Zhao Dan was thinking.

Thinking about this battle of Changping.

The Battle of Changping was not a war that broke out by chance, nor was it a simple war.

It is a war that will inevitably break out between Qin and Zhao, and it will inevitably break out in Shangdang County, and any game between Qin and Zhao will only delay or advance the time point when this war will inevitably break out in Shangdang County.

Why? This brings us to the geographical location of Shangdang County.

Shangdang County, where Changping is located, is located in the south of the Taihang Mountains in the north-south direction, this mountain range of thousands of miles has countless branches, which are full of lofty mountains and mountains, known as the "spine of the world", standing in the Central Plains, looking down on the four directions of the world.

It is like a huge, towering super pyramid standing in the north of the Yellow River, holding the key points of the Central Plains, easy to defend and difficult to attack. As long as any country occupies it, it will be able to gain a condescending advantage in the process of competing for world domination.

The rise of the Jin Kingdom, the overlord of the Spring and Autumn Period, began with the inclusion of Taihang Mountain in the territory of the Jin Kingdom. With the Taihang Mountains as the commanding heights, the Jin State had a topographical advantage over the Qi State in the east, the Chu State in the south, and the Qin State in the west.

Although the Jin State has always had a tradition of civil strife because of the strange Liuqing ruling system, with the Taihang Mountain Range, which is easy to defend and difficult to attack, even the Jin State during civil strife can easily resist the invasion of the enemy country. And after the Jin State ended the civil strife, the powerful Jin army was able to swarm out of the Taihang Mountains and suppress all the dissatisfaction in the world.

There are a total of eight east-west roads in the Taihang Mountains for the army to pass, and people collectively call these eight roads "Taihang Bashan". These eight are the military capital, Puyin, Flying Fox and Jing of North Taihang, as well as Fukou, Bai, Yanggu, and Yiguan of South Taihang. Coupled with a north-south Taihang and an east-west Kuihan channel, a total of ten roads are passable.

As long as you master the entrances and exits of these ten roads, you can completely control the entire Taihang Mountain Range.

If you control the Taihang Mountains, you will control the general trend of the world.

Historically, when the Qin State occupied these ten roads, it took only seven years to complete the great cause of unification cleanly.

Of course, there is a reason why the Qin State is already strong enough to be flattened, but the reason why the Qin State can be flattened so thoroughly and quickly also has a lot to do with the geographical advantages of the Taihang Mountains, the spine of the world.

The Taihang Mountains are divided into two halves in the north and south, and now the Shangdang County that the Qin and Zhao countries are fighting for, its territory contains most of the South Taihang Mountains.

There are a total of four roads in Shangdang County, one of which is located in the passage of the North Shangdang, called Fukou Mountain.

This Fukou is also the most critical factor in why the young King Zhao Xiaocheng decided to send troops to Shangdang County against public opinion, which eventually led to the Battle of Changping.

Fukou Cheng traverses the South Taihang in Shangdang County, and the east exit is not far from the important town of Zhao State, Wu'an, and then east of Wu'an is Handan, the capital of Zhao State.

The western exit of Fukou is the Jinyang Basin, where the Zhao family relied to make a fortune and establish the Zhao State's base camp Jinyang City.

Whether it is Jinyang or Handan, it is the core lifeblood of Zhao State. Jinyang and Handan are located on both sides of the Taihang Mountain, and Fukou is just the closest passage between Jinyang and Handan, which shows the importance of Fukou to Zhao.

As a generation of Ming monarchs, it is certainly impossible for Qin Wangji not to realize the importance of Fukou, in fact, the Battle of Changping is already the second war between Qin and Zhao over the control of Taihang Mountain.

As early as nine years ago, Qin Wangji had tried to use the advantage of Fukou to attack Zhao, a strong enemy.

In the great battle nine years ago, the Qin army took advantage of the Korean Shangdang to attack Wu'an, the western gate of Handan, along the east of Fukou, and then the Qin and Zhao sides fought a decisive battle in Yanhe.

Zhao Kuo's father, Ma Fujun Zhao Hao, led the Zhao army to eliminate 100,000 Qin troops in this battle, and killed Hu Yang, the most powerful assistant of Wu Anjun Bai Qi and the second general of the Qin State at that time, and achieved a great victory that shocked the world.

This defeat made Qin Wangji realize that it was very difficult to bypass South Korea to attack Zhao, and when he was thinking hard, Fan Sui appeared in front of Qin Wangji at the right time and presented the strategy of "distant friendship and close attack".

As a result, the national policy of the Qin State was changed, and the wise Qin Wang Ji chased the four nobles to support Fan Sui to ascend to the throne, and the general strategic direction of the Qin State changed across the board, no longer crossing the South Korea to fight the Zhao State as when he crossed the Wei State to fight the Qi State, but chose to fight South Korea first and take down the Shangdang County.

