'Bang, poof' Jin Army's salvo is empty, and the stone bullet rushes up a column of water in the river, but the blind cat also encounters a dead mouse, and the tall Shenwei as the main target is hit by two bullets, after all, the wooden plank is not as strong as rammed earth and city bricks, and the bow and top deck are smashed out of two basin-sized holes, which startled everyone, fortunately, the warships are docked at the bow of the ship against the opposite bank, with a narrow bomb surface, if it is horizontal on the river, leave the side to the enemy, I don't know if the road can improve the hit rate of the Jin Army.

"Order all ships to evacuate to the lower reaches of the river, and after the flagship is broken, open fire!" Zhai Cheng, who was sitting in the flagship, only frowned, wiped the water droplets splashed on his face, and said in a deep voice. He knew that the flagship was too big and difficult to maneuver, and if he went first, it would definitely block the channel and cause chaos, so he decided to use the flagship to attract the enemy's catapults and make the other warships move, and the flagship was more resistant to strikes, even if it was smashed below the waterline, the design of multiple watertight cabins could ensure that he would not sink in a short time.

After receiving the order, the battleships docked in the river raised their sails and anchored one after another, and turned their rudders in turn to sail downstream, although they could not fire with their gunwales at this time, but did not affect the main guns in the bow of the ship. The main guns are equipped with large-caliber mortar guns, which are slower to fire, but they are extremely powerful, and it is difficult to hit the target when moving, but they can also play a role in deterrence and disruption.

For a time, stone bullets and iron bullets flew and shuttled in the sky, and the sound of the golden soldiers' trumpets pulling trebuchets and the roar of artillery fire echoed outside the city, and the most powerful weapons in cold weapons and sharp weapons in hot weapons clashed. Both sides fired deadly projectiles at each other as fast as they could, killing them.

"Starboard gun salvo!" The battleship Courage at the head of the team was the first to correct the hull, and the captain Peng Xiu couldn't wait to give the order to shoot. More than 40 guns were loaded with flowering shells, which exploded violently after landing. A barrage of fifty paces wide was formed, though it failed to destroy the catapult. But the soldiers who operated the artillery were turned on their backs and lay on the ground by the bombers.

"With a thunderbolt!" Wushu, who was watching from afar outside the battlefield, waved his hand and ordered, and a team of substitutes quickly stepped forward to replace the dead and wounded gunners.

Wushu is also a person who is good at learning and summarizing lessons, in the confrontation with the Song army, he understood that the Song army's firearms are sharp, but they can't point where to fight, and they also rely on dense firepower to cover and kill the opponent, so the lethality to the group target is the greatest, so he used an evacuation formation when arranging the position this time, and did not concentrate the stone throwers together. Instead, it adopts a linear irregular arrangement, which reduces the hit rate of the artillery, and also avoids being wiped out, even if one or two are lost, they can still continue to shoot.

In fact, the thunderbolts used by the Jin army were still learned from the Song Dynasty, which were filled with flammable materials such as saltpeter and sulfur, dipped in grease on the outside, and some biochemical poisons such as croton and wolf dung were also put on the high-end ones. The spherical shape rolls with a fire wherever it rolls, and the grease is caught on fire, and the toxic smoke emitted will also make people lose their combat effectiveness and even die.

"Prepare fire extinguishing tools. Pay attention to the protection of key parts! "Although certain fire prevention measures have been taken, the wooden battleship is most afraid of fire, and the planks of tung oil are brushed in order to prevent corrosion. The sails made of linen and the ammunition used to store gunpowder were all things that were caught in fire. Seeing the flying fireball, everyone was nervous. Fire warnings were issued on all ships.

"Load the chain bullet and aim it at the enemy trebuchet!" Zhai Cheng ordered, and the Song warships that were in a state of passive attack gradually dispersed, and the thick smoke from the continuous shooting also obscured the position of the battleships, and the ships that had adjusted their combat positions also began to counterattack.

Chain shells are mainly used to limit the action of enemy ships, it is to use chains to connect two small shells smaller than the bore caliber together, after firing, one shell will drag the other shell centrifugal and fly out, so it will pull a big hole in the sail, or tear the rigging, with good luck, it can even tear off the mast and paralyze the enemy ship.

Zhai Cheng found that his naval guns could kill and injure enemy soldiers by firing shells, but it was difficult to destroy trebuchets so that they could change people to continue their work. Unlike solid bullets, which can hit directly on shaking water, they can turn point kills into face kills, dragging the trebuchet down or even breaking it by the huge force generated by rotation.

As the battle unfolded, the weakness of the Jin army's trebuchets was gradually exposed, because the gun carriage was heavy and difficult to move, and it was very troublesome to change the direction of the projectile at any time. What's more troublesome is that the trebuchet relies on the pull of manpower to launch stone projectiles, and it is inevitable that the force used for each launch is uneven, and the distance is naturally different. As time increased, the physical exertion was serious, and the range became shorter and shorter, and it became difficult to hit the Song ship.

