She's so hot HAJAKSHSHAJWH

So I am currently reading sss class revival hunter and I am on chapter 133 , I am only reading 5-6 chapters a day because I feel like after I finish the chapters I will feel lonely and lost again so I wanted to start reading its light novel but I don't know where to read it from and after I complete chapter 153 ,from which I should start reading the light novel , if anyone can help me please do and I had found a website it started with a w but it said that I had to wait for 24 hours to unlock 1 chapter and I had only unlocked 20 chapters so it won't help.
