Xia Yu, a researcher in Huaxia, successfully invents a balanced-world quantum particle engine, hailed as the greatest invention of the millennium. In the struggle to seize his breakthrough, his parents, wife, and children are killed one after another. The immense tragedy shatters Xia Yu, and he falls into a vegetative state before being revived.
On a sudden impulse, he uses the quantum particle engine to transmigrate through the clouds and save his family, but by a twist of fate, he transmigrates to the Great Qin dynasty, a balanced world strikingly similar to the Qing dynasty. Heaven has a way of preserving life. Just when Xia Yu has fallen into despair once more, he encounters a woman who looks and acts exactly like his wife. To stay by her side for a lifetime and achieve greatness, he begins a life of reshaping Great Qin and waging war, restoring the empire to its former glory.
It's not bad, but there are many small problems.
