After nightfall, the moon hangs in the air, the peaks of the Yin Mountain area towering between the canyons, under the reflection of the moonlight, show bright or dark spots, in the hazy night, the surface is shaped into different shapes, which makes people feel a little hideous.

The night is already deep, the rolling Yinshan mountain system is quiet, because it is still early spring, the beasts and birds do not come out at this time to move much, occasionally can only hear one or two neighs of some birds or other animals, breaking the silence of the night, echoing in the valley, making people listen to some cowardice, but soon be covered by the boundless silence, as if it is just a human illusion.

In a fence in the middle of the Baidao, a north-south passage connecting Yinshan Mountain, hundreds of Turks stationed here are ready to rest after a full meal of wine and meat in the evening.

The white road between the yin mountains, the width of different sections is very different, there are hundreds of steps at the widest point, which can be camped by thousands of soldiers, and there are only two or three steps at the narrowest point, and there are towering peaks and flowing streams and rivers on the side, there is a great tendency for a man to be the pass, and this place where the Turks sent troops to guard is the most dangerous section in the white road. However, the Turks have not been guarding here, many times there is no one to guard the Baidao, this time it was after Ashina Funian met with several tribes to rebel against the Tang Dynasty, in order to prevent the Tang army from attacking the tooth tent they set up, and built a fence in the most dangerous place of the Baidao, and sent a certain number of soldiers to guard it.

At the beginning of the rebellion, they sent troops to garrison this most dangerous place in the main road from Yinshan to the desert, but because of the influence of the terrain and environment, although this place is very dangerous and important, it is impossible to send more sergeants to garrison, five hundred sergeants are already the limit, no more can stay, and when there is a war, there are only about a hundred people who can fight the enemy head-on, If all the men were on the field, they would not be able to spread out in the front, but in the same way, the enemy troops from the north and south could not concentrate a large number of troops to attack the camp.

According to the news that came, the Tang army was galloping towards the Yinshan area from all sides, and Ashina Funian, who was embraced as the khan, knew that his strength was still at a disadvantage compared with the expeditionary Tang army, and in addition, there were Hui and Qibi troops in the north and northwest to echo the orders of the Tang Dynasty and prepare to attack them together. In the case of the different marching speeds of the various units of the Tang Army, they were prepared to take the method of splitting up the Tang Army, striking first and launching a preemptive attack on the Tang Army coming from afar, and striving to force the Tang Army not to dare to approach the Yinshan area with the victory of several battles.

Therefore, Ashina Funian and Ashdevin Fu each led 30,000 horses to attack in the northwest and southeast directions from the north and northeast of Yinshan, preparing to attack the Tang army coming from the direction of Fengzhou and Youzhou, and taking advantage of the superiority of their own numbers within a certain range to annihilate the Tang army in these two directions.

Ashina Fu attacked from the eastern direction of Yinshan Mountain, Ashina Fu Nian led the troops from Baidao, and they set off for many days, and Ashina Fu Nian left from Baidao for two days, because his Khan led his troops to attack the Tang army, and the Turks who stayed in the Baidao gate to guard almost never thought that the Tang army might attack them at this time, so they were also at ease to rest.

And just as these well-fed Turks were preparing to rest, on the east side of this fence built of wood by taking advantage of the terrain, hundreds of heavily armed sergeants were touching this fence from a secret passage halfway up the mountain, not even a passage, but a relatively gentle hillside.

These were 300 carefully selected Tang army sergeants led by Liu Yi himself, ready to attack this stronghold guarded by the Turks at night.

Participating in the operation were the remaining guards around Liu Yi, as well as the two generals Jing Hui and Huan Yanfan, and the other sergeants were the best and most skilled fighters in the army, Liu Yi just hoped to uproot this stronghold when the Turks were defenseless.

Liu Yi felt that only he could be competent to command, he was an expert in secret operations, and he had carefully observed the mountains around Yinshan before the operation, the mountains in the north had a similar place, the vegetation on the mountains was very sparse, and there were not many shrubs and other low plants, which should be the reason for the lack of precipitation, except for some larger trees, the mountains were relatively bare, even if it was a lurking march at night, there would not be too much trouble.

Before setting out, Liu Yi ordered Zhang Qianqiao to take command of the remaining sergeants, and immediately after he led his troops to succeed, he led the sergeants through this stronghold, and passed through Baidao as quickly as possible to the north of Yinshan.

In this warm-up battle before launching an attack on the Turkic tooth tent, Liu Yi's goal was to try not to escape a single Turk, and to wipe out all the Turks guarding this stronghold.

