As the main cannon of the North Fort, it was heavy and huge enough to dwarf the little ones who were cooling in the hands of both sides.

Caressing the cold cannon body, such a huge body is rare in this land. But Chen Kai knew very well that the behemoth in front of him actually had six twins, not only the shape was exactly the same, but the inner wall and external dimensions were not different, and even the scratches and words on the cannon body were carved out of a mold.

Deliberately, as if all this was a spell containing magical power, Chen Kai didn't know whether to praise the craftsmanship of the craftsmanship, or to laugh at the misunderstanding caused by ignorance. But in any case, the six giant cannons that were later copied and the spiritual object that was said to be able to shoot a hundred shots with just a prayer were more accurate than ordinary front-loading smoothbore cannons.

There was only one gate on the North Fort, and the other gate in Chen Kai's hand was installed on the South Fort, because he really couldn't accurately predict the key attack direction of the Qing army. However, this second defensive battle of Lu Fengleng Fort has reached the point where it is now, and the general trend is all within Chen Kai's expectations, and even this is the result of his intention.

As early as the capture of the Jieshi Acropolis, Chen Kai did not choose to continue to recover the county seat of Haifeng that was already within reach. The reason for this was to leave the Qing army in Guangdong the last stronghold east of the Lotus Mountains. As long as this stronghold exists, the Qing army will inevitably use it as a bridgehead to attack Chaozhou, because the flat terrain is far more conducive to the Qing army's cavalry superiority than mountains and jungles.

For this reason, the Qing army kept the county seat of Haifeng, but it was bloodied in the first attack and defense battle of the Lufeng Twin Fortresses. Whether it was the two green battalions from the conquest or the feudal soldiers of the Jingnan Domain, they all lost a large number of soldiers.

In the same way, when the news of Guilin's victory forced Geng Jimao to withdraw his troops in a hurry, Chen Kai strictly ordered all towns not to attack, first, not to capture Haifeng County, and second, to ensure that the seventy-three Hongyi cannons must be in the hands of the Qing army. Because, as long as there is hope that the Hongyi artillery can be relied on to bombard the collapsed fortress, the Qing army will definitely come here again, instead of attacking Chaozhou from other directions. Even, even the sea trade route that went to Hong Kong to block the two feudatories of Pingnan and Jingnan also had the intention of forcing the Qing army to come here for a decisive battle.

The confidence in using Hongyi artillery to collapse the fortress is a solidified thinking that has been formed since the Qing army entered the customs, and even when it was in Liaodong. It is Yangzhou, Jinhua, Guangzhou, Tashan Xingshan, and it is the confidence that the fortified cities that were destroyed by the Hongyi artillery of the Qing army have established for them.

However, the old city wall in the Middle Ages was not used to fight artillery, but to face the siege army of cold weapons, and now Chen Kai took out the fortress to defend against the war of hot weapons, and the Qing army's Hongyi artillery collapsed the city wall, and then the tactics of the army immediately lost its inherent rhythm. What's more, the Qing army has Hongyi artillery, and this Ming army has never been an isolated existence, through sea trade and self-casting, not to mention the old foundation of the Zheng group, even in the case of two-front combat, they also have the scale and caliber of artillery that is not inferior to the Qing army.

Because of this, at the beginning of the construction of the fortress, Chen Kai had already admitted to the generals that Haifeng County was a bait, and the Lufeng twin fortresses were traps for catching animals. And now, the battle situation has reached a stalemate, and it is the best time for the clamp to fall!

"Let the troops on the east bank cross the river, and prepare the cavalry inside the fortress."

The flag behind the main battery waved, and the troops on the east bank of the Luo River who had been waiting for a long time stepped onto the pontoon bridge and marched towards the west bank. In the open space of the river beach between the west bank and the fortress, there are two war towns that have been hidden behind the huge bodies of the two fortresses in the north and south respectively, and the order is issued at this moment, under the command of the old partners of Lang Deng and Zhou Quanbin, one bypasses the fortress from the east of the north fort to the north, and directly attacks the Huang Yingjie division of the Huizhou general army who stormed the northwest of the north fort, while the other is from the south fort to the north, interspersed with the green battalion of the Dongguan general Zhang Daoying's department that is attacking the southwest wall of the north fort.

Under the fierce offensive of the Qing army, regardless of casualties, the Ming army finally reacted. Geng Jimao took the telescope and looked into the distance, and with the quick return of the Tanma, he quickly figured out the deployment of the Ming army.

"Lord Wang, this energy can't be vented!"

In Xu Degong's view, as long as it continues to be consumed like this, even if the casualties are much greater, as long as the Ming army's fort garrison troops are consumed to a certain extent, they can also completely overwhelm the defenders. But if you retreat like this, it means that all the previous achievements will be lost, especially the lost artillery and artillery crews, which will be difficult to recover for a while.

"On the north and south lines, each transfer a few cattle to press those green camp waste!"

Geng Jimao made up his mind, and Xu Degong hurriedly dispatched, and in each direction, 500 cavalry and 1,000 infantry were dispatched, counting those on the central battlefield, and the tens of thousands of troops in Jingnan Domain had been pressed by nearly two-thirds. And the rest are already the last reserves of the Jingnan Domain.

