Purestream, water treatment specialist, is working hard as always, cautious and conscientious.
She always thought that throwing coins into water to make a wish was a rather silly practice.

Description

我的护身符丢了,找了很久都没找到。虽然只是在炎国执行任务时顺道买的小玩意,但据当地人说,是在寺庙里开过光的。有人告诉我,可以去清流那儿问问看。清流......我对这个名字没有太深的印象,难道是后勤部负责失物招领的新干员?
不在宿舍......
也不在会议室......
我是在大浴场找到的她,她刚结束检修工作,当时正在——泡澡,我在门外甚至能听到她在唱歌,高音很完美......只是泡那么久不会难受吗?
“抱歉抱歉,让你久等了。”
“罗德岛的排污工作是合格的,但对于过滤系统本身的清洁未免也太不重视了,绝大多数区域都有积淤,需要频繁进出,我只能等到全部清理工作完成才......嘿嘿。”
“你看看这是你的护身符吗?”
这位小姑娘一边自顾自地说着,一边打开一个袋子,除了我的护身符,我还看到里面有弹珠、发卡、试管,甚至一个弹夹......
“这些,都是在排污过滤系统里找到的?”
“是啊。刚发现的时候裹了一层泥巴,很脏,但我已经认真清洗过了。”
我刚想问“为什么会丢到那儿去”,但忍住了,这个问题似乎该问我自己......
后来我和工程部的朋友聊起这次本舰故障检修,谁也没想到问题居然出在排污系统上,刚入职一天的清流干员独立承担了清理任务,在脏兮兮的内过滤系统里待了足足两天......个别区域堵塞的“罪魁祸首”,便是我们这些意外丢失遍寻不见的“宝贝”。我想起我此前表示感谢时清流有些羞怯的笑容,她只是叮嘱说“以后请注意”,顺便交代了一些注意事项。水能够冲走一切,所以我们习惯了扭扭龙头按按开关,很简单。也正是因为水能够冲走一切,所以我们从来不知道,看不见的地方,有多污浊。
听说清流已经负责起了罗德岛的舰船排污工作,我不知道她喜欢什么,想来想去,只好买了块香皂送给她,后来才知道她已经收到很多块了。看来不止我一个人想到向她表示感谢。

——摘自清流入职定期评估时某干员的叙述
