When the news reached the army, Liang Tingfen was stunned, the Hexi Army actually had such a big killing weapon?

This is not to blame Liang Tingfen, the fact that the Hexi Army has iron and thunder is listed as a top secret by Zhu Jun, he is afraid of shaking the morale of the army, so he wrapped this matter tightly, only the intelligence agency and a very small number of high-level henchmen know about it, and even the deputy military division like Wang Yu does not know.

Liang Tingfen looked at the tall and sturdy Guancheng, but he didn't have any siege weapons, he felt a burst of regret in his heart, and immediately asked people to find Wang Yu, and scolded: "You old bastard, idiot, idiot, I'm blinded by lard, I actually listen to you, we can't take back Dunguan, what should we do?" If Luoguan is lost, how can you replace the main bus? You're a stupider old bastard than a pig! ”

Wang Yu was scolded so much that his head spurted blood, he held back his anger and explained: "General rest assured, the enemy army does not carry grain and grass baggage, they will not last long, at the latest in five days, they will definitely retreat north, and everyone will go to the original point again." ”

"Okay, I'll wait for you for another five days, and if you can't recapture the pass after five days, I'll cut off your dog's head to sacrifice the flag!"

Liang Tingfen waved his hand, "Camp on the spot!" ”

He ignored Wang Yu and turned his horse's head away.

Wang Yu looked back at the high Guancheng, he was really a little worried in his heart, his strategy was obviously seen through by the enemy, but why did they still lead the army into the Luoluo Road, could it be that he was still negligent?

The day gradually dawned, Zhu Zhu's camp appeared outside the city of Dunguan, the army carried not many camp tents, only a few hundred, and dozens of people were needed to squeeze a big tent, but there was no way, they had to intercept the logistics supply of the Hexi army here, and wait for the Hexi army to run out of food and retreat.

At the same time that Zhu Zhu's army returned to Dunguan, Yao Jin led an army of 15,000 to Luoguan.

The natural conditions of Luoguan were even more unfavorable to the besieging party, and the army had to walk slowly down the deep stream, walk by the river, and pass through a canyon, in which a fortress appeared, and on both sides of it were steep mountains.

There is a crescent-shaped arch below the gate, about a zhang wide, the arch is only a foot high above the water, the river flows under the arch, but people can't get through, under the water is an arm-thick iron fence, stretching to the bottom, against the riverbed.

The reason why Luoguan is more difficult to attack is that the canyon is very narrow, it can only accommodate more than 100 people to attack the city at a time, and hundreds of soldiers can hold the city.

At the end of the night, the moon was dark and the wind was high, thick dark clouds covered the moon, and the valley was dark, which was a good opportunity to attack the city, and the defenders were also aware of this, and the main general Zhang Bingquan ordered to strengthen the defense at night, and the city was full of torches, which shone as if it were day within a zhang from the city wall, even if the enemy army arrived under the city, it would be immediately discovered.

The defenders at the head of the city increased to three hundred, a hundred more than during the day, and none of them were allowed to sleep, vigilantly watching every move outside the city.

At this time, a soldier suddenly noticed a foreign object floating on the surface of the river, and it was dark and could not be seen clearly, and the soldier immediately turned around and shouted: "General, there is movement on the river!" ”

Zhang Bingquan was inspecting the city, he heard the shout, and immediately walked forward quickly, "What's the matter?" ”

"General, look at that!" The soldier pointed to the river.

Zhang Bingquan looked closely, and sure enough, he saw an object in the shape of a raft floating from the river to this side, about a dozen zhang away from the city wall.

"Shoot me the arrows!"

Dense arrows were fired at the rafts, most of which were nailed to the rafts, and faintly passed on to the 'dang! While! The sound is like an echo on metal.

Everyone looked at each other, could it be that there was an iron pot on it?

They did guess correctly, the raft was indeed a huge iron can, a large iron fire thunder, the iron fire thunder was placed in an open wooden box, and the wooden box was placed on a raft, and the two water ghosts hid under the raft and drifted down the river.

As the walls got closer and closer, the arrows from above became more violent, and at this time, a soldier shouted: "General, there is no one on the raft!" ”

"Pour oil on fire!" A muffled voice came from above.

The wooden box has a fire fold, and the two water ghosts who originally wanted to show their heads heard this, and the two of them were shocked, and they dropped the wooden box and desperately dived back, swimming as far as they could.

'Wow! A bucket of oil was poured on the city, and then a dozen rockets were fired on the raft, and the flames burst into flames, as well as the entire tin can.

