Okay kiddo, so a webserial is kind of like a storybook that someone writes on the internet. Instead of putting all the story in one big book, they break it up into smaller chunks called "episodes" or "chapters."
So, let's say someone wants to write a story about a superhero. They might write one episode about how the superhero got their powers, another episode about how they saved somebody from danger, and so on.
The cool thing about webserials is that they can be updated really easily. The writer can add new episodes whenever they want, and you can read them whenever you want too.
Sometimes, people also add pictures or videos to their webserials to make them even more exciting. And the best part? You can read them for free!
