The back of Dingjun Mountain.

Five hundred Wei soldiers, under the leadership of Deng Ai, secretly slipped behind Dingjun Mountain under the cover of night.

Due to Wei Yan's attack, the attention of the Han army was attracted to Dingjun Shanxi, and Deng Ai and his five hundred soldiers were able to hide from the eyes and ears of the Han army, and they touched here unconsciously.

Brushing aside the last branch, Deng Ai finally walked out of the woods, raised his head and looked up, and couldn't help but take a cool breath.

I saw a hundred-foot-high slashing wall, like a giant sword inserted into the ground, lying in front of Deng Ai's eyes.

Such a steep mountain wall, almost vertical, and the mountain wall is so smooth that even the most seasoned hunter is afraid that he has no ability, let alone the courage to climb the cliff.

"Your Majesty is right, this Dingjun Mountain really only has one side to attack, and the other three sides are birds that can't fly up......"

Deng Ai took a breath and secretly sighed in his heart.

He listened with his ears pricked up, and the sound of killing was faintly coming from the west side of the mountain, indicating that a fierce offensive and defensive battle was still going on to the death.

It was Wei Yanzheng leading 10,000 Wei troops, storming the camp of Guan Yu, so as to contain Guan Yu's attention and win a precious gap for him.

"I'm afraid that Wei Wenchang won't be able to support it for long, so I have to hurry......"

Deng Ai thought about it for a moment, and immediately turned around and shouted: "Brothers, be sharp, hold up the Kong Ming lantern for me!" ”

When the order was passed, the five hundred soldiers immediately got busy, found an open space, and unloaded all the parts of the Kong Ming lantern they were carrying and reassembled them.

In the blink of an eye, more than 20 Kong Ming lanterns were assembled.

The fire oil was lit, and the collapsed Kong Ming lanterns were soon blown into balls by the heat, and slowly rose into the air, if they were not bound by ropes, they would have risen directly into the sky.

Deng Ai took a deep breath, jumped on the hanger of a Kong Ming lantern, and shouted: "According to the detachment in advance, immediately get on the Kong Ming lantern." ”

The order was handed down, and more than 200 soldiers immediately boarded the Kong Ming lantern and firmly grasped the rope.

The rest of the soldiers untied the towing rope and slowly relaxed, so that one by one, the Kong Ming lanterns, almost against the mountain wall, slowly rose into the sky and drifted towards Dingjun Mountain.

Deng Ai clutched the rope tightly, he didn't dare to take a breath, and as the height continued to rise, the cold sweat on his forehead also rolled straight away.

When he reached the halfway point of the mountain, he couldn't restrain his curiosity, glanced at his feet, and couldn't help but gasp.

"This Kong Ming lantern is really magical, it can send people so high, I only flew dozens of zhang and I was so panicked, I really don't know how terrifying the height of Wei Wenchang and them went to attack Yinping City in the clouds......"

Deng Ai sighed in his heart, and didn't dare to look down anymore, only raised his head and stared at the top of the mountain.

As the height rose, finally, the Kong Ming lantern rose to a flush height at the top of the mountain.

Deng Ai quickly lit a fire stick and threw it from a high altitude, and the soldiers below saw the signal and stopped continuing to release the rope, allowing the Kong Ming lantern to remain suspended and unmoving.

Deng Ai grabbed the flying hook, aimed at a big tree at the edge of the mountain, and threw it out with a whoosh.

The flying hook was impartial and firmly grasped the trunk of the tree, and Deng Ai pulled the hook rope, dragging the Kong Ming lantern to sway, and kept approaching the mountain wall.

When the hanger was only one step away from the top of the mountain, Deng Ai jumped over, and the remaining nine soldiers on the hanger also jumped off the Kong Ming lantern one after another and landed steadily on the top of the mountain.

When they landed, everyone exhaled a long sigh of relief, as if they had experienced the most thrilling experience in their lives.

He glanced down at the bottom of the mountain, because it was dim at night, and the bottom was deep, and it was dizzying to look at.

