Transmigrating into the World of Immortal Heroes

The protagonist retains memories of modern life. In his previous life, he was an experienced mechanical engineer with an in-depth understanding of mechanical structures and principles. After transmigrating, he gains a special constitution: dual Wind and Thunder spirit roots. These two spirit roots are relatively rare in the world of immortal cultivation, and complement each other, enabling him to practice unique Wind and Thunder techniques and unleash powerful spells.
