Sail into Investment Season 4 with New Ships, Explorers, and Autumn Events

• Special autumn-themed events to run through October

After mastering the new Production feature, players can dive into a fresh chapter of *Uncharted Waters Origin* as Investment Season 4: Eastern Wave sets sail. This update spotlights legendary Ming Dynasty navigator Zheng He and runs until December 14th, making it a perfect entry point for fans seeking a rich naval exploration experience and long-form trading strategy gameplay.

Season Four sends you across the South China Sea, featuring historic ports such as Quanzhou and Macau. Here, you can trade exclusive goods like giraffes, luxury fabrics, textiles, and livestock—ideal for players searching for immersive maritime trade simulations and ocean-voyaging RPG adventures.

The new Great Adventure activity debuts this season as well. Each day, geographic coordinates delivered to your in-game mailbox lead to Land Exploration sites. Completing these expeditions earns valuable Season Investment Certificates and the Grade 25 Build Request, both essential for advanced shipbuilding.

Five powerful Grade 25 ships join the lineup: the Large Corvette, Soleil Royal, San Felipe, Large Fu Ship, and Djong. Crafting them requires Grade 25 materials plus a Grade 25 Build Request or an enhanced Grade 24 vessel, offering deeper progression for players who enjoy high-end fleet construction.
