"It's really difficult." Pharmacist Leng frowned.

Su Luo looked completely confused, and she quietly walked aside and asked Butler Xu: "What is the green-level crystal?"

Someone had never heard of the green-level crystal stone? Butler Xu was shocked and looked at Su Luo in surprise.

"What? Isn't it strange?"

Butler Xu nodded first, shook his head, and then said to Su Luo with a clear cough: "As we all know, there are two ways to quickly improve your cultivation. One is to concentrate on practicing, and the other is to absorb crystals. The first type of people often do not have crystals, so they must practice by themselves. It can be seen that crystals are very important for practitioners."

There is something like this? Su Luo frowned and said nothing.

No wonder she used to be a legendary waste, so she naturally knew nothing about the way of cultivation.

Mr. Xu also said: "Crystal stones are said to be divided into seven types according to their quality. Like their natural spiritual power, they are divided into seven types: red, orange, yellow, green, blue, and purple. However, there are very few crystal stones on the continent, and most of them are red, orange, yellow, and yellow, and very few of them in the green grade. As for the three types of blue, blue and purple behind, they are even rarer."

So, is it extremely difficult to find green-level crystals in a very short time?

"With the strength of the royal family, there should be materials in the Da Nei Warehouse, but it is very far from the imperial capital, and even if you sit on a dragon scale horse, it is too late." Butler Xu was so anxious that he was wandering around in the room.

Su Luo was also anxious.

What kind of crystal is this? Not to mention asking her to look for her, she has never seen her before.

Ling Feng suddenly stood up and ran out directly, leaving only a voice: "I'll go find it!"

Ling Feng took the token of King Jin to the city garrison, turned the inventory to the sky, almost causing trouble for the county magistrate to get three green-level crystal stones.

There are quite a few red, orange and yellow crystal stones, but these are the most important treasures for ordinary people to practice. For a sixth-level master like Nangong Liuyun, it is useless.

Ling Feng then went to the mercenary union and issued the task of acquiring green-level crystal stones.

A green-level crystal can be exchanged for 100,000 gold coins!

Such a redemption ratio is extremely high, so the whole city became lively and countless people began to convey messages.

Finally, Ling Feng returned to the manor with a truck of stones.

When Su Luo came out, he happened to see Ling Feng carrying a basket of stones weighing thousands of pounds and hurried in.

"Hurry, everyone has a basket of raw stones. If someone cuts out green-level crystal stones, he will be rewarded with tens of thousands of taels of gold coins!" Ling Feng was full of heroism.

With a command, the subordinates in the manor were immediately excited.

People do not punish heaven and earth for money.

What's more, this money is justified.

"These stones?" Su Luo couldn't help but feel a little stunned when his eyes fell on these stones. Why did she think these black stones look so familiar, and it seemed that they had seen them somewhere?

"These are the raw stones that produce crystal stones." Ling Feng explained in a low voice. "The raw stones are very strange. No matter how powerful a warrior is, they cannot see the inside of the raw stone at a glance. Some of these raw stones are just stones, some can cut out red crystals, some can cut out orange crystals, and yellow crystals and green crystals. No one can tell before they are cut out."
