As Zhang Wei returned from the spiritual realm with the Keeper's warning, he knew they faced an impossible choice. Li Mei's bond with the Phoenix had grown so strong that separating from it could mean losing her life. Shen, too, understood the danger, and offered to use his remaining strength to help, though he knew it could cost him his own life.
The shadowy figure that had followed them revealed itself at last—a being known as the Voidwalker, an ancient enemy of the Keeper. The Voidwalker sought to plunge the world into chaos, using the imbalance between the realms to consume both Heaven and Earth.
In the final battle, Li Mei, Zhang Wei, and Shen fought valiantly, but the Voidwalker's power was overwhelming. Realizing that only by restoring balance could they defeat it, Li Mei made the ultimate sacrifice. She offered herself to the Keeper, allowing the Phoenix's flames to be extinguished and restoring balance to the realms.
With the Phoenix's power gone, the Voidwalker was banished, and the realms were stabilized. But Li Mei's spirit, too, began to fade, her body no longer able to contain the energy it once held.
In her final moments, Li Mei smiled at Zhang Wei and Shen, knowing that she had fulfilled her destiny. The Keeper of Balance appeared before them, offering a final blessing—a promise that Li Mei's sacrifice would not be in vain, and that her spirit would live on in the flow of energy that connected all things.
