Ground floor.

In that huge chamber, Ling Cao was standing in the center, holding a torch aloft and sweeping around.

Around the whole chamber, densely covered with wooden pillars, close to more than 70 roots, down to the ground, up close to the top of the tong.

The roof of the cave above was trembling slightly, and dust was constantly falling, indicating that on the ground, the Wei army's divine thunder cannon was bombarding the city.

If it weren't for the support of those wooden pillars, with such loose soil as the Guanzhong Plain, such a huge chamber would have collapsed long ago.

Ling Cao brushed away the falling dust and looked back at the tunnel behind him, the footsteps in his ears were getting more and more urgent.

Suddenly, a Royal Forest sergeant rushed out from the other side of the tunnel and shouted, "General Ling, Your Majesty has an order, you can set the fire." ”

Ling Cao's eyes flashed, and he shouted, "Light the fire oil and burn the pillar for me." ”

When the order was passed, more than a dozen soldiers who were also holding torches high immediately set fire to the firewood, grass and oil piled up under each wooden pillar.

In the blink of an eye, a fire broke out in the chamber, and more than 70 wooden pillars supporting the roof were all ignited.

"Quick, get out of the tunnel!"

Ling Cao threw down the torch, turned his head and went back to the tunnel, running all the way, with more than a dozen soldiers following closely behind.

Thick black smoke followed behind them, gushing out all the way.

The front was getting brighter and brighter, and suddenly, Ling Cao jumped out of the hole, and his eyes suddenly brightened.

At this moment, he was already in a forest in the east of Chang'an City, standing here and looking northwest, only to see his hundreds of thousands of troops still confronting the Han army, and the loud roar of the divine thunder cannon was still deafening.

Ling Cao looked down at the entrance of the cave, and the thick choking black smoke was gushing out of the cave and rising into the sky.

A sneer rose at the corner of Ling Cao's mouth.

Wei army, the middle army array.

Su Zhe was still enjoying the grand occasion of the enemy city being bombed.

At this time, Xu Chu suddenly pointed to the northeast corner and said, "Your Majesty, look, the smoke is up, it must be Ling Cao that they have successfully set fire." ”

Su Zhe's eyes lit up, and he waved his hand and shouted: "Order, the Divine Thunder Cannon will stop bombarding." ”

The order was laid, the drums of war fell silent, and hundreds of divine thunder cannons stopped bombarding one after another.

The loud sound of the sky cracking finally stopped, and the heavens and the earth returned to calm.

Su Zhe looked at the head of Chang'an City, where the dust was gradually falling, with an expectant smile on his face, he didn't do anything, just waited silently.

Time passed minute by minute, and in the northeast, thick black smoke had risen into the sky, getting thicker and thicker.

Chang'an City Head.

Guan Yu and his Han army had returned from their thrilling moments, and they dared to stand up again, ready to meet the onslaught of the Wei army.

To their bewilderment, hundreds of thousands of Wei troops stood in the snow, neither attacking nor retreating, and there was not even a movement for a long time.

The Han soldiers looked at each other in a daze and confusion, and they were a little confused for a while, and they discussed in private.

"Su Zhe, no matter what tricks you play, you don't want to capture my Chang'an, I see what tricks you are doing." Guan Yu snorted coldly, the battle knife in his hand was clenched, and Danfeng's eyes were full of disdain.

At the bottom of the city, Liu Bei's gray face showed confusion and anxiety.

After the Wei army finished bombarding the city, it was supposed to take advantage of the situation to attack the city, but there was no movement for a long time, which made Liu Bei feel a sense of foreboding.

"Prime Minister, what do you say the thief is cheating, why doesn't he attack the city?" Liu Bei looked at Zhuge Liang with a confused and uneasy gaze.

Zhuge Liang's expression was also full of suspicion, but his eyes had already looked to the east of Chang'an City and noticed the black smoke rising from the pillar.

In his heart, he couldn't help but feel a strong sense of foreboding, and he always felt that Su Zhe was brewing some conspiracy.

"Su thief, what the hell do you want to do?"

Zhuge Liang frowned deeply, muttered to himself, and fought a deep cold war behind his back.

Thundered~~

There was a loud rumbling sound in his ears, and the ground under his feet suddenly shook and shook.

In front of him, the majestically standing east gate of Chang'an began to shake from side to side, and the ground under the city wall was rapidly cracking.

Bang bang bang!

Immediately afterwards, the large and large pieces of the wall were falling apart, and the ten zhang range centered on the city tower was sinking rapidly.

