@marsbars Nah, he froze/transformed in ice the magic blade spell thingie that was piercing the princess chen so he could stop/destroy it and stop the princess to absorb the magic. He said already that this fact is top secret.
Also, i'm not a doctor, but i'm pretty sure that a 5 year old pierced from part to part in the chest area with a 1 hand sword like blade doesn't need anyone help to die in a matter of seconds.
As for the death of a 5 year old, i guess the chinese autor, and the man behind this assassination doesn't dick around : D
