Zheng Anping judged that the people on the other side must have been waiting for most of the day, and when they saw that no one was coming, they were ready to collect their troops and go home. He looked at the sun, if it sank a little westerly, the depths of this canyon should not be able to shine in the sun, and he could rely on the cover of the mountain shadow to move forward boldly.

He said what he thought, and the doctor said that he was willing to go down to control the troops, leaving Zheng Anping and Chen Si to observe on the mountain. The two sides agreed on the contact information and code, and the doctor went down the mountain. Before long, the doctor began to shake his halberd, on which hung a battle robe; Zheng Anping had also taken off his battle robe and hung it on the halberd, and now he shook his halberd in response, and the contact code between the two sides was connected. Zheng Anping saw that the time was about the same, and there was no one on the opposite mountain, so he stuck the halberd vertically on the top of the mountain beside him, and the halberd under the mountain shook, and he saw the halberd hanging on the robe moving forward. Although Zheng Anping was very close, if there was such a halberd, he couldn't see the movement of the soldiers below. This made Zheng Anping very satisfied. So Zheng Anping insisted on the halberd, Chen Si was mainly responsible for observation, and the two also ran forward alternately along the hillside and moved to the next observation point. When he arrived at the next observation point, Chen Si introduced to Zheng Anping what he had observed, and then instructed another observation point, and he ran to that observation point. Zheng Anping still stuck the halberd by his side and observed forward attentively, and the halberd below was also rapidly advancing. Chen Si observed for a while, then turned around and beckoned; Zheng Anping also picked up the halberd and ran to where Chen Si was.

In this way, they had moved forward, and after about an hour, they had advanced nearly ten miles. The canyon that had just been occupied by the crowd was already in front of me.

Taking advantage of the sunset, Zheng Anping did not see anyone at the mouth of the canyon, and they had probably withdrawn. Chen Si also became cautious, bent over, lowered his body and ran forward. Suddenly, Chen Si fell to the ground and turned his head to make a gesture at the same time. Zheng Anping immediately put down the halberd, raised it again, shook it, and put it down again. The halberd under the mountain also shook it to indicate that it had been received. Zheng Anping gestured to Chen Si and asked if he could go up, and Chen Si responded with a gesture, yes. Zheng Anping bent on his waist, cautiously covered with hillsides and stones, and ran to Chen Si's side.

Looking ahead from here, there is a canyon on the left and right sides of the canyon four or five miles away. Although I couldn't see anyone, I could clearly feel that someone was hiding inside. Especially when one walks through the uninhabited wilderness, the feeling is especially clear.

Zheng Anping asked Chen Sidao quietly: "What do you see?" ”

Chen Si also replied quietly: "There is a volt in the valley!" ”

Zheng Anping asked, "What do you see?" ”

Chen Si pointed to the sky and said, "Its dust is not clean. ”

Zheng Anping looked at the western sky, and saw the fluctuations of light and shadow in the canyon, Zheng Anping could even estimate that the ambush was about a mile long and should reach the scale of thousands of people through the range of fluctuations.

Zheng Anping looked at the sky, and the sun had completely set. He wondered how these people knew that they had entered the mountains, and that it was so late in the day, and that they were still setting up ambushes in the valley. This was not at all like the consciousness of a group of peasants, who must have experienced commanders and a large group of junior officers who could master the civilian army.

Zheng Anping remembered the old man's performance before leaving this morning. The old man should have known that someone with a halberd was stationed here, so he issued a warning. Ordinary peasants will not own halberds, which are complex and expensive weapons with complex production processes, and those who have halberds must be in the army, and the level is not low!

Zheng Anping felt a little difficult to ride the tiger. Moving forward is naturally self-defeating; But if you withdraw, you will lose all your previous achievements, and you are likely to be discovered by the enemy and suffer losses. The best thing to do is to stay here and wait for the enemy to lose patience.

Zheng Anping put up the halberd, then fell to the rear, and motioned for the doctor to come up. Soon the doctor climbed up the hill and said in a low voice, "The ambush is over, what is the situation ahead?" ”

Zheng Anping pointed to the canyon in front of him and said: "There are ambushes hidden in the canyons on the left and right, which is suitable for me to see!" ”

The doctor was startled and looked into the canyon, which was quiet and did not move, so he asked, "Seems to have nothing?" ”

Zheng Anping said: "The lurking is very good, silent, and occasionally we see it, but it is also vented." ”

The doctor didn't care about him, and said, "What can I do? ”

Zheng Anping said: "Just wait for it!" The doctor understood and quietly descended the mountain.

Until the sky is getting dark, a few figures appear at the mouth of the valley, look here a few times, because the valley is dark, covered by grass and stones, there is no trace of people. Then a few more people came down from the hill, about the release of the lookout post. These people met together, exchanged a few words with each other, and walked out of the crowd from the valleys on both sides, five miles away, not only Zheng Anping and others could see clearly, but even the Qin army hidden behind the mountains, rocks, grass and trees could also see clearly. Although the doctor had already passed some news to them before, when they saw so many people in ambush, everyone was still shocked into a cold sweat and couldn't help but bow down.

