Huachen is a small country, the land area is not large, the area calculated by the current unit is only about 30 million square miles. Huachen Kingdom has a total of four corps, divided into central, southern, western, and northern divisions, and each legion has between ten and thirty corps. Among them, the Central Army has the largest number of troops, with 30 armies and more than 3 million people, which is directly controlled by the king, and is responsible for the garrison of the capital, maritime guards, mobile field warfare, counterinsurgency, and control of other legions; The other three corps were responsible for reclaiming the frontier and guarding the frontier in the south, west, and north directions.

The Shuangbang Mountains, the town of Beiguan, is the seat of the Northern Military Mansion. The Northern Army Corps has 20 corps, about 2 million people, distributed on a front of nearly 5,000 miles on the northern frontier, and its size is second only to the Central Army Corps.

When Bai Zhanyong and the others arrived at Zhenbei Pass, it was already five quarters of the day.

The city wall of Zhenbeiguan is as high as more than ten zhang, the radius is dozens of miles, the national flag of Huachen country and the military flag of the northern army at the head of the city are waving in the wind, the lookout platform in the city is towering into the clouds, black bricks, black tiles, black city gates, solemn and solemn. From a distance, Zhenbei Pass is like a fierce giant beast crawling there, ready to attack at any time.

Seeing Bai Zhanyong and the others approaching the city gate, the guards immediately greeted them, carefully checked the tokens they handed over, and then let them go.

Gongsun Yan followed Bai Zhanyong and them into the city, and found that the streets in the city were divided into primary and secondary, with a main road in the east-west direction and a north-south direction, which was as wide as two zhang, and there were bell and drum towers and lookouts at the intersection of the main roads. From time to time, patrols and law enforcement teams pass by on the streets.

Seeing Gongsun Yan's curious face, Bai Zhanyong introduced:

"The roads in this city are very complicated, in addition to these two main roads, other roads in the city extend to all sides like spider webs, dotted everywhere, the narrowest place only allows one person to pass, criss-crossing like a labyrinth, and the road is tortuous, deep, most of the end of the branch alley is the end, the broken road is closed, walking into a dead end, the roadside is full of hidden castles, perforations, all roads are in the shooting range, strangers go in only a dead end, if you come here alone, don't trespass!"

Seeing that the border city was so meticulously defended, Gongsun Yan was also amazed in his heart, and he nodded slightly in response while watching carefully.

The Military Administration Department of the Northern Military Government is located in the West Street of the Bell and Drum Tower, sits in the north and faces south, the eaves and arches are flying, the momentum is magnificent, the vermilion gate, the golden door nails, it is very magnificent. There were several armored soldiers guarding both sides of the door, and the surrounding walls were dense and the atmosphere was oppressive.

The six of them led the horses and quickly came to the door of the military administration. Bai Zhanyong asked the rest of the people to wait outside, and he took Gongsun Yan to step forward and salute the guards, show the military order and explain the intention, and the guards let them go smoothly.

Entering the hall of the Military Administration, a soldier immediately came to guide him, and the two came to the Legal Affairs Department according to his guidance, Bai Zhanyong handed over the official document sealed with fire paint handed over to him by Lu Xiance in Tishui Town, and a deacon opened it and read it, and immediately sent the document to the Medical Affairs Department, asking them to go to the Medical Affairs Department to register and make a register and handle the official documents for entering the camp.

After a while, the two came out to meet the people, and they led their horses to the north gate quickly, and it was sunset when they walked out of the gate. The Bingyin army barracks was still dozens of miles away from Zhenbei Pass, and the six people got on their horses and galloped in the direction of the barracks.

Outside the north pass of the town, the mountains are barren and the forests are sparse, the grass and trees are withered and yellow, the autumn wind is bleak, the twilight is desolate, the horse is galloping, and a group of slaughtering scenes are coming. Gongsun Yan sat on the back of a horse behind Bai Zhanyong, and as far as the eye could see, on the rolling mountains, tombs were sitting there lonely, overgrown with wild grass. He couldn't help but sigh in his heart: on this ancient battlefield, countless people buried their bones in horse leather and yellow sand, and the tomb is not only the place where the bones of heroes are buried, but also the hope of countless families and parents and the lovesickness of wives and children.

The Bingyin military camp to which the Northern Army belongs is located at the foot of Tianmen Ridge Mountain in the South Python Mountain Range of the Shuangbo Mountains. The Shuangmang Mountains are the branches of the Fengqi Mountains, starting from the coast of Qingzhou in the east and ending in the territory of Xiasu in the west. The Twin Python Mountains are actually two nearly parallel mountain ranges, consisting of the Southern Python Mountains located in the territory of Huachen Country and the North Python Mountains located in the territory of Rampant Yuan Country, most of which lie across the border of Huachen Country and Rampant Country and are a natural barrier between the two countries.

