Submarine Survival at Sea: I Have a Three-in-One System

[Survival + Not a Goody-Two-Shoes + System + Wish-Fulfillment]

A game played by everyone transported him to an alien world, trapping him beneath 500 meters of ice on the ocean floor.

From the start, all he had was a basic submarine.

Food, oxygen, water, even the diesel fuel that powered the vessel...

All kinds of ferocious sea beasts lurked in the ocean...

And deep-sea monsters hid in the depths...

Danger was never far away.

The only things he could rely on were the items he salvaged from seashells.

But opening a shell meant answering a multiple-choice question, and choosing wrong could produce an item that threatened his life.

Just as he was about to despair, Shen Lang discovered that he possessed a three-in-one System.

With his luck MAXed out, he could ignore the possibility of choosing wrong. Every choice he made was correct...

Shen Lang exclaimed, “I'm destined to become the Ocean King!”
