The battle on the border of Yan and Zhao was in full swing, and the army of Zhao State encountered the powerful Donghu cavalry, which was called Yan Zhao Gate in later generations.

Zhao Kuo took the method of feint attack in the middle to attract the main force of the Yan army, and the siege elite on both sides was sent to capture it in one fell swoop, and then posed a threat to the middle road, there was no mistake in the tactics, the king of Yan and the old enemy Donghu united also beyond Zhao Kuo's expectations, if the Zhao army is a tiger, Donghu must be a fierce wolf, once Zhao chooses to retreat, the Donghu army takes the opportunity to attack the Yan camp, the consequences can be imagined, the king of Yan also has scruples, this time to participate in the battle is the main force of Donghu, the elite of Yan is arranged in the rear to wait.

Behind the Biansai, in the land of Yan, a team of people and horses gathered, and the leader was a black-faced man, with a long sword next to him, and his voice suddenly stood up from the ground, "It's bad, the news of the blockade of the Biansai can't be sent, and now the king is facing not only the Yan army but also nearly 200,000 Donghu elites, this battle is not good." ”

Why did Zhao appear in the territory of Yan State, in order to find out the truth and truth, various countries have sent spies, and the identity of the spies is extremely secretive, especially Zhao State, Zhao Kuo has worked hard to establish a special camp, not only is he absolutely loyal but also has mastered various fighting skills, and the alliance between them completely relies on passwords.

The black-faced man was originally a butcher in Jicheng, and the business was not bad, because people looked black, commonly known as black butchers, of course, it was just a joke, never short of catties or two, and the location of the meat stall was also close to the main city road of Jicheng, and the main city road led directly to the royal city.

"It seems that there are a lot of big people today!"

The official sighed and said, "These lords are difficult to mess with, and the distinguished guests invited by the king. ”

"Distinguished guest, it doesn't look like a person from the Central Plains."

"Hu Ren!"

"Why did the Hu people come here?"

"It's not that Zhao Ren made trouble, don't talk about it, someone will send you money when you come back."

"Forget it, just honor your lord at that time."

When the official left, the black-faced man turned around and stepped aside, took out the black charcoal burned on the ground and quickly drew a few strokes on the wall, some similar to children's graffiti, but in fact, only his own people could understand the meaning.

Like night, bangbangbang, knocking on the door, the butcher opens the courtyard door, from time to time someone enters, quickly connects the code to determine the identity, there are thirty people, there are meat butchers, street hawkers, and people run errands to make a living, some simply blend into the official's mansion to be a subordinate, no matter what, no one dares to forget their own mission, Zhao Guo's secret agent.

The Black Butcher signaled, and someone saw a quick departure, almost all marked in a conspicuous location.

"Since everyone is here, I simply made it clear that the king Xingbing has been like a bamboo, and now he is at odds with Yan, and now there are Hu people in the thistle, it should be in collusion with Yan."

"Colluding with foreigners has lost the face of our ancestors."

"It's not important anymore, it's how the message gets out there."

"This is easy to do, you and I are both merchants, go out of the city in turn tomorrow, and find an opportunity to go out of the border to inform the king."

"It shouldn't be that simple, I overheard the adults mention that King Yan ordered the blockade of the borderlands, and it must not be easy to get out."

"You have to try, and you'll leave tomorrow."

After the discussion, everyone left, the black butcher opened the door and came to the front, in order to disguise his identity, he simply married Yan Nu, and he had early feelings for a few years, and he didn't know if he could go back when he left today, and he couldn't help but sigh secretly when he thought of this.

"I'm going to go to market tomorrow, why don't you sleep?"

"If you have something to go out, the affairs of the family will be handed over to you, and if you don't come back after a long time, you will find another home."

"What nonsense, I'm sleepy."

The woman turned over and fell asleep, most of them didn't take it to heart, the sky was bright, the black butcher was dressed neatly, bent down and took out a bag from under the bed, opened it carefully, there was a bright and dangling long sword inside, the sword body was much longer than the ordinary long sword, the blade was sharp, unique to the swordsman of Zhao State, and had not been used for many years.

"It's so early!"

The soldiers defending the city recognized each other and greeted each other, the black-faced man raised his wrist, and the soldier grabbed it in his hand, "Give a few drinks to my brothers." "The soldiers who defended the city smiled, two pig kidneys, this is a good thing.

"Thanks!"

The domestication of wild boars, and then raising to provide meat has long been recorded, and it is also a feat of human beings, the Donghu people feed on beef and mutton, and the Central Plains people prefer pork.

