At this moment, a huge ship of 5,000 stones rumbled from the west, this is a large ship specially used for ramming in the Song Dynasty, the hull is extremely strong, and the bow is equipped with a triangular pig iron battering head, which can easily knock a thousand-stone warship into two sections.

What's more, this is a steam engine ship, with a huge paddle wheel mounted on the back, which does not require sailors to row, and itself has a specific and powerful forward momentum.

The ship suddenly sounded its whistle, and the huge whistle frightened the Liao soldiers on the shore to retreat, and Yelu Hongji yelled in a hurry, "Stop it!" ”

But no one could stop the ship's mad advance, and the soldiers standing on the pontoon bridge fled in both directions, only to hear 'Boom! With a loud bang, the ship smashed the wooden box and stake, knocking open a gap more than ten feet long.

Dozens of soldiers fell into the water one after another, but the big ship began to turn around again after less than a mile, and hit the pontoon bridge again from the east, and the pontoon bridge near the section of Jiangxinzhou was smashed into three pieces, and nearly 100 soldiers fell into the water.

After the third impact, the pontoon bridge that the Liao army spent a day and a night building was only the first section near the north bank, and the other pontoon bridges that were a mile long disappeared.

Yelu Hongji's face turned pale, and he gritted his teeth and said, "I don't believe that there is no way to take the Song army's warships?" ”

He said sharply: "Mobilize the whole people and build a dam for the barrage!" ”

This is the last and most effective means, build a stone dam in the middle of a few zhang wide opening, so that the river is not blocked, and finally as long as a few bridges are built on the gap, the Liao army on the opposite bank can come over, and even the Juma River is no longer an obstacle for the Liao army.

It's just that it takes time to build a dam, and it will take at least hundreds of thousands of people to be busy for a month to complete.

But in the eyes of the Son of Heaven of Liao, the people of the world are all ants, and he will never cherish the people's power at this time.

Yelu Hongji immediately issued an order to recruit 300,000 people in Nanjing Road, use 500,000 heads of animal power, and quarry stones in Hunling Mountain, 20 miles away, to build a dam on the Juma River.

..........

The siege of Yixian had entered the ninth day, and the Song army had always blocked the news of finding a water source, so that Yelu Kunping finally had enough to endure it on the eighth day and ordered a large army to storm the city.

In addition to dealing with the Khitan army, the Han army, the Bohai navy, and the Xi army all went into battle, and Yelu Kunping sent a thousand sword and axe men to supervise the battle behind.

The drums of war rumbled, the offensive of 30,000 troops was like a tide, the Song army once again sacrificed a giant wooden array, thousands of huge trees smashed overwhelmingly to the Liao soldiers, the Liao soldiers suffered heavy casualties, but had to continue to run wildly, after thousands of casualties, tens of thousands of Liao soldiers finally attacked the city, the arrows at the head of the city rained down, the siege soldiers continued to fall to the ground with arrows, but the base of the siege army was too large, thousands of casualties could not affect the army attack, a siege ladder mounted on the city, countless Liao troops climbed to the city head like ants.

'Woo-' a low horn sounded.

Five thousand Liao cavalry rushed towards the city, they stretched out their bows and arrows in the gallop, and the dense arrows shot towards the city, and these cavalry also continued to step on the thistle terrestris or fall into the horse pit, but it did not affect the strong offensive of the Liao army.

The soldiers who threw the giant trees were constantly hit by arrows, so that the giant wood array was suppressed, and as soon as the besieging soldiers loosened their heads, they immediately accelerated their attack, and some soldiers began to climb to the head of the city and fight fiercely with the Song soldiers at the head of the city.

Yang Wenguang saw that the soldiers under the city were so dense that he couldn't even see the color of the land, he knew that the time was ripe, and immediately ordered: "Prepare for iron fire and thunder!" ”

The Song army pushed fifty small trebuchets and quickly fixed them at the head of the city, ten soldiers pushed the winch, and there was an iron hook under the iron throwing bag, a rope hooked it, and the other end of the rope was buckled in the iron hook on the ground, at this time, as long as the rope was cut, the trebuchet would be projected.

