This novel is also known as Deep Ocean Survival: A Submarine From The Start

The whole people traveled through, and everyone was trapped in the ocean abyss two thousand meters below the alien ice layer!

There is only one basic pioneer ship at the start!

Food, oxygen, water pressure…
Unpredictable seabed turbulence…
The powerful and terrifying Abyss Siren…
Evil and mysterious parasitic flora…

With all kinds of potential threats that follow everywhere, this road to survival is doomed to be extremely difficult!

However, when everyone was desperate for the hardships of survival, Meng Lei was calm and composed.

Because he found that he could actually see the system prompt!

“At a distance of 500 meters, a shipwreck of an alien pioneer was found, and the supplies inside are enough to make you rich!”

“At a distance of 1200 meters, I found a doomsday worm, rush up and kill it, and you will become the brightest cub wandering in the dark abyss!”

“The distance is 4,500 meters, and the ruins of an alien civilization are found. The danger level is SSS! Why are you standing still, turn around and run!”
