The siege is also divided into the local tyrant siege method and the poor siege method!

Like the previous Yellow Turban Army, the ants were attached to the siege of the city, relying on human lives. Not to mention the inefficiency, the casualties will be several times or even ten times that of the defending side!

Those with a bit of technical content use the excavation siege method, which is very cost-effective for forces that do not have strong siege equipment. However, correspondingly, the technical level required is also very high.

Digging tunnels is not as simple as imagined, without mastering the relevant professional skills, there is a high probability that you will encounter a landslide and then be buried in the ground, or dig out the water to drown yourself directly.

And the powerful and well-equipped Pingzhou Army adopts another way of playing - forcibly smashing!

Five hundred ordinary catapults, two hundred torch stone carts, and two thousand improved large bed crossbows bombarded the city walls of the country for three days!

Tens of thousands of ordinary stones were thrown into it, tens of thousands of improved burst torch stones were used, and hundreds of thousands of large crossbow arrows were shot.

Although there are also defensive facilities such as catapults on the walls of domestic cities, the equipment making process of Goguryeo is obviously several grades inferior to that of the Han Dynasty, not to mention the Pingzhou army, which has been improved by the public losers.

As long as Goguryeo's defenses dared to show their heads, they were immediately attacked by the Pyeongju army. After two days, almost all the large-scale defense equipment of Goguryeo was abandoned, and only the arrow tower and other facilities were available. However, so far, the Pingzhou army has not sent troops to attack the city at all, and has been hanging with long-range weapons outside the range of the arrow tower.

To put it bluntly, it is to rely on national strength and technological superiority to beat the Goguryeo side!

In the past three days, the walls of the inner city have long been riddled with holes. Although Gao Yanyou forced the craftsmen to brave the attack of the Pingzhou army to repair the city wall, the specific effect was not good.

"Dashuai, if you continue to fight like this for another ten days, the walls of the domestic city will definitely collapse completely. Without the city wall to rely on, the domestic city defenders are vulnerable! ”

Liu Hu, who came with Liu Yi to investigate the battle situation, said excitedly.

"If you continue to fight like this, you must kill me!" Because there were no outsiders on his side, Liu Yi spoke more casually, and looked at the excited Liu Hu angrily, rolled his eyes, and said.

"The equipment made by the public loser is easy to use, but it is really expensive!" Liu Yi pinched his teeth and said.

"In three days, simply calculating the cost of siege, we have already smashed out five million gold. Bursting torch stones, city-breaking crossbow arrows, this is all money, and the damaged siege equipment is even more distressing. Counting the various expenses of the army, we have spent an average of more than 2.5 million gold per day in the past three days, and if we count the left and right armies of Ziyi and Junyi, the Japanese army has spent more than 3 million gold! ”

Liu Yi gave Liu Hu a series of numbers with a painful face.

"Shhh...... So horrible! ”

Liu Hu immediately gasped when he heard this, according to the original plan, under normal circumstances, the annual military expenditure of the Pingzhou Army was 120 million gold. In the event of war, etc., additional funds will be disbursed.

In a few days, one-tenth of a year's military spending under normal circumstances was used. Thinking of this, Liu Hu looked at the crossbow arrows and torch stones shot out as if he was looking at gold!

"Marshal, then, why did you refuse our request to take advantage of the situation to send troops to attack?" Liu Hu asked with some puzzlement.

In the past, if you sent soldiers to take advantage of the situation to attack, even if you can't really open the walls of the domestic city, the results will definitely be greater than now!

At first, Liu Hu thought that this was done to reduce casualties, but no one could afford such a terrible price, and it would be impossible to explain it by reducing casualties.

"Silly boy, you think this was my idea? is such an extravagant and wasteful dissipation, even if you win and go back, you can't explain it! Such an attack was the result of Viet Vou's personal order! ”

"Huh? Why? Liu Hu looked at Liu Yi puzzled.

"For testing!"

"Testing?"

"That's right, for the test! In fact, a comprehensive and complete assessment of the combat strength of the Pingzhou Army, and then checking and filling in the gaps, is one of the main goals of this campaign! ”

"Since the beginning of the Vietnamese army, although the attack is invincible, our Pingzhou army's combat experience is mainly concentrated in field battles, and the experience of large-scale cavalry combat is particularly rich, but it seriously lacks experience in attacking large and even giant cities. The last attack on Liucheng was mainly to take advantage of the surprise attack and night battle. But this kind of cheapness is not available every time, and one day we will have to attack the city with dignity! ”

Liu Hu suddenly realized and said: "I see, I said why did the marshal suddenly become so negative, it turns out that everything is to test the combat strength of the Pingzhou army!" ”

"You should have heard rumors that in a year's time, our Binh Chau army will participate in a major battle of unprecedented scale under the leadership of Yue Wu. I can tell you unequivocally that this rumor is true, and Viet Wu is currently making preparations.

At that time, there was no shortage of strong forces in our opponents, how to attack and defend the city, how to minimize losses when defeated, and how to fight in the face of an army that was obviously stronger than ours, these are all things that we need to think about and verify. The conquest of Goguryeo was just a simple warm-up game! ”

Liu Hu's blood boiled when he heard this, and he asked excitedly: "Big brother, can I participate in the big battle in a year?" ”

"It's called Dashuai!"

