MTL - Fight To the Third Generation - Chapter 961 large walkman

In the year Jin Stratus was born, Humanity had long since conquered the stars, with their sights now set on a cosmos filled with unimaginable horrors.Yet in a universe that is but one bubble in an endless sea of realities, on a worthless blue planet beneath a crumbling city, a slum rat named Jin Stratus awakens to his destiny.When the “Door to the Myriad Worlds” descends, Jin steps through, armed with nothing but his unyielding will and his innate comprehension-defying talent—“Against-Heaven’s Understanding.”In the Great Universe of the Starry Sea, where ancient beings can erase galaxies with a sigh and traverse endless light-years in a single stride, Jin is nothing but dust. But with each battle, each world, and each bloody step, he transcends the world that seeks to oppress him, forging himself into a being unrivaled across all realms.[Your Understanding is Against-Heaven.]-You have comprehended the “Bone Marrow Blood Tempering Divine Technique.”-You have evolved “Fist of Falling Thunder” into the “Thunder World Creation Technique.”-You have witnessed the collapse and rebirth of worlds, grasping the “Cosmic Palm Domain.”-You have obtained the “Limitless Incarnation Method.”From the gutter alleys of the Lower Slums to the endless cosmos, Jin Stratus will ensure the world remembers his name—For throughout heaven and earth, he alone… can comprehend it all.And he alone will become the strongest.

Oosuki Masato is an ordinary high school boy who is magically transported to an alternative world, but for some reason his doting, over-protective mother comes along as well.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

There was no warning and it took them by surprise when the meteorite hit the earth. They thought they were doomed, but they managed to survive the apocalypse. They lost billions of lives because of that incident, and it took them decades to be able to stand on their own feet, but when they thought that they were fine, they were wrong. They found out that the meteorite brought something with it, they discovered a species and they called them Extrateressterial Parasite. It devoured and consumed anything that was alive, and they realized that the apocalypse was just the beginning of their suffering.

After centuries of trying to survive, Archie Lancaster the one who believed the end of humankind could be changed decided to do his best and tried to become one of those people that prevented humankind from extinction. His path wasn't easy nor peaceful, nothing could be described what kind of experiences he had been through.
