When you go out of Xuanmen pass and walk ten miles north, you can see the boundary monument between the state of Wei and the barbarians.

Twenty years ago, more than 100 miles south from Xuanmen pass were the territory of barbarians. In this distance, there are few people and the economy is not very developed. Most places are covered with tall numbers. But for the state of Wei, this has always been a place that the royal family of the state of Wei wanted but could not get.

At that time, the national strength of the barbarians was stronger than now. Relying on the natural danger of the woods, barbarian troops often lurked among them and harassed the residents of the Wei state in the rear. Moreover, their attacks are very random. If there are local troops stationed, the barbarians will choose to bypass them. If there is no army stationed, the barbarians rush in and plunder wantonly, or they can retreat before the troops of the state of Wei arrive. Even at that time, many towns along the border were in a very special state.

In the territory of the state of Wei, these places belong to the state of Wei, but in the territory of the state of man, these places belong to the state of man. In the small town, it may be the troops of the barbarian state who occupy here today, but tomorrow, the troops of the state of Wei will rob it back, which makes the residents panic all day.

After Xu Ruxian entered the temple, he also found a strange scene here. He applied to the former Emperor Wei Tianlong to lead the troops. Under Xu Ruxian's artistic use of troops, the troops of the barbarian country retreated step by step. At that time, the barbarian troops were very flexible and invisible in the jungle, in a state of advance and retreat. So Xu Ruxian, who was strong at that time, used his unique magic to find traces of barbarian troops in the dense forest, and then pursued them all the way.

Finally, twenty-three years ago, Xu Ruxian led his troops to draw out the barbarian troops, beat them back all the way, drove them back to the deciduous plain, and established Xuanmen pass, which is one of the most powerful passes in the kingdom of Dongzhou.

It is precisely because of the appearance of Xuanmen pass that the barbarians dare not go south again. Later, Xu Ruxian handed over the troops to Zhou fengmiao and returned to the temple. However, the Xuanmen pass still stands there. Although Zhou fengmiao said that he was no better than the blue, he was also a general who could lead most of them. With the three armies formed by Xu Ruxian, he guarded the Xuanmen pass to death, which made the barbarians dare not take a step.

From the border line to the north, it is the deciduous plain. The deciduous plain, together with the autumn wind plain and the flower plain, is known as the three plains of the barbarians, all of which are rich in water and grass. The autumn wind plain is located in the west of the place further north of the deciduous plain. It is the most marginal zone of the temperate zone of Dongzhou continent. It has a pleasant climate all year round, like spring all year round. The river water flowing from the flower plain in the east also brings abundant water to this land, so that the livestock living on it can thrive. In the flower plain in the East, although the climate is cloudy and sunny, it only brings trouble to people's life, but the animals living here are more robust than those on the autumn wind plain.

The main reason is that the flower plain is located in the easternmost part of Dongzhou continent, and then to the East is the boundless sea area. The moist warm wind blowing from the sea every year brings enough rain to the flower plain. On the flower plain, gorgeous flowers bloom almost all year round.

Three days later, Yang Xuan has come outside the Xuanmen pass. Compared with the last time I came here, there was no big change outside Xuanmen pass, but I couldn't see the barbarian army stationed here at that time. Not long ago, the barbarians invaded the state of Wei, but were defeated by the state of Wei. Therefore, their vitality was greatly damaged. Except for the defenders staring at the state of Wei on the deciduous land, no other troops dared to jump in front of the state of Wei.

Yang Xuan stood at the mouth of Qingfeng gorge, while Li Qing followed Yang Xuan behind.

"Childe, this is the most important first place in the defense line between the barbarians and the state of Wei. But all the time, neither the state of Wei nor the barbarians are willing to pass here."

"Why?" Yang Xuan asked curiously. Li Qing was right. The last time he led his troops through here, he found that the terrain of Qingfeng gorge can be called unique. Even the lowest place in the canyon is higher than the outside. Moreover, Qingfeng gorge is narrow at both ends and wide in the middle, just like a big pocket, which can easily accommodate tens of thousands of people and horses. In addition, the two sides of the canyon are narrow. Even ordinary horses can climb up the slopes on both sides of the canyon, but it is difficult for the outside troops to turn in from both sides of the canyon.

"Yes, childe's analysis is very reasonable, but you ignore the most important point. Although there is no one in the canyon, there are countless beasts and poisonous insects, and their strength is not strong. Even if they slap him, they may kill him, but the toxicity attached to them can easily make several soldiers lose their combat effectiveness. Most of the soldiers in the army are real The power is only around the second realm, and the third realm is already a little master. There is no way to deal with these poisonous insects. "

Li Qing said, suddenly looked at Yang Xuan with a puzzled face and asked, "childe, I really want to know why you didn't be harassed by these poisonous insects when you led the army around here?"

"Why?" Yang Xuan thought and soon understood the joints. The little Panther is one of the strongest races in the world. Even if he doesn't show up, the little Panther attached to him can still exude a powerful momentum. Although these poisonous insects have no IQ, their instinct has told them that they can't provoke these people.

This is just like when Yang Xuan was still in the forest outside Qingzhou City. Yang Xuan was weak at that time, but he was harassed by all kinds of insects and snakes, but he didn't encounter these things after meeting the little panther, but Yang Xuan's strength was still low and didn't find these things at that time.

Now when I think of it, taking the little Panther around me really reduces a lot of trouble.

"Xiaobai knows, Xiaobai knows why." Xiaobai, standing beside Yang Xuan, suddenly raised her hand and said to Yang Xuan. Yang Xuan was stunned, but then he put on a smile, turned to look at Xiaobai and asked, "then, Xiaobai, why don't these insects bite me?"

"Because you have a Tianxuan demon Leopard on your body. With his breath, other insects and beasts will not bite you again. Moreover, there is a very strange smell on your big brother, which makes me feel very kind, but I can't say what it is."

"Oh? You know Tianxuan demon leopard?" Yang Xuan was stunned. Before he was 16 years old, Yang Xuan had read a lot. In many legends, he had heard of all kinds of magical fierce animals, but if the little black leopard didn't tell him, maybe he wouldn't know the name of Tianxuan magic leopard in his life.

"Yes, I have recognized him since I first saw him." Xiaobai said triumphantly, as if waiting for Yang Xuan's praise.
