"Fortunately, you helped me in time, otherwise we might have been wiped out."

Huangfu Song, Zhu Jun, Xu Huang and others almost lost their strength, and joined Feng Yi, Zhang He, Ju Yi, Xie Ai and other generals who came to support.

Among these people, Xie Ai, who is in white clothes and white hats, is a strange person, even Huangfu Song doesn't know his origin, only knows that he is a native of Dunhuang, Liangzhou, and has a certain ability to command soldiers and horses.

At this time, the Yumen Pass was in difficulty, and Xie Ai immediately counted the soldiers and horses and came to support.

The 30,000 Xiliang Army is a combat force that cannot be underestimated.

Temujin did not know which generals and soldiers and horses the Han Empire had sent to support Yumen Pass, and he would not dare to act rashly for a while.

"On the orders of the general, we came to help defend the Yumen Pass, and we happened to meet this person. This person was widely scouted in Jiuquan County, originally to deal with Xu Fengnian and monitor one of the moves in Jiuquan County. Just in handy. ”

Feng Yi met Xie Ai on the way, and Xie Ai's scouts in Jiuquan County learned that a Mongol army was heading south, so he joined Feng Yi and came to the rescue together.

Huangfu Song looked at Xie Ai, this person did have some skills, otherwise Lao Qin would not have handed over the important Wuwei County to him to take care of.

"With so many soldiers and horses in the Hexi Corridor being transferred here, can Jiuquan County and Wuwei County have enough troops to defend them?"

Huangfu Song thought that Wuwei County sent 30,000 people to come to the rescue, which was a good thing, but it also meant that Wuwei County was empty.

"The Great General sent not just one legion, but two legions."

Not only Feng Yi's Thorn Slaying Legion, but also Cao Ren's Iron Wall Legion, directly consumed gold and silver, and used the teleportation array to reach Xiliang from Jizhou.

For this reason, Chutian paid millions of taels of silver, just to keep the Hexi Corridor.

The Hexi Corridor cannot be easily lost, and the Yumen Pass cannot be easily lost.

Only then did Huangfu Song and Zhu Jun rest assured, and together with the two legions, more than 100,000 troops, guarded against Temujin, and continued to march towards Yumen Pass.

Once the defenders of Yumen Pass are replenished with more than 100,000 reinforcements, it will be extremely difficult for the Mongol army to capture Yumen Pass.

At Yumen Pass, the defenders led by Xu Fengnian blocked the onslaught of the Mongol army, and the trebuchet destroyed almost all the arrow towers.

Even the wall of the Jade Gate Pass is already scarred.

The Xiliang army held on to it.

Xu Fengnian personally shot an enemy soldier trying to climb the city wall with a bow, and his armor was covered with sword marks.

When reinforcements from the Han Empire appeared behind Yumen Pass, the Xiliang army cheered.

Temujin made a detour through the desert in the north and breached the Great Wall, and the defenders of Yumen Pass almost became alone, but now it seems that Temujin's plan failed, and the reinforcements of the Han Empire successfully arrived at Yumen Pass, increasing the strength of Yumen Pass by three or four times.

"I didn't expect Chu Zimou to really get along with the promise and send the legion to support, otherwise he would almost not be able to return to the pass."

Xu Fengnian was happy for a while.

The situation is not optimistic, and the Mongol trebuchets and servant armies will consume all the defenders until they surrender.

"I didn't expect that one day, I could guard the Yumen Pass. Even if there are 100,000 enemy troops outside the Yumen Pass, they will not want to cross the Yumen Pass by half a step. ”

Huangfu Song, who also belonged to the generals of Xiliang, looked down on the Mongolian army under the city.

He had already learned the most powerful cavalry of the Mongol Empire, and when he looked at the ordinary Mongol cavalry, he was not very afraid.

The Mongol commander who commanded the siege was Ali Hague, a hero from the Cowardly Xue Army, who could provide bonuses to siege equipment and siege troops.

Ali Hague obviously can't bring Huang Fu Song's sense of oppression.

The characteristics possessed by emperors are often more domineering, and it is difficult for ordinary generals to compete with them, and Ali Hague is much weaker than Temujin's momentum.

"Temujin is in the Hexi Corridor, why not break the Mongol army outside the city, recover Dunhuang County, and open up the passage to the Western Regions?"

After Zhang He arrived, he immediately proposed to attack.

Xu Fengnian nodded: "That's what I mean." ”

The most troublesome commanders of Temujin, Subutai, Jebe, and Muhuali were not on the battlefield of Yumen Pass, as long as the Han generals were strong enough, they might be able to defeat the Mongol army under Yumen Pass.

Xu Fengnian got the soldiers and horses of several veteran generals and young generals, and he was confident to go out to meet Ali Hague!

"Wang Tiegun, count the Long Xiang Army!"

Xu Fengnian immediately prepared a large army for the counteroffensive.

