掛了电话没两分钟，“乐评人老k”的微博就更新了。
他发了一条长文，標题是给姜云的命题作文。
《打工人的辛酸与梦想
正文里写著：“姜云，你不是住城中村吗？不是说自己接地气吗？”
“那你就写一首关於打工人的歌，要是写不出底层的真实感，就別再装模作样！”
这条微博一发布，立刻被网友转发到了直播间。
观眾们都看出来了，老k这是故意刁难，暗讽姜云没经歷过底层生活，写不出真实的打工人状態。
“老k也太坏了吧！这题目明显就是针对姜云！”
“打工人的辛酸哪有那么好写？得真的体验过才行！”
“姜云老师能写出来吗？有点担心。”
直播间里议论纷纷，连主持人冰冰都忍不住替姜云捏了把汗。
“姜老师，老k定的这个题目，您有把握吗？”
姜云看著屏幕上的题目，心里却平静得很。
老k不知道，他穿越到这个世界后，住了一年的城中村，做过的兼职两只手都数不过来。
快餐店收银、外卖员、工地搬砖、印刷厂打包……
这些经歷，都是最真实的打工人生活。
他站起身，走到那张不足一平米的小书桌前，从抽屉里拿出一张废纸。
这是昨天用剩下的纸，背面还能写字。
姜云把纸铺平，拿起那支旧原子笔，指尖在纸上顿了两秒，脑海里已经开始筛选“中华小曲库”里的歌曲。
很快，一首熟悉的旋律浮现在他的脑海里。
《追梦赤子心
这首歌里的“不妥协直到变老”“生命的闪耀不坚持到底怎能看到”，不正是打工人在辛酸中坚持梦想的真实写照吗？
姜云低下头，笔尖在纸上快速移动，发出“沙沙”的声响。
摄像机把镜头拉近，观眾们能清晰地看到，纸上的歌词和简谱一行行浮现出来。
“充满鲜的世界到底在哪里”
如果它真的存在那么我一定会去”
我想在那里最高的山峰矗立”
不在乎它是不是悬崖峭壁……”
第一段主歌刚写出来，直播间的弹幕就安静了不少。
之前还担心的观眾，此刻都被歌词吸引了。
“这歌词……也太真实了吧？像极了我刚毕业时的样子。”
“不在乎它是不是悬崖峭壁』，这不就是打工人的倔强吗？”
“姜云老师肯定经歷过，不然写不出这种感觉！”
姜云没有停笔，继续写著副歌部分。
他的笔速很快，字跡却依旧工整，简谱的高低音標註也清清楚楚。
摄像师的镜头扫过书桌角落，无意间拍到了放在那里的“姜云希望小学”纪念证书。
红色的封皮在一堆废纸里格外显眼。
