No is not
I think you need to learn first what code means, for example:
this is what a switch is:
https://msdn.microsoft.com/en-us/library/06tc147t.aspx
Then... in the game, the player makes request to server like this way:
switch (PlayerRequest)
{
case RequestCharList:
{ code to run };
break;
case RequestCharCreation:
{ code to run };
break;
.
.
.
.
.
case RequestMasterDisciple: <---------------this is the one you need to find
{
................ if(player.lvl <=60) --------> CMP xxx,3C <----------this is what you need to change if you want to change the lvl requirement, otherwhise, change the jumps.
}
