Demon Slayer: Daily Development of the Swordsman of the Light

[Single heroine] [Early transition] [Later invincibility] During the Warring States Period, two completely different geniuses were born to the Jiguo clan - Jiguo Yansheng and Jiguo Yuanyi. The elder brother Yan Sheng was obsessed with strength and pursued the ultimate in swordsmanship, and eventually fell into the ghost way and became the first string of the Black Death Mou; while the younger brother Enichi created the strongest Breath of the Sun and became the light of hope for the Demon Slayer Corps. They have a younger brother named Chen Xi, who walks on the edge of light and darkness, practicing the Breath of the Sun and the Breath of the Moon at the same time, and finally merges into a new breathing method - the Breath of Xi! When Black Death Mou's blade pointed at Yuanyi again, when Ghost Dance Tsuji Mukai's shadow enveloped the earth, Dawn finally stood on the stage of destiny. Is his existence the key to breaking fate, or the beginning of another tragedy? When the sun and moon shine in the same hands, the world will usher in a new dawn - or will it be eternal dusk?
