"Can you see if there is anything in the Black Stone?" Luan Baifeng looked at Yang Kai in shock.

The two of them mined 100 black stones in the past three days. Most of them were just a glance and discarded them. In the end, twenty-seven pieces were left, but all of them were harvested, without exception.

This situation undoubtedly illustrates some things.

"This is impossible!" Luan Baifeng grabbed a black stone that was thrown by Yang Kai aside with some disbelief. The black stone was not big, only the size of a palm, and activated the power of the world. It dissolved the black stone in less than a moment, and then there was nothing inside.

"Can you really see the situation inside the Black Stone?" The facts were in front of you. Luan Baifeng had to believe it now, "What kind of pupil technique do you have?"

Yang Kai did not answer, but frowned.

Although I obtained twenty-seven cultivation resources, and the facts proved that Luan Baifeng was right, the resources produced on the slightly deeper ore stars were indeed higher than those on the outside. Three of the twenty-seven products I got now are of the fifth grade.

Unfortunately, there is no sixth grade, let alone the sixth grade Yin and Yang are good!

Luan Baifeng was inexplicably excited: "If you can really see through the internal situation of Black Stone, it will greatly save time and improve output efficiency."

But Yang Kai shook his head slowly: "It's too slow!"

Luan Baifeng was surprised: "You are still slow in this way? How can you try to be fast?"

Yang Kai said: "It doesn't make much sense for you and me to work here for three days before they get such a little bit of things."

Luan Baifeng frowned and said, "If you want the sixth-grade Yin and Yang, it depends on luck. Do you really think that the mineral stars are full of things you want?"

"Of course I haven't thought so." Yang Kai frowned, "but this is a bit different from what I expected."

Luan Baifeng pondered for a moment, pointed his hand into the distance and said, "Maybe you can go to the deeper ore star to see. The one under our feet is the farthest place that the mine slaves under my hands have reached so far, and I have never been to the deeper ore star there. The black stones bred by the mine stars there may be higher quality."

Yang Kai looked in the direction she pointed, and saw countless mineral stars of all sizes in the void. I felt for a while and shook my head and said, "No need, I just rely on the power of you and me. The mining speed is too slow. If I want to get all the things I need, I don't know if I want to get the year of the monkey and horses."

"This is not possible, that is not possible!" Luan Baifeng was inexplicably angry, "Or you go back and bring all the mine slaves under my command to mine together. With your supernatural powers, no matter how poor their cultivation level is, they will not die in a short time, and they will always play some role."

Yang Kai shook his head when he heard this, Luan Baifeng's proposal was even more unrealistic.

His magical power is enough to protect the two of them, and it is OK to have dozens of people, but it is impossible to protect all the mine slaves, and it is too much to maintain for a long time. What's more, he can't stay here forever to protect the mine slaves.

I don’t know what’s going on in the void now, so he needs to try his best to go back and stay in charge!

I already have ten people's resources, plus three of them already on the other side of the void, which can now meet the needs of thirteen people to be promoted to the sixth grade. Maybe I can go back first and then wait for the mining of the Black Prison. Maybe I have good luck and I can get more resources I need.

However, this idea only went around in his mind for a while, and Yang Kai rejected it.

Luan Baifeng herself also said that the materials she had hidden in her hands were basically mined from the ore star under her feet in her early years. The chances of those ore stars outside could produce sixth grades.

After sighing, Yang Kai felt that what he was thinking was still too simple.

Just as he was about to return home, Yang Kai suddenly stopped and looked up into the void.

Luan Baifeng looked suspiciously. As she observed her words and expressions, she saw Yang Kai frowning at first, then her expression moved, as if she had remembered something and was greatly refreshed.

"You..." Luan Baifeng looked at him steadily.

Yang Kai grinned and said, "Yes, it's too troublesome for mine slaves to bring them here. I can't stay here to protect them all the time, but we can bring a mine star back!"

Luan Baifeng was startled by his whimsical thoughts and glared: "Take a mineral star back?"

Yang Kai expressed his expression excitedly: "There is no strange atmosphere on the periphery of the Black Prison. At least there is no place where you live on weekdays. If you can bring the deep mineral stars there, you can mine them unscrupulously, and you don't have to worry that your world power will continue to dissipate."

"Are you crazy?" Luan Baifeng looked at Yang Kai like a fool, "Take one back and I'll take a look."

"How can you know if you don't try it?" Yang Kai was ready to watch and kept watching. "When I came, I noticed that the mineral stars in this black domain are big and small. We naturally don't need to rely on those that are too big, and we probably can't carry them, but if we find one that is similar, we should be able to bring them back."

"Aren't you kidding me?" Luan Baifeng finally confirmed that Yang Kai was really playing, and she was stunned.

