Seven thousand white-robed people climbed the city, white-clothed and silver-armored like snow, repelled the enemy soldiers who landed in the city, and recaptured the city walls and urn cities!

Because of the arrival of the general Chu Zimou's reinforcements, the morale of the defenders of Yumen Pass rose greatly, and the Mongolian army and the servant army withdrew to the rear like the waves of the ebbing tide.

The originally crumbling Yumen Pass is held on again!

Within one day, the attack and defense of the Battle of Yumen Pass changed again and again, and it was not until Chutian led reinforcements that the Mongol army retreated.

Xu Fengnian was almost sitting on the city bricks, panting.

The temporary withdrawal of the Mongol Empire's army allowed Xu Fengnian to finally take a good breath, otherwise with Temujin's strength, maybe Yumen Pass would really be captured by the Mongol cavalry.

He looked around, all the Han army and army guarding Yumen Pass were almost crippled in the tragic battle, Temujin and Ali Hague's army and servant army were killed 100,000, and near Yumen Pass, there was a sea of corpses and blood.

Zhang Xiu and hundreds of Xiliang soldiers recaptured the body of his father Zhang Ji, and they were silent.

In this battle, Zhang Ji, the general sent by Lao Qin to aid Yumen Pass and the general of Dong Zhuo's Xiliang Army, was killed in battle, and Zhang Xiu gritted his teeth at it.

"The Roman legions have killed my father, and he must pay the price for it!"

Zhang Xiu still had a hatred for the Roman legions.

The Roman legions were all high-level troops, and Zhang Ji invaded the Roman legions and was killed by the Roman legions.

Xu Fengnian just shook his head at what happened to Zhang Xiu.

In the Battle of Yumen Pass, there were countless dead and wounded generals, and Zhang Ji was just one of them.

Great wars will only get more and more fierce, and even if the whole army is wiped out, it is not uncommon.

"Why did the shouting stop? Could it be that the Mongol army has already invaded the pass? ”

The injured Zhang He hugged his shoulder, which was burned by the fire, and tried to get up to fight, but was stopped by his old acquaintance Ju Yi: "Don't worry, the lord's reinforcements are coming, we don't have to continue fighting." ”

"It turned out that the lord had arrived, so it seems that the Mongol army will most likely retreat."

Zhang He heard that Chutian was coming, so he lay down with peace of mind.

At present, various abilities are superimposed, and the only person who is qualified to play cavalry with Temujin is Chu Tian.

The Mongol army did exactly what Zhang He had inferred, and chose to withdraw.

Temujin was still hesitating whether to fight Chu Tian in a decisive battle.

Temujin also knew that Chutian was the largest prince of the Han Empire, and if the decisive battle with Chutian was lost, then the end of the Mongol Empire would soon come.

According to Zhang He's inference, Temujin was still accumulating strength, so he had avoided confronting Chu Tian head-on.

"Go and meet Chu Zimou."

After Xu Fengnian gasped for breath, he finally got up and went to see Chutian with Ma Teng, Han Sui, Feng Yi, Xie Ai and others.

If it weren't for the arrival of Chutian's reinforcements, perhaps Yumen Pass would have become a ruin by now.

Under the offensive of the Mongol cavalry, there were not many people who could hold the Yumen Pass, but this group did it!

When Xu Fengnian got up, he almost fell because of his loss of strength, but Wang Yanzhang held Xu Fengnian with one hand, and Xu Fengnian did not fall.

Chutian sent a white-robed army to take the lead and relieve the siege of Yumen Pass.

After the white-robed army dismounted, they could become light infantry and kill the enemy on the city wall, which was not inferior to the high-level light infantry.

Compared with heavy infantry, light infantry has a lower level of protection, but it is faster and has a slower rate of physical exertion, making it suitable for continuous combat.

After the Mongol army retreated, Chu Tian entered the Yumen Pass, and found that the houses in the Yumen Pass had been burned in half, and it was a mess, and the city walls and nearby houses were emitting billowing black smoke, apparently after an extremely tragic battle.

The dead, tens of thousands.

Collapsed walls, houses, broken battle flags, broken spears, torn armor......

Chutian has experienced many tragic battles, but the Battle of Yumen Pass is rare in his life.

The Mongol army's trebuchets used fire to raze almost the entire Yumen Pass to the ground.

In the era of cold weapons, it is not easy to fight a tough battle of such a scale.

"Good brother, you're here!"

Xu Fengnian saw that Chutian had arrived as promised, and before the two princes of Lao Qin and Mingguan had arrived, Chutian took the lead in coming to help, which was enough to see Chutian's attention to Yumen Pass and the Western Regions, as well as to Xu Fengnian and others.

Xu Fengnian couldn't help but give Chu Tian a thick hug and pat Chu Tian on the shoulder, not many people can understand the mood of the rest of his life after the catastrophe.

Chu Tian saved his life, so it was a friend of life and death.

Originally, Xu Fengnian and Chu Tian were just trading partners, but after experiencing a life-and-death battle, the foundation for cooperation was even more solid.

Tongque and Sun Jian also became friends during the Yellow Turban Rebellion and became brothers in life and death.

