Blood Trail!

"Unless an entire army division equipped with advanced weapons attacks them. Then you can worry. But if it's just one person or a platoon of soldiers, we have nothing to worry about." Owen continues his words. 

"Alright. I trust you," Reid replied, although his expression revealed his doubts. "But I still need to go look after them even though they are that strong..." he said, tapping Owen's shoulder before leaving.

Reid still needed to find his boss for his own peace of mind. He was worried that if something happened to Tristan, his lady boss would kill him for sure.

At the same time, a soldier, checking the four-meter-high wall covered in vines with barbed wire on top, shouted, "Sir, I found something."

Owen and the others turned to look at him, including Reid, who stopped walking and turned back toward the wall.

"What's wrong?"

"I found a blood trail. But I don't know if it's human or animal blood—"

"Blood trail?"
