Longmen Canyon is not a valley, but a dirt road mixed with soil and rocks, intermittent, resembling a ravine on the Loess Plateau.

The thousand-man centaur team is divided into two parts, the front team is Qi Guoyuan's minions, and the back team is a fully armed sword and shield soldier, the two are five miles apart, echoing before and after.

Strange to say, before he met Qi Guoyuan, Yang Shuang could fight more than a dozen battles in one day, destroying hundreds of bandits, and traveling up to sixty miles a day.

But since he met Qi Guoyuan, the thief has also encountered it, otherwise there will be no corpses on both sides of the road that will have time to be collected after the battle is killed, but the special sword and shield soldiers are not useful, and on the other hand, the more they open the way, the more they fight.

Less than three days after the trip, Qi Guoyuan once again led two ruined men who had never seen him to report to work.

"Qiyu Metropolitan Governor, the former army has a surplus of food and grass, do you want to discard some of it?"

When he broke away from the Yujuluo army, Yang Shuang prepared ten days of rations for the five hundred sword and shield soldiers in order to prevent accidents.

After the incorporation of Qi Guoyuan, the ten-day ration was removed from the previous consumption, and a thousand people could only eat it for three days.

Otherwise, he would not have ordered to arrive at the Dragon Gate Inn within three days.

Now hearing Qi Guoyuan say that there is a surplus of grain and grass, Yang Shuang is a little confused, even if he suppresses bandits, how much food can he get?

"Where did you get all this food?"

"Back to the Metropolitan Governor, this is Liu Wei, a friend of the last general. Yesterday, he heard that the Metropolitan Governor was passing by here, and he brought a hundred carts of baggage to serve! Qi Guoyuan drew out the thin man on the left, and then continued, "This is Li Du, a friend of the last general, who also heard about it."

"Wait!" Yang Shuang waved his hand to stop the nonsense of this goods, in the past two days, there have been no less than twenty good brothers he has introduced!

"Tell the truth!"

"Back to the Metropolitan Governor, this year's Tuguhun drought, the Longmen Dart Bureau has a strong idea, and there is a green forest carrying a bearded guest with a ranger to escort him personally, and the friends on the road can't survive.

"Dadu Governor Kaien, as early as when Dadu Governor waved the Mark Yang Pass, the small one wanted to take his subordinates to defect, but the road was far away, and the Tuyuhun army was on the border, so I couldn't get by!"

As soon as Qi Guoyuan's words fell, two men who looked like beggars bowed their heads and bowed.

Yang Shuang picked up the two of them with the back of his knife and looked at the newly recruited pioneer, "How many soldiers and horses are there in the front team now?" ”

Qi Guoyuan smiled and scratched his head, "No more, no less, just two thousand!" ”

"Plenty of food?"

"Liu Wei and Li Du came to vote, robbed Tuyuhun of a bunch of baggage, and it was enough to hold on for half a month and arrive at the Longmen Inn!"

"Oh?" Yang Shuang raised his eyebrows and looked at the two men who didn't seem to match their strength, "Do you know the movements of the Tuyuhun army?" ”

"Returning to the Grand Governor, Murong Fuyun seems to want to raid Zhangye and send 20,000 troops north to Daheigou!"

Yang Shuang turned his head to look at Zhong Kui, who unfolded the map.

Daheigou is not nameless, it should be called Heihe in the future world, but it is not the Heihe in the northeast, but the giant river that runs north-south and crosses the Qilian Mountains!

Qinghai Lake in the south and Zhangye in the north!

"Murong Fuyun, this name sounds familiar!" Yang Shuang looked at the generals behind him.

"Big brother, could it be that this person is the king of the West Sea who helped Ma Lao Er sell salt? The son of Murong Quarü, the great Khan of Tuyuhun? Shi Da's memory suddenly became a little stronger, Yang Shuang was about to praise a few words, but he continued to say to himself: "I don't know if Ma Lao Er got Qinghai for Lao Tzu, swimming across Qinghai without sinking, also known as Longzi, really a good horse!" ”

"That's right! Yes, Manager Shi is right, Murong Fuyun is indeed the King of the West Sea, also known as the Little Khan, who is very domineering, rampant throughout Tuyuhun and no one dares to take care of it! Qi Guoyuan took over the conversation.

