It has been a long time since Li Xiang met with Yu Chi Baolin, when Li Xiang left from Tubo, Yu Chi Baolin and Changsun Chong stayed there, and now Changsun Chong continues to take it with him in Tubo.

Although there was no war on the Tibetan side, it was necessary to be able to prevent it, Changsun Chong with more than 30,000 troops has been staying on the grassland of Tuyuhun, and the other generals have returned to Chang'an.

Li Shimin still can't be completely at ease with these generals, although they all started with him in the war, but now the prestige of these generals in the army is too heavy, if anyone has an idea, it is not good for the stability of Datang.

So Li Shimin adopted Li Xiang's method, saying that the tiger father has no dogs, and now it is just right to try, let the descendants of these people lead the troops outside, and the whole family is in the capital, then there is nothing to be afraid of, not to mention that the prestige of these young generals in the army is not heavy, Li Shimin can completely handle it.

"Your Highness."

Li Xiang had already gone out of the camp for ten miles to greet him, and he saw Yu Chi Baolin galloping in the distance, and saw that this figure seemed to be a little bigger than before.

Yu Chi Baolin went from Tubo to Tuyuhun, and then from Tuyuhun back to the capital, and then went to Goguryeo, which had to be at least thousands of kilometers down, and stayed in Goguryeo for about three months before he selected his army.

When the Eastern Expedition to Goguryeo, the imperial court used nearly 200,000 soldiers, Li Xiang did not need so many people, so he only needed to pick out some elites from them, and now Li Xiang's way of fighting is different from before.

"Brother Baolin has been on the plateau for so long, but I didn't expect this figure to be much stronger than before."

Li Xiang is telling the truth, Yu Chi Baolin was the biggest among them when he turned out, and he was eating meat on the plateau these days, but he didn't expect it to grow again.

"Your Highness, don't talk about me, I eat and sleep well every day over there, but I don't have the intention of fighting, so I have more and more meat, fortunately the usual exercises have not been left behind, otherwise it would be a fat body, after His Highness received the letter to me, I immediately set off with my subordinates, and only walked for seventeen days."

Yu Chi Baolin said very proudly that during the three months in Goguryeo, he basically trained his soldiers, and when he went from Goguryeo to the northwest, Li Xiang also asked him to speed up as soon as possible to see how long he could come.

Li Xiang calculated that this time is really a day and night, Goguryeo is more than 5,000 kilometers away from here, and in this era, it all depends on the running speed of war horses, and this person is almost useless.

"But still have combat effectiveness?"

Li Xiang looked at the army behind Yu Chi Baolin, it was obvious that it had not reached the limit, in these seventeen days, most of the people only rested for three or four hours a day, and the rest of the time was to keep hurrying, of course, they could have such a fast speed, which was also combined with the military stations along the way, if the logistics were not good, they would not have such a speed.

"At least seventy percent or more."

Yu Chi Baolin is a real person, it is impossible to brag about this to Li Xiang, when Li Xiang heard this, he also smiled and nodded, but did not let Yu Chi Baolin immediately start the battle formation, it is better to let the soldiers go back to rest first, he believes in Yu Chi Baolin's personality.

When the brothers saw the military camp in the distance, they were really tired one by one, and they all tensed their nerves all the way, even when they were eating, they were on the back of the war horses, and now they could finally take a good rest, and many people did not take off their armor after being assigned to the tents, and they just turned their heads and began to sleep.

Li Xiang knew that Wei Chi Baolin was also tired, so he hurriedly asked him to go down to rest, and in the afternoon of that day, there was a snoring sound in the entire barracks.

"It took seventeen days to get from Goguryeo to here, which is simply unbelievable."

Lord Zhao turned around on the map for a long time, and the route had been marked, he really couldn't believe that all this was true, if the army had been mobilized from that side before, it would have been at least more than a month, and this had to be all the people day and night, but now it has been shortened by more than half.

Lord Zhao didn't know what was going on, but Li Xiang was of course very clear, in addition to the sufficient supplies along the way, the most important thing was that many roads were built across the country, all of which were built by prisoners of war.

Although there is no cement asphalt or anything like that, Li Xiang has already begun to burn cement, and now cement roads have appeared around Chang'an City, and I believe that in the near future, this kind of cement road can be widespread throughout the country.

"When His Royal Highness defeated Tuyuhun and began to build roads, there were still many people in the court who opposed it, thinking that His Highness's move was a waste of money for the people, but I didn't expect it to be visible now, the pipeline benefits the people in peacetime, and the army gallops during the war, which is indeed a long-term chess."

As a member of the civil official group, Lord Zhao is naturally reluctant to praise military generals, even if Li Xiang is the emperor's grandson, but at this moment, Li Xiang's identity is more of a military general.

"Lord Zhao, don't praise me, if there weren't so many prisoners, this plan wouldn't have been carried out so well, especially after we captured Goguryeo, the number of prisoners in the country increased, and now according to not very comprehensive statistics, after all these roads are repaired, at least 150,000 people will die."

Li Xiang whispered, in this era without industrialization, if you want to carry out large-scale infrastructure construction, then you have to consider the loss of personnel, but Goguryeo has a large population, and one by one has committed a lot of crimes, so the best way to deal with you is to let you build roads and work.

"If Your Highness is not benevolent and righteous, they don't even have the opportunity to build roads, if we follow the national policy set earlier, the emperor will slaughter Goguryeo."

Lord Zhao didn't feel that there was anything wrong with what Li Xiang did, after Li Shimin's failure in the eastern expedition to Goguryeo, he had already given an order to the outside, and as long as Goguryeo was defeated in the future, all men and women would be killed, and now they were given a chance to work, which was already able to let them live for a while......
