What? Immortal Master, You're Saying You Were My Childhood Friend?

A final letter, a single line of longing, and all the world’s partings laid bare. A broken sword, a torn sleeve, and the heroes of ten thousand generations brought to their knees. “May you reclaim the wings of your dreams, soar beyond the heavens, gather the stars into your dreams, and make the crescent moon your bed. Promise me you’ll find the boy you once were: proud and full of spirit. Take the sword in your hand and strike down every injustice under heaven. Bring peace to the human race once more! And now, I’m leaving. This time, it really is goodbye. I’ll become specks of starlight and accompany you for the rest of your life...” Looking at the graceful handwriting on the letter, the young man seemed to see his immortal master standing beneath the peach tree once more, smiling at him. The words were finished, the paper yellowed, but empty of tears; each spot was full of longing. The young man carefully tucked the letter away and gripped the sword in his hand. Unprecedented determination flashed in his eyes. The boy who had once fought the Great Dao with nothing but a sword, smiling as he looked down on the heroes of the world, had returned! This time, carrying his master’s hopes, he would protect all living beings once more. Heaven and earth are a chessboard, and all living beings are the pieces. On the stage called the Heavens, four great factions make their entrances. Who will emerge victorious, and who will claim the prize?
