Figure 1 is an example of a JOP attack. In this example, the attacker's aim is to execute a system call "int 0x80" to open a new command line window. To do this, an attacker needs to modify the contents of the eax register to "0x0000000b" and the ebx register to the string "/bin/sh" before "int 0x80" is called, and the ecx and edx registers must point to the value "0x00000000". Suppose the value "0x0000000" and the string "/bin/sh" can be found in memory when the program is running. An attacker needs to construct the value "0x0000000b" himself. However, for the value "0x0000000b", when an attacker saves data to the stack through a buffer overflow, the "0x00" byte will trigger the system to terminate the read operation. This example specifically describes how the attacker uses the existing code snippet in the program to modify the value of val pushed into the stack by the attacker step by step from "0xffffff0b" to the value required by the system call "0x0000000b", thus implementing JOP attack. The following are the detailed steps of the process.　　令修缘顿悟自己的佛缘。新婚之夜，他抛下刚拜过堂的钱英，逃婚离家，得遇慧远禅师，受其洗礼佛心，诚心向佛，追随慧远来到灵隐寺，出家为僧，法号道济。自赖布衣（苗侨伟）以风水免去一身官职后，便与胡菁菁（黄造时）成亲，生活清闲安定。某日衣遇上张阳超（廖伟雄）和孔慈（庄静而）这对亦擅长风水卦象的师兄妹，慈对衣一见钟情，但因妒忌他的名气，于是两人由乡村斗至皇宫，各自施展绝招破解对方卦穴。。衣先拜得女北斗不过九（苏杏璇）为师，怎料却遭超戏弄，终被九逐出师门。后来衣无意中遇上南泰山凌林陆（谭炳文），并跟他钻研风水学说。 　　原来陆与九乃一对欢喜冤家，为争长短，两人订下由双方徒弟慈和衣来个风水大斗法。怎料慈和衣竟在斗法期间摆了大乌龙，闯下生死大祸……-Excerpt from the enthusiastic and explosive discussion of teammates after a pleasant team formation.Meemaw和Sturgis试图让Sheldon和另一个神童（Mckenna Grace）成为朋友，这让Sheldon惊慌失措。　　商人董大年曾遭遇土匪抢劫，得知刘和尚血洗马家，他与警察局联手，决心为民除害。
