Three battlefields were fought at the same time, with six armies of 20 million each, and the total strength reached a rare 120 million men.

Of course, the actual battles on the battlefield are only about 300,000 on each battlefield, after all, there are city walls separating each other, and they can't accommodate so many people at once.

The rest of the men were divided into half rests, prepared in the rear, and replenished at any time.

One side is attacking the city at any cost, and it has a posture of never giving up if the city is not broken.

One side strictly guards the city, and has the determination to die in the city.

The battle has been very fierce since the first contact, and the casualties of soldiers on both sides are very heavy.

Although the army of Xiyu Country has undergone long-term training, its combat effectiveness is not low, but after all, most of them are new recruits, and many of them are really on the battlefield for the first time, and their experience is poor.

The army of the Demon Realm has been fighting for many years, and many of them are veterans of a hundred battles, even if Long Xiao Kingdom surrendered, it is also very experienced in combat, so the overall combat effectiveness is naturally superior.

However, the army of the Xiyu Kingdom has the city wall as a barrier, and it is a home battle, so as a defender, it has the advantage of the right time, place and people.

The Demon Realm army is very strong in combat, but after all, it is a siege, and they are far less familiar with this place than the defenders, plus the Demon Realm attack on Xiyu Country is an invasion war, and the common people will definitely not support their actions, and the time and place are favorable.

Their greatest advantage is their strength and their rich combat experience.

As a result, the two sides were always evenly matched, and even the number of casualties was always close, making it a real war of attrition.

This kind of war of attrition is very unfavorable to both sides, because the war consumes a lot of manpower, material resources, and financial resources, and if it continues to be fought like this, it will be a lose-lose situation.

As soon as the siege began, it was a non-stop battle, half on the battlefield, half resting, taking turns on the field, day and night.

After fighting for more than 20 days in a row, the army of the Demon Realm also failed to break through the city, and the number of casualties on both sides on the three battlefields was about 300,000 per day, and the total of more than 20 days was more than 7 million casualties each.

There was no winner in this war, and after more than twenty days, the weather became colder and colder, and the soldiers on both sides became very tired.

However, this is like a gambler betting on the table, when he hits such a situation, Qu Yunyang naturally doesn't want to stop, he paid such a big price, but he failed to break through the city, if he stops, wouldn't he sacrifice so many people in vain?

If the army of the Demon Realm does not stop, it is even more impossible for the soldiers of the Xiyu Kingdom to give up the city, in the same way, the Xiyu Kingdom has paid such a large number of casualties, how can they be willing to abandon the city and retreat?

The siege army is a famous general, and the defending army is also a famous general.

On the other side, after more than 20 days of day and night, the three million people led by Liu Tingfeng had already made a detour to the rear of Qu Yunyang's army.

By this time, the war had been fought for twenty-four days.

Liu Tingfeng, who went around to the rear of the Demon Realm army, did not order a sneak attack at the first time, but looked for a hidden place to rest!

A sneak attack requires timing and a good mental state to have the best effect.

His army marched day and night, in fact, it was also very tired, and it would not take advantage of the sneak attack in a hurry.

The next day, the spy reported that the Demon Realm army outside Wuqu County had about 16 million people who could fight, divided into two teams and attacked in turn, each with 8 million.

After a night's rest, Liu Tingfeng's team had recovered somewhat, and Liu Tingfeng summoned Xiao Bailong and Wu Changkong to his side to discuss the sneak attack.

The three of them surrounded a map that looked a little broken, and Liu Tingfeng pointed to one of the locations and said:

"This is Qu Yunyang's base camp, he is responsible for commanding the siege during the day, and Yuwen Junxiong is in charge at night."

"They rotate at the same time, you say, should we sneak attack while they are in rotation, or will we launch a sneak attack in the middle of the night when the other party's people are resting on duty are asleep?"

After Xiao Bailong and Wu Changkong glanced at each other, Xiao Bailong suggested:

"I think it's better to sneak attack in the middle of the night, it seems chaotic when you rotate, but in fact, it is still carried out in an orderly manner, after all, there are not many people who really go to the battlefield, and more are preparing for war in the rear."

"The effect of the sneak attack must not be very good, it is better to sneak attack their camp tents in the middle of the night, while half of them in the barracks have already fallen asleep, it is best to set fire to the camp, burn their base camp and grain and grass, and kill them while they are in chaos."

Wu Changkong also nodded and said:

"The subordinates are also in favor of the sneak attack!"

Liu Tingfeng thought about it and agreed:

"Okay, then we will continue to rest during the day, and when we arrive at the unitary, our troops will be divided into three ways, outflanked from three directions, and when we reach Zishizheng, we will attack at the same time, and hit them by surprise, and the people who sneak into the enemy camp first are to get rid of those guarding soldiers, and once they are discovered, they will immediately start to set fire to the camp, so that they are as chaotic as possible, and then we will attack in three directions to destroy the enemy to the greatest extent."