Liu Yi knew that his unit was only more than 6,000 people, and he was at a numerical disadvantage compared to the Turks, and if he wanted to win with one blow, he had to be skillful, and he could not fight the Turks head-on.

In the art of war written by Li Jing, what is most talked about is to attack the enemy by surprise and concentrate forces to cover up and kill while the enemy is unprepared, which is the attack method that the side pays the least price, and only when it is unavoidable, does it choose to fight the enemy head-on. If you fight head-on, even if you can achieve victory, the price you pay is very large, the so-called killing a thousand enemies, self-damage of eight hundred is this principle, Liu Yi, who has been engaged in secret operations in later generations, likes the sneak attack battle the most.

Liu Yi led these sergeants to the halfway point of the mountain not far from the Turkic fence after half an hour of lurking march, and Liu Yi issued an order to order the sergeants under his command to rest temporarily, recover their strength, and wait for orders. After all the sergeants rested silently, Liu Yi went up to a stone, raised his binoculars and looked at the fence below, except for the sporadic lights, no figure could be seen.

There were only a few hundred paces away, and the Turks did not make any movement, and they must have not discovered our whereabouts, Liu Yi calmly ordered, according to the plan arranged before the battle, with a team of 100 people, ready to rush to the Turks' stockade from several directions.

From this direction, you can feel the village, it was a few guards sent by Liu Yi in advance, that is, the guards who were waiting for Liu Yi at the mouth of the canyon, and they took these hundreds of Tang Army soldiers to use the cover of night to touch under the noses of the Turks.

These well-fed Turks never dreamed that a catastrophe would befall them on such an ordinary night, and these Turks remained as usual, leaving only about 20 people to be on duty outside, and most of them were resting in the houses built by taking advantage of the mountain.

After the 20 or so people on duty stayed idle for a while, most of them also sat on the ground with scimitars in their arms, wrapped their robes tightly, and prepared to take a nap.

Just when these Turks were sleeping or half-asleep, several black shadows quietly climbed up through ropes from under the walled wall more than a few meters high, and almost without any sound, they landed on the wall, and when several Turkic people with slightly higher vigilant surnames just reacted and were about to ask, the quick knife in the black shadow's hand had already cut their throats.

These are the thirty guards that Liu Yi brought, and the best ones among the guards left, they have learned most of these methods of Liu Yi's assassination, although they have not learned the essence of Liu Yi, but it is more than enough to deal with these defenseless Turks.

Liu Yi, who had a glint in his eyes, immediately sent a signal to his companions after he succeeded, preparing for follow-up actions, and the guards who followed Liu Yi also immediately went to twist the suspended bridge that was suspended high and put down the suspension bridge that blocked the passage of the white road. Almost a moment after Liu Yi gave the signal, the sergeants led by Jing Hui and Huan Yanfan, as well as the remaining personal guards of Liu Yi led by Liu Quan, all rushed into the houses where the Turks lived from their respective lurking positions.

After storming into the house, some lit a fire to illuminate the room, while other sergeants took advantage of the light of the fire to cut down the Turks who were still sleeping or awakened.

In the frightened shouts and screams of the Turks, the horizontal knives in the hands of the Tang soldiers who participated in the battle quickly swept towards the Turks' bodies, most of the Turks who were not a little defenseless, and they didn't even get up on the bed, they were killed by the sharp horizontal knives in the hands of the Tang Army, not to mention picking up arms to resist, a few clever ones, when the weapons in the hands of the Tang Army sergeants had not yet greeted them, they jumped out of the door or window and prepared to flee, but there were also Tang Army sergeants guarding outside the house, As soon as the bodies of these agile Turks landed, or even before they landed, the horizontal knives in the hands of these Tang army sergeants had already slashed at them.

When the sergeant led by Liu Yi was still slashing and killing the Turks in the stockade, the loud sound of horses' hooves had already been heard from far and near, and it was the sergeant led by Zhang Qianxuan, who had received the signal, came from the place of stay, and soon arrived near the stockade, and quickly passed through the passage where the drawbridge had been opened.

The Tang Army sergeants led by Liu Yi were all very good, and they were never ambiguous when they killed people, and there was no sound during the raid. It was only about two quarters of an hour, most of the hundreds of Turks guarding the town were slashed and killed, and when Liu Yi ordered the sergeants to search for the possible surviving Turks, he also ordered the sergeants to prepare to leave At this time, prepare to chase after the large army that had already passed through here.

As long as our army marches fast, even if there are Turks who have slipped through the net, it is impossible to reach the Turks' tent before our army, and no one will report it, and it is impossible for the Turks in the tent to know the whereabouts of our army, so that our army can launch a surprise attack on it...
