Let you be a good grandson, you raise a group of banshees?

Besides, he had already failed today, so there was little point in staying.

He glanced at everyone coldly and said in a cold voice: "I will spare your lives today. Remember, you only have three days to bring back the jade seal. Otherwise... Humph, do you understand what I mean?"

"Yes."

The palace master hurried away with the remaining two men in black.

After they left, Lu Yuan appeared again.

"Fortunately, we left in time, otherwise it would have been dangerous."

Lu Yuan wiped the sweat from his forehead.

Fortunately, he had been alert early, otherwise he would be in danger today.

This time it is really extremely dangerous, and one could lose his life if he is not careful.

Lu Yuan carefully followed the Palace Master and the two men in black. His heart beat faster involuntarily and he took every step extremely cautiously, fearing that any sound would be noticed by the other party.

As he followed, he kept an eye on his surroundings, looking for any cover he could use.

Upon hearing the news, Ye Qianmo and Mo Chen, who were following not far behind Lu Yuan, were also extremely nervous. They knew that this action was related to the life and death of Ye Qianmo's sister, as well as the fate of the entire martial arts world.

Ye Qianmo clenched his fists, his eyes full of anxiety and worry.

Mo Chen remained vigilant at all times, holding his weapon tightly in his hands, ready to deal with any danger that might arise at any time.

"Lu Yuan, you must be careful."

Ye Qianmo lowered his voice and said.

Lu Yuan nodded slightly, signaling them to keep quiet.

The three of them followed the Palace Master and others closely in secret, not daring to slack off in the slightest.

The Palace Master and the two men in black shuttled through the forest, seeming to be very familiar with the surrounding environment. Their actions were swift and decisive, without any hesitation.

Lu Yuan and his friends could only try their best to keep up and not be left behind.

After walking for a while, the Palace Master and others came to a hidden valley.

The entrance to the valley is blocked by dense woods. If you don't look carefully, it is difficult to find that there is a passage here.

The palace master stopped, looked around, and then walked into the valley with two men in black.

Lu Yuan and his companions observed from a distance. After the Palace Master and his companions had entered the valley for a while, they quietly approached.

Arriving at the entrance of the valley, Lu Yuan stopped and carefully observed the traces around him.

"This place looks very unusual, we have to be careful." Lu Yuan whispered.

Ye Qianmo nodded: "My sister must be in here."

Mo Chen also said: "We must act carefully and not alert the enemy."

The three of them walked into the valley cautiously. There was a mysterious atmosphere in the valley.

The surrounding trees were tall and dense, and it was difficult for the sunlight to penetrate through the leaves, making the valley appear somewhat dark.

They walked along a narrow path, keeping an eye on their surroundings.

After walking for a while, they found an ancient castle hidden deep in the valley.

The castle's walls are tall and solid, covered with various mysterious runes.

The castle gate was closed and several men in black were guarding the door.

Lu Yuan and his friends hid in the bushes in the distance, observing the situation in the castle.

"This castle looks heavily guarded. How can we get in?" Ye Qianmo said anxiously.

Lu Yuan pondered for a moment: "We can't force our way in, we have to find a way to sneak in."

Mo Chen said, "How about we find an opportunity and sneak in when the guards aren't paying attention?"

Lu Yuan shook his head: "This is too risky. Once we are discovered, all our efforts will be wasted. We have to think of a safer way."

Just when they were at a loss, Lu Yuan suddenly saw a carriage carrying supplies heading towards the castle.

His eyes lit up: "There is a way. We can disguise ourselves as people delivering supplies and sneak into the castle."

Ye Qianmo and Mo Chen looked at each other and nodded. The three of them moved quickly. They found some worn-out clothes and dressed up as workers transporting supplies. Then, they quietly approached the carriage.

The coachman was a large, burly man who looked very alert.

Lu Yuan and his companions approached the carriage cautiously, trying not to attract the driver's attention.

When the carriage passed by them, they suddenly rushed out and subdued the coachman.

"Who are you?" the driver asked in horror.

Lu Yuan lowered his voice and said, "Don't make any noise, we won't hurt you. As long as you cooperate with us, we will let you go."

The driver nodded helplessly. Lu Yuan and his men hid the driver in a secluded place, and then drove the carriage towards the castle.

When they arrived at the castle gate, the guards stopped the carriage.

"Who is it?" the guard asked sternly.

Lu Yuan said calmly: "We are here to deliver supplies."

The guards checked the supplies on the carriage and found nothing unusual, so they let them enter the castle.

After entering the castle, Lu Yuan and his companions drove the carriage carefully, looking for the place where Ye Qianmo's sister was imprisoned. The interior of the castle was complicated and there were many passages. They did not dare to act rashly and could only observe while moving forward.

"We have to find my sister as soon as possible." Ye Qianmo said anxiously.

Lu Yuan nodded: "Let's be careful not to attract other people's attention."

After they walked for a while in the castle, they suddenly heard a faint cry. Ye Qianmo's heart moved: "This voice seems to be my sister."

They walked in the direction of the crying and came to a closed door. From inside the door came the sound of a woman crying and calling for help.

"It must be here." Ye Qianmo said excitedly.

Lu Yuan pushed the door carefully and found it was locked. He observed the door lock and found that it was a very complicated lock that required a special key to open.

"What should we do? We don't have the key." Mo Chen said anxiously.

Lu Yuan thought for a moment: "Let's see if we can find another entrance."

They searched around and finally found a vent. Although the vent was not big, it was big enough for one person to pass through.

Lu Yuan decided to enter the secret room through the ventilation duct.

He first asked Ye Qianmo and Mo Chen to guard outside, while he climbed up the vent and crawled in carefully.

The passage was narrow and dark, barely enough for one person to fit in. He was extremely careful with every step he took, for fear of making any noise and attracting other people's attention.

After climbing for an unknown amount of time, Lu Yuan finally saw a faint light coming from the front.

He was delighted and quickened his pace. When he got closer to the light, he found that it was a small ventilation hole that overlooked a room below.

The room was simply furnished, and a woman was curled up in the corner crying. It was Ye Qianmo's sister Ye Ling'er.

Lu Yuan observed the surroundings and after making sure that no one else was around, he gently knocked on the iron grille of the vent. (End of this chapter)
