The stone slab fell freely about three zhang into a dome hall with a diameter of three zhang, and the four people landed from the very top of the dome. The ground of the hall and the surrounding areas are also engraved with complex patterns, and the Chiyan Patriarch pointed to a desk in the center of the hall and said: "After Gongzi Chu has finished cultivating, return here and directly input mana on the jade in the center of the desk to open the stone slab above, if there is any accident, with the strength of Gongzi Chu, he can also break through anywhere in the passage and return to the ground." ”

Patriarch Chiyan This is to reassure Chu Zheng, and Chu Zheng nodded to show that it is clear. In fact, with his formation attainments, he had already seen that the formation in the hall was simply absorbing the power of the earth fire and the poison of the earth fire that had spread.

Under the leadership of the Chiyan Patriarch, the four of them walked into the only passage.

The passage is inclined to extend downward, one zhang wide, the top is arc-shaped, and the highest point is about three or four zhang, and around the passage are inlaid with pieces of spirit stones that have exhausted their spiritual energy, but these spirit stones are no longer pale white, but contain the scorching power of light red.

"These spirit stones will form red flame crystals in another hundred years, right?" Chu Zheng glanced at it, and was a little surprised in his heart.

"To be exact, it will take ninety-five to one hundred and three years to become a low-grade Red Flame Crystal, and the last year of that will be immersed in earth fire. ”

The formation of the Red Flame Crystal is the fire power of the earth's lungs that impregnate the spirit stone ore, and finally completely contain it. This process is very long, and even the formation of low-grade red flame crystals takes a hundred years. These blank spirit stones have obviously been inlaid here for an unknown number of years.

Walking down the passage for a thousand zhang is like this, some will become a red flame crystal in a few years, and some will take hundreds of years. Chu Zheng couldn't figure out how many there were for a while, but the amount of Chiyan Crystals produced every year was probably a shocking number, and a low-grade Chiyan Crystal could be exchanged for ten spirit stones. This is a huge fortune, this is the heritage of the Chiyan family!

After a thousand zhang is a dome hall with a diameter of ten zhang, there are ten stone houses on both sides of the hall, and the Chiyan patriarch introduced: "It is difficult for ordinary people to survive here, and these stone houses are used by the cultivation of the younger generations at home. ”

Chu Zheng praised from the bottom of his heart: "The ancestor of the Chiyan family is really majestic. Sealing the earth fire vent so that the fire of the earth lungs cannot be vented, and special spiritual materials and spiritual plants are planted on the mountain walls around the vent, and red flame crystals are formed in the passage, which can be used by the children of the family to cultivate. This is no longer a thousand-year plan that can be described, and the existence of the Chiyan family here can be said to have lasted forever. Chu admires!"

The Chiyan patriarch was obviously scratched by Chu Zheng, and laughed: "Brother said that it was funny, it is just the dream of my Chiyan family to survive forever, and everything still has to be based on strength." ”

Passing through the hall is still a passage, and the passage is still inlaid with blank spirit stones. Walking out of a thousand zhang is still a hall, or ten rooms, the Chiyan Patriarch introduced: "This is the place where my family's foundation building stage disciples cultivate. ”

Glancing at the three of them, he continued to move forward, and a thousand zhang behind him was the place where the disciples of Jin Dan cultivated.

The Chiyan Patriarch glanced at the three of them again, and it was difficult for ordinary Foundation Building Innate Cultivators to survive here, so he had to be cautious. Fortunately, Chu Zheng and the old man in the soap robe looked as usual, and only Song Zesheng, who was born and cultivated from the heart, was the same, but the robe of the rich and noble son, who was not visible, had a faint streamer on it, as if he was absorbing the qi of earth fire. Seeing this, the Chiyan Patriarch was relieved to lead the three of them to continue to move forward.

Another thousand feet away, turning a corner, has reached the end of the passage. As soon as he stepped out of the passage, the robe on Chu Zheng's body spontaneously ignited without fire, and instantly turned into ashes.

Chu Zheng's mana shook out the flames, and he casually put on the Qingxuan battle robe.

It is a huge underground cavern, and in front of several people is a semi-artificial and semi-natural magma pool. The magma pool is ten zhang in diameter, and the center of the pool is a round platform with a diameter of four feet.

"This is the place where my family's Jin Dan was promoted to Yuanying or the early stage of Yuanying's cultivation, and it is also the place where the Chiyan Crystal is stored. Rely on the Red Flame Crystal to increase the absorption power of quality and reduce the power of earth fire. ”

The Red Flame Patriarch stretched out his hand and grabbed it, and a fiery red palm sank into the magma, and when he returned again, the fiery red palm dissipated, and a piece of red red flame crystal fell into the palm of his hand.

"Song Gongzi take a look at the quality of this piece of red flame crystal?"

Song Zesheng carefully looked at it for a long time, and said: "The best of the best, the Qingxuan Continent can be sold for a thousand spirit stones. It's just that I don't know how many of these Chiyan crystals there are in the Chiyan family. ”

"Song Gongzi is honest, and he doesn't hide it. After all, the melody world is too small, and the amount of Chi Yan Crystal, especially the best Chi Yan Crystal, is very small, and my family does not dare to sell it on a large scale, putting the family in a dangerous situation. This grade of Red Flame Crystal was secretly sold for a small amount at a price of only six hundred spirit stones. As for the quantity, Song Gongzi can rest assured that my family can provide 200,000 pieces of Chiyanjing of this quality at one time, and as long as the trade route is stable, it can also supply 100,000 pieces per year. ”

Although the Qingxuan Continent can sell at a higher price, the transmission cost is high, and it is impossible to carry a large box over, which requires a storage bag, and even if the storage bag is small, it is not much to make a profit, so it is better to sell it in bulk in the melody world. You can only earn more if you carry a lot of goods at a time.