The Hongyi cannon is still cooling, but even if it cools down, it will be difficult for the Qing army to shoot in the direction of the fortress, lest it will cause accidental injuries and affect the morale of the army. However, on the side of the Ming army, they are condescending, and as the defensive side, they are not involved in accidental injuries, but they can be more unscrupulous.

This gap was even more embarrassing for the Ming army, Xu Degong was busy while mobilizing the feudal soldiers to step forward to cooperate with the green battalion, and on the other hand, he had to transfer the Hongyi artillery out of the range of the Ming army. On the other side of the battlefield, as another pillar under the Jingnan Domain, Lian Decheng was urging the feudal soldiers to increase their attacks, but the siege equipment in his hand was used less and less, but it really made him anxious.

The Ming army assembled on both sides of the North Fort and quickly adjusted the formation, and at the same time, the South Fort side was even more open, and a Ming cavalry under the banner of the Iron Cavalry Town came out of it, and it was even more with Zhou Quanbin's forward rush to form a flanking attack on Zhang Daoying.

The reinforced feudal soldiers caught up as fast as they could, but the infantry of the Ming army suddenly came out, but it was even better. The offensive against the southwest and northwest directions continued, and Huang Yingjie and Zhang Daoying continued to put pressure on the fortress while organizing the interception of the Ming army outside the city. The feudal soldiers have done their best, and the two green battalions have also fought hard, and Huang Yingjie and Zhang Daoying have coincidentally brought their own soldiers to the forefront, ready to fight to the death with the Ming army.

The battle outside the city broke out on both sides in an instant, and Zhang Daoying rushed to the front where he could get close to boost morale like crazy. However, once the battle was engaged, the rattan players of the Ming army in groups of three immediately launched an almost one-sided slaughter of the green battalion soldiers who were still unable to adapt to this style of play, and the formation was quickly torn and bitten like wolf teeth and dogs. And those feudal cavalry who quickly rushed up to help the battle were also entangled by the Ming cavalry halfway, and they couldn't get close to the battlefield on the south side of the North Fort for a while.

Zhang Daoying is still struggling to support, so desperate, the last time seems to be before the Qing army entered the customs. But at this moment, he knew that Geng Jimao's crazy attack was to get back the face of Jingnan Palace, how dare he not fight desperately in such a situation.

Around the North Fort and the city walls on the southwest and northwest sides of the North Fort, the battle between the two armies has completely entered the white-hot stage. Rao is Chen Kai, who lacks some actual combat experience compared to many generals present, can also clearly see that at this moment, both sides have used their strength to the extreme, but any wind and grass will lead to an instant overturn.

Looking anxiously at the rear, the follow-up troops were still slowly stepping across the pontoon bridge, the strength of the Ming army on this battlefield was constantly increasing, and it was nothing more than a matter of time before the two green battalions were completely overwhelmed. But now in the battle, the madness of the feudal soldiers has been unmistakable, Rao has achieved an unimaginable exchange ratio with the help of the fortress, but the casualties of the defenders are still rising.

"It's time!"

Chen Kai, who was already sweating profusely, shouted loudly, and when he snatched the torch from the hand of the main gun commander, he pressed it on the fuse.

The main cannon of the North Fort is a secondary gun for the Spirit. Not only was the bronze cannon larger, but it also weighed twenty-four pounds like a magic cannon. More importantly, in terms of range, this 24-pounder cannon is far superior to the 12-pounder and 18-pounder guns used by the Ming and Qing armies in the earlier confrontation, and the most lethal thing is that the main position outside the artillery position of the Qing army is also completely exposed to the firing range of this giant cannon, and even Geng Jimao, the king of Jingnan, is no exception!

It was the prince of Jingnan who was targeted, and once Geng Jimao died, the Qing army would inevitably be defeated immediately. This is like the conclusion of the alliance of Tanyuan in the Song Dynasty, and there is no lack of the Song army's eight bull crossbows sniping the famous general of the Liao army, Lanling County, the king of Nanjing, and Xiao Darin, the commander of the army. And Chen Kai never thought of concluding an alliance, but wanted to use this to discount the backbone of the Jingnan Domain here!

The cannon roared, the smoke of gunpowder erupted, the huge cannon was shaken, and the huge cannonballs shot out like lightning. Condescendingly, the cannonball crossed a smooth parabola in the air, and then directly crashed into the main position of the Qing army. Everything seemed to be happening as Chen Kai expected, but as the breeze blew, the gunpowder smoke quickly diluted into the air, and Chen Kai noticed the black trajectory along the parabola of the cannonball, and even before the cannonball landed, his heart was cold.

"Crooked!"

The front-loading smoothbore cannon, Rao is as accurate as the spirit gun, and the target is nearly two miles, and at most it is that area. Chen Kai took Geng Jimao as a target in line with the principle of taking the law from the top and the law from the bottom, and did not intend to kill Geng Jimao with one shot, as long as the shells could fall in that area, the shock to the Qing army was enough to cut off their morale.

But the cannon shot was a little too crooked, so crooked that it was out of the edge of the area, and at most it was just to scare them with this hidden range, which was much less effective than expected.

However, the chuckle in his heart had not yet landed, and Chen Kai looked at it again, and the area where the shell hit straight was originally just an open space, but at this moment, it seemed to be the area where the Qing artillery team had retreated. And in that area, there were not only Hongyi cannons, but also retreating shells and gunpowder......
