I Am a Sewer Sword Immortal

The ancients never lied to me. Who would have thought you could transmigrate through a sewer?

I can't do anything, yet people think I'm some kind of demon or heretic? Fine, but why do so many troubles keep coming my way? Could it be because of the sin I committed that day when I saw someone bathing?

(The beginning might be a little rough, but stick with it and I don't think you'll be disappointed. QAQ)

P.S. This book is a slow burn, and a little angsty.
