At dawn, Shouchun Castle was as silent as usual, but as the city gate was opened, the whole city became agitated, and a stream of people and vehicles mixed with infantry, cavalry, and chariots poured out of the south gate of Shouchun Castle like a flood from a flood bank.

War horses are galloping, chariots are galloping, and people are galloping all the way, and this torrent of the Huainan Army launched an unstoppable attack on Sima Jun's company camp position.

Wang Feixiao knows very well the importance of a blow, now the Huainan army is full of war meals, it is the time when physical strength and energy are the most vigorous, if you can use such a momentum, in one fell swoop, break through the defense line of Sima Army, then the battle of breakthrough can be successful, but if the breakthrough is blocked, morale falls, then the effect of the second attack will be greatly reduced, whether it can finally break through successfully, it is really difficult to say.

After careful reconnaissance in advance, Wang Feixiao had already grasped the general situation of Sima's army's defense line, although Sima's army was known as 200,000 troops, but at least half of the army was deployed on the Hefei line to deal with the reinforcements of Eastern Wu.

The army that really besieged Shouchun City was actually only 100,000 people, and these 100,000 people were evenly distributed in the four directions of southeast, south, and northwest, and in each direction, there were only 25,000 people at most.

Although there are many defectors in the Huainan Army, in fact, most of the defectors are from the civilians recruited later, these civilian recruits lack combat experience, and their willpower is much weaker, so they are simply useless, so the only ones who can really come in handy in the battle of the breakthrough are Wang Ling's descendants, they are the backbone of the Huainan Army, and the biggest reliance on this breakthrough.

This army has more than 50,000 people, which is a real elite force, although the number is only half of Sima's army, but if Wang Feixiao's tactics are used properly, then he can form a superior force in the local area, and use this force to complete the breakthrough, Wang Feixiao is still full of confidence.

The company camp of the Sima army besieging the city was not set up under the city, but it was separated from Shouchun City by a distance of about two miles, that is to say, there was an open area of about two miles on both sides, tens of thousands of troops went out of the city, and the movement was extraordinary, and the Sima camp there was always a sentry staring, once it was found that the Huainan army had the intention of breaking through, it would immediately warn, and the defending army would be put into battle at the first time.

Wang Feixiao is not worried that Sima Jun will be alert, such a big military operation, it is impossible for the other party to be unprepared, so even if Wang Feixiao chooses the time to break through in the early morning, it does not mean that he wants to confuse the opponent.

In order to besiege Shouchun City and prevent the Huainan Army from breaking through, Sima Yi ordered to dig a wide and deep trench on all sides of Shouchun City, like digging a moat, and used the excavated soil to build a high fortress on the periphery and build fortifications.

Although in order to make it convenient for the people in the city to escape, the trench of the Sima army was not completely dug through, and some sections were passable, but these sections also placed a large number of horse-repellent antlers, and sent heavy troops to garrison, and these sections were very narrow, and the widest place could only accommodate two or three horses in parallel.

Obviously, Wang Feixiao could not expect to seize these passes and let the army break through, what he had to do was to fill in this trench and pave the way for the army to break through.

Taking advantage of the opportunity of Sima Jun's deliberate relaxation of vigilance, Wang Feixiao had already sent someone to find out the defensive situation of Sima Jun, in fact, Sima Jun's defense line, the most difficult to break through is such a trench, as long as the Huainan Army is difficult to step through this trench, the rest is a smooth road.

Of course, behind the trench, there is also Sima Jun's company camp, but compared to the difficulty of the trench, the Huainan Army's horse stepping on the company camp is at least relatively easy.

In order to cross this trench, Wang Feixiao still made a lot of preparations in advance, he ordered the vanguard of the Huainan Army to prepare a cloth bag for each person, and fill the pocket with soil, even if Sima Jun dug the trench wide and deep, but tens of thousands of sand bags were thrown in, Wang Feixiao really didn't believe that it could not be filled.

In fact, the Huainan Army does not need to fill in all the trenches, it only needs to fill in a road dozens of zhang wide on the way forward of the Huainan Army, so that these sandbags are more than enough.

After leaving the city, Wang Feixiao immediately ordered the army to move forward quickly, and to launch a surprise attack while Sima's army was unprepared, and first fill in the trench.

The reason why Wang Feixiao chose to do it at this time in the early hours of the morning is precisely for this reason, at the fifth watch in the morning, it is the time when people will not wake up, such a large-scale operation, I don't want to be discovered by Sima Jun, it is impossible, but at this time period, except for the sentry, most of the soldiers are probably in sleep, even if they get the warning from the sentry, it will take at least a certain amount of time from waking up to entering the battle, and this time period is enough for the Huainan army to rush from the city gate to the front of the trench.

As long as the trench is filled in first, then the defensive line deliberately arranged by Sima Jun will become an ornament, and the chance of the Huainan Army breaking through will be greatly improved.

As soon as the Huainan army left the city, there was a piercing bang sound from Sima Jun's side, and it was obvious that Sima Jun's sentries had discovered that the Huainan army was coming to attack, and deliberately rang the bangzi to warn.

Wang Feixiao didn't care, maybe this situation was already in his expectation, Sima Jun's sentries must be on call at any time for twelve hours a day, and if they want to bypass them and not be discovered, unless the Huainan Army is invisible, it will definitely not be possible.

What Wang Feixiao needs to do is to catch the time between Sima Jun's warning and the time he enters the battle, rush to the front of the trench as fast as possible, throw these tens of thousands of sandbags into the trench, and wait for Sima Jun to react, and the trench will almost be filled.

However, just when the Huainan army was just approaching the trench only a stone's throw away, suddenly ten thousand arrows were fired at once, as if a storm was suddenly ushered in overhead, and the Huainan army was caught off guard, and many soldiers fell to the ground one after another.

The vanguard of the Huainan Army, according to Wang Feixiao's requirements, each carried a sandbag, which was filled with sand and soil, and the weight was not light, each weighing at least fifty or sixty pounds, and the volume was not too large.

With sandbags, you can no longer carry protective shields, although sandbags can also be used as protective gear, but the area is too small to play a little protective role.

Moreover, the sandbags are heavy and heavy, which also affects the movement speed of the Huainan Army, so under the random arrows, the casualties of the Huainan Army are really not small.