Ma Chao looked at Xue Rengui and Zhao Yun who were coming, Ma Chao, who was about to grow up, was almost the same as Xue Rengui and Zhao Yun in terms of force and appearance, and at this time, he couldn't help but be attracted to the two people who were somewhat similar to his style.

Of course, at this time, Ma Chao has not yet reached the peak, and there is still a gap between him and the two of them, in Ma Chao's eyes, Xue Rengui and Zhao Yun are the same predecessors as Wang Yanzhang.

"It's good to be alive."

Chu Tian also patted Xu Fengnian's shoulder to appease the magnates in Liangzhou.

Xu Fengnian integrated into the Xiliang family, as the main representative of the Xiliang family, and was the object that Chutian needed to woo.

At the same time, it was not easy for Xu Fengnian to dare to hold on to the Yumen Pass, defend this pass for the Han Empire, and hold back the two or three hundred thousand Mongolian troops.

According to the information obtained by Chu Tian and his own estimates, the Mongol army and its servant army entrenched in Dunhuang County numbered about 200,000 or 300,000, or even more.

Ma Teng took off his blood-stained helmet, and his scalp was injured because he was dodging the boulder thrown by the Xiangyang cannon, but Ma Teng, who was a descendant of General Fubo's horse aid, was stunned and asked Chu Tian cautiously: "Hugh'er, Tie'er, and Lu'er, are they okay?" ”

"They are all in Xia City at the moment, even if we are defeated, we will not worry about our lives."

Chu Tian didn't expect that Ma Teng was tall and big, and he still had iron tenderness.

Chu Tian muttered in his heart, Ma Teng's daughter punched her son, and she didn't care about it yet.

If you really have to think about it, the female debt will be repaid by her father......

Ma Teng also has ambitions, but as he gets older, his ambitions gradually fade. When he heard that his children were safe and sound in Xia City, he was secretly relieved.

"General Zhang He was burned by the fireball thrown by the Mongolian army's trebuchet, and he could not come to see the lord."

Ju Yi replaced Zhang He and came to see Chu Tian.

When Chu Tian heard that Zhang He was injured, he couldn't help but be shaken, Zhang He was one of the five good generals: "What is so special about the trebuchet used by the Mongolian army, that it can actually injure Zhang He?" ”

Among the high-level people present, Xu Fengnian, as a player, was well-informed, and at the same time, as a player, he knew the names of some large siege equipment: "It is very likely that the Xiangyang cannon used by the Mongolian army to capture Xiangyang City, that is, a large counterweight trebuchet, which can easily throw hundreds of catties of boulders." The city wall of Yumen Pass fell into disrepair and was bombarded by Xiangyang. ”

"Counterweight trebuchet?"

When Chu Tian heard this familiar term, he deeply felt that it was not easy for the defenders.

At present, the most advanced trebuchet in the Eastern Han Empire should be a large trebuchet (drawing production) in the Song Dynasty.

Chu Tian also obtained the Eight Bull Crossbow, a large siege weapon, but compared to the Xiangyang Cannon, it was a little worse.

Historically, Xiangyang City and Fancheng blocked the Mongol Empire's offensive for several years, and the Mongol army was a big headache for the strong city defense system of the Southern Song Dynasty.

Later, the Meng Yuan destroyed the Song Dynasty, and the Xiangyang artillery achieved results in a series of battles, and the fortresses of the Southern Song Dynasty were destroyed or surrendered.

It can be said that the existence of the Xiangyang cannon made up for the shortcomings of the Mongol army's lack of siege, so even if the Mongol army slaughtered the city, it rarely slaughtered craftsmen.

Temujin's cavalry, coupled with the Xiangyang cannon, the most advanced siege equipment in the current "Lord", made the Mongol Empire invincible in both field and fortified positions.

"Not only that, but the other party also has generals who can provide bonuses for siege equipment, similar to Liu Ye. The Xiangyang Cannon can also use special attack methods such as fireballs and wolf smoke. ”

Xu Fengnian felt that it was necessary to inform Chutian of all the information he had obtained.

The intelligence of these Mongolian troops was obtained by Xu Fengnian and a group of soldiers in exchange for their lives.

"You should be talking about those big guys, that's the Xiangyang cannon?"

Chu Tian saw the outline of the Xiangyang cannon, fifty Xiangyang cannons stood, each large trebuchet was several meters high, the tallest, even more than ten meters, throwing hundreds of pounds of stones, like a meteorite falling, even compared to the early bronze cannons, it was not inferior.

It is estimated that the inspiration for the bronze cannon is also a large siege equipment such as a trebuchet - the original bronze cannon fired a solid bullet, which is equivalent to the stone of a trebuchet, and the weight of the solid bullet is smaller than that of the stone used by the trebuchet. Correspondingly, primitive bronze cannons were more convenient to use than trebuchets, and the initial velocity of gunpowder propulsion was faster.

"No wonder Yumen Pass is almost in ruins...... The Yumen Pass is only temporarily reinforced, and in normal times, it is rarely used here, and the city walls have been weathered. ”

Chu Tian inspected the city wall of Yumen Pass, and the situation was not optimistic.

