19 episodes in and i still don't understand what this show is about lol, are they just adventuring into old ruins, graves, etc looking for treasure? is there anything else?

I guess I wasn't alone. The first episode was so hilariously confusing, the mc breaks into someone's home and threw the young master into some wormhole or something. What I want to understand is how someone comes up with these stories and think its something people are going to like. These might be some of the reasons why donghuas aren't popular, though I prefer donghua over anime lol
