Several fluorescent spells quickly drilled into the fire separation array at the back door, and the ten fire separation arrays suddenly shone brightly, and the flames erupted in an instant.

Intense pillars of flame light erupted rapidly from the fire array on the city wall, instantly engulfing all the enemy troops in front of the city wall, and before they could react, they were already flying into ashes.

The powerful reaction brought by the ten fire arrays made the back door of Changxiang City tremble slightly, and fine cracks appeared in the brick and wood city walls, faintly threatening to collapse.

"Quick! get down the city wall!" Huang Yuchen shouted, no longer looking at the effect of the fire array, and with a strong step, he rushed down from the city wall, mounted his war horse, and galloped quickly in the direction of the front door.

The remaining defensive sergeants on the city wall also immediately withdrew from the back gate city wall, and they all brought their cavalry equipment, near the back gate city wall, lined up in a neat formation, if the back door was destroyed by the reaction brought by the fire array, they would rush out as soon as possible, and annihilate the third camp left by the enemy.

The two hundred people in the city were also notified by the sergeant at the back gate, and they went out one after another and rode on the war horses prepared for them, which were all war horses of soldiers who had died in the defensive battle. The people rode on broad horses, trembling, clutching at the reins.

Huang Yuchen rode on the horse, extremely fast, and a little anxious in his heart.

The battle at the back gate has been so fierce, there are only less than 10,000 enemy troops attacking the city, the front gate is even wider, and the number of attacking enemy troops is several times that of the back gate.

The speed was extremely fast, and it didn't take long for Huang Yuchen to come to the front gate city wall. Deafening shouts filled the night sky, and all the sergeants climbed the walls and threw themselves into the defense of the front gate. Huang Yuchen didn't stop, turned over and dismounted, and came to the front door in a few steps.

Standing on the city wall, he saw the tragedy of the battlefield in front of him.

The two towers have been destroyed, and many enemy corpses have been left on the top of the city, and several of their own soldiers have fallen in pools of blood. Under the city wall, a rushing cart has been destroyed, countless enemy soldiers have died, more than 5,000 enemy troops in the first phalanx have been exhausted at this moment, and the enemy troops in the second phalanx are advancing. Four trebuchets have been erected and boulders are being placed.

didn't have time to look more, Yu Sheng saw Huang Yuchen ascend to the top of the city, and immediately shouted anxiously at Huang Yuchen: "Activate the formation!"

Huang Yuchen did not hesitate for a moment, and immediately engraved a spell in the air, and ten talismans emitting pale yellow fluorescence appeared in the air in an instant. I saw Huang Yuchen's eyes condensed, his hands waved, and he shouted: "Leave the fire array, Qi!"

The ten spells turned into ten yellow rays of light, and quickly burrowed into the fire array above the city walls and gates.

In an instant, the flames soared into the sky, engulfing everything in front of them.

"Boom!"

The enemy's trebuchet, at the same time as the fire array was activated, launched an attack, and the huge stones were thrown high and headed straight for the city of Changxiang. smashed into the city of Changxiang, and several houses collapsed in response.

"Get out of the city!" Yu Sheng saw that the fire formation had been opened, and immediately ordered. All the sergeants acted instantaneously and quickly evacuated the walls.

The horses were ready before the battle, and all the sergeants mounted on their horses and quickly assembled in the direction of the back door.

"Boom, boom!" The four trebuchets kept firing, and several boulders frantically attacked the front gate of Changxiang City. About ten zhang near the front door, it has become a barren land, and there is no life within the flame range of the fire array.

Shen Tu was anxious to scold in the camp, but he was helpless, just as he thought. In the face of absolute strength, the number of people does not necessarily have an advantage.

The sky-high fires on the hills on both sides, coupled with the fire at the front and back gates of Changxiang City, for a while, Changxiang City seemed to turn into a sea of fire. The intense light of the fire illuminated the night sky, as bright as day.

Huang Yuchen rode on a horse, followed Yu Sheng, and quickly walked towards the back door, until now, he finally understood Yu Sheng's intentions, from the very beginning, he did not plan to fight to the death with the enemy, but put on a death battle, forcing the enemy army to send a large number of surrounding soldiers to besiege Changxiang City, in this way, the black armor iron cavalry needs to face half of the enemy army at most, and in the siege battle, the enemy army must also have attrition, and when it is time to break through, the number of enemy troops must not even be half of the total.

This strategy for the rest of his life had an unexpected effect, not only did the enemy send so many soldiers to besiege Changxiang City, but also made the soldiers at the gates on both sides of Changxiang City unbalanced in the final battle. In this way, all the sergeants concentrated their forces to break through the rear gate and face only the enemy's phalanx of 3,000 men, which was countless times easier than facing 60,000 men.

"Boom!"

Yu Sheng rushed to the back door with a large group of people, but suddenly heard a deafening sound in front of him, and sped up his horse to take a look, but saw a huge gap in the back gate city wall. Left and right of the gap, the pillar of light from the fire array has not disappeared, but the fire array above this gap has destroyed the integrity of the spell due to the shattering of the city wall, and the pillar of fire from the fire array has disappeared.