As long as the Qin State has Shangdang County, especially the Beishang Party, then the Qin army can attack Wu'an and Handan at any time through Fukou and Shandong, or attack Jinyang from the west, and fight wherever it wants.

As far as Zhao is concerned, if there is no Fukou as a road for the army, if Zhao wants to transfer troops from Jinyang and Handan, he will have to take the more northern and more remote Jingcheng, and the distance from Jingcheng is more than twice that of Fukou, so it is too late to provide timely support.

Therefore, the state of Zhao could allow the Beishang Party, which owned the Fukou Dynasty, to be owned by Korea, which was also part of the Three Jin Dynasty, but it could not tolerate the Qin state to obtain this land in any case.

Once the Qin State has the Beishang Party, then the Zhao State will only be passively beaten against the Qin State from now on, and there will be no room for active attack. This is determined by geographical conditions, and no one can change this unless they can move mountains and reclaim the sea.

So Zhao Guo had to fight, at least the Beishang Party must fight. Even if the timeline is pushed forward to the time when Feng Ting led the Shangdang County to descend Zhao and let the current Zhao Dan cross, then Zhao Dan must also take down the Beishang Party, otherwise Zhao Guo can't afford to play the game of chess to dominate the world!

This shows that any traverser who is interested in dominating the world must first pass the geography, otherwise pray that you can have a system to help you fight.

From this point of view, King Zhao Xiaocheng, who made the decision to accept Shangdang County in history, and Zhao Sheng, the Plains Jun who strongly advocated accepting Shangdang County, were really dizzy at that time? Not necessarily. Because nine years ago, in the battle of Yanhe, King Zhao Huiwen, the father of King Zhao Xiaocheng, also made the same choice when he faced the Qin army that was swarming from the south of Taihang Mountain, that is, - war!

Nine years have passed, and the core duo of the Qin State has changed from Qin Wangji and Wei Ran to Qin Wangji and Fan Sui, and Zhao has changed from Zhao Huiwen and Zhao Sheng to Zhao Xiaocheng and Zhao Sheng, but the determination and will of the two countries to compete for the party and even the entire Taihang Mountain have not changed.

This is the so-called centennial national policy, and it will never waver!

Any decision made with reference to the collective wisdom of the discussion will have its reasons, and if we simply summarize the performance of the Zhao leadership before and after the Battle of Changping in such a simple sentence as mediocrity or short-sightedness, it will inevitably seem biased, and overly despise the wisdom of the ancients, especially the leadership team that made the Zhao State so powerful.

Fighting for the world has always been a gamble, sometimes even if you get the right hand at the right time and choose stud may not be able to win, but if you don't stud you will definitely lose, so do you bet or not?

Zhao Xiaocheng and Zhao Sheng in history chose to gamble on this hand!

They did have a chance to succeed, because although the Qin State at that time was the strongest Qin State in history, the Zhao State was also the strongest Zhao State in history!

It's a pity that Zhao Xiaocheng and Zhao Sheng were still not skilled in the end, and lost to more powerful opponents Qin Wangji and Fan Sui, Qin won all the chips of Zhao Guo in one battle, kicked Zhao Guo out of the table, and became the ultimate winner.

But now, the same stud situation, now Zhao Dan with the knowledge brought by his traveler and the knowledge of history and the memory of the two generations of Zhao Dan and other factors, has successfully changed the situation of the gambling game, so that Zhao Guo has the upper hand for the first time in this gambling game where the two sides have not completely opened the hole cards.

As a traverser, Zhao Dan knew very well in his heart that Zhao Guo did not have as many chips as Qin Guo, so Qin Guo could still have chips to continue to bet with Zhao Guo if he lost this game, and if Zhao Guo lost, all the chips would be lost, and there would be no room for a turnaround.

However, because of Zhao Guo's advantage in the gambling game, this gambling game now has a chance to make a draw.

If you say it according to Lou Chang's words, then Qin and Zhao seek peace, each has losses, the result is that Zhao Guo won a small victory, Qin Guo's vitality was slightly lost, everyone was not injured, and the gambling game was reopened.

If you don't follow Lou Chang's words, then everyone will continue to gamble, the movements of Wei Yan and the two countries are undecided, and the future of the gambling game is unpredictable.

History has long been changed here, even with the blessing of the knowledge of the traverser, Zhao Dan can no longer predict what the final outcome of the gambling game will be, which is an extremely risky choice.

In the main hall of Longtai, all eyes were focused on Zhao Dan, waiting for the king of Zhao to make a final decision.

Zhao Dan fell silent, countless thoughts alternated in his mind, his face flickered with joy and sorrow, no one could know what this young King Zhao, who had only been on the throne for six years, was thinking.

After a long time, the young monarch of Zhao raised his head, his face was calm, there was no longer any entanglement or hesitation on his face, his eyes were clear, and his tone of voice was calm but unquestionable.

"Discord between the widows."
