"Report ~~~! General Ju, our brothers in the Meridian Valley noticed a large group of men in the valley yesterday night. I think it should be the army of the Shu thieves. ”

"Oh?! How many centaurs are there in the enemy army? ”

"This, in the middle of the night, is really hard to observe. Please forgive the general. ”

"Eh, brothers have worked hard, not guilty. But you have to strengthen the investigation, at least the approximate number of people on the side of the Shu thieves, and estimate who is leading the army, so that the general can write a report to Da Sima. Otherwise, with Da Sima's temper, it would have been inevitable to be reprimanded. ”

"No! Thank you for your understanding. I'll do my best to get to the bottom of this. ”

"Well, don't spread the news first, lest the army be in a commotion. Ben would have been secretly working on defense arrangements. ”

"No!"

The Meridian Valley is more than 300 kilometers long. Of the six realms of the Qinling Mountains, the other five were once used by military strategists as passages for slow marches or sneak attacks. As for the path of Meridian Valley, it has been used by countless military experts as a military plan, but none of them have ever succeeded.

The reason for this is that, in addition to the steep roads like the other five roads, the most troublesome thing about the Meridian Valley is that it is a passage where the north-south airflow meets, which leads to very frequent climate change.

In 230 AD, Cao Zhen, the general of Cao Wei, felt that his time was running out, so he insisted on taking the risk of cutting down Shu. The chosen route of march was this Meridian Valley. As a result, soon after entering, it encountered heavy rain, such as the plank road was damaged. After a month, half of the Meridian Valley was not reached, and finally the army had to retreat.

But this daunting canyon became a super ancient highway in the Tang Dynasty: Yuhuan wanted to eat lychees, and the shelf life of lychees was extremely short. Tang Xuanzong spent great manpower and material resources to strengthen and renovate the Meridian Valley. Pave the entire canyon floor with bluestone. It ensures that the lychees shipped from today's Fuling in Chongqing only take seven days to arrive in Chang'an (incidentally, today, from Chongqing to Xi'an, self-driving, the whole high-speed, more than two drivers take turns to drive, minimize the rest time in the service area, and generally take 10~12 hours - mainly when crossing the Qinling Mountains, the bridge-tunnel ratio is too high, and the speed limit is very strict).

Therefore, the transportation conditions of the Meridian Valley, even in ancient times, as long as the national strength was sufficient and the determination was strong enough, it could be transformed into a very favorable passage for the army.

From the beginning of the agreement between Guan Yi and Sima Wang on the monopoly of high liquor in 264, the Shu Han side strengthened the various passages in the Qinling Mountains in the name of "transporting materials to Chang'an as soon as possible". The main one is the Praise Slope Road, the Meridian Valley, which is also half-repaired: it can only be half. Unlike the exit of the Bao Slope Road in Wuzhangyuan, which is still hundreds of miles away from Chang'an, the exit at the north end of the Meridian Valley is more than 40 miles south of the southern city wall of Chang'an, so Sima Wang only allows the Shu Han side to make up for the southern end of the Meridian Valley, and it is not allowed to be reinforced after the middle line.

However, for Shu Han, who has cement, it is really troublesome for a road to be unreinforced in advance, but we have prefabricated slabs! And this thing doesn't have to be carried with the army for long distances, as long as there is cement, it can be made everywhere you go!

On July 16, Jiang Wei led his army into the Meridian Valley from the south.

On the twentieth, the main force of Shu Han had already traveled half of the Meridian Valley, and then they were inevitably discovered by the scouts of the Jin army.

On the 23rd, the first report of the Jin army scout team was sent to the desk of the guard general Ju'an at the northern end of the Meridian Valley. Then he was temporarily suppressed by Ju'an with unknown information.

On the 25th, the detailed information of the Jin army scouts was sent to the desk of Ju'an.

"General, subordinates and others have found out. The Shu thieves marched into the Meridian Valley this time, and it was a large corps. Judging by the length of its ranks, there are at least 50,000 people! The banner of the great general Jiang has been clearly seen. I think it should be Jiang Wei, the chief of the Shu thieves, leading the troops! ”

"Hey~~~ Don't go down the slope, why did these guys come to Ben General's side? Come here, beat the drum of the generals, and summon the officers above the marquis of the army to come to the big tent to discuss matters! ”

"No!"

Although the Luoyang Chinese Army has never performed well on the battlefield due to the failure of the leadership of this session. But in the end, it is the elite formed by gathering the essence of the world, and the area of the camp of 5,000 people is not very large, so as soon as the drum of Ju'an's gathering generals beats, in less than a quarter of an hour, all the middle-level officers are all there.

