The reason why Xu You didn't face Hulu Deva in Luoyang was because he received a military report from Zhu Zhi from Xiliang. After a bloody battle, the Liangzhou army and Yao Jin's Yuduowei finally captured Wuguan and entered Shangluo County (this place has nothing to do with Luoyang and belongs to present-day Shangluo County, Shaanxi).

Wuguan is stuck in the meeting place of the turbulent water flow of the Zhou River and Shaoxi Mountain, the road is south and the east moves, enters the blue field and passes the right danger, has the reputation of "one man guarding the base, a thousand people stagnation". The general of the guard is called Man Fogao, a Qiang man, good at war, and is deeply trusted by the old emperor Yao Yan, and is given the important task of guarding Longnan. Under his strict defense, the Liangzhou army knocked on the pass for more than ten days, with hundreds of casualties, and could not advance an inch, and Yu Duowei was not good at attacking the city, except for archery, it was even more unthinkable. In the end, Zhu Zhi's mastermind Zhu Yuanying offered a plan, wrote more than 1,000 letters of surrender and shot into the pass, which said that whoever sacrifices the head of the Manfo will be rewarded with tens of millions, and the marquis of the customs will be sealed, and the official will be promoted to the fourth grade.

Manfagou read the surrender letter and dismissed it, he was frank for the country, and his subordinates were the humerus brothers who had followed him for many years, in order to show that he was not suspicious, he did not confiscate all of them in accordance with military law, but allowed his subordinates to circulate them voluntarily. The so-called wealth is moving, who expected that there was a building owner named Liang Guoer, who was reprimanded by Manfogao some time ago, held a grudge, and took 500 men to climb over the wall at night, touched Manfogao's bedroom and cut off his head, and then set fire to the town guard's mansion.

The customs were in turmoil, Zhu Zhi successfully occupied Wuguan, and gave Liang Guoer and his subordinates a heavy reward according to the promise, and then Yao Jin went out and buried the bones of Manfogao with his own hands, and wept in public, praising his loyalty, sighing that he was confused by the traitor Yao Ji, so that there was today's catastrophe, and promised to treat Manfogao's descendants favorably after restoring the throne. This gesture moved the captured Xiliang defenders, and they took the initiative to ask to join the Imperial Duowei, willing to be the forerunner of Yao Jin.

Hearing that Wuguan was lost, the prestige of Manfogao was in a different place, the defenders of Shangluo County fled without a fight, and the Chu army marched along the valley of the Zhou River to Shang County, and was stationed on the spot after collecting the county soldiers.

Xiliang urgently sent Yao Xin, the general of the auxiliary state and the duke of Dongyuan, to lead 30,000 Ma Tun soldiers to Qingni to block the Liangzhou army. It was at this time that Zhu Zhi sent an urgent military report to Xu You, asking him to march as soon as possible and force Tongguan.

After getting the military report, Xu You knew that the situation was urgent, and if he didn't put pressure on Tongguan, Zhu Zhi would become a lone soldier who went deep into the enemy's territory, so that Yao Ji could ease his senses and mobilize heavy troops, for fear of unforeseen disasters.

So he summoned Ye Min, intending to leave him to stick to Luoyang, and asked him how many troops he needed, but Ye Min only said that 20,000 people were enough. Zuo Qi Xiao and others are not surprised, after all, they know a lot about Ye Min's ability, but the Jingzhou army is different, Tan Xiaozu is still reserved and measured, only when he met Xu You, he euphemistically proposed that the Chinese army could leave 20,000 people to assist the Cuiyu Army and the Chifeng Army to defend Luoyang, and the Tangtai Douxing was much more straightforward, and drank too much wine at the celebration banquet, and ridiculed Ye Min in front of many people.

