The area west of Jiangyou is almost all steep mountains, here is the remnant vein of Zuodan Mountain, you can't go out of one or two miles into the mountain, the valley that was still wide before suddenly narrows, the mountain peak wall that is straight like a knife is ten thousand miles, and the road that can be passed between the mountainside is also left with the sheep intestine trail.

The Yinping Trail is hidden in the vast mountains, and if you can't know exactly Deng Ai's marching route, it will be meaningless for Liu Yin to enter this lofty mountain. Because Liu Yin couldn't know that Deng Ai would go out of the road to Jiangyou, because in this group of mountains, there is no so-called road at all.

Therefore, Ah Jian's reconnaissance operation is particularly important, to a small extent, it is directly related to the success or failure of this Yinping resistance battle, and to a large extent, it determines the fate of the survival of Shu Han.

A Jian and his entourage entered the mountainous area in the northwest of Jiangyou as early as ten days ago, and in the face of the vast mountains that are deserted, A Jian and his party of more than a dozen people are like a drop in the ocean, small to the extreme, trying to find out the whereabouts of the Wei army in this group of mountains, and try to climb to the sky.

Ah Jian was very anxious, seeing that time was passing day by day, they had wandered around hundreds of miles in the deep mountains, searching for a lot of places, but it was like looking for a needle in a haystack, and no trace of the Wei army had been found so far, which made Ah Jian very worried.

Although Liu Yin provided him with a rough map, but when he really walked into the mountains, Ah Jian found that those maps were not much different from nothing, and they were rough and not at all, except for a general direction, Ah Jian could no longer find any useful information from the map.

Just when Ah Jian was in despair, he unexpectedly met several Qiang people who were hunting in this mountain forest. Shu Han officials classified this area as a no-man's land because there is no registered population in this area, and these Qiang people are not the people of Shu Han at all, but they do live in this mountain.

Ah Jian was originally a descendant of the Qiang people, and he could speak the Qiang language, so he had no difficulty communicating with these hunters. From the mouths of these hunters, Ah Jian finally learned about the movements of the Wei army.

Deng Ai commanded an army of 30,000, and it was almost impossible for him to quietly and secretly march, these hunters living in the mountains had already discovered their existence, but the Qiang hunters, who had never been in contact with the outside world, regarded such a huge army as a flood and beast, and avoided it, and wherever the Wei army went, they would flee far away.

Ah Jian was like a treasure, using these hunters as guides, Ah Jian finally saw Deng Ai's army coming over the mountains and rivers, but even if Ah Jian was strong, he could only see the news of the Wei army from a few miles away, and he didn't dare to get too close at all.

After Ah Jian grasped the first-hand information of the Wei army, he quickly returned to Jiangyou. Before he arrived at Jiangyou, he met Liu Yin, who had already led the army, at the Qingdao crossing.

Liu Yin didn't dare to delay much in Jiangyou at all, and simply dealt with the matter after the improvement, and Liu Yin led the army to leave Jiangyou at the fourth watch of the next day.

After Ma Miao and his henchmen were wiped out, the entire Jiangyou garrison has basically become a plate of scattered sand, and now the highest rank in the army is left with the two Dubo who took the initiative to stand up that day, and before the imperial court sent a new guard, the entire Jiangyou garrison was basically paralyzed.

This is something that Liu Yin can't tolerate, the defense of Jiangyou Pass is not trivial, even if he goes to Yinping Trail to block Deng Ai, it is difficult to predict whether he will succeed, and Jiangyou Pass is undoubtedly a retreat for Liu Yin, if he can't keep the Yinping Trail, he must retreat to Jiangyou Pass.

At this time, the state of the Jiangyou defenders was not enough to fight a hard defensive battle, if Jiangyou was abandoned at this time, Liu Yinzhen did not know what would happen to Jiangyou Pass.

Therefore, Liu Yin left Fu Zhi and Fu Zhao at Jiangyou Pass, and let them be responsible for commanding this garrison. Those forces loyal to Ma Miao have been purged, and now among the Jiangyou defenders, there is no longer the force that dares to commit treason, although Fu Zhu and Fu Zhao have no experience in leading the army, but they are also the sons of Jiangmen, under the influence of Fu Yan's ears and eyes, they also know more about how to govern the army.

What's more, Liu Yin's subordinates really don't have any other manpower, Zhang Le and Zhao Zhuo, the two fierce generals, are the main force in the confrontation with Deng Ai, and they can be called Liu Yin's right-hand man, and it is difficult to fight without one.

Fortunately, before the fall of Yinping Xiaodao, Jiangyou Pass was still safe for the time being, and Fu Zhu and Fu Zhao's responsibility was to manage the defenders of Jiangyou, strengthen the defense of Jiangyou Pass, and provide logistical support for Liu Yin's army on the front line.

Fu Zhi and Fu Zhao were obviously unhappy, they followed Liu Yin to the front line this time, just to be able to fight, but seeing that they were about to fight with the Wei soldiers, Liu Yin wanted to leave them at Jiangyou Pass, which was far from their original intention.

"Brother-in-law, let someone else guard the Jiangyou Pass, let our brothers go with you to fight Deng Ai!"

Fu Zhao and Liu Yin were soft and hard, forcing Liu Yin to stare at them and reprimand them a few words, and then quietly remained silent.

The importance of Jiangyou Pass is self-evident, if Liu Yin does not pay attention to his confidants to guard Jiangyou, he is really not at ease.

Leaving Jiangyou, Liu Yin marched along the river valley towards the Qingchuan Pass.

When Ah Jian left, he left marks along the way, and Liu Yin only needed to follow the marks.

Just out of more than ten miles, the mountain rises abruptly, the road full of thorns becomes narrow and steep, the towering peaks, the straight cliffs, people are daunting, the winding sheep intestine path can only accommodate one person, and the horses and vehicles can not move forward at all.

Liu Yin could only camp at Qingchuankou, leaving his horses and vehicles in the camp, and all the private soldiers marched on foot, each carrying three days' dry rations, and carrying wooden boxes full of gunpowder arrows and bamboo bombs on their shoulders, ready to advance.

If it was possible, Liu Yin would definitely set up the base camp relatively close to the blocking position, but the road ahead was too difficult and dangerous for horses and vehicles to pass through at all, so this base camp could only be set up at Qingchuankou, leaving a special person to guard it.

As for the position of the blockade, Liu Yin has not yet been determined, and he can only make a final decision after contacting Ah Jian.

Liu Yin's luck was not ordinarily good, as soon as he finished camping, Ah Jian appeared like a gust of wind.
