The fire burned for half an hour, and the temperature of the flames was terrifyingly high under the help of the oil, and people within a radius of thirty or forty paces could not stand on the fire at all, let alone the Liao army at the head of the city.

The upper part of the wall was blackened by the flames, and the lower part was burned ochre, as if even the rammed earth was about to melt.

Someone said something behind Su Jin, which made Su Jin break out in a cold sweat, it was a veteran of the guard, he said: "This kind of firing method is like burning clay pots and porcelain at the kiln mouth of our hometown." ”

Su Jin's waterfall sweat, if the city wall was not burned, but burned more solidly, it would be the biggest joke of this era, it is estimated that it will go down in history and be known as the first fool in the world.

After the flame was extinguished, Su Jin immediately ordered someone to take water and spray it on the city wall, and the burning red city wall was hit by ice water, and suddenly a white steam rose, like thousands of poisonous tongues spitting out letters and sneering, and the water vapor enveloped a large area, and the Liao army on the head of the city looked at all this dumbfounded, and really didn't understand what trick the Song army was playing, one would heat the city wall, and the other would quench the city wall.

The steam gradually dissipated, the city wall had been completely cooled, everyone stared at the city wall, the Liao army wanted to know what tricks the Song army played, and the Song army also wanted to know if Su Dashuai had been busy for a long time and could have an effect at the cost of paying hundreds of brothers.

The lower part of the small section of the city wall, which everyone was looking for, blinked their eyes, for fear of missing something, but nothing happened there, the city wall was still the same city wall, not moving at all, and there was no situation that Su Jin said would collapse.

The Liao army at the head of the city burst into laughter, and Yelu Kanrong laughed the loudest, laughing wildly at the head of the city, pointing at the Song army under the city and shouting: "The stupidest thing in the world is probably your group of Song pigs, in the cold, risking your life to burn the fire to the Lao Tzu, right?" Hahaha. ”

The soldiers of the Liao army also laughed wildly one by one, and all kinds of ridicule and sarcasm were denser than the arrows they shot, and they floated over with their heads and faces.

The soldiers of the Song army on the other side of the moat were speechless, and the soldiers risked their lives to carry firewood and oil, thinking that it would have a miraculous effect, but unexpectedly this was a joke, Su Dashuai was really whimsical, and it was impossible to think about it.

Su Jin's face was gloomy, he didn't know why this was happening, according to the principle, there should be no mistake, the walls of Seoul are not so strong, even if they can't burn down the entire section of the city wall, at least one layer can be shed, how can there be no movement.

"Dashuai...... Let's think of another way, there are inevitably mistakes, people are not sages. Jingtai comforted.

"Mahan, bring a bow and arrows." Su Jin said coldly.

Ma Han hurriedly took off the bow and arrow on his back and handed it to Su Jin's hand, Su Jin slowly took an iron-headed arrow, put it on the bowstring, and used all his strength to pull the iron bow apart.

Everyone said in their hearts: "The handsome man is confused, the city wall does not collapse, the handsome child has a temper, he has to shoot the city wall with an arrow to relieve his anger......"

I saw that the arrow struck the city wall with a whizz, nailed to the city wall and shook continuously, and then there was a rattling sound from the place where the city wall was on fire, although the sound was not loud, but it was clearly audible; Looking at the wall of the city wall, a crack visible to the naked eye slowly spread out at the place where the arrow hit, like a spider web, gradually spreading into multiple branches, before everyone's eyes fell on the snow, the loud sound suddenly penetrated the eardrums, and the lower part of the city wall within dozens of steps collapsed like a mountain collapse, stirring up dust in the sky.

"This ......," Jereukon Rong was stunned.

"Oh!!" The soldiers of the Song army thundered with joy.

The dust settled, the smoke and dust dispersed, and the city wall did not collapse, but the lower part of the city wall had been sunken in, forming a huge cave four or five feet deep, fortunately, the city wall was as thick as a zhang, otherwise it would have collapsed directly to form a doorway; At the junction of the old and new walls, a huge crack is extremely exaggerated, extending up to the top of the wall, although it is not broken, but it also looks crumbling.

