Song Guo's change of law is not a thing that can be completed in a short period of time. And just when Dai Yan was wholeheartedly taking care of the internal affairs of the Song Kingdom, the situation in the whole world began to change amazingly.

When the Song civil war detonated the chaos in the world, the king of Wei forcibly separated from Han and Zhao despite domestic opposition, and then took refuge in Chu, intending to obtain support from Chu to fight against Qin, and pinned his hopes on reaping benefits from Song in the east to make up for Wei itself.

However, the civil war of the Song Dynasty, and even the decisive battle with the Chu State, went on too quickly. Moreover, after the Song State demonstrated its strength, the Qi State made a decisive move to quell the battle of Song and Chu, and then successfully pulled the Song State to the side of the Qi State. And the whole world gradually calmed down with the action of Qi State.

After the war in the east subsided, the alliance between Wei and Chu did not disperse, but became closer because they were also threatened by Qin. In the face of the two countries of Wei and Chu, Qin had no choice but to shrink its forces and withdrew its army that was attacking Wei and Chu at the same time.

As a result, the world has entered a rare era of peace, and such an era is indeed extremely rare. This state of peace lasted for several years, and all countries did a lot of things during these years.

Chu, Wei, and Han also began to deal with domestic affairs, hoping to make up for the loss of national strength in the previous war. Under the advocacy of some Confucian scholars, Yan Guo began to set off a trend of Zen concession.

Zhao accelerated the pace of his Hufu cavalry reform, and the expeditions to the western and northern grasslands began to become more frequent. As for the Qin state, during this period, it also began to expand westward, defeating the once threatening Yiqu state, and the Yiqu king had to remove the throne and accept the canonization of the Qin king, becoming a vassal of the Qin state.

The pace of expansion of the Qin State and the Zhao State to the grassland at the same time suddenly caused a serious conflict of interests between these two countries, which were originally only bordering on remote areas! In this situation, the hostility of the Zhao State towards the Qin State also began to become stronger and stronger!

In this case, Sun Yan, the prince of Wei, saw an opportunity, and with his efforts, his strategy of cooperation and vertical was once again placed in front of the princes of the world!

The theme of this joint effort is still based on the crusade against the Qin State. In Gongsun Yan, Wei, Zhao, Chu, Korea, Yan and Zhongshan were invited to participate in the meeting, and everyone came to jointly crusade against Qin. Even the newly rising Song State, which performed eye-catching in the war with the Chu State, Gongsun Yan still sent an invitation!

Dai Yan ignored such an invitation at all, and directly asked the Ministry of Rites to refuse in an extremely tactful manner. At the same time, he also sent Gongsun Yan's invitation to the Qi State.

For Dai Yan, the current Song State is dominated by the Qi State on the bright side. It is impossible for Qi to be unaware of the diplomatic invitation sent by Gongsun Yan to the Song State, but the attitude of the Song State to report or not to report to the State of Qi is very crucial, and from this attitude, you can see the ambition of the Song State! Although the changes in the Song State made the entire Song State stronger, Dai Yan was not willing to directly challenge the authority of the Qi State now, let alone the Qi State was aware of the ambitions of the Song State.

At this stage, the Song State still implements the foreign policy of "Taoguang and obscurity, respecting Qi", at this stage, the Song State is a good little brother of the Qi State, helping the boss of the Qi State to shout and cheer, and reporting all kinds of information to the boss, and the Song State is basically worry-free.

As for Gongsun Yan's behavior of inviting all countries in the world to jointly crusade against Qin, Qi was also very worried about this. Although Hezong is obviously a crusade against Qin, Gongsun Yan's invitation, among the top countries in the world, is the only one who does not invite Qin and Qi, this kind of signal is very interesting.

In the eyes of the monarchs and ministers of the State of Qi, the behavior of Gongsun Yan and even the State of Wei is a great threat to the State of Qi, and the State of Qi must not sit idly by and watch the formation of the Conspiracy!

