"Er, you are a great dragon family, and you can see the ordinary goods here?"

Hearing what long Aotian said, Cheng Feng joked.

"Cheng Feng, don't be weird."

Long Aotian said angrily, "I'll ask you if you can exchange it for me!"

"It's not impossible to exchange some for you."

Cheng Feng said, "however, you don't want the lion to open his mouth. I only have tens of billions of military skills left. I can't exchange anything too expensive."

"In addition, it's time to pay back the half kilogram of Tianlong blood you owe me?"

"You're strong now. It shouldn't be a problem to put half a kilo of blood out at will."

"Fuck you."

Long Aotian's face was black and said, "try half a kilo of blood yourself to see if there will be a problem?"

"Long Aotian, you owe me half a kilo of dragon blood."

Cheng Feng threatened, "do you want to default?"

"Who wants to default?"

Long Aotian's neck tilted back: "you exchange my baby first. When the exchange is over, I'll find a time to give you half a day's dragon blood."

"That's about the same."

Cheng Feng said with a satisfied smile, "OK, tell me, what baby do you want to exchange?"

"I'm recovering now, so please help me exchange tens of thousands of Jin of dragon yuan."

Long Aotian said with a big grin: "with this batch of dragon yuan, it must be able to recover Ben Shao's injury a little."

"What? Tens of thousands of Jin Long Yuan?"

The smile on Cheng Feng's face froze: "you ya Dang Long Yuan is Chinese cabbage. Tens of thousands of Jin Long Yuan is not worth a tenth even if you buy it."

"Tens of thousands of catties are not available, but thousands of catties are OK." long Aotian gave way.

"A few kilos? I think a few kilos are about the same."

Cheng Feng's face turned black.

Long yuan is not the ordinary commodity, but the essence of the dragon's life.

Moreover, if you want to condense the Dragon yuan, you must be a dragon family above the level of Dalong.

The dragon family below the big dragon can't call the dragon Yuan at all, and the effect is extremely poor.

For example, in Shilipo, long Aotian blackmailed a small half of the Dragon yuan of the two turtle dragons, which did little harm to it.

However, the Dragon yuan in the Royal treasure house must be high-quality products. It is estimated that one kilogram is more than 100 million military achievements.

Long Aotian needs tens of thousands of Jin to open his mouth. He's a pit father!

"Cheng Feng, how many kilograms of dragon yuan do you mean to say?"

Long Aotian had a thick skin and said angrily, "at least you have to exchange 1000 Jin of dragon Yuan for me."

"Otherwise, Ben Shao will stay here."

"Shit, are you cheating?"

Cheng Feng's mouth twitched: "what's your dignity of Tianlong family?"

"Ben, I don't care. If you don't exchange a thousand jin of dragon Yuan for me, I won't go. You can do it yourself."

Seeing the cheeky look of long Aotian, Cheng Feng is covered with black lines.

"Sample, wait for me."

Finally, Cheng Feng 'gave in' and threatened, "when you get out of the Royal treasure house, I won't cure your naughty problem."

When the voice dropped, Cheng Feng looked at Huang Kun.

"Old Huang, do you know if there is any dragon yuan in the treasure house? I want to exchange some."

"Long Yuan? Of course."

Huang Laodao said: "however, Longyuan is divided into several levels, including miscellaneous Longyuan, dalongyuan, wanglongyuan, shenglongyuan, tianlongyuan... And so on."

"The effect and price are different. Do you want to exchange that level of dragon Yuan?"

"Huang Lao, what are the prices of these levels of Longyuan?"

"Miscellaneous dragon yuan, usually one million military skills per kilogram."

Huang Lao said: "big dragon yuan, 100 million military skills per kilogram; Wang Longyuan, 1 billion military skills per kilogram; Holy dragon yuan, 5 billion military skills per kilogram..."

"I wipe, so expensive?"

After listening to Huang Lao's introduction, long Aotian was a little surprised: "Cheng Feng, how many military skills do you have left?"

"No detailed calculation, about tens of billions."

"Tens of billions of military achievements, which is too little, can only be exchanged for a few kilograms of Shenglong yuan."

Long Ao Tian Tucao: "if it is exchanged for dragon and dragon, it is estimated that half a catty can not be exchanged, and it is not enough to make complaints about the teeth."

"Long Aotian, what do you think?"

Cheng Feng said with a black face, "do you still want me to exchange 1000 Jin of Tianlong yuan for you?"

"If it's Tianlong yuan, you can exchange it for a kilo or two."

"Get out!" Cheng Feng scolded.

Then he looked at Huang Kun: "old Huang, I don't know if I can exchange some fire treasure materials for dragon Yuan?"

"I have harvested a lot of fire treasure materials in the inner earth world, which can't be used up at all."

"Yes, but I don't want ordinary things here."

"Don't worry, what I take out is definitely good things."

Then Cheng Feng took out some soul rings and handed them to Huang Laoguan.

"Fire crystal stone, earth hot fire crystal, fire essence tree..."

When Huang Lao took the soul ring, he didn't pay much attention to it.

But when he urged his mind, he glanced at the things in the soul ring.

All of a sudden, his eyes stared straight.

"Cheng Feng, did you bring these things out of the inner earth?"

"Good."

Cheng Feng nodded: "excuse me, old Huang, are these things eligible to be deposited in the Royal treasure house?"

"Qualified, too qualified."

Old Huang nodded again and again, quite happy.

"What's the price?"

"In terms of price, I'll give you an estimate."

Huang Lao said, and his mind shrouded the soul rings.

A few seconds later, his eyes lit up and said, "Cheng Feng, these fire attribute treasure materials, I'll give you an integer, just one trillion military skills!"

"One trillion military achievements?"

Hearing this, long Aotian's eyes almost stared out.

As for Cheng Feng, although he was prepared, he couldn't help raising his eyebrows.

"In addition, Cheng Feng, if you have other fire attribute treasure materials, you can also take them out together. I'll give you the highest price."

Old Huang looked at Cheng Feng with hot eyes.

"Old Huang, there are so many fire attribute treasures in my hand."

Cheng Feng said with a smile, "after all, the situation was critical at that time. I didn't have much time to collect."

In fact, Cheng Feng didn't tell the truth.

In him, there are many fire attribute treasure materials, and everything is fine.

For example, Cheng Feng left at least 100000 pieces of pyrolite.

The earth is hot and hot. Almost all those bigger than their fists remain in their hands.

Because these two things are good things to protect life.

Once more than 100000 pieces of pyrolite detonate in an instant, the strong people who climb to the sky will be embarrassed, seriously injured and disabled!

As for the earth fire crystal, its power is more terrible, enough to threaten the sixth most peerless figure in the sky!

"Cheng Feng, you can be called a rich man."

Old Huang didn't ask the bottom of the matter. When he heard Cheng Feng's words, he just smiled with regret.

"I'm afraid I'm richer than the head of a first-class family," he said with a smile

"Tell me, do you want to exchange that level of dragon Yuan?"

"Huang Lao, why don't you exchange these military skills into Tianlong yuan for me!"

Cheng Feng pondered a little and then said.
