As the old saying goes, "There is no eternal enemy, no eternal friend, only eternal interests", after the Zhao Wei and Han Sanjin alliances passed the honeymoon period, they resumed the ancestral tradition - nest fighting. The foundation of the Three Jins Alliance was already unstable, and the basis of existence was only because the Three Jins had just established the country at that time, the regime was unstable and worried about the aggression of external forces, coupled with Wei Wenhou's superb diplomatic art. When the regimes of various countries are stabilized, the basis for the existence of the alliance will naturally be gone. Moreover, the countries of the alliance were not equal, and the two countries of Zhao and Han became vassals and followers of the State of Wei, and zhao and Han had long been unhappy that the Wei family was dominant, and the Three Jins Alliance began to conceive a ghost fetus and look like a god, until it finally disintegrated.
After the death of Wei Wenhou, who had ruled for 50 years, the Three Jins Alliance completely collapsed, and the newly succeeded Marquis Wu of Wei changed Wei Wenhou's policy of uniting the Three Jins to weaken the Qin state and began to seek hegemony in the world alone. And a large number of reuse of the royal family, so that no background talents have no hope of rising have gone abroad, the most typical of which is Wu Qi. After the death of Marquis Wen of Wei, Wu Qi was jealous of Marquis Wu of Wei and had to go into exile in other countries, eventually coming to the State of Chu. At that time, the State of Chu had just been defeated by the State of Wei, and the King of Chu Mourning tried to revitalize the State of Chu, entrusted Wu Qi with a heavy responsibility, fully supported Wu Qi's plan to reform the State of Chu, and in just three years, with the joint efforts of Wu Qi and King Chu Mourning, the State of Chu was revitalized and became the only great power that could compete with the newly rising State of Wei at that time.
To be sure, Marquis Wu of Wei was not an incompetent man, as early as when he was crown prince, he commanded a large army alone, and with the famous general Le Yang (who was the second most famous general in the world after Wu Qi at that time) crossed the Zhao state to attack the Zhongshan state of the kingdom (to supplement the history of the Zhongshan kingdom, the Zhongshan kingdom was the only kingdom established by the non-Han nationality in the Spring and Autumn Warring States period, and the three families occupied the northeast of the Jin state at a time when the political situation of the Jin state was constantly changing and internal strife, that is, the northeast of shanxi province and the taihang Mountain region in the northwest of Hebei Province. and build on this basis. Because all four sides are adjacent to the Zhao Kingdom, also known as the Country within a State). As a monarch, Marquis Wu of Wei was obviously brave and good at war, and he was decisive and capable as a competent monarch. However, in terms of strategic layout and diplomatic planning, Wei Wuhou was obviously inferior to his father Wei Wenhou, and although the conquest on all sides greatly increased the territory of the State of Wei, there were also too many enemies, so that for many years there was no opportunity to recuperate, and the national strength was gradually declining. The decline of the State of Wei began precisely in the era of Marquis Wu of Wei, but due to the decisiveness of Marquis Wu of Wei and the ability to fight bravely and well, for a while the countries could not shake the hegemonic position of the State of Wei.
After the death of Marquis Wu of Wei, who ruled for 25 years, the international status of the State of Wei further declined, and the Three Jin Alliance was still in name only, and by the time of the successor King Hui of Wei, the name was gone, and the Three Jin League had completely disappeared as a historical term. Not only that, but the Three Jins also began infighting, which is equivalent to saying that the State of Wei not only lost two allies, but also added two enemies. The strength of the State of Wei has greatly declined, and the surrounding Qin, Chu, and Qi states have also begun to change the law and innovate, and their strength has greatly increased. The State of Wei is located in the center, the development space is small, and the State of Qin is in full swing to carry out the Shang Martingale Transformation Law, and in the long run, the Xihe County occupied by the State of Qin by the State of Wei will not be guaranteed. There were two paths before the State of Wei, one was to continue to unite with the Three Jins to attack the State of Qin as much as possible at a favorable time when the qin state's change of law had not yet borne fruit; second, to take advantage of the fact that the state of Wei was still strong and Wei Wu's combat strength was still there, to attack Zhao and Han, and to unify the three Jin regions, so as to take advantage of the fact that the state of Wei was still strong and Wei Wu was still in combat strength, and to unify the three Jin regions, so as to use this as a backing for domination of the world.
