Cheng Zhijie, whose real name is Jinchi, is from Dong 'e, Jeju. When he was young, he was brave and good at hitting the target with one blow. At the end of the Sui Dynasty, the world was in chaos, and Cheng called hundreds of disciples to defend the village. Shi Biao started his army, and he went to take refuge and rode for the army. At that time, Shi Biao selected 8,000 brave soldiers who were different from ordinary people, with four generals in ancient times as the commander-in-chief, and Cheng was one of them. Shi Biao often tells people that "these 8,000 people can be a million-strong army". When Shi Mi was at war with Wang, Cheng led Ma Jun and Shi Mi to command the battle in the north of Mangshan Mountain. Wang Lingbing stormed Dan's foreign Ma Jun (Dan was also a famous hero in Sui and Tang Dynasties), and Shi Mi ordered Cheng and Pei Hangyan to support him. Pei Xingyan is also a brave rider. He rushed into the array first, was caught in the middle by the flow vector, and rolled down from his horse. Cheng stepped forward, mounted his horse first and killed the enemy. Wang's soldiers tried to behead the general before the battle and were invincible. Cheng got off the horse, put the seriously injured Pei Hangyan on the horse, and the two rode back. The king sent cavalry after him. Because Pei Hangyan was injured immediately, Cheng's movements were not as flexible as usual, and a root tip pierced his body (not a fatal place such as his chest). The hero gritted his teeth, turned around and broke the handle, pulled the soldier who was chasing him near, cut off his head with a knife and chased after him. No one dared to come near again, and finally the two returned to the camp safely. Pei is the prototype of the third hero in the Romance of Sui and Tang Dynasties. In the official history, he was brave and good at fighting, and was named "the enemy of ten thousand people." He fell to the queen, unwilling, and tried to assassinate him, but was killed by the king. )

Shi Biao and Wang fought hundreds of battles, with many victories and few defeats, but they were defeated in the battle of Luoshui. Cheng, Dan, Qin and others had to return to the king. This hero is a favorite of Emperor Yang Di and a semi-finalist of the Western Conference. He is "very generous" to these generals and hopes that they can help him destroy the world. Not long after getting along, Cheng said to Qin, "Wang Weiren is shallow and narrow-minded. He usually talks nonsense, likes to swear, and is superstitious about ghosts and gods. He is simply an old lady who jumps into the sky, and he is not a master of bringing order out of chaos! " Soon, Wang and Yu fought in Jiuqu, and Cheng and others were listed as war generals. Suddenly, they turned around with Qin and others and said to the king, "Thank you for your reception. I am eager to repay you. However, you are suspicious and there are many little people around you. I dare not stay with you for long. I hereby resign! " Say that finish, he took dozens of people around him and ran away to Tang Jun. Tens of thousands of soldiers and horses were behind the king, but because they were afraid of Cheng and others, they had to watch them leave, and no one dared to follow.

After returning to the Tang Dynasty, he became "invincible", followed the attack, captured Dou Jiande alive, surrendered to the king, and sealed lord protector House with military exploits. In the seventh year of Emperor Gaozu's Wude, Prince Li cut the left and right wings of the king of Qin, and transferred the course to Kangzhou Secretariat. In desperation, Wu Rencheng challenged him with words: "Your majesty's arm will be cut off today, and his body will soon be gone. I won't risk my life to leave. Please make up your mind quickly! " After the change of Xuanwu Gate, he was promoted to General Right Wuwei. During the Zhenguan period, Lu Guogong was one of the loyal ministers of Emperor Taizong from beginning to end.
