After putting away the Heaven, Earth, and Human Three Powers Swords, Ling'er drew the last two black-and-white swords again.
``` Yin Sword · Wangshu
Form: The blade was slender, roughly three feet five inches long, with an extremely narrow spine and edges as thin as cicada wings. The guard formed a crescent, its ends curving upward like a waning moon.
Color: The entire sword was ink-black, darker than night itself. Silvery-white cold light flowed slowly across its blade. An eerie blue gleam shone along its edges, a concentration of supreme yin power.
Patterns: Both sides of the blade bore intricate lunar markings, arranged from guard to tip in twenty-eight rows corresponding to the Twenty-Eight Lunar Mansions. Exceedingly fine ice-crack patterns spread between them.
Aura: When drawn, it caused the surrounding temperature to plummet, condensing moisture in the air into frost. Dim shadows drifted around the blade, as though countless whispers were sounding beside one's ears.
Sword intent: "Supreme yin is solemn and cold; supreme yang is blazing and bright." The utmost yin, the limit of cold, the deepest darkness.
Yang Sword · Xihe
Form: The blade was broad, roughly three feet eight inches long, with a thick spine and outward-flaring edges. The guard resembled a solar disc, with a crimson-gold crystal embedded in its center, as though a sun were burning within.
Color: The entire sword was crimson-gold, like the blazing midday sun. Platinum-colored flames of light burned across its surface. An almost white radiance blazed along its edges, embodying the pinnacle of yang.
Patterns: Both sides of the blade bore layers of solar markings, spreading from guard to tip like sunlight radiating in every direction. Golden flame patterns wound between them.
Aura: When drawn, it sent heat waves rushing into one's face, distorting the surrounding air and instantly withering
