Woopread is currently translating the novel, but they haven't caught up to the part where the manhwa is at, so it won't be anything new ( https://woopread.com/series/ill-retire-after-saving-the-world).
If you're fine with raws, you could go to Ridibooks to directly buy chapters or rent one chapter per day for free (search 세상만 구하고 은퇴하겠습니다 ridibooks). Or you could go to Booktoki, which has free raw chapters up to 342. If you want, I could send you the link privately.
Thank you!!
Anyone knows where I can read the light novel?
