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.

”What is justice? What is evil? If given a second chance, I would no longer care about the opinions of others and only seek immortality.“With a cry to the heavens, Dusk Vale met his tragic end.But fate had other plans. He was granted a mysterious power that sent him back 300 years to the moment everything began.In this new life, he would live without concern for the judgments of others. No more restraint, no more hesitation — he would use any means necessary to achieve true immortality.What is the best villain? In my opinion, it is someone who does a lot of evil but is still considered a good person by some people. Someone who never really thinks about others but has many people who are loyal to him.Can one person defeat the entire world? Stupid, humans are born on the same level; surpassing one person is already not easy, let alone surpassing all of them combined. That is why Dusk will absolutely not act alone in this life.
