MTL - Comprehensive: Joan of Arc Came To the Door, Begging Me To Go To the Holy Grail War - Chapter 52

An ordinary student accidentally traveled into an other universe and became the king of a small kingdom. He had gotten a “Cheating Code” of life and was able to complete something extraordinary. This is the story about a king that was able to conquer continents and leave behind him an ultimate legend that will be recited between every generation to come.

Bai Yuxue floated in the world for decades as a soul, and was reborn once.

Excited, she immediately hugged the baby girl in her arms: “I just want to take my daughter to be beautiful alone!”

In difficult times, she lived in poverty and lacked food and clothing. She was an orphan, a widow, and a mother without support. Can anyone step on it?

Don’t be afraid, there is a simulated ranch management space that you bring with you. Move your fingers, make a fortune, and get rich again, and you can’t climb high in the blink of an eye.

Since then, Bai Yuxue has set a small goal for herself: to make her daughter’s daughter fat and happy as quickly as possible.

But, where did this man come from?

Bai Yuxue: “Sir, my man is already dead, don’t try to pretend.”

Someone: “Because I miss you, I borrowed from the King of Hell for another lifetime.”

Through the wind and rain, overcoming thorns and thorns, just to hold you in my arms again.

Bai Yuxue: “Well, let me slow down first.”

Little girl: “I hate you, don’t rob my mother from me!”

...[Inside an underground basement]“You are going to die for nothing, hahahaha,” the old man's voice thundered through the room, sending chills down my spine.Step.With a swift and ruthless motion, he lunged forward, his sword slicing through the air and slashing my throat, crimson droplets staining the darkness.“We'll see,” I whispered defiantly, my final words escaping as a mere breath against the impending darkness.Slowly, inexorably, my consciousness slipped away, and I descended into a deep, unfathomable slumber.“Huh!?” My eyes fluttered open, and I found myself seated in a bustling tavern, the air thick with laughter and the clinking of glasses.In front of me stood a captivating lady, her beauty juxtaposed with an angry furrow upon her brow, threatening to shatter the harmony of the jovial scene.“Don't follow me around!” Her words pierced the air like shards of ice, the intensity of her emotions palpable as she cast a resentful glare in my direction, before swiftly departing from the tavern....Am I trapped within the confines of a game? The fragments of my shattered common sense scattered before me, leaving me to question the very fabric of my reality.
