This was the first time he had heard the name of this crystal stone, and he couldn't help but ask curiously:
"What is Black Fire Crystal?"
Xiaoya was stunned for a moment and looked at Zhou Yu, as if she was surprised that he didn't know what the Black Fire Crystal was.
"Don't you know?"
Xiaoya suddenly remembered that Zhou Yu and his friends were from other places, and then she suddenly realized and said:
"That's right, you are not from the Frozen Land."
"Black Fire Crystal is a type of crystal that is unique to our frozen land. It is extremely rare. Inside the crystal is a powerful flame energy that can be used to extract any herbal medicine."
"It's almost a must-have for refining high-level elixirs here."
Black Fire Crystal. This name made it hard for Zhou Yu not to think of the black fire that had become one with himself.
Because of this, he was extremely curious about Black Fire and continued to ask:
"Since this is a crystal stone that is unique to your frozen land, there must be other ways to obtain it. How can it be so rare?"
Xiaoya sighed, and an expression that shouldn't appear at her age appeared on her face.
It seems like there is no other way after careful consideration.
"There are quite a few black fire crystals in our frozen land, but they are all controlled by the three major mercenary groups. They don't sell black fire crystals on weekdays, but only auction them at auctions, and each piece is sold at a sky-high price."
Zhou Yu nodded, it turned out to be hunger marketing.
Control the quantity of black fire crystals sold.
Even if there are a lot of black fire crystals, they are rare commodities outside, so naturally they cost a lot of money to buy.
In particular, the black fire in the black fire crystal can also extract the medicinal properties of high-level herbs.
This is an even more fatal attraction for alchemists.
Therefore, it will cost a lot of money to buy it.
When Zhou Yu was still in the Great Zhou Kingdom, some unscrupulous merchants deliberately hoarded grain during famines and then raised prices.
The two are almost the same thing.
Three major mercenary groups...
Zhou Yu seemed to be thinking about something.
Black Fire Crystal, if there is a chance, he would like to see if it has any connection with the black fire in his body.
Xiang Xiaoya returned to the cave to rest.
Zhou Yu continued to practice alone in the carriage.
In the middle of the night, he suddenly opened his eyes and saw two blue lights in the distance, staring at him like eyes.
Zhou Yu frowned, thinking of the Night Demon.
Goering, the old man who had given Zhou Yu a blanket, had said before that there were night demons in the frozen land at night.
The night demon can be classified as a demon beast.
They only appear on cold nights. They have blue eyes and no physical form, but they can cause substantial harm to people. It's very strange.
But the strange thing was that Zhou Yu could sense that the night demon had been staring at him for a long time, but had no intention of taking action.
This confused him very much.
The night demon seemed to be afraid of something.
Zhou Yu's perception covered an area of 100 meters in radius, but he did not sense any other existence.
After staring at the night demon for a while, Zhou Yu discovered that the night demon had left.
He was not planning to chase after him. Since the other party was not planning to cause trouble for him, Zhou Yu was not planning to cause trouble for no reason.
Get a good night's rest and then continue on your journey.
But what Zhou Yu didn't expect was that the Night Demon did not leave, but returned to find help!
But after a moment, Zhou Yu discovered that he was surrounded by dozens of night demons.
A dozen pairs of blue eyes flickered in the darkness.
Suddenly, Zhou Yu discovered a pair of eyes emitting blue light disappearing into the darkness.
When he appeared again, he was at the entrance of the cave!
Zhou Yu's face changed, he took out the red-refined heavy sword and slashed it, and a sword energy shot out.
The white light briefly illuminated the sky for a moment.
Zhou Yu also saw the specific appearance of those night demons.
Except for a pair of blue eyes, all other parts are transparent.
Like a kite, floating in the air.
Moreover, they were extremely fast. When Zhou Yu's sword energy was about to fall, the night demon disappeared into the night again.
Zhou Yu had a solemn expression. These night demons could actually make their bodies disappear for a short period of time, and could not be captured by the naked eye.
Out of caution, he stood directly at the entrance of the cave to block the group of night demons.
Zhou Yu originally thought that this group of night demons would attack him one after another, after all, there were so many of them.
But what he didn't expect was that the moment he stood at the entrance of the cave, all the night demons stopped moving.
Stop and watch!
Zhou Yu was puzzled. The scene before him was really unbelievable.
He was sure that these night demons were coming for humans.
Goering once said that the Night Demon needs to eat and suck human blood.
If there is no human essence and blood to absorb, they will look for monsters.
It is also because of this that in the dark night in the frozen land, most monsters will shrink into their nests and dare not move, for fear of encountering a night demon that has not found people.
But why are these night demons not moving
Zhou Yu did not dare to be careless. He tentatively sent out a sword energy and attacked a night demon.
The white sword energy shot out and arrived in front of the Night Demon in the blink of an eye.
Zhou Yu widened his eyes and saw that the sword energy was about to hit him, but the night demon's body suddenly disappeared.
The sword energy missed directly.
And then, the Night Demon's body reappeared in its original position!
Zhou Yu frowned, the sword attack was useless.
He tentatively used the Sword Star Sea to lock onto these night demons.
Under Zhou Yu's control, a sword appeared out of thin air at the location of a night demon.
Got it!
A sword gleaming with light appeared in the body of a night demon.
But then Zhou Yu was dumbfounded. The Night Demon didn't react at all.
It was as if it didn't exist at all, and the sword just appeared out of thin air!
Zhou Yu put the sword back, and his expression became extremely solemn.
His attacks were useless against the Night Demon.
But Zhou Yu still didn't know what the attacks of these night demons were like.
The unknown is the most dangerous.
Although he didn't know why the night demons didn't attack him now, Zhou Yu couldn't guarantee that these night demons would not attack him forever.
Just as Zhou Yu was thinking about countermeasures.
Suddenly, several screams were heard in the distance.
A dozen night demons were immediately attracted and disappeared.
Zhou Yu hesitated for a moment, and immediately prepared to follow and take a look.
If he could see how the Night Demon attacks, he could be prepared!
However, out of caution, Zhou Yu set up a puppet sword formation at the entrance of the cave before leaving. If any bad guys appeared, he could stop them and inform the people in the cave.
Zhou Yu quickly caught up with those night demons.
Soon, more than a dozen figures were seen in the night being attacked crazily by the Night Demon.
Zhou Yu widened his eyes. The attack methods of these night demons were very special.
They will make a cry that is very captivating and if one is not mentally strong, he or she can be easily controlled.
Then he turned into a walking corpse, allowing the night demon to suck his blood!
"Wait, isn't that someone from the Lin family?" Zhou Yu was stunned. Among those dozen people, there was actually someone from the Lin family.
He saw it when he met Lin Qian!
