Age of Discovery: From the Start, I Invent the Master Ball

El transmigrates and becomes a member of a Marine scientific research base, where he awakens the Myriad Worlds Manufacturing System!

Every day, the System randomly selects a new invention and gives it to him unconditionally!

As long as he completes System missions and gets his inventions recognized, he can earn heaps of System rewards, and even chances to draw prizes!

"This is a Master Ball that can capture Sea Kings! A thousand isn't nearly enough. Make it ten thousand!"

There's also the Calm Seas Pill, which lets ships brave even the fiercest tsunamis.

And the Water-Avoiding Pearl, which protects Devil Fruit users from the side effects of seawater...

El invents one wonder after another. The Marines, the Four Emperors, and the Seven Warlords all scramble to get their hands on them... The whole world goes mad!
