But in fact, the moment Gong Yutian saw Bai Luotian, his eyes lit up, others may not know Bai Luotian, but he does, as he has been walking in that place all the year round, how can he not know him? What's more, the swordsmanship given to Xiao Jiu was still obtained from him.

Bai Luotian, the Tiangang Sword Venerable who once shocked the continent, didn't expect him to appear here.

When the old man of Yin Yang saw the man with crane hair and a childish face come out, he completely believed that all the momentum dissipated without a trace at once, and he might be able to fight to the death in the face of Youxi, but this Bai Luotian's strength was not at the same level as himself, and going against him was simply looking for death, not to mention that he knew a few years ago that this man was selected there, the palace that gathered the supreme powerhouses in the world.

That palace is a palace that even Cloud Tower City is afraid of, and now the supreme who is popular on the continent is a fart, and it is nothing in the eyes of those people, and in that place, the worst is much stronger than the so-called supreme who is now famous in the continent. Although the old man of Yin Yang was despicable and shameless, he knew the current affairs, and sure enough, under Bai Luotian's sight, he retreated directly.

"Hmph, the old man gave you face today, but it's no wonder the old man is out of here!" With a swish, the old man disappeared in place.

Outside the Treasure Pavilion, the old man of Yin and Yang stared at the door gloomily, "Whether it is a treasure map or a bone flower, it will be the old man's, unless you don't come out for the rest of your life." ”

Although Feng Rushuang has a good talent, he does not belong to that palace, nor does he belong to the people of Bai Luotian's era, so naturally he doesn't recognize Tiangang Sword Venerable, he just nodded kindly, when nothing happened: "Everyone, I just asked the seller, you can't use fire essence chalcedony instead, but the auctioneer has also relaxed the limit, the fire spirit root is hard to find in the world, so it is okay to exchange it for spirit stones, and the reserve price is ten low-grade spirit stones."

Spirit stones? Ten bucks?

Many people looked at each other, all suspicious, spirit stone? The so-called spirit stone is a kind of mineral, condensed by the aura of the essence of heaven and earth, one level higher than the spirit stone, the spirit stone contains the power, the spirit stone naturally contains the spirit power, the spirit stone and the spirit stone are the same, there are grades.

And the spirit stone is naturally from the ore vein, generally the spirit stone just dug has a protective layer wrapped, and the wrapping layer is pure broken spiritual power, the grade of the spirit stone comes from here, depending on the purity and concentration.

If it flows into the market as a trading object, it needs to be polished, which is similar to mining jadeite stones, etc., and the outer skin must be cut to know whether it is grass or treasure inside. Then it can be polished into a square shape of the same size, and you can enter the market. And the kind of spiritual energy crystal source stone that Yeyun has is a kind of spiritual stone energy, and the source, even if it has not been polished, is still full of spiritual energy.

Xuanling stones are rare, and spirit stones are even rarer, which directly makes everyone dumbfounded again!

Just when everyone thought that no one could get the spirit stone, a voice came from the fourth floor, "Fifty lower-grade spirit stones." ”

"Day~~~"

Everyone was startled by this sudden sound, and their hearts beat violently, revealing a shocked look, the spirit stone, actually fifty lower-grade spirit stones at once, this is estimated to be the highest price in the ** cave in history, the spirit stone is so rare, it is fifty at a time.
