Bab 343: Chapter 343 The Principle of Optics and The Hollow Wall

"Don't be afraid. The woman on the wall is not a ghost. It's just a painting."

"If you don't believe me," Chen Yu added, "you can go over and take a look for yourself."

Hearing Chen Yu say that the woman on the wall was actually a painting, Hu Liang was dumbfounded.

"It really looks like a wall painting…"

Out of her trust in Chen Yu, Zhou Kexin mustered up her courage and carefully inched toward the wall.

She mumbled and reached out to touch the figure on the wall.

Hearing that, Hu Liang and Pan Yueling were emboldened.

They walked over and touched the wall painting.

A moment later, the two of them looked at each other.

It really was a wall painting.

"Dr. Chen, could this painting be made with some special technique that can be hidden on the wall?"

Zhou Kexin quickly figured out the problem that was happening in front of her.

The walls were bare and white.
