seen　vapors　rising　from　the　boulders；　they　seemed　to　e　from　inside　them。〃

Lu　Xun　decided　to　go　and　look　at　these　boulders　himself。　So　he　rode　off；　with　a　small　escort。　Looked　down　from　a　declivity；　the　stones　were　evidently　arranged　with　a　design　related　to　the　eight　points　of　the　pass。　There　were　doors　and　door…sills　and　lintels。

〃This　looks　likely　to　drive　a　person　out　of　his　senses；〃　he　said。　〃I　wonder　whether　it　is　any　good。〃

They　rode　down　with　intent　to　examine　the　mysterious　arrangement　more　closely　and　went　in　among　the　stones。

Presently　one　of　the　escort　called　attention　to　the　increasing　darkness　and　said；　〃The　sun　is　setting。　We　ought　to　be　returning　to　camp。〃

But　as　Lu　Xun　glanced　round　to　look　for　an　exit；　a　sudden　squall　came　on　and　the　dust　whirled　up；　obscuring　both　sky　and　earth。　And　in　the　swirl　the　stones　reared　themselves　up　like　steep　mountains；　pointed　like　swords；　and　the　dust　and　sand　shaped　themselves　into　waves　and　hillocks　one　behind　the　other。　The　roar　of　the　boiling　river　was　as　the　drums　before　a　battle。

〃This　is　some　trick　of　Zhuge　Liang；〃　said　Lu　Xun　in　a　scared　voice；　〃and　I　have　been　caught。〃

He　would　go　out；　but　he　had　quite　lost　his　way　and　could　find　no　exit。　As　he　stopped　to　consider　what　he　should　do；　an　old　man　suddenly　appeared。

The　old　man　said；　〃Does　the　General　wish　to　go　out？〃

〃I　greatly　desire　that　you　would　pilot　me　out；　O　Elder！〃　replied　he。

Leaning　on　his　staff；　the　old　man　led　the　way　and　with　quiet　dignity　conducted　Lu　Xun　outside。　He　had　no　difficulty　in　finding　his　way　and　paused　not　a　single　instant。　When　they　were　once　again　on　the　slope；　Lu　Xun　asked　his　aged　guide　who　he　was。

〃I　am　Zhuge　Liang's　father…in…law。　My　name　is　Huang　Chenyan。　M
