Counting the Ming Emperor of the Qin State during the Warring States period, if Qin Xiaogong was the first, then King Huiwen of Qin was the second most deserved; during the period of King Huiwen of Qin, he continued to implement the "Martingale Transformation Law" internally and actively opened up the territory and expanded the territory externally, so it is not an exaggeration to say that during the twenty-seven years of King Qin Huiwen's reign, the Northern Expedition Yiqu, Xiping Bashu, The East Out of Han Valley, and the South Shangyu, the territory of the Qin State was more than doubled, laying the most solid foundation for the qin state to unify the world.
And King Huiwen of Qin was able to achieve such achievements, which had a great relationship with his wisdom and wisdom, the use of talents by Ren Xian, and the selection of talents, and he not only reused Qin people such as Yin Hua, half-brother Gongzi Disease, and Sima Cuo, but also reused a large number of foreign able subjects. Wei people such as Gongsun Yan, Zhang Yi, and Wei Zhang could all be reused for YinSi. After having so many outstanding talents, listening to opinions has become a "torture", after all, the opinions put forward by these people are basically correct, depending on how to choose.
And what I want to talk about here is an incident that happened during the reign of King Huiwen of Qin. In 316 BC, the southern kingdoms of Ba and Shu suddenly attacked each other, but the strength of this Kingdom and the State of Shu was almost the same, so they both sent emissaries to the State of Qin to ask for help from the State of Qin. King Huiwen of Qin wanted to send an army to attack the Shu state, but he hesitated because he was afraid that the road was dangerous and difficult, and feared that Korea might come to invade.
At this time, these ministers naturally wanted to give advice to King Huiwen of Qin and provide advice on the decision of King Huiwen of Qin; at that time, Sima Que and Zhang Yi, the secretary of The Qing, argued endlessly in front of King Huiwen of Qin, and Zhang Yi advocated that he should attack Korea first; while Sima Que lied to Zhang Yi's proposal, believing that attacking Korea would lead to a joint confrontation between the princes against the State of Qin, and attacking the State of Shu would not only obtain its manpower and material resources to enrich the armament, but also occupy favorable terrain and attack the State of Chu by going down the water.
It can be said that this Sima Mistake and Zhang Yi's suggestion seem to be of no use, and it is still an ambiguous answer to King Qin Huiwen; but King Qin Huiwen is different, he got a lot of useful information from the controversy between Sima Mistake and Zhang Yi, especially the information obtained from Sima Yi, which made King Qin Huiwen firm in his determination to attack the land of Bashu, after all, the road in the land of Bashu is dangerous, if it were not for this sudden opportunity, I am afraid that it would be almost impossible for the State of Qin to enter the Shu Han.
Therefore, King Huiwen of Qin eventually ordered Sima Que, Zhang Yi, Du Weimo, and others to lead an army from ShiniuDao to attack the Shu state. In the end, the Qin army experienced difficulties and engaged the Shu army in Yemeng, and the Shu army, especially the opponent of the Qin army? The Shu king's soldiers fled to Wuyang in defeat. It did not take long for the Qin army to destroy the Shu state and demote the king of Shu to the title of Marquis of Shu; after the Qin state annexed the Shu state, it became richer and stronger and despised the surrounding countries.
After that, according to Sima Que's advice, he sent Zhang Yi to the State of Chu to carry out a counter-plot to induce the State of Chu to break off diplomatic relations with the State of Qi. Then he designed to provoke the king of Chu Huai and induce the Chu state to risk sending troops to attack Qin; this time the Chu state attacked the Qin state with hatred and did not prepare for war, but the Qin state had long been prepared for war, so the Qin army defeated the Chu army in Danyang and obtained the Hanzhong land of the Chu state. The threat of the State of Chu to the mainland of the State of Qin and the State of Shu was removed. The state of Chu has since collapsed.
After this series of battles, the State of Qin obtained the lands of Hanzhong and Bashu, and also connected these two places with the land of Guanzhong, which not only obtained manpower and material resources to enrich the armament, but also made the Qin State form a condescending oppression situation against the Six Kingdoms. The whole situation under the heavens was reversed at once, and since then, the Qin State has changed from a powerful princely state to a super prince who can influence the situation under the world, and even has the ability to win the world.
If King Huiwen of Qin had listened to Zhang Yi's suggestion at that time and attacked Korea, not to mention whether he could take some cities, even if he had taken the whole of Korea, the role would be far less than that of taking the land of Bashu; after all, Korea was a land of four wars, and in the absence of sufficient strength, hastily obtaining the land of Korea would not only not bring substantial growth to the strength of the Qin state, but also increase the pressure in vain, so that the Shandong states would unite to besiege the Qin state. And taking the land of Bashu, a stable "granary", the help to the Qin state is self-evident, and the reason why the Qin state has the courage to carry out the "Battle of Changping" with the Zhao state is directly related to the funding of the land of Bashu.
