Chang Zizi saw the fiasco of Luo Muyun's forward army, and he felt a burst of ecstasy in his heart, I couldn't imagine that you Luo Muyun also had today!

Enemy camp.

Seeing that the enemy army was defeated, Curse Blue immediately led his army to cross the path between the two high grounds, and approached Roselle City.

"The generals listen to the order, if anyone can take off Luo Muyun's head today, I will embrace him as the former general in front of the Holy Lord, with a reward of one million and a seal of ten thousand households!"

Curse Blue didn't expect that this battle would be so smooth, according to the previous battle plan, attack Roselle City, and lead other defending troops in the Western Regions to come to support, at that time, the army ambushed near the other eight cities will directly break the city! If you don't come to the rescue of Roselle City, with the 100,000 army of Curse Blue, it is enough to make Roselle City suffer a devastating blow!

In addition, the curse blue they also have a purpose, which is to cover for the Sword Immortal Family and give them enough time to fight against the Luo Shen Family, compared to one city and one pool, Neiying is still the most important!

In the battle on the highlands just now, Luo Muyun's side lost nearly 15,000 people, while Curse Blue only lost 1,000 or 2,000 people.

Soon, a group of cavalry rushed over the high ground and entered a pothole at the front.

When these cavalrymen landed, they stepped on the pit and immediately splashed a lot of liquid.

The liquid came into contact with the air, and with a pop, spontaneous combustion occurred, and in an instant a sea of fire was formed, and the cavalry who rushed to the front. Screaming in the sea of fire, the fire spread, engulfing at least hundreds of cavalry in an instant.

This is not an ordinary flame, and ordinary flames can't cause much damage to silver-level martial artists. What Yu Fei poured into those potholes was black oil, and these black oils were also added with phosphorite and other substances, which would burn when it touched the air, and the burning was so hot that ordinary water could not extinguish it.

When the cavalry marched, the cavalry in front could not stop at all, and one by one they were rushed into the fire by the cavalry behind, which made the fire even more vigorous, and the horses were frightened, and the soldiers fell off their horses one after another, although they would not cause any substantial damage, but they would make their troops discouraged.

In just a few moments, the enemy lost thousands of cavalry!

In just an instant, he killed thousands of silver-level martial artists!

This scene shocked everyone, and no one could have imagined that the liquid poured into those depressions. It had such a terrifying power that it blocked the enemy's cavalry offensive at once.

At this time, Luo Muyun, Shangguan Yun and the others were also slightly stunned for a few seconds, and then showed a little joy, I don't know what kind of liquid Yu Fei is configured, but this is definitely a sharp weapon against the enemy cavalry!

"Yu Fei, this kid really has a hand, just this trick saves us a lot of effort!" Shangguan Yun said excitedly.

Luo Muyun's eyes also showed a bit of appreciation, Yu Fei did a good job.

Chang Zizi's face became gloomy. He didn't expect that the attack of the army would be blocked all at once.

"Look over there!" shouted one of the city guards.

Everyone looked into the distance, and saw that after the first wave of the enemy attack was blocked, they quickly divided into two groups, bypassing the sea of fire and charging on both sides.

"No, in that case, the enemy will charge the south and north sides of the city, where the walls are weakly guarded. One of the elders of the Roselle family's face changed slightly.

At this moment, I saw Luo Fan leading the army to rush out of the south gate and take the lead, fusing the demon demon dragon martial spirit, two golden flames, drawing two parabolas in the darkness, and in an instant, the two fire dragons have been spreading towards distant places, forming two blazing walls of fire, which are five or six meters high and stretch for thousands of meters.

Some of the cavalry rushed too fast to stop, rushed through the wall of fire, and immediately let out a terrible scream, their whole bodies burned, staggered out dozens of meters, and finally fell to the ground in scorched black. One by one, the cavalry could not stop rushing into the wall of fire, and a moment later hundreds of cavalrymen died in the flames.

At the same time, Gongsun Zhanfeng led the army to rush out of the north gate, a little silver light arrived first, and then the gun came out like a dragon, picking up dozens of golden warriors, and then fused with the martial soul of the armored dragon, a earth-shaking tail hammer, which made a roaring sound in the air, and the ground shattered dozens of meters of land, and the horse was frightened and retreated!

Under the pressure of the two generals, Luo Fan and Gongsun Zhanfeng, these enemy troops continued to storm the western wall of Luo Shen City.

All this seems to be good, Yu Fei and Luo Muyun tacitly know it!

"It's almost time to reach the second line of defense!" Yu Fei smiled at the corner of his mouth, everything was just as he expected.

From the army's marching route and combat methods, Yu Fei can see that the enemy commander was a little proud in the battle on the high ground just now, and he actually charged with cavalry, which was really a taboo for soldiers.

