Yes, it can be used by other characters, meaning other humans can use this method. Though, Arin doesn't know what completely happens after using this method, but he knows that it works. Thanks for your support!! I really appreciate!!
Yeah!! We'll definitely know about these in the chapters to come.
As for the premium part, I shifted it to next month, like towards the end of next month. If possible, I would have loved to continue without going premium, but in order for the novel to grow, I have to go premium. It can't be avoided. All the same, you're one of the reasons why this novel is good, I really appreciate that. Thank you for all your support, and I hope you keep reading and enjoying this novel.
I originally planned to go premium before the end of this month, but after much observation, I decided to move it to next month. So, this book will go premium at least on the 21st of next month. Thanks for reading!!
