grade elixir, Chu Chen was not absolutely sure of refining it. Unless he was lucky, he might be able to refine one or two.

But even if it is refined, Chu Chen will not sell special elixirs. After all, elixirs of this level come with a characteristic, which is to unlock the power of the human body's secrets!

He had sold a special body-tempering elixir before. Since it was only a first-grade elixir, it didn't matter. Even if he got lucky and opened the human body's secret treasure, the improvement he got was minimal.

But the fourth-grade special elixir is different. Even if opening the human body's secret treasure is a matter of probability, and the probability is very low, Chu Chen is still prepared to keep it for his own use.

Because I don’t want any accidents to happen.

So before refining the elixir, Chu Chen first used spiritual patterns to carve out a spiritual formation in the room of this inn that would isolate all breath and soul power perception.

There is a lot of material in his Najie, because many people have died in his hands recently.

At the same time, Moyu City is located near Yunmeng Ridge, and Yunmeng Ridge is rich in various third- and fourth-level elixirs and spiritual materials. Even if you need anything, most of them can be purchased here.

Under the temptation of Jade Bi, Xian'er naturally became Chu Chen's assistant.

"With this spiritual pattern, if you encounter danger, input your true energy to activate it directly. At the same time, I can immediately sense your location."

After making a list and handing a ring containing a jade to Xian'er, Chu Chen ordered.

Before everything was ready, the first thing Chu Chen engraved was a fourth-level spiritual pattern.

After all, there is a mixed bag of fish and dragons in Moyu City. If this girl Xian'er encounters danger when she goes out to buy materials for him, with her first-level Danyuan realm cultivation, she may not even have the ability to protect herself.

"Know it!"

Xian'er rolled her eyes at Chu Chen and ran out.

Then, time passed quietly and unconsciously.

Within two days, Chu Chen had no intention of leaving this inn.

Wuying Tower was very efficient. In less than a day, someone came to the door of Chu Chen's room.

Xian'er went out to buy materials, so Chu Chen went to open the door in person.

A very ordinary-looking young man stood outside the door.

"Sir, this is what you want."

The young man handed over a box, then turned and left without saying a word.

Chu Chen closed the door and returned to the room.

After opening the box, he saw the letter inside.

Picking up the letter, Chu Chen started reading it.

The record on the letterhead is exactly the information about the Chu family in Baicheng, Han Dynasty in the Qin Dynasty. An intelligence mission like this is simply too simple for Wuying Tower.

However, even for such a simple task, Wuying House still charged a commission of two million jade, which was also Wuying House's cheapest information base price.

According to the description on the letter, everything in the Chu family was normal and developing steadily. They had established a cooperative relationship with the Qin royal family and took over half of the industries that used to belong to the three major families.

Seeing this, Chu Chen's anxious heart finally relaxed.

As long as the family is fine, he will feel at ease.

Because this means that his matter does not involve the Chu family.

In addition, there is another piece of information mentioned in the letter, which may be additional information.

That is, something happened in the Qin State. A place called Qingzhou was slaughtered, and an unknown number of people died.

"Taiyi Holy Land!"

Chu Chen's eyes showed a cold light, although he was not a person who cared about other people's lives and deaths.

But this statement from Taiyi Holy Land still made him feel murderous intent.

Because he didn't even need to think about it, because it must have been because of Taiyi's Heaven Seizing Formation, which had implicated people in the Qingzhou area.

The Chu family had escaped disaster. It is estimated that no one from the Taiyi Holy Land investigated this matter. Otherwise, if they knew that the Chu family was also a family from Qingzhou in the past, they might have destroyed Hanbaicheng as well.

After a while, Chu Chen finally calmed down the murderous intention in his heart.

Because no matter how strong his murderous intent is, with his current ability, he cannot shake a behemoth like Taiyi Holy Land.

At least for him now, Taiyi Holy Land is absolutely unshakable.

"Sooner or later, I will come personally and conquer everything!"

Chu Chen raised his hand and waved, and the mysterious cold fire emerged and burned the letters.

Then he picked up the last piece of paper.

There is very little writing on this piece of paper, only a few short words.

"Special intelligence mission, millions of high-grade jade!"

Seeing these words, Chu Chen's face suddenly turned gloomy.

Because he knew that the content mentioned above was related to the crazy woman who took Su Xiaorou away.

"Special intelligence category?"

Chu Chen's eyes narrowed. He certainly knew that the people who could be included in the special category in Wuying Tower had extraordinary origins.

Based on the current Wuxuan Continent, at least one must be a strong person above the Nirvana realm to be eligible to be included in the category of special intelligence.

If you want to obtain such information, you need to contact Wuying Tower and bring out millions of high-grade jade to get clues.

A piece of high-grade jade is worth 10,000 yuan as much as an ordinary low-grade jade!

In other words, this piece of information alone is equivalent to the value of hundreds of millions of jade!

"Chi!"

The faint blue flame burned the last piece of paper to ashes.

Chu Chen began to continue refining elixirs.

Although his cultivation level has not yet reached the Tiangang realm, he has the ability to refine fourth-grade elixirs with the Xuan Cold Fire that has been promoted to the fourth-grade spiritual fire level.

Coupled with the alchemy techniques and experience he has mastered, it is not difficult to refine high-quality elixirs.

"Xian'er's cultivation level has just broken through to the first level of alchemy. He needs third-grade elixirs to improve his realm and assist in his practice. You can first refine a furnace of third-grade elixirs to test the waters."

Looking at the materials on hand, I saw that there were not enough materials for the fourth-grade elixir, but there were more than enough materials for refining the third-grade elixir.

Chu Chen was refining a very common third-grade elixir called Ning Yuan Dan.

As the name suggests, it is an elixir that condenses true energy.

In the realm of body refining, martial arts practitioners store the vitality of heaven and earth in their bodies to strengthen their skin, flesh, muscles, and bones.

The Qi Gathering Realm is to condense the vital energy of heaven and earth into true energy.

When you reach the Alchemy Realm, you have to condense it into true essence.

The speed of absorbing the same amount of heaven and earth energy and condensing the true energy is far less than the speed of condensing the true energy, and the amount of condensed true energy is also very small.

Therefore, the cultivation speed of Danyuan realm warriors will be much slower.

Therefore, if there is Yuan Ning Dan to assist in cultivation, the efficiency and speed of refining the energy of heaven and earth into true energy will be greatly improved.

And if you take Yuan Ning Dan and Zhuang Yuan Dan together, the effect will be doubled.