If King Hui of Wei had chosen the plan to destroy Qin, perhaps later history would have been rewritten, in fact, at that time, if the Three Jins could really jointly cut down Qin, it would not be difficult to destroy Qin, and it would not be difficult to take ten thousand steps back, even with the strength of the State of Wei alone, it could greatly weaken the State of Qin, and then terminate the change of the State of Qin, and the State of Wei could obtain a large amount of supplies from the area occupied by the State of Qin. Unfortunately, the State of Wei chose the second plan, King Hui of Wei appointed the general Pang Juan as a general, commanding more than 100,000 elite troops of the State of Wei to attack the State of Zhao, and under the powerful offensive of the Wei army, the Zhao army gradually fell into disband and had to seek military assistance from the State of Qi. The King of Qi Wei took Tian Ji as his general, Sun Zhi as his military division, and commanded the Qi State to aid the Zhao Army to rescue the Zhao State, and Sun Zhen used the strategy of encircling Wei to save Zhao, which made Pang Juan's attempt to destroy Zhao fall short. More than ten years later, King Hui of Wei again appointed Pang Juan as a general, commanding more than 100,000 troops to attack Korea, Korea followed the example of Zhao Guo to seek help from the State of Qi, king of Qi Wei again appointed Tian Ji as a general, Sun Bing as the commander of the military division Qi Guo to aid the Korean legion to rescue Korea, Sun Zhi used the strategy of luring the enemy to go deeper, set up an ambush at Maling and defeated the Wei army, the Wei army general Pang Juan was killed, the elite army of the State of Wei was completely destroyed, and even the famous and invincible Wei Wushu legion was completely destroyed in the Battle of Maling. The elite of the Wei state in the Battle of Maling were lost, and they were no longer able to maintain hegemony.
Just when the news of the defeat of the Wei state of Maling reached the Qin state, the Qin state had just completed the Shang martingale transformation method that lasted for more than ten years, and the national strength of the Qin state had increased explosively, and the brightest new star that ended the chaotic world of the Eastern Zhou Dynasty for hundreds of years broke through the heavenly dome and prepared to glow its brightest light. After the change of law, the Qin state is in need of a victory to test the results of reform, but also urgently need a big victory to prove its existence, for a long time the Qin state has been despised by the nations, so that the Central Plains countries (central plains congresses) disdain to call the Qin state, the Qin state was isolated for a long time. Decades of oppression of the Qin state by the State of Wei have made the Qin people grumpy, and the fertile land of Hexi of the Qin people has now become the Xihe County of the State of Wei, which is a great shame that makes the Qin people breathless.
The sword was about to be sheathed, and after Qin Xiaogong learned of the defeat of the State of Wei, he immediately appointed Shang Martin, the chief architect of the reform and change of the Qin State, to command the newly trained Qin army to begin the war to recover the land of Hexi. King Hui of Wei was shocked when he heard the news of the invasion of the Qin army, but there was nothing he could do, the main force of the Wei army had been completely destroyed, and he had no troops to reinforce Xihe County except for the tens of thousands of people guarding the capital, and could only hope that the Wei defenders of Xihe County, the Hexi Army. The Hexi army was personally trained and reorganized by Wu Qi in accordance with wei Wuzhuo's standards, and later Wei Wuzu was transferred back to Wei to participate in every battle of Qi, Chu, Zhongshan, Zhao, and Han, and finally ended in Maling (to add, in the Battle of Maling, Wei Wuzu still fought tenaciously and covered the retreat of the Wei army when he was under siege, until the whole army was destroyed and the Qi army was severely damaged, so that the Qi army was unable to continue to attack the Wei state after victory, and Wei Wuzu was worthy of the title of the world's first strong army). The Hexi army has been stationed in Xihe for a long time, and the commander Long Jia has received the true transmission of Wu Qi, and he is deeply familiar with the art of war and is brave and good at war. When King Hui of Wei thought of this, his own tightening brow also slightly stretched, and he personally sent people to Xihe County to appease the generals of the Hexi Army, and entrusted Long Jia with full power, allowing him to command the Hexi Army against the Qin Army without any scruples.
When the "Black Legion" in the distance (the Qin people were still black, and the qin army's clothing was all black) gradually approached the camp of the Hexi Army, Long Jia was shocked by the scene in front of him, only to see the three armies of the Qin Army up and down, full of momentum and fighting spirit. As a battle-hardened general, Long Jia did not fight until this battle. But the honor of the soldier made it impossible for him to retreat, yes, where else can he go, whether to go to Anyi (the capital of the State of Wei). All the conspiracies and tricks are useless, and this battle is all about strength and combat strength. The moment the Hexi Army rushed towards the Qin Army, it was as if the world had fallen silent. In half a day, Wu Qi's painstaking training of the Hexi Army, which had been practicing for decades, was completely destroyed, and compared to the death of their brother Wei Wupao in the Battle of Maling, the Hexi Army was happy, because they were killed in the attack on another stronger Wei Wupao, the "Black Legion", and as soldiers, there was no better home than this. For the Qin army, the Hexi army was a respectable opponent, and they buried these Wei warriors (including their commander Long Jia), although these Wei soldiers had occupied the Qin people's hometown for a long time, they still deserved the respect of the Qin army.
When the news of Long Jia's suicide and martyrdom and the total destruction of the Hexi army reached Anyi, King Hui of Wei was already desperate, and in just a few decades, the State of Wei had degenerated from a hegemon in the world to a child who was deceived by others, and the two magic weapons on which he relied for hegemony, Wei Wupao and the Hexi Army, were completely destroyed within a few years. In desperation, King Hui of Wei had no choice but to cede Xihe Commandery to the State of Qin, and moved the capital from Anyi near Hexi to Daliang, completely abandoning the land where generations of Wei soldiers fought in blood. After the two major battles of Maling and Hexi, the State of Wei collapsed, and the first "leading big brother" of the Warring States Era reluctantly bid farewell to the throne of the boss and actively played a supporting role on the stage of the Warring States in the following hundred years.
