The death of Lu Bu, Yan Liang, Wen Chou, and Zhang Fei, only Ding Yuan was angry in the princes' coalition, and the others were indifferent, because they knew that the final result was ninety-five percent like this, they had already guessed it, only Ding Yuan, a fool, had not thought about Liu Bei's final meaning, Ding Yuan had lost Lu Bu's status and immediately declined, he silently proposed to retreat, Yuan Shao promised him, anyway, it was useless for Ding Yuan to keep it now, and the people he brought were only 50,000 people, and these 50,000 people had no effect except to be cannon fodder.

A few days have passed, and Yuan Shao has not sent troops to die in these days, he is trying to find a way to restrain the shells, so he has thought of a way.

A few days later, Liu Yi also rushed to Yangyi Pass from the Western Regions, and learned that Guan Yu had killed Lu Bu, Yan Liang, Wen Chou, and Zhang Fei, Liu Yi was very happy, although these people did not pose a threat in front of the guns, but fate was uncertain, maybe there would be an opportunity for them to give Liu Yi a fatal blow, and now killing them is really in addition to the four sudden catastrophes in fate.

"Second brother! Has Yuan Shao moved in the past few days? Liu Yi stood on the city wall and looked at the outline of the military camp in the distance and asked Guan Yu.

"Big brother! It's strange that they haven't been moving any time lately! Normally, they come every day to deliver thousands of lives! Guan Yu was also puzzled that Yuan Shao would not come to attack the city.

"Night! Send me a mortar team of 10,000 people! They don't come, I come! Liu Yi said with a smile.

"Yes!"

In the evening, Liu Yi quietly took 10,000 people to the vicinity of Yuan Shao's camp, and the soldiers in Yuan Shao's camp were eating dinner at this time.

"Assemble the mortar! Get ready to fire shells! Liu Yi picked up the mortar barrel and assembled it, and today he also wanted to try the feeling of playing with artillery abuse.

Soon, the assembly of 5,000 mortars was completed, Liu Yi took the lead in loading shells, and then 5,000 mortars were loaded with shells.

"Bang bang bang!" The shell slid down the barrel to the bottom and hit the thimble, and then fired.

"Boom, boom, boom!" Yuan Shao's camp was blown up by the cannonballs in an instant, and the soldiers who were still eating were blown to pieces, and for a while Yuan Shao's barracks were in chaos, some ran away with food and swore to protect the food, some were eating wildly and were ready to accept death as a full ghost, and there were those who threw bowls and ran, in short, the chaos was incomparable, and Yuan Shao did not dare to come out to command and stop the chaos, because the shells kept falling, and they did not dare to make any action at all.

Shot out the cannonballs he brought, Liu Yi clapped his hands and ordered a retreat, it was quite cool today, and I happened to bring Erin from Hanyang at night, and I was having a good time with her when I went back.

Yuan Shao was furious by the shelling, and he decided to attack Yangyi Pass tomorrow with secret equipment to restrain the flint.

Rest for the night, early the next morning, Yuan Shao and they came to attack the city, and they were fully prepared for this siege, and they would definitely be able to prevent Liu Yi and their fire stones.

"Rumble!" Yuan Shao's war drums sounded on their side, this time Yuan Shao used all the iron shields, a total of 1,000 yuan, this time he made the iron shield, if he didn't capture Yangyi Pass this time, then he could only vomit blood.

"It's coming! Artillery ready! Let all of these tricks die to death! Liu Yi personally controlled a cannon, then adjusted the height and loaded the shells.

"Boom!" Liu Yi was the first to fire, and then thousands of cannons fired.

Yuan Shao, who was in the distance, saw that the cannon on the tower of the city had opened fire, and hurriedly ordered the drummer to beat the defensive signal drum.

Everyone heard the defense drum and hurriedly raised a super net of ten miles, this time Yuan Shao thought about it, since it was a fire stone, then he would weave a super big iron net to defend, but this big iron net ......

"This ...... This...... Nima! There's no need to be like this! Liu Yi looked at the soldiers below who were blown up with iron nets to block shells, and he couldn't close his mouth in surprise, he had never seen such a trick to death! Iron mesh to block shells? This Nima!

"What's going on! Evacuate! "Seeing that the iron net defense is useless, Yuan Shao is anxious, this net has cost him a lot of money! Even when making this super iron net as fast as possible, hundreds of people died of exhaustion.

Seeing that Yuan Shao was about to retreat, Liu Yi would certainly not let them go, and ordered the artillery to keep bombarding until they ran out of the range of the artillery attack.

Coming to the city tower, Liu Yi sat on the yellow hussar and prepared at the gate of the city with 150,000 heavenly wolf horses, as long as the cannon stopped, they would go out and kill a good one, this time not to beat Yuan Shao this guy to a big injury, he Liu Yi is not a person!

The sound of the cannon stopped for a long time, and more than 20,000 corpses were left outside Yangyi Pass, including the iron shield and super iron net that Yuan Shao had made with his blood.

"Let's go! Remember to see one and kill one! Forget it if you surrender! Liu Yi picked up the gun and warned the 150,000 people behind.

"Ryo!" The city gate of Yangyi Pass, which had not been opened for a long time, opened, and Liu Yi chased after the defeated soldiers with 150,000 heavenly wolf cavalry.

The speed of the cavalry was very fast, and Liu Yi and the others caught up with the retreating coalition troops in a while. This time, the coalition army dispatched 200,000 people, and the retreat was very slow, and the 150,000 heavenly wolf riders under the leadership of Liu Yi directly rushed into the retreating team of 200,000 people and opened fire.

"Those who surrender will not be killed!" Liu Yi shouted while shooting, his shout made tens of thousands of people drop their weapons and surrender, Liu Yi's army is too strong, surrendering as soon as possible is the wisest choice.

Although tens of thousands of the 200,000 people surrendered, most of them still chose not to surrender, and those who surrendered were alone, and those who did not surrender were all at home in the Central Plains, and they still had families.

Liu Yi didn't know the hardships of those who didn't surrender, he only knew that those who didn't surrender were all diehards, and all of them were killed, and no one was left.

chased Yuan Shao's coalition army far away and killed more than 80,000 people, Liu Yi and they were not chasing, they had killed enough, there was no need to chase anymore.

Returning to Yangyi Pass with the troops, Liu Yi asked Guan Yu to take them down, and then came to the city wall to watch Yuan Shao's movements.

At this time, Yuan Shao was much older, the loss was his greatest, the money used by the iron shield and iron net basically used up his family property, and he also died the most, although this time it was a coalition army, he brought the most people, there were 100,000, several attacks made him 100,000 people become 40,000, if it weren't for him Jizhou and 150,000 people, I'm afraid Liu Bei and others would have to fight his idea, and this time his biggest loss was that Yan Liangwen Chou let him give his life in vain.

pulled out the camp and said something to Liu Bei, Yuan Shao is ready to return to Jizhou, this time he is seriously injured, and it is estimated that he will not be able to return to his original strength without a few years of recovery.

Yuan Shao and they were ready to retreat, Dong Zhuo, who attacked Xiping Pass, they also retreated, they couldn't attack it at all, there was still an unfinished gap in Yangyi Pass, Xiping Pass was simply monolithic, they couldn't be defeated at all, and they lost tens of thousands of people in vain.

This time, the coalition army attacked Xiliang and ended in a disastrous defeat, and every prince who came here suffered huge losses, and some even collapsed, and were wiped out by other princes after returning to the Central Plains, such as Ding Yuan.

The retreat of the coalition forces ended with a battle to the death.
