Hangu Guanxi according to the plateau, east of the stream, south of the Qinling Mountains, north of the Yellow River, is the east to Luoyang, west to the throat of Chang'an, known as "the sky opens the Hangu strong pass, the valley of the dust to the north sky", "the twin peaks towering beside the river, since ancient times Hangu a battlefield", Zhou Shenliang King three years, Chu Huai Wang raised the division of the six countries to cut Qin, Qin according to the natural danger of the Han Valley, so that the army of the six countries "ambush millions of corpses, bleeding and drifting", it is really a place where soldiers must fight.

Luoyang, the capital of the Han Dynasty, once had two barriers, one is Hangu, the other is the tiger prison, the tiger prison is currently in the hands of Dayan, guarded by Zhang Liao, and the tiger looks at the Central Plains, in fact, it also represents Luoyang in the hands of Yuan Xi, but Luoyang at this time is not even as good as a certain county government in Dayan, because the princes of the Eighteenth Road asked for Dong, after breaking the tiger prison, the allied army was like a bamboo, Dong Zhuo coerced the Son of Heaven, civil and military officials to move the capital westward, and went straight to Chang'an, in order not to leave any materials and equipment for the allies, Dong Zhuo ordered: Anything that cannot be taken away will be burned, So not only burned the palace, even all the official offices and houses in Luoyang, but also burned all the fire, since the Eastern Han Dynasty in 25 AD, the Han Guang Emperor Liu Xiuding began to operate Luoyang, the luxurious and wealthy capital Luoyang, so it was burned by Dong Zhuo, Luoyang has since become a scorched earth, the surrounding two hundred miles of houses are all destroyed, chickens and dogs are not left, so occupy Luoyang, and get the world, has long become a joke, Luoyang was burned, but also with the Han Dynasty official gas has been exhausted.

However, although Luoyang goes, Hangu Pass and Tiger Prison Pass still have a huge strategic role.

In the first battle of Guandu that year, in order to force Yuan Xi back, Cao Cao gave Hangu Pass and most of the northern passes to Han Sui and Ma Teng, forming the strongest alliance and retaining a chance to breathe.

And if Dayan wants to completely recover Xiliang, he must also take Hangu Pass, maybe some people wonder why they don't kill it directly from the grassland, here they have to mention the problem of logistics, the grassland is vast, the weather is weird, the terrain is complex, the desert, and the swamps are countless, so Yuan Xi wants to build a stable city, but it still takes a lot of time for the city to be stable, so as a strange soldier, it is still possible, but once a long-term war breaks out, the transportation of grain and grass will become a great obstacle, and any war, the soldiers and horses have not moved, and the grain and grass go first, Once there is a problem with grain and grass, even a million troops will suffer a crushing defeat, which was really the case in the battle of Guandu back then.

And if Hangu Pass is taken, Dayan's iron army can march into Guanzhong, and there will be no obstacles to grain and grass, and the army can run rampant for thousands of miles.

At this time, Da Yan and Cao Cao did not pay attention to the question of who won and who lost in the Xiliang Civil War, and the key was in Hangu Pass.

In Yecheng, in the inner room of the Privy Council, Zhang Nan said with a serious face to Li Ru: "Zuo Xiang, I just got the news that Cao Cao sent Guan Yu to command 50,000 troops and secretly stationed in Chang'an."

I saw that in addition to Li Ru in the Privy Council, Tian Feng, Han Yan, Zhuge Liang, Pang Tong, Sima Yi, Xin Ping and other important ministers were also there.

"Cao Cao also wants Hangu," Pang Tong sneered.

"Ma Chao has successively defeated Han Sui in Beidi, Tianshui, and Longxi, and it seems that he has gained the upper hand, but if you check carefully, you will find that Han Sui is luring the enemy to go deeper, looking for an opportunity to annihilate Ma Chao's 20,000 Xiliang Iron Cavalry" Sima Yi said solemnly.

"Ma Chao is full of anger, just want to kill Han Sui, all the way to the past, without stopping, the soldiers must be tired, the art of war is cloudy, one drum, then decline, three and exhaustion, Liang feels that Han Sui will soon counterattack, Ma Chao will be defeated" Zhuge Liang affirmed.

