Gan Luo is the grandson of Gan Mao, the minister of Qin, who has been smart since he was a child, and at a young age he worshiped under the Qin Prime Minister Lü Buwei and became his talented guest. Once Qin wanted to send an envoy to Yan, Lü Buwei asked the old minister Zhang Tang to answer the order, but repeated persuasions were ineffective. Gan Luo went to see Zhang Tang, analyzed the general trend of the world, listed the pros and cons, and said that Zhang Tang was impressed and ordered to make Yan. Lü Buwei praised Ganluo's talent. Soon after this incident, after Lü Buwei's recommendation, Gan Luo, as the envoy of the king of Qin, was ordered to go to Zhao and persuade Zhao Yan, the king of Zhao, to send troops to attack Yan. Later, Zhao sent the general Lian Po to attack Yan without fear, captured 36 cities in Shanggu, and gave 11 cities to Qin again according to the agreement. Ganluo made a miraculous achievement, and the Manchu Dynasty was shaken, and was named Shangqing (equivalent to the prime minister, located under the Xiangguo) by King Yingzheng of Qin, and gave him the confiscated field house of Ganmao. After serving as secretary for two years, Gan Luo contracted an illness and died after ineffective medical treatment. The folk deified Ganluo, and in the Dongting Lake area, many statues of Ganluo were erected. On the fifteenth day of the first month of every month, people bow and worship for the peace of the region; In these areas, when people encounter incurable diseases, they will ask the gods of Ganluo to appear and cure the disease, and they will take medicine to cure the disease or get clear guidance.

"Gan Luo sent an envoy to Zhao and became the prime minister at the age of twelve. This shows that Zhao Wang Zhao Yan is even more dim, but the most important thing at present is that Han and Wei have held the road to the east of Qin. It is better to take the opportunity to destroy South Korea first, and then try to Zhao and Wei. Meng Yi suggested.

"Okay, taking advantage of the scuffle between Zhao and Yan, I heard that Qi also wants to carve up the land of Yan, this scene is even better." King Yingzheng of Qin was very happy.

Over the years, the Qin State has continuously sent large armies to encroach on the border cities of the Three Jins, intending to further weaken the Three Jin and wait for the internal and external troubles of the Three Jin Dynasty to completely end the Three Jin Dynasty.

Wei Zeng, the new king of Wei, who had just succeeded to the throne, felt that Wei alone could not resist the Qin army, so he accepted the minister's suggestion, sent an envoy to Zhao, formed an alliance with it, and proposed to build a coalition army against Qin. In addition to Qi annexing Qin, Zhao, Han, Wei, Chu, Yan and other countries formed a coalition army, and jointly promoted Zhao to make Pang Xuan the commander and led the five-nation alliance to kill Qin. This was the Fifth Combined Attack on Qin.

The Battle of the Combined Attack on Qin refers to an operation in which Chu, Zhao, Wei, Han, Yan, Qi and other states successively formed various coalition armies to attack Qin between 318 BC and 241 BC. There are about 5 times. In the middle of the Warring States period, the two strong Qin and Qi confronted each other in the east and west, and the Qin army was the strongest. The Yellow River has almost become the Qinnei River. Qin Jin can attack, retreat can defend. The countries were seriously disturbed, so they planned to "join forces" to jointly control Qin.

The first three Qin troops won, as for the fourth battle of the joint attack on Qin, due to the high morality and outstanding talent of the commander Xinling Jun, the coalition army was victorious, but although the Qin state was defeated, its strength was not greatly damaged.

Therefore, although the coalition forces won the fourth battle against Qin, they did not seriously weaken the strength of the Qin army, nor did they stop the momentum of Qin's expansion.

Soon, in the face of the aggressive unification of the world by the Qin State, the princes of the countries that no longer existed as the co-lord of the world, Zhou Tianzi, smelled the cold air and bloody smell of the Qin army's sharp soldiers, united again and planned to launch the last joint attack on Qin during the Warring States Period.

