Cao Cao laughed at Deng Ai on the other side, and Deng Ai just silently watched Cao Cao on the other side of the river. Standing on the hill and looking at the opposite bank, Cao Cao's soldiers and horses on the opposite bank covered the sky and the sun no less than 30,000 people. Although Deng Ai lost 5,000 elites who saved Cao Cheng, there were still 7,000 men and horses in the main city of Bianjing, and 4,000 men and horses in the deputy city of Fengqiu, so he didn't know how much Cao Cao was. Cao Cao ordered the army to cross the river, and after the order was given, hundreds of people began to try to cross the river. The hundred men walked cautiously forward with their shields, and when they reached the middle of the river, suddenly a loud noise sounded, and the ice on the river was blown up, and nearly half of the soldiers were killed, and the others generally fell into the river and drowned. Seeing the explosion in the river, Cao Cao was stunned, what is going on?

When the soldiers saw the river explode, none of them had seen it, thinking that the river god was angry, and they all knelt on the ground in fright and begged the river god for forgiveness. Although Cao Cao did not believe in the river god, for some reason, he saw that the soldiers had no desire to fight, so he had to retreat temporarily. After staying by the river for two days, Guo Jia said that this must be Tao Ying's latest invention of the bomb, since it is a bomb, it has nothing to do with ghosts and gods, and you can continue to cross the river!

Cao Cao listened to his words and ordered the soldiers to cross the river, but after encountering mines in the water and killing nearly 100 people, the soldiers hurriedly ran back. Guo Jia also suggested that it is better to fill the river with soil, and he doesn't have to be afraid of any bombs! So Cao Cao sent people to dig a map to fill the river, but the soil was frozen in winter, and he couldn't dig it at all. Cheng Yu suggested that it is better to take a detour and bypass the river!

So Cao Cao ordered Cao Chun to lead 10,000 troops to bypass the river to attack Bianjing, and after Cao Ren led the troops away, Cao Cao continued to attract Deng Ai's main force on the other side of the river. After several attempts, the mines in the river were stepped on, and Cao Cao worshipped the water god by the river and tricked the soldiers to cross the river. So nearly a thousand soldiers swarmed to cross the river in boats, and when they saw that the mines were gone, Deng Ai had people set up cannons to blow up the boats in the water, and a war of attrition began again.

Cao Cao spent ten days with Deng Ai on the other side of the river, and after Deng Ai blew up nearly 1,000 Cao Cao, suddenly a battle report came from Ma Jian in the rear, saying that Cao Chun had led his troops across the river from the north to the west of Bianjing City! Deng Ai was afraid that Bianjing would be breached, so he hurriedly led his troops to reinforce Bianjing. Seeing that Deng Ai was gone, Lu Xiangbu, who had just crossed the river, hurriedly pursued Deng Ai.

Lu Xiang just caught up with Deng Ai's old, weak, sick and disabled army, and suddenly the rear army was in chaos, it turned out that this was Deng Ai's strategy again, he used the old, weak, sick and disabled to attract Lu Xiang's lone army to go deeper, and ambushed the elite soldiers and horses behind, and when Lu Xiang entered the encirclement, he killed from behind.

In the first battle of Songjiazhen, Deng Ai annihilated nearly 1,000 people and horses of Lü Xiang, and captured Lü Xiang, and then led the troops back to Bianjing. After Deng Ai returned to Bianjing, he hurriedly ordered Ma Jian to guard Fengqiu City and guard Bianjing City himself. In order to be able to keep Bianjing City, Deng Ai recruited troops on a large scale, and the major families had to let their soldiers go into battle to kill the enemy in order to keep their property, so in just half a month, Deng Ai recruited nearly 20,000 troops in Bianjing, and Ma Jian recruited nearly 6,000 troops in Fengqiu, and the total number of soldiers and horses on both sides was nearly 26,000, which was only more than 4,000 less than Cao Cao's soldiers and horses.

