The heavy fog made Yang Hu unable to see the scene in the distance, nor could he understand the defense situation of the Shu army at Sanguan, which undoubtedly increased the difficulty of the Wei army's attack.

However, everything has its own two sides, and the thick fog also provided cover for the Wei army. At this moment, the Shu army in Sanguan did not realize that a Wei army was approaching them a few miles away from them.

So Yang Hu decided to take advantage of the fog that had not yet dissipated and sent a suicide squad to attack. If the Shu army was caught off guard, it would be best if it could be defeated. If it could not be taken down, it would also cause some trouble for them and provide convenience for subsequent attacks.

So Yang Hu sent Qu Ling, the former military captain of the infantry battalion, to lead a suicide squad composed of five hundred talented men who were carefully selected and came out of distance, and took advantage of the heavy fog to touch the direction of Sanguan.

The three-mile journey was not close or far. Qu Ling quickly led his troops to touch it. After approaching Sanguan, there was a valley. The fog in the valley was even thicker, and there were no figures of people a few dozen steps away. Under the leadership of the guide, the suicide squad slowly approached Sanguan. They moved quietly along the way without making any sound.

When approaching the Shu army's post, Qu Ling sent several soldiers with high martial arts skills to launch a raid, killing the soldiers on the post with one blow. The Shu soldiers didn't even have a chance to shout, and were tragically cut by the Wei soldiers.

After successfully resolving the outer checkpoints, the Wei army had already touched the front of the Shu army's position, but the Shu army was even cautious. When setting up the Minggang, it still arranged secret sentries in secret places. The Wei army could discover the Minggang of the Shu army, but it was powerless to do anything about the secret sentries.

When the people in the secret whistle found that the Wei army was infiltrating, they immediately rang a clamor to warn. The crisp sound of the clamor seemed particularly loud in the quiet morning mist.

"The enemy attacked—" Someone was shouting on the Shu army's position, and the sound in front immediately became noisy. Then, the sound of arrows breaking through the air came, "Swoosh swish", dense arrows shot out from the thick fog, and the Wei soldiers who rushed in the front were caught off guard and fell to the ground.

Qu Ling shouted: "Look down! Cover!"

He saw that the Shu army used the Yuanrong crossbow as soon as it was launched. This kind of crossbow had an astonishing lethality and a huge coverage. The terrain on it was very narrow. If the Wei army forcibly broke through, it would only increase casualties.

Obviously, the Shu army had already taken measures to deal with the Wei army's sneak attacks and deployed the most elite crossbow soldiers at the forefront of the position. Once the Wei army approached the defense line, they would use crossbows to attack without hesitation.

At this moment, the fog was covered, and the Shu army could not see how many Wei troops came to attack. When they heard the sound of warning whistles, they did not hesitate to attack the Yuanrong crossbow, blocking the roads in front of the mountain with bows and arrows, and not giving the Wei army any chance to attack.

The Shu army was extremely smart. After all, in the fog, it was impossible to tell how many troops the enemy had to attack. Once the enemy was brought closer to the position, the consequences would be unimaginable. The wisest choice was to use a crossbow to conduct long-range attacks and prevent the enemy from getting close to each other.

At most, it would be a waste of arrows, but the Wei army had no chance to rush up. If they forced themselves to rush, they would have to be shot into a hedgehog by arrows.

Qu Ling and others hid in a hidden place, with arrows roaring past their heads, and they had no chance to raid at all. They had no choice but to retreat temporarily and report to Yang Hu about the situation of the Shu army.

Yang Hu couldn't help frowning slightly. Logically speaking, the Wei army's actions were very secretive. It was the early morning when the enemy was most negligent in preventing the attack. Moreover, the heavy fog from the sky also added a layer of cover for the Wei army's attack. However, I didn't expect that the Shu army's defense was so strict that they did not give them any chance to attack. It seemed that there were indeed capable people in the Shu army, and their defense was done without any leakage. This time, his sneak attack would probably be ineffective.

However, Yang Hu was not willing to retreat so easily. When the sun rose and the fog dissipated, Yang Hu was preparing to launch a powerful attack. Although he did not bring all the troops from the two infantry battalions, he also brought at least 20,000 light armor, and he had to fight for it no matter what.

The sun rose and still could not move away from the severe cold of winter, but the fog gradually dissipated, and the appearance of Sanguan ahead gradually appeared.

Strictly speaking, Sanguan is no longer a Guancheng, with only a few broken Guancheng walls, and even the Guancheng Tower has collapsed halfway, which is extremely broken.

Since Sanguan is located deep in the mountains and has difficulty in logistics supply, Guo Huai did not re-enter the Sanguan when building the Guanlong defense line, but instead built Chencang City on a large scale. Therefore, after several war ravages, Sanguan has long been abandoned.

The defensive positions built by the Shu army at Sanguan were not entirely based on Guancheng, but seized the commanding heights around Sanguan and built the outer positions. If the Wei army wanted to seize the Sanguan, they had to take down these outer positions first.

But Yang Hu looked at these defensive positions and relied on each other. Unless the Wei army annihilated all the Shu troops defending the positions, even if they took down several positions, it would be useless.

The Shu army occupied all the favorable terrain, and the Wei army was in a position of attacking the enemy. The difficulty of this kind of attack was very high. Yang Hu tried several attacks and encountered failure without exception.

The main problem is the terrain limitation. Although the Wei army had 20,000 troops, it could not be carried out on this narrow mountain road. It could only send a small number of troops to launch an attack. However, the Shu army arranged a large number of crossbow soldiers on the defense line, which easily blocked the road, and it was difficult for the Wei army to attack.

Although there were not many Shu troops defending Sanguan, only a few thousand people, due to the limitations of the terrain and the perfect formation of the Shu army, the Wei army had no opportunity to take advantage of. If the Wei army forcibly attacked, it would only increase casualties. Yang Hu could only sigh lightly. Just as he was about to order his evacuation, he suddenly discovered a familiar figure in the Shu army's position.

Yang Hu suspected that he had read it wrong, so he immediately rubbed his eyes and looked closely. Yes, that person was his father-in-law Xiahou Ba. Although he hadn't seen him for more than ten years, Yang Hu still recognized him at a glance.

Unexpectedly, the opponent was his father-in-law. Yang Hu suddenly had an idea when he was ridiculous and cried. If he could not attack him, he could only be a clever one. If he could convince Xiahou Ba to return to Wei, wouldn’t Sanguan be at his fingertips?
