[Two male protagonists + patriotic science and technology literature + attack on rebirth + fictional history + 1v1] The cool and simple man-machine is attacked by the old-fashioned wild dog of the x dad (internal) Wen Jinliang comes from the interstellar era, As the youngest chief starship designer in history, he died suddenly and traveled through time to become an overseas-born young man in the ancient earth storybook. Good news: I have finally been reincarnated into a big family, and I can finally live without working and waiting to die. Bad news: heart disease, illegitimate child, no inheritance kind. Wen Jinliang landed in M ​​country, and the beginning of the collapse of heaven: he had no money to study in a foreign country, his sister abandoned her husband and son and left for a foreign country, and her patriarchal mother was struggling to make a living by digging wild vegetables with her cheap nephew whose father is unknown. Wen Jinliang calmed down and decided to return to China with what he had learned throughout his life and embrace the golden thigh of the country's father. Some years later, China's aerospace and military industries are in full bloom, and achievements are emerging one after another, gradually opening a huge gap with them, but no matter how you inquire and spy on information, you will get nothing. After Wen Jinliang handed himself over to the state, he made three stipulations with the leaders, one of which was - work from ten to five, and the lunch break should not be less than one hour. In the institute, countless academic masters denounced his arrogance and laziness. But he still went his own way, getting off work and leaving when the time came. No one believes his true identity, and even the spies who pass by him only regard him as the person with the strongest connection. An unexpected incident forced Wen Jinliang to stay up all night, and his already fragile little heart began to fail. He really couldn't work overtime - because he would really die.
