I think the answer to that is buried somewhere in this thread. If im remembering it even vaguely correctly, Emperor, Empress and IC Yun all retire to MC and ML's country/territory. orz Hopefully, some brave soul will go through this thread sometime and compile all of the spoilers into a master post with every answer.
well, if we're told Persian Blade forging then we'll thinkin of Damascus steel forging. and MC's military dagger is a top quality steel i suppose. just, is the dagger also made of damascus forging or japanese style forging?
When the MC is pregnant, how did the ML treated her? And when the twins are born, how does the ML treated them? I am really curious
Well, the persian eccentric is just a cover story so it's likely a modern knife. Those can be made of a variety of different spring steel and/or stainless steel alloys and made in a number of ways. A-Heng describes the iron essence swords as 'It was nothing more than low-quality steel with low carbon content'. Low carbon content means they cant be properly hardened or heat treated. So any which way your flip it, she could probably easily break, in some way or another, those "prided" swords with her knife. All she'd have to do is hit the sword at the right angle/point and the sword would break.
I just finished reading all the spoilers and I realized that there was something that bothered me. What happened to the fiancée or wife of the third prince, since he married Chen Yu. He did not succeed in killing her after all the trouble our MC has given to heal he, right?
