Chen Fu and Ran Yun came to a stall on the west side of the first floor.

I saw that the bluestone platform was placed with some medicinal herbs, wood, stones, metal, and even an unknown liquid contained in a crystal bottle.

There are three kinds of medicinal materials that Chen Fu needs: muscle-building grass, strong bone grass, and golden lingzhi.

Chen Fu had already seen the exchange conditions just now, each medicinal herb had to be exchanged for a Blood Spirit Grass.

This Blood Spirit Grass is the main material for refining the Accumulation Pill, it is not a rare medicinal material, Chen Fu used to occasionally encounter it when he was collecting medicine in the Biyi Mountains, but now he does not have the Blood Spirit Grass on his body.

There were already a few people standing in front of the stall, their eyes sweeping around the bluestone platform, obviously interested in these things.

The stall owner is an old man in his fifties, wearing a robe with a round neck and large sleeves, and his face is indifferent. His eyes were slightly closed, and he occasionally lifted his eyelids to glance at the patron in front of the stall.

Chen Fu stood in front of the stall, leaned forward slightly, and shouted, "Stallholder." ”

When the old man raised his head, Chen Fu tapped the three medicinal materials with his fingers: "Stallholder, I don't have blood spirit grass on me, can these three medicinal materials be exchanged for yuan stones?"

"No, I don't change. "The old man is very simple.

"Blood Spirit Grass is not difficult to find, can't you take the Yuan Stone and go to the medicine picker or medicinal herb firm to buy it?" Chen Fu persuaded him bitterly.

"That's right, old man, I just like bartering. The old man said coldly.

Chen Fu was stunned, this old man is really different!

He straightened up and turned his head to look at Ran Yun, and sighed helplessly: "Miss Ran, let's go to other stalls and have a look." ”

These three medicinal materials are not rare things, they can also be purchased from other channels, and Chen Fu does not have to exchange them from the old man.

It's just that he wanted to refine the Birth Muscle Pill and the Bone Strengthening Pill as soon as possible to make a breakthrough, so he was a little anxious just now.

The two walked a few steps, some distance away from the old man's stall, Ran Yun asked Chen Fu in a low voice: "Xiao Langzhong, tell me, how much are these things worth?"

Chen Fu used to collect herbs for a living, and he was quite familiar with the prices of these medicinal materials, so he replied: "The muscles and bones are worth two thousand yuan each, and the golden lingzhi is only five thousand yuan each. ”

"Oh, it's only 5,000 yuan, so let's go ask again. ”

She pulled Chen Fu back to the old man's stall, took out a thumb-sized piece of metal from the prime minister's bag, stretched it out in front of the old man's eyes and shook it, and asked with a smile: "Stallholder, if I exchange this thing with you, are you willing?"

The old man stared at the metal block, his eyes shining: "This is ...... Fire Copper Essence, willingly! willingly!"

Fire copper essence is the best material for refining, just such a thumb-sized piece of fire copper essence, worth at least ten taels of low-grade yuan stones, equivalent to 10,000 yuan coins.

And the old man's three medicinal materials were worth only 5,000 yuan, of course he was willing!

"Then stall owner, do you think that my piece of fire copper essence can be exchanged with you for two muscle-growing grasses, two bone-strengthening grasses, and two golden lingzhi?" Ran Yun asked slyly.

The old man was stunned!

Ran Yun asked him for the first time if he was willing to exchange, but did not specify the amount of exchange.

The old man had a preconceived idea, thinking that Ran Yun was going to use this piece of fire copper essence to exchange with him for a muscle-growing grass, a bone-strengthening grass, and a golden lingzhi in the stall, so he was full of joy.

Ran Yun asked for the second time and asked the number of exchanges.

The old man realized that the little girl's first question was just a test, not that she didn't understand the market. I didn't notice it for a while, and I fell on the road and exposed my will.

With a grin, the old man smiled bitterly: "I only have one muscle-growing grass, one bone-strengthening grass, and one golden lingzhi." Why don't you see what else you need?"

