In the flickering firelight, Lin Yinan spotted the tokens tied to the waists of the two men.

She recognized the token; it was exactly the same as the one carried by the barbarian she had killed in the mountains.

They are Hu spies!

Hu spies have infiltrated Sword City!

After the footsteps faded into the distance, Lin Yinan patted her pounding chest, her mind racing.

"Little sister, who were those people outside just now?" Lin Yiheng asked in a low voice.

“Those two are Hu spies. Brother, you stay here and wait for me. I’ll be right back.”

Lin Yiheng guessed what she was thinking and quickly pulled her back.

"You're insane! Those are ruthless barbarians who kill without blinking an eye!"

"Brother, I know what I'm doing and I won't put myself in danger."

Seeing the determination in her eyes, Lin Yiheng could only say helplessly, "Be careful!"

Lin Yinan nodded solemnly, turned around and leaped over the wall, chasing after the two Hu people who had left.

The original owner had practiced internal martial arts, making her light and agile, and extremely fast, allowing her to follow the two Hu people silently.

After passing through three alleys, the two pushed open the door and entered an ordinary residential house.

Lin Yinan pressed herself against the outer wall and listened for a while, but couldn't hear anything. There was no one around. She walked to the house in front, gathered her strength, and climbed onto the roof.

I crept quietly from the rooftop toward the Hu people's house. The front yard was deserted and pitch black, no wonder I couldn't hear a sound.

There was a small courtyard behind the house, where three horses were tied up.

Lin Yinan spotted the house where the Hu people were at a glance, where a faint light shone through the paper windows.

She lay on the roof, peering down through the gaps in the tiles.

Five foreigners were sitting around a table, writing and drawing on a piece of leather, chattering away, seemingly discussing something.

Lin Yinan glanced at the drawing on the leather; it looked like a two-dimensional diagram.

The Hu people are planning to cause trouble in Jiancheng. To ensure that the people of Linjia Village can leave the city smoothly tomorrow, she plans to kill these five Hu people.

A Hu person who can act as a spy must be quite skilled; she has no chance of winning against five opponents.

Lin Yinan is someone who knows when to back down. She silently put away her crossbow; if she can't do it openly, she's better at doing it covertly.

With a slight shift in her gaze, she came up with a solution that required no effort whatsoever.

Lin Yinan took out a highly concentrated, colorless, and odorless sleeping pill from her spatial storage and threw it into the center of the table.

The sleeping pills scattered instantly when they landed on the table. One of the Hu people thought they were flies and tried to swat them away, but he fell to the ground.

Seeing that something was wrong, the other Hu people all got up, but as soon as they raised their heads, they all fell to the ground with a thud.

A single, fly-sized dose of this highly concentrated sedative is enough to incapacitate an elephant.

It is an essential item for robbery and plunder.

After a while, when there was no movement from the other houses, Lin Yinan jumped down from the roof and a dagger appeared out of thin air in his palm.

She first slit the necks of each of the Hu people on the ground, and soon the floor of the room was stained red with blood.

She jumped back two steps in disgust to avoid getting the bloodstains on her shoes.

The leather on the table where the Hu man had just written and drawn was covered with frames and triangles, which were completely incomprehensible.

Never mind, she should go collect the supplies.

From the other two rooms, Lin Yinan found two large carts of high-quality furs. She guessed that these spies might have disguised themselves as fur merchants and infiltrated Jiancheng early on.

They also found two bags of grain, more than a dozen jars of wine, and some knives.

Looking at the three sleek horses in the backyard, Lin Yinan was very tempted, but her spatial storage couldn't hold living creatures, so she couldn't take them with her.

She was someone who knew how to make choices; she didn't dwell on things she couldn't take with her, and simply put all the best materials into her space.

Lin Yinan searched all the houses before leaving.

As soon as her figure disappeared around the corner at one end of the alley, several men in black appeared at the other end.

Yun Qi was skilled at tracking, and led Yun Mo and Yun Wu to the house where Lin Yinan had just left.

"Master, I've investigated thoroughly, this is the place," Yun Qi said in a low voice.

Yun Mo was about to turn over and go into the house.

With his keen sense of smell, Yun Wu twitched his nose and reached out to stop him.

"Something's not right, there's a bloody smell in the room."

"I'll go take a look."

After Yun Mo finished speaking, he leaped onto the roof and immediately saw the room that was still lit up. He drew his sword and rushed toward the room.

Two henchmen kicked the door open, and a strong smell of blood hit their noses and mouths.

Upon entering the house, one sees five Hu people lying haphazardly on the ground.

Yun Qi stepped forward to examine each item and quickly came to a conclusion.

"Master, there were no signs of a struggle inside the room. All five people died from blood loss after having their throats slit with a single knife."

Yun Wu carefully smelled the leftover food and drinks on the table, his face full of disbelief.

No drugs were found in the food or alcohol.

There were no signs of damage to the doors and windows either.

Yun Qi muttered to himself, "These five Hu men were all highly skilled. How did he manage to kill them all without making a sound?"

“These five people were clearly unconscious when their throats were slit. The assailant was ruthless and killed them with a single blow,” Yun Mo said.

Lin Yinan: You wouldn't believe me even if I told you, it's all high-tech.

Yun Mo was also puzzled, so he picked up the picture on the table.

"What else is in the other rooms?"

The two men acknowledged their orders and left.

Yun Mo looked at the map in his hand; it was a defense map of Sword City.

Before long, Yun Qi and Yun Wu returned to report.

"Master, the other rooms are empty."

"There are three horses in the backyard, but strangely, there is no hay for them to eat."

Yun Mo put the map back on the table and said to the two men, "The intelligence that the Hu spies found is still there. Go and lure the soldiers over here."

The three then left the house.

Lin Yinan returned to the house where Lin Yiheng had stored the grain.

Turning over and entering the yard, Lin Yiheng asked warily, "Who's there?"

“Brother, it’s me!” Lin Yinan said in a cold voice.

"How are you? Are you hurt?"

Lin Yiheng held the tinderbox and nervously looked her up and down.

A warm feeling welled up in Lin Yinan's heart.

"I'm fine, let's leave here first."

The brother and sister drove their open carriage back the way they came.

On the way, Lin Yinan downplayed the seriousness of the matter, concealing the murder, and told Lin Yiheng about the Hu spy.

Lin Yiheng broke out in a cold sweat. "When I get back, I'll tell the clan chief and the village chief that we'll set off first thing tomorrow morning, or something might happen."

Lin Yinan felt somewhat relieved; although her older brother was a bookworm, he was someone who could see the situation clearly.

Knowing this situation, these ordinary people were unarmed and could not even save their own lives, so naturally they would not dare to fight against the powerful and well-equipped barbarians.

Back at the camp, Lin Zhaohui noticed that the wagon only carried a sack of grain, and a smug look flashed in his eyes.

I thought he bought a lot of grain, which is why he didn't put it with them, but it turned out he only had a single bag.

"Brother Yiheng, you're back."

A young man with a clear, melodious voice, handsome features, and a tall, slender figure, dressed in a blue robe, strode towards them.

When he saw Lin Yinan sitting next to Lin Yiheng, his eyes lit up.

“Sister Anan”.

That address of "Sister Anan" carried a touch of affection.
