Yu Gengwu was a blogger with millions of fans of handmade videos in his previous life, and he traveled through time and became a dreaming hero in ancient times.
In order to save life, rub guns and cannons, and in order to improve the quality of life, rub salt, sugar and glass.
The industrial products he made at random attracted the attention of top people around the world.
The emperor of the Ding Dynasty wanted to marry his daughter, the empress of the Ji Dynasty would not marry him unless he was the emperor, and the young emperor of the An Dynasty even wanted to sacrifice his widowed mother.
Yu Gengwu sighed: It was not my original wish to achieve great things, my original intention was just to live!
