Hi readers. I'm deeply sorry for not updating for so long. As of the moment, I still plan to revise all the chapters of my books before I update new chapters. As you noticed, there are tons of grammatical errors. I've written my books 3 years ago and I have like, a little knowledge about writing back then so now, I plan to make it more interesting to read. Thank you for bearing with me. Please continue to support HPCDAM and IETAV.
