Jiang Yunshan transmigrated into a book and became a cannon-fodder supporting female character who wouldn't survive past the first chapter. Her timing was terrible, too: she arrived just as the story was about to kill her off.
The good news was that she was bound to a system for winning over the villain, and she survived by sheer luck. The bad news was that the only way to return to the real world was to win over Rong Heng, the notorious, ruthless villain, and get his favorability to the maximum.
To complete the mission, she joined the Tianyan Sect and became the villain's fellow disciple. Without meaning to, she brought her modern grindset to the cultivation world, juggling cultivation and her mission. Using her solid knowledge of math and science, she developed spirit ore, improved formations, and restored ancient talismans... She even found time to visit Rong Heng's residence day after day with little gifts to brighten his life.
Rong Heng had always preferred solitary cultivation, but every day this noisy little girl would show up, eyes full of hope, to give him something she'd made. He wanted to reject her outright, but a moment of softness turned into one concession after another. Little by little, he let her into his lonely, frigid world and grew used to her presence.
Later, when the entire cultivation world was plunged into a great catastrophe, his little sun risked her life to save all living beings. He had no choice but to cast aside the demon in his heart, stand by her side, and wield his sword to protect them all.
When peace returned, Jiang Yunshan's mission was complete. But Rong Heng, eyes red, clutched her hand and said, "Either stay, or take me with you."
Theme: Establish a heart for heaven and earth, and a destiny for the people.
