On this episode, Yona and the others attempt to dig out. Later, the princess did a second try to convince the Blue Dragon to join her.
The Blue Dragon turns out be really cool for a quiet character. Also I liked Yona is getting much better while being trapped. Other than that, it's quite unfortunate to see the villagers are still afraid of their Blue Dragon. Now how will the group find the next dragon? Overall, cool cave plot continuation.
Conclusion: Cool cave plot continuation.
