This book is a very careful book of Nanyun, and it has been planned for a long time, but unfortunately the results are not ideal, perhaps it is a problem with the work itself, but despite this, Nanyun's reputation guarantees that he will continue to be more and less supervised, and finish this book carefully.

As long as there is a reader watching, Nagumo will continue to work hard until the end, thank you for your continued support.

Nanyun will continue to work hard, and strive to be more literate in the time outside of work, Nanyun thank you, thank you for taking time out of your busy schedule to read a few long-winded words from Nanyun.
