Chun Yu Zhongxiu said with a smile: "The art of combining vertical and horizontal began in the middle of the Warring States period, when the Wei State was weakened, and the three kingdoms of Qi, Chu, and Qin were the most powerful in the world, confronting each other and striving for the help of other countries in order to defeat each other. Although the other four kingdoms of Zhao, Wei, Han and Yan were weak, they were not vulnerable, and they were not to be outdone, and sometimes they confronted and sometimes united with the three kingdoms of Qi, Chu, and Qin. Therefore, there is the art of combining vertical and horizontal, Gongsun Yan lobbied the six eastern countries, united the countries and attacked Qin, it was for the purpose of combining vertical; After the death of Zhang Yi and Gongsun Yan, the Qin State became stronger, and the six countries in the East gradually weakened, so they often used to join the vertical and vertical against Qin, and successively there were Su Qin, Lu Zhonglian, and the four princes, although they were all vertical and horizontal families, but they all carried out the strategy of combining and vertical to resist the Qin State, and although the Qin State did not have such a vertical and horizontal family as Zhang Yi, it still used the plan created by Zhang Yi to break the vertical and longitudinal until now. ”

Gao Yuan nodded, and Chun Yu Zhongxiu's words generally explained the origin of the vertical and horizontal lines.

Later generations often think of Zhang Yi and Su Qin, and usually refer to these two people, as if these two people are the representatives of the vertical and horizontal, and they are also equal opponents.

But in fact, Zhang Yi and Su Qin are not from the same era, although the birth time of the two is unknown, but according to historical records, Su Qin died in 284 BC and Zhang Yi died in 310 BC, a difference of 26 years. Judging from the experiences of the two, Zhang Yi was mainly active during the reign of King Huiwen of Qin, that is, between 356 and 311 BC; And Su Qin's activity time was in the era of King Yan Zhao, that is, between 335 and 279 BC, which happened to be about 30 years apart, so Su Qin basically did not deal with Zhang Yi. And the person who is-for-tat with Zhang Yi and who created the strategy of cooperation is actually Gongsun Yan.

However, Gongsun Yan's luck seems to be bad, in the process of fighting with Zhang Yi, he has always been a bad move, and he is controlled everywhere, and his name in history is far less than Su Qin's, so there are some historical materials Zhang Guan Li Dai, and some of Gongsun Yan's deeds are placed on Su Qin, and the result gives people the impression that Su Qin is the founder of Hezong, and I don't know that there is Gongsun Yan.

In 318 BC, Gongsun Yan launched the first joint alliance, united the five kingdoms of Wei, Zhao, Han, Yan and Chu, and elected King Huai of Chu as the commander of the joint column to attack the Qin state. However, Zhang Yi lobbied for the division and alliance, so that Yan and Chu betrayed the alliance, and as a result, the five-nation alliance was defeated by Qin, and the first time to join forces to attack Qin, it ended in failure.

Subsequently, the six eastern countries successively organized four joint forces to attack Qin, namely:

In 298 BC, Meng Huijun and Han and Wei joined forces to attack Qin, but were defeated by Qin.

In 287 B.C., Su and Qin Pei joined forces with the six kingdoms of Qi, Wei, Zhao, Han, Yan and Chu to attack Qin, forcing King Qin Zhao to return part of the land of Zhao, Wei, Han, Chu and other countries he had captured, and did not dare to send another letter to Guguan for fifteen years. This was also the first victory of Hezong. And Su Qin is also famous all over the world, and he is respected with Zhang Yi.

In 247 B.C., Xinlingjun served as the general of Wei, formed a coalition army of Wei, Zhao, Han, Yan and Chu, defeated the Qin army, and took advantage of the victory to attack Hangu Pass, and the Qin army closed the gate tightly and did not dare to go out of the pass again.

In 241 BC, Pang Xuan, the general of Zhao, organized the five kingdoms of Wei, Zhao, Han, Chu, and Wei to join forces to attack Qin, but when they were in battle, Chu suddenly withdrew their troops, and as a result, the coalition army was defeated by Qin.

Of course, if the three countries succeed in forming a joint column this time, it will be the sixth joint column.

On the whole, regardless of the rescue of other countries, he took the initiative to attack the Qin State and formed a total of five times, and the ending was two wins and three defeats, and it was not advantageous, so Gao Yuan was not optimistic about the United Column, and it cannot be said that there was no reason.

But except for the last time, the first four mergers were organized by the recognized excellent columnists, and the result was two wins and two defeats, and Gao Yuan couldn't tell the reason for it for a while. If it is said that Xinlingjun organized the success of the alliance, it was because Xinlingjun was proficient in the art of war, but Su Qin was not famous for the art of war, not to mention that in the Qin State at that time, there was also a famous general Bai Qi in charge, but the alliance organized by Su Qin was also successful, so whether the main general was proficient in the art of war does not seem to be the decisive factor.

However, since Chun Yu Zhongxiu asked Gao Yuan like this, she naturally had her own promise, not only Gao Yuan was quite interested, but even Li Yinghong was very curious, although Li Yinghong did not like to deal with government affairs, but the combination of vertical and horizontal is not an ordinary government affairs, but includes many factors such as politics, economy, military, and diplomacy, so Li Yinghong does not exclude discussing the issue of vertical and horizontal cooperation.

