"Are you selling this stone? I want three." Xu Xin went straight to the point.

"It depends on the conditions you offer." The other side is also very smart.

Xu Xin thought for a while and said, "You should have a lot of green stones. I have a lot of green wood here. I will provide you with 50 green woods to help you build the synthesis table. You give me 3 blue stones." Xu Xin directly took the initiative.

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

"60 greenwood, and I want your redberries."

One piece of blue-level stone in exchange for twenty pieces of green-level wood?

He still made money. After all, there was so much green-grade timber that he didn't even want to cut it.

"Yes, but you have to exchange the red berries for iron ore, and the price is what you said. 20 iron ores for one red berry."

"make a deal."

[The other party initiates a trade with you, Stone (blue)*3 in exchange for Wood (green)*60]

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

"…Three first."

Xu Xin initiated the transaction.

[You initiated a trade, Red Berries Large (Blue)*3 in exchange for Iron Ore (Green)*60]

[The other party accepted the deal and obtained Iron Ore (Green)*60]

[The other party initiates a trade with you, Stone (blue)*1 in exchange for None]

"Hmm?" Xu Xin was a little confused.

What does this mean? Are you going to give one to him?

"I'll give you one first. You should make a new axe quickly to chop down trees. After you've chopped down trees, I'll give you the remaining two." The other side explained.

It's a bit cute. Xu Xin couldn't help but smile. Did she trust a stranger like him so much right from the start?

However, it seems that she may have quite a few blue stones, perhaps as many as the red berries in his hand, otherwise she would not be so careless as to pay one in advance.

Xu Xin accepted the deal, gave her a good sign, and immediately made a new axe.

[Improved Stone Axe (Green): Can chop down trees of blue rank and below. It's tougher and sharper due to the addition of higher-grade stone. Durability: 200.]

It feels so good. I can actually cut down blue-level trees!

The other party's resources are strategic, so it seems that we must establish a good relationship with 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 I have the axe in my hand, it seems that it is time to cut down the blue tree.

…

On the other side, in a tree house that was a little smaller than Xu Xin's, a short-haired girl was carefully examining the red berries in her hand.

She was wearing a simple beginner's short-sleeved shirt and shorts. She had a tall figure, and her exposed white and firm arms and legs showed that she regularly exercised to maintain her figure.

"With the eyesight-improving effect, can I gain 2 hours of night vision?... As expected, 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 50 square meters. At this moment, Li Wenxi is on the second floor, sitting in front of the screen.

She walked to the first floor of the tree house and looked at the various stones and iron ores that filled the floor.

When she saw yesterday that the trading platform would be opened today, she knew that she should be able to trade for good things with these stones and ores, so she dug in the mines for a whole day, which really made her very tired.

In order to move these things, she walked 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 move all of them back.

But even so, her limbs were sore today, and her legs were shaking when she walked. After all, she had been mining all day and carrying heavy loads. Even if she exercised regularly, her body couldn't take it.

Therefore, she did not plan to go out again today. She planned to recover her body and use these things to trade for other supplies on the trading platform.

"This guy seems quite impressive. He's even built a synthesis platform. I spent half a day chopping trees yesterday, but didn't see a single green lumber. It was all white." Li Wenxi propped up his trembling legs and returned to the second floor. Lying back on the wooden bed, he sighed. "He's quite powerful, but it seems he doesn't have a source of iron ore. We should be able to cooperate."

Li Wenxi's tree house is located next to a mine, with a stream passing by.

She planted a tree house here because she thought there were both mineral and water resources here, and there was no point in walking aimlessly any further, so it would be better to take root here.

"It's a low tree house, only about 20 square meters and only one floor. Could it be that my tree house is more luxurious than theirs?"

She was just a sophomore who woke up in this unknown world.

To be honest, she was not well prepared for how to survive in this world, and it still didn't feel real to her.

But she still felt secretly happy knowing that her tree house was more advanced than others.

"I wonder what that guy's tree house looks like. Maybe mine is better!" Li Wenxi felt happy and continued to lie on the bed sideways, flipping through the text in the chat room.

So far, only Xu Xin has asked about her iron ore.

Come to think of it, after all, at this stage, most people haven't even made a synthesis table.

The level of materials can only be identified using an identification table, which means that survivors can only rely on luck to obtain materials. Therefore, iron ore is useless to most people at this stage.