As a result, the state of Qi began to exert its strength, and at the same time threatened many countries that had close relations with the state of Qi and were diplomatically dependent on the state of Qi.

Under the leadership of Dai Yan, Song Guo naturally did not say anything, and completely stood on the side of the boss of Qi State. As for Zhongshan, when Qi did not blame it explicitly, he took the title of King of Zhongshan to talk about things, and accused Zhongshan State of being large and Zhongshan small, and King Zhongshan did not deserve the title of "king". At the same time, the State of Qi also launched a diplomatic offensive, calling on the State of Zhao and the State of Yan to jointly attack the State of Zhongshan!

Naturally, Zhao and Yan could not fall into the trap of Qi State, and the two countries jointly rejected Qi State's request. However, Zhongshan was frightened by the posture put forward by Qi State, and it no longer dared to stand with Hezong, and like Song State, it honestly attached itself to Qi State and stood on the side of Qi State.

In this way, there are only five countries in the whole world participating in the joint alliance: Chu, Wei, Zhao, Han, and Yan.

This time, the five kingdoms are united, which is different from the previous time when the five kingdoms were kings. It is not for nothing that the prime minister of the Five Kingdoms fell apart in such a short period of time. The lack of trust between countries is of course a problem, but the most important thing is that the five countries do not empathize with the threat of Qin, and at the same time, there is no really strong core among the five countries!

After all, when the Five Kingdoms were kings before, the strength of Zhao was no longer under Wei, but the King of Wei was rushing to be the commander of the alliance, which was a bit unworthy of the name. And the king of that time, Zhao Houyong did not claim the title of king, and was also considered by the world to be Zhao State's dissatisfaction with Wei State.

This time, the five countries were united, and the five countries had a full understanding of the ambitions of the Qin State, and everyone began to recognize the threat of the Qin State! And after Wei Guo recognized the situation in the world, and even Wei State's own strength, he honestly gave up the position of the chief of the longitudinal group! Among the countries of the alliance, the strength of the Chu State is the strongest, and Xiong Huai, the king of Chu, has thus become the chief of the world!

For this point, the magnates of all the countries involved in the alliance were all finalized in the Wei capital Liang. And the one who came to participate in the joint conference on behalf of the Chu State was Qu Yuan, the left disciple of the Chu State. When he got such news, he couldn't help but be excited!

In his opinion, the longitudinal commander is the overlord recognized by all countries in the world! How many years have passed now, and all countries in the world finally recognize the Chu State and regard the King of Chu as the overlord of the world, this is the glory of the Chu State!

After Qu Yuan completed the diplomatic mission for the Chu State, he became the companion of the King of Chu. And after the king of Chu ascended the throne, he was also reused by the king of Chu. And in the face of this great trust, he was also quite moved, and after the state of Chu became an important minister, he began to advocate "American politics" to govern the state of Chu!

U.S. politics advocates the selection of meritocrats, compassion for the people, and virtue in office. Qu Yuan has always been extremely opposed to the Qin state, which ruled in strict laws and brutal ways (in Qu Yuan's view)!

Now under the combined jurisdiction of the Five Kingdoms, the King of Chu can not only ascend to the position of overlord, but also use this as an order to weaken and even eliminate such a brutal country as Qin, not to mention how excited Qu Yuan is!

And when such news was transmitted back to the Chu State, the King of Chu was also extremely excited! Although he also has hostility towards the Qin State, it is not too strong, after all, he still has a sister who married into the Qin State!

However, when it comes to the position of the Qin State and the overlord of the world, Xiong Huai, the king of Chu, only struggled a little and abandoned the little family affection in his heart. Of course, his willingness to stand up and become the head of the joint longitudinal and make him an enemy of the Qin State, Qu Yuan and even Ling Yin Zhaoyang's lobbying is naturally an extremely important reason!

