Jicheng, which was once the capital of the Yan Dynasty, has been operated by the Yan royal family for nearly 100 years, not only with wide city walls, but also with an extremely grand building scale. And in terms of defense facilities, it has its own uniqueness.

Beyond the Yanshan Mountains, the northernmost part of the Yan Kingdom is the border with the grassland, which has been repeatedly invaded by the Hu people. At the most dangerous time, the vanguard of the Hu people's iron cavalry had even approached under Jicheng. To this day, there are still traces of iron arrows left on the north city gate.

The Yan royal family, which is facing threats at any time, can be said to have spared no effort in consolidating its own security. In order to strengthen this fortified city, it did not hesitate to spend a lot of manpower and material resources to achieve today's scale. It's just a pity that although it blocked the hooves of the Hu people, it did not avoid the disaster of the country's demise after all.

Since the land of Yan was returned to Zhao, the defensive position of this famous northern city has been greatly weakened. Because according to the theory of Zhao Wang Chu Jiangmian, the idea he instilled in his soldiers has always been "the best defense is offense"!

Instead of spending money and money building cities and walls, it is better to use all these efforts to strengthen the combat effectiveness of the army. And the facts that have passed through the past few years have proved the correctness of his thinking. Zhao Jun complied from top to bottom. As a result, even though the country's financial resources have been greatly improved, these military defense aspects have been used very little. Even an important border city like Jicheng is basically the same as before, and it hasn't changed much.

Perhaps, for this reason. It was only then that those who were lurking in the shadows thought that they had an opportunity. When a once-in-a-lifetime opportunity came, they didn't hesitate to get into the action.

After dark, the General's Mansion seemed a little quiet. In the battle for several days, the general has been standing on the head of the city to personally supervise the battle, and the soldiers have seen it in their eyes and felt pain in their hearts.

In the minds of the 80,000 defenders of Jicheng, the general Li Mu is their spiritual pillar. At present, his physical health is undoubtedly the top priority. Therefore, when the fighting stopped a little and the general returned to the palace to rest tonight, all the people in the palace became cautious and tiptoed. lest there be any big movement that will affect the general's rest.

And the soldiers who were on guard outside and around the General's Mansion were also on duty dutifully. In order to ensure that the general rests well, several surrounding streets are strictly forbidden to pass, and no one is allowed to approach casually. These are special times, and naturally no one will complain about this. The people of Jicheng know very well that General Li Mu is responsible for the defense line of Jicheng with his own safety, and as long as he sits in this fortified city, the Hu people will not want to take a step south. This is everyone's trust in him, and it is also where his prestige lies.

It's the beginning of the month, and after nightfall, the half-quarter moon hangs diagonally in the dark inky night sky. The stars are sparse and the sky is lonely. The moonlight falling on the world is even more pale and cold.

Just after the second watch, most of the people in the city had already fallen asleep. Occasionally, a patrol soldier passed by, swords colliding with iron armor, making a golden sound. Outside the city, the sound of the long neighing of war horses came in from afar, always reminding people that this was a battlefield where hundreds of thousands of armies clashed, not a place where they could sleep soundly.

Suddenly the wind rose, and the fallen leaves were silent. There is a dark shadow that falls to the ground along with the leaves. The young man in a strong suit and sweating profusely discerned the direction a little, and quickly walked along the street towards the General's Mansion.

The young man's name is Fox Nine. His true identity is just an ordinary Thousand Machine Pavilion spy. The reason why he hurried back to the city in the middle of the night, over many obstacles, was because there was a hundred thousand urgent news that needed to be reported to the general immediately. In order to find out the truth of this news, three of the spies lurking among the Hu people died. And the reason why they do not hesitate to reveal their identities is only because the stakes are so high that they cannot be negligent at all.

Fox Nine was the only one who came back to report the news. He was anxious along the way, fearing that if he came back late, something bad would happen. However, after entering the city and seeing that the city was calm and there was no sign of chaos, his heart finally settled down a little. Even so, they did not dare to delay. Perhaps, only by rushing to the General's Mansion as soon as possible and letting the soldiers in charge of vigilance be as vigilant as possible, he can be completely relieved.

The situation on the battlefield is changing. The battle between the secret forces of the two sides is even more intense. Although most of them are unknown, the difficulties in this are not inferior to the charge on the battlefield.

Although Hu Jiu is young, he is an excellent spy and has a lot of experience. At such a critical juncture, he did not dare to trust anyone easily. There are some things that can only be avoided by telling General Li Mu or the people around him in person.