In 241 B.C., led by the state of Chu and presided over by Huang Xie of Chunshenjun, the longitudinal movement began, in addition to Qi attached to Qin, Zhao, Han, Wei, Chu, Yan and other countries formed a coalition army, and jointly promoted Zhao to make Pang Xuan the commander and led the alliance of the five countries to kill the Qin state. This was the fifth battle of the joint attack on Qin, and it was also the last battle in history to attack Qin. Due to the weak foundation of Qin's newly occupied areas, the coalition forces achieved certain results at the beginning of the war, and the countries regained some lost territory.

"Veteran Pang Xuan, this person is not simple. As early as the time of King Wuling of Zhao, Pang Xuan once discussed with King Wuling, and explained the profound meaning of 'winning a hundred battles, and those who are not good are also good, and those who are good are also good without fighting'. Pang Nuan means to use medicine as a metaphor for politics, he believes that the superior doctor does not treat the disease, and prevention is better than cure, such as the prevention of the country before it happens; Medium-sized doctors treat minor illnesses and be cautious to prevent the disease from spreading and becoming serious, such as governing the country to prevent a thousand-mile embankment from collapsing in an anthill; Inferior doctors treat serious diseases, fill the mouth with fierce medicine, and scrape the bones, just like the chaotic times of governing the country with heavy canons, even if they can cure the disease, they also hurt the righteousness. Meng Yi kindly reminded King Yingzheng of Qin not to underestimate the enemy.

"As the saying goes: the veteran is out of the horse, a top two. It seems that Zhao will be difficult to conquer in a short period of time. King Qin was slightly worried.

"King, since the Battle of Changping, the national strength of Zhao has declined, and it has repeatedly fainted, and now it is holding on, but it is just relying on a few good generals." Meng Yi said sharply.

At this time, an urgent military situation came from the front: the forces of the Five Nations Coalition had captured several cities on the east bank of the Yellow River.

"With Hangu Pass, the Six Nations can only look at the Pass and sigh, and there is no need to worry." Qin Wang Yingzheng has experienced several crises since he was a child, and he has long stopped taking the six eastern countries in his eyes.

Meng Yi hesitated for a moment, and thought to himself: The last battle of the Six Eastern Kingdoms to attack Qin seemed to be quite smooth in the early stage, and they bypassed Hangu Pass and invaded Qin, should I remind King Yingzheng of Qin?

"Meng Yi, what are you thinking? Why is it so distressed? King Yingzheng of Qin was observant and asked loudly.

"King, what if the coalition forces make a detour to Pusaka and cross the Yellow River?" After an ideological struggle, Meng Yi decided to remind him that after all, it would not be long before the latest news came back from the front line, and it would not affect the direction of history.

"This ...... Is this possible? "King Yingzheng of Qin was taken aback, he had recently worked military strategy, and naturally understood what kind of impact the Five Nations Alliance would have if they crossed the Yellow River!

At this time, Admiral Meng Wei and Qin Xiang Lu Buwei asked to see each other at the same time.

"King, the latest military information is coming from the front line, the Five Nations Alliance Army is detouring to Pusaka and is building a pontoon bridge, and it will be able to enter the hinterland of Qin in a few days!" Admiral Meng Fu reported a shocking news.

"Your Majesty, gather your forces as quickly as possible. Xianyang is in danger! The State of Qin is in danger! Qin Xiang Lu Buwei was a little restless, and immediately spoke.

"Okay, this time, with Lu Xiangguo as the commander, and General Meng Fu as the assistant, we will definitely defeat the invading enemy!" King Yingzheng of Qin pretended to be calm and decided.

"What? The old man commands the army? Qin Xiang Lu Buwei thought that he had heard it wrong, and then he was in a trance for a while, and then accepted it ecstatically.

"The old minister obeys." The old general pondered for a moment, and also obediently accepted the order.

