Deep-Sea Survival: From the Start, I Have a Submarine

Everyone wakes up to find they have transmigrated into an ocean world, each starting out with a submarine.

To survive, they must pilot their submarines into the deep sea to search for supplies.

Supply wreckage, treasure chests, sunken ships...

To find anything good, they have to dive deep. But the depths are home not only to terrifying sea monsters, but also to fearsome sirens.

People risk their lives to dive again and again in order to survive.

But Chen Mo gets a sign-in System from the start.

Day 1 sign-in: A submarine mechanical arm!

Day 10 sign-in: A pet giant octopus!

Day 100 sign-in: An undersea fortress and a squad of siren guards.

While everyone else dives into the depths for the supplies they need to make it through each day, Chen Mo is already living a luxurious and safe life.
