‘少主，主公信上说了什么？’庞德对着马超问道。
‘父亲在信中说，计划有变，欲将曹操大军引致渭水，让我等十日之后前往埋伏，里应外合一举歼灭曹军，诛杀曹操本人！’马超说道。
话音刚落，韩遂在一名文士的陪同之下来到了马超面前。
‘叔父你看，父亲这是何意？’马超将书信交予韩遂后问道。
韩遂拿着书信反反复复看了多遍，疑惑的对着一旁的文士说道：‘成公军师你看，确实是大哥的字迹，可是大哥明明已经下达了命令，为何此时又改变计划呢？’此人复姓成公，单名英，是韩遂的心腹军师。
‘少将军，送信之人呢？可看清来人。’成公英问道。‘是末将接的信，此人已经走了，说是若不及时赶回，恐曹操发现，此人身穿我军军服，并且也是我凉州口音，应该是主公带去的人没错了。’庞德说道。
‘那便奇怪了，在下认为还是谨慎为好。’成公英说道。
‘如此看来，这定是父亲想到了更好的办法，我等按照父亲所说去做便是！’马超道。
‘此事还需谨慎，不若我们在伏兵之后再安置一支队伍负责接应，以备万全，但愿我是杞人忧天吧········’成公英说道。

‘众将听令！’曹操喝道。
‘许褚为先锋，引军一万，全部换做西凉军服！我亲提五万中军随后！曹仁！引军一万由渭水之南而行，于禁！引军一万由渭水之北而行！尔等切记隐蔽行迹！待我大军中伏，你二人由南北杀出，聚歼敌军！’曹操道。
‘诺！’
‘奉孝，此次你就不用一同前往了，你的身体恐受不了西凉苦寒之地，你就安心回许昌修养。’曹操关切的说道。
‘主公，郭嘉无碍，请主公务必带我前去！’郭嘉道。
‘此次文和会随我同去，有文和在足矣，你安心静养身体，日后天下平定还要依仗奉孝！好了！不用再说了！’曹操拒绝道。
‘遵命！’郭嘉只好答应道。‘奉孝，你此次回许昌，传令荀彧督建“中原学府”同时广布天下，一年之后举办学府大考！此外，面向天下招纳学子，我们要在中原地区打造出一个不亚于扬州书院的学府！’
‘遵命！敢问主公何时归来。’郭嘉问道。‘少则三月，多则半年！我定踏平凉州！’曹操霸气的说道。

建业龙昱府邸。
‘主公，探马来报，曹操与马腾于五日前已从长安出兵，往西凉而去，先后大约十万余人。’陈宫道。
‘难道马超真的反了？还是说马腾这只是诱敌之计·········’龙昱疑惑着自言自语道。
‘主公您说什么？’陈宫问道。‘噢，没什么，传令我们在西凉的人，一定密切监视马腾府邸，如有变动，立刻行动！’‘遵命！’
天水议事厅。
韩遂坐于主位之上，目视下方说道：‘探马来报，大哥他们已经出兵前往渭水而去，我们也应该行动了！’
‘叔父，我这便带人前去布置埋伏，接应父亲！哼！曹操狗贼，这次我们父子二人定叫你有来无回！’马超厉声道。
马超离去之后，成公英起身说道：‘庞德将军，你引两万人于少将军后十里外跟随，若无事便随少将军一同杀敌，若有变故，立即接应少将军撤回！’‘诺！’庞德接令离开。
‘军师，你认为大哥已经遭遇不测了吗···········’韩遂问道。‘但愿是我多虑了··········’成公英担忧的说道。

‘少将军！哨骑探报，三十里外发现主公部队与曹军，我西凉将士为前军，曹军为后。’
‘哼！狡猾的曹贼！
