Spread out the map, from Yanshi City to Luoyang, there are a total of 7 passes, and each pass is stationed with a commander to defend Luoyang.

And now, these passes have become an obstacle to continuously blocking Ma Chao, Liu Xie and others from entering Luoyang.

After crossing the first three passes, which were full of dead bodies, it was immediately discovered that from the fourth pass, there was another garrison inside.

It's just that when Ma Chao saw the "cow" flag planted in the gate tower of Guankou City, his eyes trembled, but he didn't expect that it had been occupied by Dong Zhuo's son-in-law Niu Fu.

Zhu Jun's retreat has been cut off by Niu Fu, so where is Zhu Jun and his main army?

The more he thought about it, the more he felt that it was not good, and the brothers Zhu Fu and Zhu Hao beside him also noticed that something was wrong, and couldn't help but look at Ma Chao, waiting for him to make an idea.

Xu Shu took a step forward and said: "General Ma, in today's plan, our army must quickly break through the pass in front of us, capture the defender and ask how the battle is going, so as to decide what to do next." ”

Ma Chao nodded, and then launched a strong attack on the pass.

The fourth pass is located on the path between two towering cliffs.

The city is more than ten zhang high, the city wall is thick, and there are countless arrow holes in the wall battlements, which are used for crossbowmen to shoot in them, and can protect the safety of crossbowmen to the greatest extent.

Ma Chaojun is all cavalry, and most of them are rogues and horse thieves obtained by Zhao'an, and their combat effectiveness is terrible.

After several fierce attacks in a row, they couldn't even go up to the wall, so they had to hurriedly withdraw from the archers' firing range.

"Hahahaha!"

On the wall of the pass, several guards laughed wildly, and some people joked: "The army outside the pass is really a group of strange people, I don't know what is in my head, and I actually use cavalry to fight the pass!" ”

"Hahaha, yes, that's interesting!"

The guard general shouted loudly: "Listen to the men and horses below, we are the troops of the general of the chariot and cavalry, Niu Fu, you know each other, hurry up and get out of Lao Tzu!" ”

"Damn!" When Gao Shun heard this, he was about to lead the army to attack the city again, but was stopped by Xu Shu and said: "General Gao, the composition of our army is too chaotic to attack at all, so we can only attack it with a strategy." ”

Ma Chao asked: "How to use the meter?" ”

Xu Shu said: "Xu has explored the terrain of this cliff, our army is all gathered on the path between the cliffs, not to mention the siege is not effective, even if the other party suddenly opens the gate of the pass and uses infantry to attack our army, it is difficult for our army to give full play to the advantages of cavalry." ”

He pointed to the two cliffs on the map, and paddled along the cliffs with his fingers to both sides of the pass, and said: "I am willing to lead the ranger troops, climb to the top of the cliff, and then sneak along the edge of the cliff to both sides of the pass, and then condescendingly, the defenders in the shooter, so that the opponent's army is shaken." ”

It turned out that Xu Shu meant this, and Ma Chao was overjoyed: "As long as the ranger troops can contain the strength of the defenders and successfully distract their attention, our army will start to attack again, and with a two-pronged approach, we will definitely be able to break through the pass!" ”

Xu Shu nodded and said respectfully: "Xu will go here." ”

"Wait."

Ma Chao suddenly shouted to Xu Shu, and said worriedly: "I look at the cliff with a height of dozens of zhang, even if someone with good skills climbs up, he will lose his life if he is not careful, why should you take the risk yourself?" ”

"What's more, your serious injuries haven't healed, so it's better to ask Adi and them to go."

Knowing that Ma Chao cared about him, Xu Shu shook his head lightly and said: "The plan of the surprise attack lies in a quick solution, in the entire ranger team, I am the only one, I can observe the situation and respond on the spot, Xu, I have to go!" ”

With that, he bowed his hand, and strode away, organizing all the rangers to assemble, take all the equipment, and begin to climb the cliff.

It took Xu Shu and the rangers more than half an hour to finally climb to the top of the cliff, panting one by one.

The cliff is too high, even if the rangers have light skills and excellent skills, it is difficult to hold on for a long time.

Fortunately, Ma Chao's trip to Yuzhou got Xu Shu and his ranger troops, otherwise the cavalry under Ma Chao's hands, even if they could force the pass, the casualties would be too great to continue to attack the next pass.

After resting, Adi looked around and asked, "Brother Xu, what should we do next?" ”

Xu Shu opened the map, compared the distance and route, and said, "Follow me." ”

A group of hundreds of rangers galloped along the cliffs on both sides.

In a short time, they had arrived on both sides of the pass, looked at the situation of the pass below, and found that the defenders of the pass had set up a total of three large camps in the front, middle and rear.

In addition to the three main camps, there are four watchtowers for observing the situation on the cliffs.

Xu Shu signaled to the rangers on the other side of the cliff, and everyone drew their short bows and quickly shot at the defenders on the guard tower.

Then, they lit the rockets, all of them pulled their bowstrings, and shot at the pass.

"Where did the rockets come from?"

The defenders looked at each other, and there was no alarm on the watchtower, so they had no way to look for the rocket, so they could only immediately draw water and quickly extinguish the flames of the rocket.

Dozens of rangers slid down the hillside, into the watchtower, lit torches wrapped in oil, and threw them down.

As soon as the oil on the torch touched the rocket, it immediately ignited a fire, and many of the defenders were stained with the oil and were engulfed by the raging fire in an instant.

Rumble!

The fire erupted suddenly and violently, and the defenders were in disarray, and shouts were everywhere.

"On it!"

The defenders shouted for a while, drew their bows and arrows, and kept shooting at the rangers hiding in the watchtowers, and both sides shot at each other, killing many people.

"Rush!"

A ranger drew his sword, jumped to the top of the pass, moved along the corner, and then jumped down from the corner and slashed the defender with a sword.

The two sides exchanged troops and fought everywhere, and the rangers did not forget to light torches and throw them everywhere, causing greater movement.

"Who is it?!"

The pass guards went out and killed a ranger with one shot, and then ran wildly, threw themselves into the ranger, and slaughtered for a while.

Xu Shu looked at each other angrily, struck with his sword, and fought with the guards, and there were shouts of killing everywhere in the pass, and the temperature in the air was getting higher and higher, and a trace of sparks suddenly appeared in the air.

"Ahh

"Help me, help me!"

The sparks in the air fell to the ground, and suddenly a fire burst into flames, and more and more defenders were covered in flames, and they ran wildly in all directions, trying to find someone to help them extinguish the flames on their bodies.

There was a very strange situation, even those defenders who were not stained with fire oil would inexplicably burn.

As a result, the three barracks were engulfed in flames in just a moment.

Adi, who was still fighting with the defenders, was stunned, why didn't he understand that his own torches were so powerful?

Xu Shu's brows furrowed suddenly, as if he remembered something, and immediately ordered: "Retreat!" ”

"It's getting better and better away from the defenders!"

"Brothers, get out!"

Signaling the other rangers to retreat, they immediately retreated, climbed back up the cliff along the watchtower, and sat back to watch the fire in the pass.

On the other side, the fire in the gate was soaring, Ma Chao knew that Xu Shu had succeeded, and when he was about to attack the city, a fire suddenly fell from high in the sky!

Boom bang!!

The cliff was blasted by the firelight, and the flying rocks rolled down and smashed into the pass.

Countless defenders were smashed into meat sauce by rubble before they were burned to death.
