Yang Feng still didn't say anything, but just glanced at Yang Chen's wrapped arm.

Qian Lu seemed to understand what Yang Feng meant and spoke: "Yang Chen's strength is unfathomable, far more than the ones he showed just now. Although he seemed to have self-destructed his right arm, his strength is still not to be underestimated. Moreover, he is very cunning and must not be easily believed. Now only when we join forces can we ensure safety."

Yang Feng's eyes flashed, he thought for a moment, and nodded slightly.

Qian Lu saw Yang Feng's actions, a hint of joy appeared in his eyes, but it soon disappeared without a trace.

The four of them quickly walked out of the passage and came to a hall in the city lord's mansion.

There were many people gathered here, most of whom were guards of the city lord's mansion, as well as some managers and servants.

The few people who went out hunting with Yang Chen were also here. When they saw Yang Chen coming in, they immediately walked over.

The young man whispered, "Captain, how is the situation?"

Yang Chen smiled and said, "It's solved!"

Hearing this, everyone in the hall immediately cheered.

Yang Chen asked everyone to calm down and then ordered: "Now everyone will act according to the plan!"

"yes!"

Everyone agreed and left separately.

Yang Chen said to Yang Feng and others: "Let's go too!"

He walked out of the hall and walked towards a remote path.

After a while, several people came to a hall.

At the end of the hall is a stone door with silver patterns engraved on it, emitting dazzling starlight.

At the top of the stone gate, there are several secret words engraved.

A black platform several meters tall stood in the middle of the hall, and an old man in black robe sat cross-legged, practicing with his eyes closed.

The old man looked ordinary, but his face looked a little strange.

A series of silver-white lights emanated from the old man's body and then flew out in all directions, with hundreds of them, and they looked like a hedgehog.

Hearing the footsteps of Yang Chen and others, the old man opened his eyes and looked over, and all the silver light on his body disappeared.

The old man showed a hint of vigilance on his face and asked in a cold tone: "Yang Chen, why did you come here?"

Yang Chen hurriedly said, "The city lord is presided over the blood formation at this time. There are some problems with the formation and blood crystals are needed. The city lord asked me to come and get some."

When the old man heard this, his face changed without any change. He spoke: "Only the city lord recognizes the treasure house, or holds the token of the city lord in his hand, can he open it? Do you have the city lord's handwriting?"

Yang Chen looked annoyed and took out the black token he got from Qin Yang's corpse and said, "Look at me, I was anxious for a moment, and I actually forgot about this matter. This is the token of the city lord."

When the old man saw the token, the vigilance on his face disappeared. He took out a silver key, turned around and walked towards the stone gate.

"Treasure Gate!"

At this moment, Yang Chen suddenly widened his eyes and pointed at the treasure house gate with his fingers as if he had seen something incredible.

The old man's face was already turned and suddenly turned around and looked at the gate.

The gate of the treasure house was closed, and silver light flashed on it, without any changes.

The old man was stunned. At this moment, three strong winds whistled from behind.

Eighteen starlight appeared on Yang Feng's arms, and his arms suddenly doubled in size, and their bodies were golden, looking like two golden arms, stabbing towards the old man.

At the top of the stone pillar, a black crystal was placed the size of a human head.

This crystal is as smooth as a mirror, emitting bright black light, rippling towards the surroundings like black water waves. A strange energy fluctuation can be vaguely sensed in the black light.

Yang Feng felt that as soon as he stepped into the secret library space, the black centipede in his body touched this strange energy, and immediately remained motionless and fell into a deeper sleep.

"Black Stone!"

Yang Feng's heart moved, but he glanced at Yang Chen next to him and did not immediately take action to get it.

Qian Lu also looked at the black crystal, and a trace of surprise flashed through his eyes.

"Do you know Black Stone too? But this thing can only suppress the black centipede and cannot drive it away. Look around quickly to see if you can find a way to remove the black centipede. In addition, please forgive me, the situation outside is changing rapidly now, and we cannot delay here for too long, at most half an hour." Yang Chen seemed to see what Yang Feng and the others were thinking, and said so.

Qian Lu nodded without comment, walked to a counter, and began to search.

Upon hearing this, Yang Feng also withdrew his gaze and began to search around.

There is no way to use demonic energy and immortal power in the hollow realm. Although this place is a treasure house, there are basically no prohibitions or other things.

The search of the three people was progressing rapidly, and soon the entire treasure house was searched.

After a stick of incense, Yang Feng put down a classic book, his face looked a little ugly, and he looked at Qian Lu next to him.

Qian Lu also looked over at this time, his face a little solemn.

The two of them were not relieved by Yang Chen, so they tacitly took over the search for all the classics and asked Yang Chen to search for other items.

However, the two of them looked up all the classics, but they didn't even see the black centipede.

"I have found some useful information here, and two fellow Taoists can come and take a look."

At this moment, Yang Chen's voice came.

Yang Feng and Qian Lu heard this and walked over quickly.

Yang Chen was standing in front of a counter at a corner. A black crystal box about the size of a foot was placed on the counter. Through the translucent box wall, you could clearly see strange insects lying inside, which were black centipedes.

Yang Chen held a black stone slab in his hand and handed it to Yang Feng. Yang Feng and Qian Lu read it quickly.

After a moment, the faces of the two men became gloomy.

The stone slab describes the cultivation method of black centipedes, from birth to growth, and how to plant them into the human body. The records are very detailed, but it is not written about how to remove the black centipedes.

However, the stone slab talks about black stones. Black centipedes are group animals. Each group of black centipedes needs a worm king to command other black centipedes.

That black stone was condensed with the body of the Black Centipede King and was condensed with secret techniques, so it has the effect of suppressing the black centipede.

If you want to suppress a black centipede, it is enough to just carry a black stone the size of a nail on the body.

"You should keep these two black stones, wear them on your body first, and suppress the black centipede."

While the two of them were reading the contents on the stone slab, Yang Chen walked to the side of the black stone and chopped two black stones the size of an egg, and handed them to Yang Feng and Qian Lu.

Yang Feng said: "According to what is said above, it seems that this big piece is not used."