In this context, in 318 BC, the monarchs of Wei, Zhao, Han, and Yan came to Chu at the same time to participate in the alliance. At this meeting, the monarchs of various countries jointly elected Xiong Huai, the king of Chu, as the chief of the alliance, and agreed to jointly crusade against the Qin State!

After reaching this alliance, the five countries finally reached a specific agreement on the matter of cutting down Qin. Each country sent heavy troops, arrived at the border of Qin and Wei respectively, and when the armies of the five countries arrived, all countries marched into Hangu Pass together to crusade against Qin!

This time, unlike the last time when the Five Kingdoms were kings, all countries began to send troops and horses to attack Qin!

The reactions of countries outside the region that received the news were mixed.

The entire Qin Kingdom began to become flustered. The five kingdoms of Chu, Wei, Zhao, Han, and Yan, once they really send troops, can mobilize an army of more than one million! In the eyes of the Qin people, this is already a completely unstoppable force!

The political atmosphere of the Qin State began to change rapidly, and everyone believed that now the Qin State had fallen into the current situation of being the enemy of the whole world, because the King of Qin listened to the slanderous rumors of Zhang Yi, the villain of the Wei State, and insisted on implementing the strategy of going east! Qin should abandon Zhang Yi's foreign policy and shrink his troops back.

Some ministers of the Qin State even believed that the reality that the Qin State was blocked from going east in the Mu Gong era showed that once the Qin State got involved in the Central Plains, it would inevitably suffer a strong backlash from the Eastern countries! Now the Qin State should return to the policy of Mu Gong, claim the king in Hangu Pass, and dominate Xirong!

Some radical ministers even directly suggested that the King of Qin hand over Zhang Yi to the Five Kingdoms to apologize, as a signal that the Qin State would not be an enemy of the Five Kingdoms!

Under such a strong public opinion offensive, even the King of Qin had to make compromises and began to slowly shrink his forces to the Guannai. With such an obvious signal, Zhang Yi also had to make a statement and ask to resign as the prime minister of Qin!

King Qin naturally rejected Zhang Yi's request, and began to put pressure on Zhang Yi directly, asking Zhang Yi to come up with a specific way to deal with the crusade of the five eastern countries!

The other three powerful countries Qi, Song, and Zhongshan, which have nothing to do with Hezong and have nothing to do with Qin, are completely in a posture of sitting on the mountain and watching the tiger fight. Although none of the three kingdoms directly participated in the war between Hezong and Qin, under the order of the King of Qi, the three kingdoms also began to mobilize and remain vigilant against the Hezong countries!

In the eyes of the Qi State, this time the Five Kingdoms attacked Qin, and the Qin State was facing such a overwhelming situation of Mount Tai, so it was naturally bound to lose! And the five kingdoms that attacked Qin would inevitably expend great strength in such a war! At that time, the world will become a two-headed war for hegemony dominated by Qi and Chu!

The results of such an analysis, the envoys sent by the Qi State, were all completely revealed to the Song State. Under such a signal, Qi State attaches more importance to the strength of Song State, in their minds, Song State will definitely be the front line of Qi and Chu hegemony in the future, the stronger Song State is, the more beneficial it will be for Qi State!

And Qi Guo's attitude undoubtedly reduced the obstacles to Song Guo's law changes! Regarding Qi Guo's judgment, Dai Yan almost went crazy with laughter! In later generations, the Qin State, which was so powerful that it swept through Liuhe, could it be easily defeated or even destroyed with such a simple merger?

No one knows better than him how powerful the Qin State can burst out in the face of danger! This time, he was not optimistic that the five countries would be able to win the war!

Dai Yan was not interested in the specific war, he just wanted to make the Song Kingdom stronger in this short period of time! Because he knows very well that once the war between the Five Kingdoms and the Qin State is over and the world recognizes the strength of the Qin State, the two countries of Qi and Chu will conclude an alliance, and at that time, the Song State, which is inserted in the middle of the two countries, will become an eyesore thorn in the side!
