When the Wei army first attacked the mountain, it adopted a bunker tactic. Every time it advanced for a distance, it dug out some large pits on the road ahead and built high barriers, so that the Wei army that followed it had a hiding place.

The defensive weapons of the Shu army, such as bows and arrows and rolling wood and stones, will not turn around. At most, bows and arrows can shoot a parabola. As long as the Wei soldiers are hidden behind the cover, they can avoid the attack of the Shu army.

Of course, this just-starting mountaineering road is still outside the range of the Shu army's bow and arrows. The Weirongpo is just three or four miles long. No matter how far the Shu army's bow and arrows are, it is impossible to shoot from the top of the mountain to the foot of the mountain.

But it is possible to roll wood and rocks. Because the slope of Weirong Slope is very steep, the Shu army can use roll wood or rocks to attack the Wei army. Therefore, the Wei army dug up bunkers fortifications from the beginning of attacking the mountain. The main purpose is to prevent the attack of rolling wood and rocks.

The slope of Weirong Slope is very steep, and many areas may even have slopes of more than fifty degrees. When building roads, such a slope cannot directly lead the road to the top of the mountain. He had to use a tortuous and twisty way to build a winding mountain road. When the Wei army attacked, he could only advance along this winding mountain road to the mountain.

When defending, the Shu army was condescending and occupied a unique geographical advantage. Even if the bows and arrows were not used at this time, they were prepared for a lot of rolling wood and beating stones. On such a steep slope, throwing a few stones and wood would be enough to cause great harm to the Wei army.

Shi Bao's step-by-step advancement and bunker tactics can avoid this risk. Whether it is rolling a wood or pounding a stone, as long as it takes action, its trajectory is uncontrollable and will change due to whether there are obstacles in the rolling path.

Of course, the Shu army hoped that the fewer obstacles, the better. When they built a mountain village, they would clear out all the trees or huge rocks on the hillside, so as to make the front as possible without any obstacles.

The Wei army, on the other hand, wanted to do the opposite and create as many obstacles as possible on the road as possible to destroy the attacks of the Shu army's long-range weapons.

Liu Jing used this method in the Battle of the Bingting and achieved good results. It is indeed effective against the heavy weapons that are freely falling, such as those of free-falling, and can greatly reduce the damage caused by the rolling wood stone.

In fact, the most difficult thing to attack a steep and important village like Weirong Village is the number of hillsides. The attacking troops are almost unblocked when climbing to the top of the mountain. The defenders can use everything they can use to attack the attacking troops.

Most of the copycats have the most limited resources of wood and stone, which can be said to be inexhaustible and inexhaustible. The defenders do not need to consider the issue of reserves, and they can squander it unscrupulously.

Therefore, attacking a parraid is completely different from siege. The Wei army has indeed accumulated a lot of experience in siege. The use of catapults alone is enough to make any city defender drink a pot.

However, due to the range of attacks, the catapult car has no purpose at all. If you just use the human sea tactics to attack, the casualty rate will be a heavy burden that the Wei army cannot bear.

The tactic of slow advancing of bunker tactics is currently the best tactic for attacking mountains. Although it has the problems of slow attack speed and poor efficiency, it has miraculous effects in reducing casualties.

And this effect is exactly what Shi Bao pursues. As long as the soldiers' casualties can be minimized, it doesn't matter even if the speed of advancement is slower.

Don’t be afraid of being slow, just being afraid of standing. As long as the Wei army can advance forward every day, even if it is only a few feet away, it will not be difficult to capture the Shu army’s position every day.

In order to prevent the counterattack and destruction of the Shu army, the Wei army arranged a large number of crossbow soldiers to enter the tunnel during the bunker advancement. As long as the Shu army dared to attack, the Wei army would use crossbows to fight back, so that the Shu army would not dare to approach at all.

The Bu Xie was also a headache for the new tactics adopted by the Wei army. During the process of advancing up the mountain, the Wei army dug a lot of bunkers along the way, and these bunkers had high bases and tunnels, which greatly reduced the attack effect of the Shu army rolling wood and rocks.

Although the rolling wooden rocks look amazing, they can only produce the damage effect they deserve if they hit the place where they should hit. Otherwise, even if they hit someone, what will it do if they are powerful?

When Bu Xie was deploying the defense, he had already considered this issue as much as possible. The hillside of the turquoise slope was originally covered with lush vegetation, tall trees, low shrubs, large stones everywhere, and uneven terrain, with many obstacles everywhere.

The BFA sent troops to carry out a large cleanup, cut down all the trees, removed all the big stones, flattened the high terrain, and set fire to the mountains, burning all the dense forests in the Weirongpo area, becoming a barren mountain.

Bu Xie did not allow him to have any obstruction within his sight on the top of the mountain. If he allowed the existence of those jungles, wouldn’t he provide natural protection for the Wei army? The Wei army had attacked under his nose and the Shu army could not find it.

Therefore, when clearing Weirongpo, the Shu army still spent a lot of effort. Bu Xie stood in Weirong Village and looked down and saw that he could see everything. He was very satisfied with this effect. It was unobstructed. No matter how the Wei army had any actions, it would be impossible to hide it from him.

The steep hillside of Weirong Slope is the best place to use for wood-rolling stones, especially the thick rolling wood, after rolling down from the top of the mountain, the power of sweeping thousands of troops is not something human power can stop it. Bu Xie believes that only by throwing some wood-rolling stones on his side can he beat the Wei army to fall and flow all over the ground. No matter how strong the Wei army is, they are still flesh and blood. Bu Xie does not believe that they can withstand this thunder critical strike, and any army can only be crushed.

Just as the Bus Association was full of confidence in its defensive position, the Wei army launched an attack.

Everything was beyond Bu Xie's expectations. The Wei army's attack did not show such a scene of crowds of people like locusts and ants. Instead, it was advancing very slowly. From a distance, it looked like snails climbing there, so slowly that they gave in to Bu Xie's urge to beat people.

The Wei army not only had speed like snails, but also had the way of advancing like mice drilling into the ground, constantly digging trenches and holes, digging the inclined flat ramps that the Shu army finally cleared out was devastated and uneven.
