About some of the details and the setting of the level of technology in this book

First of all, I would like to thank all the book friends for your support, this is my first time writing a book, although I will do my best to write, but there will inevitably be some shortcomings. Therefore, I hope that all of you can give me advice, point out my shortcomings, and help me improve.

Because it was the first time I wrote a book, in order to be lazy and not to mislead a book friend, I set this novel as an alternate history class, because I was afraid that my shallowness would disappoint you.

However, the author hereby assures you that the general setting of this book is still the history of the Tianbao period, and the author will try to consult relevant materials to restore a relatively real history of the Tang Dynasty, especially about the general trend of the court, and all the famous civil ministers and military generals in history will appear relatively close to history one by one.

Especially in the label of the Anshi Rebellion, the author will put more effort into restoring this turmoil that changed the course of Chinese history, explaining its causes, processes and important impacts. To ensure the general authenticity, it also allows book lovers to learn some historical knowledge when they are easy to read.

Then there is the question of the place of birth, because the author is writing a book for the first time, in order to facilitate going to the provincial library to consult the local county records, so it has to be set in the author's hometown, and I hope that all book friends can forgive.

As for Wang Bo's matter, it is really helpless, although there are many famous places in Yuzhang, such as "Yuzhang Ten Scenes" and other scenic spots, but most of them are in the Ming and Qing dynasties, the early Tang Dynasty, and the Wude period, because of the construction of Yuzhang New City, the original "Guancheng" It has been dilapidated, some of the buildings of the Han Dynasty in the past have almost been destroyed in the years, and the attractions of the new city have not yet been formed, so I have to change the fate of Wang Bo, so that this famous text can give the protagonist some help, so I hope that all the students who like Wang Bo will not be surprised, of course, Wang Bo's descendants must not come to me to defend their rights!! woo......

Finally, there are some settings about the level of science and technology in this book, because the protagonist came to this world, there are now martial arts masters, and there will be some more awesome hidden masters in the future, these people may go on the opposite side of the protagonist, in order to add some means to the protagonist, so the level of science and technology at that time has been improved, of course, it will not be too nonsense, the approximate level of science and technology will be set at the level of the two Song Dynasty, because the age is not very far apart, and the development of science and technology in ancient times is slow, under certain conditions, it is also possible to achieve。

Therefore, I would like to ask all of you to be merciful to your strict book friends, and I hope that you will forgive me when there are some things that are beyond the times in the book!

Finally, thank you again for coming, the author will do his best to write this book!

Thank you!