"I don't need anything else, I just need these three herbs. Otherwise, what do you think of this piece of fire copper essence for your three medicinal materials plus five taels of low-grade yuan stones?"

“......”

The old man was speechless.

It seems that this little girl is a stall owner, but she has become a customer.

"Five taels is too much, a little less. The old man's tone was quite helpless.

"That's four or two. ”

"Deal. ”

The old man took out the four tael stones, put them together with the three medicinal herbs, and said weakly: "These belong to you." ”

Ran Yun put the fire copper essence on the stall, pulled the medicinal materials and the yuan stone together, and motioned for Chen Fu to put the medicinal materials away.

Chen Fu was still a little stunned at this time, thinking that this drama was turning too fast.

One picked up the medicinal herbs, the other picked up the yuanshi, and left the old man's stall with a smile and walked towards another stall to the east.

The stall on the east side was lined with stasis grass, snow lotus, and silver chalcedony, and the owner was a young man in his twenties.

This person is good at talking, and when Chen Fu offered to exchange yuan stones, he was full of promises.

In the end, Chen Fu and Ran Yun took three taels of low-grade Yuan Stones, exchanged them for two stasis dissolving grasses, a white snow lotus and two silver chalcedony flowers, and finally gathered the materials for refining a muscle-building pill and a bone-strengthening pill.

At this time, it was past Haizheng, and the people in the Treasure Hunting Pavilion seemed to be a little sparse, and most of them had dispersed.

Chen Fu thought that it might not be too late to visit the third floor again, so it was better to come back another day when he was free. After consulting Ran Yun's opinion, the two left the Treasure Hunting Pavilion together.

Out of the gate, Chen Fu said, "Miss Ran, I have to go back to the monastery, and I have to go to school tomorrow." ”

"It's late at night, so come and stay at my house tonight, and let the coachman take you to the monastery early tomorrow morning." ”

"No, if I don't go back, I'm afraid the alumni will worry about what happened to me outside. ”

Hearing this, Ran Yun was no longer reluctant: "Then I'll send you to the gate of the monastery." ”

Chen Fu did not refuse, the two got into the carriage together, and the coachman waved his whip and drove towards the monastery.

On the way, Chen Fu began to settle accounts:

"Miss Ran, I borrowed ten taels of low-grade yuan stones from you to buy demon beast essence blood, three taels to buy stasis grass, white snow lotus and silver chalcedony flower, and that piece of fire copper essence seems to be worth ten taels, right? You only got four taels back, I should give you six taels. In this way, I will pay you back a total of nineteen taels, which is equivalent to nineteen thousand yuan. ”

After Chen Fu finished speaking, he handed over a 20,000 yuan money ticket.

Seeing that he looked serious, Ran Yun smiled, took the money ticket, took out one or two low-grade yuan stones from the prime minister's bag and threw them to him, and said quietly:

"Xiao Langzhong, you have calculated this account so clearly. So, can you help me calculate how much my life is worth?"

“......”

Chen Fu didn't understand for a while.

"You saved me in Biyi Mountain, and I owe you my life. You can help me calculate how much this life is worth, and I will return it to you!"

"This, this, this ......"

Chen Fu opened his mouth and stammered, and only after a while did he say authentically:

"To save people is to save people, to borrow money is to borrow money, one yard to one yard. ”

"Saving people is the right thing to do, Miss Ran must not be so concerned. ”

"Borrowing money has to be repaid after all, there is borrowing and repaying, and it is not difficult to borrow again. If I borrow money and don't pay it back, won't I become a coercion who wants to repay my kindness!"

Ran Yun frowned slightly, and his eyes were complicated: "You don't expect to repay your kindness, and I'm not ungrateful! How can I make you and me feel at ease?"

Chen Fu's head instantly grew big, and he felt that this question was a hundred times more difficult than the math questions in the entrance exam!

So he decisively pretended to doze off and never answered this conversation again.
