Yu Yixuan's mood is very complicated, although he has no intention of taking the imperial examination, but the heart of fame has not been extinguished, especially the heart of making friends with celebrities.

Even if Yu Guozhen attacked and killed the water thief, he still looked down on Yu Guozhen, because no matter how powerful Yu Guozhen was, he was just a white body, where could he compare to him.

But now, he has to look at Yu Guozhen with admiration, and he can even be said to admire him so much. Fang Yizhi Fang Mizhi, what kind of person is that, Tongcheng Fang is the Tianxia Sect, and Fang Yizhi is the leader of the younger generation, and his reputation is so loud, I don't know how many times higher than him, a man from the countryside!

How could his cousin make friends with such a person?

Yu Yixuan also wanted to visit Tongcheng, among his teachers and friends, quite a few had studied in the Fang family, but the door of the Fang family in Tongcheng was not so easy to enter, Yu Yixuan always asked himself, and felt that neither prestige nor knowledge was qualified.

But now, the most outstanding of the young generation of the Fang family has come to Xiang'an and their Yu family!

"Fifth uncle, this is Brother Fang of Fang Mi, and this is my uncle Yixuangong."

After Yu Guozhen and Fang Hezhi came out, they introduced the two to know each other, Yu Yixuan didn't dare to put an elder in front of Fang Yizhi, and preempted Fang Yizhi to give a salute: "The student's mentor Zi Chuan Gong once studied under the door of Wen Xiaogong, and the secret name is a great name, and the students have already ......heard of it."

"Wen Xiao" is the private word given by the doorman to Fang Yizhi's grandfather Fang Dazhen, and Yu Yixuan called it this way to show that he has a long relationship with the Fang family. He spoke very politely, but with a sour smell of a country scholar, he didn't have the appetite of Fang Yizhi, Fang Yizhi called himself a dragon sleeper, and he had always looked down on people who could only read dead books, so he just looked at Yu Guozhen's face.

After the three of them took their seats, Yu Yixuan was the oldest and was Yu Guozhen's elder, so Fang discussed two sentences of scripture with him with a wise and polite surname, and before Yu Yixuan could think about how to answer, he began to ask Yu Guozhen about natural subjects with great interest.

"These questions ......" Yu Yixuan listened to the two of them discuss the problem, and the more he listened, the more surprised he became, Fang had heard about it in the name of wisdom and erudition, but when did his nephew know so much miscellaneous learning?

From the seven colors of light, to the imaging of small holes, to the theory of the circle of the earth, most of what the two talked about, Yu Yixuan didn't understand much, but judging from the questions and answers, it turned out that Fang Yizhi was asking his cousin for advice.

Yu Yixuan's mouth gradually opened wide, looking at his nephew's expression, from surprise, to doubt, to numbness......

It is indeed numb, what Yu Guozhen has done recently surprised him, he can still pretend to be calm in front of his second brother Yu Yiqin, but now, he can't be calm at all.

Yu Guozhen and Fang Yizhi talked about encyclopedic knowledge all day, and it took a lot of energy to deal with Fang Yizhi, who was like a curious baby. In the afternoon, when Fang Yizhi proposed to leave, Yu Guozhen shook his head: "Brother Mi, I have some questions, and I still have to discuss with Brother Mi, why do I have to leave, could it be that the younger brother is not well entertained?" ”

"Where, where, what questions do you have, you are the one who solves my doubts today." Fang Yizhi said with a smile: "It's very interesting to think about the troublesome problem that makes Brother Guo Zhenxian, and I also ask Brother Guo Zhenxian to talk about it." ”

"Regarding the matter of dividing subjects, Brother Mi mentioned in the letter that he was writing the book "Physics Knowledge", and the younger brother was thinking that it seemed that it was still a little inaccurate to call natural knowledge in physics, and there were still places that could be subdivided. For example, the art of harvesting can be called agriculture, and the art of elixir can be called chemical ......"

Discipline classification is a very interesting thing for Fang Yizhi, when he wrote "Physics Knowledge" before, he listed some natural knowledge that he observed or learned, and the classification was very coarse, but now listening to Yu Guozhen's subdivision, he felt that his mouth was suddenly opened, and he couldn't help but praise it, and put forward his own opinions on how to classify it, so that after dinner, he saw that it was unwell and left again, so he could only stay in Xiang'an Town.

In the early morning of the second day, Fang Yizhi woke up, he finished washing, rode the horse prepared for him by the Yu family, and walked towards Yu Guozhen's yard without hurrying.

Out of the town, the originally muddy road was relatively easy to walk because of the gravel and coarse sand dragged in, and you could see farmers who got up early to work in the fields on the way. In the distance, a majestic slogan sounded, and Fang Yizhi's heart moved, this should be Yu Guozhen practicing his family.

He admires Wang Shouren, so he also likes military strategy, and occasionally dances with the servants at home with knives and guns, boasting of both civil and military skills. Regarding Yu Guozhen and less than twenty teenagers killing more water thieves than himself, Fang Yizhi admired it, but also had some doubts.

Then he saw a group of teenagers running in unison, dressed in the same color, and the leather-soled boots on their feet stepped on the coarse sand, making a popping sound, and the sound was very rhythmic. Most of the time, they pursed their lips and looked straight ahead, shouting slogans only after the teenager leading the group had opened his mouth.

Eighteen people are just that, but when they shout slogans, they seem to have the same momentum as hundreds of people. And these young men with a little immature faces, but their eyes are confident and firm, which Fang Yizhi did not see in the eyes of his family.

