In Guandu, Cao Cao asked Liu Ye to organize craftsmen to produce a pedal-style strong bow, and wanted to use this strong bow to give a fatal blow to the soldiers under Hao Zhao who was guarding the city of Guandu, so as to break Guandu in one fell swoop. Then the 200,000 army led by Cao Cao could cross the Yellow River, stand up and go into Hanoi, and head straight to Jinyang.

Of course, Cao Cao's army would not stop attacking the Guandu city wall by making foot-stick bows and arrows; after all, Cao Cao had 200,000 troops, while Hao Zhao's subordinates only had 10,000 troops; Cao Cao adopted the tactic of taking turns to attack Guandu city wall day and night, and did not want Hao Zhao's soldiers to have time to rest.

Cao Cao's army attacked the Guandu city wall day and night, which really caused great difficulties to Hao Zhao's soldiers. He Zhao originally did not want 5,000 of them to be used as infantrymen, but only 5,000 infantrymen of the Brutal Bear Army could not resist the attack of Cao's army day and night, so he had to let the iron cavalry participate in the defense of the city. This was still very exhausted by the Cao army's attack on the day and night, and the soldiers were exhausted extremely physically.

Cao's army's attacks continued, and no matter how much casualties were, they were forced to attack by the supervision team. Although they were hit hard by He Zhao's soldiers every time and suffered heavy casualties, they still remained the same and adopted a strong attack.

Hao Zhao prepared enough supplies to defend the city in Guandu City, especially the reserves of crossbows and arrows are inexhaustible. However, the stones used in the catapult cart consume too much, and it will not be guaranteed in more than ten days. Fortunately, there are sufficient supplies such as crossbows, tinders, and tinder oil, otherwise there will be big trouble.

Every time the Cao army attacked like an ant, and the crossbows on the city wall did not hesitate and fought back; the arrows made a sound of chirping! Chirping! Chirping!, and hit the Cao army's formation like lightning. Although the Cao army also had shields, the arrows emitted from the crossbows still seemed too fragile in the face of the extremely powerful crossbows. The attacking Cao army soldiers kept falling down, and blood was always accompanied by the pace of attack. As long as the Cao army soldiers shot by the arrows, they would be brought out a bloody flower, and some would splash on the bodies of the soldiers next to them.

Sometimes after Cao's attack was beaten, the city wall was covered with dense corpses of Cao's soldiers, with bloody corpses scattered underground, and there was no place to settle down. The blood was several centimeters deep. After the soil on the ground was soaked in blood, it turned into mud. Every time Cao's soldiers stepped forward and took a step back, they were like walking on a muddy road.

The Cao army soldiers who were struggling under the Guandu city wall were covered with dense arrows. No one would pay attention to these anymore. The Cao army soldiers would not care about it, and the soldiers under Hao Zhao on the Guandu city wall ignored it even more. Some of the bodies were hit by huge stones fired by catapults, and they became minced meat or missing arms and broken legs.

After the stones were used, Hao Zhao ordered all the catapults on the city wall to be transported down to the city wall, increasing the number of crossbow beds, which allowed nearly 100 crossbow beds on the Guandu city wall to fire ten crossbow arrows at a time, greatly increasing the degree of crossbow arrows, which did not affect the gap in the catapult exit.

Chi! Chi! Chi! Crazy crossbow arrows seem to be about to wipe out everything in front of you. After many days of attack, Cao's soldiers have also summarized some methods to defend crossbow arrows, that is, to evacuate the formation and allow the soldiers to disperse the attack, which can reduce the effective hit rate of crossbow arrows on the city wall.

The soldiers under Hao Zhao on the city wall didn't care about the arrows being transferred in. They still fired with all their might every time. The hundred crossbow beds were continuously firing, condescending, and their lethality was not weak to the Cao army. The Cao army soldiers attacked continuously, but each time they ended in failure. The Cao army soldiers knew in their hearts that they still attacked continuously.

Chi! Chi! Chi! Chi! The whistling crossbow arrows on the Guandu city walls were still shooting out, making the attacking Cao army soldiers feel very painful, and the battle between the two sides began to stalemate. Under the dense and fierce anger, even if the Cao army's supervisor team was fierce, they could not break through Guandu city. Every time they attacked, Cao army's siege equipment would be burned and countless lives would be left behind; while Cao army soldiers seemed to know that their destiny could not be escaped, so they could only go out to attack until they died and ended their lives.

Cao's army was willing to attack day and night without hesitation, and he would pay the lives of five or six thousand soldiers every day; but Cao Cao didn't care, as long as he took Guandu, this was different from the idea that Lu Ning's army attached great importance to the lives of soldiers. "Lu Ning would rather consume a lot of materials than letting his soldiers lose their lives. In Lu Ning's heart, people are the most important. Someone can do anything, and if there is no one, they can do nothing.

For more than ten days, Cao Cao lost nearly 50,000 troops in Guandu's attack, not including the tens of thousands of injured soldiers. After paying such a huge price, Cao's army had never even climbed up the city wall of Guandu. Every time, Cao's soldiers were eliminated when they climbed up the city wall. Most of the Cao's soldiers were solved under the city wall.

Hao Zhao's soldiers were at their most exhausted time. If no reinforcements came and Cao's army continued to attack like this day and night, I really don't know how long it would take to defend Guandu. Hao Zhao was also very anxious. The document of the emergency had been sent out long ago, but there has not been any reply yet.

Hao Zhao knew that the General Staff and the Ministry of War were more anxious than him, but without the approval of the cabinet, reinforcements could not be dispatched. This was not that there was no troops in Jinyang City, but that Lu Ning was not there. If you want to send troops, you must have the approval of the cabinet. Since receiving the military information, the cabinet has been arguing and has never reached a consensus.

Fortunately, with the intervention of Lu Ning's wife Cai Yan, the cabinet finally approved it, but this delayed the military information for more than ten days. If it weren't for the command of a general like Hao Zhao who was good at defending the city, Guandu City might have been captured by Cao's army long ago.

Liu Ye's foot pedal bow was made under Cao Cao. A large number of carpenters were recruited to make nearly 2,000 foot pedal bows in more than ten days. This is not a strong bow that can be pulled by hand. The strongest Cao army soldiers can only use their feet to kick them. The effective range actually reaches a terrifying 500 steps.

Liu Ye is said to be a descendant of the Mo family, and has some research on the traps and machinery of the production machinery. After all, the Mo family has always been a special project in this regard, and it is also the foundation of the Mo family. Liu Ye has related books handed down by the Mo family. Although it was rough for Lu Ning, it was really an advanced technical book for ancient times.

Cao Cao saw the craftsmen who made a strong pedal bow under the guidance of Liu Ye, and asked his guards to try it out with their feet. He found that the range was very long. Although the accuracy of using hut to open the bow was very poor, if the indiscriminate shooting was performed on the Guandu city wall, its power was still terrifying. After all, with two thousand such strong bows shooting at the same time, it would definitely cause great damage to the soldiers of Hao Zhao's guarding city on the city wall.

Cao Cao was very satisfied after seeing this, and immediately laughed and said, "Ziyang, if you can break through Guandu, you should remember your first merit."

Liu Ye smiled and said, "Lord, this is my duty, I dare not be greedy for merit."

Cao Cao said: "I reward you with a hundred gold coins!"

Liu Ye thanked him, "Thank you lord."