Suddenly, Liang Xing, the general of Han Sui's department standing on the watchtower, reported an important news - the reinforcements of Ali's Hague Legion had also arrived!

Thousands of men in this support army were blonde and blue-eyed, unlike the other Mongol cavalry.

Not only that, the outfits of these thousands of people made Xu Fengnian feel very familiar.

"Roman legions? This is supposed to be Temujin's legion using captured Roman soldiers......"

Xu Fengnian and the other princes of the Han Empire knew that the Roman magnate Crassus was captured by Temujin during the Third National War, and was considered the most unlucky Roman magnate.

Temujin was also a knowledgeable man, using the Roman eagle banner to rebuild the Roman legions for Crassus.

This Roman legion was a legion of true Roman citizens, with a high combat power, which was not comparable to the servant army.

The eagle flag was unfurled, and sure enough, there was a Roman legion. This Roman legion was dominated by Roman heavy infantry, with Mongol cavalry, and cavalry was no longer the weakness of Roman legions.

"Stop the plan to attack the Mongol army out of the pass!"

Xu Fengnian had never fought against the Roman legions, and he was uncertain about the true combat power of the Roman legions, so he did not dare to act rashly.

After all, the Roman legions were a well-known branch of the army.

Outside the Jade Gate, the hapless Crassus was ordered to lead the arrival of the Roman legions, numbering 5,000, but all of them were high-level troops.

For the order of the Mongol Great Khan, he had to obey.

The Roman legions were accompanied by a troop of Arab artisans.

Arab craftsmen brought valuable drawings, and they also had the skills to make some special instruments.

"An unprecedented siege machine will be put into use to capture this ancient pass."

Ali Hague had high hopes not for the Roman legions of Crassus.

Although the Roman legions were indeed very good at hand-to-hand combat, the Roman legions could not be replenished by the Mongol Empire, which meant that they were also consumables and cannon fodder.

It's just that the cost of this consumable is relatively high.

What Ali Hague really valued was the Arab craftsmen who came to assist in the attack on Yumen Pass.

The top craftsmen of the Arab Empire, with the skill, as long as there are extremely precious blueprints, then a new type of trebuchet will be made - the Xiangyang Cannon.

This counterweight trebuchet uses a winch to lift a heavy object, and converts the kinetic energy generated by the falling weight into kinetic energy, throwing the stone at the other end of the lever, which is very powerful.

In "Lords", only those who have construction blueprints can produce the corresponding siege equipment.

The Xiangyang cannon is already a trebuchet at the pinnacle of the cold weapon era!

This time, Temujin took out the hole card of the Xiangyang Cannon, in order to capture the Yumen Pass as soon as possible and defeat the princes of the Han Empire.

Arab imperial warmakers worked around the clock to build siege engines.

Temujin, who had invaded the Hexi Corridor, sacked the towns along the way, unable to annihilate the armies of Huangfu Song and Zhu Jun, so he planned to take advantage of the situation to capture the governorship of Jiuquan County.

However, Cao Ren and the favored Tiebi Army arrived and held on to Jiuquan County, and Temujin had no choice but to divide his troops and capture several towns.

"Mu Huali of Hetao is asking for help, he is being attacked by the cavalry of the Han Empire, please give an order to the Great Khan!"

When Temujin was preparing to open up a battlefield behind the Hexi Corridor, the commanders Mu Huali and Bor Hu in Monan fell into an unprecedented crisis, and the commanders of the Han Empire, Yue Fei and Li Mu, attacked the Hetao area in a big way, intending to encircle and annihilate the two legions.

When Temujin learned that the Han Empire had sent two wary commanders, he fell into a brief silence.

Whether it is Yue Fei or Li Mu, they are all one of the top cavalry commanders, and Mu Huali is difficult to support alone.

As for Bolhu, one of the four cowardly Xue, he is still a step behind Mu Huali, Yue Fei, Li Mu and others.

"It seems that it is necessary to make a trip to Monan. Or should the venue of the decisive battle be chosen in Mobei? ”

Temujin's army soon left Jiuquan County with the plundered gold and silver, and disappeared outside the pass.

Calm has returned to the Hexi Corridor for the time being.

The battle of Yumen Pass was still going on, and the Mongol army besieging the city built a number of siege towers, ladder trucks, and trebuchets.

This time, the trebuchet that bombarded Yumen Pass was even more terrifying, and a boulder weighing two or three hundred catties fell from the sky, smashing a military general defending the city into meat sauce!

The city gate tower was hit by a boulder, and with a bang, it collapsed a corner, which was shocking!

The new trebuchet used by the Mongol legion, which is more powerful and has a longer range, coupled with the bonuses of some Mongolian generals to siege equipment, causes dense and extremely destructive meteorites to bombard the city walls!

Rumble!

