"After pondering for a long time, unable to come up with any solutions, I realized my knowledge was too limited, my realm too low, and I couldn't even touch such a complex level... So, I decided to go to sleep."
"Coincidentally, I hadn't slept in a long time due to my research on bloodline runes, so I slept for seven days and seven nights, even getting the rare chance to dream."
"In my dream, I seemed to see an iron dragon with crossing wings, covered in rust!"
"There seemed to be many spots of light on the iron dragon's body, these spots flickered rhythmically and orderly... It was like the nodes of a wizard's spell model, and the spell runes that shimmered at these nodes!"
"At that moment, I suddenly had a bold idea. When I woke up, I recorded this idea."