Ye Min's temperament has always been to only do and not talk, drinking quietly, and he didn't hear the fart of the Douxing in Tai. Tan Xiaozu was scared enough, and secretly looked at Xu You's face on the main seat, and saw that he was not annoyed, so he was relieved. After the banquet was dismissed, he locked the Yutai Douxing in the room and whipped him ten times. When he woke up, he was half scared to death, trembling and went to Xu You to ask for guilt, but when he arrived at the Assassin's Mansion, he didn't see the main master, but Tan Zhuo met with him, smiled and comforted him, and said: "According to Cuidian, before the war, the speaker is not guilty." You are worried about Ye Min's dereliction of duty, so as not to implicate the three armies, which is a good thing. It's just that you can go directly to me in the future, or talk to General Chen, and don't talk too much after drinking, you know? ”

Compared with Tan Xiaozu's whipping, Tan Zhuo's attitude can be called like a spring breeze, and his attitude represents Xu You's attitude, which makes the Tantai Douxing, who is accustomed to the old military law, particularly unaccustomed, but also particularly touched, after going back, he directly cheekily went to Ming Jing of the Cuiyu Army to ask for this Cuidian, and saw that he couldn't sleep in the middle of the night, so he got up in his clothes and went to Xue Xuanmo, and said: "Jiushi, you said that if we also train according to this Cuidian, will we be able to train the strongest army in the world?" ”

Xue Xuanmo can eat since he was a child, his father joked that unless he produces nine stone rice per mu, he will starve to death in the future, and the average yield per mu of Chu at that time was about three stones, so it can be seen how much pressure the family has on having a son who can eat, so his small character is called nine stones.

However, Xue Xuanmo was ashamed of this small word, and only the Tangtai Douxing in the Jingzhou army dared to shout, listening to his noisy noise, Xue Xuanmo said angrily: "Don't let people sleep in the middle of the night, just for Cuidian?" Let me tell you, Cui Dian looks simple, but it is extremely complicated to practice, you really want to learn, wait for the Western Expedition to return to China, go and beg the general, let you enter the Tiger Hall for a while......"

"Tiger Hall ......" Yutai Douxing stabbed Xue Xuanmo's stomach and said blankly: "What kind of rare thing is that?" ”

Xue Xuanmo rolled his eyes and said, "When you are lucky enough to go around Qiantang, you will know what it is!" ”

"Really?" Tantai Douxing scratched his head and said, "When the Western Expedition is over, I will go to ask the general!" ”

After resting in Luoyang for three days, in the end, Xu You decided to respect Ye Min's opinion and gave him 20,000 people, the soldiers are not expensive, the Cuiyu Army and the Chifeng Army are like one, if you add a Chinese army, a group of arrogant soldiers and fierce generals, just like a spoonful of salt in the brain of sweet tofu, Ye Min is not good at commanding, but chaotic.

In addition, he gave 5,000 Chinese troops to Tangtai Douxing, led by him alone, to attack Hongnong County along the Luoshui, and after occupying it, they were stationed on the spot to protect the flank security of the line from Luoyang to Tongguan.

This is a clear transfer of the Tangtai Douxing out of the Jingzhou Military Group, embedding a nail into the Chinese Army Group, if it is usual, it is estimated that it will encounter a lot of resistance, but now Xu You is holding the power of a great victory, no one dares to object, and the credit of attacking Hongnong County is far less than the ambition of breaking Tongguan and Kechangan. Some people even snickered secretly, without the brave general of the Taitai Douxing, the chance of sharing it to their own head is much greater.

On 12 April, with Zuo Yan and Qi Xiao as the vanguard, they attacked Shaanxi County by land, and all counties along the way were expected to surrender to the wind. On 14 April, Xu You led the main force to march westward along the Yellow River by ship, and the army was very prosperous. Even in the east of Tongguan, the champion general Mi Po was standing at the head of the city, and the front team of the Guanchu army had arrived in front of him, but the rear team was not endless, stretching for dozens of miles, and he was shocked and discolored, and he couldn't speak for a long time.

