The spies from all over the country sent a lot of intelligence, and Cao Cao was excited; Yuan Shu from Shouchun brought 200,000 troops to advance towards Lujiang; Ma Teng and Han Sui from Xiliang pulled the Qiang tribes, and the Western barbarian tribes gathered 200,000 cavalry to fight Zhao Yun's attack; Zhang Lu sent 100,000 troops to attack Chang'an; Sun Ce from Jiangdong was also ready to attack Ruxuwu Wharf without a chance; Lu Ning was not in Jinyang at this time, can he resist the attack of various armies?

Hao Zhao stood on the Guandu city wall and saw Cao's army making a huge rack. Hundreds of people were carrying it under the wooden rack and slowly moving towards the city wall. The soldiers under the wooden rack moved while cleaning up the various mechanism traps next to them. Although it was slow, there was no way to do so.

Hao Zhao ordered the catapult car to fire, but the wooden frame was still firm and could not be smashed, so he asked the sniper to clean it up. As long as the Cao army was exposed under the wooden frame, it would fire, which slowed down the Cao army's speed of cleaning the trap; the catapult car used larger stones to shoot.

Cao Jun was frightened under the wooden frame. The deafening sound above his head was like thunder. He felt that the wooden boards above him would break anywhere; however, the cowhide on the wooden frame was indeed useful, otherwise he would have been smashed by a catapult.

Cao's army took two hours to clear out the last nearly 200 meters of road. Although it was not very spacious, it could barely bear Cao's large-scale attack channel.

The catapult cart on the city wall used larger stones and successfully smashed the terrifyingly large and bulky wooden frame. Hundreds of Cao soldiers under the wooden frame were immediately attacked by crossbow arrows, and all hung up in just a moment.

Cao Cao was very satisfied. Although he had lost many soldiers, he might have successfully opened up the passage of advance, which was a clear obstacle for the large-scale attack in the afternoon.

Liu Ye is indeed not simple. He not only produces weapons and equipment such as thunder chariots, but also produces siege equipment such as Mu Man; especially the Mu Man is indeed a powerful weapon for siege, but it has no attack power. It just uses a special wooden board to ward the flint, which can withstand the firestone bows and arrows. There are more than a dozen archers hidden behind it. As long as you reach an appropriate distance, you can shoot arrows from Mu Man to the head of the city to cover up other people's attacks. The stormtroopers hide behind Mu Man and can also come to the city without any casualties, greatly reducing the casualties required for siege.

Cao's army braved huge casualties to clear out the passage to the Guandu city wall, and then the ant-like Cao army landslides the moat. Although there were heavy casualties, Cao Cao seemed to have to take Guandu at any cost.

Standing on the city wall, Hao Zhao saw Cao's soldiers swarming up and immediately ordered a catapult cart, and crossbow archers opened fire; instantly, raindrops pressed into Cao's formation; due to the short distance, the crossbow beds were shot with three arrows, five arrows and ten arrows at a time. On the powerful crossbow, rockets pierced into wooden curtains, wooden boards, cloud ladders and other siege equipment. With the powerful power of the crossbow bed, Cao's siege equipment burned one after another.

The fierce crossbow arrows fired from the crossbow bed have great lethality to the shields in the hands of Cao's shield soldiers and can directly penetrate the shields. Without the shields, the Cao's soldiers covered by the wooden curtains faced the shooting of the crossbows on the city walls directly.

Under the attack of raindrops, Cao's soldiers shouted, screamed, moaned, and cried, and various arrows sneered above the heads of Cao's soldiers. Although Cao's archers entered the range, they fell down under the powerful rain of Hao Zhao's arrows. Even if Cao's archers shot, they would not cause much damage to the soldiers of Lu Ning's soldiers on the city wall.

The soldiers of the Lu Ning army all have excellent armor and helmet protection, and all key parts are protected. Their defense ability is not only the arrows of Cao army archers, but even if they are directly killed with swords and guns, it is difficult to achieve results. At most, they will have some minor injuries.

Lu Ning is a time traveler and has always paid great attention to the research and development of weapons and equipment. In Lu Ning's dictionary, he always believes that war is money and technology. Especially in the era of cold weapons, the quality of weapons and equipment directly affects the strength of soldiers' combat effectiveness and the level of casualties of soldiers.

Cao Cao was behind, watching the soldiers falling down in pieces, as if they were bleeding in their hearts. What made Cao Cao very depressed was that the range of the crossbows in the hands of the Lu Ning soldiers on the city wall was farther than that of the bow and arrow, which made Cao Cao and his generals very confused. In the eyes of Cao Cao and others, they all thought that the range of the crossbows should be less than that of the bow and arrow, but the crossbows in the hands of the Lu Ning soldiers really caused Cao's army to suffer a great loss.

Cao Hong said: "Why are the crossbow arrows of the soldiers under Big Bear so powerful? It seems that the range is even further than the bow arrows in our soldiers?"

None of the generals could explain Cao Cao's advice to the border. Everyone looked at Xun You, hoping that Xun You would explain it; because only Xun You's uncle and nephew had been to Lu Ning's jurisdiction.

Xun You smiled bitterly and said, "Lord, I have only seen it in Jincheng, but I don't know that the range of crossbow arrows will be so far; this crossbow is a banned product of Lu Ningjun and will not be sold to anyone."

Cao Cao shook his head and said, "The crossbows in the hands of the soldiers under Lu Ning are too powerful. They only have three arrows and five arrows at one time, and the shooting speed is very fast. It's such a powerful weapon!"

Xun You saw that in just two hours, nearly 10,000 soldiers of Cao's army fell down, and he didn't even find the city wall. The moat was not filled with soil, but with the bodies of Cao's soldiers. If you continue to attack like this, there will be no effect at all, and it will only leave the soldiers' lives in vain.

Xun You said: "Lord, let's withdraw your troops!"

Cao Cao had no choice but to attack the left, middle and right armies, but did not have much impact on Lu Ning's army, and his soldiers were indeed suffering heavy casualties; he just called the gold to withdraw his troops.

Back at the central army's tent, Cao Cao said: "Everyone said that the crossbow arrows of Lu Ning's army are too powerful and their lethality is unexpected. What can we do to suppress them?"

Everyone knew in their hearts that if they did not suppress the soldiers of Lu Jun on the city wall, they would all hang up on the way, let alone attacking the city wall, and the dense rain of arrows would be too powerful.

The arrows and arrows of Lu Ningjun were all triangular, with small blood grooves on three sides, which greatly improved the lethality. This was definitely an innovation in the Three Kingdoms period. The power of arrows with blood grooves and without blood grooves is different. Arrows without blood grooves will have much less lethality, while arrows with blood grooves can effectively shoot and have powerful power. This is basically known to later generations, but they were different in ancient times. With such a little difference, their power is completely two.

Cao Hong said foolishly: "Lord, let's cut off the water source of Guandu."

Cao Cao shook his head and said, "Guandu is facing the Yellow River, and there is a lot of water. How can this be broken?"

Cao Hong smiled awkwardly and knew he was talking nonsense.

Xu You said: "Lord, let's dig a hole? As long as you can dig the hole into Guandu City, you can launch a surprise attack."

Dong Zhao shook his head and said, "The moat in Guandu is so deep, how can you dig a hole? If it is shallow, it will be fully exposed in the Suocheng River. If it is to dig deep, it will be too time-consuming and easy to be discovered by Lu Ningjun; it can only be excavated under powerful attacks, but the casualties will be even greater."
