For fun's sake!

New mission received by my brother:

Find out what 危険 and 地雷原means.

Time limit: 7 days

Last resort: Ask Japanese teacher (don't wanna do that)

Yosh! Here I go!

Update:

Time used: 15 minutes

危険 (きけん) Danger

地雷原 (じらいげん) Minefield

So... Danger minefield? What the hell is my brother up to?
