Lin Yun came to the hall outside, bought a few ordinary gambling stones, and also bought a stone solving knife for calcing, a book on calcing, and prepared to practice after going back, Lin Yun didn't know anything about calcing.

In this way, Lin Yun's return to Qingyun Sect was delayed. But there is nothing to do, and no one cares about the inner disciples who have been in retreat and going out to practice for a long time.

Lin Yun did not live in the city, but entered the space of the Great Dao Stone Pan in a remote corner of the city, where the stone would not be affected.

Lin Yunpan sat in the space of the Great Avenue Stone Plate, except for the small ball ball, that is, Bai Lao.

Lin Yun teased the little ball for a while, gave it a spirit fruit, and let it play aside, while he took out the book and read it carefully.

Since opening the hidden vein, Lin Yun's brain has been nourished by the aura and has become extremely intelligent, and it only took two hours to read the entire book and master it all.

Lin Yun put the book away, closed his eyes and calmed his brain, then took out a stone dissolving knife, took out another gambling stone, and began to slowly dissolve the stone according to the introduction in the book.

"Conform to the texture of the stone, lightly cut the knife, perceive the situation inside the gambling stone, untie a layer, and then knot a layer, do not rush it, and do not reverse the pattern."

While learning the contents of the book, Lin Yun used the knife in his hand to untie the gambling stone in his hand.

However, Lin Yun soon realized what it meant to be on paper, and when he learned that he had to do it, he soon broke the gambling stone in Lin Yun's hand into several pieces and fell to the ground, and one of the spirit stones inside was also broken.

Lin Yun didn't think it could, after all, calcing stone can't be done overnight, Lin Yun adjusted his mood, took out a gambling stone again, and began to dissolve the stone.

Three days later, Lin Yun sat on a pile of rubble, the knife in his hand carefully unraveling the fist-sized stone in his hand.

Clang!

With a crisp sound, the stone-solving knife in Lin Yun's hand stopped, and immediately changed and found that it had changed from vertical to horizontal, and a piece of stone skin fell off, revealing the contents inside.

"It's the Water Spirit Stone again."

The corners of Lin Yun's mouth twitched, but the movements in his hands did not stop, and he quickly unraveled the water spirit stone and threw it to the small ball that was waiting on the side.

Looking at the small ball that was clattering the spirit stone and swallowing the spirit stone on the side, Lin Yun showed a smile.

"Almost, it's time to untie those two stones."

In the past three days, Lin Yun has been unraveling the stones endlessly, so he had to go out a few times, and went to the rest of the gambling stone shops to buy some gambling stones for practice, of course, all the things that were solved went into the stomach of the small ball.

And Lin Yun's calcing skills are becoming more and more proficient, and now Lin Yun feels that he can unlock the two gambling stones he bought.

Lin Yun did not go to the stone plate immediately, but left the Great Dao Stone Pan, found an inn, had a good meal, and then slept again, adjusted his state to the best, and then entered the Great Avenue Stone Pan.

Lin Yun first took out the egg-like stone and put it on the open ground, looking at the huge gambling stone in a square circle, Lin Yun was also a little stressed, the spirit stone is not important, I am afraid that the things inside are too precious, and if I break it, then I want to cry without tears, but it can be solved outside, but what if the things inside attract some people and slap my own life.

Lin Yun calmed down, held the knife in his hand, and began to carefully dissolve the stone.

As the layers of stone skin turned into stone powder and fell to the ground, the volume of the entire stone began to shrink, when the gambling stone was only the size of a human head, Lin Yun replaced it with a smaller knife and began to unravel it slowly.

An hour later, the gambling stone in Lin Yun's hand was only the size of a ping pong ball, and at this time, Lin Yun began to wonder if there was nothing in it at all.

Jingling!

Just as Lin Yun cut the last knife, a crisp sound came out.

Lin Yun also breathed a sigh of relief, it seemed that there was indeed something inside.

After determining the size and location, Lin Yun quickly unraveled the contents inside.

"What is this?"

Lin Yun looked at a stone ball the size of a ping-pong ball on the table and said suspiciously.

Lin Yun took the small stone ball, it was heavy, and there was nothing surprising about it, which made Lin Yun a little suspicious that he hadn't finished solving the gambling stone.

"Boy, that's a good thing."

Just when Lin Yun was puzzled, Bai Lao appeared in front of Lin Yun, stared at the small stone ball in Lin Yun's hand and said.

"Bai Lao, do you know this thing?"

Lin Yun asked.

"Yes, this is a stone gall."

"Stone gall?"

Lin Yun was still very puzzled.

"I told you the reason for the birth of the Stone King."

Lin Yun nodded, Bai Lao did tell him.

"But there are some stones that are not able to form living beings because of lack of chance, and at this time, the essence of their bodies will continue to gather inside them, and eventually form all kinds of things. And these formed things, the corresponding effects are also different, for example, some form a stone core, which corresponds to the human heart, and stone blood, which corresponds to the human blood, but this stone gallbladder corresponds to the most special. ”

"What's so special?"

"It corresponds to the human eye, and for those who have cultivated the Pupil Technique, this is simply a priceless treasure, which can make the Pupil Technique reach the state of Great Perfection."

Bai Lao's words exploded directly in Lin Yun's ears.

This stone gall is simply too timely for him, the Heavenly Eye that Lin Yun has cultivated has not made any progress since Xiao Cheng, and now the opportunity is right in front of him.

"Bai Lao, is this stone gall really okay?"

"Yes, the harsh conditions for the formation of stone gall are only second to the formation of the stone king, but it is a combination of the innate sun essence and the innate moon essence, which just corresponds to the human eyes."

"And how should I use it?"

Lin Yun was already a little impatient at this time.

"It's simple, just pierce the stone skin wrapped on the outside and drip the stone gall essence inside into your eyes."

After Lin Yun heard this, he turned his sword intent and condensed it into a needle, piercing the outer skin of the stone gall, and in an instant, a stream of water that exuded a soft light flowed out.

Lin Yun quickly used his soul power to control the essence of the stone gall that flowed out, floating in the air, Lin Yun took a look, the essence of the stone gall condensed was a faint yellow as soft as moonlight, but it was indeed fiery red inside, as fierce as the sun.

Lin Yun counted it, and it didn't add up to ten drops.

"Boy, don't look at it, let's absorb it quickly."

Bai Lao's voice sounded in Lin Yun's ears.

Lin Yun nodded, controlling the stone gall essence into two parts, and slowly submerged into his left and right eyes.
