"OK, it's a deal. Second, I need to read all the stone carvings, virtual building beads and other materials of Arctic Tiancheng that I can read. Of course, if I find useful materials, I will sort them out and give them to Longcheng. It's my merit in the list of wizards."

"This is simple, Ben Sheng agrees." Ao cave nodded.

"As for the third, Arctic Tiancheng is the largest city outside the dragon city. There must be a lot of transactions in it. I hope to exchange my things for some stone carvings or treasures needed by our Terrans."

"It's nothing. You can change it at will." Ao Ku said.

"No, I have too many things. I need to hold a trade fair for me."

The stone face of Ao cave smiled and said, "it's not that Ben Sheng despises you. Even if all Ben Sheng's treasures are added together, they are not qualified to hold a fair."

Fang Yun said, "it's not that I despise you. If I take out all I have and hold a fair a day, it's more than enough to hold it for 30 days."

"You... Hum! Ben Sheng has authorized you to hold a trade fair in the grand exhibition hall in the west of the city. Twelve days later, you happen to have one day's free time. First give me a trade catalogue!" Ao Ku said.

"Just a moment."

Fang Yun began to sort out the treasures in his six silver bodies and heaven and earth shells. Finally, he made shennian stone carvings with the method of the dragon family and gave them to Ao cave.

Ao Grottoes used to look arrogant, but when God just touched the stone carvings, his eyes were wide open and surprised.

"You... Have you robbed the treasure house of our dragon family? Why are many of your things measured in tens of thousands?"

"Because there are many," Fang Yun said.

Ao cave looked at Fang Yun and said, "don't deal with those divine medicines that enhance the mind, dragon body and soul body. Bensheng will buy them all. You can make a price. There are also those whole divine medicines. No one dares to buy them except Longting!"

"Can you afford it?" Fang Yun's tone was full of doubt.

Ao cave was furious and said, "this saint can't afford it. Can't he buy it together with other dragon saints?"

"Oh, that's right. I'll only sell half of the above magic medicine at most, and I'll use the rest unless you give me better treasures, such as Tianyuan mother liquor. In addition, I can't sell the remaining half only to you. I have to attract other guests, and I want to keep 20 percent."

"Good!" Ao Ku said.

Fang Yun stretched out his hand and said, "first give me an empty sky and earth shell, and I'll pack the magic medicine that can be sold to you, and then you can go to your friend to evaluate. As long as it is completed within 12 days, the contents will be yours."

"Good!"

Ao Grottoes said, opening his mouth, a heaven and earth shell emitting a faint color light flew out.

Fang Yun took the heaven and earth shells, put them in the Ao cave, put away the heaven and earth shells, took out a stone carving, branded the list of items in the heaven and earth shells, and gave them to Ao cave.

"Don't you give me the shell of heaven and earth?" Ao cave was dissatisfied.

"Hand in money and hand in delivery," Fang Yun said.

"Hum!"

Ao cave took the stone carvings, finished reading them in an instant, nodded and said, "OK. You make a list of the items you want."

"It's better to be Taigu Qibao..."

Ao Grottoes immediately interrupted Fang Yun's words: "how do you mean to open your mouth? Although your things are precious, even if the number increases ten times, you can't exchange Taigu Qibao! There are only a few Taigu Qibao in Wanjie? Even the dragon's gate can't compare. Exchange!"

Fang Yun said, "I need Tianyuan mother liquor."

Ao cave stared at Fang Yun and said, "you are a great Confucian in the five realms. You need to forge your destiny as soon as possible. I can get many treasures to speed up the forging of your destiny."

"Sorry, I can finish forging my destiny in a month at most." Fang Yun said.

"Don't you boast that you can die? How old are you!" Ao Ku was angry.

"Let's make a bet? I'll be promoted to a literary giant in a month. You give me a semi holy treasure. No, I'll give you a spark huntianjian." Fang Yun said.

"You..."

The light in Ao cave's eyes is shining. The sky mirror is extremely precious. Not to mention changing a semi holy treasure, you can change a hundred. However, thinking about Fang Yun's list of treasures, he suddenly said, "you got great fortune in the doomsday palace?"

"Your Majesty Aoku is really smart." Fang Yun said.

"Hum! After you finish forging your destiny, you can fully control the power of your destiny. Next, you will forge the foundation of the holy way. You really need Tianyuan mother liquor. I can get some, but not much. What else do you need?" Ao Ku asked.

Fang Yun thought for a moment and said, "is there a Jiuji Tianzhu?"

Ao cave said angrily, "you are not old and have a big appetite! The Jiuji Tianzhu is an ancient treasure that supports the world. Didn't you hear what I said just now?"

"There are no fragments of Jiuji Tianzhu?" Fang Yun didn't care about Ao cave's anger at all.

"Er... It's true, but in the dragon city treasure house, don't talk about me. Dragon Dina has to consume a lot of military skills. But..."

"But what?"

"Your reward for the military Baron is uncertain. If you can take another two steps and get the fifth class military Baron, it seems that you can ask for the reward of the fragments of Jiuji Tianzhu." Ao cave said.

"I can be promoted to the first-class military Baron if I am the first in the list of killing emperors and the list of military achievements. Now I am the seventh class military baron. If I am the first in the two lists, is it equal to getting the fifth class military Baron?" Fang Yun said.

"Of course. No, why are you the first in the double list? You are the first in the double list and the first in the military Baron list is the first in the third list. Are you a waste when you are other emperors? I think you can change your name and change it into Fang boasting!" Ao Ku was very angry.

"If I can be the first in the three rankings, dare you bet with me?" Fang Yun asked, his tone full of contempt.

"Dare! What dare you!" Ao cave was finally stimulated.

"OK, it's a deal! If I'm the first in the three lists, I don't want your treasures, as long as you help me find some treasures I need, such as the source of heaven and earth." Fang Yun said.

Ao cave felt that he was going crazy and said angrily, "why don't you compete for the first place in the four lists? If you get the first place in the list of wizards, you also have a chance to ask the Dragon Court for the source of heaven and earth."

"I'm ready to trade the first place in the list of wizards for the holy fruit." Fang Yun said solemnly.

"Can you book all this? You're so angry with me. I... forget it. If you can really be the first in the four rankings and get a lot of military skills, plus your identity as Wenxing longjue, it's enough to change the source of heaven and earth. However, you can only change a small part... I see!"

Ao cave suddenly stared at Fang Yun and said slowly, "are you preparing for your literary world? The source of heaven and earth evolves the literary world, the mother liquor of Tianyuan expands the literary world, and the Jiuji Tianzhu strengthens the literary world. Coupled with the spring of sentient beings, it is simply to recreate the miniature 10000 world, which is more difficult than creating an ordinary world."

Fang Yun smiled and said, "Your Majesty Ao cave is really well-informed. Yes, I do lack a little source of heaven and earth. As for the spring of sentient beings, I don't have any. Is there any in the dragon city?"

"The spring of sentient beings has long disappeared, and it disappeared before the prosperity of the dragon family. The spring of sentient beings is one of the ancient treasures. It is said that the spring of sentient beings only exists in the imperial soil where the imperial family lives. There is indeed imperial soil in the falling star sea, but it is just the edge of the imperial soil. There can be no spring of sentient beings at all. Therefore, don't think about it. No one can create a perfect holy world, and the holy ancestors of all ethnic groups can't , Kong Sheng can't, neither can you! "

"Always try to know." Fang Yun said.