"If Ma Chao is defeated, he will inevitably retreat to Hangu Pass and ask for assistance, Cao Cao's 50,000 troops are stationed in Chang'an, just to break Ma Chao's idea of asking for help from my Dayan, do you want to immediately order General Zhang Liao to command his subordinates and attack Chang'an to the west" Han Yan suggested.

"No, if this happens, Ma Chao must be vigilant, this matter must be voluntary, in addition, although Hangu is important, but the tiger prison must not be lost, the king made it clear that without his order, General Zhang Liao must not be mobilized" Tian Feng immediately said.

"Cao Cao must have sent someone to send a letter to Hangu Pass, and even has the idea of directly annexing Hangu Pass, now it depends on whether Ma Chao keeps his promise to the king, or for the foundation of Xiliang and his own rights in Bo" Li Ru said solemnly, after Ma Chao sent his sister to arrive, he had chatted with Yuan Xi for a long time, Yuan Xi promised him that if there was an accident in Xiliang in the future, he was desperate, and he was willing to canonize Ma Chao's brother-in-law as the general of Dayan Shenwei and form the Seventh Army, ranking among the commanders of Dayan.

"The promise is not very reliable, since Cao Cao made a move, my Dayan must not let it go, otherwise I am afraid of accidents" Sima Yi frowned.

Zhuge Liang smiled slightly and said: "Actually, my Dayan still has a move, which is also the reason why the king married the second daughter of Xiliang back then."

"Ma Guifei" Pang Tong said immediately, but soon his face became a little embarrassed, and said: "I heard that after Ma Guifei knew that the Ma family was destroyed, she was grief-stricken and burst into tears. ”

"Yes, definitely, at this time Ma Guifei is really the most vulnerable time, the reason why the king left is because he has affection for Ma Guifei, he can't speak at this time, and the king's departure makes Ma Guifei need someone more to protect her, and this person is her eldest brother Ma Chao, Cao Cao moves with power, I Da Yan moves with affection, as long as Ma Guifei can repair a book and hand it over to Ma Chao, it will inevitably have a huge impact" Zhuge Liang said confidently.

"So-and-so immediately go to see the queen and the Marquis of Runan" Hearing this, Tian Feng immediately said.

"Prime Minister Zuo, give more promises, the king will not object, as long as Xiliang is in hand, the Central Plains will be determined, and the dynasty will be successful" Seeing this scene, Li Ru immediately reminded.

"Right Prime Minister is relieved" Tian Feng walked out of the Privy Council with a serious face.

"General Staff Xin, you immediately send an order to the Fourth Army Corps, inform Yuan Zhi, let you get ready, once Hangu Pass is in hand, immediately sweep the entire Xiliang, don't delay for a moment" Li Ru ordered.

"No," Xin commented.

"Zuo Xiang, in addition, there is actually another question, if Ma Chao really surrenders, then what should Concubine Han do? The contradiction between Ma and Han is impossible to reconcile, a choice must be made, and I heard that Han Guifei is very much loved by the Queen Mother," Sima Yi suddenly said seriously.

Li Ru was stunned for a while, and after being silent for a while, he said: "If Hangu Pass really succeeds, it will immediately play the king, the king is talented and strategic, and he will have a decision."

"No," the crowd replied.

Not long after, in a gorgeous palace in the harem, I saw Han Mengtong, who was dressed nobly and had a soft appearance, looking at an attendant in front of him with a worried face.

"Did you really see Zuo Xiang and Marquis Runan, entering the queen's bedroom," Han Mengtong asked again.

"Yes, your concubine"

"I knew that Hanguguan was still in the hands of Ma Chao, and it must be a huge disaster" Han Mengtong remembered a letter sent by Xiliang a few days ago, her father asked her to use the identity of a noble concubine to let the king support him to occupy Xiliang, she asked the person who sent the letter at that time, and learned that Hanguguan was not in the hands of her father, so she knew that something would definitely go wrong.

"Miss, what should I do?"

Han Mengtong immediately stood up and said solemnly: "Zuo Xiang, they definitely want to use Ma Yunlu to get Hangu Pass and open the Xiliang Gate, which is no longer stoppable, plus this palace, as the concubine of Dayan, it is impossible to stop the king's hegemony of dominating the world, the cold palace is to deter us, but we must save my father, brother, and their lives, because only if they are there, this palace can be stable."

"Go to the Longevity Palace immediately, the palace wants to meet the Queen Mother" Han Mengtong rushed out in a hurry, and a battle in the inner court also began.
