Li Yu received a report from the scouts last night that the 20,000 troops of the Goryeo Silla coalition army had left the city of black bones, and there were only two days left before Anshi, and the generals were summoned before dawn. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

After learning that the Silla people had actually participated in the rebellion of the Goryeo people, they also sent troops to help in the war.

The generals were furious and scolded the ungrateful white-eyed wolf of Silla, a few years ago, it was not for my Tang Dynasty to send troops to rescue, and Silla had already been destroyed by the Goryeo Baekje coalition army.

The generals in the council hall asked for their orders, willing to lead their troops to annihilate Goryeo and Silla, the two embarrassed rebels.

Wang Hu was the first to stand up and ask: "Your Highness, let me lead the army of 3,000 to flee in a big rout." ”

"General Wang is a little overbearing, but there are 20,000, and if 3,000 wants to defeat him, this is a bit of a braggart, hehehe." Gao Chongli sat in his seat and chuckled.

Striving for military merit is not such a brainless fight, if you Wang Hu takes 3,000 people to defeat, it will affect the whole army.

"Humph!" Wang Hu sneered: "General Gao Nuo has any good suggestions, but I don't want to talk about it, let me wait for a long time." ”

"I didn't think of it yet, I can listen to the opinions of the other generals here."

Gao Chongli lightly pushed out Wang Hu's words and sat quietly. The reason why he jumped out to embarrass Wang Hu is that he can't see through Wang Hu, who is a big old man, and can only rush to kill on the battlefield, but he has no ability to command battles, but he is always the first to stand up and ask for his life whenever he encounters a war, as if he can fight among the generals.

Li Yu saw the dispute between Wang Hu and Gao Chongli, although he was a little unhappy in his heart, as long as they didn't take care of the big things, they didn't bother to care. To put it bluntly, it is still a dispute between the wealthy and the Shu family, Gao Chongli is a famous general, and he is too young to rely on his father to be the general of the left prison guard, unlike his brother Gao Chongde, who has a stable personality and a somewhat arrogant temperament.

Wang Hu was originally just a big soldier in the army, and after making military merits, he was arranged to serve as a pawn in the Yanwang Mansion. In addition, this person is a little too impulsive in doing things and talking, without going through his brain, he goes straight and offends the arrogant Gao Chongli at some point, and Li Yu only recently discovered that the two of them did not deal with each other.

In order to prevent his subordinates from hurting the harmony in this meaningless quarrel, plus Wang Hu and Gao Chongli are both brave and unscrupulous, there is no need to waste time listening to the two of them break up.

Li Yu directly looked at Xue Ne, Li Yehei, Li Yexu, Cheng Boxian, Gao Chongde, Chen Xuan, and Li Shangdan, who were sitting in the lower head, and the brave and resourceful generals in the army belonged to the seven of them.

Li Shangdan is also Li Yu's brother, the grandson of Li Xiaogong, the king of Hejian County, and one of the people who are good friends with him among the younger generations of many clans.

Xue Ne has been pondering since hearing about the military situation, and must have a strategy, Li Yu asked with a smile: "Xue Dayang, is there a strategy to destroy the enemy?" ”

"Ugh." Xue Ne, who was deep in thought, was asked by Li Yu and replied: "Your Highness, 20,000 troops from Goryeo and Silla are coming to our city, and the number of enemy and our armies is equal. In addition, the enemy army reported by the scouts was a fine tax army, not the Goryeo rebels who had been the rabble of Anshi before. Under these circumstances, our army should immediately go out of the city and choose favorable terrain to attack the enemy. ”

"And most of our army are newly recruited, and although they have undergone emergency training, they are still not as good as veterans who have been on the battlefield." Li Shangdan also spoke.

"Goochen knew that before the death of Goryeo Baekje, Silla was at war with the two countries all the year round, and the army could be regarded as a division of a hundred battles. That Gao Yanwu is a veteran general of Goryeo, and his soldiers and horses are the original elite soldiers of Goryeo. Our army should be cautious in this battle. Therefore, a certain person agreed with Xue Dayang's suggestion, and it was not easy to go out of the city as soon as possible to choose favorable terrain, and he was caught off guard. ”

"The two generals and I thought of going together."

