MTL - Medical Sovereign - Chapter 2180 ambiguous

The challenges a female cultivator had to overcome on her life journey were countless.

Before going to college, an ordinary high school student went to celebrate and got drunk. When he woke up, he found himself in a completely different world. There was a big sect, the approaching sect entrance examination, a slum where his body’s previous owner lived, and a shared memory about a missing young girl.

When he got tangled in a fight with a few punks in this different world, he fell off a cliff and miraculously found himself still alive, with two more voices ringing inside his head. They were Sword Master and Saber Master. In the company of them, he continued to find out more about this whole new world. He took the sect entrance examination, entered the sect, met a strange man in black, and even participated in a major competition of the sect to have a chance to win over his peers!
In this whole new world, he was born again and got to explore the fantastic martial world!

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!

In each world, there would be the ultimate blackened female lead called Lin Xia, and each of them would’ve drowned in the light of their first love, aka the moonlight. Unsurprisingly, all of these moonlights were beautiful, attracting the love and adoration of Lin Xia, but in each and every world, the moonlight would eventually leave in the end, ultimately causing the blackening of Lin Xia’s fragile heart.

Years later, when the blackened Lin Xia finally fell for another woman, the special memories of the moonlight which was buried deep within her blackened heart began to fade, replaced by the light of the true soulmate.

And when the memories of the moonlight faded to almost nothing, the moonlight returned abruptly, only to be rejected by the moved-on Lin Xia. Filled with a crazed sense of jealousy, the moonlight began to destroy the new couples’ lives, only to be hated entirely and finally, crushed cruelly by the angered female lead.

And this is where the story begins, as a world-hopper, Ye SangSang would complete her missions in these worlds.
