I Was Reborn in Ling Cage to Practice Martial Arts and Cultivation

[Reborn] [No System] [Doomsday] Reborn Chen Xuan arrives in the apocalyptic world of Spirit Cage. Drawing on his knowledge of the future, he creates the "Martial Source-Quality Flow" system. He combines genetic technology, the hidden power of traditional martial arts, and Eastern mysticism to temper his body and fight the Polar Devourers. In the ruins of Jiuchuan City, he meets Bai Yuekui, a formidable and cold-blooded source-quality wielder. Together, they face a King-class Polar Devourer that has awakened ahead of schedule.

During their escape, they rescue Jingnan, a mechanical warrior woman, and venture into the Valley of Death, where they encounter Aye, a boy from Dragonbone Village who has been corrupted by geomagnetism and Mana. Chen Xuan destroys the altar of flesh and blood, but is branded by a Mana Giant. To break through to the Metamorphic Realm and escape its tracking, he summons a martial tribulation of lightning to temper his body, then takes on the Lighthouse's Dawn Iron Cavalry mech corps head-on, exposing the truth behind their extraction of life's source quality.

At last, Chen Xuan activates the "Martial Seed of Fire" base beneath Dragonbone Village, obtaining humanity's ultimate hope for fighting Mana. He enters the floating fortress Lighthouse alone and uses his power in the Metamorphic Realm to rewrite the source-quality logic of its core, the "Clotho System." He drives back the pursuing King-class monster and even shakes the "Three Great Laws" that imprison human nature. As his silver hair flies, the golden Taiji pattern on the back of his hand foretells that humanity's salvation may begin with martial arts tearing through the darkness.