Two soldiers put fifty or sixty pounds of iron fire thunder into the throwing pocket, one soldier unscrewed his hat and lit the fire rope with a fire fold, the fire rope burned rapidly, and when it reached the red scale mark, the fire chief shouted, "Let go"

The rope was cut, and the trebuchet violently threw the iron fire mine, the range was about 100 paces, and according to experience, if the launch rules were strictly followed, the iron fire mine would either explode overhead, or explode on the ground.

Fifty trebuchets were fired almost simultaneously, and fifty black iron balls were thrown out of the city, and when Jelu Kunping saw the iron balls, he closed his eyes in shock, and plugged his ears with his hands, and the weapon he feared most finally came again.

"Boom!" "Boom!" "Boom!"

A series of earth-shattering explosions sounded outside the city, except for the soldiers who fought fiercely with the enemy, the rest of the soldiers covered their ears and squatted on the ground, the earth trembled, the walls shook, and the screams of the enemy were drowned out.

The shock wave swung in all directions, and for a time the smoke was filled, and the black smoke covered the earth, and more than 100 siege ladders were all shaken down by the shock wave, and thousands of Liao troops on the siege ladders fell to the ground one after another, and many soldiers were seriously injured.

Yang Wenguang did not hesitate, and ordered again: "Shoot again!" ”

They brought a thousand Iron Fire Thunder this time, and only fifty were used at a time, which was enough for them to use.

Soon, the second round of iron fire thunder was thrown down the city, fifty iron fire thunder rolled into the dense crowd and exploded again, limbs flew sideways, broken meat splashed everywhere, thousands of Liao troops were killed or shocked to death, even if they did not die, thousands of quenched iron nails burst out after the explosion of iron fire and thunder into the body, which will also cause serious damage to the human body, making it lose its combat effectiveness at least and die at worst.

Immediately after the third round of iron fire and laser fire, the explosion deafened the ears, and there was no one standing under the city, and black smoke completely covered the battlefield.

The three rounds of iron fire and thunder explosions caused more than 10,000 casualties to the Liao army, plus the previous giant wooden array and arrows, more than half of the 30,000 Liao army casualties, completely frightened the Liao soldiers into a soul, got up and ran back desperately.

Yelu Kunping let out a long sigh, it seems that the Song army has not cut off the water source, and it has the big killer weapon of iron fire and thunder, even if the army is killed and wounded, it will not be able to capture Yi County, how can he explain to the Son of Heaven?

"I really can't capture Yi County, it seems that I can only ask the Son of Heaven for guilt!" Jelu Kunping gloomily addressed the crowd.

A general advised him: "General, today is actually about to attack the city, it is better to try to attack the city on three sides and disperse the army, the lethality of iron fire and thunder will not be so strong." ”

Another general also said: "There are only two sieges of the city, and there are still more than 30,000 people in the army, so I am afraid it will be difficult to explain to the Son of Heaven, and it is recommended to continue the siege." ”

Yelu Kunping's henchman Xiao Jiuzhong said in a low voice: "I carefully observed the Song Army's Iron Fire Thunder, and found that the first time was the most lethal, the second time was weakened, and the third time the number of casualties was the smallest, why there was this result, the main reason is that when the third explosion occurred, most of the soldiers were lying on the ground, does this mean that as long as they can lie down in time, they can effectively resist the attack of Iron Fire and Thunder." ”

Under the persuasion of the generals, Yelu Kunping was a little tempted, and it seemed that his siege deployment was a bit of a problem.

"Alright! Continue the siege tomorrow and try to siege the city on three sides! ”

That night, the camp was bright all night, and the craftsmen rushed to make siege ladders overnight, and by the time the day was about to dawn, 500 siege ladders were ready.

The next day, the Liao army camp once again beat the drums of war, except for 3,000 soldiers and wounded soldiers guarding the camp, the rest of the nearly 30,000 troops were all on the line, except for the north city, from the east, west and south three directions to launch a comprehensive and all-out attack on Yi County.

'Boom! Boom! Boom! The drums of war shook the sky.

Yelu Kunping waved his sword and shouted: "Capture Yi County, the first person to attack the head of the city will be rewarded with a thousand taels of gold, and the official will be promoted to three levels!" ”

"Kill!"

30,000 soldiers shouted and rushed towards the three city walls, like a turbulent wave, the offensive was like a tide, the 13,000 Song troops on the city head were waiting for a strict battle, tens of thousands of rolling logs were ready, and a more brutal battle began.