The General's Mansion is here in a blink of an eye. With his skills, it is not difficult to sneak in quietly. Although this is a bit inappropriate, in such an emergency, there is not much to consider.

He had been to the General's Mansion a few times before, and he generally remembered the directions. Therefore, I tiptoed and approached the backyard smoothly. The resting place of General Li Mu should be in these rows of courtyards.

It's a pity, though. As soon as he entered here, his whereabouts were immediately discovered. Two knives pressed against his body, one behind the other, and someone whispered in his ear.

"Put the knife down, don't act rashly."

Without saying a word, Hu Jiu took off the knife from his waist and threw it to the ground. He knew very well in his heart that while the blade was against him, there must have been sharp crossbow arrows blocking all his retreats in the distance, and it was more difficult to escape than to ascend to the sky. However, he did not panic. I didn't plan to run away in the first place. The reason why he entered the General's Mansion without wanting to alarm people was also for the need to be cautious. Since it has been discovered, it is good to explain it generously.

It's just that Hu Jiu didn't expect it. He had just said a few words, but before he could explain, the person in charge immediately stopped him. Then, the man winked to the left and right, and two pairs of strong arms firmly bound his body, dragging him to the side.

Fox Jiu immediately realized that something was wrong. Someone in the General's Mansion dares to do this, obviously with bad intentions! Thinking of the news that he had given up his life to spy on the Hu people, he immediately struggled desperately, trying to break free and get his knife.

However, the person next to him is clearly a master. With just a light blow on the back of his neck with a knife, Hu Jiu was paralyzed, not only was he powerless to struggle, but he couldn't even shout out of his mouth. He could only watch as he was dragged away from the general's residence, and his heart was full of regret. If even these people in the General's Mansion are in collusion with the enemy, then it will really be a big deal! It's just that no matter how much he regrets it, it won't help.

The backyard of the General's Mansion returned to calm, and the small change that had just happened barely made a single movement. In the room where the general usually rested, the attendants had already turned off the lights for him early, and it was a little dark. A few lanterns in the courtyard swayed in the wind, and night was enveloped all around.

I don't know how long it took again. About three days ago, almost without warning, under the steps on the left side of this courtyard, someone suddenly lifted the ground and came out from under the ground. The black-clad figure scanned left and right, and sure enough, he didn't find any shadows of guards or armor. He smiled coldly, then gestured behind him, and then more than a dozen figures came out of the place where he had just appeared.

It's clear that these people are already familiar with everything here. They have a clear division of labor and are very agile in their actions. In the blink of an eye, he sneaked into the darkened room. The clouds cleared, and the moonlight illuminated the cold glow that flashed in their hands. Everyone had drawn their swords, several men were on guard at the doorway and outside the window, and the most powerful killer among them had turned over and taken his target!

There seemed to be a slight noise in the room, a flash of knife. Then, the man in black who had gone in immediately came out. Through the moonlight, it can be seen that one of them is carrying a bloody head in his hand! Obviously, this is what they just hunted.

"Li Mu is dead! Hurry up and retreat!"

In the confusing light, someone whispered only these few words. All of them took the head, put away their swords, and quickly disappeared under the steps. The breeze blows, and the fallen leaves drift away. Everything seemed silent, as if nothing had happened.

And in the second half of the night, when the wind suddenly rose, the general's mansion finally discovered the abnormality. As someone's panicked shouts sounded, the entire General's Mansion was lit up one after another, and it began to fall into chaos.

Soon, a shocking piece of news spread. The General's Mansion was raided by assassins at night, and General Li Mu was unfortunately killed! Before dawn came, the city was full of crying.

Hu Jiu, the spy of the Thousand Machine Pavilion who was temporarily imprisoned in the courtyard next to him, had just slept groggily because of the fatigue of the day. He was awakened in his sleep. Hearing the faint cry, his face immediately turned pale.

"What happened? Let me out...... You bastards! If the general has any grievances, I will definitely go to King Zhao in person to seek justice!"

Hu Jiu struggled, and while banging hard against the thick wooden door, he was already angry and scolded. But no one paid attention to it, and the armor soldier who was in charge of guarding him was like a wooden clay sculpture, just looking at him with a blank face, and the expression on his face was very indifferent.

Exhausted, Fox Jiu had no way to escape. He sat down on the ground again, clutching his head in pain with his two hands, muttering to himself.

"It's over...... If General Li loses, Jicheng will not be able to be saved...... The 80,000-strong army and the northern defense line are in danger!"
