The next day, Cao Cao led a large army to Guandu City and carried out a tentative attack on Guandu City as planned, with the purpose of understanding Guandu's defense capabilities. After all, he was not clear about Guandu's defense capabilities. He only knew that Guandu's wall was high and thick, and it was a urn city with 10,000 troops stationed.

When Hao Zhao saw Cao Jun who was dark under the city, he smiled slightly, and wanted to break through Guandu City, dream!

After years of construction, Guandu has very strong defense capabilities. Hao Zhao knew very well. Chang'an City Wall is only 6 meters high, which is already the thickest city wall in the Han Dynasty. The city wall that can be built is as high as 12 meters and 3 meters thick. It is close to the Yellow River to the north. It is really not easy to break through.

Cao Cao asked Yu Jin to lead 5,000 infantry to attack, and Xiahou Dun, Cao Hong and others led a large army to suppress the rear; and Cao Cao himself also went to the front line and personally directed the attack.

Yu Jin was one of Cao Cao's five good generals in history. His abilities are absolutely first-class. He can establish himself in Cao Cao's talented camp. Those are all masters among the masters, and they are not worthy of being famous.

Yu Jin was not only good at siegeing cities, but also good at defending cities, so there is no need to question this; especially in terms of training soldiers, Yu Jin was the best master in the Three Kingdoms period; being able to turn 300,000 Yellow Turban Army was actually a farmer who left his hoe and trained into extremely powerful Qingzhou soldiers in a very short time, which fully demonstrates that Yu Jin's ability was very excellent; during the Three Kingdoms period, Yu Jin was definitely among the best in training soldiers.

Yu Jin sent engineers to clean up various traps in front of him, which was a very difficult task; Hao Zhao had already laid various traps within 500 meters in front of Guandu City Wall; and the attack distance of the crossbow bed within 500 meters. If you clear these traps, you will face the attack of the crossbow bed, and you will also face the attack of the catapult cart within 300 meters.

Cao's army had no choice but to clean up those traps of the mechanism, so they could not attack. When Yu Jin's engineers were cleared, the things on the surface were easy to clean, but the traps of the mechanism were not easy. From time to time, engineers fell into the trap and were stabbed in the soles of their feet. There were bamboo tips and wooden thorns in the trap. The chances of falling into it were not very high.

Cao's army carefully cleaned up the traps of the organs. Although there were screams, screams, and crying sounds from time to time, they did not stop Cao's army from time to time.

Hao Zhao stood on the wall of Guandu and saw that with a wave of his hand, dozens of crossbow beds pulled the machine with Zhao Hao Zhao's hand gestures; hundreds of thick and powerful crossbow arrows pierced into the Cao army like lightning; some Cao army soldiers were pierced by powerful crossbow arrows and nailed to the ground, and some crossbow arrows would penetrate the Cao army soldiers behind them together, and the most could penetrate four or five people.

The fierce crossbow arrows made the Cao army's formation in chaos, and screams sounded. Although there were not many Cao army soldiers shot, the lethality was too scary, which made the Cao army soldiers frightened and their morale was low. The Cao army soldiers fled back one after another, fearing that if they were slower, they would be penetrated by the crossbow arrows.

This crossbow bed is Ma Jun's fourth-generation product, with a range of more than twice as high as the original generation product, and its lethality is greater. Each crossbow bed can fire two to five crossbow arrows, which needs to be adjusted according to the distance of the attack; at about 500 meters, the crossbow bed can fire at most two crossbow arrows at the same time. If it is closer, there is no problem with five. Moreover, the crossbow bed adopts the principle of shaking the gears, which greatly reduces the difficulty of using crossbow arrows, and can complete a single shot within 10 yuan clock, which is slightly faster than the speed of ordinary bows and arrows.

After seeing the central army, Cao Cao immediately ordered Yu Jin to the messenger beside him, and asked the army to clean up the traps of the organs immediately. After receiving the order, Yu Jin smiled bitterly and immediately directed the army forward to clean up the traps of the organs in front of the formation as soon as possible.

After killing several soldiers who fled backwards, Yu Jin's army pressed forward under high pressure, and at all costs, he had to clean up the traps in front of the formation in the shortest time.

Hao Zhao on the Guandu city wall was not in a hurry, and only asked the crossbow bed on the city wall to shoot, and at the same time ordered the snipers to snipe the officers of the Cao army.

After receiving the order, more than a dozen snipers immediately raised their sniper crossbows in their hands and shot and killed the middle and lower-level officers in the Cao army. This was disastrous for the Cao army. The small leaders around the Cao army fell down one after another, causing chaos immediately. The Cao army soldiers were like headless flies and lacked the command of middle and lower-level officials. No matter how capable you are, it would be useless.

When Yu Jin saw that his middle and lower-level officials died one after another, he felt depressed. How could there be so many sharpshooters in Lu Ning's army? Since he can still shoot so far, is this a human?

In ancient times, even an archery expert like Huang Zhong could shoot the opponent within 200 meters, which would be very powerful. If you want to shoot at a distance of 500 meters, it would basically be impossible. The arrows would not be so far. Even if they shot so far, they would not have any lethality. But what about the sharpshooters in Lu Ning's army? They can not only shoot so far, but also hit the target. This is too inconceivable, especially there are so many sharpshooters, which makes Yu Jin really dizzy.

Yu Jin adjusted the formation, let the shield soldiers step forward, and used the shield in his hand to cover the soldiers to clear the traps in the mechanism ahead. Although this could have a point of effect, the snipers under Hao Zhao could no longer effectively hit the target, but the crossbow bed still blocked the shields. The shields in the shield soldiers' hands would be penetrated by the finely decorated crossbow arrows.

Under Yu Jin's high pressure, the soldiers under his command still stepped forward one after another, but the speed was very slow, losing hundreds of soldiers, but they only advanced more than ten meters, which was completely filling the pit with the soldiers' bodies.

All morning, Yu Jin's soldiers advanced less than 30 meters, and suffered casualties from 1,500 soldiers; Yu Jin's heart was bleeding. If this kind of advancement, it would not take long for the 5,000 soldiers under his command to consume them, and even Li Peng's hair was not touched by the other party. Can Yu Jin not be depressed?

Cao Cao looked at it all morning and saw that his soldiers were suffering too much and their advancement was too slow. He had no choice but to call the gold to withdraw his troops and had to find a way again. This would definitely not be possible.

After Yu Jin led his troops back, he immediately ran to Cao Cao and said, "Lord, Yu Jin is incompetent, and he has let you down."

Cao Cao could see clearly from behind and knew that this was not a fault for Jin. After all, there were too many traps in the front and he was also facing the attack of Lu Ning's crossbow bed.

Cao Cao smiled bitterly and said, "Wenze, it's not your fault, but how could there be such a powerful crossbow bed in Lu Ning's army? Since it can shoot so far? The big man's crossbow bed has been around, but it's only about 500 steps."

Yu Jin smiled bitterly and said, "Lord, the crossbow bed of Lu Ning's army is not only long-range, but also has a very fast shooting speed and is indeed very powerful. I don't know why. The most troublesome thing is that there are a large number of sharpshooters in Lu Ning's army who specifically kill middle and lower-level officials in our army."

Cao Cao was far away and didn't know what happened.

Cao Cao said in confusion: "Wenze, you said there are sharpshooters in Lu Ning's army, but is it useful to have such a long distance?"
