After the Battle of Fushun, Zan Wanshou led a naval brigade and carried 1,000 Banzhou soldiers to Lingquan Mountain. According to the battle plan of the General Staff, he will join forces with Yang Wen and gallop to the defenders of Pengxi Village. It's just that the plan can't catch up with the change, and Kipchak suddenly led a large army to attack Diaoyu City, which made the surrounding battle situation abruptly change, and he had to send a clipper to explain the situation to Yang Wen, who was anxiously waiting.

Zan Wanshou is ready to assist Diaoyu City to break the siege as soon as possible, and then go north back to the water. The strategic location of Diaoyu City was extremely important, and Zan Wanshou was convinced that both Yang Wen and Ouyang Xuan would understand their temporary adjustment of the battle plan. Although the number of Mongol troops led by the Kipchak was far less than that of Meng Ge's personal expedition, Diaoyu Cheng purchased a large number of firearms from the Perak army, and Zhang Jue dealt with it properly, so it was safe to defend the city, but under the disparity between the enemy and our army, there were also many hidden worries.

One of the hidden worries of Diaoyu City is the lack of troops. After Liu Quan's rebellion, Yu Xing wantonly dispatched the elite of the Song army in eastern Sichuan to attack Shenjian City, and many fortified cities were insufficient due to too many troops. Diaoyu City was no exception, 2,000 of the 5,000 soldiers in the city were siphoned off, most of these elites died under the Divine Arm City due to Yu Xing's incompetence, and only a few dozen people fled back to Diaoyu City. The reduction in troops led to Zhang Jue being able to defend passively and was unable to take the initiative to attack, resulting in the loss of peripheral strongholds. Kipchak listened to the advice of Zhang Dayue, the defender of Yunshan City, and began to build a fortress and dig a trench in order to besiege the Diaoyu City.

One of the hidden worries of Diaoyu City is the loss of water advantage. The new attached generals of the Mongolian Army's Dongchuan Marshal Mansion, Zhang Dayue and Pu Yuangui, all have naval armies. Although Yang Dayuan was far away in Pengxi Village, he also sent a naval army to participate in the battle. These new annexed armies had a total of 300 warships and more than 2,000 sailors, more than twice the size of the Diaoyu City navy. The superior strength and the Mongolian cavalry fired rockets from the shore, and the Diaoyu City naval army was defeated and retreated, so they had to move under the cover of the artillery of the city wall. It's just that the artillery is high in the middle of the mountain, and the firepower cannot cover the entire river, so that the Mongolian army has a clear advantage in the waters around Diaoyu City.

The Mongol army not only blocked most of the Diaoyu City's communication routes with the outside world, but also threatened the waterway for the Perak army to reach the Fujiang River. Therefore, although the military situation in Pengxizhai was urgent, Zan Wanshou also had to send someone to contact Zhang Jue to prepare to solve the Mongolian army. The solution in Zan Wanshou's mouth is not to retreat, but to ensure that they are all wiped out or severely damaged, so as to prevent them from posing a threat to the water transportation lines of the Perak Army and even to the warships. Although these warships of the Mongolian army were small in tonnage and did not have firearms, they were numerous and difficult to deal with if the tactics were right.

Zhang Jue still sent Wang Li to lead the Diaoyu City Naval Army to cooperate with the Perak Army. Wang Li first took the initiative to attack, inducing the Mongolian army to pour out the nest, and then pretended to be defeated, and retreated to the downstream of the confluence of the three rivers in Diaoyu City. The water here is deep and the river is wide, which is very suitable for large warship activities. Although the Mongol navy has had an absolute advantage over the Diaoyu City naval army since the siege, it did not dare to approach too much because of the artillery on the city wall. Seeing that the Diaoyu City naval army was far away from the protection of artillery, they chased after each other by boat, and unknowingly chased more than ten miles.

After chasing a river bay, the Diaoyu City warships suddenly stopped, and behind them, there was a row of warships across the river. The ships were extremely tall, with the Thunderbolt Army flag and the "Zhan" flag flying high on the mast, and each of their open portholes revealed a black cannon.

As he said, "I have never eaten pork, and I have seen pigs run". The general of the Mongolian army was called Zhang Tingrui, and although he had not seen artillery warships, he had also heard of their power. Seeing this situation, he knew what he was planning for, and urgently ordered the rear team of the whole army to be the front team and return to the army as soon as possible. While the Mongolian ships were in disarray, the artillery ships opened fire. The cannonballs crossed the Diaoyu City and fell into the dense Mongolian warships, and under the roaring shells, more than a dozen ships sank into the water in an instant, and many more ships were on fire.