All the soldiers stared at the raft below, and before they could cheer, a red light burst out, followed by an earth-shattering explosion, and the water splashed into the air, and countless soldiers fell screaming.

Thick smoke filled the city, and the city wall above the river was blown open a large gap two feet high, and a huge crack went straight to the top of the wall, only a terrible cracking sound was heard, and the city wall lost its support and collapsed with a bang.

Two hundred paces away, the five thousand soldiers of the Hexi Army lying on the ground saw the city wall collapse, they cheered, turned over their horses and galloped towards the city wall, thousands of cavalry rushed to the city wall like sharp swords, the soldiers in the city still did not recover from the huge panic of the explosion, the five thousand cavalry had already rushed through the gap, and the cavalry fired arrows in unison, shooting at the enemy soldiers in panic.

The 3,000 soldiers woke up like a dream, turned around and ran wildly into the canyon, but the 5,000 cavalry followed them unhurriedly and slowly, constantly firing arrows in the back, driving thousands of enemy troops to rush to the large formation at the mouth of the canyon.

Ten thousand troops were stationed at the mouth of the canyon, and they were alarmed by the sound of explosions, and they all rose up to meet them.

The soldiers who fled back shouted that they were all their own brothers, and the soldiers in the army hesitated not to shoot arrows, but suddenly countless cavalry were killed from the defeated army, and in an instant they rushed into the enemy's array.

5,000 Hexi cavalry used the fleeing enemy army as a cover, instantly rushed into the enemy's large array, and caught the enemy off guard, at this time, Yao Jin led 10,000 cavalry to kill, and the two armies were mixed together in the wilderness outside the mouth of the canyon.......

The combat effectiveness of the infantry was far inferior to that of the cavalry, and the main general had been killed, the enemy army had lost its command, and the disadvantage in the melee was obvious, and after only half an hour of fighting, Zhu Zhu's army finally could not resist, and the whole army was defeated.

The soldiers threw away their armor and scrambled to run for their lives in the wilderness.

The Hexi army only chased out a few miles before stopping the pursuit, began to gather prisoners of war, clean up the battlefield, Guo Song had a clear order, the capture of Luoguan is the end of the battle in Guannei, although it can be killed into Fangzhou, into Tongzhou, but Guo Song does not have that plan for the time being, as long as they control Luoguan, they can enter the pass at any time, exerting great pressure on Zhu Zhu.

As the day dawned, nearly 6,000 prisoners of war began to transform into laborers, clearing the battlefield, clearing the bombed-out passes, and preparing to build a new one.

The Hexi army seized a large amount of grain and baggage, as well as tens of thousands of mules and donkeys in the enemy's camp, and Yao Jin immediately ordered the soldiers to drive the mules and donkeys loaded with grain to Dunguan.

The confrontation at Dunguan had entered its third day, and in the morning, Guo Song received an urgent report from Yao Jin that Yao Jin had captured Luoguan and opened the door to Guanzhong.

Guo Song has been waiting for this news for three days, and the time to end has come.

Guo Song immediately ordered: "Pass my order, release gunpowder arrows!" ”

Hundreds of soldiers fired arrows into the sky at the same time, and the rockets exploded in the air in a series of explosions, which could be clearly heard ten miles away, and the scouts of the Hexi army ten miles away heard the sound of gunpowder arrows exploding, and immediately urged their horses to run into the distance.

At this time, the 30,000 cavalry led by Liang Wu was already waiting for orders fifty miles away, and once the scout notice arrived, the army would kill the enemy.

A series of explosions also attracted Liang Tingfen, he walked out of the big tent, staring at the juncture puzzled, he couldn't figure out what was going on?

At this time, Wang Yu rushed over with a solemn face and said: "General, this is a signal that the enemy army is likely to break through, and we must prepare for battle immediately!" ”

Liang Tingfen suddenly came to his senses and immediately shouted: "Pass my order, the army will assemble and line up!" ”

Bands of soldiers rushed out of the camp and quickly assembled in the wilderness, and soon formed a large formation of 20,000 men.

Guo Song saw clearly in the city, and sneered: "It seems that they are not stupid enough to come home, and they still know that danger is coming." ”

Time passed, and the soldiers in the wilderness beneath the city waited for two hours, when they were exhausted. Suddenly, a low trumpet sounded in the north.

"Whew-"

Liang Wu's 30,000 cavalry finally arrived at Dunguan.
