Those who read the novel knows that this is the start of everything

Spoiler
The other continent is the place that the dragon (i forgot her name) who help arthur live. The people there are actually preparing to have a huge war w/ the humans, elves & dwarf to conqure them & (some other thing i don't remember sorry). It was supposed to take a lot longer before the war start but coz the expedition team that boards the ship that arthur's invent got killed. They take the ship, learn how it operates & mass produce it to transport their soldiers to the human continent.
Other major spoiler (don't scroll down if you don't want to be spoil)
During the war, arthur decided to tell his parents the truth about himself..about his past life's memory etc & his parents can't accept the fact that their child is not really theirs but someone else (that's not true but that's how they felt). Arthur' dad died in the war & it happened when arthur & his parents relationship is not fully repaired yet which is extremely sad. Other things is that i began to hate the elf girl (i forgot her name too) coz she somehow become more immature as she grows. Plus, you are not gonna like their reunion trust me. Elijah is gonna get kidnap. The prof/principal is a spy. They dwarf king & queen is a spy (i don't remember whether they're a spy from the starts or they betrays the human & elves halfway in the war).

But i drooped the novel after chapter 200+ coz it kinda piss me off how....
Spoiler~~~
....Arthur has been training for a long time & not just once but many times already. He went through a lot & even trained by a dragon (not the one that saved him) but he still couldn't beat even a single general (one of the bad guy)...like it took him to give his all & his life to fight a general only for him to get his ass beaten & almost die every single time. Like come on author, when will the story progress if arthur can't even beat anyone. But this is just my opinion. Other people thinks it's okay.
The sneeze & the date part is soo cuuteeee!!! (≧∀≦)
