Why didn't the king worry, because the king knew that these people in the northern army would definitely not let down their vigilance during the day the next day, and they thought that they would attack, so how could he obey their wishes?

Such a long period of vigilance and vigilance will inevitably greatly reduce the will of the northern army to fight, and when they choose to relax at night, they will be slaughtered like fish without the ability to resist, if the king attacks at this time, his own losses can be greatly reduced, and what is even more terrifying is that the king does not plan to attack, he intends to sneak attack.

When the king first led the soldiers of Xueluo City to take Canglan City, he had already ordered his subordinates to dig a passage under the walls of Canglan City, which was not large, but it could allow two people to pass side by side at a time.

In fact, it is far safer to act late at night than during the day, because the Canglan City area is already the living area of the frozen beasts, and the frozen beasts need to rest at night, especially the terrible frozen beasts, so acting at night will not bring some unnecessary trouble.

Sending the soldiers of Xuelu City into Canglan City in the middle of the night, the northern army in Canglan City should be resting at this moment, just need to find a place for them to rest, and go down with fire, without spending a single soldier at all.

It's not that Wang loves fire, it's just that fire is convenient and fast to use.

……

Stomp Tread Stomp ......

The vanguard troops were carefully screened by Wang, and their steps must be light and their hands must be fast.

There were less than fifty people in total, all dressed in black, and they had already infiltrated Canglan City through the path.

According to the plan ordered by the king, they began to wander around the various areas of Canglan City.

The insects and birds chirping at night seemed to warn the soldiers of the Northern Army, but where could they understand.

"Alas, what do you say this general is so afraid of, we have the walls of Canglan City to guard, even if those traitors want to destroy us, it will not be easy."

"No way, who made him a general."

The two Northern Army sentries were talking to each other, and they both hated the general, after all, the general had been nervous all day, and everyone was tired.

"Those traitors must be resting at night, I don't think there's anything to defend at all, why don't we just take a lazy rest for a while?" A soldier playfully sat down.

"Alas, don't mess around, if we get caught lazy, we'll have to be beaten up by the captain." Another soldier hurried to pull him, the sentry was lazy and a taboo in the army, and it would be a big deal if they were caught by their captain.

"Hey, you're just cowardly." The soldier who was sitting just didn't get up, and he laughed at the soldier who pulled him.

"It's not a question of being timid or not, it's ......"

Poof!

The standing soldier was halfway through his sentence when a blade pierced his chest, splashing scarlet on the face of the soldier who was still sitting in front of him.

A dark shadow jumped onto the sentry stand, and he noticed the soldier who was already stunned as he sat on the ground.

"Oh? There's another one. ”

Before the seated soldier could react from his astonishment, the shadow's blade plunged into his body first.

The chest cavity goes straight into the heart, causing it to stop beating on the spot.

"You...... You guys...... Come...... Come ......"

Poof.

The soldier of the Northern Army who was standing didn't seem to be cold yet, and before he shouted the sentence "Someone", another stabbing blade was inserted into him, this time directly into the neck, and his words could not be shouted.

The blade that went straight into the neck was stabbed by another man in black, and his technique was smooth and redundant, and he looked much more clever.

"Next time, don't take it from your chest, if you are shouted by the enemy, it will not be an assassination."

"Okay, I've learned, I've learned."

The two men in black had a cordial exchange of technology.

……

There is a small forest in the northeast corner of Canglan City, which is the meeting point agreed by the people in black.

The Captain of the Men in Black has been waiting here for a long time.

Sou!

Three men in black walked out from behind the tree.

"A group of reports has found a large number of housing clusters in the eastern area of Canglan City inhabited by the Northern Army."

Then several men in black hurried over.

"The second group reported that a large number of concentrated houses were found in the northern area of Canglan City, where the Northern Army lived, and it seems that there are general-level figures."

"Three groups reported the situation, and a small number of northern troops were found in the middle of Canglan City."

Subsequently, more and more people in black returned in these few minutes.

"The four groups reported that there were only a small number of northern troops in the west of Canglan City, about a dozen people."

"Five groups reported that no northern army was found south of Canglan City."

"Six Sets of Reports......"

……

A total of nine groups of men in black have all returned, and according to their reports, most of the northern army is concentrated in the northern and eastern areas of Canglan City, which is the area they targeted for arson.

300,000 people is a lot, and if everyone were to live in a concentrated area, these soldiers would definitely be very close, so this also brought efficiency to the fire attack.

"You see how well they sleep."

"Hehehe, they'll shout later."

The two men in black stood in a room, and when they uncovered the tiles, they could intuitively see that it was full of Northern Army soldiers.

The house itself was dry wood, and they took out the fire folds that had been preserved for a long time, and mixed them with the combustion liquid that the king had given them.

Click.

Canglan City lit up.

……

Call.

The Great General of the Northern Kingdom was awakened by a puff of smoke.

When he opened his eyes, there was already a bright hall around him, and the firelight brought a huge temperature, and the sweat on his body could not be stopped.

"Someone! Come! He shouted two loud words, but no one answered him.

What's really going on out there?

The door frame was already on fire, and he had to use the quilt to block it and crash into the wooden door.

Boom.

The general crashed out, surrounded by firelight and a slight hoarse cry, as if he was crying for help.

This...... Why is this happening?

"Someone! Someone! ”

The general walked alone in the streets, and the buildings on both sides were completely in flames, and no matter how loud he shouted, no one answered him, so he kept walking.

As we walked, there seemed to be some shouting in front of us, and it seemed that a few people had escaped.

The figure on the street saw the general and immediately pounced.

"General! The fire started, the fire began to spread from the east and north of Canglan City, and now it has burned most of Canglan City, what should we do. ”

"How many people are still alive?" The general asked.

"Now...... It's not very clear now, but it is only known that the soldiers in the central and southern regions have not had an accident, and they are already fighting fires everywhere. ”

"General, what the hell is going on, why did Canglan City suddenly have such a big fire."

"They...... It's definitely them...... It was the rebels who set the fire, for sure. ”

"But how did they get in?"

"I don't know, I don't know." The general sat slumped on the ground with an expression of disbelief.

What is Wang's best at? Having hunted in the frozen ground for so long, he is a good hunter, and what hunters are best at is setting traps.

And Canglan City is a huge trap laid by the king for the 300,000 soldiers in the northern kingdom.
