There is a desert area not far from Black Sand City, and the wind and sand here are particularly large. When the wind blows, the sky is full of sand, and the sun in the sky will become hazy because of this, giving the illusion that dark clouds are coming.

With the advent of late autumn, the climate here became dry and cold, and Li Shizhi could only wear Turkic fur clothes to keep out the cold, but his hair was still combed in the style of the Central Plains, so his dress looked a little nondescript. Obviously, the assimilation capacity of Turkic culture was limited, and it was difficult to influence a person from the Tang Dynasty like Li Shizhi in a short period of time.

At this time, the news of the victory of the Turkic army of Musi Khan over Qarluq had reached the city of Black Sand, and the Turks in the city were all vying to celebrate. Only Li Shizhi found the minister Tun Desire Valley and said: "Now you can start preparing to escape from Black Sand City, lest you be caught off guard and become a prisoner of the enemy army in vain." ”

Tun Desire Valley was surprised: "The Khan won the first battle, and now the shape is beneficial to us, where does Li Gongzi say this?" ”

Li Shizhi did not answer Tunyugu's words directly, and asked rhetorically: "You are also an old man who has been on the battlefield for a long time, and the younger generation takes the liberty to ask, what is the most important thing in fighting a war?" ”

Asked by a junior whose beard has not yet grown, Tunyugu was a little displeased: "Naturally, it is the courage of the soldiers, and all creatures living in the grassland follow a truth, the strong eat the weak and are eaten!" ”

Li Shizhi said disapprerovingly: "I think that when the strength of the two sides is a foregone conclusion, it is difficult to change, and what can be controlled is how to use the strength in hand." A wise commander in the use of military force has nothing more than one purpose: clarity of thought. ”

Lust Valley frowned and groaned. Li Shizhi said: "How to win a war, the commander must first understand what path should be taken and what the purpose is, for example, some take the grain road to prevent the enemy army from holding it for a long time, and some take the road of capturing the thief and capturing the king first, each with its own number of ways. The similarity is that they all know what they want to do and how to achieve it...... Let's look at the Khan's war against the three surnames such as Gelulu, but it is just revenge for angering their betrayal, but the timing is not right, at this time the Tang army has been deployed everywhere to watch the tiger, what is the Khan's thinking and what is the purpose? How much significance does it make to win a battle that doesn't help you in any way? Is it worth being so elated? ”

Tun Desire's expression changed slightly, and he subconsciously nodded and said, "Then does Li Gongzi think that King Xue Chongxun of Jin has a clear idea?" ”

Although Li Shizhi had no good impression of Xue Chongxun, and regarded him as the culprit who usurped Li Tang's power and caused his own downfall, he still talked about the matter when it came to this: "Xue and his comrades have won many victories, regardless of whether it is all due to luck, he must have his strengths. The clarity of his thinking on the use of troops against the Turkic Khanate this time is clear at a glance: first, it is necessary to build momentum and assert its own righteousness, using the Turks as the source of brutality and evil, so as to use its power to win over the forces in its favor and isolate and weaken the Turks; Then gradually encroach, the shape shì continues to develop in the direction of self-benefit. The Xue clan is not in a hurry at this time, and has not yet transferred troops out of the Hetao, obviously their thinking has already been determined to control the form! ”

Li Shizhi looked at the southwest direction, and was silent for a long time in the wind: "Under such a strategy, the first battle is not about winning and actually playing, but about building momentum. If I were in his place, I would have to choose the Turkic capital of Black Sand! The Turkic Khan led the main force in the northwest, and was defeated and neglected to take precautions, which was an excellent fighter; Although it is not very profitable to take the current Black Sand City, this city is called the Turkic Capital, and its reputation is extremely beneficial to building momentum. At that time, some loyal and wavering tribes were too easily won over by the Tang Dynasty...... Now the Mosi Khan is making a big move to punish the betrayer, but he doesn't know that the people's hearts are fluctuating at the moment of the general situation, can he be punished? ”

Lust Valley's expression was cold: "Li Gongzi thinks that the Tang Army will take this opportunity to attack Black Sand City, so he made a plan to escape as soon as possible?" But now the Jin King's men and horses have not yet arrived in the Hetao area, and the army has gathered and I don't know when it will be, how can he fight Heisha City, can he fly over? ”

Li Shizhi sneered: "The Murong Xianbei people and those tribes in the east who are attached to the imperial court, anyone is possible. As far as the current shape is concerned, are you still worried that there is no one available for the Xue family? ”

Li Shizhi's words were aggressive, of course, he didn't really want Tunyugu to prepare to escape, but hoped that Tunyugugu's own strength would influence the Khan's decision-making to make some necessary precautions against Heisha City. The old man was a wiser and more enlightened person among the Turkic rulers, and he should be able to figure out what was going on.

Sure enough, Tun Desire Valley took Li Shizhi's construction seriously, although he didn't think that Black Sand City would inevitably be attacked, but thinking that this city was not far from the area controlled by the Tang army, and at this time, it was necessary to be vigilant. So he found Tuoxi, who stayed in the southern court, and persuaded the son of the Mosi Khan. Because Ashina Mosi's other son, Yang Izhi, was too influenced by the Tang Dynasty and was not favored by the Turkic nobles, in fact, Tosi was the heir of Mosi's Neiding, and his speech in front of the khan was naturally more effective.

