Wasteland Divine Artisan

Lu Chuan lives in Base 72, long looked down on for his low-ranked ability. By chance, he discovers that his power not only shields against contamination but can also restore corroded supplies. After accidentally absorbing a black crystal, his ability evolves and awakens a mechanical pulse cannon strike. From then on he proves his worth, earns respect, resolves the base's conflicts, takes over as leader, and guides everyone toward a stable new life.
