Hundreds of miles south of Liangzhou, on the Xucheng Plain, there was a big offensive and defensive battle, and a fierce battle was raging.

Over the past few days, the Vietnamese army has launched more than 20 fierce attacks on the Liangzhou military camp, but the result is still unable to break through the enemy camp here, and it is impossible to seize the road to the north.

You must know that these more than 20 attacks are not just blind attacks, in addition to relying on the frontal attack of troops, Sun Ning and Chen Qingyun have repeatedly changed their tactics and used other strategies to attack.

For example, trying to divide the troops and make a detour, or sending troops to storm the high ground on the left side of their camp, intending to flank the enemy's camp from the heights, as well as night attacks, fire attacks, and false surrenders......

Sun Ning and the others used all the strategies that could be used at the moment, but as a result, all offensive strategies failed to work.

Song Qiyun seemed to have considered all the possible threats at the beginning of the camp, and he actually defused all the attacks one by one with less than one-third of the enemy's troops.

If you attack, he will defend as a rock, and fight a war of attrition with strong fortifications and the resolute attitude of the whole army.

If you divide the troops, he will set up an ambush trap on the road that must be passed one step earlier, causing the generals who led the troops to return with their feathers, which will damage the morale of the Vietnamese army.

As for the way to seize the high ground on the side, it is even more difficult.

The fortification of the defense line over there is even higher than that of the camp, after all, the high place occupies a condescending geographical advantage.

So, when Nie Long, who took the initiative to invite Ying, to lead his troops to launch an upward attack on Xiaoshangang, he suffered setbacks one after another, and his troops were defeated.

In the end, he really rushed to the top of the mountain in a hurry, but he was besieged by heavy soldiers and waited for arrows. If Chen Qingyun hadn't made other arrangements and sent soldiers and horses to rescue, I was afraid that he Nie Long would have to die on this nameless earth mountain in this battle.

It was also this continuous attack faux pas that made Sun Ning and the others change their tactics, and used night attacks, fire attacks, and even the final surrender to enter their camp.

As a result, it also ended in failure, and the other side was still prepared, so as to resolve all kinds of crises at the minimum cost, and sometimes it was even more able to counterattack and attack, and kill the Vietnamese army by surprise.

If it was said before, Sun Ning still had very little knowledge of Song Qiyun, the general of the Liangzhou Army, and he didn't even know what he relied on to have such a reputation.

After this time, he was really a little jealous and admired Song Qiyun. This rock-solid defensive means alone is enough to give him a place in this chaotic world.

As the saying goes, the good attacker moves above the nine heavens, and the good defender hides under the nine earths, Song Qiyun can be regarded as fully embodying the characteristics of a good defensive general described in the book of war.

This is not only because his defenses are so varied and stealthy that people don't know where they come from until they are triggered. What's more, it is low-key, too many people don't know its ability, and it is truly hidden under the nine places.

When the new offensive of the Vietnamese army retreated again in vain, only adding some casualties, it was Sun Ning, who frowned deeply without worry.

It is difficult to say whether it will be able to break its defensive line if it continues to attack like this, but the morale of the whole army will really be exhausted in this defeat after defeat.

In this regard, Sun Ning was really annoyed, but also a little lucky.

Such an opponent is indeed unprecedented and difficult to overcome. But fortunately, he didn't encounter it until this time, if Song Qiyun was guarding Youxian Pass, he was afraid that he would double his troops, and he would still be rejected from the pass at this time.

"Your Majesty doesn't have to worry, when tomorrow the minister leads another army to rush and kill, he will definitely be able to break through his defensive position and enter the enemy camp!" One of the generals who attacked this time seemed to be assured, and said loudly as if to cheer himself and his subordinates.

Everyone else chimed in, asking for battle, as if they weren't too affected by the setbacks.

But Sun Ning waved his hand: "No, I plan not to attack for the time being." ”

He saw that such an onslaught was indeed difficult to achieve, so it was better to stop for a while.

"So what do we do next? Is that what you look at? Someone said disapprovingly.

"Yes, Your Majesty, their strength is limited after all, and the minister thinks that as long as we attack day and night, in turns, it will always cost the enemy army to be exhausted and the defense is lax! Why don't you just let the ministers fight a few more battles......"

Sun Ning no longer accepted this: "No, if you fight like this, don't say whether it can be done or not, just the consumption of our army and soldiers is extremely serious."

"Don't forget, we have to face not only the tens of thousands of horses in front of us, but also the Liangzhou army behind us. If you run out of sharp forces like this, what will you do to win the next battle? ”

Sun Ning's words finally woke up the generals, and they all showed expressions of deep disapproval: "Your Majesty is very worried, and the ministers are short-sighted. ”

"But Your Majesty, if you don't attack, why should you break the enemy?" Chen Qingyun said vaguely.

Sun Ning squinted at the enemy camp that was still standing in front of him, and said slowly: "Have you forgotten the most critical question, that is, we are not alone. ”

"Huh?" The generals were slightly stunned, and then they all became excited again, "Yes, we have another army on the battlefield of Lianghuai...... This Liangzhou army obviously came down from the Lianghuai battlefield, so our people will inevitably chase after them, and the position where they came must be on their side, or even in the rear......"

Under this thought, everyone's hearts were even hotter, if it was the latter, the chance to break the enemy was too great.

No matter how Song Qiyun's department can defend, it can only defend the left and right sides and the front after all, and its rear will inevitably be its weakness.

As long as their own soldiers and horses attack together from the rear, no matter how good they are, no matter how good they are, no matter how they can adapt to local conditions, they will be hidden under the nine lands, they will also be destroyed and broken in one fell swoop.

So, instead of continuing to consume yourself, it is better to wait for the subsequent changes to happen. And I think they must know that, too, and it's only because of the onslaught on our part that they put these thoughts aside for the time being.

But once there is no longer a need to defend with all your strength, people are idle, and other thoughts will naturally come back. At that time, it may be the result of self-defeat! ”

Sun Ning smiled, sometimes if you want to break the enemy, you don't have to use the strongest attack, and if you ease it slightly, the threat is even greater.

What's more, he didn't intend to let the enemy rest and recharge his energy so happily.

As another night came, although the Da Vietnamese army horses did not make any major movements, they still sent a group of thousands of men, took out drums and trumpets and other musical instruments, and played and attacked the enemy army in a lively manner.

For a time, the fierce sound of drums and trumpets overwhelmed the howling wind, and reached the enemy's camp and the ears of every Liangzhou army soldier......

Some people died, but not completely......
