When he came down, Li Er invited Gao Buer to come to the imperial study.

"Uncle Huang, this Western Expedition still has to work for you, this battle is related to the trend of national fortunes in the Tang Dynasty in the future, and I ask Uncle Huang to bear more."

You said that this girl is related to the fortune of the Tang Dynasty, what else do I have to bear, I know that Li Er's goods are getting darker and darker now, so Gao Buer didn't say much.

"Your Majesty can rest assured, the minister will go back to convene a military meeting, except for Li Jing's 50,000 horses and horses in the capital, Daozong and Xue Wanche will rush to Hexi, and the other will rush to Lingzhou, the military affairs are urgent, and the minister will not delay."

"Is Uncle Huang going to send troops immediately? It's snowing heavily. ”

"The soldiers are fast, we just want to take advantage of this bad weather, our own people can't think of it, even the Turks can't think of it, surprise it, attack it unprepared, so as to play the effect of a surprise army."

"But how to ensure the food and straw of tens of thousands of people, besides, there is heavy snow everywhere on the grassland, and it is inconvenient to march."

"Your Majesty, rest assured, the minister knows a thing called a sled, which is definitely a sharp weapon for the snow field march, and the supplies can be transported through this thing, so it can be safe."

As he spoke, he drew a sketch of the sleigh used by the people in the Northeast in the later generations to explain to Li Er, and Li Er was overjoyed when he heard that Li Er stroked his palm: "There is no improper solution to all problems in front of the emperor's uncle, and I am very fortunate in the Tang Dynasty. This is all the confidence that the popularization of assembly line operations has brought to Li Er.

Gao Buer nodded and continued: "I am going to send Li Jing to lead thousands of cavalry tomorrow, because the grassland is different from my Central Plains, the grassland nomads, there is no fixed place, although according to the secret agent report, Jieli's base camp is in the Evil Yang Ridge, no one can guarantee whether the next step will be to move west to Jincheng, Li Jing raised troops with one man and two horses, one to march fast, and the other to grasp the movements of the Turks in advance, I led Xu Shiji, Chai Shao and the team to set off five days later. ”

"Okay, once you enter the battlefield, the military situation changes rapidly, and the imperial uncle can decide on his own to attack."

Gao Buer nodded, gave a salute and returned to the palace, Li Daozong, Li Jing, Chai Shao, Xu Shiji, Xue Wanche and others were already waiting, and the military map sent by the Ministry of War had been unfolded.

Gao Buji came in to see the excitement of their discussion, and said loudly: "How are you discussing?" ”

Everyone saluted together: "See the prince!" ”

Gao Buer let everyone be exempted, and Chai Shao said: "The last general thinks that we should wait a few days before sending troops, at this time, the heavy snow is blocked, and the supply of military food is only afraid that it will be very difficult." ”

Li Jing said: "The last general doesn't think so, the last general thinks that the sooner the army is dispatched, the better, at this time, as long as we send a cavalry, we can get unexpected results, the Turks on the steppe communication is not smooth, giving us an excellent opportunity to break through." ”

Li Daozong, Xu Shiji, and Xue Wanche also nodded in support.

Gao Buer was silent for a while, and said to Li Jing: "If you are given thousands of cavalry, let you be the first to enter the grassland, and find out the enemy's situation for the army, how many men and horses do you think you need?" ”

Li Jing said categorically: "If it is just to find out the military situation, three thousand elite horsemen are enough." ”

Xu Shiji said: "General Li, have you figured out how to supply the problem. If you go out of the steppe with 3,000 elite horsemen, and the army cannot arrive in time, that is, there is no food and grass and no reinforcements, and once you are besieged by the Turkic army, you will be in danger of extinction. ”

Li Jing said: "I have already thought about it, we can ride one person and two horses, each person with supplies for seven or eight days, attack for four days, no matter where we go, we will immediately turn around and return, and we can be safe." ”

Li Daozong worried: "Having said that, it is still unknown to us what the grassland snow disaster will be, and we must know that if the snow is too deep, it will also be a problem for our march and the transportation of grain and grass." ”

While they were arguing, Gao Buer sat down in front of the bookcase and spent another sketch of the sleigh, and said, "How about you come and see this thing?" ”

Everyone is a military expert, and when they saw the sleigh all admired Gao Buer, Gao Buer did not say much: "This thing is a sled, also called a land boat, which is most suitable for use in the snowy wilderness, only one horse is needed, in order to ensure speed, we use double horses, and the craftsman is the supervisor of the production, Li Jing immediately went to prepare, and set off with three thousand fine horses tomorrow night at the latest." ”

Li Jing received the order, Gao Buer continued: "Daozong, Xue Wanche, you rush back immediately, I have ordered eight hundred li to urgently transmit this map to Hexi and Lingzhou, I, Chai Shao, and Xu Shiji will lead the army to set off in five days, Xue Wanche will immediately send troops after returning to Lingzhou, and rush to the Evil Yang Ridge to meet me, Daozong, you have left Hexi, you don't have to rush to the Evil Yang Ridge, you need to wait for Jieli who fled west here in Dingxiang, and block it, to buy time for the army, I will set Dingxiang as the final battlefield of Hejieli." ”

The lieutenant generals said in unison, and then Li Daozong and Xue Wanche hurried to Hexi and Lingzhou, and when they arrived, the soldiers, horses, sleds and other supplies would be ready.

Gao Buer took Li Jing, Chai Shao, and Xu Shiji to the barracks, and from this moment on, they will take the barracks as their home, and Gao Buer will not allow the generals to leave the army during the war.

In the army, the three thousand elite soldiers selected earlier were preparing to pack, three thousand elite horses, one man and two horses. Gao Fuji ordered them to match the crossbow with two hands, and the crossbow at this time had been modified to be able to fire eight arrows in a row, and all the heavy equipment was packed and ready to be placed on the sleigh, which could reduce a lot of physical strength when the horses were traveling.

In the evening of the next day, Li Jing headed north with 3,000 men and horses and 800 sleighs, and soon disappeared into the endless snowflakes.

Before leaving, Li Jing and Gao Buji agreed to see each other in Evil Yangling.
