Are you headed back to Lung Shing Road in order to enter that contest?
You seem like a real busybody, but don't throw yourself into harm's way without the proper gear!
The taxidermist will give you a Corpse bottle if you speak with him.
You'll never capture the Three Corpses without one!
また行くのかい…
さっきはあわてて、びんを持たずに入ったんだろ？
三尸（サンシー）のびんは剥製屋がくれる。
びんがないと、三尸は捕まらないのさ。
I've been holdin' a contest, invitin' people to go capture some bad guys for me, but no one's succeeded yet.
Heehee... Would you care to scratch backs with a humble taxidermist?
I heard you did great work over on Lun' Shin' Road. Is that true?
If it is, then maybe... catchin' these bad guys will help with your fen' shui problem.
I'm tryin' to catch the Three Corpses. One, two, three out on Lun' Shin' Road.
Capture them all, and I'll give you my masterpiece, which is worth 500,000z!
Here's a Corpse Bottle. This one bottle can fit all three.
悪いやつを捕まえるコンテストをやったんだが、
成果がいまひとつでね、ひひひ、ひとつ、協力しあおうじゃないか。
龍城路ではずいぶん活躍したんだろ？どうだ？あんたは風水の問題を抱え込んでる。
俺は俺で、悪いやつらを捕まえてきてもらいたいんだ。
三尸（サンシー）さ。名前の通り３匹いてね。あそこのどこかに身を隠してる。
うまくいったら５０万紙紮の豪華剥製をやるよ。
これを持って行け。三尸のびん、こいつに３匹とも捕まえるんだ…。
Corpse Bottle acquired.
「三尸のびん」を入手しました。
To catch the Three Corpses, you'll need a certain bottle. I had a few, but the taxidermist bought them all up, hehe.
三尸のびんじゃないと捕まえられないんだ。そのびんは剥製屋が持って行ったんだよ、ふふふ、みんな持って行ったんだ…
Look who's back on Lung Shing Road! Tell me, did the taxidermist give you a Corpse bottle? Mind if I see it?
結局、あんたが来たのか。剥製屋から預かったんだな、三尸（サンシー）のびん。どれ、持ってるなら見せてくれ。
To catch the Three Corpses, you gotta use a bottle.
That whatchamacallit sword won't help you here. Nothing beats a good purpose-made bottle. Heheh.
三尸を捕まえるには、やっぱりびんだな。なんとかっていう刀じゃ無理だろうな…
三尸は三尸のびんに入れるのが一番なのさ…ふふふ、びんが一番さ。
I got the frame on! The malice mirror is ready to use. Just show it to anything you think looks suspicious. It'll suck up the malice right into the Corpse Bottle!
ようしできた。これで邪気を暴き出すことができる。怪しいと思う場所で、この鏡を使うんだ…それで邪気は三尸のびんに吸い込まれる。
