All Hail Lelouch! All Hail Britannia!

To the stars and beyond. Here i am again. With an interesting puzzle idea. This time i will test your hearing skills. There is a giveaway code in that audio file. The voice is mine and i am reading a script that i wrote. All the things i say and the quotes i use are just for the script. You will find a hidden message somewhere. That's the key to open a CHESS GAME Just joking. All the instructions to solve the puzzle are hidden inside the file. I hope you can hear well.

Some notes:

1. The prizes are trash games. If you are here to only get some free games this puzzle is not for you. But if you still want to solve it, that would make me happy.
2. We tried to talk as slow and understandable as we can for not English speakers. We can't speak too :D You don't know how many times we tried but i believe everyone can understand.
3. I made the voice record with my brother and sister. Biggest thanks go to them.
4. There are some mispronunciations and grammar mistakes. İmminiman tried to help me to fix but i couldn't record it again.
5. You can listen to it without fear there are no bad words used, no screaming etc.
6. If you listened several times but couldn't understand you can use a sound to text app. That's okay to me.

Hints: I really worked hard for this puzzle. Would like to see more people to try this.

1. They are books. Listen carefully i used exact word by word quotations for every book. My siblings reading those parts.
2. You need to find the names of the books and take their first letters all lower case.
3. I saw someone was having issue about autocorrect or something. When you find the code make sure to double check!
4. For the second part think like you can't hear but you need to hear.
5. I already made it. So, here it is Japanese version
