God also cooperated extremely. Liu Jing waited for three days and waited for a heavy fog all over the sky. This time the fog was thicker and thicker than the fog four days ago. The white fog was like a veil, covering people's eyes. Many people raised their hands and could see the fog lingering on their fingertips. They stretched out their arms, and their five fingers became vague. Looking forward, they could see nothing except the white area.

Liu Jing was overjoyed. It was really God’s help, and it was hard for him to fail.

In the past few days, the Wei army has been preparing for an offensive, including gathering troops, preparing for war, road surveys, and logistics supplies. It can be said that everything is ready, just waiting for heavy fog.

Now that the fog is coming, the Wei army has already made sufficient preparations. Liu Jing also knows that the time they can use is actually very short. Once the sun rises, the fog will dissipate. Even if the rainy weather is maintained, the thick fog will not last long. Once the visibility increases, the protective effect of the fog will be lost. Therefore, if the Wei army wants to launch an attack, it must seize this window period. It cannot eat the entire Guiniupo position in one bite, but at least it can also destroy some of the outer strongholds of the Shu army and create opportunities for the Wei army's subsequent attack.

With the successful experience of the Eagle-billed Cliff Mist Battle, Liu Jing was full of confidence in attacking Guiniupo this time. In view of the many attack routes of Guiniupo, Liu Jing arranged multiple troops to launch an attack to achieve the effect of not illuminating the east and the west.

The Shu army was completely unprepared at Yingzui Cliff and suffered a great loss from the fog battle. I believe Sima Lun would not sit still and wait for death. He would definitely strengthen the countermeasures.

However, for the defensive side, it is almost impossible to eliminate the impact of the fog. After all, it is heavy and it is difficult for the Shu army to find the Wei army that is approaching quietly. Even if they are ready to take a twelve-point spirit and be on guard, they often find that after the Wei army attacks, the Wei army has reached their noses.

If the narrow advantage of the geographical advantage cannot be used, the battle between the two sides will be in a balanced state.

Under the same conditions, the Wei army was not afraid of the Shu army at all. At this point, Liu Jing was still fully confident, especially the Sima army and the Wu army. Although they are now included in the battle sequence of the Shu army, they are not equipped with the Zhuge crossbows of the Shu army. Compared with the Wei army, they do not have much melee advantage in comparison with the Wei army. The Wei army has strong firepower support such as the crossbows, which obviously has the upper hand.

In the Battle of Eagle-billed Cliff, the cover of heavy fog is certainly the biggest reliance on victory, but when launching a close-range attack, it would be difficult for the Wei army to control the situation without a close-range strong firepower suppression weapon like a repeating crossbow. Therefore, the real magic weapon to win this battle is still a powerful repeating crossbow. It was the Wei army who used the repeating crossbow to suppress the Shu army on the defensive position and took advantage of the situation to take down the Eagle-billed Cliff in one go.

Therefore, when this time the attack on Guiniupo, the crossbow soldiers were still the backbone who rushed to the front line. Liu Jing wanted to use the powerful attack power of the crossbow square formation to tear open the defense line of the Shu army.

If the Battle of Eagle-billed Cliff was a surprise attack, and it was a surprise, then this attack would not have had such an effect again. Faced with the well-prepared Shu army, the Wei army had no choice but to attack one way.

The heavy fog was a signal of attack. Liu Jing immediately issued an order to attack the Wei army, who was waiting for the battle. According to the original plan, all the troops launched a comprehensive attack on the Guiniupo position of the Shu army.

Since the Wei army had already stepped on the attack route in advance, even if it was foggy now, it was difficult to identify people outside five steps, but the Wei army could still launch an attack through the established route.

What's more, all battalions, divisions and quns of the Wei army were equipped with tools such as compass, so the Wei army had a considerable advantage in distinguishing directions.

Although there was Sinan in ancient times, Sinan was expensive and inconvenient to carry, so few people use it.

Although Ma Jun built a guide car, it was just a tribute dedicated to Emperor Ming and was not widely used in the army. Although the guide car built by Ma Jun made Emperor Ming and the ministers curious, after the freshness, the guide car was sealed in the corner of the palace warehouse and no one was interested in it anymore.

Although Cao Liang had obtained the drawings of Ma Jun's compass, this thing was like a useless person to Cao Liang, so Cao Liang was too lazy to imitate it. After all, the compass was complex in structure and huge in size. Cao Liang could make a small and flexible compass. Isn't it fragrant?

In later generations, the compass was a very simple thing. As long as you understand its production principle, it would be easy to make it. Therefore, Cao Liang would not consider copying Ma Jun's compass with complex structure. Cao Liang's goal was to make a small compass that is easy to carry and use so that it can be used by individual soldiers.

The compass is very practical to distinguish directions in rainy and foggy days. It is precisely because the Wei army is equipped with a large number of compass, so Liu Jing does not have to worry that the Wei army will get lost at all.

The most important thing to march in the fog is to keep silent and make as little noise as possible. After all, in the fog, vision is completely ineffective, and the range you can see is only a few steps and a dozen steps away. Today's fog is indeed large enough. When attacking the Hawkeye Cliff a few days ago, the fog was not so thick.

However, the thicker the fog, the more beneficial it is to the Wei army. Although the Shu army is prepared for it, they cannot prevent the Wei army from approaching anyway. It is like knowing that the enemy is right in front of them but they cannot see it. This will undoubtedly make the Shu army more anxious and impatient.

Although the Wei army launched multiple attacks this time, the offensive strategy adopted was still almost exactly the same as the last attack on the Eagle-billed Cliff. It was to use the cover of heavy fog to quietly approach the Shu army's defensive position, and at close range, use the powerful firepower of the crossbow to suppress the target, and then the infantry launched a comprehensive assault, taking down the Shu army's position in one fell swoop.

Because it is uncertain when the fog will dissipate, the Wei army's attack must be fast and effective, and the frontier targets of the Shu army that have been locked must be taken down as soon as possible. Otherwise, once the fog dissipates, the Wei army, which has not had time to take down the Shu army's positions, will inevitably be exposed to the bows and arrows of the Shu army.

Without the cover of heavy fog, the Wei army, which was stranded on the battlefield without the dangerous terrain, would become dangerous, so the Wei army's attack could not be delayed for a moment.
