A Replacement Bride

Chapter 392 Infrasound

To her surprise, there wasn't anything shocking in the crate. There was only a file. A surprised Katherine met Joaquin's gaze.

Joaquin pursed his lips. "Open it up." For some reason, he had a feeling the content of this file was crucial. It could probably turn this world on its head.

Katherine realized that as well. Her hand started to sweat as she opened the file. And her heart started to race, but she gulped and calmed herself down. Then she opened the file and took a document out. What she saw made her freeze. The title read, 'Infrasound Weapon.' "This is…" She blinked in disbelief and stared at the title a few more times. "This is a top-secret file. I can't believe Grandpa kept it here."

Joaquin saw it as well, and his face fell. He did not expect this. "No wonder he kept this in a place so secret and put us through a few hoops. This is the file for an ultimate weapon. If this gets out, the consequences are disastrous."

Katherine had no idea about how weapons worked, but judging from what her grandfather did and Joaquin's reaction, it must be serious. She stared at the title again and handed the file to him. "You should read it."

Joaquin shook his head. He didn't take it. "This is your grandfather's research. You should be the first to read it. And Area Seven does have research on this weapon."

Curious, Katherine asked, "What is this? Is it that serious? Does it bring a lot of harm?"
