Today, Liu Siyuan almost let Li Rui be stoned to death.

He really didn't expect that Li Rui's army still had the kind of giant catapult of the Tang Army in his army.

For several days, when Li Rui was dealing with the slave army, he rarely even used strong crossbows and bows and arrows, and only when the Liu family headquarters attacked, these long-range weapons began to appear on the battlefield to suppress, so Liu Siyuan was careless.

Today, in order to encourage the army to attack, his Chinese army banner is too close to the dock fort.

The Tang Army's most powerful crossbow has a farthest range of only more than 300 steps and less than 400 steps, but if it really reaches this range, the strength is actually about the same, and it is difficult to cause too much damage. Liu Siyuan moved the banner of the Chinese army forward to a place more than 600 steps away from Wubao, thinking that he was already quite cautious.

But Li Rui has two giant catapults that have not been used.

In the past two days, he was smashed to death by those simple catapults built by Liu Siyuan, Li Rui gritted his teeth and did not use these two catapults to fight back.

Today finally gave him a chance.

Two large throwers were placed in the center of the fort, and at this distance, the opposing slings could not hit them from either direction. After all, the other party has a lot of catapults, and if they find out the location of their own catapults and shoot in a group, they may be able to touch the dead mouse by a blind cat.

After sacrificing a certain attack distance, Li Rui ensured the safety of the two catapults. The two catapults installed in the middle of the fort could still strike a distance of about seven or eight hundred paces outside the city, no matter which direction they attacked.

In fact, above this distance, he was enough to suppress Liu Siyuan's long-range bombing.

Several officers of the trebuchets climbed on the roof and repeated the measurements for a long time, and the two catapults, which had not squeaked until now, began their show for the first time.

Li Rui expects a lot from them.

Two stone bullets weighing hundreds of pounds smashed into the location of Liu Siyuan's Chinese army banner with a bang.

Wherever the stone bullet went, people turned on their backs. The catapult soldiers have been idle for the past few days, polishing the stone bullets to a round shape, but at this moment they are showing great power.

After the huge stone egg hit the ground, it bounced high again, and then the bones rolled on the ground, but whenever there was something to cushion it, or a human corpse, or an inconspicuous small stone, it would make him suddenly change direction, and the big guy of hundreds of pounds rolled and rotated under the huge kinetic energy, and if it was really rubbed next to it, it would either die or be injured.

The two stone bullets turned Liu Siyuan's Chinese army upside down and caused chaos.

His banner of the Chinese army fell for a time.

This made the soldiers in the fort thunderous with joy.

It also made the attackers lose their minds for a while, and then retreated like a tide.

However, to Li Rui's disappointment, his Chinese army banner was erected again, only this time, they retreated straight back to a thousand steps away. The retreating Liu army was restored soon after. This made Li Rui understand that Liu Siyuan was probably in danger and was not killed by his sudden attack.

It's a bit of a disappointment, but that's about it. This kind of blow itself is a stroke of luck, and the trebuchet is not a sharpshooter like Chen Changping. Two stone bullets disintegrated one of the opponent's attacks, and also caused great damage to the opponent, which was actually worth it.

Of course, such a thing can only happen once.

Next, the two large trebuchets began their show.

Stone projectiles flew up one after another, destroying the opponent's improvised trebuchets that were densely packed outside, one after another. This feeling of just beating the enemy and not being afraid of the enemy doing it made the soldiers in the fort very proud.

Due to the trebuchet attack of the opponent who had been scratching them for several days, it was now crushed.

What Li Rui didn't know was that Liu Siyuan was actually brushing shoulders with death today.

The moment the stone bullet was closest to him, it was actually only a few steps away, and it was still the time when the momentum was at its strongest. At that time, the stone bullet was removed from the air, and when it landed not far from the banner of the Chinese army, everyone's breath was almost stagnant, and several elite soldiers of the Liu Department who bore the brunt of the stone bomb did not even snort, and were turned into pieces of meat by the stone bullet, and then the stone bullet began to spin and bounce, rushing towards Liu Siyuan.

Even though there were already several dead soldiers standing in front of Liu Siyuan at that time, it was actually useless to block this thing with flesh and blood.

While everyone was screaming in amazement, the stone changed direction at the most critical moment. A protruding stone on the ground made the stone bullet jump, turned a corner and then flew away with them, and at that moment, Liu Siyuan could even see the engraved stripes on the stone bullet clearly.

Survived under the sickle of death, which also made Liu Siyuan furious.

The Chinese retreated to Lixu, and then the large forces began a fierce attack regardless of losses.

This time it was no longer just the slave army, and the Liu headquarters was mixed in and began to rush through the pass.

