"Spirit stone?" Su Yi was stunned.

Spirit stones, simply put, are stones rich in spiritual energy, which can often be used to refine magic weapons, provide energy, and so on.

They are the equivalent of Xianxia and the currency of the fantasy world.

In the same way, it can also allow the practitioner to absorb the spiritual energy within it, speed up the recovery of true qi, and cultivate.

"Do you have spirit stones?" asked Su Yi.

"Nope. Bai Fei shook her head.

Well, this point is also within the scope of Su Yi's prediction.

The place where the Cloud Rabbit clan lives is definitely the edge of the edge of the demon clan, and even in such a small place, they are also the existence of being beaten, how can there be such a thing as a spirit stone?

"If not, what's the point of saying it?" Su Yi shook his head.

If it was something that could not be obtained, Su Yi could also think of many ways to strengthen himself.

The simplest, give Su Yi a heaven and earth spirit treasure level spirit fruit, and his absolute strength will increase greatly.

Or there is a strong man at the level of the demon king, who only has one breath left and falls in front of him, he slaps the demon king to death, and the evolution points obtained are definitely enough to meet Su Yi's requirements.

But what is the difference between this approach and nothing?

Dreams can be had, but the way to achieve them is not by sleeping and dreaming!

"No, we have a spirit stone mine here. Bai Fei blinked his eyes and said, "If the king is lucky, he may be able to dig up some spirit stones casually." ”

"Spirit Stone Mine?!" Su Yi's spirit came all of a sudden.

If the spirit stone is money, the spirit stone mine is the money printing machine!

With a money printing machine, are you still afraid of running out of money?

Immediately, Su Yi asked about the situation in detail.

Then he realized that the spirit stone mine was actually an ultra-small spirit stone mine, which was not taken into account by the big forces, and he didn't bother to mine it if he knew it.

Of course, in a small place, this kind of spirit stone mine is still very valuable.

The spirit stone mine here is controlled by a large demon clan, and the spirit stones produced will sometimes exchange spirit fruits with the surrounding demon clans.

Su Yi squinted his eyes and fell into deep thought.

"Lingshi Mine...... Bai Fei, go. ”

"Well, King, what are you going to do?" Bai Fei looked at Su Yi strangely.

"Go to the owner of the Spirit Stone Mine. ”

Su Yi said calmly.

......

The Spirit Stone Mine Cave is about three hundred miles away from the territory of the Cloud Rabbit Clan, spanning the territory of the five demons.

Su Yi did not take Bai Fei directly over, but chose to expand his territory all the way.

He knew with his ass that the value of the spirit stone was very high, there were no competitors around, it was a monopoly business, and it was estimated that the price would be very expensive.

The spirit fruit is also a necessary thing for Su Yi's strength, even if he is willing to take out the spirit fruit in exchange for the spirit stone, he will definitely not be able to take out too much.

And the spirit stone ......

One or two pieces, I'm afraid it may not be enough.

Su Yi looked into the distance, and secretly had a plan in his heart.

For the next half month, Su Yi has been on the road.

The five demon clans were defeated by him one after another, but this time because of the spirit stone mine, Su Yi only recovered from his injuries, and immediately went to the next demon's territory, instead of killing most of the surrounding beasts before attacking.

In addition, after upgrading the two skills, Su Yi's strength has also increased a lot, and the consumption of time has naturally slowed down a lot.

Half a month later, he finally came to the vicinity of the spirit stone mine.

"King, the cave in front of you is the Spirit Stone Mine. Bai Fei followed next to Su Yi and said softly, looking at Su Yi with a bit of longing in her eyes.

Don't get me wrong, she doesn't think Su Yi is beautiful, in fact, the aesthetics of felines and rabbits are not the same thing at all.

After the transformation is completed in the future, the demons can still be used for the aesthetics of the human race, but now the beasts that have not transformed are not good-looking.

What she is looking forward to is Su Yi's strength!

The demon clan has always been respected for its strength, and Su Yi has killed many demon clans in a row during this time!

The demons are scattered all over the place, and the flow of information is not large, but she also knows the strong people around her!

And these strong people don't even have bones anymore!

"It's so strong......" Bai Fei's eyes flashed with adoration.

Although it is said that the birth of mixed blood, many of them are the result of one party forcing one party.

But there are quite a lot of mixed bloods, which are the products of the weak demon race, the worship of the bloodline of the strong race, and the initiative to dedicate themselves!

The demon clan's worship of strength comes from the bottom of his bones......

"Ahead......"

Su Yi nodded and walked forward slowly.

If he could, he didn't want to cause too much trouble - the power that could occupy a spirit stone mine was definitely not weak.

The upgrade was imminent, and he didn't want to make any problems.

Of course, if it really doesn't work......

......

After walking a few hundred meters, Su Yi saw a big mountain.

The mountain peaks are high and the aura is abundant - even if you don't have a spirit stone mine, practicing here is a pretty good choice.

Of course, there is a Lord here.

Su Yi raised his head, looked at the dark cave, and said loudly.

"I want to exchange it for some spirit stones. ”

Although he has not yet been promoted to a demon, his voice is not small, and soon after entering the cave, he saw a bear walking out leisurely.

It was a bear larger than three elephants, tall and stout, like pillars, and its hair stood on end, making its already huge size look a little bigger.

This is the demon who occupies the spirit stone mine, the Thunder Bear Clan.

As soon as he came out, he glanced at Bai Fei disdainfully, and snorted in a nasal voice, full of contempt.

Then he looked at Su Yi.

"You're the cat you said was active lately......"

It has been nearly two months since Su Yi began to attack the surrounding demons, and although the news circulation of the demon clan has been relatively backward, his news has gradually expanded and spread.

Killed several demonic beasts!

If it weren't for the demon's extraordinary attachment to the territory, I'm afraid he would have considered leaving this place a long time ago.

However, that's a weak demon!

And not the demon in front of you!

"A little beast, you also want spirit stones?" Thunder Bear snorted disdainfully: "Okay, I'll do this deal." ”

With that, he turned and walked into the cave.

Then after a few minutes, he came out again, and threw his wide paws on the ground.

"There are five spirit fruits for each spirit stone, you have to buy a few. ”

However, Su Yi's face was extremely ugly.

Spirit stones vary in size, but after countless years of evolution of human beings and demon systems, regulations on spirit stones have been formulated.

Not in terms of large and small wheels, but in terms of Reiki.

If you have a lot of spiritual energy, make it smaller and count it as a spirit stone.

If the spirit stone with low spiritual energy is made larger, it will be counted as a spirit stone.

It's good to maintain a balance overall.

But the spirit stones that the thunder bear in front of him did throw were all broken spirit stones!

There were a total of seven spirit stones in front of him, but they were all small and a little bigger than the glass beads that Su Yi played with when he was a child.

There are also more and less aura, which is obviously far inferior to the standard spirit stone.

Even when they add up, they may not be comparable to a spirit stone.

"That's all, you're going to offer five spirit fruits?" Su Yi's eyes suddenly turned cold.

"Do you like to buy it or not? Lei Xiong snorted disdainfully: "And I can say it, according to my rules, even if you don't buy it, you have to take out five spirit fruits for me!"

"Lao Tzu worked hard to get out of the cave, but it took a lot of effort!"
