The Tale of the Caged Butterfly

Above the starry sky lies a mysterious road called the Heavenly River Path. They say it can take you anywhere, including heaven and hell, the past and the future. One day, a boy awoke on the grasslands. With a feminine face despite being a boy, he had no memories at all. He could only rely on instinct and the guidance of books to struggle to survive, wandering the world. In the martial world, he was misunderstood and hunted by the entire realm. Through one trial after another, with the help of good friends, he reclaimed his identity, defeated his enemies, and set foot on the Heavenly River Path.

Legends of sages are told along the Heavenly River Path. Whenever an apocalyptic calamity descends, a sage appears to put an end to every disaster. Now calamity is nigh, and the kindhearted boy is forced to take up his sword and fight alongside his companions across the four corners of the world. They brave heaven and earth, battle the Nine Hells, drive out demons, subdue spirits, and match wits with masters from every faction in life-and-de-death struggles. After many strange encounters, he finally uncovers the secret of the sage, but it also heralds the imminent arrival of the most terrible calamity.

A prophecy says that when the butterfly completes its final metamorphosis, the true savior will take the battlefield. Can this boy, burdened with a special destiny, save a sky stained red with blood?