Seeing that Gao Yuan and Li Yinghong were both looking at him, Chun Yu Zhongxiu said: "Actually, to put it bluntly, Hezong is to gather the weak and attack a strong, the six eastern countries are combined, naturally far stronger than Qin, as long as they can work together and unite, there is no reason to be invincible to Qin, so the victory of Hezong is because of the unity of all countries, and the defeat of Hezong is often the first internal split." ”

After listening to Chun Yu Zhongxiu's words, Gao Yuan thought thoughtfully, and Li Yinghong said: "Zhong Xiu's meaning, if you want to succeed in the alliance, you must first ask the countries of the alliance to unite, but how can we make the countries of the alliance united?" ”

Chun Yu Zhongxiu smiled and said: "Whether it is united or not, in fact, lies in the 'potential', if it is the general trend, all countries will be united, if the trend is not the trend, then even if there are such strange materials as Gongsun Yan and Meng Yujun, there is nothing to be done." ”

Li Yinghong still didn't understand it, and said: "So what is 'potential'? ”

But Gao Yuan understood Chunyu Zhongxiu's meaning, and said: "Zhong Xiu thinks that the general trend of merger and longitudinal has now become a success? ”

Chun Yu Zhongxiu smiled: "What does the husband think? Now that Han, Zhao, Wei, and Yan are all dead, and the Qin State is unstoppable, if it is not a general trend at this time, then when can it be regarded as a general trend? ”

Li Yinghong looked at the two of them and said, "You two don't want to be dumb, okay, can you tell me a little more detail." ”

Gao Yuan smiled and said: "Zhong Xiu's 'potential' means that all countries have to form a joint vertical shape, and only under this form will all countries put aside their selfishness and unite against the Qin State, which is where the success or failure of the joint vertical lies." ”

Chun Yu Zhongxiu said: "Gongsun Yan is also the material of Tianzhong, not under Zhang Yi, but although he pioneered the joint vertical, but at that time the Qin State was not the only strong in the world, the strength of Qi and Chu was not under the Qin State, and although the three Jin Dynasty were slightly inferior, they were not vulnerable, so at that time, the countries were not afraid of the Qin State, but just took the opportunity of the joint longitudinal to try to fish in troubled waters, naturally they could not work together, as long as the Qin State picked out the division, it was not difficult to break the joint vertical, Gongsun Yan's defeat was not that its material was inferior to Zhang Yi, but that it was not timely, At that time, the world failed to truly form a trend of unity. At that time, Qin and Qi stood side by side, and Qi only took advantage of the strength of the alliance to weaken Qin, but only Qi, Han, and Wei joined the three kingdoms of Qi, Han and Wei, and Qin also received the secret help of Zhao and Song, so Meng Weijun could only fail. ”

Li Yinghong nodded and said, "As soon as I say this, I understand, these two mergers failed, and sure enough, the trend of the combination did not succeed, so what about the later ones?" Didn't Su Qin form a successful merger? ”

Chun Yu Zhongxiu said: "Yes, although the alliance of the Su Qin organization was only eleven years later than Meng Yujun, but the general trend of the world at that time was very different, at that time, the Qin State took Bai Qi as the general, sent troops in Yique, attacked Han and Wei, captured 240,000 Korean troops, captured five cities, and captured the land east of Anyi in Korea to the Qianhe. He also broke the Wei army, captured the Wei general Gongsun Xi, and occupied sixty-one large and small cities. and forced the state of Chu to make peace, and the king of Chu Xiang even married a Qin woman as a wife to show his submission. For a while, the whole world was afraid of the Qin State, and at this time, Su Qin organized a merger, that is, the waterway canal was completed. Naturally, all countries should work together to resist the Qin State. ”

"As for the Xinling Jun's organization, it is the general trend, at that time the Qin State has won the victory of the Battle of Changping, although there is the defeat of Handan, but the national strength is still extremely strong, and the Zhao State is weak, there is no country in the world can fight against the Qin State, since the country is in danger, can only unite against the Qin State, so the Xinling Jun ascended to the heights, and naturally the followers are like clouds, and the result is that the combined column army defeated the Qin State, forcing the Qin State to retreat to Hangu Pass."

"And six years later, Pang Xuan once again organized a joint expedition against Qin, originally wanted to take advantage of the last Xinling Jun's great victory, and then defeated the Qin State, but the luck was not good, after the defeat of the Qin State in the last war, the threat to the countries has been greatly reduced, and there is no urgency, the countries can not unite and work together, not to mention Pang Xuan's talent and prestige can not be compared with the Xinling Jun, as a result, before the battle, the Chu army was frightened by the Qin army, and the remaining four countries are also each with their own ghosts, naturally not the opponent of the Qin State. Looking at the five combinations, they all became powerful and defeated because of lack of momentum. ”

Li Yinghong breathed a sigh of relief and said: "So that's the case, I said why some of them succeeded and some failed." It's still Zhong Xiu who is smart. ”

Gao Yuan also nodded frequently, Chun Yu Zhong Xiu's analysis of the successes and failures of the previous joint vertical and horizontal is indeed very well prepared, it can be seen that Chun Yu Zhong Xiu has indeed done a lot of hard work on the joint vertical and horizontal cooperation, in fact, the countries are not at the moment of crisis, when they have no choice but to form a joint vertical.

At this time, Chun Yu Zhongxiu said again: "Now the Qin State has destroyed the three kingdoms of Han, Zhao and Wei, almost occupying most of the world, and the trend of unification is almost unstoppable, fortunately, it is the rise of the husband, defeating the Qin army, and capturing the Yan State, which can be regarded as stopping the unification momentum of the Qin State, but although the Qin State has the defeat of the Yan Dynasty, the national strength is still far above Qi Chu, and the two countries of Qi and Chu are not without people of insight. The husband doesn't have to worry about Qi and Chu, and the two countries share different hearts. And the combat effectiveness of our army may not be under the Qin army, but there are few small people in the country, the strength is insufficient, it is difficult to compete with the Qin State for a long time, and the new Yan land is not yet stable, so it is a good time to organize a joint expedition against Qin, if the joint vertical is successful, we can wait for the opportunity to recover the old land of Zhao, expand the territory, and strengthen the strength. ”
