Long Hui also thought the same. It was an unexpected place to sell and buy drugs. However, since they already spotted the activity, they needed to catch them.
"What do you plan to do?" Yu Qi asked.
"Hmm... We need to inform someone about the catch." Long Hui said.
"But if we leave right now, their transaction might already end." Yu Qi said.
Long Hui took out a square black thing and showed it to Yu Qi. Yu Qi tilted her head.
"What is this?" Yu Qi asked.
She had never seen something like that. It was just a black square.
"I will use this thing to contact the nearby military ground. It is like an emergency telephone. It used Morse code. The morse code would be sent to the military and someone would translate it. They would send a team later." Long Hui said.
Long Hui quickly tapped on the black square. The situation had been sent through the morse code.
