Comics can be either trash or treasure. It all comes down to the quality of the story, the art style, and how well they connect with the reader. Good comics have the potential to be precious, while bad ones can be seen as trash.
The Treasure Hunting King was a web novel, and there was no manga version yet. However, if you want to read this novel, you can find an electronic version in the online library or read it online.
One lesson is about perspective. We should not be too quick to discard things as worthless. Just because we don't see the value in something doesn't mean it has no value at all. For example, in the story of the old chair, the neighbor didn't see any use for it, but the artist saw it as a blank canvas for his creativity.
Yes, it could be. If you like stories with a lot of character development, it might be right up your alley. Since it has this 'trash' element, it probably has a character or characters that transform in some way, which can be really interesting to follow.
One possible trash quote could be something overly melodramatic that doesn't add to the story's depth. For example, if a character in a mystery novel says, 'I just know something bad is going to happen, I can feel it in my bones!' without any real basis. It's just a filler line that doesn't contribute much to the plot or character development.
