Finding the spirit book2

Going with the driver the four gentlemen arrive to see a distraught Maria. She is waiting in the driveway waiting for them. 

"I'm so glad you are here. When the men stopped working to show us what was found. Some men showed up soon after. They said nothing to anyone and just started standing guard at the statue. So I sent for you to come. They won't tell me anything and I worried that they could be from the government. " Maria rings her hands nervously. 

"Let's first get you back inside. You go wait in the house while we go see what is happening." Shiro motions to the driver to take her inside. 

Once she is inside they walk to the area in question. Walking around the house Seo Jun notices some symbols etched in a few of the stones in the old part. 

"I think we should get one of the uncles to come." He stops in front of one of the stones.

The symbols are ancient and he has no idea what they mean but is getting and odd feeling about them.
