The siege battle was undoubtedly very painful for the Sui army.

An army of millions, which can go to the city and climb to the top of the city, and directly attack the city, will always be a small part, and more than half of the army will be idle.

Moreover, the Goguryeo defenders in the city were not quite numerous.

In addition, the Goguryeo people were also very well prepared.

Needless to say, the people on the north bank of the Goguryeo River (Yalu River) have almost all moved into the fortress.

As an important military town in Liaodong, Liaodong City has the most capable generals, the most elite soldiers, and the most abundant grain and grass in Goguryeo.

Although it has suffered repeated defeats and the defenders of Liaodong City have suffered heavy losses, it is still more than enough to defend Liaodong Jiancheng in terms of troops.

In terms of tactics and weaponry, they are far from the Sui army.

But in the brave and tough, it is not slightly worse than the Sui army.

If it weren't for the Central Plains Empire, it would have come to the peak of martial arts, otherwise, Goguryeo at this time could be compared with the later Jurchens and Khitans.

In this way, the offensive and defensive battles of Liaodong City are not to be said to be tragic.

The soldiers gathered like ants, up and down the city, and the shouts of killing were deafening.

Arrows fluttered in the sky like locusts, and swords and spears glittered in the sun.

The dense Sui army soldiers braved the rain of arrows, filled the trenches, erected cloud ladders, and then climbed up.

They were greeted by falling arrows, stones, and boiling oil.

No matter how noisy the battlefield is, it is difficult to hide the screams of the wounded and the cries of pain.

No matter how many colors there are, they can't hide the dazzling red that keeps flowing.

Three days, three days of non-stop reciprocation and monotony.

The Sui army, together with the Goguryeo defenders, turned the city of Liaodong into a place like a flesh mill.

The city walls became mottled, and the corpses on the city were accumulated, and the blood flowed down the battlements, merging with the blood of the Sui soldiers stained on the city walls.

It makes the tall Liaodong city walls look terrifying and intimidating.

The earth beneath the castle was soft and muddy, stained with a faint dark red.

The strange-shaped corpses formed a circle around Liaodong City like a fence, and the Futu Hell was nothing more than that.

Every evening, a raging fire would rise inside and outside the city, where the Sui army and Goguryeo defenders were burning corpses.

Soon the air began to get cloudy.

A burning smell that affects people's appetite every day, wafting in the air and lingering.

And since the beginning of the war, the Sui army has also suffered the heaviest casualties.

Every day in the siege battle, thousands of Sui soldiers will be buried under the city of Liaodong.

Perhaps, this sounds like a slight damage to an army of millions.

However, you must know that this is the beginning of the siege battle, and it is far from the end.

After Li Po saw the siege battle in the first three days, he also felt a little chill behind his back, such a primitive and bloody siege battle, if he didn't see it with his own eyes, it was almost unimaginable.

No matter how brave a warrior is, in such an offensive and defensive battle, he will not have too many opportunities to show his bravery, and whether he can survive depends on his luck.

Although, Li Po felt that his luck had always been good.

But he definitely didn't want to participate in such a war and leave his fate to God to decide.

However, Li Po watched it for a few more days before he slowly understood.

The first three days of the battle were just a temptation of the Sui army, and siege warfare, especially the attack on a fortified city like Liaodong City, required not courage, but patience, and a cold heart that was different from ordinary people.

Human life, in the eyes of wise generals, has always been just a number, when a general of a large army, when he becomes soft-hearted, he is not worthy of leading a large army to fight on the battlefield.

That would put himself, and his men, at risk, for a great army never tolerates much mercy and mercy, and that is a sign of weakness, and your enemies will soon find out about it and take advantage of it.

Don't be lucky, Li Po understood this truth before, but this time, he was even more impressed.

The generals of the Sui army once again made a statement to the emperor that they wanted to divide their troops.

Because of a few days of temptation, the defense of Liaodong City made them feel tricky.

Although, all kinds of siege equipment are gradually completed, and when the battle is renewed, the situation will be very different.

But it was too wasteful for a million-strong army to be stationed under a fortified city.

Even if you can't send troops directly into the hinterland of Goguryeo to attack the capital of Goguryeo, the land of Liaodong is not the next Liaodong city, and there are still a few big Goguryeo cities.

Moreover, after a few days of fighting, the generals also saw it.

Goguryeo Tun is heavily armed in Liaodong City, so, in other places, will there be an empty army?

But their proposal was rejected again by the emperor, and Emperor Yang Guang of Sui wanted a complete crush, not an opportunistic victory.

So, in the next two days, the siege battle suddenly became fierce.

The previous one was just an appetizer, and even if it was a bloody appetizer, it was an appetizer.

At this point, it can be regarded as a real siege.

The chariot, which was as tall as the Liaodong city wall, finally appeared on the battlefield, and the car that hit the city gate also became thicker and more solid.

The soldiers of the Sui army who ascended the city also changed from Hebei and Shandong to the real Sui army.

In the past two days, it has been several times in the city.

Although they were all driven down, it also symbolized that the destruction of the city was only between morning and evening.

And the battle in these two days was much more cruel than before, and the soldiers of the Sui army who fought to the death and did not retreat abounded, showing the terrifying attack power of the Sui army.

The casualties of the Goguryeo people increased suddenly, and the pressure also increased several times at once, because the Sui army had already found the weak point of Liaodong City.

Seven times in the city, five times in the north city.

At this time, the Sui generals had more choices, whether it was to storm the northern city wall, or to use it as bait to attract the attention of the Goguryeo defenders and capture another city wall, it was a very good choice.

Because of the Sui army, the most important thing is people.

However, after two days, although the generals of the Sui army still had good patience, the faces of the generals in the army were extremely gloomy.

Because in the past two days, the casualties under the city of Liaodong are the essence of the Sui army.

If it is a field battle, the casualties of these two days are enough to fight each other with a powerful Turkic tribe in the front, without losing any advantage.

But such efforts were not appreciated and comforted by the emperor, but were reprimanded by the emperor for incompetence.
