A little bit of earthy yellow brilliance appeared in Ye Kong's fingers, and the rich earth qi surged, intertwined with each other, and penetrated into the 'fluorescent stone' in front of him.

"Is it a geo-qi detection technique, it's just a rural technique, and you dare to take it out to be embarrassing?" Fang Yiming's face was full of disdain.

Before Fang Yiming's words fell, he saw an illusory picture appear on the fluorescent stone, it was an ancient mountain, and there was a rough stone on the top of the mountain, which was bathing in the sun, it was this fluorescent stone.

"Tracing back to the source!!, how is this possible?" Fang Yiming exclaimed in surprise, his voice full of shock.

Everyone in the audience was shocked, and Jue Qianchen sighed with emotion: "Tracing back to the source, this is the legendary earth qi secret technique, I can't imagine that it really exists!"

Liu Xinfei's eyes flickered, and her voice flowed like a clear spring: "Hearing Ye Kong's performance in my Yunxia Stone Workshop, I knew that Ye Kong was absolutely extraordinary, and I was really not mistaken." ”

"Ye Kong actually has mastered the secret technique of 'tracing back to the source', it seems that he has a better chance of winning this time. "Everyone was originally biased towards Fang Yiming, but when they saw Ye Kong perform the secret technique of 'tracing back to the source', many people fell to Ye Kong.

"The first rough stone, I choose the 'fluorescent stone'! Please take care of it for the snow fairy!" Ye Kong decisively selected and sent the 'fluorescent stone' into the circle that Xue Ling'er drew for him.

Fang Yiming snorted coldly: "What about tracing back to the origin? Earth Qi Secret Technique, each has its own merits, some strange stones, even the old generation of Earth Qi masters who have practiced for hundreds of years can't see through it, even if you can see the origin of the original stone, you may not be able to cut out the treasure!"

"I can understand that you are jealous of me?" Ye Kong laughed harmlessly.

Fang Yiming snorted angrily and turned his head to look for other primordial stones.

Ye Kong came to the side of the stream and fished out a blue-gold rough stone from the water, and a row of information appeared on it: Qingdao Stone, weighing 900 catties, worth 9,000 catties of spiritual marrow.

"This is the 'Qingdao Stone', weighing 9,000 catties, which is a kind of rough stone with a high value in the best rough stone area, does Ye Kong want to choose this rough stone?"

"In the past, someone has investigated more than once with the secret technique of earth qi, and this 'blue path stone' can emit a mist sound, but it is too ethereal, and many older earth qi masters guess that there is nothing inside. Moreover, the price is too high, so it has been put on hold here. ”

"Ye Kong has mastered the secret technique of tracing back to the origin, and he may be able to see other visions. ”

Everyone was discussing excitedly, even more excited than Ye Kong.

A little bit of earthy yellow earth qi fluctuations appeared in Ye Kong's hands, and along the trajectory of the mystery, it penetrated into this 'Blue Dao Stone', and a floating heavenly sound suddenly came out from the 'Blue Dao Stone', as if it could purify people's souls.

If you listen carefully, you can't hear anything, and everything just now is as if it never happened.

"Sure enough, there is an ethereal heavenly sound! Can Ye Kong see more?" everyone's eyes were full of anticipation.

The secret technique of tracing back to the origin was used, and the vision of the original stone was once again manifested on the blue-gold rough stone.

It was an ancient platform, on which there was an unreadable figure preaching, and the big colorful characters flashed out of thin air, submerged into the surrounding platform, and disappeared like a mud cow entering the sea.

"This is actually the cornerstone of a Taoist platform! It may contain the method of the strong man's preaching!" many people exclaimed.

Ye Kong's brows furrowed slightly, even he was not completely sure about this rough stone.

"Master, choose this piece!" Suddenly, Shi Xin shouted loudly, his little face full of excitement.

Thinking of the origin of the stone heart, Ye Kong's heart moved slightly, raised his hand and sent the 'Qingdao Stone' volley into that circle, and said, "The second rough stone, I will choose this 'Qingdao Stone'!"

Seeing this scene, everyone was somewhat surprised.

"Ye Kong shouldn't be sure if there is a treasure in this rough stone, and after listening to that little ghost's words, he chose it directly, it's really child's play. ”

"What's the origin of that little ghost?"

"I don't know, according to some monks who have entered the Yunxia Stone Workshop, that little ghost should be Ye Kong's apprentice. ”

"Anyway, today we all have eyes, so many rough stones that no one dared to touch before, they dare to choose, today is really the right time!"

"Brush!"

Everyone was discussing with each other, and suddenly, a brilliant purple light came from afar, covering the entire area of the best rough stone with a layer of purple brilliance, the needles of the pine trees were full of purple light, the clear spring water was like a purple dream tassel, and everyone's body surface was covered with a layer of faint purple brilliance.

"Purple cedony! There must be purple chalcedony in that rough stone, and it's not ordinary purple chalcedony!" many people blurted out.

Fang Yiming laughed, sent a stone with a pitted surface into his own circle of rough stones, and laughed loudly: "The second rough stone selected by Fang Mou is this 'Ma Pit Stone'!"

Ye Kong and Fang Yiming each performed their own unique earth qi secret technique, quickly sensing the reactions of each primordial stone, and selecting the primordial stone that they thought was suitable.

The number of rough stones in this area of the best rough is limited, and whoever is fast will be able to take a part of the opportunity. If the speed is too slow, it will be too late until the other party chooses, even if you want to choose.

Soon, Ye Kong and Fang Yiming each selected five or six rough stones, some of which were imprinted with natural beast drawings on the surface, some of which had various visions, some contained surging dead qi, some were tumbling with fierce demonic qi, some were flying with colorful clouds, and some were rising with immortal qi, and each piece of rough stone was extraordinary.

The price of these rough stones is not lower than 5,000 catties of spiritual marrow, and ordinary people really dare not move.

At this time, Ye Kong and Fang Yiming both looked at the many rough stones in the best rough stone area, and felt that there was nothing else to start with, and their eyes were fixed on the cold stone hill.

This stone hill is not high, only tens of zhang high, and it is full of large and small rough stones.

These rough stones are all unique to the Ice God Stone Workshop, and they can't be seen anywhere else at all.

The rough stones on the stone hill are of different sizes, but each piece of rough stone is extremely heavy, the smallest one is more than 8,000 catties, and the rough stones on this stone hill are generally few people dare to move.

Seeing Ye Kong and Fang Yiming going up the mountain, everyone's emotions became even more excited.

"They are going to the Ice Cold Rough Stone Mountain, those rough stones contain an extremely strong cold aura, which has a great impact on the Earth Qi Secret Technique, dare to move these rough stones, they are really bold!"

"These rough stones are all mined by the Ice God Palace, and the cold breath in the rough stone is a great obstacle to the earth's qi, and the cold breath is very heavy, it is really not cost-effective to choose this kind. ”

"No, some of the cold rough stones do contain supreme treasures, and someone has cut out the black pith from them!"

"If the rough stone is not cut, no one can tell what is inside, so wait and see!"
