"Are these stones for sale? I want three." Xu Xin got straight to the point.

"It depends on the conditions you give." That person is also very smart.

Xu Xin thought for a while and said: "You should have a lot of green stone blocks. I have a lot of green wood here. I will provide you with 50 green wood to help you build the synthesis platform. You will give me 3 blue blocks."

Stone." Xu Xin directly turned against the guest.

He didn't reply for a long time, probably because he was thinking.

"60 green wood, and I want your red berries."

"Yes, but the red berries need to be exchanged for iron ore, 20 iron ores for one."

"make a deal."

[The other party initiates a transaction with you, stones (blue)*3 in exchange for wood (green)*60]

Is it so resolute? Xu Xin reluctantly canceled the transaction and said: "I don't have that much green wood now, so I have to go down and chop some. Let's trade berries first. How many do you want?"

"...Let's start with three."

Xu Xin initiated the transaction.

[You initiated a transaction, red berries·big (blue)*3 in exchange for iron ore (green)*60]

[The other party accepted the transaction and obtained iron ore (green)*60]

[The other party initiates a transaction with you, stone (blue)*1 in exchange for nothing]

"Huh?" Xu Xin was a little confused. What do you mean? Do you want to give him one?

"I'll give you one first. You quickly make a new ax to chop down the tree. When it's finished, I'll give you the remaining two." The other person explained.

It's a bit cute. Xu Xin couldn't help but smile, but it seems that the blue stones on her side may not be too small, and may be as large as the red berries in his hand.

Xu Xin accepted the deal, sent her a good one, and immediately made a new axe.

[Improved version of the stone ax (green): It can cut down trees of blue level and below. It becomes tougher and sharper because of the addition of higher-grade stone, with a durability of 200.]

I feel so comfortable that I can actually cut down blue-level trees! It seems that I need to have a good relationship with this Li Wenxi.

He suddenly remembered that he had also found a blue-grade poplar tree. The function of blue-grade wood may be similar to that of blue-grade stone. Now that he had this ax in his hand, it seemed that it was time to put that

A blue tree was cut down.

…

On the other side, in a tree house that is smaller than Xu Xin, a girl with short hair is carefully looking at the red berries in her hand. She is wearing a simple novice short-sleeved shorts, with a tall figure, and her fair and tight body is exposed from outside.

It can be seen from her arms and legs that she regularly works out to keep in shape.

"With the eyesight effect, can you get 2 hours of night vision? It's true, blue-quality items do have additional abilities." The girl murmured to herself.

This is a two-story tree house, with each floor covering an area of ​​about fifty square meters. At this time, Li Wenxi is on the second floor, sitting in front of the screen.

Li Wenxi walked to the first floor of the tree house and looked at the various stones and iron ore piled up on this floor. When she saw yesterday that the trading platform would be open today, she knew that she should be able to trade these stones and ores for good things.

So after a whole day of mining work, she was really tired.

In order to carry these things, she went back and forth countless times. Fortunately, her tree house was very close to the mine, and her physical fitness was much better than that of ordinary girls, so she was able to carry all these things back.

But even so, her limbs were sore today, and her legs were shaking a little when she walked. After all, she had been overloaded with transportation all day long, and her body couldn't bear it even if she exercised regularly. So she didn't plan to go out again today.

I want to trade these things for some other materials on the trading platform.

"This guy seems to be very powerful. The synthesis platform has already been manufactured. The trees that were cut down for a long time yesterday didn't even have a shadow of green wood. They were all white." Li Wenxi held up her trembling legs and returned to the second floor.

Layer, lay back on the wooden bed, and sighed, "He is a big boss, but it seems that there is no source of iron ore, so we should be able to cooperate with him."

Li Wenxi's tree house is located next to a mine, and there is also a stream passing by it. She stopped when she walked here because she felt that there are two resources in this location. If she continues walking aimlessly, she might as well take root here.

"The low tree house is only about 20 square meters and has only one floor. Could it be that my tree house is more advanced than theirs?" Li Wenxi was a little happy in her heart. She was only a sophomore student, and she woke up

Into this unknown world.

"I don't know what that guy's tree house is like, maybe mine is better!" Li Wenxi felt pleased with herself and continued to lie sideways on the bed, reading the text in the chat hall.

So far, only Xu Xin has been interested in her iron ore, and that's probably true. After all, no one has even made a synthesis platform at this stage. They can only use the identification platform to identify the grade of materials. As a result, the survivors can only rely on deception to obtain materials.

Therefore, iron ore is useless to most people at this stage.

"If that anonymous guy is really trustworthy, then it's not impossible to sell him a few pieces of blue iron ore." Li Wenxi couldn't tell anything from the chat room, so her thoughts returned to Xu Xin.

She put all the blue-quality materials on the second floor. At this time, there was an ore on her identification table that looked obviously different from ordinary iron ore, emitting blue light. Because she had stones (

(blue), her tools can collect blue materials.

[Iron Ore (Blue): When smelting iron ore, you only need to add one piece to produce iron nuggets (blue), which is affordable and easy to use! 】

Suddenly, Xu Xin sent her a message.

"Hey, why did this guy come back so soon?"

…

On the other side, Xu Xin took the newly made stone ax (green) and came to the tree house. The bottom half of his tree house has not been cleaned, and it is basically filled with poplar trees, with half white quality and half green quality.

He swung the ax and struck the nearest poplar tree (white).

"Crack!"

The poplar tree broke in response, fell to the ground and broke into five pieces.

"Really?!" Xu Xin's eyes widened as he looked at the much sharper ax in his hand. He remembered that it took five blows to cut down a white-quality poplar tree before?

He chopped down a poplar tree (green) again, once, twice.

"Crack!" The poplar tree (green) fell down forever.

"This... this is too strong!"

Five times the efficiency, one ax is equivalent to five axes. Is this the power of blue quality materials? This is not much more useful than some ghost red berries!

So Xu Xin, like the god of war, chopped down all the remaining trees under his tree house, and the ground was covered with white and green wood.

Because it was right under the tree house, there was basically no need to move it. He just needed to grab the wood and let the tree house take him up. Soon, he piled all the wood on the first floor and then initiated a transaction with Li Wenxi.

.

[You initiated a transaction, wood (green)*60 in exchange for stone (blue)*2]

Sure enough, it seems that the materials can be traded no matter where they are as long as they are in the small tree house.
Chapter completed!
