Shao Yi was looking at the iPad under the desk, and the dense small print on it read:

"陉" is a river valley or valley that cuts through the mountain range and interrupts the mountain range, and this kind of valley that intersects almost perpendicular to the mountain range is also called "horizontal valley".

Jingcheng is an ancient post road that stretches for thousands of years, and it is also the fifth path of the Taihang Eight Paths, which crosses the main vein of Taihang from west to east, and is an important ancient post road connecting the Fenhe Basin and the North China Plain.

It is recorded in "Lü's Spring and Autumn"......

Just as he saw this, Shao Yi suddenly heard Feng Luotang's name. He raised his head sharply and saw that Li Xiangxiang, the physics teacher in front of him, was pointing Feng Luotang's name.

Shao Yi was more sensitive to Feng Luotang's name than his own.

He glanced at Feng Luotang in the front seat, and found that her long soft hair was hanging down, and her forehead was resting against the desk, not moving.

Feng Luotang's tablemate Xiaofuzi hurriedly poked her with his elbow and called in a low voice: "Luo Tang, Luo Tang, Xiangxiang called you!" ”

Feng Luotang suddenly came back to his senses. She didn't know where to go just now, and she was distracted. Looking at Li Xiangxiang in front of her, a pair of big round eyes were staring at her.

Suddenly, Feng Luotang felt that Xiangxiang's eyes were like the pair of wide-eyed leopard eyes of her mount, the Chijin Leopard?

She stood up in a panic, and the table and chairs made a chaotic noise. Looking up, Li Xiangxiang pointed to a question on the blackboard and asked her, "Tell me about the solution to this problem." ”

The topic is: People always see lightning before they hear thunder. If the speed of light of lightning is c, the speed of sound of thunder is v, and the distance of lightning from people is s, what is the time interval from seeing lightning to hearing thunder?

Feng Luotang looked confused, and rolled his eyes greatly in his heart.

Then Nei complained: "This is lightning and thunder, I have to ask the young master about this." ”

Then she began to play back in her mind after Shao Yi sacrificed the Thunder Flame Order, did she hear the sound first or see the flames first? I remember the last time I fought with Fan Yuzhi, I obviously heard the thunder first, how could I see the light first? That light is also the light wave sent by Fan Yuzhi.......

Feng Luotang suddenly had a muddy paste in his mind.

Teacher Li Xiangxiang saw that she frowned and didn't speak, and inexplicably seemed to be standing and distracted, so she had to call Feng Luotang's name again.

At this time, I heard a calm and calm male voice coming from behind: "Teacher." ”

Feng Luotang was overjoyed: "Young master, young master." Helping the needy is enough righteousness! Then he turned around slightly and looked at Shao Yi happily.

Shao Yi stood up and said calmly to the teacher, "This is an Olympiad physics problem. Let me try? ”

Li Xiangxiang didn't want to be embarrassed in class for another second, so she flashed her round eyes into light bulbs and flickered her approval.

Shao Yi lifted his long legs, stepped out of the desk and chair that was already too small for him, walked up to the podium, and quickly wrote the formula on the blackboard.

Teacher Xiangxiang was very satisfied, and after letting Shao Yi go back, he nodded to Feng Luotang, who was still standing, and didn't know whether to "mourn her misfortune" or "angrily" glanced at her, and finally let her sit down.

Shao Yi understands that Feng Luotang has often been distracted recently. My mind is full of the coming big war. So when he walked back past Feng Luotang's seat, he gently patted Feng Luotang on the shoulder.

Feng Luotang's head hung down slightly with this beat. She bit her lower lip lightly with her teeth, but there was a sweet feeling in her heart.

Physics class is the last class of the day. As soon as the bell rang for the end of class, Feng Luotang crossed Li Xiangxiang like a milk swallow throwing into the forest and flew out of the classroom.

Shao Yi followed out unhurriedly behind, one after the other, and Feng Luotang walked towards the school gate. Then they got into a military jeep together.

"How? Brother Yu, Brother Hei, let's talk about it, let's talk about it. As soon as he got in the car, Feng Luotang couldn't wait to ask.

"I fought two more times. All won. Long Xuanchen said lightly.

"My black brother is mighty!" Feng Luotang praised sincerely.

"It's hard to defend the fat city." Lin Yu's voice was still unwavering, "However, because we burned most of their siege equipment, although there are many people, it is not possible to break the city in one day." ”

The military jeep drove quickly to the west mountain, and soon, it stopped at a quiet private restaurant, the Sheng family compound.

This restaurant is nestled in tall locust trees, with a faint beige in the snow-white whiteness of the early-blooming locust flowers, bringing a faint fragrance to the courtyard.

