The Reborn Sci-Fi Boss

I simply wanted to save some private money and didn't want to live a miserable life in the future, but I didn't expect to save a whole country! I am an otaku who is addicted to games. Unexpectedly, I became a technology tycoon by chance, mastering the world's top technology. The emperor saw me and said, "Boss, do you still have the medicine?" My wife saw me and said, "You are heartless, my daughter is hungry!" My daughter saw me and said, "Mom, daddy is ignoring me again!" My son saw me and said, "You're peeking at others again. It's so immoral!" My name is Zhang Jiang, the "Zhang" from Zhang Chang, and the "Jiang" from Rivers and Seas. Don't ask me why I have this name. It's your fault if you ask. We are all primary school students, so be mature. Where do I have time to explain to you? I have to make medicine and wipe the children's butts!
