After dinner, Cao's army continued to attack Guandu City, and the offensive was extremely fierce, and he invested 20,000 troops to attack the city at one time. Hao Zhao stood on the city wall and smiled slightly, knowing in his heart that Cao's army wanted to take a continuous offensive so that the Lu Ning soldiers who were defending the city could not rest; after all, Cao's army had more than 200,000, while Hao Zhao had only 10,000 soldiers guarding the city, half of which were Feixiong Army.

Faced with the strong attack of Cao's army, Hao Zhao didn't talk nonsense, arranged various firepower to effectively defend, fully utilized the power of the crossbow, and gave a heavy blow to Cao's army.

In order to ensure the physical strength of the soldiers, Hao Zhao asked his soldiers to take a ferry to rest, stubbornly block the Cao army's attack, and prepared all kinds of defensive ammunition. The oil pan never extinguishes the fire, and the boiling hot oil is ready at any time. As long as Cao's army attacks under the city wall, immediately pour the boiling oil water in the oil pan into the city wall, and then shoots it with a rocket, and a raging fire will immediately ignite under the city wall.

After Cao's army attacked next to the city wall, the crossbows in the hands of Hao Zhao's soldiers showed their might. Five to ten crossbow arrows were shot out at each time, and their lethality was very terrifying. Thousands of crossbows were shot at the same time, and a large area of ​​Cao's army under the city wall would fall down.

Although the catapult cart cannot kill many Cao's soldiers, it is too powerful. As long as the big stone hits the brain or smashes it into minced meat, this is very effective in the morale of Cao's army and will cause a huge shadow on the hearts of Cao's soldiers.

The battle was fierce, the sound of fighting, the howling of dying people, the screams of soldiers, the collision of weapons, and the shouts of shouts were intertwined, making the original quiet night deafening, turning this place into a field of iron and blood. Blood splashed everywhere, and the broken limbs and broken arms flew around. Every moment, people roared and fell down. The noise was so loud that anyone would be terrified when they saw it.

Lu Ning was a time traveler, and of course he knew the importance of long-range weapons to war; in ancient times, bows and arrows were actually the only long-range weapons and equipment; this has always been valued by Lu Ning, and he was very concerned about the development of long-range weapons such as crossbows, stone-catted countries, crossbow beds, compound bows, etc., and he has always spared no expense or cost in weapon research.

In Lu Ning's mind, the problem that can be solved with long-range weapons is absolutely unwilling to let his soldiers engage in close-fitting hand-to-hand combat; although the armor, helmet and other defense capabilities of the soldiers under Lu Ning's army are very high, and the swords and guns in their hands are also very good, for close-fitting hand-to-hand combat, no matter how good the defense is, there will be casualties, and it will not be taken if it can avoid close-fitting hand-to-hand combat.

Therefore, although the number of soldiers in Lu Ning's army is not large, they are all elite troops and never pursue quantity. In addition, the soldiers in Lu Ning's army yearn for combat. Only by fighting can they make military achievements, and they will be promoted and rewarded. This high-reward system fully stimulates the initiative of soldiers. Soldiers are easy to fight. When they hear that there is a war to fight, they will be full of fighting spirit and stimulate the murderous aura in their hearts.

Cao's army took advantage of its military strength and spared no expense. Although it attacked the city wall, it still felt a little overwhelmed when facing the thick city wall that was more than 12 meters high. Although various ladders in Cao's army were set up and soldiers also attacked the city wall, the effect was not very good. They could not climb up the city wall and were wiped out by the soldiers under Hao Zhao.

When Hao Zhao saw thousands of Cao's soldiers gathered under the city wall, he immediately shouted: "Put on fuel, rocket!"

The soldiers who were specifically responsible for pouring oil on the city wall immediately poured the hot oil down the city wall. The Cao army soldiers were so hot that they cried and wiped tears by the hot oil. The sound of pain resounded through the sky. The screams made people feel frightened when they heard it.

