Great Navigation: Inventing the Master Ball at the Beginning

Al traveled through time to become a member of the Naval Scientific Research Base and awakened the Wanjie Manufacturing System! The system randomly draws and gives a new invention unconditionally every day! As long as you complete system tasks and get recognition for your invention, you can receive a large number of system rewards and even lottery draws! "This is a master ball that can capture Neptunes! How can one thousand be enough? Let's get 10,000!" There is also the Wind-Fixing Pill that allows ships to avoid large tsunamis. A water-repellent bead that allows Devil Fruit users to avoid the side effects of sea water... Each item with magical functions was invented by Al, and the Navy, Yonko, and Shichibukai fought for it... The whole world went crazy! This novel and its characters are purely fictitious.