In the last years of the Eastern Han Dynasty, wars broke out, and all the princes were busy with civil wars and would not care about the fortifications such as Yumen Pass and the Great Wall of the Han Dynasty, after all, the nomadic tribes were weak during this time.

Gongsun Kang led 3,000 cavalry to defeat the 50,000 Buyeo army, and the Southern Xiongnu cavalry was chased and killed by the Mongol cavalry who were smaller than him......

Yumen Pass is also a Xiongguan that was rebuilt after Xu Fengnian retreated here, otherwise, the defense of Yumen Pass would be even more fragile.

"On the other side should be Temujin's army, he was driven away by me in Hetao and Monan, and finally wants to fight us in the Western Regions."

Chu Tian had already felt Temujin's hesitation.

In the face of the Han army led by him, Temujin was not sure of victory, so Temujin retreated again and again.

The Mongol Empire's defeats at Hetao and Monan resulted in the loss of about 100,000 cavalry and 200,000 or 300,000 tribal herdsmen, but they were not serious, and Temujin was still accumulating strength.

According to Chutian's inference, Temujin chose the location of the decisive battle with the Han Empire in the Western Regions at Luntai, Tianshan, or the Altai Mountains - in short, far from the Central Plains.

Temujin's strategy was similar to that of the Xiongnu Yizhi Shan Yu in the Battle of Mobei.

The closer to the Han Empire's Central Plains, Hebei, and Guanzhong hinterland, the easier it was for the Han Empire to supply its army.

Even if the Han Empire was defeated, it would soon be possible to recruit a large army from these densely populated places again to come to a decisive battle with the Mongol Empire.

In the long run, it was the Mongol Empire that would eventually fail.

Therefore, whether it was Temujin or the Xiongnu's Yizhi Xiandanyu, their purpose was to use the mobility of cavalry as much as possible to lengthen the supply lines of the Han Empire.

The longer the supply line, the fewer soldiers and horses the Han Empire could send and the greater the pressure.

Fighting at home, the Han Empire could send an army of one or two million.

If you fight across 10,000 miles, then it will be relatively reluctant to dispatch hundreds of thousands of people.

There is a very typical example, Emperor Yang Guang of the Sui Dynasty conquered Goguryeo, requisitioned a million troops, traveled a long distance, and encountered a cold winter, unable to pacify Goguryeo, but lost a large number of soldiers and horses, grain and grass, and weapons, and the people were overwhelmed.

Later, Li Shimin only sent more than 100,000 elite soldiers to capture more than 10 cities in Goguryeo, and plundered hundreds of thousands of people.

The princes of the Han Empire knew this truth, so Chu Tian would rather fight in relatively close places such as the Hetao Plain and the Monan Grassland, at the doorstep of Bingzhou and Youzhou, and the cattle and sheep provided by the Monan lords as food.

It's just that Temujin and the others also know this truth, and the place he chose to fight the decisive battle was either the Western Regions or Mobei, both of which were very far away from the Han Empire.

Yi Zhi Xian Shan chose the location of the decisive battle with the Han Empire was Mobei, and Chu Tian, Xu Fengnian and others who participated in the Battle of Mobei knew how difficult it was to march in Mobei, and Temujin ......

"Temujin intends to use the Protectorate of the Western Regions as a bait to lure us into an expedition, and then annihilate us in the Western Regions. Once the elite of our Han Empire is lost, then Hetao and Mo Nan will be its sphere of influence. ”

Summer Liang followed Chu Tian around, and also looked at the counterweight trebuchet standing west of Yumen Pass.

Xu Fengnian, Ma Teng, Han Sui and others were startled at first, but then nodded again.

Chu Tian and Xia Liang's inference coincided with their faint conjecture, otherwise it would not be possible to explain why Temujin tried to avoid decisive battles in Hetao and Monan.

After the Mongol Empire lost tens of thousands of soldiers and horses in Hetao and Monan, it immediately retreated, obviously preserving its strength.

"The Western Regions Protectorate is under Huo An's control, and Huo An is really unlucky. If it weren't for the Mongol Empire and the four khanates, maybe he would have been able to dominate Central Asia......"

Xu Fengnian finally found a person who was even more unlucky than himself - Huo An, the capital of the Western Regions.

Huo An had already conquered the kingdoms of Wusun and Dawan, prepared millions of grains and grasses, and was ready to defeat the Seljuk Empire and Khorezm and become the overlord of Central Asia, but the Fourth National War disrupted his deployment, and the Western Regions Protectorate was in danger.

If the Western Regions Protectorate is a bait, then Huo An happens to be the Western Regions Protector, and he can't be unlucky.

"In the position of someone else in Hoan, it is difficult to destroy the Ögedai Khanate in this situation, and it seems that his main force has not been completely damaged...... Whoever is in this position, we must be saved. ”

When Chu Tian discussed with Xu Fengnian and others to open up the Hexi Corridor and go to the Western Regions, Zhu Jun, whose battle armor was stained red with blood, arrived, with a sad expression: "Huangfu Song, the general of the expedition to the north, I'm afraid it won't work......
