In the Deep Sea World, I Own a Flesh and Blood Submarine?

[Fear of the Deep Sea] [Survival] [Submarine Evolution] [Suppression] [No Female Protagonist] Young Jiang Yi stopped breathing on the hospital bed. When he opened his eyes again, he found that he had traveled to another world. Here, the mainland has become a legend, and all human beings have moved to the sea to survive. If they want to survive in this deep sea, the only thing people can rely on is the submarine under their seats. Others control a cold steel submarine, but Jiang Yi controls a flesh-and-blood submarine that can hunger, grow, and "evolve". But this is not a free gift. In addition to fighting monsters swimming in the deep sea, he also has to be hunted by the forces of the deep sea. What is even more frightening is that the horrific disaster on the sea level seems to have begun to slowly sink due to his arrival. Under threats from many sides, all Jiang Yi can do is to keep devouring, evolving, and surviving until he reaches the bottom of the abyss.
