I am in love with this series. The main character is the type that will use every trick that isn't even writen in the book. C4 explosive he probably read it somewhere or he knows about it from his past life. Eururu i hope won't be exactly on front lines but help the wounded or make more explosives or other biochamical stuff(gas). I hope Yue emperor won't disapear for long for it seems has figured out that something wasn't right with empty castel and when to see for himself. well this is easier on the mind that most villains won't be fat dumb asses in the future.
