"The virtuous nephew performed quite well in all aspects during the last martial arts, and he is indeed a rare talent, but you are still young, some things cannot be handled independently, and you are in the filial piety period, so why don't you wait a few more years, wait for a little older, and then recommend it for you, isn't it better?" Pei Xingjian looked at Liu Yidao silently.

"Pei Shilang is right, but I want to avenge my father earlier, be ashamed of my Tang Dynasty, and fulfill the righteousness of filial piety, so I want to join the army earlier and give full play to my strengths, so that I can lead the troops to fight earlier. Liu Yi already knew that his idea of obtaining an official position by virtue of his status as the first name of Wuju was basically impossible to realize, and the imperial court would definitely not award him the title winner of Wuju who was filial piety due to his father's death, but only by other methods, such as getting a strong recommendation from Pei Xingjian.

"That's right!" Pei Xingjian nodded, "It's just that you grew up in the mansion since you were a child, and your mother doesn't want your brothers to practice martial arts, and your father rarely talks about the three of you brothers about military affairs, even if you join the army and want to lead the troops to fight, it's not so simple..."

Although it is said that when Pei Xingjian asked some things about the art of war and strategy during the martial arts competition, thinking that Liu Yi is young and has never been on the battlefield, it is impossible to be better than ordinary people in terms of how to use soldiers.

"In the next skill, I dare not say that I can win the world, but I feel that it should not be bad, as for the art of war and strategy, I really haven't studied it systematically, only some of my own ideas!" Liu Yi said very sincerely. The identity of the agent in later generations also belongs to the military establishment, coupled with Liu Yi's sense of war since he was a child, and many famous battles in later generations, including modern and modern times, have also been studied a lot, especially the Mongol expedition back then, and the strategy adopted by the German mustache in World War II, which is highly respected by Liu Yi.

Hearing Liu Yi say it so bluntly, Pei Xingjian was also more interested, thought for a while, and asked with a solemn look, "Then tell me, what are the reasons for your father's defeat this time?" ”

"This..." Liu Yi didn't expect Pei Xingjian to ask this without scruples, and he didn't know how to answer all of a sudden.

Pei Xingjian ignored Liu Yi's surprised appearance, and said eloquently: "Back then, his mentor Xing Guogong went out to conquer the Western Turks, and led an army of 10,000 to be besieged by more than 100,000 people of Ashina Helu, and the final result was --- that the Turks were defeated, and Ashina Helu only led a few hundred horsemen to escape!" Next, he used 7,000 people to deal with the 100,000 enemies of the Tibetans, but in the end, the Tibetans only returned 5,000 people..."

Liu Yi was shocked when he heard this, although he knew that Su Dingfang was a famous general, but he didn't expect it to be so brave, and he won many victories with weak troops many times, and his record was so brilliant.

"At that time, Shizu Weiguo Gong led an army of 3,000 and took advantage of the heavy snow to directly attack Jieli's 100,000 army, but Jieli's soldiers were defeated and fled; The enshi only led 200 soldiers to attack Jieli's tent in the fog, and the tens of thousands of remnants led by Jieli were defeated again and finally captured; Later, the teacher went to the northwest with Cheng Zhijie, and the teacher faced the Turkic army of tens of thousands with 500 horsemen, and the result was... The Turkic army was defeated, and the mentor led his troops to run nearly a hundred miles and kill thousands of people..."Pei Xingjian said with a proud face.

"Ahh Liu Yi was even more surprised when he heard it, is this Su Dingfang a human or a god? Several battles have been heavy losses to several times the enemy with weak troops, it seems that Li Jing's disciples have extraordinary abilities, including Li Jing, Su Dingfang, and Pei Xingjian in front of them, their military exploits can really be used to brag for a lifetime.

"Weak troops are not terrible, as long as they plan properly, they can still win the battle..."Pei Xingjian put away his smugness and said without any expression.

Liu Yi also understood Pei Xingjian's intention in saying these things, then his father did not improvise due to the situation on the battlefield, if he could make a contingency, he would not have been defeated so badly, and the whole army would have been wiped out.

"I know that in the first battle of Qinghai, my father was defeated, and I have an unshirkable responsibility," Liu Yi had already thought about this during the period of guarding the tomb, but no one blamed his father, and he didn't bother to think about anything more, but now Pei Xingjian, who was more serious, asked, and he had to say some thoughts, "I didn't make random responses, and I didn't effectively detect the movements of the Tubo army..."

"Go on!" Pei Xingjian breathed a sigh of relief in his heart, hearing that he secretly accused Liu Xianli, the son of Liu Xianli in front of him was not angry, and he analyzed it seriously, and he became more interested.

"On the march, the movement of the enemy army is the most important thing to find out, the army led by my father, when I encountered the Tubo people, I thought it was a small Tubo army, and did not make a response, until I was surrounded by the Tubo people, I realized that it was surrounded by hundreds of thousands of Tubo troops, which also shows that the previous intelligence work was not done well, the movements of the Tubo people were not mastered, and the natural and geographical advantages were not well used!" Liu Yi was a person with special achievements in later generations, and he had a natural sensitivity to intelligence, and he also knew that intelligence was very important during the battle, if he could find the enemy first and make a response, he should be able to grasp the initiative in the battle and launch a surprise attack on the enemy.

"If it were you, how would you respond?" Pei Xingjian asked quietly.

"The number of sergeants is not the only factor that determines the success or failure of the war, when fighting with the enemy, you can use a flexible and mobile way, a rapid assault, a speed to win, go straight to the enemy's leader, capture the thief and capture the king, so that the dragon is leaderless, and then break the enemy, so as to finally win the war!" Liu Yi said almost without thinking, "The army's mobile ability and attack speed, as well as the intelligence detectives, are the key to victory in most cases, and my father did not pay enough attention to these aspects, and did not give full play to the rapid mobility of the cavalry he led, so that he was surrounded by the Tubos..."

After Liu Yi got the general situation of the battle of Qinghai, he also made an analysis, and he also understood that the defeat of this battle was also related to his father's missteps in tactics, and his father relied too much on the support of the 150,000 troops behind.

Liu Yi also thought that even if Li Jingxuan's reinforcements arrived later, hundreds of thousands of troops would face each other, and the battle situation would be very tragic, and the losses of the side would be very heavy, and it was still unknown whether they could win.

In exchange for the greatest victory at the smallest price, this is the first thing that generals should consider when fighting, as Pei Xingjian said just now, those famous battles commanded by Li Jing and Su Dingfang were all taken this way.

If my father could put aside the psychological sustenance of this 150,000-strong army, with only 30,000 horses, and carry out a rapid attack on the Tubo people when they were defenseless, the result might have been completely different.

"Hmm! It is very reasonable," Pei Xingjian said with praise on his face when he heard this, "It's just that things on the battlefield won't be so simple, your father is also a battle-hardened general, and he will definitely make improvisational measures!" There are other very important factors that are the reason for the defeat of our army..."

"Pei Shilang is saying that Tubo's Treatise on Qinling is also a general who is good at using soldiers?" Liu Yi thought for a moment and asked.

"Exactly!" The taste of appreciation on Pei Xingjian's face became stronger, "This is an opponent that we should not underestimate!"

"Pei Shilang knows this person very well!" Liu Yi also asked with great interest.

"I don't know much, just because I don't understand, so there are a lot of things that I don't know," Pei Xingjian shook his head and said, as if he suddenly thought of something, "I want to go to the palace once today, he said that if I am free, I want to discuss the process of this war with you, you go back first, what you said, I will seriously think about it..."
