When the leader of a team is caught in a battle, the combat effectiveness will plummet, and some will even flee without a fight.

It can be seen how important a good general is, and the importance of the monarch to a country is self-evident, so every monarch will have the protection of a general around him, just like we play chess, you kill more enemies, the result is that your commander is eaten first and loses or you, but the monarch is often not the most able to take and fight, Liu Bei in the Three Kingdoms is often chased by the enemy army, several times are chased by the wife and abandoned the son, the heart is a little miserable, and even once almost captured by Lu Xunsheng, this is the famous Battle of Yiling, Therefore, the head of a country is not so easy.
Liu Bei launched a war against Eastern Wu, whether it was really Guan Yu or an attempt to swallow Wu under the guise of a righteous brother. In short, one thing is very certain, that is, Liu Bei failed miserably, and he lost in a mess. Under Lu Xun's fierce attack, Liu Bei desperately fled in a sea of fire, at this time he had no spare time to take care of the generals of the three armies, and if he hesitated a little, he might be buried in the sea of fire. Guan Xing and Zhang Bao fought desperately to protect Liu Bei from the enemy's blockade.
However, no matter how Zhang Bao and Guan Xing fought to the death, there was no way to repel the Wu army, but the situation became more and more dangerous, and finally both of them were injured. At this time, Liu Bei knew that his life was about to hang on the line, and it was very likely that he would die here. But just when he was desperate, Zhao Yun came with a team of people and horses to kill, and Zhao Yun's appearance was really timely, directly saving Liu Bei and turning the entire war situation around. As soon as Lu Xun saw that Zhao Yun had brought people to kill him, he immediately made a decision, abandoning the interception and killing of Liu Bei, and the whole army retreated. In this way, Liu Was saved without any danger.
Why was it that as soon as Zhao Yun got out of his horse, Lu Xun was so frightened that he quickly retreated, while Guan Xing and Zhang Bao resisted desperately but still could not protect Liu Bei's safety? This is really a problem, some people may say that although Guan Xing and Zhang Bao are the sons of Guan Yu and Zhang Fei, their force values cannot be compared with those of their fathers, and it is normal that they cannot defeat Lu Xun.
But to tell the truth, the strength of these two is not bad, although it is not as brave as their father's generation, but they can also be regarded as first-class fierce generals, with the appearance of Guan Yu Zhang Fei on their bodies, and their martial arts are not very bad. In fact, the reason why Zhao Yun was able to repel Lu Xun was only for the following reasons.
First,
Although Guan Xing and Zhang Bao were brave and fierce, they had been fighting with the Wu army for a long time, and they were already tired and tired, and their combat effectiveness at this time was not strong, and in the face of Lu Xun's deathly battle, there was no certainty of victory. Zhao Yun, on the other hand, was completely different, he had just been killed, his physical strength was still very strong, and his combat effectiveness at this time was the peak. Lu Xun was well aware of this truth, and if he still fought with it, it would not only be difficult to take advantage, but also suffer heavy casualties, so he resolutely chose to retreat.
Second
Zhao Yun's popularity is very large, and sometimes the battles between the two armies not only look at the combat effectiveness of the soldiers, but also look at the main generals. After years of conquest, Zhao Yun is already a well-known general, who has fought countless victories in his life, and is very good at marching and fighting.
Zhao Yun's appearance can be said to have strengthened the morale of the Shu army and frightened Lu Xun's army. Lu Xun was also suspicious of this, after all, Zhao Yun was famous and was still jealous of his appearance. This point, just like zhang fei Changbanpo drank and scared away Cao Jun, this is the advantage of the main general's fame.
Third,
Zhao Yun was indeed a strength bearer, and Lu Xun originally wanted to intercept and kill Liu Bei, but due to the appearance of Zhao Yun, Lu Xun knew that the probability of catching Liu Bei was extremely low. Because Zhao Yun's strength was even higher than Guan Xing and Zhang Bao's, he could be at the same level as Guan Yu. In the face of such a strong general, Lu Xun had no confidence to defeat. Therefore, it is better to preserve strength and take the initiative to retreat
