You Have a Spirit Spring, I Have Culinary Skills

Su Qiyan transmigrated into a book and became the real heiress. The story has reached the point where she has returned to her wealthy family's home. Unfortunately, this family puts profit above everything else and doesn't want Su Qiyan, who was raised in a modest household. Her biological parents said, "What do we need a daughter who can cook for? Can she make a useful marriage alliance or hook a rich man? All she has is the smell of cooking oil on her." Su Qiyan turned around and walked straight out. The fake heiress, Gu Niannian, knew she had taken someone else's place. She paused, then immediately packed her things and prepared to leave. But the Gu parents stopped her. The family was going through a rough patch and needed someone to invest in them. Unfortunately, Gu Niannian messed things up and offended an important person. Su Qiyan found Gu Niannian by the roadside. The young woman was crying helplessly, looking utterly miserable. Su Qiyan held out a large bun. "I made it. It smells great. Want some?" Gu Niannian looked up and recognized Su Qiyan. "...Can I?" Without another word, Su Qiyan put it in her hands. [Ding! Encountered the real heiress and supporting female character. Story progress unlocked. Spirit Spring Space activated. Bound user: Gu Niannian.] They both froze. [Task 1: Obtain an item from Su Qiyan to unlock a plot of farmland.] [Task 2: Get Su Qiyan to admit defeat verbally to unlock high-quality seeds.] [Task 3: Earn Su Qiyan's sincere acknowledgment to unlock interdimensional trade.] Gu Niannian: "Sister, how about we work together?" Su Qiyan: "Let's do it!" Content warnings: 1. The real and fake heiresses team up to achieve a win-win. 2. This is actually a farming and food novel. 3. Romance takes up very little of the story. I'm just a romance-writing disaster, lying flat. Theme: Work together for mutual benefit, stay true to your convictions, make money, and be self-reliant