The three cities of Bianjing gathered one-twentieth of Yanzhou's population, so relying on the population advantage, Deng Ai decided to fight Cao Cao! This great hero in the world, if he can hold Bianjing, then even if he wins him, he will definitely become famous in Xuzhou, and even in the world! Looking at Bianjing, Bianjing is difficult to defend and easy to attack on the plain, but Bianjing also has its own advantages, that is, the army and the people are united.

The time, the location, the people, Deng Ai will not occupy the advantage. Now the north is still cold, Cao Cao's army is stationed outside the city and is infected with typhoid fever, and Yanzhou's medical level is poor, and there are no less than 20 people dying every day, so after recruiting soldiers and horses, Deng Ai announced that he would not leave the city without leaving the city, and when Cao Cao's grain and grass were exhausted, he would naturally retreat!

Cao Cao led the troops to Bianjing outside after crossing the Bianshui, Cao Cao never came to Bianjing, but he heard others say how majestic he was, and now it is really shocking! Bianjing City is nearly seven meters high, the city walls are all brick walls, and there is a moat outside the city wall, that is, you can see the towering buildings in the city from a distance outside the city, row after row, each high-rise building is much higher than the city wall.

"If you get Bianjing, it can be the capital!"

Looking at the magnificent Bianjing, Cao Cao couldn't help but say. That's right, the design of the entire Bianjing City was designed by the Xuzhou Design School, and his specifications were built with the specifications of the capital, but not the capital of the Han Dynasty, but the capital of Yanzhou Mansion!

Cao Cao came to Bianjing City, and everyone persuaded Deng Ai to take advantage of Cao Cao's exhaustion to fight with him, Deng Ai did not listen, Deng Ai said that Cao Cao was scheming and strong, and he could not be defeated! The generals did not listen, and some people went out of the city to meet the battle without authorization, and they were surrounded by Cao Cao's ambush, and nearly 3,000 soldiers and horses out of the city were killed by Cao Cao's army and less than 100 people ran back, and the main generals were captured.

Deng Ai had no choice but to exchange Lu Xiang for his generals, and since then, the generals have never dared to fight easily. Cao Cao rested outside the city for a day and then began to attack Bianjing, Deng Ai hoarded enough grain and grass in the city to eat the army for two years, so he was not in a hurry to organize soldiers to fight the city wall while letting the generals continue to train the soldiers.

So I saw such a scene in Bianjing, where the sound of cannons rang out in the sky, but the sound of reading and the sound of drills could still be heard in the city. Cao Cao's army and horses attacked the city several times, and each time they were bombarded by artillery before they reached the city, and suffered heavy losses. Cao Cao set up a cannon to bomb Bianjing, only to find that his cannon had just been erected, and his cannon was blown up with one shot.

After nearly seven years of transformation, the Taoling cannon has now been upgraded to the seventh generation of cannons, and Cao Cao's cannon is still a generation of cannons. Seeing that the cannon was not strong at all, Cao Cao could only drop the cannon and attack by other means. Guo Jia saw that he was losing nearly 100 people a day, and that he would not lose his morale for months if he continued to consume it, so he suggested to Cao Cao that it was better to lure him out of the city.

So Cao Cao stopped attacking the city, and scolded Deng Ai outside the city every day for being a turtle with a shrunken head, that is, no matter how good the city construction is, he is a coward and loses the face of his ancestors. In order to humiliate Deng Ai, Cao Cao even had his soldiers unbuckle their armor and bathe in snow outside the city. When the soldiers of Bianjing saw it, they were so angry that they had to go out of the city to teach Cao Cao a lesson, Deng Ai was afraid of the scheme, so he was busy appeasing the soldiers, but where did the soldiers listen. Seeing that the soldiers were asking for war every day, Deng Ai had a headache, but at this time, the useless Taishou came up with the idea that it was better to let the students in the city go to the city to study to fight against Cao Cao!

Deng Ai hurriedly applauded when he heard this, which not only allowed students to experience the profound meaning of reading to serve the country, but also allowed his soldiers to follow and read the book of sages, and at the same time let Cao Cao's soldiers and horses know their own state of etiquette, and make it difficult for them to attack the city, and then Deng Ai will use other methods to break their hearts!
