There are six main roads from Hanchuan County to Guanzhong, namely Chencang Road, Bao Shue Road, Fu Luo Road, Meridian Road, Kugu Road, and Wuguan Road. Among the six avenues connecting Guanzhong, Meridian Valley is undoubtedly the most precipitous. More than once in history, someone has proposed to smuggle Meridian Valley, but unfortunately, no one has ever succeeded.

The Meridian Valley starts from Duling, passes through the Qinling Mountains and reaches Hanchuan, with a total length of more than 600 miles. It was opened in the Qin Dynasty, and the first time it appeared on the stage of history was in the late Qin and early Han dynasties, when it was the period of "Liu Xiang Rivalry", Liu Bang was forced to go to Hanzhong to take up the position of King of Han, and it was from the Meridian Valley that the difficulty of the road inspired the determination of the Han soldiers to fight against Xiang Yu. In the end, they fought back to Guanzhong and seized the world.

In the history of the Three Kingdoms, Wei Yan, the general of Shu State, once suggested that he take Chang'an City directly from the Meridian Valley, but was vetoed by Zhuge Liang, who had always been cautious.

During the Eastern Jin Dynasty, the general Hengwen tried to smuggle across the Meridian Valley to attack the former Qin, but was ambushed by the Qin army before he left the valley.

During the Chongzhen period of the Ming Dynasty, Gao Yingxiang, the king of Chuang, also tried to smuggle across the Meridian Valley, but in the face of the harsh weather and steep roads in the Meridian Valley, Gao Yingxiang's tens of thousands of troops were already sleepy and lacking in horses and horses after only half the journey, and the material losses were serious.

In the end, Gao Yingxiang's tens of thousands of troops encountered the 20,000 main forces of the Ming general Sun Chuanting in the area of Heishuiyu in the Meridian Valley, and the two sides fought fiercely for four days, and Gao Yingxiang, the king of the world for seven years, was captured, ending his life.

It was precisely because of the steepness and difficulty of the road in the Meridian Valley that it was not until the Sui army was cornered that Li Mi proposed a plan to Long Zhi to attack Chang'an. In fact, it's a gamble. If they win, they will have made a miraculous achievement. But if you lose, there is only one end - death!

I don't know if it's God's favor, Long Zhi and Li Mi didn't suffer heavy rain like Gao Yingxiang in history, plus Long Zhi and Li Mi were determined to break the cauldron this time, and threw away all the unneeded baggage and burned it, so the Sui army's marching speed was not known how many times faster than Gao Yingxiang.

。。。。。。。。。。

Eight days later, Ryuji finally set foot on the Guanzhong Plain, looking at the endless flat field in front of him, Ryuji's eyes burst with infinite excitement.

"General Long, we're finally here!"

The bright light armor that Sheng Yanshi wore was now tattered, and he was dressed as a beggar, but it couldn't hide the joy he felt when he spoke.

"Yes! We're finally out, but some of us can't get out again! ”

Long Zhi muttered, turned his head and glanced at the difficult valley road behind him, and the corners of his eyes suddenly became a little moist.

In order to pass through this valley road as quickly as possible, the Sui army marched almost day and night for these eight days.

The roads in the Meridian Valley are steep, and even during the day, there will be soldiers who occasionally stumble and fall, and at night, because of the night, the casualties are even greater. After eight days of marching, at least 3,000 soldiers were laid to rest in this valley.

But there is no way to do it, Li Shiji and Li Longji are not stupid, after discovering that the Sui army suddenly lost its trace, they can soon think about where the Sui army went. Therefore, Ryuji could only seize all the time to speed up the march. Otherwise, if Li Longji and Li Shiji are allowed to rush back to Guanzhong first, then everything will be over!

"General, we don't have time to be sad now, we must set off as soon as possible to take Chang'an. Otherwise, all these brothers in the valley would have died in vain! Li Mi, who was originally a Dao bone fairy style, also became embarrassed at this moment, and the only thing that remained unchanged was his calm mind.

"The military advisor is right!" Long Zhi nodded slowly, picked up his sword and got on his horse, staring at the elite of the Sui army in front of him, who had already been completely faceless, and said loudly: "Soldiers, tell me, what are we marching for so many days for?" What was the sacrifice of so many brothers? ”

"Chang'an, it's to take Chang'an City!"

At first, there were only a few voices, but gradually the voices converged, and in the end, the more than 16,000 soldiers roared out in unison.

"That's right, it's to take Chang'an City!"

The long knife in Long Zhi's hand was raised upward, and he said loudly: "Now, Chang'an City is close at hand, and success or failure is here!" Take out the last of your strength, plant the battle flag of our Great Sui on the head of Chang'an, and pay tribute to those dead soldiers. ”

The morale of the Sui soldiers was high, and they raised their arms and shouted: "Victory!" Win! ”

"Kill, target Chang'an City!" Ryuji raised the long knife in his hand and rushed forward.

。。。。。。。。。。

Since the founding of the Li Tang Dynasty, Chang'an City has never been harassed by war. The long period of tranquility paralyzed Li Tang Junchen, and as the Tang army's various fronts tightened, the Tang army stationed in Chang'an was constantly withdrawn. Nowadays, in addition to the 5,000 Imperial Forest Army in Chang'an City, there are less than 3,000 county soldiers.

Hanchuan County is adjacent to Guanzhong, and the Sui army is also clear about the garrison in Chang'an. Since ancient times, the besiegers have surrounded it three times, attacked it five times, and pulled it out ten times.

At present, the strength of the Sui army is only more than 16,000 people, and the Chang'an garrison has more than 8,000 people. Therefore, Li Micai suggested that Long Zhi immediately send troops, because the only chance to take Chang'an was to take advantage of Chang'an's unknowledge of their existence to suddenly attack and catch Li Tang off guard. Otherwise, once the gates are closed, it's all over.

Long Zhi has led the army for many years, and he is naturally very clear about this truth, so after being reminded by Li Yu, he also couldn't take pity on the physical strength of the soldiers, and led the army all the way to Chang'an.

Gradually, the outline of the city wall of Chang'an City had come into Long Zhi's eyes, and Long Zhi couldn't help but lift his spirits, slammed the horse's belly, and shouted loudly: "Brothers, kill into Chang'an City and capture Li Yuan's old thief alive!" ”

"Kill! Kill! Kill! ”

More than 16,000 Sui soldiers shouted loudly, brandished swords and spears with cold light in their hands, trampled on dust, like an iron-black torrent, and rushed towards Chang'an City with murderous energy.

"Ding Dong, it has been detected that Ryuji has entered a state of fearlessness, force +5, base force 95, and the current force has risen to 100."

Long Zhi took the lead, and the horse flew over the moat, and the Tang military captain stationed at the city gate was so frightened that he was stunned on the spot, only to hear a loud roar in his ears, and the cold light appeared in front of him, and he was immediately separated.

"Enemy attack, enemy attack!"

The Tang soldiers guarding the city gate were the same as the high-ranking Tang Dynasty, and the long-term peace had paralyzed their will, and this sudden attack made them chaotic in an instant, and they didn't even close the city gate, so they scattered and fled.