The Mosi Khan saw Tosi's messenger on the northwestern front, and "when he heard that the Tang army might attack the southern court, Tosi sent people to ask for troops to take precautions." Mo Si was a little displeased and thought that his son was timid, but the ministers around him said that after the Khan left Black Sand City, his precautions were indeed insufficient, and since there was a rumor, he could not take it lightly. Mo Si then divided his army and returned with 10,000 horsemen, and ordered them to obey Tosi's orders to defend Black Sand City.

Coincidentally, when the Khan's reinforcements had just arrived at Black Sand City, the city got the news of the scouts and found that a large group of cavalry had left the city for more than 100 miles, and the direction was directed towards Black Sand City! After hearing the news, Tun Desire's attitude towards Li Shizhi rose to the level of respect, and he could expect that he had to be impressed again, so he valued this Han man who escaped from the Tang Realm more and more.

At this time, the "little khan" Tosi also felt that Tun Desire Valley was very wise, because the person who proposed a precautionary strategy to Tosi was Tun Desire Valley, so Tosi hurriedly recruited Tun Desire Valley to the sweat tent to discuss the plan to retreat from the enemy. Tunyugu then called Li Shizhi together.

The sweat tent is where the Mo Si family lives, and now that Mo Si is not here, Tosi does not dare to sit in that position, but still sits according to his usual habits, and vacates the dimly lit seat in the middle.

When the people had arrived, Toxi said: "It has been found that there are about 30,000 men and horses in the southwest of Nanting, and they are Xianbei people, and they should come from Zhongcheng. This group of people marched quickly, and when they were discovered by our scouts, they were already more than a hundred miles away, and it only took about two days to reach Nanting. How to retreat from the enemy, do you have a way? ”

Tunyugu glanced at Li Shizhi, and then turned to Tosi and said: "Fortunately, the reinforcements have just arrived, but it is still a situation where the enemy is outnumbered, we should immediately assign the troops to defense, use the fortifications to repel the enemy soldiers with ballista arrows, and then quickly send messengers to the Khan's camp, hold on to and wait for reinforcements, and we must not lose the Black Sand City." ”

Although the Turks are not good at building cities and defending the land, they have absorbed the old Goguryeo tribes and other tribes that defected from the Tang Dynasty, and have been able to manufacture some large-scale siege and defense equipment, so the Tunyu Valley has the confidence to say that it wants to defend the city. Moreover, according to the war idea expounded by Li Shizhi, the Tang Dynasty sent troops to fight Heisha in order to build momentum, so for the Turks, no matter what method was used to repel the attack and prevent the Tang Dynasty from succeeding in its goal, it would be beneficial to the Turks.

The reinforcement generals immediately objected: "Cowering into the city and letting them fight?" This is too sloppy, what kind of Xianbei people are something, as long as we meet the enemy on the grassland, we will definitely be able to kill this rabble! ”

At this time, Li Shizhi said lightly: "You don't need to move, and there is no need to rush to destroy the Xianbei army. As the Minister of Lust Valley said, Black Sand City is the focus of this battle. However, I also don't think that retreating to the city is a good way to defend the city, because the Turks are nomadic migrants and are not good at sticking to the way; Rather than that, it is better to give full play to the advantages of cavalry, and arrange the cavalry outside to attack and defend at the outside, and respond to the defenders of the city, which is the best policy. ”

Tosi looked at the hairstyle on Li Shizhi's head with distrustful eyes, and when he saw this, he said: "The first person to foresee the enemy attacking Black Sand City was Li Gongzi, and I also think that his plan is good, please consider it." ”

Tossi then asked, "How to be both offensive and defensive?" ”

Li Shizhi hugged his fists and said: "Soldiers are impermanent, and the generals should take advantage of the situation when fighting, but the overall situation should be agreed first." Since the Xianbei army still has more than 100 miles away, this 100 miles is the depth and opportunity of our army, the cavalry out of the city to travel, looking for opportunities to attack on this journey, the battle is good and solid, and the troops will retreat to find another opportunity if they are not favorable; Therefore, when the Xianbei soldiers approached the city, their sharpness had been lost, and because the flanks were threatened by the cavalry outside the city at all times, they could not attack with all their strength, and the mutual coordination inside and outside the city could make the enemy soldiers unable to advance. ”

This method really catered to the fighting habits of the Turks, and many generals agreed with it for a while. Li Shizhi had stayed in Sancheng for a while, and whether he had seen it with his own eyes or heard about it with his ears, he had some understanding of the tactics of the Turkic nomads, which also came in handy at this time.

Seeing that many people agreed, Tosi said cheerfully: "Time is running out, since everyone supports this method, let's do it!" The herald ordered the cavalry to go out of the city immediately, and the defenders in the city checked the weapons, and we gave the Xianbei people a head-on blow! ”

It was agreed in the Khan's tent that the Turkic troops near Heisha City would be deployed smoothly, and Tosi sent a second group of messengers to report to the Khan of Mosi, and the preparations were completed.

And Li Shizhi, a Han man, can give advice, but he can't have military power, and when the Turks are busy preparing for war, he has nothing to do. When he climbed to the top of the city to observe the defense of the city, he saw groups of Turkic cavalry leaving the city one after another, which looked particularly magnificent in the wind, sand and dark day. It's just that these soldiers and horses are foreign soldiers, and no matter how spectacular they are, they can't arouse Li Shizhi's feelings, but there is something wrong in my heart. G
