You have to pay to see other chapters. You also might need to make an account
if you use the app it only works on the lezhin comics plus app or just use the website and make an account ^^
I went on the website and I am able to see it but when I go on the app it won't let me it just shows me the introduction, I also have an account
Lezhin on app store/googleplay store doesn't have POTN series it's only introduction same like other manhwa you should go to lezhin website and download the app through the website.
Check your purchases list. It should be there.
The problem is that I want to read this on lezhin but every time I search it up in the search box it only shows me the introduction.
