S4 saw a rise in viewership, but S5 remained pretty much the same. Viewership did not drop by much as there were still many interesting events occurring on planet Baiji and a lot of news.
Every time Fang Zhao followed people from the outpost team to assist with construction, some thrilling or exciting scene was captured—the weird creatures and plants of planet Baiji that could be both dangerous and violent.
Also, sometimes Fang Zhao followed the outpost team and completed more dangerous tasks that were not convenient for Kevin Lin to follow. Thus, in these cases, Kevin Lin headed to the military district and did some interviews to help the masses understand the thoughts of the pioneer immigrants. This aroused the curiosity of the many viewers as well.