Only Meng Yi was silent, but Meng Yi thought: Qin Wang Yingzheng has really grown, and he quietly divided the military power into two, so that Lü Buwei and Meng Wei can contain each other to ensure that there will be no problems with the front-line army. As the saying goes, be prepared! After all, it was the first time that the Qin State encountered such a crisis, and it actually allowed the coalition army to invade the hinterland, so it was difficult to guarantee that no one would have different intentions?

Pang Xuan, commander of the Five-Nation Alliance, believed that the division attacking Qin had repeatedly attacked westward, but they were all blocked at Hangu Pass, so it was better to take Pusaka by detour, cross the Yellow River in the south, and take it by surprise after making a detour to Hangu Pass. The alliance of the five nations went out of Pusaka by different routes, progressed smoothly, entered the hinterland of Qin, and met the Qin army led by Lü Buwei when they reached Yucheng.

The news spread all over the world, and the eyes of people all over the world gathered in the small city. The coalition army totaled 500,000 horses, and the Qin State also gathered 500,000 horses, and the number of both sides was about the same. However, the coalition army invaded the hinterland of Qin for the first time, and morale was inevitably high. And the Qin army lost the city and lost the land, and actually let the enemy army almost break into the territory of Xianyang, and naturally people were panicked.

Yucheng is located eighty miles east of Xianyang, just north of Lishan in the Qinling Mountains.

"The coalition forces were invincible all the way, and successively captured Pusaka, Luoyin, Wucheng, and Tongcheng. Now we must not retreat again, otherwise the enemy army will descend on Xianyang City! The veteran general gave a brief introduction to the military situation and expressed his opinion, as calm as ever.

"The coalition forces have come from afar, and it is difficult to transport logistical grain, grass, weapons, and baggage. The old man had already ordered the fortified walls to clear the wilderness, but fortunately, the local organization was tight, and the enemy army could not get a large amount of supplies in the territory of Qin. Qin Xiang Lu Buwei also introduced the local government affairs and put forward his own suggestions, "One word: drag!" The coalition forces were too exhausted to divide their forces to capture the surplus cities. As long as we hold back the enemy army and do not fight a decisive battle with it, the coalition forces will collapse without a fight. ”

"Yes, the strength of the two sides is about the same, and the gap between morale and equipment is not big, so we must not fight to the death!" Wang Jian is the new spokesperson of the Wang family, and he also echoed it.

Sun Tzu said: The first army is to fight, the second is to attack the enemy, the second is to attack the army, and then the next is to attack the city. Why don't we send some troops to harass the enemy's logistics and transportation lines first? "The old general Meng Fu has experienced a hundred battles, so naturally he will not defend the city to the death.

"Okay, send half of the cavalry to harass the enemy's logistics and transportation lines." Qin Xiang Lu Buwei made a decisive decision.

"Now that you've set a strategy, how do you implement it?" The old general stroked his beard and said.

"I think the biggest advantage of the cavalry is mobility, and the attack power is not as good as the chariot soldiers for the time being, so it is better to leave it to the cavalry generals to decide for themselves, how about it?" General Wang Jian made a suggestion.

"Well, this is exactly what the old man wants. Sun Tzu said: The shape of the soldier is like water, the shape of the water avoids the height and tends to the bottom, and the shape of the soldier avoids the real and hits the void. General Meng Fu agreed.

"Well, according to your words." After all, Qin Xiang Lu Buwei was inferior to a general with rich experience in actual combat in terms of tactical planning, so he naturally readily agreed.

The sky was bright and bright, and Meng Yi, Meng Tian, Wang Ben, Li Xin, and Zhang Han each led 3,000 cavalry to prepare for a sneak attack on the logistics and transportation lines of the coalition army.

"Meng Yi, you have the most ghost ideas, tell me, how are you going to fight?"

"There are not a few enemy cavalry, and I heard that Zhao also sent elite cavalry from the north to resist the Xiongnu, which is the iron-blooded cavalry trained by the cavalry general Li Mu. We must not fight hard! Meng Yi thought for a while and analyzed.