Speaking of which, after a pause, he continued:

"Of course, this is not enough, we also have to inform General Baili to cooperate, when the enemy camp is sneak attacked, the siege army over there still has millions of reserves, they will inevitably return to the camp to support, we only have three million people, we will definitely not be able to withstand their counterattack."

"Then, at this time, we need the cooperation of General Baili, he leads the soldiers in the city, while the siege army is back to defend, rush out of the city gate, and pursue the retreating enemy army, we will invisibly form a situation of attacking from all sides, disrupting their formation, and we can encircle and suppress them."

Bai Xiaolong immediately took the initiative to ask:

"It's really not easy to take a detour to Wuqu County, so while you are resting during the day, I'll take a trip myself!"

Liu Tingfeng thought about it for a while, and felt that this matter was really a flying little white dragon, he was the fastest, and it was indeed difficult for others to avoid the demon army and enter Wuqu County, so he nodded and said:

"Okay, then you can run it yourself, go and come back quickly!"

So, Xiao Bailong immediately got up and went to Wuqu County, while Liu Tingfeng and Wu Changkong stayed behind to arrange for the army to rest.

It was night, in the mountains in late autumn, the temperature was very low, and the weather was gloomy, but fortunately it did not rain, otherwise it would have been even colder.

However, although it did not rain, the night was very dark, and the moon was hidden in the clouds.

Liu Tingfeng's three million army was divided into three teams, each with one million, Liu Tingfeng personally led the middle army, Bai Xiaolong led the left army, and Wu Changkong led the right army, taking advantage of the night, quietly outflanked Qu Yunyang's military camp from the three sides.

In Qu Yunyang's barracks, the eight million army was resting peacefully, and many soldiers had already fallen asleep and slept deeply.

If you have to fight during the day, you have to rest well at night, because they have a military camp behind the battlefield, so the defense is relatively lax, the front is the battlefield, there are eight million troops in front of the front, and the back is their own territory, they naturally have no worries, in order to be able to maintain their spirits, almost all of them sleep very soundly.

Even Qu Yunyang himself slept peacefully in the tent in the middle of the barracks.

The night is very cold, the soldiers standing guard outside also try to choose to stand in a relatively sheltered corner, and seem very relaxed, more than 20 days have passed, everyone's eyes are focused on the battle on the front line, as for the rear, that is, their logistics personnel will often send supplies and grain and grass over, there will be no accidents at all.

Therefore, those who stand guard will secretly take turns to rest for a while, and there should be 10,000 people standing guard, but now there are 5,000 people on duty, and 5,000 people are hiding in sheltered places to sit and rest!

As for those who patrolled, they were supposed to turn around once in half an hour, but they all secretly changed it to an hour, and they were just going through the motions.

Because I don't feel the danger, the defense becomes particularly lax.

This created better conditions for Liu Tingfeng's sneak attack.

Liu Tingfeng's three armies each sent five thousand masters to sneak secretly, close to the military camp of the Qu Demon Realm, and quietly eliminated the soldiers standing guard in those important positions.

The army behind cautiously moved forward.

Finally, the time has come.

The 15,000 people who secretly approached the barracks no longer concealed it, but carried out assassination operations in an open manner, quickly dealing with the soldiers standing guard and patrolling.

The movement was so loud that the night watchmen immediately blew the whistle of warning.

For a moment, the sound of whistles immediately broke the silence of the barracks, and almost all the tents had soldiers standing up, ready to assemble urgently and prepare for battle.

However, as soon as the whistle sounded, the masters who had already approached the barracks had already begun to kill people and set fires at the same time.

Liu Tingfeng's three sneak attack armies rushed to the Demon Realm military camp without hesitation, and before the Demon Lord could react, a tragic massacre began.

Before many people could react, they died inexplicably under the sword.

The military camp of eight million people, that is not small, Liu Tingfeng's three teams rushed into the enemy camp, taking advantage of the chaos is a burst of killing, not giving the opponent any chance to react at all.

Qu Yunyang, who was in the middle of the barracks, had already jumped out of the camp tent as soon as the warning whistle sounded, he flew up, and stood on the top of the camp tent at once, and saw that the periphery of his barracks in three directions was already on fire, and the sounds of fighting and screams came and went, and he was already in chaos at a glance.

As a battle-hardened veteran of a hundred battles, Qu Yunyang naturally knew that his military camp had been attacked.

He only looked at it a few times, and he knew the approximate number of sneak attackers, which was only about three million.

There were eight million troops in his camp, and if he didn't deal with it properly and was disrupted by three million people, the consequences would be very serious, so he didn't show any panic, but ordered Yuwen Junxiong, who had just left the camp:

"General Yuwen, immediately gather your generals and let them control the soldiers in their camp, and never allow them to run around, let alone rush to the place where they were attacked, but gather first in the middle ground."

Yuwen Toshio replied loudly:

"The last will obey!"

Yuwen Toshio is also a veteran, so he naturally knows the truth that he can't mess with his own position, so he immediately began to command his generals calmly, began to gather the army, and stood in formation.
