Under the desperate resistance of the Qin army behind the palace, Meng Yi finally entered the Qinling Mountains with the remaining four thousand tired divisions.

"If we want to get rid of the entanglement of Zhao Guo's iron cavalry, we can take advantage of the dangerous terrain of Huashan. Then turn to Hangu Pass. Meng Yi took the map made by the Qin State Soldiers and analyzed the situation of the enemy and us.

"To Hangu Pass? That's a good idea. We are not afraid that the enemy will cut us off. Meng Tian looked at the map and agreed.

"The key is whether we can block the pursuit of Zhao Guotie's cavalry in Huashan." Meng Yi calmed down and thought about it.

Huashan was called "Xiyue" in ancient times, and was called "Taihua Mountain", which is one of the famous five mountains in China, the birthplace of Chinese civilization, and the "Hua" of "China" and "Huaxia" originated from Huashan. Connecting the Qinling Mountains in the south and overlooking the Huangwei Mountains in the north, there has been a saying of "the first mountain in the world of strange dangers" since ancient times.

Mount Hua is 30 miles long from east to west, 20 miles wide from north to south, and there are five dangerous peaks.

Meng Yi took the uninjured soldiers first, cutting down trees and digging rocks.

When they reach dangerous intersections and canyons, they block the intersections with earth and rocks and pile up trees. When the rest of the palace passes, they will block the intersection and set fire to it.

"There is a shortage of water in the mountains, and the pursuers can only sigh at the fire. When the fire was extinguished and the earth and rocks were extremely hot, they had no choice but to do so for the time being. By the time they clear the way, we've gone far. Meng Yi could finally breathe a sigh of relief.

"Since ancient times, Huashan has a road. Unless they take a long detour, but we've blocked all the canyons here, and they can do it! Meng Tian finally relaxed his sadness.

"What about our casualties?" Although Meng Yi knew that there was definitely no good news, he couldn't help but ask.

"Our army has 6,000 men, and now there are only 3,000 left, including thousands of wounded soldiers." Meng Tian sighed and said with a wry smile.

"It's not too bad. At least half of the soldiers were withdrawn. It was so dangerous just now that I almost got the whole army into it! Meng Yi comforted, "Pass the order, eat dry food, spring water, and continue to move forward!" ”

The peaks of Huashan are majestic, and the mountain roads are rugged and difficult to walk.

"Since ancient times, Huashan has a road. The grain and grass are gone, and the Qin army that sneaked up on them has also run away, why is the sky so unfair! Pang Xuan, the commander of the coalition forces, couldn't help but smile bitterly, and now even he didn't know how to explain to the five-nation coalition forces.

The valley is full of lush bamboo forests and pines and cypresses, and the mountain flowers are also blowing in the spring breeze, and a clear stream is flowing beside the road. Turning around a small bamboo forest, everyone saw a wide waterfall smashing down from the top of the cliff tens of meters high with the momentum of flying thousands of miles, causing splashes of water. Suddenly, the rumbling sound of water came endlessly. Underneath the waterfall is a huge waterhole with a radius of 100 meters. The ponds, flowers, and woods complement each other, and even birds and birds and small beasts are also haunted, and the harmonious and natural beauty suddenly makes Meng Yi and others refreshed.

"Finally escaped, let the soldiers hunt and fish, eat a full meal, and then bathe and rest. The 10-day mountain trail is really bone-chilling. Meng Yi breathed a sigh of relief, and finally sat down on the ground.

"Damn, this Pang Xuan is really ruthless, he chased him for three days and three nights before he was willing to give up!" Meng Tian scolded fiercely.

"He was afraid that we would go back and sneak attack the logistics and transportation of the coalition forces, so he simply drove us away. I can guarantee that there must be no less than 30,000 cavalry guarding the logistics and transportation line on the line from Yucheng to Pusaka. Meng Yi was so hungry that he analyzed while nibbling on the little dry food he had left.

