I was watching a YouTube video where the main character (MC) finds a female dragon in a cave.
Before she dies, she gives the MC her egg. Later, the story unfolds: he encounters other humanoid races like Asuras and the dragon race. He discovers that the female dragon he met was a princess of the Dragon Kingdom and heir to the throne.
Now, her daughter is the rightful heir. He leaves her (the princess) with her grandfather, the King of the Dragon Kingdom, who appears to be in human form.
Interestingly, her granddaughter, who was initially in dragon form, can now transform into a human. The MC departs because he has other obligations.
I had added this video to a YouTube playlist, but it seems to be deleted or hidden, and I can't find it anymore.
Can anyone identify this manhwa/manhua? Based on the art style, I believe it's more likely a manhwa.
