Gu Xun was naturally very satisfied with the result. Although what Yan Dan told was just some anecdotes buried in history, and he did not know the true or false geometry, it still had some reference significance. Moreover, the real big head of this transaction was not there in the first place.
This.
It’s just an insignificant addition, how much is enough?
In contrast, Yan Dan's mood was not so good.
He was forced to pay the reward, but Gu Xun told him that he had to sneak away first and could only send his subordinates... Although the guaranteed conditions were very generous, he still felt a little unsure.
No matter what, it was a done deal, and Yan Dan had no choice but to force himself to settle down.
The matter had been discussed, and Gu Xun was about to leave, but before leaving, he still asked one more question he had in mind:
"Your Highness Yan Dan, I'm very curious, how did you know the last piece of information?"
Yan Dan was silent for a moment and then replied, "As the National Master said just now, it's just a coincidence, but I can guarantee that the probability that the news is wrong is very low."
"Okay, a coincidence is a coincidence." Gu Xun smiled and accepted Yan Dan's statement without asking any questions, turned around and left.
………………
Three days later, Yan Dan's plan has not yet begun, but Gu Xun has made all preparations and is about to leave for Shu County.
But he didn't go alone, there was a follower - not Concubine Yan, but Zhang Han.
That's right, it's Zhang Han.
It is equivalent to Yingzheng sending a supervisor to watch over him. He does not have much power. He is just a human monitor responsible for reporting afterward.
After Gu Xun thought about it for a while, he felt that it was harmless and he could follow if he wanted to, so they became the current two-person team.
On the official road to the west of Xianyang City, Gu Xun and Zhang Han were riding their horses slowly.
They want to go to Yongdi, then go south along the old road, cross the Bao River, pass through Nanzheng (ie Hanzhong), turn around Shiniu Road, Jiameng Pass, Jiange Zitong, and finally reach the Sichuan-Sichuan Plain, where Shu County governs Chengdu.
The road to Shu is as difficult as climbing to the sky!!
When Li Taibai recited this poem, thousands of years had passed since this era. The road to Shu was difficult to cross at that time, and it is naturally even more difficult now.
From Guanzhong to Shuzhong, it is roughly divided into three areas, namely the Guanzhong Plain, the Hanzhong Plain, and the Chengdu Plain. There are two rugged and difficult mountainous areas in the middle, namely the north and south mountain sections of the Qinling Mountains and Daba Mountain.
The two sections of the mountain road are 600 miles long in total. The road is full of difficulties and obstacles, cliffs, cliffs, rapids, and canyons. In the true sense, even birds have difficulty flying across it, not to mention that the main means of transportation today are still two-legged and horses.
Human.
Of course, if you want to enter Shu, you don't have to walk through these six hundred miles of mountain roads. Some... can be said to be shortcuts, but shortcuts are also dangerous routes, such as the one Gu Xun and Zhang Han are going to take.
The route that Zhang Yi and Sima took to destroy Bashu by mistake in the past.
This is a suitable route, but it is also a road full of dangers. Not only are the mountains and mountains dangerous, but more importantly, the people of Shu can easily ambush the attacking troops along the entire route. With the natural dangers and man-made disasters, even if there are
Millions of soldiers are helpless, so even a country as strong as Qin can only hope and sigh.
Since the reign of Duke Li of Qin more than two hundred years ago, Qin and Shu have been fighting endlessly for the land of Nanzheng. Both sides have come and gone. Even after Shang Yang's reform, Qin's national power became increasingly prosperous, but it still could not completely suppress it.
Shu Kingdom and Nanzheng changed hands several times again.
Until the tenth year of the reign of King Huiwen of Qin, the son of Duke Xiao, civil war broke out among the four kingdoms of Bashu, Shu, Ba, Chong and Ju. Ba annexed Chong, and then Shu destroyed Ba and stared at the final Ju. The State of Ju was unwilling to sit back and wait for death, but was unable to contend with the State of Shu on its own. In the end, it made a foolish but helpless choice to introduce foreign aid.
It can be said that all relevant historical lessons from ancient and modern times at home and abroad are teaching us that people who do this will not end well, but there is no way, no matter what, they will die, but there is always a glimmer of hope if you give it a try.
So the State of Ju attacked the State of Qin, which was at its peak at the time, but when the states in Shandong joined forces to resist Qin, and Yiqu in the west rebelled and attacked, Qin was attacked from both sides and urgently needed to break the situation.
Under Sima Cuo's urging, King Huiwen decided to capture the Bashu land to ease the situation.
Under the deliberate permission of the State of Ju, the Qin State's army was able to pass through the Stone Cow Road unharmed and headed straight for the first pass in Sichuan and Shu, Jiameng Pass.
This is a dangerous pass, no less impressive than Cui Wei's sword pavilion. It can be said that one man can handle the pass, and no one can open it.
However, there was a huge disparity in strength between Qin and Shu. The Qin army did not lose much combat power during the march because of Ju's release. In addition, Shu had been in a corner for many years and had insufficient awareness of the military strength of the powerful Central Plains countries. The king of Shu was arrogant and arrogant.
The armament was also completely crushed. With the superposition of several aspects, the Shu army was defeated as expected and lost Jiameng Pass.
At the same time, the Shu army suffered heavy losses due to this defeat and was unable to gather enough troops to resist the Qin army again. Qin easily swept away the entire Sichuan and Shu.
After the Shu Kingdom was destroyed, the Qin army naturally turned its spearhead and engulfed the Ju Kingdom, completely occupying the Bashu region that had been separated from the Central Plains for thousands of years.
In this era of cold weapon warfare, food is everything, and the capture of Bashu allowed the Qin State to obtain two extremely important grain-producing areas, the Hanzhong Plain and the Chengdu Plain.
The most fundamental material basis for the Qin State to be able to compete with the Shandong states is that it occupies the Guanzhong Plain, which is known as the "Eight Hundred Miles of Qinchuan". The Hanzhong Plain plus the Chengdu Plain is equivalent to half of the "Eight Hundred Miles of Qinchuan".
In other words, it is equivalent to the upper limit of Qin's basic national power directly increasing by 50%.
Of course, this is just a general statement and cannot be calculated in such a simple and straightforward manner, but it is enough to reflect the importance of the land of Bashu to the Qin State.
It is precisely because of this that even though Shu rebels every year, Qin can only take the trouble to spend a lot of manpower and material resources to suppress the rebellion again and again.
At the time when Gu Xun and Zhang Han set off for Sichuan and Shu, a rebellion happened in Shu County.
Although the scale was not large, it could be easily suppressed by relying on the troops stationed in Shu County. Ying Zheng still took the opportunity to mobilize a force and sent it to central Shu.
On the way, Zhang Han couldn't help but look to Gu Xun and asked, "Master, why are we walking so slowly?"
Gu Xun took him and drove the horse to stroll on the road as if on an outing. The speed... was probably not as fast as him getting off the horse and stretching his legs.
An hour had passed, and he had not gone a few miles away. If he found a high place to look over, he might still be able to see some of the palace walls of Xianyang.
Gu Xun turned his face and glanced at him sideways, and asked in a weird voice, "Why, are you in a hurry?"
"Uh... No, the general is just worried that he will miss important matters of the Imperial Master." Zhang Han choked for a moment when he said this, lowered his head and explained carefully.
"If you're not in a hurry, don't make things difficult. I walk slowly for my own reasons." Gu Xun shook the reins and replied perfunctorily.