"I see, I wonder why there is at least a day's difference between the two armies, and they are still chasing after them." Meng Tian suddenly realized, and then he became worried again, "But our dry food is almost finished, there are still five days of mountain road from Hangu Pass, can thousands of soldiers hold it?" ”

"There is no way, I can only let the soldiers hunt more prey along the way, and if it doesn't work, kill the horses!" Meng Yi smiled bitterly.

"Kill the horse? This is not good, horses are the hearts and souls of the cavalry, how can they kill horses? As soon as Meng Tian heard this, he immediately refused to agree.

"Is human life more important or is it important to horses? It's all this time, don't say it's a heart and liver baby, even if it's the king of heaven, you have to bite twice! Meng Yi suddenly understood that this brother in history was forced to commit suicide by an edict from Qin II, which shows that this person does not know how to be flexible: even if he is unwilling to rebel, he will always flee in disguise. What's more, there are tens of thousands of miles in the Saibei grassland, where does the Qin army go to find you?

"This ...... Well, I'll go give orders. Meng Tian was distressed for a long time before he figured it out.

In this way, the two brothers Meng Yi retreated to Hangu Pass with 3,000 remnants.

The Guanzhong Plain is between the Qinling Mountains and the North Mountains of Weibei (Laolongshan, Sagashan, Yaowang Mountain, Yaoshan, Huanglongshan, Liangshan, etc.), starting from Baoji in the west, reaching Tongguan in the east, narrow in the west and wide in the east, known as "Qinchuan for eight hundred miles".

The name of Guanzhong began in the Warring States Period, because there is Dasanguan in the west, Hangu Pass in the east, Wuguan in the south, and Xiaoguan in the north, so it is taken from the four passes (Tongguan in the east and two golden locks in the north were added later). The passes of the Quartet, coupled with the two natural barriers of the Northern Shaanxi Plateau and the Qinling Mountains, have made Guanzhong a battleground for soldiers since ancient times. During the Warring States Period, the Wei State established Shang County in the lower reaches of the Luo River, and the Chu State established Hanzhong County in the middle reaches of the Han River. After the unification of Qin, the world was divided into 36 counties. The northern part of Guanzhong is the upper county, and the governance is located in Fushi; Southern Shaanxi is Hanzhong County, and the seat of governance is in Nanzheng; The Wei River basin is located in the internal history and is in charge of the Kisuke area near Kyoto.

In 246 BC, due to the fear of Qin, Korea sent Zheng Guo, a hydraulic engineer, into Qin to offer suggestions for repairing canals, so as to consume Qin's manpower and resources and weaken Qin's army. This move backfired and made the Qin state stronger. Zheng Guo Quze irrigated more than 40,000 hectares of land, with a yield of 200 catties per mu, so Guanzhong was fertile, no murderous years, Qin was rich and strong, and died and princes.

Without further ado, let's get down to business.

The Qin State fought in the Guanzhong Plain, and had an advantage in all aspects such as grain and grass materials, weapons and soldiers, while the grain and grass of the Five Nations Alliance Army were not only convenient for transportation in Zhao, Wei and Han, but Yan Chu was miserable.

At this time, the logistics and transportation lines of the coalition forces were tight, and the commander Pang Xuan decided to storm Yucheng.

"Ladies and gentlemen, we have a month's worth of food and grass, and we must not delay it for a long time in Yucheng. Yucheng is only eighty miles away from Xianyang! As long as we work hard, we will definitely be able to return the Qin State to the Rongdi era! Commander Pang Xuan pretended to be full of confidence, hoping to impress all countries to fight bravely.

"You Zhao Guotie cavalry can't even protect the grain and grass, how can we attack the city with all our strength with peace of mind?" Xiong Wu, the general of the State of Chu, angrily accused. At the same time, he was indeed dissatisfied with Sanjin in his heart, because the Chu State was far away from the Qin State and the labor expedition, and the Sanjin actually shirked its own limited grain and grass stocks and could not help friendly troops. Sanjin is really a cheat.

"Siege? The Qin army is as numerous as us, how can it be attacked? South Korean General Han Ping said hesitantly. Although he was also very excited, after all, this was the first time that South Korea had invaded the hinterland of Qin, and it was spread out that there was a lot of face. The whole of Korea will be proud of him. But there are fewer Korean soldiers, and if one dies, there will be one less. After returning to China, how did he explain to King Han?