Li Yu got up and came to the Liaodong sand table that was urgently made by craftsmen in the middle of the hall, and among the generals, except for the generals who were newly organized into an army and promoted, they didn't know the role of the sand table, and the other veterans all looked strange.

In the two years after the fall of Goguryeo, Li Yu sent several groups of men and horses to survey the terrain and draw maps in various parts of Liaodong, so he had in his hands a map of Liaodong that was more accurate than that of the central Tang Dynasty.

Not to mention every mountain and every road in Liaodong, but every city and every avenue in Liaodong and the surrounding iconic mountains and rivers are geographically high, and the distance between the two places is auspiciously drawn on the topographic map of Liaodong in Li Yu's hand.

Although this map is not as accurate as modern maps, it is many times more advanced than this ancient map.

The people of Yanwangfu used latitude and longitude when surveying and mapping geographical coordinates, which improved the accuracy of drawing maps at once.

Because there is no clock for longitude, Chang'an is used as the 0 degree longitude, and the accuracy of the measured value is not too high. Due to the seasonal movement of the direct point of the sun, the measurement results cannot be compared with the previous life, but the map used to draw is much stronger than the map of the Tang Dynasty, and it is also satisfactory to use.

All this is due to the money-greedy Roman merchant, who helped Li Yu get the famous ancient Roman scholar Ptolemy's book "Guide to Geography".

Li Yu used the theory of the circle of the earth and the theory of latitude and longitude proposed in the "Guide to Geography", plus the geographical knowledge he had mastered in his previous life, to persuade the famous astronomer Li Chunfeng of the Tang Dynasty and a group of Taoist scholars who were proficient in astronomy and geography.

Although there are many mistakes in the "Guide to Geography", his theory of the circle of the earth and the theory of latitude and longitude are correct, which can be used to inspire the astronomical geographers of the Tang Dynasty. Organically combine it with Huaxia's achievements in astronomical and geographical mapping, so that Huaxia can create a new era in astronomical and geographical mapping.

Through the knowledge mastered by these astronomical geographers, and under the guidance of Li Yu, by measuring the local longitude and latitude values, and then combining with the six-body principle of planning and drawing and cartography proposed by Pei Xiu of the Western Jin Dynasty, a new method of mapping was successfully created.

This is the Liaodong topographic sand table that is presented in front of the generals today, Xu Xu Rusheng.

The generals gathered around the sand table, and Li Yu pointed to a mountain road from Wugu City to Anshi with a whip and said: "This morning, the scouts reported that the high-tech coalition army camped at the foot of Anshan last night, and it is less than 120 miles away from Anshi, which is only two days away. Along the way, many Goryeo remnants of his army raised troops to defect, and now the enemy army is approaching 30,000 soldiers and horses. ”

"What about 30,000? In the first battle of Anshi, our army only had 3,000 and fought nearly three times as much, and the entire Goryeo army was annihilated. Wang Hu saw that His Royal Highness and Xue Ne and the others attached so much importance to the enemy army coming from the black bones, and he was quite unconvinced.

It's just that Wang Hu's words didn't get a response from others, even Zhang Shi, who usually has a good relationship with him and has a similar temper, didn't pay attention to him, which made Wang Hu sulk secretly.

Li Yu glanced at Wang Hu warningly, Wang Hu closed his mouth knowingly and stood by the sand table and listened.

Li Yu continued: "Considering that most of our army are new soldiers, most of the high-tech coalition troops have been fighting for many years. If you let it go to the city of Anshi, you will fight with it. Even if our army wins, the casualties will be very large. A safer way is that I want to set up an ambush on the mountain road from Anshan to Anshi. ”

Gao Chongde took a closer look at the mountain road from Anshan to Anshi on the sand table and asked, "I don't know where Your Highness wants to set up an ambush on this mountain road?" ”

"Right here." Li Yu whipped a little and pointed at a Da'an Mountain valley on the sand table that ran east-west.

This valley is no more than 90 zhang wide and 13 miles long. The north side is Da'an Mountain with an altitude of 210 zhang, and the south slope of the west section is gentle, and thousands of soldiers and horses can be hidden. The south side is more than 120 zhang of the South Yellow Ridge, the South Yellow Ridge is divided into several hills, there are small valleys between the hills, the slopes are relatively gentle, and tens of thousands of soldiers and horses can be hidden.

