The wind rises and the flag hunts.

In the Turkish army fortress, Zhao Jia stood on the city wall, looking at the Qin army getting closer and closer, his face was solemn.

"Stomp, stomp!"

The sound of footsteps came from far and near, and the first general rode on the chariot and went straight to the bottom of the city wall.

"I am the Qin general Jing Ji, according to the king's edict, I will command 20,000 troops to help Zhao attack Yan, and I hope that the guards in the city will be able to release it!"

After speaking, Jing Ji took out the letter of alliance between the two countries from his bosom, as well as the customs clearance document promulgated by King Zhao himself, and signaled his subordinates to send it into the city along the hanging basket.

After Han Cang became the prime minister of Zhao Zhiguo, there were countless defectors, and he quickly suppressed Pang Nuan's factions that advocated unity, and Zhao Yan was also determined to attack Yan with Qin.

This time, Zhao Yan can be described as resolute, and as soon as the two countries finished discussing the matter of attacking Yan, they urged Qin to send troops to Zhao to support.

Qin didn't want to send troops so quickly, but he was worried that delaying would make King Zhao unhappy, and after all, there were still quite a few anti-Qin factions in the Zhao court.

After thinking about it repeatedly, Lü Buwei finally sent Jing Ji to command 20,000 soldiers and horses into the Zhao State.

At the same time, the territory of Qin also began to recruit troops and horses on a large scale, preparing to send troops to attack Korea.

Zhao Jia looked at the majestic Jing Ji on the chariot, but he couldn't remember the slightest record of this person in his mind.

"Has this ever happened in history?"

Zhao Jia frowned, feeling that things were a little beyond his expectations, and he was also full of fear and defense against the 20,000 soldiers and horses commanded by Jing Ji.

What Zhao Jia didn't know was that there was indeed a Jing Ji person in history, but his name was not recorded in the "Warring States Policy" or "Historical Records".

"The Book of the Warring States Period" records: Qin envoy Jing Ji according to Zhao attacked Yan and pulled out the second city. Yan made Cai Niao (should be Cai Ze) into Qin, and sealed the letter to the Marquis with the ten cities between the rivers.

This book was unearthed in 1973, the book has a total of 27 articles, one of which is similar to the "Warring States Policy", and there are 11 articles with the same content and text as the current "Warring States Policy" and "Historical Records".

Although Zhao Jia had never heard of Jing Ji, he knew that Li Mu led his troops to capture the two cities of Yan at the beginning of Zhao Yan's succession.

"Historical Records": In the first year of King Xiang of Zhao, Lian Po died in Wei, and Zhao made Li Mu attack Yan, pull out Wusui and Fangcheng.

Combined with the "Warring States Zongheng Family Letter", it can be speculated that it was in this year that Li Mu and Jing Ji jointly captured the two cities of Yan State.

This war was also the beginning of Qin's frenzied expansion.

What do you say?

Just when the Qin State sent the Jingji Alliance Zhao State to attack Yan, he ordered the veteran general Meng Yu to lead the troops to attack Han, and captured fifteen cities in Korea one after another.

Fifteen Korean cities made the already weak South Korea lose nearly half of its territory, and because Korea is close to Zhao in the north, after losing these lands, it also exposed Zhao Handan to Qin's troops.

Immediately afterwards, due to the attack on Yan by the Qin and Zhao coalition armies, the Yan Kingdom was panicked.

There is a minister under the command of King Yan, called Cai Ze.

Cai Ze was originally a Yan person, and he wanted to become a leader after he learned something, but he repeatedly hit a wall and couldn't be reused at all.

In desperation, Cai Ze went to the Qin State, and was valued by Qin Prime Minister Fan Sui, and strongly recommended it to King Qin Zhaoxiang, and was awarded the position of guest secretary.

It's a pity that Cai Ze only served as Xiangguo for a few months, and he was slandered by others, he was worried about being killed, so he resigned from the position of Xiangguo under the pretext of illness, so he was able to save himself, and was named Gangchengjun instead.