"I think it's better to retreat, anyway, Sanjin has also recovered a lot of cities. And I haven't reaped the slightest benefit from Yan Kingdom. Su Cheng, the general of the Yan State, said complainingly. In fact, the Yan State was afraid that after the Qin State weakened, the Sanjin Dynasty became strong again. In particular, Zhao State is the greatest threat to Yan State, and Yan State is eager to carve up Zhao State with Qin State, which can not only strengthen itself, but also remove a strong enemy. But the threat of the Qin State does not seem to be weaker than that of the Zhao State, so as the general of the Yan State, Su Cheng is also very conflicted in his heart.

"Is there still less benefit to Yan Guolao? When you are fighting, you hide behind, and when you are shooting and belonging, you are more active than anyone else! Zhao Cong, the general of Zhao State, angrily reprimanded the greed of Su Cheng, the general of Yan State. At the same time, Zhao Cong also hated Yan State, because Yan State had always coveted the land of Zhao State, especially after the defeat of Zhao State Changping, Yan State had been treacherous and repeatedly tore up the alliance to attack Zhao State. Fortunately, Zhao Guoyou Lian Po, Li Mu, Pang Xuan and other veterans supported the scene, otherwise the consequences would be unimaginable.

Wu Qiang, the general of the Wei State, had just lost the grain and grass, and he blamed himself, let alone express any opinions, and sat on the side, silent.

The coalition forces have different agendas, and it is difficult to reach a unified opinion.

A strange phenomenon appeared, the coalition army of the labor expedition stopped, and the Qin army could not hold out!

No war in the city! Yucheng is only eighty miles away from Xianyang!

The Six Nations knew that it was impossible to fight with the Qin State, which was known as "a million heroes and a thousand chariots", but they were unwilling to cooperate sincerely with other countries, lest other countries become stronger. As a result, the six countries had their own hearts and minds, and excused each other for excuses, and the good policy of "joining forces to attack Qin", which could have competed with Qin, was in vain in terms of corrupt ideas and selfish psychological effects.

When attacking Qin, the composition of the armies of the six countries was complicated, and they knew that the Qin army was strong and did not want to take the lead, and even hoped that other countries would lose more in the process of attacking Qin, so that they could take advantage of the fire to rob. The most hard-working person in the five kingdoms attacking Qin every time was Han Wei, followed by Zhao Chu, because Han Wei had immediate interests to gain (land) in attacking Qin, Qi and Yan were far away, and they had no immediate interests in attacking Qin, and they were unwilling to work hard, and working hard was also the benefit of Han Wei and Zhao Chu. Therefore, the uneven interests lead to the inability of the five countries to unite, and if there is no great country with the ambition of weak Qin, it is difficult to shake the foundation of Qin.

Yucheng, the commander of the Qin army.

"Haha...... The Five-Nation Alliance is short of food and grass, and the people are sleepy and lacking horses, how can they fight? Qin Xiang Lu Buwei was very happy when he heard the latest battle report.

"I didn't expect that the cavalry could also play such a big role, and the Meng family is really talented." As the new leader of the Wang family, Wang Jian praised sincerely.

"Actually, Wu Anjun used cavalry to cut off the back road of the Changping Zhao army since Bai Qi, and the two little guys are just learning and using them lively." The old general was old and refined, so he was naturally modest and cautious, and then said tentatively, "It's just that hundreds of ploughing cattle have been killed and injured and violated the laws of Qin, how can I explain to the king of Qin?" ”

In the Battle of Changping, Wu Anjun Bai Qi once ordered a force of 25,000 to raid the rear of the Zhao army's attacking force, cut off the rear road of the Zhao army, and ordered a cavalry force of 5,000 people to insert between the Zhao army and the barracks, dividing the main force of the Zhao army into two isolated troops, and cutting off the grain route of the Zhao army. Eventually, it led to the crushing defeat of the Zhao State.
