花似雪坐在电脑前面，左手端着一杯咖啡，右手正在电脑上写代码，十分悠哉。到现在花似雪已经将ACGO的黄色题目刷了有1/4了，目前正在与另一道黄题做着纠缠。 “又是DP……”花似雪露出了不屑的表情，拔出长剑，又拿出DP模块装载在上面，迎着飞来的黄题一连打出五朵剑花。于是，又一道题死于非命，转眼变成了经验值被花似雪吸入体内。 花似雪将长剑收入鞘内，一屁股坐在一处小丘上，看着下面那些和入门题占了个旗鼓相当，甚至有些力不从心的那些新手们，花似雪不仅苦笑起来。 “ACGO才开服一会儿，没什么高手来很正常。”花似雪这样安慰自己，转头准备去到比赛场地时，突然发现下面有另一位侠客，手持长刃，身前有一群黄题和橙题，正虎视眈眈地盯着那位。只见他一跃而起，在空中突然一个回撤，打出一招燕返斩。顿时，那些黄题橙题顿时被收割于脚下。’ “好生厉害的剑法！”花似雪不禁一惊，在他来这里后从未见过对剑法掌握如此娴熟的程序员。此时，对方正用毛笔在纸上写这些题的做法。写罢，他便召来一只青鹤，将纸系在青鹤的腿上，然后便让鹤飞走了。在这个世界，这个过程叫做：“提交题解” “少侠，你……”花似雪正准备开口，那人便化作千万灵光，传送而去了。 “刚刚那位是谁？怎么如此厉害？”花似雪的心仿佛被扔入鹅卵石的湖面，开始不断颤动，但后来花似雪想通了，便扑哧一声哈哈大笑了起来，“哈哈哈哈哈哈！原来，之前的我是那么自负啊！这世上，还真不只我一个人会如此高深的剑术啊！”笑罢，花似雪恢复了冷静，站在山头之上，重新注视着那远方又一个新的领域。那是绿色领域，官方名称叫做“普及+/提高领域”，花似雪不知道后面会多难，但他听说，这世上的题目总共有红，黄，橙，绿，蓝，紫，黑七种领域，每种领域的题目又会得到史诗级加强。而那些被题目击败的人，虽然会无限重生，但是也会受到很大的打击。 “好，那么，下一站，绿色！”花似雪从山丘上轻灵一跃，朝着远方绿色的领域走去。 走了一段路之后，花似雪明显感觉到前方的灵力波动突然加强，一个不留神，巨大的灵力直接将他向后打出好几米。好不容易稳住身形，花似雪抬头一看，前方便是绿色领域与橙色领域的交界处。 “可恶，绿色已经加强那么多了吗？”花似雪这样想着，心里涌起了一阵无奈。他便想到了一开始自己从红色区域升级到黄色区域的时候，直接被巨大的灵力波动弹了回去。现在他的修为固然强大了不少，但是绿色领域的灵力强度也不甘示弱啊。 花似雪直起身子，运足十二分灵力，抬腿向前走去，十几米后，一道绿色的，高的不见顶的墙壁出现在花似雪的眼前。定了定神，花似雪发现城墙的下面有一道门，门口由两个橙色题目和一个绿色题目守着。这些怪物一见到花似雪，便如饿虎见绵羊一般扑了过来。但可惜花似雪不是绵羊，一个转身躲开了两道橙色题目，随即拔出长剑，向着两个橙色题目刺去。顿时间，两个团子就爆开来，化为了万千灵力。 花似雪一转头，瞧见后面的绿色题目正不紧不慢的蠕动过来。花似雪打开题面分析了一下，不仅暗笑：“哈哈，一道模拟想难住我？”顿时拔出长剑，一招举火烧天，朝绿色题目刺了过去，但没想到的是，绿色题目顿时变形，粘液性的身体变成了一只大手，死死捏住了花似雪的长剑。 “怎么？不是模拟？”花似雪不禁一惊，但还没等他细想，长剑连同花似雪顿时被一阵强大的灵力爆破炸出老远，重重落在地上。 绿色的怪物又回归了本来的团子模样，朝着花似雪蠕动而来，花似雪此时已经全身无力，站不起来了。望着慢慢蠕动来的绿色怪物，花似雪不禁暗笑道：“好了，都结束了……”