That night, the camp was set up, and the handsome tent gathered to discuss the matter, and in view of the easy defense and difficult attack of Tongguan, Tan Xiaozu proposed to divide 30,000 troops to cross the river to the north and attack Pucheng. If Ke Pucheng, you may be able to bypass the Tongguan natural risk. Tan Zhuo objected and said: "Pucheng has guarded General Yin Zhao for many years, there are 10,000 elite soldiers, plus the city is strong and dangerous, if it can't be attacked for a long time, it will be useless in the war, and it will hurt morale, it is better to concentrate troops to conquer Tongguan, then Pucheng will fall." ”

Xu You asked He Wei's opinion, and He Wei said: "Tongguan is difficult to overcome, if you learn from Cao Cao's strategy of fighting horses and crossing the river west in Pucheng, although it is slightly risky and takes a long time, the chance of winning is greater, and the casualties will be reduced a lot." But this is the problem," he paused, looked back at Luoyang, and said with a worried face: "Receiving the report from the secret house, the 30,000 Chinese troops of the Northern Wei Dynasty are about to arrive on the north bank of the Yellow River, if Ye Min does not succeed in holding Luoyang, and our army is divided into two roads, as Tan Sima said, when Tongguan is not under and Pucheng is not over, it is attacked from behind by the Wei army's iron cavalry. ”

Zuo Yan also said: "It is imperative that we concentrate our forces to conquer Tongguan!" If the troops are divided into Pucheng, even if they can be broken, and then detour to Hexi, it is impossible to reach Weinan without more than a month. It's too late to be alone, and it's too risky! ”

In the final analysis, the victory or defeat of the battle of Tongguan actually lies in Luoyang, as long as Ye Min holds Luoyang, so that Xu You has no worries, no matter which strategy is adopted, he can deal with it calmly, why is it difficult to ride a tiger now, and he is at a loss?

In the end, Xu You still adopted Tan Zhuo's opinion, and early the next morning, Zhou Shiting and Cao Qing led the troops to attack. Tongguan occupies the advantage of the shape of victory, south of the Qinling Mountains, north of the Yellow River, to attack Tongguan, must first pass through the Yellow Lane Mountain, and then climb a section of the uplifted highland, there is the only hole that can be passed in the middle of the highland, only a few meters wide, called the five-mile secret door, the commanding heights on both sides are very easy to arrange ambushes. Zhou Shiting took the lead, with shield soldiers to resist the flying stones, Cao Qing used a strong bow to shoot a rain of arrows to suppress, and then formed 300 daredevils, with flying hooks to help the earth wall, nearly half of the death, only to take this highland, successfully climbed the Lintoe Plateau.

It's just that the distance between Lintoe Plateau and Tongguan is too close, and if the thunder cannon is placed, it will be destroyed by the defenders' stone cannons and bow and crossbow rockets before it can be deployed, so it can only take the conventional siege method and fill it with human lives.

This is the battle that Xu You is most reluctant to fight, but not every battle can be won with tricks and wisdom, and when it is time to fight, you must work hard, even if you pay a heavy price, you must move forward bravely. Only with such a vicious battle and the blood of countless people as purgatory, can we re-forge the unyielding bones of the Han people and the undefeated national soul!

(Recently, I have been reading the history of the war between the North and the South, and many times it is difficult to explain it.) For example, the Northern Zhou Dynasty and the Northern Qi Dynasty in the Battle of Pishan, the Northern Zhou Dynasty attacked Luoyang, took the lead, consciously strengthened the troops and horses, did not put the Northern Qi in their eyes, the pre-war plan said to cut off the Mengjin Ferry, but in fact to Luoyang, the Mengjin Ferry did not send troops to guard, so that the reinforcements of the Northern Qi Gao Changgong and Hu Luguang easily crossed the Yellow River, and took the Bishan as a stronghold, condescendingly, and defeated the Northern Zhou. ）

(There is also Liu Yu's defeat of Hou Qin, Tongguan such a dangerous place, Yao Shao is in power, 50,000 soldiers, but he refuses to hold on to the danger, he has to fight in the city, and he was defeated in a battle, and he didn't even want Tongguan, and retreated directly to Dingcheng.) I'm Cao, my brother Shuhan was forced out of the customs by Xuanzong's old fool, and you took the initiative to send ...... ）

(History is full of too many strange and accidental things, the sudden stupidity of the Ming Jun, the sudden muddy mistakes of the good generals, and the stupid things done by smart people, it is simply not too much.) Perhaps this is the true charm of history! ）
