The last one is the planet with the letter F that Shuangshuang mentioned. The F-series planets are all either harsh environments or have particularly ferocious planetary life forms.
The safety of these planets is not suitable for ordinary people to live on; instead, they are suitable for special professions, like soldiers and explorers, to train and gain combat experience.
Everyone knows that F-series planets are very dangerous, and the Federation doesn't allow ordinary people and students to go there because these planets are too dangerous. Every year, there are reports of explorers who accidentally enter F-series planets and end up in accidents.
This has led the public to fearfully speculate about F-series planets, so when Shuangshuang mentioned that they might be going to an F-series planet this time, Chu Xinqiong and Liang Xuan's faces changed.
