The data of NPCs did not include differences between humans and monsters; things like fighting methods and weaknesses were absent. After all, the system still encouraged players to prioritize peaceful negotiations and not try everything to fight NPCs.

Knowing that the other party could not be fought, Feng Bujue felt relieved, put away his weapon, and walked towards the dark figure.

When he approached within two meters of the other party, the dark figure suddenly raised an arm, palm upright, making a gesture to stop.

Seeing this, Feng Bujue stood still, waiting for the other party's next reaction.

The music from somewhere rang in Feng Bujue's ears again, and the dark figure, sure enough, did a zombie dance from "Thriller." He wondered if this was hinting at something…

After dancing for a minute or two, the dark figure did a seven hundred and twenty-degree spin and reached out to push the iron door behind him. On the surface of the door, another invisible magic circle failed, emitting the sound of glass shattering.

Afterward, the Shadow of Dance let out a scream in his unique voice, brushing past Feng Bujue while dancing. As he walked further and further away, the surrounding darkness became increasingly dense.

Feng Bujue now understood that one of the characteristics of the Shadow of Dance was probably controlling darkness. Because he had come to the ground floor, the two floors above had become brighter, and as the Shadow of Dance left, the surrounding darkness would become an unordered, diffuse state.

"Okay… this is the only way." While the surroundings had not yet been completely swallowed by blackness, Feng Bujue took a few steps forward, grabbed the two doorknobs of the iron door, and pushed it open.

The moment he stepped into this final hidden room, Feng Bujue was sure that he had found the source of that disgusting smell. Compared to the putrid odor in this room, the smell in the rest of the house was nothing.

To describe it, it was like someone had farted in this room, and then no one could be seen in the room.

As soon as Feng Bujue took a few steps in, the door behind him closed by itself, making a loud bang.

The light in this room was chaotic and dim. Feng Bujue looked around through his gas mask, first seeing on one side of the wall the synthetic human he had seen before… the one with the lower body covered in knuckles. At this moment, it had been nailed to the wall with many thick iron nails. The wound in its chest, pierced by bone spurs, had stopped bleeding, and the floor directly below it was covered in blood.

The synthetic human with bone spurs growing out of its wrist was lying diagonally in a recess in the wall. There were two iron racks outside the wall that could hold its "hands," and the middle section of the recess was covered with strange moss-like plants, which seemed to be food for those tongues.

Feng Bujue's gaze moved slowly, and he discovered that the area of this room was astonishing, and the height of the roof was also inconsistent with the structure of the house. Obviously, the space inside this door did not exist in the room outside the door.

He roughly glanced around and found that at least twenty synthetic humans were embedded in the walls of this room. They were of various shapes, each of them incredibly grotesque, and just looking at their appearance made one's skin crawl.

"Andrew, is that you?" A woman's voice came from the chaos in front of him.

Feng Bujue followed the sound forward and soon saw a corpse-like woman lying in a certain recess. She only had one eyeball, her skin was dry and ulcerated, she had no hair, her teeth were all black and rotten, and she exuded a stench that was enough to drop one's survival value.

The moment Candice entered his sight, another CG appeared.

…………

"Andrew, my child, don't you recognize me?" Candice asked softly.

Andrew looked at the monster in front of him in horror. He finally understood why Arthur never let him come to this room: "Mom… Mom… No, impossible, you're already…"

"I'm not dead." Candice's voice was full of resentment. "I was conscious until the moment I was buried. It was all Arthur's doing, it was him! He poisoned me to cause my illness, he faked my death! The day after the funeral, he dug me out and used alchemy to turn me into what I am now!"

"But… but why, brother…"

"He's not your brother! He's a Xing clan person! He's the incarnation of a demon!" Candice interrupted, "Look at these synthetic monsters in this room, he has already started killing innocent people, hasn't he?"

"No… those people…" Andrew wanted to explain.

Candice immediately said again: "Don't be deceived by him, Andrew! He's just using you, look at what he did to Mom! Sooner or later, he will kill you too!"

"Then… I… what should I do…"

"You have to be patient, Andrew, you can't kill him now, you have to wait for an opportunity…" Candice lowered her voice, "You have to keep today's events a secret, don't reveal anything in front of him, understand?"

"I…" Andrew was a little at a loss.

"Come here, listen to me, Mom will tell you what to do…"

…………

The flashback ended, and Feng Bujue came back to his senses and was standing in front of Candice.

"Andrew, what happened to you?" Candice looked at Feng Bujue and asked, "Wait… you… could you be Arthur?"

Hearing this sentence, Feng Bujue immediately understood many things, "No, it's me, Andrew." Feng Bujue imitated Andrew's tone.

Candice looked at him deeply again, "What's wrong with you? Did Arthur do something to you?"

"The soul exchange alchemic process failed." While saying this, Feng Bujue took out the "Alchemy Advancement," flipped to the second chapter. At this moment, the content of this chapter was no longer blurred. The system had translated it, and the second chapter recorded a complete alchemy example.

"Failed… what does that mean… where's Arthur?" Candice asked.

"I killed him, and he turned me into this." Feng Bujue's gaze stayed on the book. When he finished speaking, he squatted down, casually dipped some unknown liquid from a nearby stain, and began to draw the alchemy array according to the picture.

"What are you doing?" Candice looked at her son's strange behavior and asked suspiciously.

"I'm saving you, Mom." Feng Bujue replied, "With this alchemy array, I can turn you back into a normal person from a synthetic human."

"Is… is that so…" Candice replied.

"Arthur is dead, Mom, you don't have to stay here anymore, we can go back to our original lives." Feng Bujue added.

"Yes… yes… hahaha…" Candice couldn't help but laugh, "Arthur is dead, Andrew, you are indeed my good son… you really killed that Xing clan demon, hahaha…" She was overjoyed, "I can finally leave this place…"

Feng Bujue quickly drew the alchemy array, moved Candice out of the wall, placed her in the array, and then took out the six items from his pocket one by one and placed them around her.

Candice couldn't wait to say: "Quick, Andrew, quickly activate the alchemy array."

"Why be in such a hurry, Mom." Feng Bujue said in a strange tone, "Are you so eager to get my power?"

"You… what are you saying…" Candice's expression changed drastically, but she immediately covered it up, pretending to ask, "An… Andrew, what are you saying, Mom doesn't understand…"

"Just now, I realized something… I finally understand what Arthur meant by that sentence, 'My silly brother'." Feng Bujue sneered, "Actually, I'm not your son either."