Deng Ai calmed down, and on the one hand ordered the soldiers who had reached the summit to quickly build positions and fortifications on the top of the mountain, and on the other hand, he ordered the follow-up soldiers to follow.

After being busy for nearly half an hour, in addition to the more than 50 soldiers who stayed at the foot of the mountain, nearly 450 Wei troops all climbed to the top of the mountain.

In addition to the soldiers, there were nearly 10,000 rockets and more than 10 barrels of oil, all of which were transported to the top of the mountain with Kong Ming lanterns.

Deng Ai stood on the inside of the mountain, looked down the mountain, and saw that halfway up the hill, countless figures were crowded on the front line of the camp wall and fighting fiercely, and the earth-shattering killing sound was clearly heard on the top of the mountain.

"Your Majesty is really like a god, Guan Yu is defenseless......" A sneer rolled into the corner of Deng Ai's mouth.

This is Su Zhe's whole plan.

Through the quantum meteorological satellite, Su Zhe saw that the terrain of Dingjun Mountain was rising gently on one side, and almost vertical on the other three sides.

Therefore, Su Zhe judged that under this kind of terrain, Guan Yu would definitely concentrate all his forces on the halfway slope to defend, and would never be on guard against the top of the mountain.

Su Zhe then told Wei Yan and Deng Aibing to divide into two routes, one was Wei Yan to lead the army and launch a frontal attack on the Han camp to attract Guan Yu's attention.

The other road was led by Deng Ai, who rose from the back of the mountain to the top of the mountain with Kong Ming lanterns, and unexpectedly occupied the commanding heights of Dingjun Mountain.

Then, the Wei army could echo each other from afar, attack from high and low, break through the Han army on the slope of the mountain in one fell swoop, and seize control of Dingjun Mountain.

Now, Deng Ai has successfully climbed to the top of the mountain, and the Han army has no defense, everything is expected by Su Zhe.

"Brothers, light up the rocket!" Deng Ai raised the bow and arrow in his hand and shouted loudly.

When the order was passed, more than 450 Wei soldiers quickly bent their bows and put sharp arrows wrapped in oilcloth on the strong bows.

These four hundred and fifty Wei pawns were carefully selected by Su Zhe for Deng Ai, and all of them were elites who were good at shooting.

The arrow is already on the bow!

"Ignition!" Deng Ai shouted again, leaned over and stretched the arrow to the brazier in front of him.

The rest of the Wei soldiers quickly poked the arrows towards the brazier, and immediately lit the oilcloth wrapped in the arrows.

"Raise your bow!"

The order was given again, and four hundred and fifty sharp arrows were aimed at the sky.

"Shoot the arrows!" Deng Ai suddenly let out a loud shout, and the fingertips that drew the bow were loosened.

Woo!

A rocket broke through the air.

More than 400 soldiers let go one after another, and more than 400 rockets, like flying fire meteors, swept through the sprawling arc and roared towards the Han camp on the slope of the mountain.

Hillside, Han Camp.

Guan Yu and his 10,000 soldiers were all crowded on the front line of the camp wall, and the hinterland of the camp was basically undefended, like an empty camp.

Guan Yu stroked his beautiful hair, sarcastically and proudly admiring the fierce battle in front of him, and the corners of his mouth gradually hooked a sneer that was bound to win.

He had already seen that the Wei army's offensive had reached the end of a strong crossbow, and it could not hold out for a quarter of an hour at most, so he exhausted his sharp energy and had to withdraw from the attack.

At that time, he could take advantage of the situation to wave his army out of the camp, kill in one go, and break the Wei army.

In Guan Yu's mind, a happy picture of him personally beheading Wei Yan off his horse had even emerged.

"Rockets, there are rockets shot down on Dingjun Mountain!"

Just when Guan Yu was smug, a frightened scream suddenly sounded behind him.

Guan Yu's figure shook slightly, and almost instinctively turned around, looking up at Dingjun Mountain.

In an instant, Guan Yu's red face changed color in astonishment.