The six of them came all the way, and when they arrived at the barracks at the foot of Nanpython Mountain, it was almost dusk. When there are still fifty zhang away from the barracks, everyone turned over and dismounted, led the horses in a line, and at five zhang away from the camp gate, Bai Zhanyong took out the arrow and Gongsun Yan's official document to enter the camp, and the five people all showed their waist cards, and after the gate guard checked it, he signaled that everyone could enter.

After entering the camp, the others left after greeting Gongsun Yan, and Bai Zhanyong took Gongsun Yan to the military administration office to hand over orders, register and make records, receive waist cards, and then report to the military medical office.

A quiet place in the depths of the barracks where the Bingyin military doctor is located, Gongsun Yan followed Bai Zhanyong through the barracks, there are basically no soldiers walking on the road, there are sentinels in front of each barracks and at the intersection of the intersection, the whole barracks seems to be calm and silent, during which the patrol team will occasionally be encountered, the two show their waist cards and explain the situation and immediately let them go, Bai Zhanyong also briefly introduced the military discipline and some basic information of the barracks to Gongsun Yan while walking, Gongsun Yan silently remembered them one by one.

The two walked all the way, and soon saw several rows of white board houses with fences under the jungle, which were particularly dazzling at dusk, and there were sentries standing guard at the gate of the courtyard.

"Captain Bai Wu is here for something?" The barracks to which the military doctor belongs, under normal circumstances, are not allowed to enter.

"Well, it's Ding Wei, I brought him to report for duty." As he spoke, he pointed to Gongsun Yan, and after checking the waist cards of the two people, the sentry immediately let them go.

Bai Zhanyong led Gongsun Yan to the front row of houses, and as soon as he entered the door, he met a man in his twenties with a white face, Bai Zhanyong immediately said:

"What a coincidence, Doctor Gongsun, your brother is here," he pointed to Gongsun Yan beside him and said:

"In the future, your brothers can be more close together," and said to Gongsun Yan: "This is your eldest brother, Dr. Gongsun Xian." ”

When Gongsun Yan heard this, he hurriedly saluted and said, "Junior brother Gongsun Yan has seen the eldest brother."

Gongsun Xian's face was cold, but he nodded indifferently, "oh".

Seeing this, Bai Zhanyong hurriedly asked again, "Is Duanmu Medical Officer here?" ”

Gongsun was silent, pointed to a room in the hallway, and brushed away.

Bai Zhanyong and Gongsun Yan looked at each other and smiled bitterly, and led him to the door of the room, Bai Zhanyong stood up and saluted:

"Report to the chief, Bai Zhanyong, the commander of the ninth squad of the Bingyin Army, escorted Gongsun Yan to report to duty."

Gongsun Yan's heart suddenly tightened when he heard this, and his face turned pale in an instant, everyone treated him very well all the way, making him almost forget his identity.

There was no movement in the room, and after a while, a hoarse voice came out: "Come in!" ”

Gongsun Yan lowered his head and followed Bai Zhanyong to push the door and walked in.

The person in the house is Duanmu Xianjun, the medical officer of the Bingyin Army, the Duanmu family is another major medical family in Huachen Kingdom, although the reputation is slightly inferior to the Gongsun family, but its family power is also all over the country, and there are also people who serve as imperial doctors in the palace. At this moment, Duanmu Xianjun was sitting upright next to a desk, his originally clear face was slightly gloomy, and when he saw them come in, he glanced at the two of them, and then waved his hand at Bai Zhanyong:

"There's nothing to do with you here, you can leave!"

Bai Zhanyong was just a small army commander, and his status in the army was far inferior to that of a medical officer, so he answered "yes" and turned around and left quickly.

There was silence in the room for a while, and Duanmu Xianjun suddenly shouted:

"Gongsun Yan, are you guilty?"

Gongsun Yanmu lowered his head and did not make a sound.

Duanmu Xianjun continued: "Don't think that you can get away with silence, you are the son of a criminal doctor, a pawn, your father ganged up in the army, engaged in personal fraud, and openly opposed the Shangguan general, did not remember the king's grace, disregarded the interests of the country, and killed the mighty general in order to vent his personal anger, although he died of fear of sin, but the crime is unforgivable, the so-called father's debt is repaid, and you have to bear the consequences of your father's crimes one by one!" ”

Although Gongsun Yan had been mentally prepared for these various "crimes" imposed on his father, he still underestimated Duanmu Xianjun's shamelessness and viciousness. Now that my father has died, I let him talk nonsense.

"You are from a family of criminal doctors, you must be branded as a criminal family, since you are here, you should be a miscellaneous soldier first, and you must be an honest person in the army in the future! Do things in a proper way! Don't talk nonsense! If you can repent and reform yourself, and make meritorious contributions, this official will not give you a chance, so you can do it yourself! After speaking, he waved his hand to Gongsun Yan as if impatiently.

Immediately, he rang the bell and called for medical assistance to take Gongsun Yan out.
