<h2>武鸣人一号滑动</h2>
<div class="content"><p>当时明月在,曾照彩云归<br /><br />
倦了红颜，憔悴为千年，几多情深夜语，一点听风悠然。<br />
村忆梦回，飘逸如烟，友别怜影单。<br />
而今沙漠风闲，雪原清冷，东海云淡，石谷谁惜缘。<br />
累了心间，问也还烦，都道风沙淘尽，何日再慰别缘！ </p></div>
</li>
<li>
<h2>武鸣人二号滑动</h2>
<div class="content"><p>立剑赏月意惆怅,袖饰刀,衣披霜,傲视雾丸,徒手战扶桑.<br />
问津终寻帝王陵,黑影没,尸满岗,惟见逆鲮露寒光. <br />
须发苍,气轩昂,三尺银狼武鸣人,破风动八方. <br />
依身紧握噬魂枪,饮虎血,豪万丈.惟有千年我故乡!</p></div>
</li>
<li>
<h2>武鸣人三号滑动</h2>
<div class="content"><p>曾经有个梦想：驰骋江湖，快意恩仇。<br />
曾经有份愿望：千里追凶，十步溅血。<br />
曾经有腔豪情：奇功盖世，名冠武林。<br />
曾经有种期盼：烛影摇红，衣袖添香。</p></div>
</li>
<li>
<h2>武鸣人四号滑动</h2>
<div class="content"><p>赵客缦胡缨，吴钩霜雪明。银鞍照白马，飒沓如流星。 <br />
十步杀一人，千里不留行。事了拂衣去，深藏身与名。 <br />
闲过信陵饮，脱剑膝前横。将炙啖朱亥，持觞劝侯嬴。 <br />
三杯吐然诺，五岳倒为轻。眼花耳热后，意气素霓生。 <br />
救赵挥金锤，邯郸先震惊。千秋二壮士，烜赫大梁城。 <br />
纵死侠骨香，不惭世上英。谁能书阁下，白首太玄经。</p>
</div>
</li>
<li>
<h2>武鸣人五号滑动</h2>
<div class="content"><p>素手相牵，斜辉入眼帘，一轮逍遥自在间，醉了山水闲。<br />
沙漠绿水涟，鱼游浅底，明眸一水天。<br />
爱在村友相谈，开心点点，笑语连连，率性夜无眠。<br />
月在西边，风乱星寒，辗转醇香旧事，蛾儿曼舞灯前。</p></div>
</li>
<li>
<h2>武鸣人六号滑动</h2>
<div class="content"><p>蹄影善奔,如幻如魔,其皮传世,绝学再现,<br />
又有谁在这残阳道中追逐它的身影... </p>
</div>
</li>
</ul>
