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

She placed all the blue-quality supplies on the second floor where she was currently.

On the identification table next to her, there is an ore that looks slightly different from ordinary iron ore and emits a blue light.

Because she has stones (blue), her tools can collect blue materials, so she can get materials that others cannot get.

[Iron Ore (Blue): When smelting iron ore, just add one piece to make Iron Nugget (Blue)!]

Just then, Xu Xin sent her a message.

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

…

Go back a few minutes.

On the other side, Xu Xin came to the tree house with the newly made stone axe (green).

Half of the area under his tree house had not been cleaned up yet. It was basically poplar trees, with half white and half green.

He swung his axe and chopped down the nearest poplar tree (white).

“Crack!”

The poplar tree snapped and fell to the ground, breaking into five pieces.

"Is this true?!" Xu Xin's eyes lit up slightly as he looked at the axe in his hand which had become much sharper.

He clearly remembered that it took five strokes to cut down the white quality poplar trees.

He chopped at another poplar tree (green), once, twice.

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

"...This is too powerful!" Xu Xin exclaimed.

Five times the efficiency, one axe is equivalent to five axes, is this the power of blue quality supplies!

This is much more useful than red berries!

If he can finish the work efficiently during the day, he doesn't want to work overtime at night!

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

Because it was right under the tree house, there was basically no need to carry 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]

It works, it seems, as long as the materials are in the tree house, they can be traded anywhere.

[The other party accepted the deal and received 2 stones (blue)]