"I'm sorry, Marshal, will I be able to participate in the big battle in a year?"

"If you can be promoted to the top of the top before the battle, I will guarantee that you will participate in the war!"

"Yes!"

Liu Hu shouted, and quickly estimated in his heart how long it would take to be promoted to the top of the super-first-class. Then, Liu Hu sadly found it difficult to achieve this goal.

With a roll of his eyes, Liu Hu planned to go back and beg the Liu family, there must be a lot of high-grade pills in the Liu family's hands.

"Don't go to my sister, I'll tell my sister and ask her not to help you. Only by virtue of your own ability to advance to the top of the super-first-class does it count! ”

Liu Yi didn't know what Liu Hu was thinking, so he immediately spoke up.

"Huh?!"

"Ahh

"Oh!"

After night fell, Liu Yi personally set off secretly with the most elite two thousand hundred war phantom pawns, five thousand ghost ghost riders, and five thousand star longbows.

The exclusive special arms of each general in the Pingzhou Army belong to each general under their separate management in peacetime, but in wartime, only 10,000 per person is retained as a pro-guard army, and the rest must be distributed uniformly.

Because of the mountainous territory of Goguryeo, Zhang He's phantom pawns in a hundred battles have become the most popular type of troops.

Liu Yi took 10,000, Tai Shici took 10,000, and only 30,000 were left in the end to Zhang He's left army. Of course, Shang Ji also allocated a corresponding number of Star Glory Bows and Sun Riders for Zhang He.

Because it was from the mountains and forests, the ghost rider could only abandon the war horse and became an infantry soldier. Fortunately, the special troops are extremely adaptable, and without a war horse, they will immediately become excellent infantry.

Liu Yixu set out at eight o'clock in the evening, passed through the dense realm of mountains and forests found in Luoshu, and secretly arrived at the junction of the southeast city wall of the domestic city at the end of the time.

Because of the high intensity of the siege in the past few days, the defenders of the domestic city have suffered heavy casualties. In particular, the southern city wall, which was the point of fire for the assault, was even more in disarray.

As a last resort, Gao Yanyou transferred the defenders of the other three city walls to strengthen the garrison of the southern city wall.

And the other three walls only have the basic garrison force left, and the combat strength of the soldiers is quite weak!

"Let's go!"

Looking at the city wall that was close at hand, Liu Yi waved his hand and ordered in a low voice.

Soon, five thousand ghostly pawns wearing black leather armor, holding black long knives, and wearing black cloaks, whose figures could not be seen without looking closely, stepped forward.

Under the cover of night, the ghostly pawns rushed towards the city walls at great speed.

And Liu Yi took advantage of the cover of night to lead the rest of his subordinates to lurk in the dense forest, staring at the ghosts and ghosts in action.

"Starlight Longbow prepares, in case of an accident, immediately cover the retreat of the ghost pawns!"

After a few breaths, the ghost pawn had already rushed within a kilometer of the city wall, and then he saw that the figure that was not easy to detect was blurred for a while, completely blending into the night.

Until the ghost soldiers stepped into the base of the city wall, the defenders of the city did not notice it at all. Using its flying claws, the ghostly pawn is like a swift monkey that quickly climbs to the top of the city walls.

"Everyone, listen to my orders and go full speed!"

Seeing that the ghost soldiers began to climb the city wall, Liu Yi knew that he would definitely be exposed next. After all, the defenders are not stupid, and the invisibility of the ghosts and ghosts is not completely gone. It's close enough that you can still see some clues!

"Inform Xu Huang to immediately lead the army to attack from the southern city wall!"

"Boom!"

As soon as Liu Yi's words fell, Xu Huang, who had already made preparations, immediately ordered an attack. The siege equipment such as catapults, which had been resting for a long time, were once again powerful, and the roar of the bursting torch carts was heard.

"What's going on?"

The Goguryeo defenders were in a panic, but all eyes were focused on the southern wall, as did the other three defenders.

"Huh?"

On the east city wall, a Goguryeo soldier suddenly sighed in confusion, something seemed to have come up just now?

Rubbing his eyes, he took two steps forward to investigate carefully, and suddenly found that a translucent phantom was raising a knife to slash at him.

"Enemy ...... Belch. ”

Before the word of the enemy attack could be shouted, I saw a stream of blood shoot out, and the head of the soldier flew up! At the same time, the ghost pawn in black clothes and black armor also revealed his body in place.

"Kill!"

With a burst of applause, more and more ghostly pawns appeared, raising their swords to kill the nearby defenders who were still confused.

"Quick, speed up!"

Seeing that the battle began at the head of the city, Liu Yi couldn't help but urge a few words, the wind was under his feet, and his body was like a bolt of lightning, quickly crossing the distance of two kilometers.

Grabbing the claws left behind by the ghostly pawns, several flew to the wall.

Just stood firm, but saw a general who looked like a military general rushing up from the staircase in a hurry, Liu Yi flew up and shouted: "Xingyuan slashed!" ”

The long knife slashed across the night sky, the stars flashed, and the generals and hundreds of Goguryeo soldiers under their command who were blocking the staircase were all killed, and they had no ability to resist!

Liu Yi in the night, even if Lu Bu comes, he is not afraid!
