Upgrading Small Wooden Boats Relies on Recycling Garbage

Ship upgrade system 2002201, bound by Han Na. It starts with a small wooden boat, and it is difficult for two people to sit down. Fortunately, I can upgrade, but it actually relies on recycling garbage? Fortunately, the sea water in Huixing is rising, and the sea is everywhere, and there is countless garbage. Recycled lunch boxes have environmental value and can be spent as credit coins. This solved Han Na's urgent need and the pressure was much reduced. What's even more amazing is that the system's one-click recycling can actually recycle an entire garbage island? Does Han Na really have to work as a cleaner in another world and clean the entire Wheexing before she can return to her hometown? She got rich thanks to the system, but she wants to go home. They all want to go home! I don't want to be a savior here. Intention: Being kind to others is the most beneficial to oneself
