Three days later, Cao Cao and Yuan Shao's 500,000 coalition troops gathered here, this time the coalition army was much stronger than the last time Yuan Shao stopped, the coalition army included Cao Cao's elite cavalry, tiger and leopard cavalry 100,000 and Yuan Shao's financial resources to train the two states of Storm Archer Battalion 50,000.

"Brother Mengde! Come! With this glass of wine, let's go on the expedition! Yuan Shao stood on the high platform of the 500,000-strong army and raised his glass.

"Good! Primordial! May we capture Xiliang and kill Liu Yi in one fell swoop! Cao Cao raised his glass and toasted to Yuan Shao, and the two of them drank it all.

"Wen Yuan will go down and lead the army to set off!" Cao Cao gave an order to Zhang Liao beside him, and then Yuan Shao also gave an order to Zhang He next to him.

The army was reorganized, the 500,000-strong army was mobilized, and the biggest battle of the year was about to begin.

Hanyang, outside Hanyang City, at this time, Liu Yi was also rectifying the army, pulling out Yangyi Pass and Xiping Pass, Cao Cao, and the news of their departure Liu Yi received it as soon as possible, he must annihilate Cao Yuan's 500,000 allied troops under Yangyi Pass and Xiping Pass this time.

"All of them! Ready to go! Liu Yi was on the tank with a megaphone and shuttling between the legions.

"The Sky Wolf Rider has assembled and set off!" Ma Chao shouted loudly and set off first with 100,000 heavenly wolf horses.

"The infantry corps is assembled and departed!" Guan Yu shouted and followed behind the Sky Wolf Cavalry with 100,000 infantry.

Seeing that the two major armies were leaving, Liu Yi also set off with a hundred tanks and fifty armored vehicles, pulling the latest weapons of the arsenal behind the tanks and armored vehicles.

On the way to Cao Cao and Yuan Shao, Liu Yi and they had already arrived at Yangyi Pass and Xiping Pass, Xiping Pass did not need to do too much defense, there was still a long way to enter the interior of Xiliang, and even if they entered Xiping Pass, behind Xiping Pass was a deep canyon, Cao Cao and Yuan Shao would not be stupid enough to attack Xiping Pass with all their might, and then enter the canyon behind Xiping Pass for Liu Yi to ambush them.

Yangyi Pass is a difficult to defend and easy to attack level, so Liu Yi and they have to be prepared, although there are guns and cannons, they are not afraid of Cao Cao and Yuan Shao's army with cold weapons in their hands to attack the city, but everything will change, so they still have to be fully prepared.

First set up cannons on the high ground near Yangyi Pass, and then go to Cao Cao and Yuan Shao to plant thousands of mines on their way, and make all this arrangements, just waiting for Cao Cao and Yuan Shao to send them to death.

Liu Yi and their defense was arranged, Cao Cao and Yuan Shao's mighty army of 500,000 was still in Yongzhou, Yongzhou had been pocketed by Cao Cao earlier, so Cao Cao and their march was unimpeded, a week later, Cao Cao and Yuan Shao arrived at Yangyi Pass a hundred miles away and camped, for Xiping Pass, Cao Cao They did not send a single soldier, Xiping Pass is an easy place to defend and difficult to attack, and it is of little strategic significance, so they don't need to waste time and energy to attack Xiping Pass, As long as the Yangyi Pass is broken, a small Xiping Pass is definitely not a problem.

In the evening, Cao Cao and Yuan Shao's allied forces were setting up stoves and preparing to make a fire for cooking, while Liu Yi was holding a telescope with Zhen Mi and a few soldiers on a small high slope five miles away to observe.

"Mi Mi! There will be a fireworks show later! Do you want to see it? Liu Yi whispered to the beautiful Zhen Mi who was wearing a special female soldier uniform next to her.

"Good! Hurry up! I want to see a fireworks show! Zhen Mi clapped her hands happily.

"Pass the order! The Tianhuo cannon shelled the camp of Cao Cao and Yuan Shao's coalition army for twenty rounds! Liu Yi said to the telegraph operator under the small high slope.

