Chapter 100: "The Secret of the Blueprint-3"

After an hour, the UV light was brought by the courier service inside a food box carton. 

Upon unpacking, Harold immediately plugged it into the power outlet. When they turned it on and hovered it near the blueprint's surface, they were shocked.

What their eyes and the handheld microscope didn't see a while ago were the scribbles and drawings that could only be visible under UV light!

"Amazing…" Harold gaped as he saw what his father did to the blueprint. "So this is what he meant by 'magic'…"

"Witty," Sanno said, forming a subtle smile. He's relieved that the architect left a clue for them. Harold's father might know that his life would be in danger soon that was why he told his son those negative things about D.M. Cadre and Amanda Hiddleworth.

Harold slowly panned through the blueprint, starting from the bottom part. "Can you take the pictures while I hold the light?"

"Sure."