"What's going on, why did there be a sudden earthquake in a good way, what's going on?" Liu Bei was instantly panicked and discolored, losing his sense of proportion.

Zhuge Liang also opened his mouth slightly, looking at the incredible scene in front of him in surprise.

The east gate of Chang'an is collapsing!

Above the city wall, the screams and screams were already everywhere, and the Han soldiers were so frightened that they either grabbed the city wall and did not dare to move, or they fled towards the city with rolling belts.

Guan Yu supported the ground with a knife, barely stood still, and exclaimed: "What's the matter, could it be that Su thief who is making the demon magic work work again?" ”

Click!

At this moment, the city tower behind him suddenly made a loud noise, and the dilapidated city tower was actually split into two pieces from the middle and fell to both sides.

Guan Yu was shocked, and in a hurry, he did not flee to the city, but jumped on his horse and galloped along the city wall.

Along the way, the ground under his feet fell apart, quickly cracked and collapsed, the entire city wall collapsed and fell, screams kept ringing in his ears, and countless soldiers fell, either to their deaths, or to be squeezed into flesh by the broken stones.

Finally, the ground under his feet no longer cracked, and Guan Yu rushed out seven or eight steps before he restrained the war horse.

He looked back tremblingly, and was instantly stunned, and his body froze into ice.

The gates are gone!

To be precise, the city wall, which was centered on the east gate and was ten zhang long and wide, had collapsed into ruins, leaving only the dust and mist that diffused in the air.

Guan Yu's mouth was wide open, and his eyes were full of astonishment, as if he had seen the most incredible thing in the world, and he looked at the terrifying scene in front of him in despair.

The dust and mist gradually settled, and the majestic east gate of Chang'an had become a ruin, and countless remnants of the Han soldiers were squeezed in the cracks of the stones, crying out miserably for help.

The surviving Han soldiers, looking at this terrifying scene, everyone fell into terror.

Inside the city.

Liu Bei had already solidified into ice, and his pale face was distorted and deformed, replaced by endless consternation, and his eyes were as if he had seen a ghost.

Zhuge Liang, Sima Yi, Zhao Yun and other military generals were all stunned and ossified, and were replaced by endless horror and confusion.

"The city wall has collapsed, could it be that the thief made the magic work unsuccessful? It's impossible, even if the thief uses magic magic, it is impossible to collapse only such a city wall, and collapse so accurately? ”

Sima Yi was stunned and let out an unbelievable sigh.

Zhuge Liang looked carefully, but found that under the ruins, a pitch-black hollow was exposed, and his eyes rolled a few times, and he suddenly realized.

"The thief didn't use witchcraft, he sent someone to dig a tunnel secretly, dug under the city tower, dug a hole underneath, and then supported it with wood, and now he burned the pillar, the hole can't be supported, and it will collapse."

Zhuge Liang finally suddenly realized and understood Su Zhe's strategy, and the feather fan pointed to the northeast, "See that black smoke, those smoke are the smoke produced when the wooden pillars in the hollow are burning!" ”

Everyone looked shocked, and their stunned eyes seemed to be unable to believe that Su Zhe could come up with such a "ridiculous" plan.

This is a means of breaking the city that has never been done before!

"Since the thieves are digging tunnels, why are we all unaware?" Liu Bei, who came to his senses, gritted his teeth and asked.

Zhuge Liang smiled bitterly: "This is the reason why the Su thief has been bombarding us with divine thunder cannons for the past few days, he is not for attacking the city at all, but to use the loud sound of the bombardment to cover up the sound of the tunnel he is digging underneath." ”

Liu Bei's body was shocked, and he suddenly came to his senses, and the whole person fell into a state of astonishment and confusion.

Outside the city, Wei Array.

Hundreds of thousands of Wei soldiers witnessed this incredible scene, and they were all shocked and disgusted, and countless surprised eyes turned to their heavenly sons.

They couldn't imagine what means their god-like Son of Heaven used to make the impregnable wall of Chang'an collapse by itself.

After an uproar, there was a crazy joy, earth-shattering, and excitement.

"Your Majesty, I didn't expect that the old scorpion's strategy really worked, this is good, let's burn Chang'an City without much effort!" Yan Liang exclaimed excitedly.

The corners of Su Zhe's mouth raised a smile of relief, the murderous intent in his eyes was awe-inspiring, and the horsewhip pointed at the enemy city, and said sharply: "The city wall has been broken, what are you waiting for, raze Chang'an City to the ground for me!" ”
