It was night, and in the alleys of Cloudsdale, a figure flashed out.

This figure was dressed in a black night coat, with a bright scimitar pinned to his waist, and at first glance, this scimitar was not the regulation of the big man.

"Woo-woo-" The dark shadow made an unpleasant sound, it was the voice of an owl.

Because the owl looks like a flying cat, and it is nocturnal. Therefore, the border people and steppe peoples in the north call the owl a night owl.

There is also a saying in the north: 'When a night owl enters the house, he will come for nothing.' ’

The reason why this black shadow who makes the call of a night owl now pretends to be a night owl is the meaning of this sentence. He's going to be a night owl tonight. A night owl who broke into Dahan Cloud City.

Tonight, something is going to happen in Cloudsdale.

As he screamed, several identical voices rang out from all around.

After matching the code, several black shadows jumped out of the surroundings. After they met, they didn't communicate, just nodded to each other.

Then the first black shadow to appear waved his hand slightly, and several black shadows followed him, walking along the base of the wall towards the east of the city.

They walked through the narrow alleys, and after a few corners, they came to a large dark house.

Around the big house, there are also the same black shadows standing guard.

When several people saw the sentry, they immediately stopped and let out the cry of a night owl.

The sentry man immediately looked over and replied. Only then did the crowd appear.

"Gulu Gula tried his best to ...... the words of the Huns, and the words they exchanged were all Hun dialects.

The general meaning is that there are about 200 people who have infiltrated Cloudsdale, and tonight they will divide their troops into two ways, one to attack the blacksmith camp in Cloudsdale and the other to attack the gunpowder factory in the east of the city.

They didn't know what was worth attacking in the gunpowder factory, but they saw that there were heavy guards every day, and there were many warehouses, isolated from each other, and there would be water dragons around each warehouse, and it was obvious that there were things in it that were afraid of being contaminated with fire.

This easily reminds them of Cloudsdale's great killer fire thunder. If you can burn down the place where the fire and thunder were built, it will definitely be a great achievement.

The attack on the blacksmith battalion was because they felt the sharpness of the Han's weapons during the war. Not to mention the elusive flintlock pistol or the military crossbow, just the sharpness of the swallow knife was created by this group of blacksmiths. Now the first thing to do is to eradicate the blacksmith camp.

If possible, they will also capture some blacksmiths alive and let them go to the Xiongnu to make better weapons, so that they can fight the Han Dynasty forever.

The two attackers had already set the direction, discussed for a while, and then went their separate ways.

The two leaders, with two teams of men, began to move towards the blacksmith camp and the gunpowder factory respectively. There were a few others who remained in the big house and did not do anything. After everyone was gone, the men quietly left.

They are the Xiongnu spies who are directly in contact with the Xiongnu.

The few people left behind were all in order to be able to keep in touch with Sima Xiu and provide strategic information to Xiongnu Shan Yu at any time.

The two teams left.

In the darkness of the night, walk through.

A team of hundreds of people, if not well-trained, will definitely make a noise. But this group of people actually marched quietly in the night.

Chengdong, gunpowder factory.

The workers had a busy day, and it was categorically impossible to light a fire at night. I went to bed early.

The soldiers guarding the gunpowder factory also waited lazily one by one. How could anyone attack a gunpowder factory in this cloud city? All the officers and soldiers have been guarding the gunpowder factory very relaxedly.

They thought of themselves as firefighters, believing that the powder factory could only have an accident if it caught fire, otherwise there was absolutely no danger.

It's they who are lazy, leaving an opportunity for the man in black to take advantage of.

They quietly bypassed the soldiers guarding the gunpowder factory and gradually approached the gunpowder factory.

As soon as the leader raised his hand, all the people stopped.

"Get the fire ready." The leaders said in the Hun dialect that their purpose tonight was to burn down the gunpowder factory in the east of the city.

Without this factory that produces fire and thunder, it would be easy to break through Cloud City.

"Up!" The black-clothed man at the head waved his hand, and the whole person's body lurked lower.

But the silence behind him made him feel dazed.

It stands to reason that as soon as he waved his hand, the people behind him should rush over, no matter how much movement he made, and burn the place down in one go.

As soon as the fire on their side is lit, the other team will take off the heads of all the blacksmith battalions.

But now, after he waved his hand, there was no movement behind him.

As soon as the Hun spy led by him turned around, a strong smell of blood wafted into his nose.

What greeted his eyes was a sight that made him creepy.

Behind him, none of the Hun spies who were still lurking with him just now were alive at the moment. Everyone was lying on the ground, blood bubbling from their necks.

All this shows that just now, these people died tragically in an instant.

can kill people quietly like this, and the only thing that this little spy leader of the Huns can think of seems to be ghosts.

The thought of the ghost made his legs tremble.

As a specially trained spy, he wasn't supposed to be a coward, but this guy was scared and turned out to be a fart. He sat on the ground, not even daring to make a sound.

"Ghosts, ghosts."

Looking at the person who was still following behind him just now, his courage was broken. He muttered with a crying voice, and his pants were also wet.

The scimitars on the waists of those dead men were still there, and they died without a trace of resistance. In this case, only the power of ghosts and gods can accomplish it.

The Hun spy led by him was afraid, but suddenly felt a chill on his neck, and a knife light flashed, and he saw his headless corpse.

Then, in the midst of the tumbling of his head, he saw the same man dressed in black, not more than one, and even not a few, all of whom had short knives in their hands.

This was the last thing the man saw.

The other group that attacked the blacksmith camp ended just as badly.

It's just that they didn't die so quietly, and someone found the attacking man in black. The two groups of men in black fought, and originally as the elite spies of the Huns, they had no power to resist in front of the attacking men in black, and they were almost killed instantly.

Looking at the Huns who were dead, a person with perfect proportions took off the hood on his head, revealing a handsome face, which was Han Yan.

"Brothers, we are the special forces of the Great Han. What we trained was not only to kill people behind enemy lines, but also to protect our own people. Tonight was our first fight, and it was perfect. Han Yan looked at the corpse in the ground with satisfaction and said.

"It is the duty of our generation to solve the Huns perfectly." Dozens of men in black had low voices, but they seemed unusually determined.