The pressure on the dock increased suddenly. Liu's soldiers and horses, every time they attacked, they attacked the city, but they were beaten back under the fierce counterattack of the right Xiaowei soldiers.

The casualties caused by Liu's several fierce attacks to Li Rui were already the sum of the past few days.

That is, after repeated fierce attacks to no avail, Liu Siyuan finally decided to use the secret passage built by Kan Yan.

Two of the three secret passages were destroyed, but Liu Siyuan was not angry but happy.

This can only show that there is another one that the other party has not discovered at all, not to mention that Kan Yan's practice of arranging this secret passage in an ordinary soldier's house is even more unimaginable.

Kan Yan, Liu Yan led five hundred elite troops to secretly sneak into this secret passage when the attack outside was most intense, and then attacked from the inside out, which would inevitably break through the dock fort.

Liu Siyuan's calculation was not wrong, if Li Rui hadn't discovered this secret passage.

Li Rui not only discovered this secret passage, but also insidiously dug a pit for the other party.

For Li Rui, this is simply too commonplace. From the meticulous work, he has always liked to plan and take the chestnut from the fire, because the results obtained in this way are often the smallest, but the rewards are the most abundant.

But Li Rui never thought that he would be able to capture such a big fish.

Of course Kan Yan doesn't count, he can only be regarded as Liu Siyuan's dog.

But Liu Yan is different.

He is Liu Siyuan's second son.

Kan Yan was blessed with more than a dozen soldiers to take it down, even if he was not lightly injured, but Kan Yan was worthy of being a murderer, and his combat effectiveness was extremely strong, until both legs were discounted, he was barely captured alive.

On the contrary, it was Liu Yan, who was easy to catch.

Liu Yan was pulled out of the collapsed bungalow.

When the accident suddenly happened, several loyal subordinates of the Liu family reacted very quickly and pulled Liu Yan back into the house, wanting to withdraw from the tunnel, but including this bungalow and the tunnel, they had already been manipulated by the Tang army, and the moment they retreated, the house collapsed, and the tunnel also collapsed.

Liu Yan was not stoned to death, and several loyal Liu subordinates protected him to the death. It was cheap Tang Jun and caught Liu Yan who was unscathed and just disgraced.

The blessing paid the price of two people killed in battle and more than a dozen wounded, and completely annihilated the elite of Liu Bu of nearly 500 people, plus captured the enemy generals Kan Yan and Liu Yan alive.

Li Rui once again repelled Liu Bu's frantic attack, but Liu Siyuan obviously had no intention of stopping, and with the rumbling sound of war drums, the reinvigorated Liu Bu pushed forward again.

At this time, he will never stop the attack.

The blessing pressed the captives up the city walls.

Looking at Kan Yan and the dozens of captives led by Liu Yan, Li Rui laughed happily.

"Come on, hang Liu Yan up for me, let Liu Siyuan see clearly, what are the feather arrows or something, just greet his son!"

The movement on the city wall finally attracted the attention of the attackers under the city. When they saw that it was Liu Siyuan's second son who was hanging above the city, the advancing team finally stopped.

A moment later, several horsemen rushed to a place less than a hundred paces below the city, as if to confirm Liu Yan's authenticity.

Kan Yan and dozens of other captives were pushed onto the city, and behind each of them, there was a Tang soldier with a horizontal knife in his hand.

"Liu Siyuan, I'll give you a surprise today, hahaha!" Li Rui laughed and waved his hand, dozens of horizontal knives were raised high, and they fell heavily, and dozens of heads left their necks and fell towards the city.

Several knights under the city seemed to be a little frightened, glanced at the human heads that fell from the city and the corpses that were pushed down casually, confirmed the identities of those people, and looked up at Liu Yan who was tied to the city head, and several people hurriedly beat their horses back.

Liu's large army, which was preparing to attack again, began to turn to retreat.

"Liu Siyuan looks really sorry for you!" Li Rui patted Liu Yan, who was tied up with five flowers beside him, and said happily: "You should be glad that your Lao Tzu loves you, otherwise, I don't mind slashing you on top of the city to sacrifice the flag." ”

"What do you think you can get out of this guy? Change Liu Siyuan's withdrawal of troops? Gu Han asked.

"That can't be!" Li Rui said: "But it's possible to change something else, and it's good to delay it for a few days!" Don't we need time right now? If Liu Siyuan eats beef like this every day and goes crazy, and attacks us frantically regardless of losses, although I am not afraid of them, the loss of soldiers will always make people feel distressed, and it would be best to kill fewer people. When General Liu launches it, Liu Siyuan is afraid that he will no longer have the heart to spend it with me, right? ”

"Are you so sure that General Liu will make a big fuss about this?" Gu Han asked with a smile.

"Of course."
