Douluo Dalu 2: The True God King - Chapter 13: [DD2]:

When natural disasters ran rampant, with extreme cold and storms spreading endlessly…When the world mutated, zombies surged like tides, and eerie horrors emerged…When the apocalypse descended, massive Devouring Abysses hundreds of kilometers in diameter began appearing around the globe…When people looked up at the atmospheric cloud layers and saw the slowly emerging corpse of a colossal evil god…From that day, people began to notice that daylight was arriving later and later, until the sun no longer rose, plunging the world into an unending polar night.For survival, on that day, the Apocalypse Radio made its final broadcast to the world:“Everyone, flee eastward—escape to dawn!”…Lin Xian awakened the [Mechanical Heart] ability. He could devour machinery to gain various mysterious skills, scan machines to obtain blueprints for manufacturing, and even use his thoughts to achieve unified control of different machines.Thus, he found a 200-ton heavy gas-powered locomotive, towing specially modified storage, planting, production, medical, and living carriages, and embarked on a 320,000-kilometer journey along the planetary orbital rail—charging eastward toward the dawn!

This is a world where a king is the most powerful.
