y　son…in…law　placed　these　boulders　here　as　you　see　them；　and　he　said　they　represented　the　Eight…Array　Maze。　They　are　like　eight　doors；　and　according　to　the　scheme　are　named：　Gate　of　Rest；　Gate　of　Life；　Gate　of　Injury；　Gate　of　Obstruction；　Gate　of　Prospect；　Gate　of　Death；　Gate　of　Surprise；　and　Gate　of　Openings。

〃They　are　capable　of　infinite　mutations　and　would　be　equal　to　a　hundred　thousand　soldiers。　As　he　was　leaving；　he　told　me　that　if　any　leader　of　Wu　became　mazed　in　them；　I　was　not　to　conduct　him　outside。　From　a　precipice　near　by　I　saw　you；　General；　enter　in　at　the　Gate　of　Death。　As　I　guessed　you　were　ignorant　of　the　scheme；　I　knew　you　would　be　entangled。　But　I　am　of　a　good　disposition　and　could　not　bear　that　you　should　be　entrapped　without　possibility　of　escape；　so　I　came　to　guide　you　to　the　Gate　of　Life。〃

Lu　Xun　took　his　way　to　his　camp　in　deep　thought。

〃This　Zhuge　Liang　is　well　named　Sleeping　Dragon；〃　said　he。　〃I　am　not　his　equal。〃

Then；　to　the　amazement　of　all；　Lu　Xun　gave　orders　to　retire。　The　officers　ventured　to　remonstrate；　seeing　that　they　had　been　so　successful。

〃General；　you　have　utterly　broken　the　enemy；　and　Liu　Bei　is　shut　up　in　one　small　city。　It　seems　the　time　to　smite；　and　yet　you　retire　because　you　have　e　across　a　mysterious　arrangeme