The butcher went out of the city, came to a remote place, unloaded the bamboo basket, took out his clothes from it, quickly changed them, grabbed the long sword in his hand, spread his legs, and went straight to the side.

The border land is under martial law, no one is allowed to enter or leave, and the king of Yan also knows that once Zhao Guo learns the news of the Donghu army, he must be prepared, so it is not good for himself, so he immediately ordered, if he dares to let go of a person, he will not be spared, and the border guards will not dare to be careless, and send more troops and horses to completely control the border along the border.

"If you find out, you can't get over it at all."

The spies of the Zhao Kingdom regathered, there was no shortage of thirty people, and no one flinched in the face of danger, "How many people are in a team?" ”

"There should be no less than fifty people!"

"Let's get rid of one first."

"Big brother stays here, I'll take someone to do it."

"Be careful, after the thing is done..."The black-faced man admonished, more than a dozen people left quickly, the sky became darker and darker, footsteps sounded, and everyone clenched their long swords.

"It's your own people!"

There were people guarding the high places, and they could see the identity of the other party clearly by the moonlight, and a group of more than ten people quickly returned, holding the unique clothes of the Yan Army in their hands, and it is unknown what it was for.

"Big brother, it's solved."

"Well done, change it immediately, I just hope to be able to mix up the side plug."

In the Yan army camp, the main general got the news that a team of peripheral patrol soldiers lost contact, and each camp changed positions at an hour, the purpose was to form an effective connection between each other.

"If you encounter someone who doesn't understand the password, you will be killed!"

A team of soldiers from the Yan Kingdom approached, and a group of soldiers also came to the opposite side, led by a black-faced man with a straight body, "Eagle in the night!" The opposing camp suddenly issued a command, and the black-faced man was stunned, the eagle of the night, what is this, is it a dialogue or a temptation, or there is something else implied in it.

"Spread your wings and soar!"

One person dealt with it casually, the man was also stunned for a moment, waved his hand, the camp turned, and the man said in a low voice: "This is okay, Yan Ren is really a pig." ”

"That's not right."

The black-faced man seemed to think of something, after a few days of observation, these people should be going to replace the patrol area under their control, why did they leave directly, just now the other party leader had a strange expression on his face.

"Let's go!"

The torches were lit immediately, and the two teams of Yan troops rushed up quickly, before they left the team and returned quickly, and they had already guessed from the other party's password that someone must be pretending, so they deliberately delayed, and happened to meet another team, and the team was close to 100 people, so it was enough to return immediately.

"Rush out."

The spear raised and everyone rushed out, the strength of the wheel was far above the soldiers of the Yan Kingdom, and a bloody path was quickly disappeared into the night.

"Waste, it's all waste." The Lord will be furious, and he will almost let people get away with it, and then the king will blame himself for his own life.

"General, those people are very strong, and with our clothes, this is the most difficult to prevent."

The Lord General nodded, "How many people are on the other side?" ”

"Thirty or forty."

"This is easy to do, the patrol battalion strength has increased to two hundred, and if you encounter a small number of people, you can do it directly."

In the recess of the mountain, everyone sat on the ground and gasped for breath, and escaped by luck after a fight, but fortunately, the Yan army camp did not form an effective defense, otherwise it would not be easy to rush out.

"Big brother, what now?"

"If you want to get out, you can't do it, you can only wait for the opportunity."

The army of Yan and the Donghu cavalry approached the fortress, and all of them were controlled by the Yan army within a few miles along the way, and the main general did not dare to mention the events of the day so as not to anger the king of Yan.

On the periphery of Yan Jun's control, a hidden cave revealed everyone's figures, and two months passed, but they never found an opportunity, and could only watch the Donghu army enter the fortress.

"What a nonsense!"

"It should be no less than 200,000." The black-faced man clenched his fists, as the leader shouldered heavy rules, the news could not be sent to force the army of Zhao to fall into a predicament, so worthy of the king's trust, how to do it.

"What now?"

"It's better to set it on fire, the king may be able to guess when he sees it!"

There are several different ways to transmit messages between spies, lighting a beacon fire is the most common one, someone invented something that can rise into the sky, as long as it is pulled and exploded in the air, it can be heard from a distance and can be seen.

"No, the place where the periphery can hide is already limited, not to mention that now that Yan Country is spring ploughing, many people use fire to light firewood and grass, even if the scale is formed, it will not attract attention."

"Something should be done."
