No doubt. The Tianshan Mountains are the tallest and longest group of mountains in the Western Regions, which divides the entire Western Regions into two parts: Southern Xinjiang and Northern Xinjiang.

In the center of southern Xinjiang is a vast desert (the Taklamakan Desert in the Tarim Basin), and in the center of northern Xinjiang is also a desert (the Gurbantunggut Desert in the Junggar Basin), and what separates these two deserts is the many clusters of mountains that run from east to west in front of the world.

In the middle of the Tianshan Mountains, there is a group of mountains that stretch out diagonally to the southeast, stretching all the way to the border of the Yanqi Kingdom, which is the Saarmin Mountain. The diagonally jutting out of the Saarmin Mountains is arranged at the top of the Harke Mountain, which is also protruding from the remnants of the Tien Shan Mountains, and between the two mountain ranges is a passage to the eastern part of the Wusun Kingdom.

Before the king of Pingxi came to the Western Regions, the army of the Wusun people traveled from here to the country and the Western Regions, and from time to time forced these small countries to pay high "protection fees" to the king of Wusun, Dakunmi. Since the Han army entered the Yanqi Kingdom, when the unknown Wusun people came out from here to make a fortune, they were beaten by the Han army very embarrassed, so they returned to their lair along the same road.

At that time, the scale of the battle was not large, it was a contact engagement, and the troops invested by both sides were only a few hundred advance reconnaissance troops. Rao is like this, and the Xiliang army at that time also taught the invincible Wusun people a hard lesson, making them feel the re-exertion of the Han cavalry since the Han Dynasty.

In March of this year, 100,000 troops under the command of King Pingxi marched westward and sent 20,000 troops to garrison between Halke Mountain and Saarmin Mountain, completely cutting off the possibility of the Wusun people invading southward. Now, the two armies are facing off in the mountains, and no one knows who will win in the end.

For thousands of years, the people of the Western Regions have been accustomed to passing between these two mountains, but some people have discovered that there is a deep canyon at the northern foot of Saarmin Mountain, which can extend from the territory of Dongwusun at the northern foot of the Tianshan Mountains to the vicinity of Yanqi at the southern foot of the Tianshan Mountains. Because this canyon is too deep and long, and there are many fierce beasts and insects and snakes in the valley, it is rarely visited all year round, except for the occasional brave herb picker and brave hunter entering.

For the Hu people, this deadly canyon is nothing in the eyes of the Shadow Members. The Shadow Officers, who have been trained and honed far beyond ordinary people's imagination, in their eyes, there are no mountains in this world that cannot be climbed, and there are no canyons that cannot be entered, because they are the eyes and ears of the Protectors everywhere and all the time.

When Zhao Xing left Yumen Pass last year, he not only called Hua Weiguo, a senior spy leader, but also took an important team member who had disappeared from people's sight for many years to go deep into the hinterland of the Western Regions.

The senior member of the Shadow team who entered the Western Regions with Zhao Xing, named Bian Xi, has been following behind Li Jinsi, the actual person in charge of the Shadow, since he joined Zhao Xing's account, as Li Jinsi's important deputy, he is mainly responsible for the daily affairs of the Shadow Headquarters.

Considering the mixed living of many ethnic groups in the Western Regions, the intertwining of forces from all sides, and the undulating terrain in the mountainous areas, Zhao Xing entrusted Bian Xi with the task of conducting careful and meticulous reconnaissance and comparison of the terrain wherever the army went, so as to prevent the occurrence of low-level mistakes that led to the failure of military operations due to unfamiliarity with the terrain and landforms. This is also Zhao Xing's professional habit as a special soldier, the so-called knowing oneself and knowing one's opponent naturally includes being familiar with and mastering the terrain.

When the Shadow Crew discovered the canyon passage at the northern foot of Saarmin Mountain, they immediately reported the major discovery to the head of the group, Bian Xi. Although Bian Xi was not a military commander, judging by his years of experience in intelligence analysis, he decided that the discovery here would definitely be the key to the use of troops by the entire team. After Bian Xi drew a topographic map of the entire canyon in detail, he taught it to Guan Yu, the governor of the capital, and as a combat officer by Guan Yu's side, Lu Xun was naturally able to see this important military topographic map.

Lu Xun in historical records, once commanded the Eastern Wu troops in the area of Yiling Yiting when he was in his forties, and defeated the hundreds of thousands of Eastern Expeditionary troops led by Liu Bei himself, and has been famous for thousands of years. Lu Xun, who followed Guan Yu, although he was still a young man less than twenty years old, his innate military talent still shone brightly at the first time.

Lu Xun suggested that Guan Yu use the 20,000 Yanqi Black Mountain Reserve Soldiers with low combat power to pretend to be the regular troops of the Xiliang Army, follow Ma Chao to the north to Jiaohe Fortress, and then ambush the replaced 20,000 Xiliang Army ace troops in the nameless valley discovered by the Shadow Members, waiting for the Wusun people to sneak attack the Yanqi base camp along this valley, so that they will be completely buried in the mountains.

This is only the first step in Lu Xun's proposal, and there is a whole set of tricks against the Wusun people behind. At that time, Guan Yu asked Lu Xun: "How does Bo Yan know that the Wusun people will definitely come from this canyon to attack Yanqi?"

Lu Xun replied: "We can find a way to take the Wusun people by the nose and send them into the Jedi in the valley!"

Guan Yu looked puzzled and motioned to Lu Xun to explain in detail. So Lu Xun proposed a plan that allowed the Wusun people to discover the clues, "Ming Xiu Plank Road Darkness Chen Cang", so that the Wusun people thought that they had seen through the Han army's plan, and then came to attack with luck.

Guan Yu asked Lu Xun again, if the Wusun people didn't know that there was such a secret canyon that could lead to Yanqi, how should they deal with it. At that time, Lu Xun replied: "If the Wusun people do not know that there is such a secret passage, then we can send troops to Wusun secretly from the canyon to Wusun and attack the Wusun people's Chigu City; ”

Lu Xun's last suggestion was to ambush a strange army in the canyon and wait for the Wusun people to come and attack. If the Wusun people did come, then this nameless canyon was the burial place of the Wusun people, and if the Wusun people were not as "smart" as they expected, and did not send troops through here, then this ambush army crossed the canyon at the end of April and attacked Akaya Castle directly.

For the Western Expeditionary Legion, it was natural to hope that the Wusun people would come to attack through the Nameless Canyon. Because in this way, not only can you make all kinds of preparations in advance with the help of the complex terrain in the canyon, and with little damage on your side, you can completely annihilate a main force of the Wusun people, but you can also quickly organize a counterattack after the victory, and directly attack the empty Red Valley Castle.

Compared to launching an ambush on the battlefield chosen by one's side, the strategy of simply sneaking into Wusun through the canyon to attack Akiti Castle was obviously a bad one, and even a last resort.

Now it seems that Lu Xun's plan is really powerful, the Wusun people are really here, and a full 40,000 people have come!

The two brothers, Ma Dai and Ma Xiu, who were ambushed at the top of the canyon, stared at the Wusun people who were passing quietly, and waited until the last warrior led the war horse to get under their crotch, Ma Dai decisively ordered: "Ignite!"

What a strange order, could it be that they are going to set fire to the mountain?
