Lian Po leaned over the geographical map in front of him and carefully calculated for a long time. In the end, I decided to take everyone to see the terrain again.

Shangdang and Changping are separated by a high mountain range named after Yao's eldest son, Danzhu. Danzhu Ridge stretches out four foot of the Danshui River to Changping, enclosing three valleys, and encircling the Danshui River Valley from the east. The southernmost foot of the mountain is too far away and is excluded from the defense circle by Lian Po, and the Danshui defense circle relies on the three foot of the mountain, goes around the Danzhu Ridge to the northeast, and then takes the Danshui as the edge in the west to build a fortress to defend the palace. The entire defensive circle is like a continuous huge triangular city, including the northern, central and southern three foot of the mountain, and two valleys.

The great tent of Lianpo was set up at the foot of the middle mountain, and they agreed to attack on the south side of the foot of the southern mountain. The small mountain bag that became the focus of attention was actually a continuation of the foot of the South Mountain, but it was split by Danshui with a hole four or five miles wide.

Lian Po led the group to the top of the southern slope twenty miles away, looking down at the terrain in front of them: the Danshui meandered between the two mountains. Since it was originally expected that Bai Qi would attack from Gaodu, the foot of Nanshan was built into a strong fortified area, which was the first line of defense against Bai Qi's attack. Taking this place as the starting point of the attack, it was more than twenty miles away from the enemy's camp, which was a bit far away. Therefore, the small mountain that extends from the foot of the South Mountain is a good stepping stone. Once again, the generals observed the terrain of the entire battlefield (they had lived here for two years, and they had observed the terrain of the battlefield countless times) and confirmed that an attack from the southern front was feasible. Lian Po took everyone down the mountain again, stepped out of the camp, and crossed the river to this mountain.

The small hill that extends from the foot of the mountain to the west bank of Danshui is in the middle of a plain; After going down the mountain, ten miles to the west, it is the small mountain ridge that Wang Yi relies on as the southern line; Hyun water flows slowly out of the mountains and flows southeast into Danshui. The crowd stood on the top of the mountain and pointed and discussed the plan of action.

The Qin army saw this scene at the lookout post on the opposite hill and immediately reported it to Wang Di. When Wang Yu hurried over to observe, he happened to see this group of people swaggering down the hillside, out of the barrier, and up the hill ten miles away.

Only ten miles away, Wang Yi could even see their clothing style: it was by no means a group of unknown soldiers, but a group of superior people, and one person in the middle, his status was obviously different, it was probably Lian Po! Lian Po appeared on this mountain with a group of big people, needless to say, it must be to do something big.

The five doctors and the public attendants who were in charge of the defense of this area had already arrived, and when they saw Wang Di silent, they said, "If he peeps into my camp, he will definitely attack me, and I will lead troops to attack it!" ”

Wang Yi said: "He is still far away, and he can't hit it." Look at it! ”

Wang Yi patiently observed everyone's movements and postures, and mentally speculated on what they were discussing. They stayed on the mountain peak for nearly an hour, and did not leave until the sun went down in the west. After careful observation for an hour, Wang Yi also guessed the general content of their discussion, that is, to launch an attack on the southern area. Lian Po has spoken to most of this group, and these people have also responded, they should be the senior generals of the army; There are more than a dozen people in this group, which is consistent with the information that Zhao Jun has more than 100,000 people. Combined with Lian Po's posture and the interlocutor's response posture, the participants in the attack were six or seven generals, and it is estimated that the total strength was sixty or seventy thousand, accounting for most of the Zhao army. After the group descended the mountain, Wang sent an envoy to Gaodu to report that the Zhao army would launch an attack on the valley in the near future. Not long after, the five horses galloped out of the mountain road and headed for Gaodu. The passage from the valley to the high capital was behind the mountain all the way, and it was difficult for Zhao Jun's lookout to spot them.

It was nearly late spring, the sky was dawning early, and when the drums were beating and the army was gathered, the sky was already bright. At this time, the five doctors guarding the south hurriedly came over to see Wang Yi and said, "Wu Anjun is the best!" ”

Wang Yi was shocked and said, "Please!" ”

The five doctors said: "The king ordered us to wait and go to the mountain to watch the battle." ”

As the main general, Wang Di's big tent was naturally in the center of the valley. Wang Yi hurriedly finished tidying, took two entourages and rode horses to follow the five doctors to get up. The two walked ten miles and were stopped by Wu Anjun's entourage, Wang Yi and the five doctors were led by the entourage to a hillside, Wu Anjun sat behind a large rock, intently observing the opposite hill.

Seeing Wang Yi and the five doctors coming, Bai Qi pointed to the mountain and said: "Although the mountain is close to Ruying, it is also close to the high capital, if he occupies this mountain, the traffic between the two places will be cut off." ”

Wang Yi didn't notice this at first, and when he saw Bai Qi mention it, he said: "The minister should send a department to be stationed here to be the Zhao army." ”

Bai Qi didn't say anything, but whispered to himself: "If he comes out like this...... If he comes out of this...... But what you see. ”

Wang Qi reported to Bai Qi in detail what he had observed yesterday, and Bai Qi listened, his eyes still scanning the path of the mountains and rivers below, not knowing what he was thinking. Wang Yi had stayed under Bai Qi's hands, and he had heard that Bai Qi had such an expression, and the enemy should be unlucky, so he was very excited, and the report was also a little dancing, and his voice was involuntarily higher. Bai Qi turned back sternly and said, "Whisper! ”

Wang Yi looked around, but there was no one else, so he said, "I don't hear it when I raise my voice!" ”

Bai Qi said: "Lian Po is interested in this, and his feelings are explored by you!" Rather than fear! He peeked at us gathered here, and thought about it for a while! ”

Wang Yi hurriedly lowered his voice, even lowered his body, and approached Bai Qi to continue reporting. By the time Wang Ji finished his report, the sun had already risen, and smoke was already curling in Zhao's camp. Bai Qi said: "Lian Po is a self-disciplined thief, and he can't do anything." It is to be done, but to be determined. But self-guarding the camp fence and waiting to see what happens. ”

Wang Yi and the five doctors watched Bai Qi ride away, and they also rode back.

