Is there a novel?

Yes there is as it said so in https://www.anime-planet.com/manga/how-to-survive-as-a-dragon-with-time-limit-novel
But unfortunately I don’t know a website that has this novel

I could only found the raw of the novel: https://booktoki328.com/novel/7084811?stx=%EC%8B%9C%ED%95%9C%EB%B6%80+%EB%93%9C%EB%9E%98%EA%B3%A4%EC%9D%98
Chapter 17 of the manhwa is around chapter 22 or 23 of the novel.
