Everyone had to look at the map together, and some clues could be seen.

If it is said that it is from the grassland north of Yanmen, then it should take the mountain road in the north and pass through Wuquan County. The location of Wuquan County is in the northeast of Beiyu County, about 20 miles or so, just on the Jingxin Expressway in the later world.

If Budugen wants to go south, he generally goes to the north, just for insurance, so he adds a Wuquan County. Now Wuquan County is not set up, so Beiyu County has become the forefront of the resistance to the roots of Budu.

"In other words, if the root of Budu is going south, then the first warning should be Beiyu County, not Dingxiang County." Liu Tao pointed to Tuyu, "On the side of Dingxiang County, the lead should actually be to Yanmen County." ”

There are mainly mountain roads that can run through Liangcheng County in later generations, and it is up and down 80 miles before and after. The mountain road is not easy to walk, but it is a two- or three-day journey, and you can almost come from that side.

Fifty miles southeast of Liangcheng County, is Qiangyin County, which is a city in Yanmen County that hangs alone outside the Great Wall. The reason why the castle was set up here is, in the final analysis, because it is close to Shiozawa, which is later known as the inland lake of Daihai.

It belongs to the inland saltwater lake, in the final analysis, this is the meaning of the existence of Qiangyin County.

"Since there is Shiozawa, then here, can Budugen really monopolize it?" Guo Jia proposed a direction for thinking. When it comes to the issue of salt, then don't think about it, this must also be a battleground for Xianbei soldiers.

"In addition, starting from that side, the terrain is gradually flattening, and it is more suitable for the Xianbei tribe to run. Qiangyin County is not far from Dai County, and there is still a great possibility that Kebi Nengbu is active. Xun Yu also agrees with this view.

A lot of things, just looking at the map, can be seen to some extent.

"Then the conclusion is almost there." Liu Tao nodded, "This time, it's not the root of Budu, but the Kebi Neng Department." But why did they come here just in winter? ”

If you want to say that you are not very confused, in the memory of 186 years, that is, next year, Xianbei will be in December Koumer State. In December, you can go south in the deep winter, and in the early winter, the weather is not completely cold, so you are even less afraid!

"This year's winter seems to be relatively warm, so I shouldn't have so many scruples." Lu Yan thought for a moment.

"What's more, we didn't expect them to come in early winter, so it's naturally even more impossible to know about the root of the step. We even need to come up with a hypothesis, what if the Kebi Neng Department comes to explore the way, and the roots of the follow-up steps will go south? Jian Yong put forward a new point of view.

"No, no, my subordinates think that this should just be Kebi Nengbu's own meaning." Guo Jia shook his head, "In the clouds is the recruitment point at the root of Budu, when you need to recruit and loot, just go south and walk around." This is also an important foundation for his confrontation with the Kobi Neng Division, this is his hunting ground, and he will not allow others to come and hunt. ”

"What if he thinks that the lamb in this hunting ground has become a man-eating beast, and he may not be able to cope with it, so he turns to Kebineng?" Jian Yong retorted.

Liu Tao's ability can only be fixed in one field, so it is difficult to say whether Beiyu can ensure that the root of the step does not go south. Perhaps, Bu Dugen deliberately did not go south, and it was possible that Liu Tao and Kebi Nengbu would fight inseparably before going south to pick up cheap.

"In that case......" Xun Yu pointed to the map, which was where Yuanyang County was located.

Yuanyang can be said to be Liu Tao's arrival in Yunzhong County, the last county seat in the north that did not have a abolished county, and now it has become the rear.

In other words, it is precisely because it is in the rear, so as a city that communicates Beiyu and Dingxiang County, its role is much more important than the original.

"Just in case, I decided to set up camp here with Yuanyang County as the rear." Liu Tao pointed to the side of Yuanyang County, "The whole army is ready and then goes out, it should be a day or two later, and then calculate the distance, when you arrive at Yuanyang County, it should have been almost five or six days." ”

For five or six days, it is impossible for the Xianbei army to be completely unmoved. The biggest possibility is that Dingxiang County has been surrounded, and at the same time it has begun to loot that area over there.

Of course, it is estimated that there will be nothing looted, and the side has been completely militarized, and the grain has been harvested early and stored in the granaries in the city. Guan Yu has been in the past for so long, in the final analysis, he has built several large granaries in the city.

At the same time, several wells were dug so that even if they were surrounded, there was no need to worry about food and water.

"I have inquired that in the past, Xianbei fought in the grass valley, and they rarely attacked the city, after all, they did not have this ability. Therefore, they mainly plundered the localities, plundering grain, grass, materials and people. Jian Yong said slowly, he was not in vain during this time, "They will not surround Dingxiang County, they will keep moving, and when we pass, there may be encounters!" ”

"So it's mainly cavalry, and the crossbowmen are responsible for containment, and it's almost impossible to catch up with them by relying on foot soldiers." Liu Tao had expected it.

The reason why it is difficult for the Hu people to calm down is that a big man lacks horses and cannot catch up with the other party. The second is that the imperial court is too unfamiliar with the grassland, and if there are no landmarks, it is easy to get lost, and the other party can easily use the grassland to fight back.

When the number of Hu people is large, you can still see some tribes after walking a while, so you can gain some gains.

But when the battle reaches a certain level, the other side directly plays guerrilla warfare, and at this time the gains are getting less and less, the expenses are getting more and more, and the battle is becoming more and more difficult to fight. If you are blinded by the war dividends in the early stage, then you are doomed to be sad in the future.

The temple is calculated to this point, and it is almost the end, and many things can't be calculated, especially the encounter thing, which is really half a day, and the actual fight is something else.

Of course, Liu Tao's situation is a bit special, if he is willing, he will walk ten miles every day, and then rely on the insight of the wind dragon to look all the way over, what is the situation of the enemy army, how many people, how to come, can generally still be seen.

After all, a radius of ten miles is still a bit small, but if you want to level up, it means that you need to increase the level of qi magic, which means that you need to consume 1 free skill point.

If he could, at this stage, he decided to focus on the light magic and meta-transformation magic first.

As expected, it only took an hour for the whole army to assemble, but it took a day to move the supplies. arranged the city defense, so Zhang He was left behind.

He regretted that he couldn't go out with the army, but he also knew the importance of his responsibility to stay behind, so before the army left, he only solemnly promised that he would swear to defend Yunzhong County.

"The enemy army is heading towards Dingxiang County......" On the first day of the expedition, Liu Tao said, "It is expected to arrive in a day." Xianbei rarely attacks cities, so it is very likely that after looting, they will march towards Yuanyang County, and we must move forward quickly! Inform the whole army, speed up! ”

"Whoa!" The generals responded one after another, and at the same time sighed: It's really convenient to have a heavenly eye!
