"But don't worry too much, as far as I know, my father has a deep friendship with the chief steward, not to mention that I am still serving under the chief steward, when things are critical, you can ask my father to move reinforcements, he will definitely not stand idly by." After Xue Renyue gave a general introduction to the current situation in Wuwei County, he looked at Li Wen's frowning brows and said with relief. This is not Xue Renyue's own nonsense, he once sent a letter to his father when he was the guard of Wuwei County, telling about his current situation in Wuwei County, hoping that he would see the love of his father and son and send troops to help him when he was in danger.

Xue Ju read the letter sent by his second son, and secretly sighed in his heart, his second son, who could only read with his head bored, revealed a sleek and shrewd speech at this time, and it was a smart decision for him to let Li Wenyuan take his second son to the Western Regions to take his second son. Especially after seeing the information on the letter that Li Wenyuan sent troops to attack the Western Turks, he was even more stunned for a long time, and when he was still thinking about small profits in China, Li Wenyuan had already begun to take steps of expansion under the banner of the Great Sui. Foreign wars are an excellent place to produce heroes, and Huo Quzhi, who defeated the Saiwaihu people for thousands of miles, has become a famous general through the ages and is admired by the world.

Thinking of this, Xue Ju wrote a letter back to his son, and what he said in his heart was to repeatedly tell Xue Renyue how to be cautious when serving as the pacification envoy of Central Asia, and treat the Hu people differently from the Han people, Xue Ju, who has been dealing with the Hu people for a long time, told Xue Renyue that the people on the grassland only identify with the power, and it is their creed to respect the strong, so when dealing with the Hu people, they must not be soft when they should be tough, and they will only add a lot of trouble to themselves and bind their hands and feet. In addition, when building a city outside the fortress, try to build it by the mountains and rivers, so as to facilitate the collection of mountain stones as the materials for building the city, and open a canal to divert water into the city as a source of water for the residents in the city. There was water to last long enough when the city was besieged, and the mountain was to reduce the defenders in one direction, intending to allow the defending army to concentrate its forces on the remaining three sides and increase its ability to resist enemy attacks. In the end, Xue Ju used very solemn and rigorous official wording to give his second son Xue Renyue a guarantee, once the Turks sent troops to attack Wuwei County, then no matter who the Wuwei County guard was, his side would immediately send troops to rescue Wuwei County, but if Liang Shidu's people came to attack the city, his side would not send troops to rescue Wuwei County, after all, Liang Shidu's subordinates were mostly rabble, if they couldn't even resist the attack of this army, then Wuwei County would directly give up to Liang Shidu.

Xue Ju handed the reply letter to the messenger and asked him to take it back to Wuwei County and hand it over to Xue Renyue in person. You must know that the alliance and mutual assistance agreement signed by Xue Ju and Li Wenyuan is only the two of them and the forces behind Xue Ju, and no one else knows about it, and Li Wenyuan has repeatedly told Yang Guang that before his death, this agreement must not be exposed, Li Wenyuan hopes that this agreement will be used as a dark chess game to give the opponent a fatal blow at the most critical time, and become the last element from defeat to victory.

Xue Renyue got Xue Ju's reply, and his heart was settled, and after having confidence, Xue Renyue began to arrange the defense of Wuwei County, because he didn't have to worry about the threat of Xue Ju in the southeast, Xue Renyue focused on arranging the army on the Great Wall, and facing the Liang division in the northeast.

At this time, Li Wenyuan's internal military deployment was like this, the garrison of the Great Wall was the defensive force left on the Great Wall by the Sui Dynasty, at this time the Central Plains was in chaos, the rule of the Great Sui was about to fall apart, and Yang Guang, who was in the south of the Yangtze River, was even more unable to control the troops stationed on the Great Wall in the north to defend the Hu people, let alone pay any military salaries.

Li Wenyuan reached out at the right time to take over this army, and then formally established the ownership of this army at a meeting with the army officers on the Great Wall, and from that day on, the Great Wall garrison force was formally established, and this army had only one task to guard the defense line of the Great Wall and stop the desire of the Hu people to invade south. At the same time, since this army has accepted Li Wenyuan's reorganization, it must abide by the military law set by Li Wenyuan, and Li Wenyuan will also pay them military salaries, and will do his best to take their relatives to settle in the Western Regions and enjoy the treatment of military dependents.

After five rounds of rotation and rest training, the combat effectiveness of the Great Wall garrison was somewhat higher than before, but because Li Wenyuan's troops did not have extra troops to replace them on the Great Wall at that time, these troops only received intensive training related to the defense of the Great Wall, and also learned to use muskets and fire bottles. This pressure injection device can spray fire oil nearly 100 steps away, and then ignite it with rockets to ignite a raging fire under the Great Wall to block the attack of the besieging army, and can also be used to burn the enemy's siege equipment.

In the long war between the Central Plains and the Saiwai for thousands of years, the steppe people learned to build siege equipment, the Central Plains people learned to use rockets to ignite the siege equipment of the steppe people far away, and the steppe people then used raw cowhide to cover the outside, blocking the ignition of the rocket to the siege equipment, so that the Central Plains people can only use the bed crossbow with very high cost and maintenance cost to destroy, because of the high cost and inconvenient movement, so it is rarely arranged on the Great Wall, and every time the Turkic people attack the city, they will cause great casualties to the garrison of the Great Wall.

But now Li Wenyuan has brought the "fire dragon" to the garrison of the Great Wall, which can spray fire oil into the besieging troops from afar, and can be ignited from afar with rockets, so that the Turks must pay more price to climb the Great Wall, so the defense of the Great Wall in the north does not need Xue Renyue to worry about for the time being, so in addition to the Sixth Army stationed in Zhangye County to be responsible for local stability, Xue Renyue applied for the first division of the Seventh Army to cooperate with the local militia to form a garrison stationed in the direction facing Liang Shidu.

"The mountain rain is about to come, the wind is full of buildings, and the Liang division in the east is already gathering his troops to march to our side, I was transferred by the general manager to the pacification envoy of Central Asia, and this burden is still to be shouldered by Uncle Li." After Xue Renyue finished introducing the current defense matters of Wuwei County, he said to Li Wen with a smile. Since Li Wenyuan blurted out a sentence when discussing the situation in the country that was about to fall apart with the people of the staff group, the phrase that the mountain rain is about to come and the wind is full of buildings has been widely circulated, so Xue Renyue also borrowed it this time.

"What are you afraid of, I'm a person who died once. But you, Childe, are in Hudi after you get out of the jam, and you have to be more careful in everything. ”