Yang Shuang didn't answer, picked up the map and watched it again.

The map he copied had no scale at all, and he couldn't measure the actual distance with dimensions, so he needed to estimate how far he was from the Great Black Ditch according to the vague memories of later generations.

Not only that, but they also sent sentry cavalry to explore the road overnight and find traces of Murong Fuyun's 20,000 soldiers and horses.

"Do you two know if the King of the West Sea has sent troops?"

"Back to the Grand Governor, I need to go back and ask the little ones!"

"Me too!"

The two men hesitated a little, the military family must not be sloppy, otherwise the way to survive at risk would be gone.

Yang Shuang waved his hand, ordered the two of them to go by themselves, and then looked at Zhong Kui, "In the past few months, has there been news of Yumen Pass and Dunhuang?" ”

Zhong Kui lifted the cloth pocket on his side, rummaged through it, and took out two pieces of parchment, "In the past two months, two pieces of news have come from Yumen Pass, all of them are safe!" ”

"What about Dunhuang?"

"No news!"

Yang Shuang rubbed his sideburns, he had long suspected Lao Hei's true identity.

In the original plan, he thought that Lao Hei would not leave Dunhuang, but when he met Qi Guoyuan, he suddenly remembered that this time when he entered the Central Plains, among the hundreds of civil and military officials of the Great Sui Dynasty and the generals who deployed defense in the Northern Regions, he did not see a very important person, and even affected the deployment of the Western Regions!

Dou Rongding!

Yang Jian's brother-in-law, the governor of Liangzhou who defeated Apo in history, the left and right generals of Wuwei!

He remembered that when Apo was captured alive last year, Lao Hei seemed to have returned to the Central Plains once, and with great ability, he changed the household registration of Shi Da, Niu Er, and Sanwazi to a military household!

Liu Fang was only General Zuo Wuwei, and the highest level at that time was only five grades, and he didn't have such a lot of energy at all!

From this point of view, Lao Hei's identity is not trivial.

Sha Bo slightly south, and now Zuo Wuwei will definitely be convicted if he does not retreat.

If the guess is correct, Gao Ying's ten ** will be dismissed and sent back to the court.

And the successor is Lao Hei!

The governor of Liangzhou, the general of Zuo Wuwei, and it may even be the general of Zuo Wuwei!

As the saying goes, different positions lead to different demands.

As the lord of Dunhuang, Lao Hei may do his best to protect Dunhuang.

But if Lao Hei is promoted to the governor of Liangzhou, focusing on the overall situation, Dunhuang without the slightest military significance is very likely to be abandoned like the year before last!

The central Apo will not go south, it does not mean that the Tuyuhun army in the south will not go north, and when the time comes, Yangguan and Yumen Pass will be in danger!

In the news from the dart master before, Tuyuhun only had 8,000 soldiers and horses, but now Murong Fuyun went north and brought 20,000 with him, which proves that the news is wrong!

How?

As the main general, Yang Shuang can't take risks, let alone do what he wants to do desperately.

Plan before you act!

"Shi Da took twenty horsemen first, notified two thousand soldiers and horses at Yumen Pass, moved south to Yangguan, increased vigilance, and guarded against Tuyuhun!"

"In addition, Niu Er, lead ten generals, and rush to the North Pass overnight to prevent the western Turks from advancing eastward!"

"Liu Ling, go to Shule and continue to guard the blocked Silk Road!"

Passing on the orders one by one, Yang Shuang helplessly found that there were too few generals under his command!

When Zhong Kui went to Yiwu, only Lu Xiaobu and Qi Guoyuan were left by his side.

"Big brother, shall we?" Lu Xiaobu was a little cowardly, as soon as the brothers left, if the boss really wanted to attack Murong Fuyun's 20,000 soldiers and horses, he would definitely be the vanguard.

Through the Daxing City Metropolis, he fully realized the gap between himself and several brothers.

"Qi Guoyuan, An is waiting to make every effort to investigate the movements of Murong Fuyun's army, and as soon as there is news, you can return!"

"Yes, Grand Duke!"
