Qing Han, the most disciplined senior sister of the Yunmiao Sect, and Feng Ci, the most unruly demon emperor of the Phoenix Clan in the Ten Thousand Demon Valley, are parallel lines that will never intersect on their spiritual path - she believes in "different paths for humans and monsters" as her guideline, while he scorns "clear rules and precepts".
Ling Qingxuan was Qinghan, and his name was mixed up.
However, due to a demon conspiracy, the two accidentally met under the Demon Locking Tower. She went into danger to save her master, and he sought help from an old friend. The ice mist of the Frost Sword and the golden red of the Nirvana Fire created a strange tacit understanding in the light and shadow of the sword.
From late-night plotting in the Sutra Pavilion, to chatting under the Phoenix Vine in the Valley of Ten Thousand Demons; from joining forces to break the Dan Sect's rebellion, to jointly guarding the Three Realms Soul Guarding Formation; from the Heart-Burning Trial in the Phoenix Clan's forbidden area, to the sound of swords proving one's heart at the Taoist Forum - what they broke was not only the stereotype of "humans and monsters have different paths", but also the shackles in their own hearts.
When the phoenix flame holy sword recognized its master, when the jade pendants of the same heart agreed with each other, when he knelt on one knee and handed out the phoenix feather ring at the Nirvana Festival under the red cliff, she finally understood: the true practice is never to stick to the rules, but to follow the direction of the heart and follow the past; the true guardian is never to fight alone, but to dare to brave the storms of the three realms with one person side by side.
Later, the phoenix vines of the Yunmiao Sect covered the bamboo frame, and the cubs in the Ten Thousand Demons Valley would memorize the Pure Heart Art of the Yunmiao Sect. Their child Feng An, with the phoenix mark on his forehead and a cloud-patterned jade pendant in his hand, grew up in the fireworks of the two worlds.
This is a story about breaking prejudice, about the promise of guarding side by side, and about how red clothes and mysterious robes, coldness and heat, have turned "different paths" into "the same destination" over the long years.
