At this time, the Yinling garrison was leading his corporal to patrol the city, which was also discussed in advance with Hua'an and other generals of the Northern Expeditionary Army, and the soldiers of the Northern Expeditionary Army were responsible for guarding the city, and the original defenders of Yinling were responsible for the security of the city.

Because Hua'an felt that even in the face of the crazy siege of a strong enemy, he could not relax the security in the city, especially to beware of the spies who infiltrated the city to sabotage, besides, the combat power of the Yinling defenders was not strong, and even if the city was defended, it would not play a big role.

But Hua'an obviously did not expect that the enemy's siege weapons were so complete, at this time, under the frantic attack of the enemy's siege equipment, the city gate was already in danger, and it was imperative to defend the city at this time, after all, once the city was breached, the consequences would be unimaginable.

When the Yinling garrison received Hua'an's request, he was stunned for a moment, but when he heard that the city gate was about to be captured, he immediately agreed to lead all his soldiers to reinforce the city gate.

The defenders of Yinling who arrived at the city gate replaced the soldiers of the Northern Expeditionary Army, who were already exhausted, and all the soldiers under the command of the Yinling garrison found more wooden pillars to reach the city gate tightly.

The enemy's ramming vehicles were still hitting the city gate, but they were definitely unable to break through the city gate for a while, and the hearts of the city defenders suddenly settled down a lot.

Hua'an, who was standing on the city wall, brandished a big knife and slashed down the enemy troops who tried to step on the city wall one by one, and the surrounding defenders also fought with all their might, no one was timid, and no one retreated.

Under the full resistance of the Jin army defending the city, the enemy army besieging the city became weaker and weaker, and the shouting of killing was much quieter.

Taking advantage of the gap when he had just finished slashing and killing an enemy soldier, Hua An leaned out of the female wall and looked down, and the enemy troops under the city were still densely packed, especially the sword and shield soldiers holding shields were the most.

At least a dozen enemy soldiers on each side of the siege chariot were slamming into the city gate, and beside these charioters were more than twice as many giant shieldmen who specialized in protecting them, and these giant shield soldiers were raised in pairs to protect the charioters with huge shields large enough to cover three or four people.

"The shield is big enough." A sneer appeared at the corner of Hua An's mouth, and a sharp arrow swept past his cheek, startling him into a cold sweat.

"We must do our best to solve the rushing car under the city, and if we keep hitting it like this, the already dilapidated city gate of Yinling City will be knocked apart."

Hua An made up his mind, turned around and picked up a thick piece of rolling wood, and smashed it into the rushing car under the city, and the rolling log smashed on a huge shield, and suddenly this huge shield was shattered, and the three enemy soldiers under the shield naturally died.

But soon there were soldiers to replace him, and Hua'an smashed several huge shields one after another, all of which were quickly replaced by the enemy.

The enemy's giant shield is wooden, and the siege car is also wooden, which can only be effective by attacking with fire, Hua'an did not expect to attack with fire, but the gate of Yinling City is also made of heavy wood, in case of fire attack, the fire will burn, in addition to burning the enemy's siege car and giant shield, it can also burn the gate of Yinling City to ashes.

Once the gate of Yinling City was burned to ashes by the fire, the city gate would be broken, but if it was not attacked by fire, there would be no other way to deal with the rushing car for a while.

At this time, the only way is to control the fire, so that it can only burn the enemy's rushing cars, not the gates of Yinling City, but how can the fire be ruthless and obey people's wishes, Hua'an can't help but feel funny when he thinks of this.

"Click, click......" The city gate made another sound of wood breaking.

This time, because the sound of the battlefield fighting was quieter, Hua'an and many soldiers defending the city heard it.

"Big brother, the city gate is about to be knocked open, what should I do." Wang San looked at Hua An and asked anxiously.

"What else can I do, block the city gates, and fight with them." Thunderstorm's face was murderous, and at this time, his whole body was stained red with blood, and he looked very enjoyable to kill.

"The enemy has the advantage of strength, but I'm afraid I can't stop it!" Huaan shook his head.

At this time, the four sworn brothers all gathered around Hua'an, discussing together how to solve the enemy's siege and rush to the car.

Seeing Hua An shaking his head again and again, Tie Niu's eyes lit up, and he yelled: "Big brother, it's better to put a big fire and burn his mother to death." ”

"Yes, Brother Tie Niu is right, set it on fire." Thunderstorm, Zhao Wu, and Wang San spoke in unison.

"Hey, hey, hey." Iron Bull laughed happily as he was praised.

Hua An smiled at the corner of his mouth, shook his head lightly, and said: "The fire attack can naturally burn the enemy's rushing cars, but it will definitely burn the city gate to ashes as well." ”

"That's right! Didn't the old cow's fire burn even the city gate, oops! Fortunately, there was a reminder from the eldest brother, otherwise this Yin Ling City would not be able to hold it. Iron Bull touched his head and regretted it again and again.

"If you can't burn it with fire, can you use water?" Zhao Wu, who had been silent, opened his mouth to say.

"You kid still want to drown the enemy with water, dreaming? If you can't come up with a good idea, you can't do it. Hearing this, Tie Niu looked at Zhao Wu for a while.

Thunderstorm and Wang San also shook their heads again and again, after all, the city is a flat land, and the front is huge, how much water does it take to flood it.

