Penglai Island is boiling.

The group of beasts have their own opportunities and are ecstatic. The black bear moves his muscles and bones, and his words and deeds gradually get closer to people, but he has never noticed it himself.

It looked at Yu Mo and said, "Penglai Island owes you a favor."

This sentence came from the bottom of my heart, and there was no demon beast to refute it, and even the direwolf rarely sang the opposite.

The vortex above Yu Mo's head also disappeared, and his meridians flowed with true essence. This time, he absorbed a lot of spiritual crystal energy, like a hungry person having a full meal.

In the sea of ​​​​air, a small cyclone appeared, like a cloud, and the center was the nine-petal lotus.

However, Yu Mo's goal was not achieved, and most of the energy just disappeared in the black prison, but the black prison was still dark and there was no response.

This greatly disappointed Yu Mo.

"The black prison is a bottomless pit, and I don't know how many spirit crystals it takes to fill it up."

Yu Mo and the black bear looked at each other and said, "Let's go down the hole first."

The beasts were so excited that they all wanted to find out the true content of the spiritual veins.

The mighty team went deep into the ground, and earth-shaking changes took place in the ground. The ice had long since melted and turned into bare stones.

The cave is winding, with nine and eighteen bends, the energy fluctuations in the air are still strong, and the light coming from the front is getting stronger and stronger, like the sun in the daytime.

Everyone's eyes widened, and their heartbeats increased. The black bear pointed to some digging marks on the cave wall and said excitedly: "These are all left by our ancestors. Back when they mined spirit crystals day and night, I don't know how much they sacrificed. It is their credit, but human beings sit back and enjoy it, and don't even give them a little bit of spiritual crystals."

The group of beasts was furious, and bursts of angry roars came out of their mouths.

Yu Mo's face did not change, Qiao Bin and others were terrified, the monsters still had a strong hatred for humans, they had recovered their freedom, and they didn't know how to fight back and take revenge on humans.

"what is that?"

Suddenly, the monster pointed at a pile of white bones and exclaimed.

Everyone's eyes were immediately attracted, and they gasped. It was actually a pile of bones, piled up into a hill. These bones are very huge, obviously not humans, but monsters.

"That's our sacrificed ancestor."

The monster was so excited, it roared up to the sky, and angered the sky.

The main road leader hurriedly jumped behind Yu Mo and distanced himself from the monster. Everyone found that the monster's gaze was not good.

The black bear gritted his teeth and said, "This matter has nothing to do with them. Let's keep a part of it and keep an eye on our ancestors. Don't disturb them."

Some of the monsters stayed, and the large army continued to move forward.

After this episode, the atmosphere became depressed, and it seemed that he was afraid of meeting the bones again.

As people wished, they reached their destination.

In a huge cave, I don't know where it stretches, but the cave is full of spirit crystals, diving into the hard rock, exuding a soft light.

"Spirit crystal!"

The monster cheered, his attention was immediately attracted, and his eyes were reluctant to look away.

Yu Mo was shocked. He saw a lot of spirit crystals, but he never knew the most primitive state of spirit crystals. Now he finally got what he wanted.

The spiritual realm is not a ripe fruit, it is all over the ground, just pick it up at will, they are embedded in the rocks.

Yu Mo stretched out his hand to hold the spirit crystal and tried to pull it out with his fingers, but found that the spirit crystal was as stable as a rock.

The other monsters did the same, and they all failed without exception.

"What's going on?" Everyone looked at each other, not knowing why.

Lingjing is in front of you, but there is no way to get it. Isn't this a boiled duck flying?

"Everyone, don't waste your energy."

The black bear stopped and said, "Spirit crystals need to be mined, not picked out at will. This is a hard job. If not, how could our ancestors have sacrificed so much. If there is such a good thing, human beings will not fake our hands. Do it yourself."

yes!

As soon as this statement came out, everyone suddenly realized that what they thought was too simple.

Yu Mo nodded thoughtfully and asked, "Then how can we mine spirit crystals?"

"Blood is the guide, and the spirit crystal can be excavated."

After all, as soon as it pointed out, a burst of blood spurted out and landed on the spiritual crystal and the rock. The blood disappeared completely, as if nothing had happened.

The black bear shot like electricity and directly pulled the spirit crystal out of the rock.

Everyone's eyes widened, tsk tsk amazement, it turns out that the mining of spirit crystals uses blood as a guide.

Yu Mo's heart was stunned, and he noticed the strangeness of the black bear. It looked solemn and seemed to be in pain, and asked quickly, "Do you mean that every piece of spirit crystal needs blood to be mined?"

The black bear nodded painfully: "Yes, every piece of spirit crystal is stained with the blood of our monsters."

"The blood of monsters? Can't the blood of other races be good?" Yu Mo heard the overtones and asked hurriedly.

The black bear sighed and said, "Why do humans enslave monsters and use us to mine spirit crystals, because only our monsters can do this, and no other race can do it. The blood of our monsters can soften this kind of rock. Thus, the spirit crystals were successfully mined.”

Yu Mo's heart trembled, and the others turned pale in shock. As for the anger in the eyes of the monsters, he said, "Bullying the beasts is too much, whoever we monsters provokes, just because our blood can soften blood, then we will be enslaved. Life after life?"

"Humans are shameless!"

"Revenge, defeat humanity!"

The monster raised its arms and shouted.

"What kind of rock is this, why is it so strange, it needs the blood of the monsters to soften it?" Yu Mo's fingers slid across the rock, it was indeed too hard to tell what material it was.

Hei Xiong said: "This is Xingyao Stone. It is the most exotic stone in the world. It is accompanied by spiritual crystals. There is no other place. It is indestructible. Except for the blood of monsters, there is no other way to soften it."

"so smart!"

Yu Mo's eyelids jumped, startled, there are such strange rocks in the world.

"It is precisely Xingyao Shi that our monsters have such a miserable fate. It is the broom star of our monster family, and the monster family hates Xing Yaoshi to the core." The black bear hit Xing Yaoshi with a punch, gritted his teeth. Said, and Xingyao Shi is safe and sound.

Yu Mo understands the black bear's mood and doesn't know how to comfort it.

The direwolf rolled his eyes and said, "Since the spirit crystals can only be mined by us monsters, then the spirit crystals belong to our monsters by nature. What does it have to do with humans, how can they be cheapened for nothing."

"That's right, the spirit crystal is ours!"

"Never for humans."

The black bear pressed down with his big hand and said, "The spirit crystal is here. Without our monster beasts, human beings would never be able to obtain it. We have to protect the spirit crystal from generation to generation."

"Guardian Spirit Crystal!"

"Guardian Spirit Crystal!"

The black bear said solemnly: "The blood of monsters is limited, and I can't tell how many spirit crystals there are on this Penglai Island. Even if our blood is drained, it cannot be fully mined. We must cherish it. Every piece of spirit crystal mined."

"In the past, human beings did not care about our lives, squeezing to the last drop of blood to mine spirit crystals. In the future, we will be the masters of Penglai Island. We can't do this. We want both spirit crystals and our lives, right?"

"right!"

Respondents gathered.

You Feng and Qiao Bin looked at Yu Mo at the same time, with solemn eyes. Mining spirit crystals has to pay such a huge price, can Yu Mo still get spirit crystals?
