可以考虑将重复的代码提取出来，避免代码冗余和重复编写。具体可以将 arg 值作为参数传入一个函数中，然后根据不同的 arg 值执行不同的操作。示例代码如下：

local function joinMenpai(sceneId, selfId, targetId, arg)
    if GetMenPai(sceneId, selfId) ~= 9 then
        x990010_MsgBox(sceneId, selfId, targetId, "你已是别的门派的高徒了，我们不收你。")
        return
    end
    
    local xinfaInfo = {}
    if arg == 103 then
        xinfaInfo = {1, 2, 3, 4, 5, 6}
        LuaFnJoinMenpai(sceneId, selfId, targetId, MP_SHAOLIN)
    elseif arg == 104 then
        xinfaInfo = {43, 44, 45, 46, 47, 48}
        LuaFnJoinMenpai(sceneId, selfId, targetId, MP_TIANSHAN)
    end
    
    for i, xinfaId in ipairs(xinfaInfo) do
        LuaFnSetXinFaLevel(sceneId, selfId, xinfaId, 30)
    end
    
    LuaFnSendSpecificImpactToUnit(sceneId, selfId, selfId, selfId, 148, 0)
    local nam = LuaFnGetName(sceneId, selfId)
    BroadMsgByChatPipe(sceneId, selfId, "#cFF0000[门派公告]:#c66ccff["..nam.."]#P已经加入了"..x990010_g_mpInfo[arg-101][1].."！", 4)
    CallScriptFunction(999994, "ActionSkill", sceneId, selfId, -1)
    x990010_ooo(sceneId, selfId)
end

if arg == 103 or arg == 104 then
    joinMenpai(sceneId, selfId, targetId, arg)
end

这样可以有效减少代码量，使代码更加简洁易读。