But at this time, the Song Navy gradually found a feeling, they no longer blindly scattered shooting, but the use of segmented shooting, according to the position of each ship to deal with the nearest trebuchet, even the gunwales on a battleship are also divided into different types of ammunition, to avoid the shortcomings of everyone aiming at one target, greatly improving the combat efficiency. The trebuchets of the Jin army were destroyed one after another, and the casualties were increasing, and finally they had to withdraw from this unfair artillery battle......

Looking at the messy battlefield, Wushu was a little depressed, in fact, this defeat was not a big loss for the Jin army, and most of the soldiers in Lasso were captured Goryeo coolies, but it was just a matter of taking some more trouble. The biggest loss was actually the impact on morale, and after a hard battle, they failed to sink or even severely damage an enemy ship, which made the army start to suspect that it was a wrong choice to stay.

But Wushu is a frustrated and courageous alternative, he didn't think of giving up at all, victory and defeat are a common thing in soldiers, not to mention that it is not the first time to fail, he decided to fight with the Song army, even if he can't beat them, he has to spend it with them, waiting for the arrival of the harsh winter, but the revenge of one arrow can not be avenged, he summoned the generals to find a way.

"Taishi, after the Song army that came to the aid this time captured the Datong River, it has been unwilling to go to war, and the last general thought that they came in a hurry, and the grain and grass baggage were very small, so they must be waiting for Goryeo to raise for it, if they sent an elite army to go deep into Kaijing to intercept and kill their baggage, burn their grain and grass, and when there is no food in the city, Xijing can not attack itself!" Wanfu Wan Yan Nie Er proposed.

"Well, this plan is good, you immediately select elite soldiers from your army to go to Kaijing to rob grain!" Wushu glanced at him and nodded.

"This ...... The last general had no boat to cross, and the Song army burned the pontoon bridge, and the battleships blocked all the ferries on the Datong River, and the last general ...... The end will not be able to cross the river! Wanyan Nie Er didn't expect a report from the present world, and the Taishi handed over the task to himself, blushing and stammering and replied.

"Hmph, if you can cross the river, can you still allow the Song people to be rampant? Now the priority is to think of ways to defeat the Southern Korean naval army! One of the people next to Wan Yan Nie Er snorted coldly, as if he was laughing at him for having a bad idea, and he would be able to cross the river and use him for being verbose.

"Yu Lie, what do you mean? Don't forget that you are also a defeated general of the Song army, let's see if the ground is flat under your feet! Wanyan Nie Er didn't dare to stare at Wushu, but he was not afraid of him, and when he heard his words, there was a sneer, and he turned his head and sneered.

"I have been defeated by the Song army, but I have never been defeated by you!" Wanyan Yulie was knocked off his horse and injured his leg in the siege battle to aid Yanjing, and he was disabled, but he didn't want people to say that he was lame, only that the ground was uneven, and now he was exposed by Nie Er.

"Hehe, who would be afraid of you cripple, let's divide it today!" Wan Yan Nie Er also pulled out the knife and shouted.

"Presumptuous, you dare to fight privately above the handsome hall, have you lived enough? Have the ability to go to the Southern Navy! Seeing that the two of them were not talking, the prison guard got up and reprimanded.

"The last general will not dare!" The two of them listened to the vulture on the handsome seat, and saw that the Taishi's face was pale, his eyes were murderous, and he hurriedly returned the knife into the sheath and bowed down to plead guilty.

"Thirty lashes for each of you!" Wushu said coldly.

"The Taishi is angry, and the last general will obey his orders!" The two hurriedly accepted the punishment, glared at each other indignantly and stepped aside, both with a look of 'you wait for me'.

"Taishi, there will be a plan in the end, I don't know if it is feasible!" A person who had been silent for a long time suddenly said.

"General, what is the plan, but it doesn't hurt to talk about it!" Wushu saw that it was Wanfu who was speaking, he was from Bohai and his surname was big, so he took advantage of him, and anyone had to call him a 'big' general.

"Taishi, at the end of yesterday, I will watch the battle, the naval army of the Southern Dynasty relies on its sharp firearms, but it is very afraid of fire, if we attack it with fire, we will be able to make contributions!" Big tart Buye said.

"Who doesn't know, it's just that the thunderbolts fired by our catapults are difficult to hit, and the rockets can't!" Wanyan Nie Er pursed his lips and said disdainfully, in the Jin army, it is also divided into three, six, nine and so on, the Jurchens are the regular army, and the Bohai people can only be regarded as miscellaneous cards, and the big tart does not dare to argue, and is embarrassed in the hall.

"Shut up, you think everyone is as stupid as you!" Wushu's eyes stood up, and he reprimanded Yan Yulie, "The general said, don't pay attention to those stupid people!" ”

"Master Xie! The last general thinks that it can be ...... like this," said Shi Li, who was grateful, and told his thoughts.

Wushu couldn't help nodding when he heard it, but he couldn't help but sigh in his heart, the Jurchens have been nearly thirty years since Taizu's anti-Liao state, but they have been fighting endlessly, and it is rare to recuperate, and almost all the Jurchen men have gone to the battlefield, and the victory has also led to a sharp decline in the Jurchen population, especially in the death of the older generation of Taizu, and the cutting-edge elites who should have picked up the burden have been exhausted in the internal strife, so that he has to rely more on these foreigners to support the situation, isn't it a kind of sadness......
