强行修改PUSH 0a -----> push 10 运行下发现还是没有改成16
只能继续跟下去了返回到上级函数

01001DD8 |. E8 849F0000 call 0100BD61
01001DDD |. 85C0 test eax, eax
进入100675b
其中发现了个很熟悉的函数
010067BD |. 56 push esi
010067BE |. E8 63FEFFFF call 01006626 ;在这里
这个时候我们进入01006626单击右键查看调用树发现就两个地方（前面分析的那个函数和这个函数）
这个时候可以肯定修改了上个push 0a就没问题了。。。。(第一次出错的时候就该查看下调用栈 看看有没有再调用这个函数的地方)
爆破 复制可执行文件....
成功~~~
其实只修改第二个就可以达到爆破的目的
