He Escaped Through the Years of Disaster and Became an Imperial Merchant.

Hu Yifan, a man from science and engineering, traveled back in time to ancient times, where natural disasters continued, droughts, blizzards, and foreign invasions forced him to flee into exile. Only when he got outside did he realize that this was not the world but hell. Fortunately, he had a space plug-in and a smart brain, and he made money all the way while escaping from famine. Finally, the escape was over. Hu Yifan led his tribe to become an imperial merchant, and created blueprints to do business in partnership with the emperor.
