Chapter 375: Intermediate Spiritual Stone

When it comes to the fourth-level formation, the Chen family had no access to it before.

When Chen Xianming saw the sixth-level formation of the Xing Sect today, he envied it in his heart and hoped that in the future, the Chen family would also have such a top formation.

Now, it is not advisable to be too ambitious for the time being. First, do what you can and build a fourth-level formation.

Bai Yingying did not hesitate at all and simply mentioned several formations that she was capable of setting up.

After some screening, Chen Xianming finally locked on a set of Nine Cauldrons Qiankun Formation.

This formation is a fourth-level medium-grade formation, with nine treasure tripods as the center of the formation.

If the nine tripods are combined into one, the power can reach the fourth-level medium-grade level, with both offensive and defensive effects, and the defensive power is greater than the offensive power.

This formation is flexible. Nine treasure tripods can also form a set of third-level formations with three treasure tripods, that is, three third-level formations, defeating the enemy layer by layer.

Because of the good effect and high flexibility of the formation, the price is also more expensive, with a total price of 250,000 spirit stones, of which the construction fee is 50,000 spirit stones.

This price is about 50,000 spirit stones more expensive than the formation of the same level.

When she learned that the Chen family wanted to build the Nine Cauldrons Universe Formation, Bai Yingying immediately nodded and agreed, and said that she would take care of her junior brother for Chen Qingfeng's sake.

Then there is no need to charge for the other expenses of going out of the mountain, only the reward for building the formation.

This seems to be not much money. If she is asked to go out of the mountain and live outside the Star Sect for a year, the maximum cost is 10,000 spirit stones.

But it can't be calculated like this.

Staying in the Star Sect with abundant resources, with a master to guide her from time to time, and high-level spiritual veins for cultivation, this is much better than staying in Lingjian Island.

A purple mansion cultivator, especially a fourth-level formation master, may not be short of these tens of thousands of spirit stones.

Many formation masters of the same level as Bai Yingying rarely accept invitations from cultivators outside the sect to make formations.

Even if the sect invites them, they can refuse.

Not to mention Bai Yingying coming out of the mountain and spending a year to help build the formation.

So Bai Yingying's coming out of the mountain this time really took care of Chen Qingfeng.

After negotiating the formation and the price, Bai Yingying issued an order to expel him, saying that she still had things to do and didn't have much time to delay.

After finishing the affairs at hand, she will go to Lingjian Island in two months at the latest.

Seeing this, Chen Qingyun and the other two said politely and left the cave.

On the way, seeing Bai Yingying's cold temperament, Chen Xianming smiled and joked.

"Qingfeng, it's not easy to get along well with your senior sister."

"When you have nothing to do, you should walk around more. It would be even better if you can learn a few moves of the formation."

"You have a good chance. You are the youngest disciple of the Red Spirit Patriarch, and you have such an amazing senior sister above you."

"In the future, whether it is Bai Yingying or the Red Spirit Patriarch, they will definitely take care of you out of affection."

"Don't let your senior sister prefer to help outsiders instead of you because you don't get along well with her. Remember what I said today. We all hope that you will live well in Xingzong."

As the clan leader, Chen Xianming's nagging habit has never changed.

Chen Qingfeng listened carefully and nodded heavily after the old clan leader finished speaking.

"I understand, clan leader. I will keep your words in mind today. I will visit my senior sister more often."

"In the next one or two months, when my senior sister is free, I will personally take her to our Chen family."

"Hahaha, it's good that you can understand it at once."

After completing this mission, Chen Qingyun and the others did not stay long.

That day, the two of them left Xingzong under the escort of Chen Qingfeng, and then took the Panlong and returned to Lingjian Island.

This trip took about a month, and there was another important thing to do next.

At the suggestion of Chen Xianming, Chen Qingyun temporarily dismantled the two demon-killing cannons on Lingjian Island and put them in the clan library.

Chen Xianming knew that this demon-killing cannon was not simple, and it was more powerful than the demon-hunting cannon of Xingzong. He didn't know how Chen Qingyun made it.

This kind of treasure, it's enough for the monks of the family to know, and they can keep it secret.

It's better to hide Bai Yingying if possible, and don't let Xingzong pay attention to the demon-killing cannon, so as not to cause unnecessary trouble.

In the blink of an eye, more than a month has passed. On this day, two figures broke through the waves in the sea and appeared outside Lingjian Island.

It was Chen Qingfeng, and Bai Yingying was here.

Bai Yingying finished her work and fulfilled her promise to come to the Chen family to build a formation, which is expected to take about a year.

"For the next year, I will have to trouble you, Brother Bai."

Chen Xianming smiled and arranged for Bai Yingying to stay on Lingjian Island.

Recently, Chen Xianming was very careful and specially built a cave with the same layout for Bai Yingying according to the appearance of the cave he saw in Xingzong, so that she could adapt quickly and live as comfortably as possible.

In the next few days, Bai Yingying carefully explored the terrain, environment, size, etc. of Lingjian Island, and began to discuss with Chen Xianming to purchase various formation materials.

A fourth-level formation requires a lot of materials.

A total of 167 kinds of materials, of which the most used are medium-grade spirit stones, which require 99 pieces.

Spiritual stones are divided into four levels: low-grade, medium-grade, high-grade and top-grade. The higher the grade, the richer and purer the spiritual energy contained, and the more beneficial it is for cultivation.

The exchange ratio between these four types of spiritual stones is one to one hundred.

For example, one hundred low-grade spiritual stones can be exchanged for one medium-grade spiritual stone.

According to this ratio, theoretically, 10,000 low-grade spirit stones, or 100 medium-grade spirit stones, can be exchanged for one high-grade spirit stone.

But in the Xinghai cultivation world, almost no one would exchange high-grade spirit stones for 10,000 low-grade spirit stones.

This is because high-grade spirit stones are extremely precious. They can not only serve as the core energy of high-level formations, but also participate in the refining of high-level spiritual pills and life magic weapons.

Using it to practice, only one piece is needed to help the Purple Mansion cultivators condense the golden pill, provide rich spiritual energy nourishment, and increase the chance of breakthrough.

There are more than 20 spirit stone mines discovered in the Xinghai, which are basically controlled by the five major sects.

However, the output of high-grade spirit stones in these spirit stone mines is very few. Every time one is discovered, it can be favored by the top leaders of each sect.

As strong as the Xingzong, the high-grade spirit stones in its hands are less than 100 pieces, and each piece is like a treasure and will not be circulated to the outside.

The other four major sects have even fewer, all of which are used for their own construction and training of strong people.

According to the current rules of the Xinghai Immortal Cultivation World, anyone who has a top-grade spirit stone can find the four major sects or exchange it for a purple mansion crystal in Xingzong.

The value of this top-grade spirit stone is no longer measured by the number of spirit stones, but as a high-level resource, it is circulated among the purple mansion peak cultivators and even the golden elixir cultivators.

How can it be exchanged for medium-grade or low-grade spirit stones?