In the courtyard, the blue brick paving, the carved brick lintel, and a flower-blooming and wealthy shadow wall are several quiet private rooms.

Lin Yu easily pushed open the door of one of the private rooms. Feng Luotang immediately "snorted".

In this room, the walls are covered with all kinds of maps, including ancient battlefields, modern satellites, marching formations, and high-definition geological topographic maps.

Even a round table was set up for eating. Feng Luotang took a closer look, and it turned out to be a map of the Six Kingdoms of Qin's Annihilation.

"This room Shao Yi has temporarily chartered for us," Lin Yu said to everyone: "The food is authentic, the most important thing is that it is very quiet and safe." ”

"Young Master?" Feng Luotang looked at Shao Yi incredulously.

Shao Yi touched his nose with his fingers a little embarrassed, and explained to Feng Luotang in a curtled manner:

"My dad is investing in an industry under a business. I didn't bring you here to eat because of my father's house rules. He said that it doesn't matter if he earns money or not, he can't afford to eat his own poverty. ”

"But if I really want to find him and say that I am of great use, I will not immediately support us."

Shao Yi caught Feng Luotang's white eyes with a smile, and added: "Biological, that's right!" ”

Everyone was amused by him, and looked around at the layout of the private room.

In fact, this room was originally quite elegant, with mahogany furniture, with incense burners, tea seas, copper kettles and pen and ink, and it is estimated that Gongzijia will not be wronged by him here.

However, now that Lin Yu and Shao Yi are acting like an operational headquarters, there is a sense of disobedience in the national army's wanton requisition of private houses.

After a few words of laughter, the four of them gathered in front of the map on the table, gathered around, and analyzed and studied for more than three hours, basically reaching a consensus on the upcoming battle.

Lin Yu named the battle "The Battle of Jingcheng". This was the first battle of the four "new dragon phases" organization.

Originally, this fat battle was Li Mu's home field. But......

"First of all, we helped him defend the fat city. In the past two days, he will use the method of 'encircling Wei to save Zhao', and see the 'encirclement and reinforcement' of the attack on Huan Qi. It is expected that just tonight, he will sneak attack the Chinese army camp in Huanqi.

The camp is surrounded, and Huan Qi will come to the rescue from the fat and tired countersoldiers. If he is not rescued, the retreat of his entire army will be cut off, the supply of grain and grass will be cut off, and he will become a lonely army without roots and no source.

However, according to the analysis, if Li Mu sent an army to attack the Qin army's camp, the first to come to the rescue should be the Wang Ke Department of the Left Army arranged by Huan Qi in the upper reaches of the Taohe River, and there should be at least 30,000 or 40,000 people.

If this force rushes to the aid of the Huan Qizhong military camp and leaves the upper reaches of the Taohe River, we will have a chance to capture Jingcheng.

Originally, the biggest threat to the seizure of Jingcheng Pass came from Luquan City, where there were 8,000 garrisons, very close to Tumen Pass, five miles to the west, it had already entered the Jingcheng boundary, and a total of sixty miles to the middle of the larger garrison of Jingcheng Pass.

So if we want to capture Jingcheng, the first thing we need to do is Tumen Pass. And Luquan is the closest to Tumen Pass, and will immediately rush to the rescue. The defenders of Luquan may divide up to 5,000 men to meet them.

So our basic battle plan is as follows:

First of all, take advantage of the night to snatch the earthen gate. To attack Tumen Pass, it should be inserted from the foothills of the calf near the west side of Tumen Pass, just suitable for our tigers and leopards to help and break into Tumen Pass.

Subsequently, if the 2,000 garrisons of Tumen Pass can escape to the pass, they will definitely unite with the defenders of Luquan, and our Zhao army should send at least 15,000 absolute superior forces to surround it and recover Luquan.

After that, we will open up the net of the defeated army in Luquan City, and use tigers and leopards to drive each other, and we can set up an enchantment at Weishuipu, thirty miles west of Tumen Pass, so that about 8,000 people can first go to Hanhaizhou from the enchantment.

After that, our Zhao army changed into the Qin army's uniforms and armor, and then went thirty miles to the west, crossed the Mianshui, and pretended to be defeated to storm the Jingcheng Pass, striving to catch them by surprise.

There are 5,000 defenders at Jingcheng Pass, and if they lose the pass, they must pass through a narrow valley of several hundred miles to retreat in the direction of Qin.

It is said that the cart of the valley cannot cross, and the two horses are not side by side. So we only need to choose the narrowest mountain pass and set up an enchantment, and we can lead them all to Hanhai Continent.

The Zhao army obtained the Jingcheng Pass, but it could defend it according to the danger, completely cut off the retreat of the Qin army, and surrounded and eliminated the Huan Qi army.

