Description

刺耳的警报声穿透夜色,女孩从梦中惊醒。
沙尘包围了整片基地,风暴正激烈地敲打着门窗。女孩下意识想要呼喊母亲,又想起成年的拓荒者们都在基地之外执行探索任务。
一声巨响,临时居住区的屋顶出现了破损。
狰狞的黄色怪兽越来越近,女孩无处可逃,只能蜷缩在床角。一点银光从地底深处浮起,落在她脸颊上,像极了母亲的手。
女孩抱紧了妈妈留下的童话书。她记起母亲讲了一遍又一遍的故事,想从那些温柔的字句中汲取勇气。
狂风卷起一层又一层沙粒,那抹银光越发明显,化作了一条银色的缎带,轻轻托起了女孩。
她沉入了一段银色的梦境中。在这个清凉又温柔的梦里,她乘着月光飞了起来,风暴和怪兽都追不上她。
“......现在怎么样了?”
“身体指标正常。她受了一点惊吓,不过很快就能醒过来。”
“刚刚那异常的能量波动......”
“在最早的拓荒者留下的记载中,这些银色物质是一种名为‘递质’的特殊材料,由一名自愿加入拓荒队的科学家研发。拓荒者们习惯叫它‘银鞋子’,因为它常常帮助遇险的拓荒者回家。”
“那不是......这个开拓区刚刚建起来时候的事了吗?这么多年过去了,我还以为这只是个传说。”
“不,一定是真的。”病床上的女孩睁开了双眼,“妈妈......”
“妈妈在这里。”
“妈妈,‘银鞋子’的主人......去了哪里?”
母亲沉默了片刻,还是决定对女儿说实话。
“记载属实的话,她的确在这里生活过。但没有人知道她之后去了哪里。或许她是在一次深入探索任务中失踪了,又或许......她是自愿去了下一个和下下个更远的开拓区。”
女孩的眼睛里流露出瞬间的失落。但很快,她瞥见了床头的童话书,一下跳了起来,把书紧紧抱在怀里。
“我知道了,妈妈,她是不是和你送我的这本书里的主角一样?”
“那个......一直在旅途中的女孩?”
“是的,我最喜欢她了!”
“据说这本书的作者也是早期拓荒队成员,角色原型说不定......”
“是真的。”女孩的眼睛闪闪发亮,“她一定会和家人团聚,也一定能实现梦想。我也一样。”
