At the back of the city wall, the soldiers on the steps of Cao were waiting quietly, crowded but neat, waiting to climb the city wall, and once their companions died, they would climb the city wall to continue the battle.

"Not good! Bad! Bad! Xun Yu said three things in a row, and then walked to Xiahou Yuan's side with difficulty under the escort of the guards and said, "General Xiahou, do you see the enemy's forward rush?" ”

"See, what's wrong!" Xiahou Yuan's eyes stared at the soldiers under the city wall, and he said without looking back.

"Resist Lao Tzu! No one can return! Xiahou Yuan replied to Xun You's words and shouted.

"General! It stands to reason that there shouldn't be so many storming cars attacking the city, two or three of them are enough, why are there as many as ten, there must be something strange among them, those rushing cars in front have not been destroyed, why are the rushing cars behind pushed over, this shouldn't be! And those rushing carts are not like rushing carts at all, the wood used should be very light, and it can't cause much damage to the city gate at all, and those soldiers are pushing the rushing carts too fast," Xun You explained loudly.

As soon as Xun You said this, Xiahou Yuan also noticed, and he cut off the soldiers who were about to climb up from the city tower with a sword, and then said without looking back: "What do you think the military advisor should do?" ”

"I think the enemy is attacking the walls with such a large formation! Although this Hongnong city is not as strong as one-tenth of Chang'an, it is not easy to be breached, and its mystery must be in the rush. Xun Yu said.

"Is that to stop the rushing cars from approaching the city gates?" Xiahou Yuan said loudly.

"Exactly!" Xun Yu Dao.

"Suppress the cart with arrows to stop its advance, use all the oil on the cart to destroy it, and pour it down as it approaches the city gate! How about burning it all? Xiahou Yuan asked.

Xun You said loudly: "No! ”

"Why?" Xiahou Yuan asked.

"Zhong Xuan is a smart person, he can also see this situation, I think he is also likely to do this, but Chang'an is lost. There must be a mystery in this rushing car, and it must not be allowed to approach the city gate! ”

Xun You insisted.

Xiahou Yuan was stunned for a moment, looked back at Xun You and said, "Then what should I do?" Isn't it possible to open the gates of the city and kill them? ”

"Yes!" Xun You said.

"Joke, how can there be a defender of the city to open the city to meet the enemy! Besides, there is a huge disparity in the strength of the enemy and us! Xiahou Yuan said.

"General Xiahou! The last general felt that what the military advisor said was not unreasonable, I think the rushing car was strange, you see that the rushing car led by the leader has the cover of the shield soldiers, but he is not in a hurry to rush forward, it is waiting for the rushing car behind to catch up! At most one chariot came up at this gate, why did it use ten chariots? Zhang He was killing the enemy while approaching Xiahou Yuandao.

"Hop Shield!"

Wei Yan gave an order, and eight hundred shield soldiers joined together to surround the ten rushing cars, protecting the rushing cars and slowly rushing towards the city gate!

One two three four!

One two three four!

The shield soldiers shouted slogans! Moving forward in a very orderly manner!

"This is a professional soldier!"

Zhang He sighed, he looked at the iron armor wall that was lined up, as if it was a moving iron castle, advancing towards the city gate.

Xiahou Yuan did not take Xun You's method of opening the city gate to fight, but he asked Cao Hong to lead five hundred soldiers to guard in front of the city gate in advance, and then let the left and right use stones to keep smashing towards the iron armor shield wall from the left and right, and then the archers shot towards the iron armor wall in unison!

The iron shield wall composed of iron shield soldiers is constantly falling under the enemy's dense stone attack, and once a soldier falls, there are arrows shooting into the formation to shoot down other shield soldiers! But the Iron Shield Soldiers are still pushing forward!

"Sand! Sprinkle sand! ”

Xiahou Yuan roared, and the soldiers threw hundreds of bags of sand down from the city wall, the wind was not strong in the early morning, but the raised sand drilled into the eyes of the soldiers who climbed the city, violating their vision.

Most of the moving Iron Shield Soldiers were standing and walking with iron shields in both hands, but there was constantly sand drilling into their eyes from the gaps in the iron shields, disrupting their slogans, and slowly the slogans of the Iron Shield soldiers began to be chaotic and their steps were chaotic!