Su Jin put down his bow and arrows and let out a long breath, a cold sweat broke out on his forehead, and he waved his hand: "Continue the second round of fire, this time pile the firewood in the depression and light the fire, as the Liao dog said, let's add another fire to his warm kang." ”

The Song soldiers shouted a promise, and as soon as they saw that this method was so effective, the soldiers were immediately full of energy, and everyone put on their shields and helmets, and rushed to the other side of the river with firewood and oil barrels; Yelu Kanrong recovered and shouted, "Don't fucking shoot arrows yet, stop the Song people from burning the city wall." ”

The soldiers of the Liao army reacted and immediately launched a dense fire, Yelu Kanrong hurried down the city to the imperial city to report the news, the Song army's method of burning the city was effective, only two more rounds of burning were needed, and the city wall was about to be penetrated, and the Han city would be broken at that time; Seeing this, the bow and arrow could not stop the Song army from frantically carrying fire oil and firewood, and he needed to transfer a crossbow cart to smash the ice on the river in order to stop the Song army's attempt.

The defense of the Liao people is focused on the imperial city, bed crossbows and other large defensive equipment are deployed on the imperial city wall, for the Han people live in Hancheng, not to mention the bed crossbow, even the war building is not allowed to build, at this moment they finally tasted the bitter fruit of crying, when Yelu Kanrong with five thousand reinforcements pushed more than a dozen bed crossbows to the southeast of Hancheng, the city wall has been burned down again, this time more fell off, the lower part of the outer side of the city wall has formed a huge pit as deep as a zhang, the cracks in the wall have been dense and are about to collapse.

Just as everyone was carrying the bed crossbow to the city, the city exploded, and the soldiers scattered in a pot of porridge at the city head and ran towards the city walls on both sides, and a lieutenant ran down the city with a sweat on his head, shouting: "Deputy Privy Minister, withdraw quickly." ”

Yelu Kanrong slapped his head and scolded: "The city wall is not broken, and you don't go to defend the city for Lao Tzu, if you dare to escape, Lao Tzu will kill you." ”

The deputy general said with a sad face: "My lord, I can't hold it, look at the root of the city wall, you listen." ”

Yelu Kanrong turned his head to look, but saw a rumbling sound from the inner wall of the corresponding fire place, Yelu Kanrong understood that the Song people did not burn the city wall for the third time, but carried the log to hit the last thin layer, needless to say, the last thin two or three feet could not resist the bombardment of the log at all, and the city wall really couldn't hold it.

More than 500 Song troops carried more than 30 logs across the river, the rain of arrows on the head of the city took the lives of more than 200 people, and the remaining more than 200 people successfully drilled into the collapsed tunnel, the Liao army could only sigh with admiration, the hungry man met the hungry widow, the frequency and strength of the impact were difficult to describe in words, the rumbling sound made the Liao army standing on the city wall terrified, they found that the cracks in the old and new walls had spread to the top of the city wall, and immediately chose to scatter and flee.

Their choice was wise, at the moment when a dozen depressions at the bottom were pierced, the heavy top crushed the weak lower part, and the entire city wall slowly fell like an iceberg collapsing like a sea, and more than 200 Song troops had no time to escape, and they were all crushed under the rubble.

The city wall of the north city finally collapsed, and a gap of twenty zhang wide appeared in front of the Song army.

Su Jin pulled out his waist knife and shouted: "Attack!" ”

The Song army, which had already lined up and prepared, rushed to the gap, and after thousands of people rushed into the gap, the ice bridge was finally overwhelmed and broken, but this was not enough to affect the entire battle situation, the defenders in Seoul had all withdrawn to the imperial city, and there was no decent resistance in the city at all, and the Song army was able to calmly build a simple pontoon bridge for the follow-up soldiers and horses to enter Seoul.

In half a day, it only took half a day's effort, at the cost of 3,000 lives and 4,000 barrels of oil, Seoul fell into the hands of Su Jin.

Su Jin immediately ordered the gap to be blocked, and thousands of bags of mud were re-plugged with bags, because Yelu Chongyuan's army would appear outside the city at any time, and Su Jin didn't want him to be able to attack the city at no cost.

The officials and big families in Hancheng have already fled into the imperial city, and the rest are more than 200,000 ordinary people, they are all Han people, and their status is also the lowest, and most of them are oppressed by the Khitans on weekdays, but they are all natives of Liao, and they don't have much good impression of the Song State.

In the afternoon of the same day, the Song army forcibly collected tens of thousands of sets of winter clothes, and at the same time forcibly collected grain, forage, firewood and other military supplies, and more than 80,000 people trekked in the cold for more than 20 days, camped in the ice and snow for several days, and finally had a real chance to rest for the first time.
