It gets easier. My first language is hindi yet I am now able to read war and peace and bible kjv in a month. You get way faster after some time of doing this but your real way of speaking english doesn’t become as verbose which is my problem. Like you can understand difficult words easily after some time but you will still speak like americans not a victorian with elegance, which is something I wanted hence i started to read above mentioned books but sadly it seems the american anglo internet is what has shaped my english 😔