In the year that Qin Shi Huang succeeded to the throne, Lü Buwei sent Cai Ze to Yan as an official, and it has been three years since then.

Seeing that Yan was attacked by the combined forces of Qin and Zhao, and there was already a disaster of losing the country, Cai Ze proposed to King Yan to bribe Qin Prime Minister Lü Buwei with the ten cities of Hejian to destroy the alliance between Qin and Zhao.

The fertile land between the rivers is jointly managed by Zhao and Yan, and if a piece of Qin territory is added in the middle, it can also reduce the pressure on Yan State.

Although the king of Yan was reluctant to build ten cities, considering that if Qin and Zhao continued to form an alliance, the Yan country would be ruined, so he had to act according to the plan.

So, King Zhao Yan sent Cai Ze into Qin and bribed Lü Buwei with ten cities in the river, and Qin obtained ten cities in Yan without spending a single soldier.

I have to say that Lü Buwei played this trick very beautifully, first attacking Yan with Zhao, which not only destroyed the alliance of Hezong and created an opportunity for Qin to attack Korea, but also frightened Yan Guo to offer ten cities with both hands.

Yan and Zhao were both toyed with by Lü Buwei in applause.

More exaggerated things are yet to come.

Lü Buwei was still not satisfied after obtaining the ten cities of Hejian, and wanted to attack Zhao Yiguang's fiefdom between the rivers, so he prepared to form an alliance with Yan.

In order to ensure the validity of the alliance between the two countries, Lü Buwei sent Zhang Tang to Yan as his prime minister, and asked Yan to send Prince Dan to Qin as a hostage.

King Yan happily agreed, relying on the breakdown of the alliance between Qin and Zhao, relying on the mountain of Qin behind him, so he raised troops to attack Zhao, wanting to recapture the city captured by Li Mu.

If at this time, the Qin State and the Yan State attack Zhao, if the Zhao State does not have the help of other countries, it will indeed be more auspicious.

It's a pity that the Qin State did not send troops, and the inflated Yan State was defeated by Pang Nuan instead, and it became Pang Nuan's first victory since he worshiped the general.

At the same time, Lü Buwei sent Gan Luo as an envoy to Zhao.

Gan Luo was clever and told the King of Zhao: The Marquis of Wenxin wants to attack Zhao, and he is also Guanghejian. The king is not as good as the five cities of the five cities to the Guanghe River, please return to the prince of Yan, and attack the weak Yan with the strong Zhao.

Zhao was afraid of Qin and wanted to maintain an alliance with Qin, so he immediately agreed to this condition and sent five cities to Guanglu Buwei River fiefdom.

So the state of Qin was replaced by Prince Yan.

Zhao attacked Yan and got thirty cities in the valley, so that Qin had eleven.

I have to say that Lü Buwei's series of operations are simply wonderful, first with Zhao Fengyan, destroying the alliance and giving Qin a chance to capture fifteen cities in Korea.

Immediately after taking advantage of the psychology of Yan and Zhao to fear the Qin State, the empty glove white wolf got the ten cities of Hejian from Yan State, and then another threat, and the soldiers got the five cities of Hejian of Zhao State without blood.

Even among the thirty cities of Yan that Zhao worked so hard to build, Qin also got eleven.

Without going through war, just relying on repeated treacherous diplomatic means and the strong national strength of Qin, he obtained twenty-six cities of Yan and Zhao without bloodshed.

If you add the fifteen cities in Korea, Lü Buwei's operation has added forty-one cities to the Qin State, which is almost equivalent to all the territory of the entire Korea.

These forty-one cities not only greatly expanded the territory of Qin, but also made all countries deeply feel the threat of Qin.

As a result, there was the matter of Pang Nuan's commander and the army attacking Qin.

Unfortunately, this alliance ended in failure, and it became the last time that the Kwantung princes joined forces during the Warring States period.

The momentum of the Qin State sweeping the world can no longer be stopped.

Now, the general trend of the world has reached a turning point in history, and whether it can prevent the general trend of Qin from unifying the world is inseparable from whether Zhao Jia can grasp this opportunity.
