Xiao Yao and Zu Yan are both playing psychological warfare!

Zu Yan first used the empty city strategy, and remembered the effect of the suspicious soldiers, which made Xiao Yao take it lightly when attacking the city, and rushed into the city of Lanling County without warning! When the time comes, he will personally put on his armor and go into battle, not only can boost the morale of the soldiers, but also can scare Xiao Yao, when he sees a person who has been blinded by the world, he can ride a horse and shoot arrows, which will definitely surprise Xiao Yao and lead to chaos, then the ambush of the Qi army in the city will have a chance to win!

Compared with Zu Yan's somewhat complicated psychological warfare, Xiao Yao's psychological warfare is more direct and rude, that is, to crush the opponent with absolute strength, deter the enemy, and let them know that in front of Xiao Yao, they have only two ways to choose: surrender and death!

Soon, outside the city of Lanling County, the people who had raised troops and made trouble had withdrawn to the back of Chen's army, and Lu Guangda's infantry battalion had also surrounded Lanling County, and behind them, the four bronze cannons of Li Nong's artillery battalion had also been adjusted to the four gates of Lanling County!

Then Xiao Yao waved the flag, the signal cannon fired, and after a loud sound of the empty cannon, the four bronze cannons also followed the signal cannon and fired at the target one after another!

Boom Boom! Four huge explosions rang out on the four city gates of Lanling County! The tower on the city gate was also blown up by a grenade filled with yellow explosives, and the artillery battalion did not stop, immediately after firing a shot, it used a long-handled brush to clean the gunpowder residue in the bronze barrel, and then reloaded the gunpowder shells and continued to shell the city gate!

The artillery battalion fired a total of three rounds of grenades, and the whole process only took two minutes, but at this time, the city tower of Lanling County had also been blown up by the grenades and turned into a pile of ruins, drowning in thick gunsmoke!

And the officers and men of the infantry battalion who were standing in front of the artillery battalion and were in charge of besieging the city were also deeply shocked by the scene just now, and even Lu Guangda was stunned! He had heard that these cannons invented by Xiao Yao were very powerful weapons before, but because he had never fought side by side with Xiao Yao, he had never seen the cannon fire with his own eyes.

And just now, they were standing at the front, less than fifty meters away from the city gate of Lanling County, so when the grenade was fired on the city tower and exploded, the loud noise was deafening! The blast wave with the strong smell of gunpowder smoke made those soldiers holding shields feel it firsthand! There is also watching the city tower suddenly explode and fall apart and collapse in the smoke of gunpowder, so that these new soldiers under Xiao Yao's command can bring an all-round, three-dimensional impact visually, auditory, and tactile, so that they can truly realize how powerful these weapons invented by their commander are!

Before this, Zu Yan, who was over sixty years old, had also put on his armor and mounted his horse, and the Qi army behind him was also staring at the open city gate with full attention, when they saw the soldiers and horses of the Chen army running back and forth outside the city, the mood of these Qi soldiers was even more nervous and excited, and they were all gearing up, ready to fight to the death with the Chen army who rushed in!

However, when they saw that the Chen soldiers with this spear and thick shield in their hands were only in a defensive formation outside the city gate, and had no intention of rushing in at all, an ominous premonition suddenly rose in their hearts: these Chen soldiers seemed to be only surrounding them, so that they in the city had no chance to escape from the city!

And at this time, they heard a loud bang again, and they were even more frightened and panicked, and their souls flew away, because this loud noise was the sound of artillery firing like a nightmare in the hearts of the soldiers of the Qi army!

Zu Yan, who had just come to Northern Xuzhou, had never heard the sound of artillery, so he didn't know what this loud noise meant, but most of those Qi defenders were soldiers who followed Gao Changgong to fight Xiao Yao in Xiao County, so when they heard that the Chen army outside the city had begun to bombard, their faces showed terrified expressions!

Sure enough, after the cannon sounded, soon from the direction of the four city gates of Lanling County, there was an explosion that was louder than the loud bang just now, and three rounds came one after another! Looking up from afar, a puff of white wolf smoke rose from the four city gates, and the city towers that were fine just now have turned into a pile of ruins!

Of the 20,000 Qi troops now stationed in Lanling County, except for the 5,000 cavalry who participated in the Battle of Xiao County, who had personally experienced the power of artillery, the remaining 15,000 people had never seen the power of these artillery! They were all the same as the soldiers of Lu Guangda's infantry battalion, although they had heard how powerful Xiao Yao's artillery was before, but like now, seeing the power of the artillery explosion so closely and intuitively still made them fall into endless fear!

And although Zu Yan is blind, but when he hears the deafening loud noise, as well as the smell of gunpowder smoke rushing in his face, he can't help but feel a little fear, what kind of weapons are these artillery, why can they have such power, it seems that Gao Changgong is really not lying, these cannons made by Xiao Yao really have the power to destroy the world!

Although he had heard Gao Changgong write to Emperor Gao Wei when he was in Yecheng before, saying that the power of these cannons was enough to destroy the world, and even heavy cavalry like Baibao Xianbei could not fight against them, so he asked Gao Wei to fully support him in imitating these artillery, but because these officials in Yecheng thought that Gao Changgong was just exaggerating and wanted to deceive him of greater power and refused, including Zu Yan! A large part of the reason why he opposes it is that if they all use the little money left in the treasury to make gunpowder and artillery for you, then what are these corrupt officials greedy for?

When the artillery battalion completely destroyed the four towers on the city wall of Lanling County, Xiao Yao decided to send a force into the city to persuade the defenders in the city to surrender!

As a result, a persuasion force composed of musket battalion soldiers with Minnie muskets in their hands and cavalry battalion soldiers with sabers and spears in their hands rode into Lanling County with a high head and a majestic style!

"We are the forward brigade under the command of General Wei Lie Xiao Yao, and now you have been surrounded by us! In Lanling County, let alone you, not even a single mouse can escape! You have already seen the combat effectiveness of our forward brigade, and in less than a cup of tea, your castle tower was destroyed by us, so why should you fight with us! Your Qi army's so-called god of war Gao Changgong has been defeated once by our forward brigade in Xiao County, and nearly 10,000 people have died, do you still want to continue to fight against our forward brigade! ”

"You are now the turtle in the urn, and we will kill you as we want! But our commander Xiao Yao is a benevolent and righteous man, and he doesn't want to see you killed by us, and the blood is flowing like a river, so he specially sent us in to persuade you to surrender! ”

"If you don't want to die, put down your arms, raise your hands and go out of the city, and surrender to Commander Xiao, Commander Xiao promises a thousand gold, saying that if you don't kill you, he will definitely let you live! Last year, more than 10,000 Qi troops surrendered to us in Xuyi County, and now they have food, shelter, and fields to cultivate in Huainan, and they don't need to worry about being conscripted as soldiers and dying on the battlefield! That little day was even better than when I was in Qi Kingdom! ”

"If you want to live such a life, then surrender to our Commander Xiao! Time is limited, and if there are still people who are unwilling to go out of the city and surrender before sunset, then we will consider you to be loyal to your mediocre emperor Gao Wei, and are determined to fight us! But we don't care about any of that, and we're even a little excited, because we're going to kill you without hesitation, and then take you to a mass grave outside the city and bury you casually! ”