In the distance, you can see the crowd lined up, someone speaks, and then turns back and drives out of the valley. When Chen Si saw them leaving, he came out and quickly rushed to another observation point; Leaned less, did not wait for Zheng Anping to follow, and rushed to the next observation point. Zheng Anping didn't wait for Chen Si's gesture, he didn't dare to move, just waited in place; Seeing Chen Si lying down together, he quickly disappeared. After a while, smoke curled in the distance, and families began to raise the fire to cook.

Chen Si quickly ran back and told Zheng Anping that he had seen the situation on the other side of the valley. Now all the personnel have withdrawn from the valley and returned home. Beyond the valley there was a larger city, larger and stronger than the city of the land. The people in the city are relaxed now, and if they break in by surprise, they may be able to take the city. It's just that there are too few people now, and when the backup keeps up, you can break through.

While they were talking, the doctor climbed up the hill again and told them that a prince had led 2,000 men into the valley and set up camp in the small settlement where they had lived. The roads and commanding heights on all sides have been completely blocked, and a doctor has been sent to find here.

Zheng Anping and Chen Si went down the mountain to see the official doctor. As it was getting darker, there was nothing to be seen from that far up the mountain.

This official doctor is a Qianxian magistrate, and when he provided logistics for the Baochuan Road, he had a relationship with Zheng Anping, and they met at this time and admired each other. Zheng Anping reported what he had heard and seen today, and proposed that the one who could mobilize thousands of people to set up an ambush was probably Yan You; There was a large castle outside the valley mouth, defended by experienced generals.

Chen Si reported what he saw. The city was indeed tall and strong, but if it were to be attacked unprepared, it could have been captured in one fell swoop. And now, because they have been in the field all day, each of them is tired, and their defenses may be lax.

After listening to the report, the official doctor asked Zheng Anping and Chen Si to lead them to inspect it in person. This startled the two of them, and they even called "Dangerous!" Danger! The official doctor said: "Although the minister is ordered by the county, out of the army, he knows the things of the battle array, and it is not enough to experience it personally. Although his teeth have grown, he is willing to compete with his brothers. ”

Seeing that the official doctor said this, Zheng Anping, Chen Si, and the doctor took all the troubles and hairpins, and followed the official doctor to the mouth of the valley to investigate, and the others went out to the crisscrossing valley, lifted the guard, and rested by the river, and could only soak and fry millet in water to eat.

The official doctor and his party of more than ten people walked forward under the cover of hidden movements alternately, until they came to the mountain in front of the valley mouth. Sure enough, every stove was thriving, and people were eating in the courtyard. There were no sentry posts on either side of the mountain, and there were only people who patrolled the city every day, beating the wooden sticks in their hands.

The city was only five miles from the valley entrance, and in the darkness you could see that the gates were closed and that there were guards on the walls. Obviously, that's where the defense is focused.

The official doctor observed for about half an hour before gesturing for everyone to retreat. Retreating to the mouth of the valley and sending out sentries on all sides, the official doctor called these ten or so people together and said, "I will return to the prince to bring troops to the court, about 2,000 people." Set fire to the mouth of the valley and drive the people. Thou shalt be among them. When there is an attack on the city, let it open the door and gather the people, so that the city may be defended. Thou and the others entered with the crowd, and the waiter opened the gate of the city and welcomed the prince into the city. If this plan is successful, the city will be destroyed. Or if it does not accept the crowd, there will be few defenders of the city, and I will take things cheaply outside the city, and the army will attack, and the city will be conquered. ”

When these more than ten people heard this plan, they had nothing else to say. So the official doctor returned to the camp with a dozen or so people, and the rest stayed where they were to support Zheng Anping. In case the sneak attack fails, and they are detected and killed, these people are responsible for receiving and protecting.

In the middle of the night, when everything was silent, the doctor himself arrived with 1,500 people, and the remaining 500 people stayed in place as backup. Zheng Anping and hundreds of people have already taken off their military uniforms, only wearing short brown, holding a spear upside down, and shadowing into the valley. At the order of the prince, all the troops lit torches and rushed to the mouth of the valley, and at the same time set fire to all the weeds on the hills on both sides, and shouted at the same time. The people who were immersed in their sleep panicked, most of them were at a loss, and torches were lit in the city. So some of the people who were still sober immediately ran to the city and asked to enter the city. Zheng Anping and the others followed behind this group of people, hiding in the dark shadows.

At this moment, a neatly finished officer appeared in the city, he looked down the city, and suddenly said something in a loud voice. When the people in the city heard the sound, they turned around, held wooden sticks, and rushed towards Zheng Anping and his party. Zheng Anping knew that there was an obvious flaw that had been discovered, although he didn't know what it was, so he had to shout: "Array!" "Brought the upside-down halberd over, raised the halberd in his hand, and knocked over a few people. Fight and retreat. Those Qin soldiers who heard the greeting gathered around, joined the battle group, and according to the usual training, lined up one by one, and fought on the spot. Stabilized the formation a little. Behind him, a large number of Qin soldiers rushed in......