Therefore, our last step is only to open the earth gate and attract the defeated army of the Qin army to enter. As before, set up an enchantment on the way to Jingcheng Pass and rescue them back to Hanhaizhou.

The goal of the first battle was to capture 10,000 defenders of the Qin army's Tumen and Jingcheng passes, 20,000 people from the left army's Wang Kesuo Division, and 20,000 of Huanqi's retreating army, totaling 50,000 people to Hanhaizhou. “

Lin Yu summed up the results of everyone's discussion, finished speaking in one go, was silent for a while, and raised his head to look at Feng Luotang and Shao Yi.

"Tonight is the time when Li Mu's army is about to attack the main camp of Huan Qi. You two will fight quickly, and the battle will be successful, otherwise all plans will be frustrated. ”

"Do your best." Shao Yi replied succinctly.

"But Brother Yu, what about those Qin troops who entered Hanhai Continent in several batches? Will it turn our hometown into a miasma and turn the world upside down? Feng Luotang asked with a raised face.

"No," Long Xuanchen said, "I have already persuaded Senior Brother Ge Nie to enter Hanhai Continent first. He has in his hand the handwritten letters of the King of Qin to control the various armies, and his martial arts are unmatched, he will definitely be able to control all the Qin armies. ”

"Luo Tang, Hanhaizhou is rich in products, and it is controlled by Yunzhongjun, so there is no need to worry." Lin Yu added: "After we finish this battle, we will go back to Hanhaizhou and slowly recruit this group of people to join the Dragon Clan." ”

Several people discussed the plan, and their hearts were determined, and they fiercely picked up a meal to prepare for the war, and told each other that there was no need to force it when something could not be done, and they must remember to return the dream spell to save their lives, and then they dispersed.

Li Mu's army had a loud horn, a banner waving, and a grand march from Gaocheng.

Zhao Guo participated in the war this time, with a total of 130,000 troops. Among them, the main force of 80,000 is like a tide, rushing straight to the south, and there is a great tendency to vow not to give up until the fat tired city is saved.

Huan Qi was overjoyed when he got this report, and he was busy arranging ambushes for various departments.

The military orders went down one by one, but he never thought that the latest investigation report showed that Li Mu's army suddenly turned back halfway and diverted to the northwest.

At the same time, the 50,000 troops left in Gaocheng were led by the veteran general Le Cheng, poured out of the city, and went upstream along the Tao River to attack the Wang Ke Department of the Huan Qi Left Army.

Hearing the news, Huan Qi's heart immediately pinched.

His Chinese army camp was the target of Li Mu's army. Although there were still 20,000 people guarding there, almost all the grain and grass and most of the ordnance and equipment in this battle remained in the Chinese army camp.

Originally, this attack on Feiti City was just a move to attack the east and the west. Huan Qi led the army to all the troops lightly armed, and only made preparations for a few days of battle.

Huan Qi knew that if the Chinese army camp was attacked, the consequences would be unimaginable.

Thinking of this, Huan Qi was shocked. He immediately gathered the men and horses that had been arranged again, preparing to outpace Li Mu with speed, and inserted it from the diagonal rear before Li Mu's army hit his Chinese army camp, dealing a heavy blow to Li Mu's army.

But Li Mu's speed was not something Huan Qi could predict.

These light horses coming down from the Hun battlefield are like tigers suffocating their strength in prison, and the day they break out of the cage is the time of invincibility.

Zhao's cavalry, especially the five battalions of light cavalry under Li Mu's personal commander, has always been known for their speed.

By the time Lu Xian, the rear general of the Chinese army, and Guo Teng, the general of the Chinese army, got the report of Tanmalai, Li Mu's army was only a dozen miles away from them.

Guo Teng was shocked but not confused, quickly ordered all the men and horses, quickly allocated 5,000 from the remaining 20,000 people, and immediately began to transfer the army's grain and grass in the direction of Tumen Pass.

He made a careful arrangement of the remaining 15,000 men and horses in front of the barracks.

Guo Teng still has an old injury that has not healed. He urged his horse to straighten his modest body on the back of the tall horse. A pair of stumbling silver hammers hung from the saddle bridge.

Guo Teng's face was very calm, without a trace of expression, and he stood in front of the formation with Lu Xian.

Although he had already sent someone to send a request for rescue to the nearest Wang Kezuo Army, Guo Teng knew in his heart that a famous general like Li Mu would not give Wang Ke a chance to rescue the Chinese army battalion.

If Li Mu can't hold out for many days, just to strike at the Chinese army camp at this moment, then I'm afraid this camp will be broken today.

