There are only ten large and small cities, which are concentrated in the south of the territory of 200,000 square kilometers, because the south is close to the sea, and the climate has four distinct seasons, which is suitable for living and farming. The name of the northernmost city in Yan Kingdom is very similar to its geographical location: Guzhu. Like a lonely bamboo on the vast land, it seems particularly lonely and abrupt, the original lonely bamboo goes north to the north is a vast grassland, the Beidi people and the Yan people have been fighting back and forth on the grassland for many years, and suddenly one day the appearance of the Qingtian God Mountain broke the precarious balance between the two groups of people, and the grassland that gave horses, cattle and sheep infinite nourishment became extremely dangerous, full of hidden swamps and deep holes, people and livestock accidentally fell into it, except for the senseless struggle, that is, to quietly accept the embrace of death. In this dangerous grassland, the Beidi people lost their mobility to come and go without a shadow like the wind, life became more and more difficult, a group of people chose to submit to the Yan country, after all, the war for many years, both sides have plundered prisoners, some good-looking female captives naturally undertake the task of breeding, in the lonely bamboo can often see children with the characteristics of the Beidi people, their attitude towards the Beidi people is more tolerant than the previous generation, the two sides have been fighting for so many years, many customs are also intertwined, Therefore, the Beidi people who chose to return to the Yan Kingdom quickly adapted to the new life, after all, the comfortable life of farming and grazing is safer, and they don't have to worry about losing their heads one day. The other part of the stubborn people proved with great courage and perseverance how strong their faith is, they walked through the dangerous grassland, approaching the Optimus Divine Mountain, on the one hand, they believed that it was the divine revelation, and the appearance of the Heavenly Divine Mountain in the place where their ancestors had lived, it was some kind of revelation from the gods, they wanted to find out what the ancestors wanted to convey, and on the other hand, they had to climb over the Heavenly Divine Mountain to find a new place to live. Both goals seemed difficult to achieve, but they did it anyway and never returned. Only this lonely grassland is left, and the scenes of the fight are recalled every day.

In order to avoid the tracking of the envoy of the Yan Kingdom, Wu Daoxuan and Wu Yong chose this remote route, and they could not see a single person on the road every day, only the birds in the sky and the reptiles on the ground were with them. Wu Daoxuan didn't care about this kind of isolated life, sometimes in order to paint, he would often stay alone in an inaccessible place for a month or two, and he preferred this simple life to socialize with people. Wu Yong was originally relatively taciturn, after being caught by the resentful spirit, his temperament was even more indifferent, he didn't say a word for three or four days, the two walked together for many days, Wu Yong didn't ask where to go, he caught a few beasts and birds when he was hungry and roasted them and ate them, and when he was thirsty, he drank some stream water, and with the ability of the two, it was not a problem to survive in the wilderness.

On this day, they traveled on the edge of the grassland for many days, and finally saw a big city, the traces of the fierce battle can be seen on the lonely bamboo city wall, even now, there are still very few Beidi remnants on the grassland, seeking life in the narrow gaps, they did not follow the tribe to the north to find the destination of faith, nor did they have a blood feud with the Yan people, stubbornly follow the life that the nomads should have. Therefore, Lone Bamboo City still retains wartime facilities and armaments to deal with the more ferocious and cunning remnants of Beidi.

Wu Daoxuan and Wu Yong, two obvious Central Plains people's appearances, did not attract more attention, and easily entered the city. Chose a fairly good inn in the city to live in, Wu Yong found that Yan Guo was far less rich than Jin State, and even in a big city like Guzhu, the inns and residences in the city were obviously old. Wu Daoxuan said: "Don't you wonder why there are only ten cities in the Yan Kingdom, and the lonely bamboo in the independent north is so poor?" ”

Wu Yong nodded.

Wu Daoxuan said: "The 10,000-mile city wall of Yan State has cut off the road with various countries, and also covered up a lot of things, in fact, Yan State's products are not less than those of other countries, and even fisheries and animal husbandry have won, but too many resources have been taken away by the army, and the number of troops collected by Yan State is almost equal to that of Qin State, and the average two farmers raise a soldier, and the quality of armaments is also superior in all countries." This Yan Zhaogong, his mind is far beyond the city wall! ”

Wu Yong followed Wu Daoxuan's sigh and also looked into the distance, which was the direction of Jicheng, the capital of Yan Kingdom.

As night fell, Lonely Bamboo City quickly entered the time of rest, only a few lights were still lit in the mansions of some officials and clansmen, and the rest of the houses were completely dark, and even the inns operated by tourists were closed early. Wu Yong slept on the bed, listening to the wind blowing from the grassland outside the city, as if he could touch the grass that was blown down by the wind. Wu Daoxuan stood by the window, looking at the bright moon, which seemed to be bigger and rounder than that of the Jin Kingdom.

"Want to see the grasslands?" Wu Daoxuan asked suddenly.

"Okay." Wu Yong was still reluctant to say one more word.

The two of them didn't change their clothes, gently pushed open the door, Wu Daoxuan flew to the roof from the patio like a feather, Wu Yong stepped on the guardrail, jumped up and followed, and also did not make any sound. Although the night light was very good, most of the lonely bamboo people who were accustomed to a boring life had already returned to the house, and no one saw the two figures, one after the other, drifting out of the city.

There is a distance between the buildings in the city and the city wall, which is reserved for the passage of chariots, horses and city defense equipment, Wu Daoxuan did not make any stops, suddenly accelerated, like an arrow shot, instantly jumped from the roof to the wall, and the soldiers patrolling on the top of the city wall did not find any trace at all.

Wu Yong's whole body was wrapped in a rich black gas, like a wisp of rising smoke, and he followed Wu Daoxuan to the wall.

The silence of the grassland at night was lively, Wu Yong could hear the breathing of the insects perched under the grass, and he could also hear the sound of countless grasses bowing their heads when the wind blew. Wu Daoxuan took Wu Yong on the grassland, running wildly, for a moment, Wu Yong felt a sense of déjà vu, as if there was a time when he also ran heartily on the grassland like this, but he couldn't recall the details at that time. Soon, the two galloped out of more than ten miles and entered the depths of the grassland. For ordinary people, even if they want to pass through this grassland during the day, it is dangerous, but like Wu Daoxuan, even if he is a few levels inferior to Wu Yong, he is not afraid of the swampy sinkholes that can be seen everywhere at all.

Suddenly, a bright light flashed in the distance, Wu Yong had already found that at night, his eyesight was exceptionally good, even farther than during the day, and some of the scenes were not seen clearly through the light projected into the eyes, in other words, Wu Yong felt that the night also had its color, and he could see many things clearly without light. The light in the distance was the moonlight reflected by the weapon, and there were people on the grassland.
