Just as she was about to continue digging, Yun Xinran sighed lightly, because she actually found a spirit stone the size of an adult's fist, and the light of this spirit stone was many times stronger than other spirit stones!

"This is? Medium-grade spirit stones? Yun happily pried the spirit stone from the ground, put it in his hand and looked at it, muttering with some uncertainty. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

The grade of the spirit stone is mainly judged from the purity of the spiritual power contained in the spirit stone, and the spiritual power of the medium-grade spirit stone is often more than one hundred low-grade spirit stones, and the impurities are many times less.

And this piece in Yun Xinran's hand is indeed a medium-grade spirit stone. Yun happily put away the spirit stone, and then continued to dig.

"That's too slow!" Yun happily wiped the sweat from his forehead and muttered secretly.

After thinking about it, Yun Xinran suddenly had a flash of inspiration, and his divine soul entered the Pangu Jade space and found Xiao Hei.

"Master, are you in trouble?" Xiao Hei tilted his cute little head, and two small fangs were faintly exposed when he spoke.

"Well, that...... Is there any good way to quickly mine this entire vein of spirit stone? Yun Xinran hesitated for a moment, but still said it, her divine thoughts had actually penetrated into the earth spirit stone under her feet, and found that there was a distance of thousands of miles below, except for the rocks, almost all of them were spirit stones, and some of them even reached the upper middle grade. I'm afraid it will be delayed for several months, and it would be a pity if I left.

She could record this landmark into her Boundary Breaking Stone, but she didn't dare to guarantee that she would return here in half a month, and there would still be a large number of spirit stones waiting for her now. The Great Array of the Xuanling Secret Realm had been broken, and she didn't dare to guarantee that people outside wouldn't find here. Especially those who are strong in the Heavenly Spirit Mirror, their abilities are even more unpredictable than she can guess.

Yun Xinran was right, when almost all the disciples left the Xuanling Secret Realm, there was no formation suppression, and those sect elder-level figures entered this place and searched for it.

It's just that the place where Yun Xinran is located is within the abyss of the core area, but those people haven't found it here yet, although these places have all kinds of natural obstacles, but those Heavenly Spirit Realm elders

still came to the dense spatial crack in the core area......

In the Pangu Jade space, the corners of Xiao Hei's mouth raised: "Master, what's so difficult about this?" ”

Yun Xinran's eyes lit up: "Do you have a way?" ”

Xiao Hei raised his small chin, and his big eyes narrowed proudly: "I am the spirit of an artifact, and I have a certain combat power in my own right!" ”

"Uh, so what's your solution?" Yun Xinran muttered to herself, she didn't ask Xiao Hei if he had combat power! However, Xiao Hei's answer really made her eyes light up.

Xiao Hei smiled and said nothing, Yun Xinran had no choice but to look forward to it.

The spirit returned to the body, and when Yun Xinran opened his eyes, his white palm was raised indifferently, and a child dressed in black appeared in her palm, which was the pocket version of Xiao Hei!

Xiao Hei glanced at the spirit under his feet with disdain, but his little hand was shining with black light and pointed at the ground!

A black light shot out from Xiao Hei's short fingertips, but when it landed, it turned into a black four-legged lizard!

"What is this, lizard?" Yun Xinran hadn't finished asking yet, and then in Yun Xinran's surprised gaze, the lizard actually moved its limbs like hot wheels, and its figure was even more afterimaged, but in a moment, dozens of spirit stones were piled up on Yun Xinran's side, and this speed was simply dozens of times that of Yun Xinran!

"This is just a low-level demon transformed by demonic energy, but it is enough to dig spirit stones." Xiao Hei looked lonely.

In just a few breaths, hundreds of spirit stones were piled up under Yun Xinran's feet, and there were even two medium-grade spirit stones, which was quite amazing, but it would take a month or two to hollow out the entire ore vein.

When Yun Xinran thought like this in his heart, thousands of spirit stones had already piled up under his feet again, and a mountain of earth had also piled up in front of him, and the corresponding pit under his feet was even bigger, except for the place where he had a foothold, all the places had been hollowed out! Yun Xinran was embarrassed, such a short time was actually comparable to her results in two or three days.

Xiao Hei seemed to see that Yun Xinran was not too satisfied with the current speed, he pointed a little again, and another lizard of the same kind appeared, this time the speed of digging doubled, and then, Xiao Hei clicked dozens of times in a row, and suddenly the number of black lizards also increased by dozens! Under Yun Xinran's dumbfoundedness, a gust of wind broke out in the entire spirit stone pit, and dust flew all over the sky!

Yun Xinran hurriedly raised her protective light shield and wrapped her whole body, and her subordinates couldn't help but start collecting the spirit stones, and her heart was full of joy!

But another half a day passed, and the number of spirit stones in Yun Xinran's storage ring increased to 30,000!

Another half a day passed, Yun Xinran's storage ring was already full, and she stuffed all the spirit stones into her Pangu jade space, but something unexpected happened to her!

The entire Pangu Jade space suddenly shook, and Yun Xinran actually found that the 30,000 spirit stones he had put in had melted away like ice cubes, and they had been replaced by ......

The entire Pangu Jade space seems to have become a little wider, one thousandth more space than before!

"This!" Yun Xinran was shocked, the spirit stone could actually expand the space of Pangu Jade!

Yun Xinran almost forgot about the distressed spirit stones at this moment, and felt that thousands of spirit stones were piled up under his feet, and Yun Xinran put the thousands of spirit stones into the Pangu Jade space again, but this time the same thing happened, but the amplitude of this vibration was very small, and the widened place was only a few squares, but Yun Xinran felt everything clearly under the serious sense!

"Although there are not many spirit stones here, this is so-so, master!" Xiao Hei also seemed to feel the changes in the space of Pangu Jade, and said lightly.

"Hey, it's a pity that there are so many spirit stones." Yun Xinran calmed down the shock, but he felt distressed about the spirit stone.

"Master, what is this spirit stone, as long as the master can successfully cultivate this small world in the future, it will become your most powerful backing, you don't have to worry about the problem of spiritual power depletion during the battle, as long as there is this small world, you will have a strong backing!" Xiao Hei looked at Yun Xinran with a very illiterate expression.

Yun Xinran couldn't help but touch her chin, feeling that this look was really familiar. Suddenly reacted to what Xiao Hei just said, and his heart couldn't help beating: "What... What the? You're saying that I can directly extract the power in the Pangu Jade space? (To be continued.) )