Yu Sheng rode his horse and came to the back door, and the sergeant behind him spontaneously lined up near the back door, facing the gap that appeared on the back door. Huang Yuchen looked left and right, and saw that the guard, who had been seriously injured and dying, was tightly tied to a war horse, led by a centurion, and followed behind the team. All the sergeants were silent, and the fire, reflected in their eyes, sparkled.

The raging fire emitted from the fire array was still burning, and it was so far away that it could already catch up with the monstrous heat wave, hitting the face, and there was a slight burning sensation.

Yu Sheng narrowed his eyes, looked through the gap in front of him, and looked at the phalanx of the enemy army in the distance, his eyes were cold.

In a moment, the power of the fire array at the back door was exhausted, and the power of the flame slowly extinguished.

"Kill!"

At the moment when the flames were extinguished, Yu Sheng ordered loudly, instantly urging the war horse to rush out towards the gap that appeared on the wall of the back gate.

All the sergeants behind him immediately responded, followed the footsteps of Yu Sheng, urged the war horses, and quickly rushed out from the gap in the back gate wall.

The crack in the wall of the back gate does not look big, but it is enough for several knights to rush out side by side. For a while, the sound of horses' hooves sounded, and the black-armored iron horseman, reflecting the sky-high fire, stepped over the charred ground in front of him, and quickly rushed to the enemy phalanx not far ahead.

Huang Yuchen sat on the war horse, holding the cavalry's standard halberd tightly in his hand, clamping the horse's belly, and rushing towards the enemy with the fastest speed. At this moment, he has only one thought in his heart, kill!

Rush into the enemy's formation, desperately kill the enemy, kill a few, just a few, and vent the anger in your heart wantonly.

In fact, at the back gate of Changxiang City, the remaining 3,000 sergeants were stunned by the sudden fierce flames after seeing the ten fire formations activate at the same time. Including their commanders, they were no longer combat-powered.

They couldn't imagine that after such a long period of tragic fighting, the Dongwangfu Army in Changxiang City still had such a killer weapon. They couldn't imagine that after the fierce flames brought by this formation, the enemy's iron cavalry was killed in front of them.

In the face of this loose enemy phalanx, the enemy sergeants who had long lost their fighting spirit. The black-armored iron cavalry of the Eastern Palace, like a wolf and a tiger, rushed into the enemy formation, like a sharp knife inserted into the tofu. Without encountering any decent resistance, the black-armored iron cavalry team quickly broke through the enemy's phalanx, followed the official road at the back gate of Changxiang City, and left in the dust.

And this time it was killed, the enemy army was 3,000 people, and more than half of them were lost.

For the rest of his life, with a kind of sergeant, he walked along the official road at the back gate of Changxiang City, and left without dust, behind them, there was a sea of fire, Changxiang City, shrouded in this sea of fire. From a distance, the current Changxiang City looks like a fire dragon hovering in the dark night, hideous and terrifying.

Changxiang City, front door.

The pillar of light from the fire array slowly disappeared, and the front door was about ten feet away, and it was a charred black. The corpses and weapons of war that had been in the square disappeared without a trace.

On the city wall, there was not a single defender in sight, and even the banner of the East Wangfu disappeared at the same time.

When Shen Tuyan saw this, he jumped like thunder, and immediately ordered all the sergeants to attack and rush to the city wall.

Soon, a whole formation of enclave sergeants advanced under the gate of Changxiang City without resistance, and with the help of the rushing car, the main gate of Changxiang City was opened without much effort.

The city of Changxiang was empty.

When Shen Tuyan entered Changxiang City, he saw the situation inside Changxiang City, and the mania and anger in his heart reached a peak.

There is no doubt that Changxiang City is an empty city. At this moment, the few houses in the city were also smashed by the huge stones of the trebuchet, and there was not a single defender in the entire city, where was there still a trace of the Dongwangfu army.

Shen Tuyan came to the back gate of Changxiang City, looked at a gap in the city wall, and was stunned.

The power of the fire array at the front door is no worse than that at the back door, how Changxiang City was built, Shen Tuyan naturally knows. But why is the wall of the front gate not damaged, but there is such a big gap in the back door.

stepped forward to take a closer look, and Shen Tuyan found that near this gap, the defenders of the Dongwang Mansion had already moved their hands and feet, and this city wall close to the edge, not to mention the formation reaction, could be pushed by just a few sergeants.

Seeing now, Shen Tuyan knew that he had been completely defeated.

Later, before going to Wufeng City, take the official road, and there are two cities, and the defenders in these two cities, combined, may be less than a thousand. With the combat effectiveness of the soldiers of the Eastern Palace, these people were simply vulnerable.

The operation of sniping the Dongwangfu army was a complete failure. But Shen Tuyan was not alarmed, he immediately ordered to gather his army and quickly rush to the next city.

If he suddenly joins the battle at the moment when the Dongwangfu army and the defenders near Wufeng City are fighting, and finally wins, he will still have a chance to defend himself. After taking the East Palace, his position of power can not be threatened.

Running wildly on the official road, all the war horses took steps and galloped quickly. After a few days of fighting, the war horse has not been consumed, and at this moment it is running, full of endurance.
