Ji Zhi, the prince of Yan State, who was supported by the Song State and the Zhao State, had abundant strategic materials, and soon trained an army with the help of Taoqiu merchants.

Although the army was small, it numbered in the thousands. However, with his status as the son of Yan Guo, he quickly gained a firm foothold in the Yan State's resistance to the Qi State. And with the continuation of the Yan State Anti-Qi War, more and more Yan resistance forces have been invested under the banner of Ji Zhi!

When the war in Yan was still going on, the situation in all countries in the world began to change again.

After the Battle of Hangu Pass, half of the Qin State was invaded by the Xirong army led by Yiqu. This made the whole Qin State recognize a fact: Xirong is immortal, and the Qin State is uneasy! If the Qin State cannot completely solve the Xirong problem, it is said that it will go east to compete with other countries, even if it wants to develop steadily, it will be impossible!

After having this understanding, the Qin people were ruthless and launched a large-scale attack on Xirong in a row for several years!

With Qin's political system established entirely for war, coupled with the powerful military that even the Central Plains countries were extremely afraid of, Yiqu and other Xirong tribes were no match for Qin at all! The Qin State quickly recovered the cities that had been recaptured by Xirong, and with the efforts of the elite soldiers of the Qin State, the Qin State even once fought into the depths of the grassland and captured the twenty-five cities of Xirong!

As a result, Sijon's strength was greatly damaged, and the tribes had to submit to him again. This time, the Qin State did not let Xirong go as much as before. According to the land of Xirong, and even the different strengths of the tribes living in this land, the Qin State carried out classified management.

For many small and medium-sized tribes that were relatively weak and did not dare to resist the Qin State, the Qin State merged them together and merged them into one county, and sent county officials such as county commanders to rule. For the stronger tribes such as Yiqu and Wushi, the Qin State also set them up as independent counties, and their clan leaders must be vassals to the Qin State and rule the tribes as the county commanders of the Qin State.

Of course, considering that the Qin State itself did not have the strength to completely disperse Xirong and let it be under the direct rule of the central government of the Qin State. The Qin State agreed in principle that the official positions of these tribal leaders could be inherited.

In this way, these big clan leaders take over the county order, which is equivalent to a kind of local official who can be hereditary. Qin's flexible and pragmatic statecraft allowed it to quickly stabilize the western region, and also allowed Qin to withdraw its strength from the western frontier to deal with the eastern states!

After all, the Qi State's destruction of Yan in January was really a big shock to the Qin State!

After the Qin State withdrew its hands and feet from the west, it immediately threw in a large army and continued its strategy of going eastward! Its goal is still aimed at Wei Han!

In August 314 BC, less than two months after the destruction of Yan, the king of Qin sent a large army to attack Wei and Korea under the pretext that Han and Wei had betrayed Qin. Han Wei knew that he was invincible, so he had to frantically ask for help from the surrounding countries!

With Qi Yanyan's proud exploits, now the confidence of the entire Qi country is greatly boosted! Thanks to this confidence, as well as Qi's fear of Qin's rise, Qi soon joined Chu to discuss a strategy to deal with Qin!

The Chu State has a hot-blooded element like Qu Yuan, plus Ling Yin Fuguo, who has a rational and pragmatic person like Zhaoyang, is extremely vigilant against the ambitions of the Qin State! And the alliance between Qi and Chu can be reached quickly, which is also due to the powerful combat power of the Qin State in the previous Hangu Pass battle!

Qi, Qin, and Chu, the three great powers scattered in the east, west, and south of the world, have formed a strategic situation of a large triangle in terms of their positions and specific strengths. These three big countries are like the three sides of a triangle, and neither country can help the other two, so everyone can only maintain a posture of cooperation and mutual vigilance at the same time!

Now because the strength of Qin is too strong, the two big countries of Qi and Chu, in order to fight against Qiang Qin, can only "huddle together for warmth"! Of course, the foundation of the alliance formed by the two countries of Qi and Chu is changing with the change of strength between the three countries, and it is not an alliance with deep heritage!

However, even so, when the two great powers of Qi and Chu began to support Han and Wei at the same time, and sent large armies to these two countries to resist the invasion of the Qin army, Qin's eastward strategy was suddenly under great pressure!

Under the call of the State of Qi, the states of Qi, Chu, Han, and Wei began to rise together to oppose the crusade of the State of Qin! Qi and Chu even personally sent large armies to Han and Wei to help the two countries defend their imperial cities!

And the Qi State, which had seen the strength of the Song State in the Battle of Cutting Yan, naturally would not leave such a powerful little brother behind! Dai Yan was sandwiched between the two countries of Qi and Chu, so he naturally did not dare to refuse the request of the two powers, so he also sent a large army to participate in the battle of Qin!

This war is the first time that Dai Yan has been hostile to the Qin State since he took charge of the Song State! Out of vigilance against the Qin State, he ordered Le Yi to lead 30,000 elite soldiers to follow the army of the Qi State and participate in this war with the Qin State!

