As Jinwoo continues his training, he completes a daily quest one day by doing more than the quest requires, and a key that leads to a certain item appears in front of him.
If I go into that castle right now, 
I'll definitely die. But...
...إن دخلت إلى تلك القلعة الآن، فسأموت بالتأكيد. لكن
Es wäre definitiv mein Tod,
wenn ich jetzt die Festung betreten würde.
Se eu entrasse no castelo
agora, morreria.
Если сунусь сейчас в замок,
то точно помру.