The Thunderbolt warships fired not only hot solid shells, but also incendiary bombs with oil residues, which were a new type of artillery shells specially designed to deal with warships. Under the guidance of Ouyang Xuan, the fire well in Qiongzhou has been dug to a depth of hundreds of meters, not only the amount of gas has increased greatly, but also the fire oil has been excavated, but the yield is not high, and the quality is not as good as the fire oil brought by the Mongolian army from the Western Regions, and it needs to be distilled repeatedly and too much before it can be used. This distilled residue is an important raw material for the production of combustion-boosting bombs.

The soldiers of the Mongolian Navy were so frightened that they desperately rowed their oars and fled upstream. Just as they managed to escape from the range of the ship's guns and were glad to have escaped, several unmanned boats floated down from the river upstream. As the boats approached closer and closer, more than a dozen artillery warships slowly sailed out of the river upstream. The attention of the Mongol soldiers was attracted by the artillery ships ahead, and no one noticed that the small boats had drifted into the flotilla. When he realized that the large iron ball contained in the boat had a lead burning inside, he suddenly remembered that this was the legendary self-detonating ship.

Frightened, some of the Mongolian soldiers jumped into the water, some jumped into the boat and picked up knives and axes, and some had flexible brains and called their companions to overturn the boat. It's just too late, and even if it sinks into the water, the iron ball doesn't stop burning, but still bubbles out. A few breaths later, an earth-shattering explosion erupted amid screams and shouts.

The thick smoke and mist formed by the explosion dissipated, the air was still filled with the pungent smell of gunsmoke, and the noisy and noisy river suddenly became much quieter, and the river was full of broken wood, boat planks and human wreckage, and the river water also turned a dull red. At this time, the artillery warships had stopped firing, and in addition to the reason that the barrel was overheated and needed to be cooled, there was no need to open fire. The concentrated fire and self-detonation of the boats had destroyed one-third of the Mongolian warships, and some of the Mongolian soldiers were huddled together and shivering, some were stunned, and only a few of them jumped into the water and swam desperately to the shore.

I originally thought that the desperate battle was so one-sided, which not only shocked the Mongolian soldiers, but also greatly surprised the Diaoyu City water army. It is said that the soldiers of Diaoyu City also knew the great power of the artillery, and they also used the cannon to inflict heavy damage on the Mongolian army, but they did not witness the concentrated fire of the heavy artillery. The power of those inconspicuous self-detonating ships is even more devastating. In fact, the self-detonating ship not only destroyed the warship, but also destroyed the spiritual will of the Mongolian soldiers. At this moment, Wang Li secretly rejoiced in his heart, glad that he and Ouyang Xuan hit it off at first sight, and glad that Diaoyu Cheng and the Thunderbolt Army were allies, not enemies.

The battle took a quarter of an hour, but it took an hour to clean up the battlefield, because there were so many captures. None of the more than 300 ships of the Mongol army escaped the net in this battle, and all but those who were damaged were captured, and the number was fully 210; More than 2,000 sailors were captured alive and 1,500 were taken prisoner, and they were to be transported to Jiantandu and Lingquan Mountain as labor for the next step in building the fort. The rest of the hundreds of Mongolian soldiers were killed or drowned in the water, and only a dozen escaped, including Zhang Tingyi.

On the other hand, the losses of the coalition forces this time were slight, and it is not an exaggeration to say that it was a dimensionality reduction blow to the Mongolian army. The Diaoyu Navy lost more than a dozen ships and more than 100 sailors in the process of luring the enemy, while the Perak Navy lost no ships, and only a few were injured - either from being smashed while carrying shells or scalded by the scorching barrels while loading ammunition.

After the total annihilation of the Mongolian army's naval army, the next step was to break the siege of the Mongolian army on Diaoyu City. Zan Wanshou did not stay to clean up the battlefield. As soon as the battle ended, he and Wang Li led the main force to the north. At the head of the fleet were still the Diaoyu Navy, whose ships were small and familiar with the waterways, which could prevent the remnants of the Mongol ships from raiding the Thunderbolt artillery ships. The Thunderbolt ships were large in size and did not turn as flexibly as small ships, making them very vulnerable to attacks by small ships such as enemy fire ships. Wang Li also knew that artillery ships were very expensive, so he offered to escort them at the forefront.