At this time, Changbai Mountain was sparsely populated, and the surroundings of Da'an Mountain and Nanhuangling were long since they were inhabited because of decades of war.

Li Yu thought about the map for a night before choosing this place to ambush.

Xue Ne, Gao Chongde, Chen Xuan, Li Shangdan and others carefully looked at the sand table and then took out the map to look at it, and nodded frequently: "This place is a good place to set up an ambush." ”

"According to the calculation that the army traveled 60 miles a day, the Goryeo Silla coalition army camped in Anshan last night, so its army will reach Da'an Valley tomorrow." Xue Ne was surprised and said, "Your Highness, our army should immediately go out of the city and rush to the Da'an Mountain Valley, otherwise it will be too late." ”

Li Yu waved his hand and said: "Xue Dayang, rest assured, I sent Cui Xuan to prepare the grain and grass needed by the army last night, and the whole army can be camped today, and we can reach the Da'an Mountain Valley tonight." ”

"That's good." Xue Ne was taken aback, as the saying goes, before the soldiers and horses move, the grain and grass go first.

If the grain and grass that have always been prepared for the troops are opened today, it will take half a day to prepare them soon, and then there will be enough time to rush to Da'an Mountain, and even if they arrive, they will be tired enough, and they will not have the strength to fight. Fortunately, I started preparing last night, no wonder there was a lot of noise in the city last night.

"The generals obey orders."

Li Yu returned to his position and said to the dozens of generals in the hall: "Li Shangdan, Gao Chongde, Wang Hu, the three of you led the White Tiger Guard, Zhu Que Wei, and Xuanwu Wei as the front army to set off first, Yu Chengzhi, Li Laiheng, and you two led the Qilin to guard Anshi." The rest of the generals led the troops and horses to set off with the king, and the whole army marched to the Da'an Mountain Valley to set up an ambush. ”

"No."

As soon as the morning dawned, the entire city of Anshi moved, and tens of thousands of troops were ready to go.

Li Yu gave an order, and in addition to the more than 2,000 soldiers and horses of the Qilin Guard guarding An'an City, the whole army of 18,000 people marched out of the city and headed east.

The army stretched for miles, flags fluttered, and a bloody battle of tens of thousands of people was about to break out.

Whether it was the victory of the Goryeo and Silla coalition forces, which had many generals, or the victory of the Tang army, which was majestic and powerful, and had high morale, everything was unknown.

"After thirty miles of mountain roads, you will arrive at Anshi." Quan Shuijing led more than 100 of his subordinates to quickly investigate the situation of the Tang army in Anshi.

A personal soldier came up with some worry and asked: "General, more than ten days have passed, what if there are reinforcements from the Tang Army in Anshi, and it is no longer 3,000 people?" ”

"If it's not 3,000, it's 3,000."

"This?" The pro-soldiers were a little puzzled.

The spring looked in the direction of Anshi to the west, and said with a slight mockery: "Gao Yanwu is just a lackey who has taken refuge in Silla now, and he is bent on preserving his strength. There are only 3,000 Tang troops in Anshi, this guy is naturally willing to come and pick up the cheap, and after the reinforcements of the Tang army, Gao Yanwu may immediately retract his black bones. In this way, when will Goguryeo be recovered? Therefore, in order to force Gao Yanwu to capture Anshi, the Tang army in Anshi could only be 3,000 people. ”

"Besides, there are not many Tang troops in Liaodong, if there are reinforcements, they can only be soldiers and horses from Tang Guoying Prefecture, but how many soldiers and horses can Yingzhou come to reinforce Anshi?"

"No matter how you count it, there are more soldiers and horses in our army than in the Tang army, and the soldiers and horses under Gao Yanwu are not a group of rabble pulled up by the incompetent people of Shaomuro Jiakang, not to mention that there are 10,000 Silla elite soldiers."

"Whoosh, whoosh, whoosh......"

"General, be careful......"

Dozens of arrows suddenly shot out from the forest, which made more than 100 people in the group of Quanshuijing frightened, and hurriedly drew their swords to block the arrows.

The keen eyes in the forest stared at Quan Shuijing and the others, pulling the bow and arrows, and the arrows kept flying to the crowd in front of them, and after the arrows disappeared, there was a screaming and thudding sound of falling off the horse.
