"Is this the treehouse core?" Lou Fei'Er's eyes sparkled as she looked at the treehouse core in Yan Haoming's hand, then glanced at him suspiciously, "Is this for real? Isn't it said that the treehouse core can only be obtained with a blue-level axe? Where did you get a blue-level axe? Is this really a treehouse core?"
To make a blue-level axe, you at least need a piece of blue-level iron and blue-level wood.
Blue-level wood is relatively easy; after all, everyone can buy blue-level fertilizer from the points mall and grow it themselves if they can't find it.
But blue-level iron is not so easy to find.
Currently, there is basically no blue-level iron being sold on the market.
This thing is worthless here, but in other regions, it's extremely rare.
To be honest, if it weren't for Li Wenxi, Xu Xin probably wouldn't have even seen blue-level iron.
