With the help of the Jianneng Stone, the two of them had a very high efficiency in sweeping.

Few people came to these abandoned mines, so they did not meet anyone else. Of course, with the lessons of the past, they were very careful, for fear of being secretly followed behind. After all, Han Yang had the most talented treasure like the Stone of the Stone, if it was discovered, he would probably die in minutes. Therefore, he was extremely cautious.

The two people's sweep lasted for nearly two days.

Two days later, the faces of the two appeared in Yumei's shop.

Yumei looked at the two of them at this moment, and a strange color flashed deep in her eyes, but her face was full of smiles and said, "Oh, two guys, come today, what do you want?"

At this moment, there were no other customers in the store, only Han Yang and Zi Luo.

Han Yang looked at Yumei and smiled and said, "It's still the same as last time. I want to buy some medicinal materials that can promote the release of the true spirit!"

When Yumei heard this, a look of surprise flashed in her eyes again. She knew that these medicinal herbs were very expensive. There were really not many people underground. They could have so many energy stones. In such a short interval, they would buy this medicinal herbs. You know, Han Yang had already purchased seven spiritual herbs before.

She looked at Han Yang in surprise, and a few thoughts flashed in her eyes. Could it be that this guy has made a fortune again?

Thinking of this, she felt a little angry. Originally, she sent her subordinates to follow Han Yang and Zi Luo, but that guy was lost.

So, at this moment, she didn't know Han Yang's background, but after thinking about it for a moment, she had an idea. She looked at Han Yang with a smile and said, "Brother, are you talking about Yunling Grass?

Just so happen, we just got some here. If you want it, I will give you a little cheaper for your second visit!"

But Han Yang smiled and asked, "Apart from the Yunling Grass, are there any other medicinal herbs here?"

When Yumei heard this, her face changed suddenly, and a strange look flashed in her eyes. She looked at Han Yang with a strange expression and said, "Look at what you said, there are naturally some. However, Yunling Grass is the most basic medicinal material. The effect of other medicinal materials is much better than Yunling Grass. However, at this price, it is naturally rising. Ordinary people can't afford it!"

It’s not that she looked down on Han Yang, but that there are not many people who can buy the Lingxiang grass below, and those who can afford other medicinal materials are even rarer. The underground energy stones are rare resources. Most people may not be able to get one if they are searching for a few months in the mine. And after obtaining it, they still have to practice, so how can they be willing to take it out and buy things?

After hearing her words, Han Yang couldn't help but frown and said, "Oh, listen to you, do you underestimate me?"

Why, do you think I don’t have the money to buy it?”

Yumei was stunned, then immediately smiled and said, "No, no, no, brother, don't get me wrong. I don't mean this. It's okay. Since you want to see it, I'll take it out and show it to you!"

She is in business, and even though she knows that Han Yang is likely to be unable to afford it, she doesn't want to offend Han Yang.

As she said that, she walked to the cabinet behind, opened it, and took out two transparent bottles from it. Han Yang looked carefully and saw that among the two bottles, one was filled with a flower with a faint red flame, while the other was filled with a piece of black wood. On the wood, there was a faint black flame, flowing continuously.

When Zi Luo saw this scene, he was also shocked and shouted: "It turned out to be crystal flame flowers and black flame wood!"

Seeing this, Yumei smiled proudly, looked at Zi Luo, and then said, "This guy has a very good eye ability! That's right, these two medicinal materials are much better than those of Yunling Grass, and they are extremely rare, so the price is much higher than those of Yunling Grass!"

Han Yang asked, "How much does it cost?"

Yumei looked at him, a contemptuous smile appeared on the corner of her mouth, and she said lightly: "Jing Yanhua, price, two first-level medium-grade energy stones, black flame wood, price, five medium-grade energy stones!"

"What, medium-grade energy stone?"

When Han Yang heard this, he was shocked and asked in surprise.

A smug smile appeared on Yumei's face, as if Han Yang's reaction had been as expected by her. She smiled and said, "Yes, Jingyanhua and Black Flame Wood are both precious things, so the price is naturally high!"

Han Yang couldn't help but frown. They swept away the abandoned mine caves in the past two days. Although they had a lot of harvest, they all harvested were low-grade energy stones. They did not find medium-grade energy stones. What should I do?

When Yumei saw his expression, she smiled and said, "I have said a long time ago that these two medicinal herbs are still a bit expensive for you, so I still recommend Yunling Grass! Although the effect is a little worse, after all, it is better than none, right?"

At this time, Han Yang suddenly looked at her and asked, "Do you have to exchange these two medicinal materials for medium-grade energy stones?

Is it not possible to have a low-grade energy stone?"

Yumei's face changed, she looked at him for a few glances, and said, "The energy contained in the medium-grade energy stone is about ten times that of the low-grade energy stone. Moreover, the energy in the medium-grade energy stone is more pure. Therefore, if you want to exchange for the low-grade energy stone, it is not impossible. A medium-grade energy stone must be replaced by twelve low-grade energy stones!"

When Han Yang heard this, his brows frowned. This woman is too dark.

Zi Luo couldn't even stand it anymore. At this moment, he couldn't help but frown and looked at Yumei and said coldly: "Hey, you're a lion's mouth. Who doesn't know that the exchange rate between the medium-grade energy stone and the low-grade energy stone in the entire empire is ten. Don't you know if you bully us?"

But unexpectedly, Yumei heard this and smiled, looking at them and said, "There is no way. This is underground, not in the city above. Do you know how troublesome it is to get these two medicinal materials? Therefore, it is necessary to raise prices! This is a bargain price, refuse to bargain. If you have enough energy stones, buy it. If not, buy Yunling Grass. Yunling Grass. I can sell it to you at the last price!"

Zi Luo's face looked even more ugly, but he didn't say anything.

He had no choice but to have such a bad attitude. After all, there was only one shop underground.
