可以考虑将重复的代码提取为函数，减少代码冗余。同时，可以将一些常量进行定义，以提高代码可读性和可维护性。以下是优化后的代码：

local MP_XINGSU = 9
local MP_XIAOYAO = 10

local function joinMenpai(sceneId, selfId, targetId, mpInfo, xinfaLevels)
    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

    LuaFnJoinMenpai(sceneId, selfId, targetId, mpInfo[2])

    for i, level in ipairs(xinfaLevels) do
        LuaFnSetXinFaLevel(sceneId, selfId, level, 30)
    end

    LuaFnSendSpecificImpactToUnit(sceneId, selfId, selfId, selfId, 148, 0)

    local name = LuaFnGetName(sceneId, selfId)
    BroadMsgByChatPipe(sceneId, selfId, "#cFF0000[门派公告]:#c66ccff["..name.."]#P已经加入了"..mpInfo[1].."！", 4)

    x990010_ooo(sceneId, selfId)
    CallScriptFunction(999994, "ActionSkill", sceneId, selfId, -1)
end

if arg == 101 then
    joinMenpai(sceneId, selfId, targetId, x990010_g_mpInfo[arg-101], {31, 32, 33, 34, 35, 36})
end

if arg == 102 then
    joinMenpai(sceneId, selfId, targetId, x990010_g_mpInfo[arg-101], {49, 50, 51, 52, 53, 54})
end