This is not all. As the rockets of Hao Zhao's soldiers were shot out, the hot hot oil ignited a raging fire. It was not the clothes on Cao's soldiers who were on fire, but even various siege equipment such as cloud ladders burned, and the city wall instantly turned into a sea of ​​fire.

The Cao army soldiers on fire ran around, crying, screaming, and shouting; the Cao army soldiers fled back one after another, ignoring the swords and guns in the hands of the supervisor team behind them; and the Cao army could not control the retreating soldiers, and the Cao army was in chaos.

Under the burning of the raging fire, the thick smoke was pouring out dozens of feet high, and an unpleasant odor was emitted in the air, especially those who were burned to death by the fire and burned by the fire. Not only did the Cao army soldiers unable to stand the bad smell, but even the soldiers under Hao Zhao on the city wall felt uncomfortable. Many soldiers felt disgusted when they saw the meat for a long time after experiencing this battle.

After a moment of rest, Cao's soldiers continued to attack Guandu City under the supervision of the general and the command of the army; Cao's soldiers came up with various ways, but under the command of Hao Zhao, they could not attack the Cao's army, making it impossible for Cao's army to break through the city, and even the city walls could not attack, and they lost the lives of tens of thousands of soldiers in vain.

Cao's army's attacks during the day for several consecutive days did not achieve any effect, and the losses of more than 50,000 soldiers were as high as 50,000, which made Lao Cao's heart bleeding; Cao Cao knew in his heart that if there were no good methods of siege, if he continued to attack like this, he would only lose the soldiers in vain.

In the Cao army's central tent, Cao Cao's face was gloomy and glanced at his general fiercely. The strategist asked: "Everyone has any good methods to attack the city, tell me! This Guandu city is indeed not easy to attack, and I didn't expect that the defense ability would be so strong."

Xun You said: "Lord, the crossbow arrows on the wall of Lu Ning's army are too powerful. We cannot suppress the other party's crossbow arrows. If we want to successfully capture Guandu City, we must suppress the crossbow arrows on the wall. Otherwise, no matter how many soldiers attack the city, it will be difficult to succeed. Besides, the casualties are too great, and we cannot bear it."

Cao Cao said depressedly: "Gongda, you are right. The crossbow arrows in the hands of Lu Ning's army are too powerful. Who knows that the range of crossbow arrows will be farther than that of bows? The bows and arrows in the hands of our soldiers cannot resist the crossbow arrows in the hands of Lu Ning's army at all."

Liu Ye glanced at Cao Cao and said carefully: "Lord, we can also produce strong bows of more than five stones to suppress the Lu Ning army. If there are thousands of such strong bows shooting at the same time, it will cause a serious blow to the soldiers of the Lu Ning army on the city wall, and then it will be much easier for us to attack the city."

Yu Jin said: "Zi Yang, although the strong bow of Five Stones is very lethal, who can pull it? Not to mention soldiers, even if we don't have the strong bow of Five Stones."

Liu Ye said carefully: "If you can't pull it open, you can always pull it open with your feet, right?"

When Cao Cao heard this, he immediately said, "Ziyang, tell me, what's going on?"

Liu Ye said: "Lord, we produce strong bows of about five stones, and we don't need to have many accurate heads. As long as the soldiers use their feet to draw a strong bow and draw a bow in one direction at the same time, the range will definitely be far and far, which will definitely cause great harm to the soldiers on the Lu Ning army's wall."

Cao Cao listened and said, "But how can we produce so many strong bows at once?"

Liu Ye said: "Lord, I'm ready."

After hearing this, Cao Cao's face darkened, his eyes glared at Liu Ye, and said gloomyly: "Ziyang, what's going on?"

Liu Ye was shocked after hearing this. No prince wanted his subordinates to produce powerful weapons and equipment without hiding their masters. Needless to say, it is not to mention that Cao Cao is a person with a serious suspicion. If Liu Ye cannot explain clearly, then what is waiting for Liu Ye is Cao Cao's severe punishment.

Liu Ye immediately knelt down and said, "Lord, I just prepared the materials, but I have not produced them. I dare to make them without my lord's consent!"
