Monarch of Gluttony: System of Sin - Chapter 48: 48: Strategist

Feng Xuxu, a 21st-century professor of agriculture and biology, was in secret the mastermind behind a five-star hotel. Running back and forth between the university and the hotel, it's no wonder she worked herself sick. One moment she closed her eyes, and when she opened them again, she found herself in the body of a poor village girl who had just lost her mother and then her father.Fortunately, time-travel came with a perk, the almighty space ability. After toying with some seeds, she grew thousands of acres of high-yield grains and spent her leisure time cultivating flowers. Before she knew it, she had created a landscape of thousands of acres of flowers. Munching on fruit, she ended up with thousands of acres of orchards. When she craved some greens in the wintertime, she turned around to discover greenhouses covering thousands of acres. Feng Xuxu counted on her fingers: Spring Garden, Summer Garden, Autumn Garden, Winter Garden—not one more, not one less, four in total. She nodded in satisfaction and said, “This is all one needs in life.” Meanwhile, a certain devilishly charming man approached her with a sly smile, “Little Xuxu, how do you plan to deal with me?”Feng Xuxu was in disarray amidst the wind, realizing she had forgotten about one demon yet to be tamed.In this story, both male and female leads are strong, with the male lead being physically and mentally pure and devoted.

This is a world shrouded in darkness, and the pervasive black mist erodes all living beings.

Only fire can dispel the darkness and protect mankind.

But the firewood will eventually run out, the fire will eventually go out, and humanity will eventually perish.