"Yes!" After the telegraph operator finished speaking, a telegram was sent to the artillery position, and as soon as the artillery position received the order, the Tianhuo cannon artillery quickly took position, and then adjusted the ten-meter-high barrel to aim at the direction of Cao Cao's and Yuan Shao's allied army camp, and the cannon firing range was much larger than that of M2, with a radius of two hundred miles.

"Bomb!" The flag commander raised the yellow flag in his hand, and the yellow flag raised a huge cannonball and stuffed it into the cannon boring of the skyfire cannon.

"Launch!" The flag commander lowered the yellow flag and raised the red flag, and as soon as the artillery pulled the strings, 150 cannons opened fire, and the huge recoil shook the artillery position into dust.

"Boom boom~" The powerful cannon shell fell into the camp of Cao Cao and Yuan Shao's coalition army, and the soldiers in the coalition camp were still surrounding and preparing to eat, and suddenly they were blown up by the shell.

"Hurry up and hide in the ditch you dug! Hurry! "The coalition battalion, from the captain to the centurion, mobilized to prevent the soldiers from entering the dug trench to avoid the shelling. After the lessons of the previous shelling, Yuan Shao has summed up a way to dodge, that is, dig a deep trench around the barracks, and the soldiers will hide in it, and the losses will be relatively small.

With the loss of several thousand soldiers, the entire coalition battalion went into the ditch to hide from the shelling.

"Mi Mi! Isn't it good-looking! Liu Yi looked at the coalition camp that was blown up everywhere and said to Zhen Mi next to him with a smile.

"It's not pretty! Not as good as Sister Erin said! Sister Erin says that the fireworks are in the sky and are colorful, and you see that the fireworks on the other side are nothing but stir up the dirt and ignite a fire! Zhen Mi pouted and looked at Liu Yi dissatisfied.

Looking at Zhen Mi, who was pouting, Liu Yi smiled and said fondly: "Mi Mi! The kind of fireworks you want to see don't have right now! When you return to Hanyang after this battle, I'll let Erin take you to see it, okay? ”

"Alright! Let's go back! It's not fun here! I'm going back to see the red-faced Uncle Guan playing with a big knife! Zhen Mi pulled Liu Yi down the small high slope.

"Mi Mi! Can you not call the second brother Uncle Guan! You're not my daughter! Calling the second brother to be Uncle Guan is not a lower grade and seniority? Liu Yi said a little speechlessly.

"I just want it, people can do what they want!" Zhen Mi stuck out her tongue mischievously at Liu Yi.

"You are someone's sister-in-law calling someone to be an uncle! This is simply ......" Liu Yi shook his head helplessly and took Zhen Mi to the tank and went back, while they were still shelling behind them.

At the end of the twenty rounds of shelling, the camp of the Cao Yuan coalition army was blown into a mess, and the tents and many things were blown to pieces.

"Primatim! Good thing you're prepared! Otherwise, the casualties will be big today! Damn Liu Yi, I'll give you a try on our Fire Meteor in the middle of the night today! Cao Cao said fiercely.

"This Liu Yi! Many of our soldiers have died at his hands! Revenge must be taken tonight! Yuan Shao on the side also said indignantly.

In the middle of the night, Cao Cao and his team carried 200 fire meteor slings out of the camp.

"Hurry! Hurry! Cao Cao rode on his horse and urged the soldiers behind him to transport the fire meteor catapult.

"Brother Mengde! You're too bulky, it's far inferior to Liu Yi's flint stone launcher! Yuan Shao looked at the soldiers behind him who were desperately pushing the stone thrower.

"I can't help it! The farther the launch is only to increase the weight ......"

"Bang! Bang! Bang......" "Ahhh......hhhhh

"What's going on!" Cao Cao controlled his startled horse and looked at the place where the soldiers in front of him were screaming.

"It is estimated that it is a kind of thing called a mine made by Liu Yi! Dong Zhuo told me before: This kind of thing can spew stones to kill people when buried underground! Yuan Shao explained to Cao Cao the screams ahead.

"What then?" Cao Cao said embarrassedly.