Wang Yu summoned the five doctors and the public passengers, and told them that the Zhao army might launch a powerful offensive and was mobilizing troops for this purpose, and that the doctors must be fully prepared, vigorously prepare their troops, reorganize their armor and equipment, and pay close attention to the movements of the Zhao army.

The barracks on both sides are only ten miles apart, and when you climb the height, you can see the location of the other party's barracks, tents, barracks, and even stove pits and dung pits at a glance. Wang Yi made a point of telling the officers to tell the sentries to focus on watching if any new soldiers appeared. Someone asked, how can we know each other one by one when they are so far apart. Wang Yi said: "But look at it! As he spoke, he made a pooping appearance. Wang Di and the Bashu soldiers got along for a long time, and the language communication between the two sides was not barrier-free, and Wang Di and they could even imitate a few Shu sounds, which caused a burst of laughter.

Observing that pouting and pooping does work. Wang Yi and the others quickly judged that the Zhao army was carrying out a large-scale mobilization, and the troop movement was very hidden, and it would not be discovered by the Qin army, and it should be completed at night. But despite Zhao's frequent moves, there has never been a major public move. In order to strengthen the defense, Wang sent more scouts, forcefully expelled the scouts of the Zhao army, and consciously sent the scouts further south to cover the road to Gaodu.

Originally, the two armies were not far apart, and scout battles occurred everywhere almost every day, with casualties on both sides; On that hill, the battle was even more intense, even escalating to the scale of a hundred. Small-scale sneak attacks at night are also becoming more frequent, with both sides waiting. After half a month like this, the soldiers were exhausted.

New supplies from the Qin army were sent to Duanshi, and Wang Ji sent 10,000 people, each picking 50 catties of fried millet to the front line. After a few months of adaptation, the Bashu soldiers have been able to get used to the unique fried millet of the Qin people, and they know that they can't eat more, eat a little less every day, and the taste is still good.

Seeing that Zhao Jun did not come out, Wang Di decided to take the initiative. He sent 10,000 troops down from the northernmost foot of the mountain to attack the fortress set up by the Zhao army on the bank of the Danshui River. The Zhao army held on to the wall. The barrier is not high, it can only play the role of concealment and obstacles, and if the Qin army is allowed to get closer, it is still very likely to be overcome. The Zhao army could only set up troops under the wall, and when the Qin army approached, they would take the initiative to attack. The two sides fought desperately under the barriers. This time, the combat effectiveness of the Zhao army seemed to be inferior to that of a month ago, and under the violent impact, it quickly collapsed, and was killed and injured a lot by the Qin army. But after killing for a while, the Qin army did not dare to continue the attack, and took the initiative to return with the wounded. Zhao Jun did not chase after him, but only rescued the wounded back to the wall. The Qin army reorganized its formation two miles away and launched another attack.

Wang Ji attacked until late afternoon, stopped the attack, and Mingjin withdrew his troops. The whole army withdrew into its own ramparts.

Wang Ji was puzzled by the decline in the combat effectiveness of the Zhao army, and ordered the scouts to find a way to capture a few prisoners and come back to ask. When I asked, I found out that the food supply in the Zhao military camp was divided into levels, and the soldiers with combat missions could eat a full meal, and the other soldiers could only eat half-food. Due to the suddenness of the Qin army's attack, the Zhao army did not react, and the defenders did not have a full meal that day, but maintained half of the meal, and the decline in combat effectiveness was inevitable. When Wang asked about Changping's grain, the captives didn't know, and only replied that they had sent a batch of grain two months ago.

Wang Yu then changed the location every day, pulled all the troops up to fight for a while, and did not force any achievements, but only observed the offensive and defensive methods in various places, and looked for weak points for further attacks. The offense is all stop-and-finish. Wang found that the further south he went, the stronger the Zhao army's strength and combat effectiveness, suggesting that the elite of the Zhao army was concentrated on the southern flank.

Just as Wang Ji was thinking about whether to make a big one in the north, Zhao's army set out from the south flank that morning. Wang Ji knew that the long-prepared offensive of the Zhao army had begun.

When the Zhao army began to leave the camp, the sentinel reported to Wang Di, who climbed the southern lookout post and saw the Zhao army overwhelming. The flag is clear, and the troops are neat. The troops marched out in turn in battalion units, and each unit must stand in a position on the other side of the Danshui River. After the 10 battalions were assembled, they immediately marched forward, stopped at the designated position in front of the hill, and quickly prepared for battle. It took about an hour for the 30,000 Zhao army to be lined up in front of the mountain bag, and 20,000 people were lined up on both sides of the mountain bag, and big flags and bells and drums were set up on the mountain bag. Offensive ready.