"Ladies and gentlemen, this is the situation right now. What this general meant was that on the one hand, everyone would go down and gather their troops and defend according to the fortifications we had built at Taniguchi in advance. On the other hand, the general quickly sent light cavalry to Chang'an to report the emergency! After Ju An, who was sitting on the main seat and calmly gave orders, said this, he looked at the officers below with solemn faces, and smiled lightly: "Don't be nervous, Ben Jiang has been under Jiang Wei for many years in the past, and his ability to flirt with this is very clear." Based on the current strength of the enemy and our own, unless it rains heavily again in the Meridian Valley, we will not be able to face Jiang Wei directly. However, before we came here, Da Sima also said that he only asked us to hold out for five days, and within five days, he would definitely come to support. Besides, how close we are to Chang'an, it's only more than 40 miles. So in three days at most, reinforcements from Chang'an will arrive. Therefore, Ann is here to ask you, no matter what, you must hold on for three days! When the three days come, if the reinforcements do not arrive, Ben will lead you to retreat. When the time comes, all the blame will be on the will. ”

As soon as Ju'an said this, some of the Jin army generals breathed a sigh of relief. But there were also some generals who frowned: "General, the country is in crisis, so it doesn't matter what the responsibility is." No matter when Da Sima's side sends reinforcements, since we have been assigned here to guard the mouth of the Meridian Valley. Then the enemy is coming, and the only way to fight to the death is to fight! ”

"Good! That's how heroic it is! Everyone, take your seats. Ben will immediately write a letter to the prison army in Chang'an asking for help! ”

"No!"

Of course, Ju'an sent a messenger for help, after all, the camp of 5,000 people was so large, and the officers and soldiers under his command were mainly from the Luoyang Chinese army. If you don't do it enough, you're looking for death. The only trick he could do was to send two messengers at the same time, one of whom was his cronies.

On the other side, Jiang Wei's team.

From the beginning of crossing the middle line of the Meridian Valley, the road becomes difficult, and from time to time there are rockfalls of different sizes speeding on the towering mountains on both sides of the canyon, and the unlucky vital parts are next to each other, and they cannot be seriously injured or even killed directly on the spot.

These are nothing, and the most important thing is that the speed of the wind and clouds in the Meridian Valley is extremely fast. Just now the sun was still shining, and after a while, a dark cloud floated in, and the people below had not had time to take out the rain gear, and they had already been poured into the cold.

It was also the 25th, late at night, when the Shu Han army finished the day's rush and wanted to stop for a while. As soon as the bonfire was lit, there was a torrential rain accompanied by frequent thunder and lightning. The main force of the entire Jiang Wei team, in the midsummer night, was trembling with huge raindrops.

"General Qiqi, the scouts ahead have found out, and now we are still more than sixty miles away from the valley mouth at the north end, because of the heavy rain just now, there is a small section of plank road in front of which has been smashed by falling rocks on the top of the mountain. The former army is digging up the rubble and then rebuilding the passage with prefabricated slabs...... If there is no rain in the second half of the night, it should be repaired early tomorrow morning. ”

In the end, he is old, at the bottom of this deep valley, after suffering a cold rain, Jiang Wei's body couldn't help but tremble slightly: "Good, brothers have worked hard." ”

After the scouts retreated, Jiang Wei turned around and smiled at the middle-aged and elderly generals who were also wet: "There are still sixty miles, let everyone hurry up and rekindle the fire." When the firewood is wet, ignite the oil directly. Be sure to dry your clothes and bedding before you can sleep. Tomorrow we will march in a hurry to attack Taniguchi tomorrow! ”

"No!"

……

One night without words, the next day, July 26.

After the hard work of the Shu Han engineering team, the plank road was quickly restored. Then Jiang Wei put the brigade behind, personally led the five thousand commando generals to march forward, and approached the Jin army's Dazhai at the exit of the north end of the Meridian Valley at about three quarters (half past six in the afternoon) on this day.

It was the middle of summer, and it was getting very late. So the sky should still be bright at this time. But the weather in Meridian Valley was never elusive, and at this time, there was another dense thunderclap, and then the raindrops the size of beans fluttered down again.

The heavy rain at this time was not a trouble but an excellent help for the Han army. Under the cover of dense rain, the Han army was close to more than 20 meters in front of the Jin army's Dazhai before being discovered by the Jin army's lookout post.

"Enemy attack! The Shu thief is coming! ”

"Archers?!"

"All soldiers on the wall!"

"Hurry up and report to the general!"

The Jin army's response was extremely fast, and the middle and low-ranking officers quickly organized themselves. Of course, they did not forget the humility of the upper and lower levels, and they all subconsciously wanted to inform the supreme commander of their own side here.

And where is Ju'an at this time?

He led more than 20 of his cronies who had followed him for many years, and stood guard at the door of the stockade!

On July 26, 268, many years of preparation, new materials, and internal help. Jiang Wei led the army to break through the Meridian Valley!
