Bravely Travel into Ancient Times with a Weather Forecast System

Zhao Xuan traveled through time. Bad news: time traveled to ancient times. Good news: There's a system tied into it. Bad news: It's the weather forecast system… A weather system that can only explore various regions in ancient times, so what is the use of binding the weather system? Were there weather forecasters in ancient times? So, how should he stay employed in ancient times? Should he still take the imperial examination? Zhao Xuan originally thought that he would deal with literature for the rest of his life, but he didn't expect that he would be involved in a different kind of work. For example... A celestial master who reads celestial phenomena and divines? But what Zhao Xuan doesn't know is... His thoughts will be known to the whole world every time he reads the weather forecast. Motto: Don't be afraid
