Everyone's understanding of survival was still at the level of finding food to eat, water to drink, and a place to live. Therefore, they did not expect there to be so many tricks to survival, such as protein, vitamins, determining whether plants were poisonous, and so on.
If they did not look at this episode of Ye Chan and Ye Xuan's commentary, they would not have known that there was such knowledge involved. It was simply too professional. They were shocked and sent comments.
[Wow, these two are too professional! Why do I feel that they're even more professional than those survival experts?!]
[I think so too. Why did Baby Chan come to record the commentary for this show? Moreover, she's actually so good at commentating. She knows a little about all kinds of cold knowledge. I didn't even know that termites could be eaten. Moreover, the protein content is actually so high!]