"I have all the three hundred pieces, and I can also buy them for a long time, door-to-door purchases. ”

"Three hundred is a little lower. ”

"It's not low, it's not a secret, as long as the spiritual materials that can be artificially cultivated, the price is not high. The real big families have such a place, and now I have a land of earth and fire cultivated by Chiyan Crystal under my name, but it doesn't take long and produce much. ”

The two bargained for a moment and reached an agreement, Song Zesheng was responsible for the door-to-door purchase, only buying the best Chiyan Crystal, and the purchase price was a piece of three hundred and thirty spirit stones.

The Chiyan family has 66 million in income this time, and there are 33 million in income every year, and the expenses of this big family can not only ensure that there is still a lot of surplus. Moreover, this is not all the output of the Chiyan family, including other outputs, Chu Zheng believes that it is less than half of the family.

The process of the two reaching a deal also gave Chu Zheng a lot of insight. Compared to the Chiyan Family, the so-called Four Great Gate Valves and the Imperial Family in the Heavenly Source World are simply weak. They are still emptying the resources in their territory, but the Chiyan family has begun to form a long-term virtuous cycle of development, and even the income of this alone exceeds that of any gate valve. The root cause of such a huge gap is the foresight of the ancestors of the Chiyan family.

"Little friend, see if this place meets the cultivation requirements? If not, let's continue to go deeper. After talking about the deal, the Chiyan Patriarch looked at Chu Zheng.

"The place is okay, but this place is really not suitable for cultivation. And I don't need the platform in the Earth Fire Pool, I need to stand on the Earth Fire for my cultivation. "The pool is full of top-grade red flame crystals, and it is not clear if there is one less piece.

Chu Zheng didn't feel anything when he said this, but including the Chiyan Patriarch and Song Zesheng, and even the old man in the soap robe glanced at Chu Zheng in surprise. Standing directly on the earth fire to cultivate? What a strong physique is required for this.

The soap-robed old man stared at Chu Zheng and looked at him carefully, and said, "Zesheng, after you go out, you will immediately collect more Yuanji Magnets, I'm afraid a small piece will not be enough." ”

Chu Zheng looked at the old man with a shocked expression, obviously the old man had grasped the core needs of his cultivation of the Tianyuan Bafang.

"Definitely. The stronger my brother-in-law is, the safer I am. I buy everything I have in the melody world, and I take it from home if I don't have it. In order to escape from his sister's clutches, Xiao Zesheng also fought hard.

Chu Zheng shook his head with a smile and said, "After I finish my cultivation, I will ask the seniors to help the juniors refer to the exercises." ”

This is equivalent to giving "Tianyuan Bafang" to the Song family, although the Song family cannot sell it, but the value is definitely far beyond the Yuan Ji Magnet consumed. But sometimes not everything has to be valued, not to mention the friendship generated by this period of contact and understanding, that is, when Chu Zheng fought the immortal body outside Lintian City, he got the help of Yuanji Magnetic Mother at the critical moment to cultivate for great progress, and this kind of favor is not measured by value.

"No, no, no. ”

Song Ze said proudly: "There are very few places where the Yuanji Magnetic Mother is used, and it is useless in the hands of people who don't use it." I'm a big businessman, and what I do is buy useless things from people and sell them at a high price to a useful person. So these things are cheap to me, and besides, my brother-in-law you use them, and I can make a deal?"

The words were heroic, but the cunning in his eyes was clearly seen by Chu Zheng. This clearly means that if you want to make a deal, you can't do it, and my sister is counting on you to carry it for me. What kind of natural quality is not natural exercises, it is not at all more important than completely escaping from my sister's hands.

Chu Zheng was speechless. It seems that this thing can't run if you want to.

A few people continued to walk towards another magma pool, and the Chiyan Patriarch said, "Little friend, you can destroy the central platform, and when the time comes, someone will use us to build it again, and it won't cost much." ”

Chu Zheng nodded, took off the storage bag and was about to hand it to Song Zesheng, but the Chiyan patriarch stopped him and said, "Xiaoyou doesn't have to be like this. Although my Chiyan family is relatively independent, it also has its own principles for doing things. Since you have good intentions and kindness to my Chiyan family, what if you take away the Chiyan crystal? My Chiyan family will not say a word more. Besides, Xiaoyou will definitely need some items in the storage bag for cultivation, and it will definitely be inconvenient without the storage bag. ”

When Chu Zheng heard this, he took back the storage bag.

The Chiyan patriarch explained a few more words, saying that he would arrange individuals in the retreat place of the Jindan period, and Chu Zheng would supply all the Chiyan family with any needs, and the Chiyan family did not have much else, but there were many spiritual materials and spiritual plants involving earth fire.

When the three of them left, Chu Zheng took off his combat boots and flew onto the platform in the magma pool.

With a strong step on his right foot, the hard platform immediately collapsed and sank into the magma pool. At the same time, Chu Zheng threw the Yuanji Magnet Mother into the magma pool in his hand, and cast "Tianyuan Bafang" to slowly sink until the soles of his feet completely stepped on the magma.
