The night was dark and the wind was high, and agile figure quietly touched the head of Yi Jing in the night, and hid the patrol soldiers all the way and touched the outside of the city.

Yijing was vast, and although the Yuan army who was sieging the city could not surround the city, the soldiers guarding the city could not imitate it. Because the length of the outer wall was too long, one patrol soldier could only be set up every fifty steps.

After Yuan Jun dug the tunnels on a large scale outside the city, Gongsun Zan drew some soldiers down the city wall and patrolled the streets and alleys in the city to prevent Yuan Jun from entering the city suddenly from the tunnels. This made the defense on the city wall even weaker and reduced to one hundred steps per person.

One hundred steps to one person's defense force, monitoring the army under the city's siege, has no problem. When the attacking party approaches the city, it can beat the war drums, blow the horns, and alert the people of the country. But it is a bit powerless to those scouts with unique skills in climbing the wall. These people are as elusive as ghosts in the dark, making people unable to defend themselves, going in and out of the city wall and spying on intelligence.

With the cover of night, the man in black quietly approached a battlement at the city wall, took out a rope with iron claws from his arms and hooked it on the battlement, and then pulled the rope five or six feet long down the city wall, grabbed the rope with both hands and slid down the city wall...

After landing, the man in black smiled contemptuously at the defenders on the city wall. Such a defense intensity was OK to monitor a large number of siege troops, but for a scout like himself with unique skills, it was useless.

He shook the rope vigorously and pulled the iron claws and ropes down one by one, but because he was too careless, the iron claws accidentally landed on the ground, making a "clang" metal sound.

"No, there are spies under the city!"

After all, the defenders on the city were not deaf, so they immediately found someone under the city wall, shouted and called on their companions to come for support. Immediately, several soldiers from the nearest gathered over, shook the torches in their hands, and fired arrows under the city.

The man in black ran away, faster than a rabbit. A few rabbits rose and fell and came to the moat. He jumped, got into the cold river water, and then disappeared from the water...

"Where are people, where are people?"

More than a dozen defenders had gathered on the top of the city, and torches were swaying. They looked down at the city, but they could no longer see the figure that had just been made. They could only shoot a few arrows in the water.

A figure under the water swam a hundred feet like a fish, exposed her head at another place, and then climbed to the shore as fast as possible. Amid the screams of the soldiers on the city wall, they ran towards the Yuan army camp in the distance. The soldiers on the city wall wanted to shoot down arrows again, but the range was too late, so they could only do anything to do and were in a mess.

"General Qi reported to him that he had caught a man in black outside the camp. He claimed to be a scout who served you. He came to deliver important information. I don't know what to do?"

Yuan Mai was sleeping soundly, woke up by the report from the guards outside the door, and got up. He guessed that the person who came was mostly a detailed work under Zhen Yao, and probably had spyed on the place where Zhao Yun was imprisoned.

He hurriedly put on his clothes and ordered: "Take me quickly!"

Not long after, a man in black and soaked all over was taken into the camp. After seeing Yuan Mai, he bowed: "The villain is Cao Qian, the number one scout under Zhen Erye, and has already spied at the place where Zhao Yun is detained as ordered. I will deliver the letter!"

"Well, it's not bad. Under such a tight defense, you can still come and go freely. You are a talent!"

Yuan Mai was very happy when he heard that he had spied Zhao Yun, and patted Cao Qian on the shoulder, praised him a few words, took out a ingot of silver from the box on the hand, and stuffed it into his hand, "Thank you for your hard work, I'll give you this! Take the map over and I'll take a look, and let the soldiers take you to change your clothes!"

Cao Qian took out a kraft paper bag from his arms, and the map he made was put inside. The outer skin could be used to prevent the map from being soaked in water.

He spread the map on the table and didn't bother to change his clothes. He introduced to Yuan Mai: "Please look, General. The villain painted this map for half a month before it was made. It marked the place where General Zhao Yun was imprisoned. In addition, I also spyed on several important granaries of Gongsun Zan, and all of them were marked in the picture for the young master's reference and decision-making!"

Yuan Mai glanced at the map and saw that the production was very exquisite, with all the barracks and granaries in the streets and alleys, all of which were marked. It was really a rare weapon to siege the city. With it, it was clear about the layout of the city and played a role in getting twice the result with half the effort!

"Not bad, not bad... really good!"

Yuan Mai liked the map the more he looked at it, and praised him: "It seems that you are indeed a talent. I will tell Zhen Er, just do things under my command. Sometimes I also need an excellent scout to complete the task! If I had an outstanding talent like you, the letters I wrote to Zhao Yun would not have been caught!"

"Thank you for your kindness to support me. I am willing to serve you as a child!" Cao Qian knelt down and thanked him, and then followed the soldiers to change their clothes.

The next day, Yuan Mai picked a thousand people from his soldiers and asked Cao Qian to lead the tunnel to dig, a prison leading to the detention of Zhao Yun, so that at the right time, he would rush out of the tunnel to rescue Zhao Yun, and dig a few more tunnels leading to the major granaries.

According to the development of history, after the city gate was broken, Gongsun Zan, who was at a loss, killed his wives, concubines and children, set fire to the mansion and granary, burned the city's property and turned into ashes. Since Yuan Mai predicted the unexpected and knew the result in advance, he would do his best to keep the food and grass, and be able to get one stone more!

Life passed quickly, and in a blink of an eye, four or five days passed. It was already mid-March, and the weather gradually became warm.

The tunnels outside Yijing City were dug up and were devastated, like rat holes in the fields, densely packed, making it impossible for the defenders on the city to tell which one was real and which one was fake? With the sound of "ding Ding Dangdang", several tunnels had been chiseled into Yijing City, waiting for the right opportunity to break out of the ground and launch a surprise attack.

On the city wall, I saw that Yuan Shao's nearly 100,000 troops did not come to attack the city, and only dug tunnels outside every day. This made Gongsun Zan feel so angry that he didn't dare to go out of the city to fight the decisive battle. He climbed up the built platform every day and looked west, waiting for reinforcements to arrive.

One night a few days later, Gongsun Xu's envoy forcibly broke through and rushed into Yijing City, bringing intelligence to Gongsun Zan. Zhang Yan, the general of the Central Army of the Punishment, gathered 100,000 Heishan Army, divided into three groups, and was advancing towards Yijing. It is estimated that it will arrive in less than a few days. Please wait for the reinforcements!
