Why did Si Yehan suddenly disappear? Where was that weird phone number from? Also, what was inside this briefcase with its clearly labeled acronym…

Ye Wanwan's thoughts were in a turmoil, so she forcefully tugged the password lock.

Ka-chak…

Ye Wanwan was taken back but reflexively looked down at the lock in her hand. She bluntly ripped the lock off…

This lock… appeared to have been touched by someone…

Could it be that someone already decoded the lock…

Ye Wanwan quickly took out the briefcase's contents before she could think about it more deeply.

"Hypnosis…"

There was a thick stack of documents inside the briefcase with a string of foreign language written on it. Ye Wanwan furrowed her brows. These documents recorded everything related to hypnosis and memory.

This included memory masking and memory recombination, as well as the unfamiliar and difficult-to-understand field of genetics.

Ye Wanwan managed to roughly understand the content based on the introduction and abstract of the documents.

It was a theory on the sequence of A+B memory masking.

Basically, the user would erase Person A's memory and then forcefully mask Person B's memory over the depths of Person A's mind with the method of deep hypnosis.

If Person A's memory was completely erased by the hypnosis method and Person B's memory was forcefully integrated into Person A, then Person A would theoretically replace Person B and become them; even Person A themself wouldn't detect it at all.

Ye Wanwan was confused as to why Si Yehan was interested in this subject.

When Ye Wanwan flipped to the next page, she was utterly dumbfounded.

There was a lot of information about countless girls recorded on the following pages. Every girl was deceased already, but everything about them, from their family background to their growing experience, was recorded very meticulously in minute detail.

Ye Wanwan even saw her own information and file in there.

Name: Ye Wanwan

Gender: Female

Age: 16

Father: Ye Shaoting

Mother: Liang Wanjun

Grandfather: Ye Hongwei

Grandmother: Tan Yilan

Older Brother: Ye Mufan

Family Background: A daughter of the Ye family in China, died in a terrorist attack abroad at the age of 16.

When Ye Wanwan saw her introduction file, it was a shock to both her eyes and her mind. The file contained a detailed record of her and the final statement enclosed stated she died in the terrorist attack abroad several years ago…

Also, at the very end of the file, there was a remark: "Suitable for memory masking."

There was a CD placed at the very back of the file.

Ye Wanwan took out the CD and walked back to the desk. She turned on Si Yehan's computer and placed the CD into the CD drive.

A moment later, a video automatically popped up on the computer screen and started playing.

"Are there any issues?" A man's icy voice was heard.

Promptly after, an elderly man wearing white clothes appeared in the video.

"Ninth Master, we've already studied this project for more than 30 years. There's an enormous risk if it's done with the genetics method, but we've switched it to the method of deep hypnosis. It can accomplish the same result and absolutely won't yield any problems."

"The theory?" the man said.

The elderly man in white nodded and explained, "Deep hypnosis completely destroys the memories of the hypnotized person and everything the hypnotized person experienced will reset. During this period of time, if there aren't new memories masking over the gap, the hypnotized person will lose their self-identity."

"However, if we use the hypnosis method and forcefully inject someone else's memory into the hypnotized person—this action is called memory masking—then the hypnotized person will completely transform into the owner of the memory being injected. Basically, the hypnotized person will undergo drastic changes and completely turn into someone else."
