Wei's Huainan defense line is not all south of the Huai River, in fact, this defense belt is across the two banks of Huainan, the main purpose of creating such a defense line is to prevent the Huainan defense line from collapsing after the loss of Huainan, and Huaibei has no danger to resist, resulting in a direct threat to the hinterland of the Central Plains.

Therefore, the entire Huainan defense line is actually multi-depth, and Ping'a, on the north bank of the Huai River, is a stronghold of its strategic defense.

After Wang Ling surrendered to Wu, the strategic location of Ping'a City immediately changed, and Ping'a City, which was originally used as a rear defense stronghold, immediately became a bridgehead against Sima Yi's army, and the total number of troops stationed here was less than 1,000 people, but now Wang Ling has transferred 5,000 more people to Ping'a, and the defense force has been greatly enhanced.

If you want to attack Shouchun, you must first take Ping'a, Sun Li this time from Yanzhou south to attack Huainan, the first target to attack is Ping'a.

Due to the heavy snow blocking the road and the difficulty of the road, the vanguard led by Sun Li and Sima Shi did not travel fast, and the distance of five or six hundred miles lasted nearly seven days before reaching the city of Ping'a, and at this moment it was already Chinese New Year's Eve.

Although firecrackers have not yet been invented in this era, there is a little less joy and liveliness, but people's enthusiasm to welcome the New Year is still so high, even the city of Ping'a, are lit up, people are waiting for the arrival of the New Year.

But for Sima Jun, who came from a long distance, they didn't have any idea of celebrating the holiday, this Chinese New Year's Eve, as cold as before, the thick snow seemed to greedily swallow up all the heat in the air, although Sima Jun's cold protection equipment was relatively complete, but in this cold snowy night, even the most expensive fur fox fur was difficult to resist such a biting cold.

Now Sima Jun's only way to keep out the cold is exercise, long-distance high-intensity marching does help the human body to maintain heat, but people are not machines after all, when the physical strength and energy are exhausted, then you need to camp and rest, get into the thick cowhide tent, build a bonfire, and drink a pot of hot water, which is enough to resist the cold.

Previously, the Sima army basically used this method, although the weather was cold, but the non-combat attrition was relatively small, but when it was close to Huainan, Sun Li suddenly ordered the army to prohibit ignition at night.

Of course, Sun Li did this for a reason, after all, in the plain area, at a glance, the fire at night can shine dozens of miles away, for the sake of insurance, Sun Li ordered a ban on fireworks, when camping, can only drink cold water and eat dry food, the conditions suddenly become difficult, and the non-combat attrition is becoming more and more.

But this is also a last resort, Sun Li knows, if he doesn't want to expose the whereabouts of the army, prohibiting fireworks is the first condition, if he can't help it, wouldn't it tell the enemy that we are coming?

It was only five or six miles away from Ping'a City, at this time the sky had finished dark, and the lights of Ping'a City were faintly visible in the distance, Sun Li ordered the army to temporarily stop advancing, Sima Shi thought that he was going to order camping, but to Sima Shi's surprise, it was Sun Li who gave the order to attack Ping'a City at night.

Sun Li explained it like this: "This place is only five or six miles away from Ping'a, and it is easy to be discovered by the Huainan people. ”

Sun Li had also participated in the construction of Ping'a City, so he knew very well how strong Ping'a City was, although it was not as solid as a rock, but as the strongest stronghold on the north bank of the Huai River, Ping'a City's defense capability was definitely no less than those important passes.

Taking advantage of the fact that the Huainan army was relatively lax in the cold weather near the end of the year, the Sima army took Ping'a and crossed the Huai River south to take Shouchun in one fell swoop, and solved the rebellion of Huainan in one go.

Therefore, attacking Ping'a is the most important step, according to the previously discovered information, Wang Ling strengthened Ping'a's garrison, from the previous 1,000 to 6,000 people, that is to say, the defense capability of Ping'a City has increased by five or six times out of thin air, which is definitely not good news for the Sima army, which is slightly tired from a long march.

If the Sima army loses its concealment and turns the sneak attack into a strong attack, then the consequences will be simply catastrophic, don't look at the vanguard of the Sima army, which has 50,000 people, which is ten times the number of the Ping'a defenders, and once they enter the battle, they will inevitably taste the bitterness.

What's more, Ping'a and Shouchun are only separated by a river, and when they fight together, Shouchun's enemy can easily reinforce Ping'a, making Ping'a a hard bone to gnaw.

So this rush, Sun Li's goal is very clear, that is, to carry out a sneak attack on Ping'a City, and now he has arrived at Ping'a City, he is not willing to camp first and then attack anyway, he decided to rest for a while, and then in the vanguard, select a sneak attack army of about 5,000 people, and attack Ping'a City overnight.

Sun Li's plan was simple and straightforward, and he quickly selected 5,000 elites out of 50,000, and after a full meal of war, he took advantage of the night to launch an attack on Ping'a City.

The moonless night was originally dark, but at this moment, the four fields were white, and the snow shone on the way forward, so Sima Jun arrived at the foot of Ping'a City without difficulty.

At that time, it was already midnight, and the city was quiet, especially at the head of the city, not even a single figure could be seen, probably at this moment the army defending the city also went back to the barracks to sleep, no one would have thought that there would be any special situation in this big New Year.

Sima Jun traveled lightly, without any large equipment, not even a ladder for siege, only carrying flying claws and ropes.

However, it was only enough for the elite death squad in the army, and quietly arrived at the city, seeing that there was no one, Sima Bing immediately threw out the flying claws, this five-claw barb type flying claw can easily hook the city wall, Sima Bing pulled the rope hard to ensure that the hook is firm.

Dozens of ropes hung down, those agile Sima soldiers pulled the ropes, kicked the city wall, "swish", and climbed up quickly, dozens of people acted at the same time, the movement was like the wind, the speed was extremely fast, but in the blink of an eye, these soldiers had already climbed to the top of the city.

At the head of the city, although most of the Huainan soldiers returned to the barracks, there was still a small number of troops stationed at the head of the city to sentry, and the sudden appearance of the Sima army made these Huainan soldiers who were napping couldn't help but beat a spirit, and shouted loudly: "There is an enemy attack!" ”...
