Chapter 7572 The Best Black Spirit Stone!

"We call these spirit stones black spirit stones, which are used by monsters for cultivation. The energy inside is very pure, similar to the blood spirit stones we usually use. Usually, these spirit stones are not converted into credits, but they can be exchanged.

One black spirit stone can be exchanged for two blood spirit stones, which is equivalent to doubling the value. "

Instructor Jin looked at the black spirit stones in front of him, and suddenly his eyes stopped on one of them, "Among all of you black spirit stones, there are top-quality black spirit stones?"

"Extreme black spirit stone?"

Baili Hongzhuang and the two were slightly stunned, and their eyes fell on the black spirit stone Mentor Jin was pointing at.

I didn't notice it if I didn't look carefully at first, but now I noticed the difference when I took a closer look.

The mention of this black spirit stone is larger, and its color is darker. After careful perception, it is found that the energy contained in it is much stronger than other black spirit stones.

"This top-grade black spirit stone is different from ordinary black spirit stones, it is a spirit stone of another level.

In this monster battlefield, black spirit stones were not so much before, but top-quality black spirit stones were very valuable.

Because the energy it contains is more pure and absorbs faster, practitioners can absorb it directly. With this top-grade black spirit stone, your body tempering speed will be much faster. "

"Then how many credits can this top-quality black spirit stone be exchanged for?" Di Beichen asked.

"One hundred credits."

"One hundred credits?"

Baili Hongzhuang was taken aback for a moment. As far as she knew, blood spirit stones could not be exchanged for credits at all.

However, just one top-quality black spirit stone can be exchanged for 100 credits, the gap between the two is too great.

"Even if the energy of the best black spirit stone is more pure, the gap is not so big, right?"

"Rare things are more expensive, and this top-grade black spirit stone can greatly speed up your breakthrough speed, and your entire body will be strengthened. Even high-grade immortals, this top-grade black spirit stone is also useful." Jin Tutor said with a light smile, "It's hard to see this thing below the Fifth Grade Domain."

Hearing this, Baili Hongzhuang also understood that there are very few below the fifth grade domain, no wonder there is such a price.

"You have a lot of useful things here. The energy liquid can be exchanged for 300 credits. There are a lot of these medicinal materials, which can be exchanged for 500 credits. There are also some monster furs here, which can be exchanged for 500 credits. Three hundred credits, a total of 1,600 credits.

As for this top grade black spirit stone, do you want to change it? "

Baili Hongzhuang shook her head slightly, "No more."

They already have 1,600 credits, which is enough for the current situation. There is only one top-grade black spirit stone, and they can try it to see what kind of effect it has.

"Okay, I'll replace all the rest of the stuff for you, 800 credits per person."

"Thank you, Teacher Jin."

Baili Hongzhuang showed a smile on her face. From the first 20 credits to the current 800 credits, the harvest this time is indeed very good.

The monsters brought back by Li Ruiyang can also be exchanged for some credits, which add up to a lot of credits. The cultivation resources exchanged by these credits in the resource room are enough for them to break through to the third-grade realm or even higher.

"Bei Chen, you are indeed here!"

Li Ruiyang and Cai Mingshu happily walked in front of them, "I came to you as soon as I heard the news of your return. You two are really good enough to go to the Fourth Grade Domain?"
