He was saved, but became a vegetable. Thirty years later, Zhang Huowang slowly awoke to find that his wife had been dead for ten years. His son and two daughters were all grown up, and he had one grandson and one granddaughter. Faced with the thirty years he had missed, Zhang Huowang was utterly bewildered. Smartphones, smart TVs, high-speed trains, airplanes, cars lining the streets, skyscrapers stretching as far as the eye could see... It was all completely unfamiliar to him. Fortunately, when he rescued those children, he had accidentally swallowed an unknown creature. It made his body different from an ordinary person's and left him with a new energy inside, setting him on the path of cultivation.
