Luo Cheng's clinic was still brightly lit.

However, there was no reception, no cleaning staff, and no one in line, as if he was awaiting my arrival.

Just like our previous meetings, Luo Cheng maintained a smile, but different from before, this time the smile was elegant.

"Which Luo Cheng are you?"

"So, you have already guessed it. Both he and I come from the same world as you, but unlike you, we can use patients to transmit information."

"Aren't you planning to go back?"

"Why go back? I'm doing quite well here, and he is doing well over there. Moreover, once you come over, you can't go back. It's irreversible. If you try to force your way back, there would be two consciousnesses in one body, which would mean dual personality."

Seeing my puzzled expression, Luo Cheng suddenly realized, it seems you don't understand thoroughly. He handed me a glass of water and began to narrate.

It turned out there are two worlds, a primary world and a parallel world.

The two worlds maintain a high degree of similarity, yet there are certain differences.

Through Luo Cheng's hypnosis, those of us in the primary world would gain part of the memories from the parallel world.

After that, when we fall asleep or become unconscious, the consciousness between the two worlds would exchange and experience real scenarios.

Initially, the exchange is brief, but eventually, a complete exchange would be accomplished.

And that's why, in the primary world, Wang Leng's motive for murder was revenge, and he denied the fact that his wife and daughter were alive, because at that time, it was the consciousness of Wang Leng from the parallel world residing in his body.

Similarly, Yang Xiao's consciousness also completed a thorough exchange. In the primary world, when I called him, he didn't recognize me because the Yang Xiao from the parallel world had no intersections with either of me.

"There should be more than one parallel world."

Luo Cheng tapped his forehead with his finger. "According to my theory, multiple personalities can prove this point."

"What is your purpose in doing this?"

"Purpose?" Luo Cheng chuckled a few times and looked at Yang Xiao, "You should ask what the purpose of these patients is."

Yang Xiao said vigilantly, "I just don't want to feel inferior because of my voice."

Luo Cheng didn't speak. Instead, he turned his gaze towards me. I sighed, "The Yang Xiao of this world wants a different life. Your goal hasn't been achieved, but his has. My purpose is to investigate Wang Leng's matter, so I came here."

"Yes, everyone has their own purpose. People in both worlds have different purposes. We can only satisfy the purpose of one of them; it's impossible to make everyone happy."

"But I don't want to come here!" Yang Xiao shouted discontentedly.

Luo Cheng spread his hands, "In fact, here, I can also serve you, so you don't have to feel inferior because of your voice."

"What about Qin Jun of this world? What purpose did he have in finding you?"

"He? He's probably just a scum who lost his business, owes a huge debt, and wanted to commit insurance fraud, but never succeeded. His purpose is simple: to escape his current life."

"Did you help him?"

Luo Cheng smiled but did not answer the question. "This is also a real world where you can continue living your lives."

"I want to be hypnotized."

Luo Cheng tapped his forehead again with his finger, "Multiple worlds, are you sure you can return to the original world?"

I was about to speak when suddenly applause echoed through the empty floor.