Zhao Wu glared at Tie Niu, looked back at Hua An, and explained: "Big brother, I mean to pour hot water from boiling soup on the enemy's body, even if the killing effect on the enemy is not good, but the water will make the ground slippery, and the enemy's soldiers besieging the city will not be able to use too much strength. ”

"Oh." When Thunderstorm and the others heard this, they immediately felt that there was some reason, and if the enemy army slipped under their feet, the power of the siege and charging vehicles would be weakened a lot.

Hua An shook his head slightly, this strategy can indeed weaken the power of the enemy's chariot, but it can't completely destroy the enemy's chariot, it only delays the enemy's time to break the city.

Fire attack doesn't work, and water attack doesn't work either, so what about water and fire sharing? Water can extinguish fire, and it can extinguish a burning flame.

Hua An had a flash of inspiration in his mind, and suddenly thought of a clever plan that could control the fire.

"Tie Niu, you take a group of people to prepare for a fire attack, Zhao Wu, you take a group of people, go to the city to get water, at the head of the city, behind the city gate, you must prepare, go quickly." Huaan ordered loudly.

Tie Niu and Zhao Wu were stunned for a moment, and then agreed: "Yes, big brother." ”

Although they couldn't figure out what Hua'an's intentions were, they knew that their eldest brother must have his reasons for doing this.

At this time, taking advantage of the opportunity of the Northern Expeditionary Army Hua'an and others to discuss things, dozens of elite enemy soldiers climbed onto the top of the city, and more than a dozen people gathered in a group to attack the Jin soldiers defending the city back to back.

Since the elite soldiers of the enemy army climbed the city wall, they had no way to retreat, and they fought like outlaws, and even blocked the counterattack of the defenders several times the number of troops.

"Thunderstorm, Wang San, throw the enemy army who climbed the city wall down the city." Huaan ordered loudly.

"Big brother, don't worry." After Thunderstorm and Wang San finished speaking, he turned around and walked towards the enemy, how could only a dozen elite soldiers be the opponents of Thunderstorm and Wang San, in the blink of an eye, more than ten people were picked down by Thunderstorm and Wang San, one by one.

It didn't take long for the fire attack materials prepared by Tie Niu to be placed in front of Hua'an.

"Big brother, you should tell us about the use of fire and water!" Tie Niu was curious and couldn't help but ask.

"You'll find out later." Hua An smiled indifferently and sold Guanzi.

"Big brother, the water is coming." Zhao Wu led a group of soldiers and walked up to the city with dozens of jars of water.

Hua An nodded and asked, "Is the water behind the city gate ready?"

When Zhao Wu heard this, he said loudly, "Big brother, don't worry, it's all behind the city gate, and those Yinling defenders are holding water tanks against the city gate?" ”

"Okay, that's it." A smile appeared at the corner of Hua An's mouth, and he ordered: "Iron Bull, set fire." ”

Tie Niu was stunned when he heard this, waved his hand and said, "Big brother, if this city gate is burned, it won't be bad for me." ”

"Don't worry, isn't there still water here?" Hua An reprimanded angrily.

Tie Niu's eyes rolled, as if he understood something, and said loudly: "Soldiers, set fire." ”

Suddenly, dozens of soldiers lit the forage poured with fire oil, and threw them at the siege car under the city, and a ball of fireball fell on the enemy car and the giant shield under the city, and the scorching flames soon ignited the giant shield and the car rush.

The enemy soldiers under the shields could not stand the scorching heat, and they abandoned their huge shields and ducked backwards, while the soldiers who ran slowly or were directly hit by the flames were quickly consumed by the flames, and they were killed.

Zhang Ju, the main general of the enemy army who was standing in the distance, saw that the vanguard could not conquer Yinling City for a long time, he was furious in his heart, and was about to increase his troops, when he suddenly saw the fire burning at the gate of the city, and he couldn't help but sneer in his heart.

"The Jin army is really stupid, thinking that it will be fine if it burns our army's rushing car with a fire, but don't you know that the city gate can also be burned down by fire." Zhang Ju said and looked at the few generals beside him.

"General, it is better to withdraw the front army, and when the city gate is reduced to ashes, our army will attack again." A ministry will build a yì road.

"That's right, when the city gate is reduced to ashes, our army will attack the city directly through the city gate." The corners of his mouth twitched, and he said fiercely: "After entering the city, I will be going to wash the Yin Ling City in blood." ”

"Summons the former army, withdraw the troops."

"Bell, bell, bell, ......bell," a crisp gong sounded from among the enemy troops.

"Big brother, the enemy army is ginging, is it going to retreat." Wang San looked at Hua An with a puzzled expression.

As soon as Wang San's words fell, the enemy army besieging the city slowly retreated like a tide, leaving dozens of ladders quietly leaning against the city wall.

There were thousands of corpses left by the enemy soldiers under the city, and all kinds of broken shields and huge shields that covered arrows were scattered scattered under the city.

"It's strange that the enemy army has the advantage of strength at this time, and instead of increasing the troops, it retreats, what is the reason." Hua An frowned, and couldn't think of a reason for a while.

At this time, the flames of the enemy troops charging the car under the city became more and more vigorous, and there was a crackling sound from time to time, and Tie Niu exclaimed: "Big brother, the fire is burning more and more, and it is about to burn to the city gate." ”

Hua An looked down and saw that the car was completely surrounded by flames, and the flames were moving towards the city gate, which would not be long before it would be ignited.

Looking at the city gate that was about to be set on fire, Hua An seemed to understand a little, daring to love the enemy army will wait for the city gate to be burned to ashes before attacking, in that case, it will be much easier to attack the city.