To be honest, out of vigilance against the Qin State, he didn't want to confront the Qin army so soon. Therefore, this time he sent troops, and he did not let the Taoqiu merchants play an extremely efficient fundraising method to quickly transfer grain and grass as in the previous battle of Fayan. Instead, let the local guards prepare sufficient food before sending troops slowly!

Dai Yan originally thought that his actions would be reprimanded by Qi Guo, but he didn't expect Qi Guo to have the same idea as him!

When the soldiers and horses of the Chu State had already rushed to the country of Han and Wei, the soldiers and horses of the Qi State had not even surpassed Taoqiu! Such a slow marching speed naturally made Dai Yan suspicious, and he couldn't help but wonder if the Qi army had other intentions!

But soon, he saw through the plot of Qi from the changes in the situation in the world!

Although Qin was a little jealous of Qi and Chu's move to rise up against Qin together, he would not be directly deterred by diplomatic intimidation! In September, a month after the Qin State sent troops, they fought the Wei army at Jiaocheng and conquered the city. Half a month later, the Qin army fought with the Korean army at the shore gate, won a big victory, and beheaded tens of thousands of Korean troops!

However, when the Qin army continued to advance the battle line and wanted to attack Yiyang, South Korea, and prepare to take this Korean Xiongcheng in one go, it began to be counterattacked by the armies of Han, Wei, and Chu at the same time!

During the Battle of Hangu Pass, although the Qin State was able to defeat the Three Jin Coalition forces at one time, it was a defensive operation within the territory after all! However, when the battle line advanced to Korea, the nature of the war had changed, and at this moment it was already a war in which the Qin State single-handedly crusaded against the Three Kingdoms, and it was obvious that the Qin State did not have such strength!

The Qin army stopped outside the city of Yiyang, and then the Qin state formed a situation of parity with the three kingdoms of Chu, Wei, and Han, and under this balance of power, no one could help anyone! And in such a situation, the marching speed of the Qi army and the Song army suddenly accelerated, and they began to reach the Wei State quickly!

The arrival of the Qi and Song coalition forces immediately became the most critical force on the battlefield!

Qi Guo chose to make a move at the most critical time, naturally it was not without reason. If it sends troops early and starts to confront Qin with Wei Han and other countries, it will consume Qi's military strength to a large extent. Since the Battle of Sanqiu many years ago, when the Qi army had seen the invincible power of the Qin army, the Qi country tried its best to avoid a decisive battle with the Qin army!

Now that the Qi army has appeared in the Wei State and will soon appear on the battlefield, it has undoubtedly become a key force to break the confrontation between the two sides!

Although the Qi army is now on the side of the Chu State, it is to prevent Han and Wei from fighting with the Qin State, but the Qi State itself and the Chu State are not completely of the same mind! Qi participated in this war to obtain the benefits of the war, not for the safety of Han and Wei!

And the Qi army came to the battlefield, because it had a key force in its hands, it began to mediate the war between the Qin State and the three kingdoms of Chu, Wei and Han! And at such a moment, the State of Qi is not completely on the side of the State of Chu, it is also in contact with the State of Qin!

Such a move immediately made Chu State, Han, Wei and other countries extremely nervous! Especially the two countries of Han and Wei, if they were attacked by Qin and Qi at the same time, they would fall into an extremely tragic two-front battle!

Therefore, Chu, Wei, and Han had to give a lot of benefits to Qi to win over Qi!

In this simple war, the Qi State dispatched a small number of troops, and did not fall into the war, so it reaped the greatest benefits, which made the Chu, Wei, and Han countries extremely dissatisfied, but they did not dare to attack. However, the Qin State completely ignored the attitude of the Qi State!

In Qin's view, Qi State's contact with him was just creating a bargaining chip out of thin air to force Chu, Wei, and Han Kingdoms to give up more benefits! In this regard, although the Qi State has gained small profits, it has lost its faith and lost great profits!

As a result, Qin severed its ties with Qi and privately negotiated with Han and Wei.

After Zhang Yi personally went out, the Qin State once again took the initiative to retract the soldiers and horses back to Hangu Pass, and returned the newly captured Jiaocheng of Wei and the shore gate of South Korea! Qin made such a big concession, naturally it needed to be reciprocated by Han and Wei!

Zhang Yi's conditions were not excessive: Han and Wei formed an alliance with the Qin state and paid tribute to the Qin state! As the sincerity of the alliance between the two countries, South Korea needs to send the crown prince Hancang to Xianyang as a hostage; And the Wei State needs to set up a pro-Qin prince as the prince of the Wei State!

Wei and Han naturally did not dare to refuse Qin's request, and they both agreed. After all, what the two countries feared most before was that the Qin State continued to encroach on the land of the two countries. Now that the Qin State is willing to influence the national politics of the two countries through protons and the canonization of the pro-Qin faction, although the two countries will have troubles in the long run, at least the immediate urgent need is solved!

And the two countries of Wei and Han, which received the strong support of the Qin State, immediately hardened their waists! At the same time, the two countries issued an ultimatum to Qi and Chu, demanding that the armies of the two countries withdraw from the two countries within a time limit!
