"Deputy Marshal, Deputy Marshal Hao Wei of the Right Route Army sent a letter."

At the head of Didao City, Li Yu was looking from afar against the wall, and Zheng Lu, the secretary in charge, walked behind Li Yu and said softly. Li Yu didn't reply, and said:

"But Vice Marshal Hao urged me to cross the river and attack Hezhou again?"

Zheng said:

"Exactly."

Li Yu said:

"Is there any text from the prince of Longyouxingtai?"

Zheng said:

"Xingtai also has a text, urging the deputy marshal to cross the river through Luohe Prefecture, join forces with the Right Route Army in Shanzhou, and restore Hehuang."

Seeing that Li Yu didn't speak, Zheng Lu asked:

"There is something unclear under the subordinates, please show the deputy marshal."

Seeing that Li Yu did not object, Zheng Lu continued:

"Deputy Marshal, when our army just recovered Didao, the Tubo people were defenseless and their troops were scattered, it was a good time to march in, I don't know why the deputy marshal did not move and waited for the Tubo army to gather here?"

Li Yu said:

"Did you hear something?"

Zheng said:

"The subordinates don't dare to say it."

Li Yu smiled faintly and said:

"You don't know if you don't say so-and-so. It's nothing more than insinuations and the like. Do you think so about me? ”

Zheng said:

"The subordinates don't dare."

Li Yu said:

"I don't know how fast a soldier is. However, if you are by my side, do you know how many troops Tubo has deployed in Hehuang? Since the pacification of Heshuo, the imperial court increased the troops to the west, Tubo also gradually increased troops towards Hehuang and Hexi, and the soldiers of Hehuang are not less than tens of thousands, plus the warriors of the Qiang, Rong, and Dangxiang ethnic groups, the total number is much more than our army, if our army starts to wave thousands of miles, the progress is too fast, and the place is not easy to clear, these people can gather in the mountains and forests at any time after they escape, and become hundreds or even thousands of large and small thieves, threatening the rear of our army, and secondly, the battle line is extended, and it is not easy for our army to supply. ”

Li Yu paused and continued:

"Thirdly, every time our army occupies a place, it must divide its troops to guard one place, resulting in the dispersion of troops, and the enemy army can rely on its depth to shrink its strength one by one, and finally form an advantage over our army. The imperial court has been accumulating troops for so many years, hoping to fight a war to determine the river, if you are a little careless, it will make many years of work ruined, this marshal bears the trust of His Majesty, how can he be greedy for more and faster, so as to fail? ”

"Our army is gathered here, and the Tibetans will not dare to despise it, and they will definitely gather a large army here to prevent our army from crossing the river. If the commander sends his troops out to go around every once in a while, he will think that our army has not yet been assembled, and soldiers and horses from all over the country will continue to come in. In this way, our army, which originally wanted to compete in one city and one place, could sit back and wait for the Tibetan army from all over the country to open and fight a peaceful battle; Our army, which was originally a labor expedition, became a leisurely waiting; Our army, which was supposed to disperse its forces, was able to concentrate its forces. Our army can turn disadvantage into superiority and passivity into initiative. With 70,000 elite soldiers of the Tang Dynasty guards, Fengxiang, and Shence, who have been exhausted from afar against 100,000 soldiers and horses from far away in Tubo, does the secretary think that the chances of victory are big? ”

Zheng Lu, who suddenly realized:

"My subordinates think it's big."

Li Yu continued:

In addition to the soldiers and horses of the Tubo tribe, the Tubo army also has the soldiers and horses of the so-called four ethnic groups such as Subi, Qiang, Dangxiang, and Tuyuhun, as well as slaves accompanying the army. Moreover, Ben Shuai still has a strange army hidden in the shadows, and if Tubo does not come, it will be defeated. ”

Li Yu analyzed it so thoroughly, Zheng Lu only admired it, and said:

"Liang Gong is high-minded, and his subordinates admire him, but it is not a matter if Tubo is also on the other side of the strait."

A weird smile appeared on the corner of Li Yu's mouth, and he said:

"Isn't our army already moving? If our army moves, Tibet will move. Moreover, in terms of short-term Lizang, he had to cooperate with the actions of our army. ”

Zheng Lu was stunned:

"On the short standing of the Tibetan cooperation with us?"

Li Yu said:

"Just wait and see."

Zheng Yu wanted to wait for Li Yu to explain, but Li Yu did not continue, but turned around and walked down the tower. Because a pro-soldier colonel hurriedly came and said:

"Deputy Marshal Qiyu, Marquis Liu Yu is back."

Zheng Lu knew that this Liu Yuhou was Liu Yanping, Li Yu's personal general. He was originally the Marquis of Yu under Li Shidao's account, and when he was in Huaixi in the first year of Xingzhi, he volunteered to help Li Shidao investigate the war situation in Huaixi, but after he went back, Li Shidao blamed him for disturbing the army's heart and wanted to kill him, but he escaped and joined the army under Li Yu's account. After pacifying Ziqing, Li Yu wanted to protect him to lead the army, but he refused to do so, he just wanted to stay by Li Yu's side, Li Yu didn't want to delay his future, but he loved his talent, so he had to follow his wishes. A few days ago, he suddenly disappeared from the army, thinking that he had a secret business. As soon as Zheng Lu was about to follow Li Yu down to the city, he heard Li Yu command:

"You go and find Li He and go back to the Chinese army with him."

Zheng Lu circled around the city wall, and found Li He, who was commanding the people to strengthen the city defense and repair the military cave, in Xicheng. After two years of training in the army, Li He is no longer the thin appearance he used to be. There is also a calm attitude in doing things. However, Zheng Lu still felt sorry for him, because Li He didn't write much poetry recently. When I asked him, he said,

"There's no time for those idle things."

However, Li He's busyness still had results, and after the county order of Quan Didao, Li He not only quickly stabilized the place, but also spent more than a month training the 2,000 Lintao county soldiers he had just recruited to rectify the city defense. Now it seems that the defense of the city of Didao is indeed much more stable. Looking at Li He's tired appearance, Zheng Lu couldn't help laughing:

"Changji is a new official, so you don't have to work so hard, right?"

Li He smiled:

"Brother Zheng is mistaken, Li He didn't hurry up so much for the new official to take office, it's really cold here, if it can't be repaired as soon as possible, I'm afraid that it will be difficult to deal with the cold weather in a few days."

Zheng Lu was surprised:

"Will it be cold in a few days?"

Li He said:

"Yes, I asked the old man here, there are always a few strong winds at this time of year, and then the next day is as cold as a day, and the swords and soldiers can't move."

Zheng said:

"No wonder the lieutenant marshal is so sure."