Guo Teng led the army forward with the determination to die, waiting for the dust from the gradually rising horses' hooves in the distance to get closer and closer, and then he shouted: "Crossbowman, prepare." ”

The Qin State Giant Crossbow is very strong, and it takes a person to lie on the ground and use the strength of his legs to reload the crossbow arrows, and when launched, it has the power to pierce the armor and pierce the shield. It was the Huns who were far away in the depths of the grassland who talked about the tiger color change to the Qin crossbow.

Li Mu asked the left wing cavalry led by Li Hong and the right wing cavalry led by Li Ji to temporarily stop their troops from entering the range of crossbow arrows from the Chinese army's camp.

The black oppressive Zhao State infantry and crossbow soldiers, layer after layer, like a churning black wave surging to the forefront of the cavalry.

Li Mu rode on a tall inky black horse, majestic and calm, and remained silent.

Suddenly, he gave a dull command: "Charge!" ”

These two words are the order to start the whole campaign.

The Zhao army launched the first charge of infantry and chariots. One hundred and fifty chariots continued to advance, and a three-layer copper shield array composed of bronze shield hands intercepted Qin's arrows and crossbows at the forefront. He was followed by the archers of the Zhao army.

After entering the firing range, countless arrows rained down and covered the sky.

Qin's crossbow is indeed powerful, and it has the ability to pierce shields and break cars, but unfortunately the reloading is too slow, and the launch is even slower.

The Zhao army charged quickly and quickly forward, gaining the upper hand by overwhelming the Qin army's numbers.

Later, the general Lu Xian bravely resisted the charge of the Zhao army and died in battle.

Guo Teng first swung his hammer on his horse to supervise the battle, and then, with an order, he took the main cavalry of the Chinese army battalion and began the first charge of the Qin army.

He took the lead, wielding two hammers like wheels, and rushed into the vanguard soldiers of the Zhao army. Each swing of the silver hammer brought out lines of blood.

Guo Teng's bravery and ability to fight, no one can get close to him. Inspired by him, the Qin soldiers resisted bravely. Charging again and again, Zhao Jun was unable to move forward.

At this time, the Zhao army was drumming loudly. The rhythm of the war drums of "Dong Dong" is fast and slow, as if it is summoning the god of war on the horizon to come and cheer.

Hearing the beating of the war drums, the cavalry on both wings suddenly began to charge.

The formation of the cavalry army was like two sharp cones that chiseled through Guo Teng's charging army, quickly cutting the Qin army into three parts.

The Zhao army rushed into the battle formation of the Qin soldiers with light horses, tall men and horses, spears and long halberds, and fought with the Qin army, which was mostly infantry, and had the advantage in fighting, like a machete cutting vegetables.

The Chinese battalion of the Qin army had more infantry and less cavalry.

Soon, the cavalry of the Qin army was squeezed by the light cavalry of the Zhao army and retreated in all directions, and could no longer form a complementary battle group with the infantry, so it could only be supported independently, and was gradually surrounded and annihilated by the cavalry of the Zhao state.

The battle between the two armies was extremely fierce, and in the sound of war drums, it was killed from noon to dusk, and the shouts of killing did not subside.

Although the Qin army was small in number, it fought to the death and did not retreat, and the casualties were naturally very heavy.

Guo Teng was already covered in blood and injured in many places, but he was still like a seriously injured beast, constantly charging, taking the lead and rushing to the front.

When the sun turned west, Guo Teng saw that the Grain and Grass Army had long since disappeared, so Mingjin gathered the Qin army that still had combat strength and retreated.

Li Mu's army, which succeeded in the first battle, occupied the Chinese army camp of the Qin army. Because the main grain and grass camp had been slowly withdrawn by Guo Teng, many soldiers suggested taking advantage of the victory to pursue.

Li Mu smiled and said nothing.

In the middle of the night, facing the re-lined Zhao army, he said loudly: "Soldiers, this time our 'flowers' are not this big battalion. We're going to wait here for the fattest bunny, Flower, to hit me. Let me see which battalion of heroes caught this 'flower'. ”

His speech aroused the pride of all the sergeants, and the cheers of the officers and men of the Zhao army were deafening.

At this moment, the stupid rabbit "Hua'er" Huan Qi really led the army to withdraw from Feiti City in a hurry and went straight to the direction of the Chinese army camp.

He actually understands very well that if he loses the camp of the Chinese army, if he loses the Jingcheng that returned to the Qin State, then he will become a lone wolf outside Handan City, even if there are 100,000 military horses, he will not be able to withstand the gnawing of Li Mu's army, and sooner or later even the behemoth will fall.

So he decisively gave up the fat city and returned to his division to save himself. But it was precisely this turning back path that he took that ruined all his chances of winning in this battle.
