Cross-Time Besties Beat Famine

After orphan Iris passes away from illness, she transmigrates into a famine-era farming novel, becoming an orphan girl in Brook Village. The brazier in her home connects to the modern world, with the other end belonging to her female best friend Serena. The two exchange supplies and antiques bidirectionally through the brazier: Serena continuously sends seeds, agricultural machinery, and modern ingredients to Iris, while Iris sends Chen Kingdom antiques back to the modern world. Serena gets to know collectors through the antiques, gets hired at a private museum, gradually rises to the position of curator, and holds a special exhibition on Chen Kingdom culture. Relying on modern agricultural technology, Iris reclaims wasteland, manages flood control, cultivates high-yield grain and vegetables, builds greenhouses, opens Iris's Canteen and various handicraft workshops, leads villagers to form a cooperative, and resolves the famine. Emperor Kael of Chen Kingdom, who is traveling incognito, takes a fancy to Iris's abilities, issues an imperial decree to appoint her as Imperial Agricultural Advisor after returning to the capital, and orders the whole country to learn her farming methods. Later, the two open up a bidirectional travel channel, work together across time to run cultural & creative merchandise and farming industries, Iris's younger siblings also excel in their respective fields, and both sides across time gain successful careers and fulfilling lives.
