Dragon Who Controls Time - Chapter 1558 - One Dream Transforms into Plurality, I Am the Only One in Infinite Space-Time!Final Battle (3)

I came from hell, looking for redemption! –“Revelation”

It’s like our clean birth, contaminated by the dust of one life, and then clean death.
Well, this is just a story. …

mc gets transmigrated to Fallout New Vegas with the merchant system. let the questionable adventure begin.

My name is Chen Mo, a gaming nerd.Recently, I've been obsessed with a single-player game called “Absolute Immortal” and have defeated the final boss, [Lady Yu], over a hundred times using cheats.Then, I transmigrated.I became Lady Yu's lackey.On my first day at work, why does it feel like Her Majesty is looking at me strangely...?...My name is Yu Youhan, Imperial Consort of the Yuan Dynasty, with immense cultivation power, dominating the nine provinces.I recently had a 'dream'.In the dream, I was wantonly tormented by a man, utterly powerless.I initially thought it was a mistake in my cultivation, thus giving rise to a heart demon, until that 'inner demon' appeared right in front of me......Within the high walls of the deep palace.'There are many ways to conquer a heart demon, it doesn't necessarily have to be through force...''Your Majesty, I, I admit defeat!''Who allowed you to admit defeat? Dare to defy this palace, and you'll be punished for another hour!''...'

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!