There was a crack in the wall of Yumen Pass, and the city bricks wrapped in rammed earth shattered and fell off, and even the defender soldiers on the city wall felt the shaking under their feet!

Ordinary trebuchets are not so scary.

The Xiliang Legion, which was stubbornly defending the Yumen Pass, soon realized that the Mongol army had replaced it with a new trebuchet!

This kind of trebuchet, the Han Empire did not have a corresponding drawing, and it could not be manufactured.

Xu Fengnian seemed to think of a corresponding large-scale siege weapon, and his face turned slightly pale.

In the era of cold weapons, the army of the Mongol Empire besieged the fortified city of Xiangyang and could not take it for a long time. Later, the Mongol army was assisted by craftsmen from the Western Regions to build large counterweight trebuchets, that is, Xiangyang cannons, to bombard Fancheng, successfully capture Fancheng, and force the defenders of Xiangyang City to surrender.

The Xiangyang cannon is already the pinnacle of the cold weapon era, and it still belongs to the scope of stone artillery.

If you want to surpass the Xiangyang cannon, then you have to make a real cannon - the original bronze cannon.

Under the Yumen Pass, the siege equipment used by the Mongolian army to bombard the Yumen Pass is likely to be the legendary Xiangyang cannon!

"If it is really Xiangyang Cannon, then the pressure we have to bear will be even greater......"

Xu Fengnian knew what the appearance of the Xiangyang cannon meant.

The defenders had to endure the bombardment of the Xiangyang cannon and the huge psychological pressure brought by it, and stubbornly defended the Yumen Pass.

Not only that, but the Xiangyang cannon destroyed all the city gate towers, arrow towers, and battlements, and stoned the soldiers to death, which was not the worst situation.

The worst situation is that in case the city wall is collapsed by Xiangyang shelling, the Mongolian army rushes up, and there is no defender of the city wall, whether it can hold the Yumen Pass, there are two to say.

"Build thirty large Xiangyang cannons and raze Yumen Pass to the ground."

Seeing the great power of the Xiangyang cannon, Ali Hague, the general of the Mongol army, almost demolished the towering gate tower on the city wall, he was very satisfied with the performance of the Xiangyang cannon, so he ordered the craftsmen of the Arab Empire to produce the Xiangyang cannon for himself.

A number of Xiangyang cannons gradually took shape under the city, constantly adding into the ranks of siege equipment, and the situation of the defenders of Yumen Pass became more and more critical.

The boulder thrown by the Xiangyang cannon, even if the military general hits, will be seriously injured if he does not die.

When one of Han Sui's generals led the cavalry to inspect the city defense, he was hit by a boulder weighing 200 catties and died instantly.

The Xiangyang cannon brought a huge psychological shadow to the defenders.

Even if the Mongol archers tried to pile up mountains of earth and shoot arrows at the defenders from a high position, the defenders could still hold off the Mongol archers' arrows with their shields.

But in the face of the boulder projected by the Xiangyang cannon, even if you hold a shield to block, it will not help. The power of the boulder is much greater than that of a normal bow and crossbow.

"The Xiangyang cannon has shaken the morale of the army, and we must find a way to burn it. The number of Xiangyang cannons under the city exceeds twenty, and if the number of them is allowed to increase, it will be difficult for Yumen Pass to hold ......"

Xu Fengnian summoned a group of military generals, Feng Yi, Zhang He, Ju Yi, Xie Ai, Huangfu Song, Zhu Jun and other military generals, all of whom were under the jurisdiction of Xu Fengnian at this time.

Temujin left a back hand, not only dispatched Crassus's Roman legions to help, but also brought the Arab warmakers who could make Xiangyang cannons to attack Yumen Pass, Xu Fengnian had to take the initiative to attack in order to burn the Xiangyang cannons.

The existence of the Xiangyang cannon seriously threatened the safety of Yumen Pass.

If the Xiangyang artillery bombardment is allowed to occur, the Yumen Pass will be in danger.

"The trebuchet that went out of the city to attack the Mongol army was extremely dangerous. But the general died in a hundred battles, and since he chose to defend the Yumen Pass, he had to prepare for the horse leather shroud. “

Xu Fengnian summoned the generals and mobilized.

The enemy army has strengthened the offensive on Yumen Pass again and again, and even the hole cards such as Xiangyang Cannon have been revealed, which shows that the Mongol Empire is bound to win Yumen Pass.

The more the other party wants to get something, the more they can't give it, so that they can disgust the other party.

Wang Yanzhang took the initiative to serve as a pioneer, and Ma Chao was willing to follow.

After Ma Teng became Hanchen, he volunteered for his son Ma Chao, although he was worried about his safety, but he couldn't shirk it.

Zhang He and Ju Yi each carried weapons and participated in the attack.

Xie Ai did not take an active part in the burning of the trebuchet: "I am not good at arching horses, so I can only command and answer you from the city wall." ”