In fact, if he had come the day before yesterday, the eyes of these teenagers would not have been like this, but the battle with the water thieves the day before yesterday made these teenagers see blood at the same time, and also made them confident in their abilities.

Fang Yizhi stopped his horse and watched these teenagers run past him, they ran all the way to the entrance of the town, then turned around and ran back again. Fang Yizhi estimated that there were always more than seven miles of land back and forth.

When he arrived in front of the courtyard, Fang Yizhi did not rush in, but waited in front of the courtyard gate. Not long after, the teenagers ran back, although they were sweating profusely and panting, none of them were left behind, and even the formation was not scattered!

Fang Yizhi's eyes lit up, now the soldiers in the guard are unusable, he has also seen some elite soldiers of the general soldiers and generals, those who are known as the elite soldiers are brave, but when it comes to discipline and performance, they are only comparable to these teenagers!

"Brother Secret came so early." Entering the courtyard, Yu Guozhen was naked, rubbing his body with water, and his chest was rubbed red. Seeing the strong muscles on his body, Fang Yizhi looked down at himself with some shame, people in their twenties were not as strong as these fifteen or sixteen-year-old boys!

"Brother Guozhenxian, if you go to the border pass, I will definitely add another general!"

"Brother Secret praised."

"It's not a false praise, the elite pro-army I've seen is nothing more than that, maybe the Guanning Iron Cavalry will be stronger than you......"

"Guanning Iron Horse?" Yu Guozhen laughed disdainfully when he heard this word: "Brother Mi, don't mention those arrogant soldiers who have been defeated repeatedly." ”

"Do you mean to be disdainful?"

"The silver spent by the imperial court every year, even if it is smashed, is enough to bury the Tartars alive, the so-called Guanning Iron Cavalry has spent decades, what are the results besides wasting silver? Every year, I heard about the loss of land and heard the loss of soldiers...... That's it, let's not talk about this, Brother Mi also likes military affairs? ”

"That's nature, and the one I admire the most is Mr. Yang Ming."

Yu Guozhen took advantage of this reason to start discussing the military system with Fang Yizhi, and when they were halfway through the conversation, Yu Yixuan came to accompany him again, this time he was finally able to interject two sentences, but when he found that his little opinion was just a little skin in front of Yu Guozhen's military philosophy, he wisely chose to shut up.

Many of the various thoughts on ancient battles in the military history forum in later generations are deafening words in this life, and Yu Guozhen is good at speaking, and a day has passed in his endless talk.

"Brother Guo Zhenxian, I said it wrong in the morning, and I will compare you to the border general...... I really underestimate you, what you are talking about today, from the selection of troops, training, to the selection of generals, the use of generals, to the military formation, equipment, everything is involved, the grandson is reborn, Nantang is resurrected, but that's it! ”

"I'm just talking on paper, where do I deserve the praise of my secret brother...... Speaking of talking on paper, in fact, I have a different view on the Battle of Changping in private......"

"Oh, please advise Brother Guozhenxian."

"The younger brother thinks that the war has begun before the hand-to-hand battle, and what Sun Tzu said about 'temple calculation', I call it strategic ......"

"Strategy, I know, Gao Shi in the Tang Dynasty once gave poetry, 'There was no strategy at that time, this place is the border', Brother Guozhen is also proficient in poetry."

Yu Guozhen's face flushed slightly, he still thought that he was the first to propose the word "strategy", Fang Yizhi was worthy of erudition, and he found the origin of this word as soon as he opened his mouth. He didn't dwell on this, and continued: "At that time, in terms of the strategic situation, the Zhao State was more in urgent need of a quick battle, and the Qin State was not in a hurry, so Zhao Kuo came out of Changping, although he had his arrogant and arrogant side, but he had to come out. ”

"Oh, why did Brother Guo Zhenxian say that?"

"During the Battle of Changping, Qin had already gone through the Shang Dynasty to change the law, and annexed Bashu, built the Zhengguo Canal, the grain and millet output was the first in the world, and the foot of the armor was the same at that time, and the Zhao State was narrow and crowded, less plains and more mountainous areas, and the grain output was not as good as the Qin State, Lian Po held it in Changping for three years, and the Zhao State had been dragged to the exhaustion of national strength, and could not be delayed any longer, "Warring States Policy" contained, Zhao State asked Qi State for food, but Qi State did not support, and although Qin State has also been empty treasury, it is better than Zhao State. Therefore, Zhao State is more urgent than Qin State needs a quick war, and the King of Zhao uses Zhao Kuo to replace Lian Po, is it only because of the Qin people's counter-strategy, but also because Zhao State's national strength can no longer support Lian Po's old and serious military skills! ”

This point of view was something Fang Yizhi had never heard of before, and after thinking about it carefully, he slammed the table, which frightened Yu Yixuan: "That's right!" ”

"After Zhao Kuo replaced Lian Po, he naturally knew his lord's intentions, so he underestimated the enemy's advance, and caused the defeat of Changping, so the fundamental reason for Changping's defeat was not that Zhao Kuo talked about the army on paper, but that he had to underestimate the enemy's advance, so the crime did not lie in Zhao Kuo, but in King Zhao! The funny thing is that later generations laughed at Zhao Kuo for talking about the war on paper, but few people laughed at King Zhao, at most, they only explained to King Zhao that Zhao Kuo was dead, and he had to bear the charge for King Zhao. ”

Speaking of this, Yu Guozhen looked at Fang Yizhi deeply, Fang Yizhi was shocked, and the hand that was originally about to shoot the case again was slowly put down.

Where is this talking about the Battle of Changping, it is clearly a matter of this dynasty!
