We Agreed to Practice Martial Arts, but How Did You Light up the Starry Sky?

The spiritual base sky rail separates the world into clouds and abyss. Born as an abandoned citizen of the abyss, Lu Chen's talent test result was dazzling [Lightless] - martial arts has no roots, powers are silent, and magic is insulated. Until he dug out a broken knife wrapped around star corpses deep in the ruins. The name of the sword is "Guixu", which is engraved with the true names of thirteen dead stars. When his blood soaked the blade, the silent star pulse in his body pulsed for the first time. It turns out that his spiritual roots were never incomplete - he just needed a starry sky that was vast enough to completely ignite. From then on, his martial arts was forged with fallen star cores. His enemies will be lost in the flowing sword light of stars. His path starts from the humblest abyss and goes up, breaking all established boundaries and cages. "They say that the sky's rails are impassable and that spiritual veins are destined to pass through." Lu Chen raised his sword to the sky, and thirteen star rings behind him lit up one after another. "Then I will use this blade of return to the ruins for this solidified world——" "A new beginning."