"Who is joking with you!" Yang Kai said, and then he urged the power of the world to run towards the depths wrapped around Luan Baifeng.

Since I decided to bring a mineral star back, the deeper it is, the better, because the deeper the mineral star, the richer the materials it contains and the higher the grade.

As he walked along the way, Luan Baifeng's expression was dull.

She still didn't keep up with Yang Kai's mind. She had been in the Black Prison for countless years. She never thought about bringing the mineral stars in the deep black Prison back to the periphery. It was not that she didn't dare to think about it, but that this was something that she could not do at all.

Even if she is a sixth-grade Kaitian and is strong, it is difficult for her to stay in this depth for a long time. What's more, the mineral stars are generally extremely huge, so who can take them away?

But Yang Kai not only thought so, but also prepared to do it!

On the way forward, Yang Kai kept muttering: "This one is too big and probably can't be taken away. This one is a little smaller. Even if it is taken back, it will not take long for it. It will not be worth the money. Why is there nothing big or small?"

Luan Baifeng was a little annoyed by his muttering, and couldn't help rolling her eyes.

I don’t know how long it took to fly deep into the black realm, but Yang Kai had not found a suitable target. At one moment, a strange aura suddenly penetrated the towering and eternal defense barrier and instantly wrapped the two of them. Yang Kai and Luan Baifeng groaned together, feeling that the power of the world in their own small universe was like a flood, roaring and passing out!

Luan Baifeng's face changed drastically!

Yang Kai was also inexplicably frightened, and quickly stopped and retreated thousands of miles backwards!

The abnormality of Xiao Qiankun disappeared instantly, and the aura that wrapped around the two people also disappeared at the same time.

The two looked at each other with lingering fear, and Luan Baifeng said, "What's the situation?"

Yang Kai slowly shook his head, saying that he didn't know it, but at that moment, his own small universe's foundation had passed away by about 10%.

Although I don’t know how Luan Baifeng is, the situation should be worse, because the woman’s face is slightly pale and her breath is weak, which is obviously a huge consumption.

"Your magical powers can't resist the invasion of that aura?" Luan Baifeng asked in surprise.

Yang Kai said in a deep voice: "If you can't resist, the great power of the world in our little universe should still be passing away."

"But just now..." Luan Baifeng said and had a cold war. The feeling was so terrifying that she could not resist and was about to be drained.

Yang Kai raised his eyes and looked into the distance: "There should be a critical point. After passing that critical point, even my magical powers will be difficult to guard against the power of this black domain!" He shook his head and said: "You can't go deeper, this place is the limit. If you go deeper, we will all die!"

I was secretly shocked. What is the strange aura in the black domain? I couldn't even resist the magical secret technique condensed by the essence of the Immortal Tree. You must know that his towering evergreen secret technique can be peaceful even if it is shuttled through the magical power of the Shadowless Gangfeng. This black domain is even more dangerous than the essential magical power of the Shadowless Gangfeng?

"You have been here for many years. Don't you know what is in the depths of the Black Domain?" Yang Kai asked with a frown.

Luan Baifeng shook her head: "If it weren't for you this time, I wouldn't have gone deep into such a place."

"It seems that there is something big secret hidden in this black domain!" Yang Kai sighed.

However, no matter how dangerous it is ahead, since you know that there is such a critical point, Yang Kai will naturally not easily step over the line. The secrets in the deep black domain will be higher in the future, and it will not be too late to investigate again.

"You can recover first. I'll find out if there is a suitable mine star. Maybe there will be a place to help you." Yang Kai greeted.

Luan Baifeng was not polite to him, and immediately took out the Kaitian Pill to swallow and refine it to make up for his own losses just now.

Although Yang Kai also suffered losses, his background was much more powerful than Luan Baifeng, and the loss of power did not prevent him from continuing to act.

Traveling around and constantly searching.

However, after searching, I couldn't find a suitable mineral star. It was either too big or too big to take it away, or it was too small and not worth taking it away.

Two days later, Luan Baifeng opened her eyes and looked rosy, and she had obviously recovered.

"What's the clue?" she asked at Yang Kai.

Although she had been meditating and recovering, she had not investigated everything about the outside world. She could detect Yang Kai's actions these two days, and she vaguely felt that Yang Kai seemed to have some plans.

"Come on, use your pupil technique to see what type of formation is here?" Yang Kai pointed to a problem in the void ahead. Under the eyes of the Demon Destroying World, he could see traces of a forbidden formation there, but because of his poor attainment in the formation, he could not judge the type of formation.

When Luan Baifeng heard this, she immediately urged her pupil technique, looked for a moment and said, "It should be a illusion array!"

"Illusion Formation!" Yang Kai frowned and took her to another place, pointing to the forbidden formation in front of him: "Where is this?"

Luan Baifeng observed for a while and said, "This is a trapping formation!"
