In the real world, Lin Nian traveled through time and became his character Su Wuxin, coming to the world before Yang Yitan and the Mask Group were destroyed. The panel warned her: If you try to change the plot, you will have to pay the price. She is just an outsider and has no reason to sacrifice anything for people in a strange world.
Until she saw with her own eyes the high-spirited looks of those young men - the hands holding out their coats in the wind and snow, the smiles raised while practicing swordplay under the moonlight, and Yang Yitan's soft words, "I want them all to live."
She decided to take action. The first time she changed a detail, the cost was that half of the panel disappeared. The second time, she tried to change bigger events, but found that her intervention was useless - the world was correcting the plot, and her efforts were like hitting cotton. The third time, she tried her best to protect someone, but couldn't, and the spiritual platform began to collapse.
She had nothing left. But she followed them outside the circle.
On the battlefield mentioned briefly in the original work, she exhausted her last spiritual platform and still could not save anyone. So she chose the last path - to cast her soul with blood, using her own life to awaken the mask group's power to stand up on its own.
The mask group came back alive. Su Wuxin died outside the circle. Lin Nian in the real world has forgotten everything. But traces of her existence remain in that world. The wind remembers, and the teenagers remember.
Intention: This is a redemption that we are still willing to run for even though we know the outcome. Tell those gentle and righteous young people - your light should not be extinguished outside the circle.