Finally, the Iron Shield cracked a big gap!

Xiahou Yuan seized the opportunity to make the archers shoot arrows! At one time, there were many casualties among the ironclad soldiers!

Gan Ning could only let the shield soldiers continue to make up for it, pushing the cart and continuing to move forward!

"Xiahou Yuan really has two hits!"

Ma Hong, who was watching the battle from afar, said to Pang Tong beside him.

Pang Tong nodded and said, "It's not easy to deal with!" ”

"Teacher! How did they defend the city with sand? The fox beside Ma Hong asked Ma Hong.

Ma Hong looked at the soldiers who kept falling, opened his mouth and said: "Fox Du, look at the blood of the soldiers, let me tell you, you listen carefully!"

"The students listened with blood."

"Where the smoke rushes, the ladders, and the law of the presence, the city must be used to protect it, and if it is insufficient, it will be made of wooden coffins. 100 steps to the left, 100 steps to the right, arrows, stones, sand, charcoal, rain, fire, water soup to help it. Ma Hong said.

"This is the seventy-first chapter of "Mozi", the method of defending the city described by Mozi, you have to study it carefully." Pang Tong accosted on the side.

"Look at it, I taught my disciple, but you interjected." Ma Hong looked at Pang Tongyi and said.

Pang Tong smiled and said: "Whether it is defending the city or attacking the city, you can't be cautious!" You see, although Xiahou Yuan is familiar with military books, he doesn't know the secrets of our rushing car, so he will definitely not be able to defend this city. ”

"Therefore, knowing oneself and knowing the other side can not be defeated in a hundred battles." Fox said.

"It is this reason that commanding the army cares about the word management, and information management is also extremely important!" Ma Hong Road.

Fox nodded.

Although some soldiers continued to fall, with nearly a thousand dead and wounded, in the end, the Iron Shield Soldiers still escorted ten rushing carts to approach the city gate! At this time, Xiahou Yuan ordered the soldiers to pour down the fire oil and splash it on the rushing car!

As soon as the shields arrived at the city gates, they all quickly retreated! Leave ten rushing chariots alone in front of the city gates!

"What's going on?" Xiahou Yuan was puzzled.

The fire oil is poured on the top of the rushing car, burning, and the more it burns, the more it burns!

Immediately after that, Gan Ning ordered the archers to fire rockets in front of the city gate!

Hundreds of rockets are coming! Dozens of barrels of fire oil were poured on the rushing car!

In a flash!

Boom Boom!

Then the flames fought! Less than five seconds of firelight! The gates of the city were blown to pieces! Smoke rises from the city gates! It spread rapidly upward, and in a short time, all the soldiers on the castle tower were buried in the smoke.

The soldiers who were close to the city gate were all blown away by the huge explosion, and Wei Yan, who was more than twenty meters away from the explosion, had already plugged his ears with a cloth, but the hot current rushed to his face full of heat.

The sound of crackling explosions continued to be heard in the thick smoke, and the upward heat sent everyone on the castle tower flying. Less than five minutes! The walls were covered in smoke, and there was no sound of ghosts crying and wolf roaring, for all the screams were muffled by the sound of the explosion.

Intense dazzling light! It appears white in the near area and golden in the distance. Xiahou Yuan, Zhang He, and Xun You stood far away from the city gate, but they were still almost overturned to the ground by this heat wave!

Ringing in my ears!

Boom Boom!

Hiss!

Chirping!

Cao Hong was behind the city gate, and was thrown out more than three meters away by this heat wave, his eyes were black, and he fainted on the ground!

An explosion! Let Cao Jun completely break the strings!

Shock in the smoke!

Struggle in the midst of the fire!

The city is broken!

So fast!

Xiahou Yuan couldn't believe it, and he didn't want to believe it, it seemed like a dream! But the pain on his face is so real.

"General, go! While! Xun Yu grabbed Xiahou Yuan and said loudly.

Xiahou Yuan's eyes were full of tears when he was smoky, and he roared unwillingly!

Thick smoke fills the castle towers! The Cao army on the city tower is scattered! Crowded with each other and constantly falling down the tower, countless people were killed and injured at one time.