"Trample on it with human life! Until you step on it! Yuan Shao's tone became cold, and the soldiers next to him were all scared when they heard this.

"I'm afraid that's not right, right? If this can't be finished, won't countless people die? Cao Cao said as he looked at the soldiers around him who had begun to be timid.

"Is there any other way to do it?" Yuan Shao's tone was very calm but cold.

"Use the horses! A man's life is much more valuable than a horse's! "Although Cao Cao is ruthless, he will not let the soldiers die in vain.

"Use the horse to get the horse! Hurry up! Yuan Shao was a little impatient.

"Go lead the horses!" Cao Cao instructed one of his soldiers.

Soon thousands of horses came, and the soldiers, whipping their horses, neighed, and rushed forward to step on the mines.

"Bang bang...... "Thousands of mines were stepped on at the same time, and the poor horse was blown to pieces.

"Go and see!" Yuan Shao ordered dozens of soldiers to go up and take a look. Those dozens of soldiers, you look at me, I look at you, and finally you go up helplessly.

Dozens of soldiers cautiously walked to the mineed area, and they were lucky not to step on the mine that did not explode.

Seeing that the dozen or so soldiers passed smoothly, Cao Cao and Yuan Shao also began to pass through the minefield surrounded by hundreds of soldiers.

"Bang!" A soldier was unlucky enough to win the lottery and stepped on a landmine. The soldier was instantly blown to pieces, and his flesh flew everywhere, some of which were splashed on the faces of Cao Cao and Yuan Shao.

"!" Cao Cao stabilized the frightened horse again and scolded angrily.

"Brother Meng De told the soldiers to disperse, and then a few soldiers walked ahead of us," Yuan Shao said, controlling the frightened horse.

Cao Cao nodded in agreement with Yuan Shao's words.

ordered all the soldiers to disperse, and then several soldiers walked in front Cao Cao and Yuan Shao cautiously walked through the minefield, and a very small number of the scattered soldiers stepped on the mine. After making sure there was no danger, the Fire Meteor Catapult began to follow.

Slowly walked with the catapult for a long time, and finally arrived in front of Yangyi Pass, determined the position, and began to prepare for the stone.

"Liu Yi also let you taste the benefits and disadvantages of our fire meteor!" Yuan Shao looked at Yang Yiguan not far away and said fiercely.

"Stone-throwing! Let them taste our stakes! Cao Cao ordered the stone to be thrown. Hearing Cao Cao's order, two hundred fire meteor catapults began to throw stones.

"Bang bang ......"

Two hundred boulders were thrown at Yangyi Pass, and when the boulder was lifted into the air, flames suddenly appeared, and the firelight illuminated the wall of Yangyi Pass and smashed on the wall of Yangyi Pass poured concrete. The boulder smashed on the city wall of Yangyi Pass was smashed instantly, the city wall after the boulder impact did not cause a little impact on the city wall, because the boulder used by the fire meteor is coated with fire oil, which contains phosphorus, and when it is lifted into the air, it is rubbed and burned with air, and the boulder is also softened a lot when the phosphorus burns, so there is no harm at all when it hits the city wall built of concrete.

After a few more rounds, it still didn't work, which made Cao Cao and Yuan Shao very crazy, what the hell is going on, since it is useless to smash it on the wall of Yangyi Pass.

"Ancient times without knowledge of chemistry just can't do it! Their fire meteor show is over, it's time for our heavenly fire! Artillery ready! Give them a taste of the real technology! Liu Yi stood on the artillery position, jokingly watching Cao Cao and Yuan Shao, and their fire meteors smashed the city wall of Yangyi Pass.

"Skyfire cannon fire!" The flag commander raised the red flag that was fired, and one hundred and fifty cannons opened fire.

"Boom, boom, boom, boom......" The cannon shell fell on the fire meteor catapult, and soon Cao Cao and Yuan Shao were in chaos.

"Everybody, run, run! No more catapults! Yuan Shao had already run away the moment he saw the shelling landing, and at this time the others were already dozens of meters away.

Knowing the power of the cannonballs, everyone fought desperately, and the cannonballs followed them all the way without stopping.
