[Tang Dynasty] Choose Princess Pingyang at the Beginning

Chi Xingqiu has always felt that he is a salty fish waiting to die. This is even more true after he won the lottery and achieved financial freedom. But one time when he opened the door of his bedroom, he got the space-time door inexplicably. The beautiful Tang Dynasty that countless people missed was displayed in front of him. The problem is that Chi Xingqiu himself, who is useless at everything, doesn't want to have this opportunity at all. Facing Princess Pingyang who 'invited' herself to the General's Mansion as a guest upon meeting her, Chi Xingqiu just wanted to shout: Help! At this moment, the wheel of history changed its direction. Princess Pingyang: Do you know how to make gunpowder? Chi Xingqiu: I will tell you after I go back to check. Princess Pingyang: What about the telescope? Chi Xingqiu: I will tell you after I go back to check. Princess Pingyang: Soybean oil, you know how to extract soybean oil, right? Chi Xingqiu (drinking tea leisurely): I know you are in a hurry, but don't be in a hurry. I'll check the information when I get back to modern times and tell you when I get back. Princess Pingyang (smiling on the outside, crazy on the inside): It takes a lot of time for you to go back and forth, what use do I need from you! PS: Romance with a male protagonist, but please note that men are weak and women are strong. Pps: non-historical, parallel time and space. I don't have a good history, so please don't do any research. If you say it, you are right. Mission: Create happiness through hard work