Generally speaking, cavalry, as the most mobile type of troops, is often used as a surprise attack in siege warfare, and the infantry and city vehicles are the main force, and they actually let the cavalry as the main force of the siege, which is really a taboo for soldiers!

Secondly, if the ladder necessary for the siege is blocked by the first line of defense, the army should be ordered to rest, clear the road obstacles, and use catapults, ballistas, and crossbowmen to cover the infantry to push the ladder to the city safely!

So, Yu Fei told Luo Muyun about this idea!

Luo Muyun thought for a while and said, "Okay! ”

At this time, Luo Fan, Gongsun Zhan, Zhuge Yan, Zhuge Xin'er and the four generals of the field guard battalion came to Luo Muyun.

"The four generals of the wind, forest, fire, and mountain obey the order, and I order the four of you to lead six thousand light cavalry to destroy the enemy's ladder out of the clouds, and make the merit for the crime!" Luo Muyun ordered.

"Yes!" the four generals quickly gathered their men and horses and went out of the city to destroy the enemy's ladder of the clouds, and the archers on the city walls covered them!

At the same time, Luo Muyun called Luo Fan and Gongsun Zhanfeng to his ears, said a few words, and the two left in a hurry.

Chang Zizi was a little puzzled, what kind of medicine is sold in this Luo Muyun gourd?

And Yu Fei, who was standing on the side, seemed to understand something, called Zhuge Yan and Zhuge Xin'er to him, and whispered a few words.

"Ah, Your Highness, is this really the case?" asked Zhuge Xin'er in a low voice.

"Talk less, do more!"

Hearing Yu Fei say this, Zhuge Yan and Zhuge Xin'er didn't say anything more, "Yes!"

Chang Zizi looked at Yu Fei, his heart was full of disdain, how much ability a little kid can have!

Boom Boom!

The sound of a sharp explosion, like thunder and lightning whistling in their ears, even the people standing on the city wall couldn't help but cover their ears, the sound was simply terrifying.

The scene ahead is even more shocking.

Thousands of chain explosions, those cavalry who rushed in front were blown up in an instant, and many enemy troops were directly torn to pieces, turning into broken pieces of flesh flying all over the sky.

With this explosion, at least a thousand cavalry were wiped out in an instant, even including some of its gold-level martial artists and several platinum-level martial artists.

The previous sea of fire made Luo Muyun, Luo Fan and the others only slightly surprised, but now, they were completely shocked.

This explosion was really terrifying! Even the platinum-level warriors were torn to shreds!

"Yu Fei, that kid, what exactly did you use?" Luo Muyun said with palpitations.

At this time, Chang Zizi was even more frightened, this chain explosion was really terrifying, if you didn't guard against it, if you accidentally made a secret calculation, I am afraid that the entire Sword Immortal family will have to fly!

Yu Fei asked the Pill Medicine Master to arrange more than 20 kinds of ores and herbs such as phosphostone and black chips together to make liquids, which were packed in iron, these liquids were extremely unstable, and slowly had some kind of slow chemical reaction with iron, and after being violently impacted, a large explosion would occur, and the power of the explosion could definitely be described as devastating.

Two or three thousand enemy cavalry were killed without close hand-to-hand combat, which was enough to make Roselle City lose many people! Especially since there were a few platinum-level warriors in between, it was an absolutely terrifying existence!

The explosion was so terrifying that the cavalry behind them were afraid and retreated, but the commander behind ordered not to retreat, and he killed several retreating soldiers one after another to deter.

The enemy did not dare to disobey and gritted his teeth and continued to advance.

Boom Boom!

Several explosions occurred one after another, knocking over dozens of cavalrymen.

This dare is to let the cavalry be cannon fodder!

The tens of thousands of troops continued to move forward, approaching in the direction of Roselle City, although the speed was much slower, but the number was still terrifying.

At this time, the four generals of Wind, Forest, Fire and Mountain led 6,000 light cavalry to go around from the south gate to the vicinity of the enemy's cloud ladder, and launched a fierce attack on the cloud ladder, thousands of arrows with fire pierced the night sky and shot at the cloud ladder, and the enemy's rear was full of fire.

When Curse Blue's subordinates saw it, they were very frightened, "General, there is an enemy attack in the rear!"

The corners of Curse Blue's mouth raised slightly, and he said, "The fish has finally bitten the hook!" Listen to the order, the forward troops stop attacking and fight back against the enemy!"

"Yes!"

After completing the task, the four generals of the Wind Forest Volcano were about to retreat, but suddenly, there were flames all around them, and they were surrounded, and the leader was the fire god Romixiu!

How terrifying Rometheus is, these four generals know it, and in the rear, the curse blue cavalry is coming!
