Living on an Island? My System Communicates with All Worlds!

Lu Ming accidentally traveled through time and was stranded on an isolated island. He originally thought he was going to cosplay with a savage, but fortunately the system arrived in time. Can it communicate with exchanges from all over the world? I want to have a magical weapon that can kill people thousands of miles away without being visible? Get to know Dongfang Missile. It is not sold individually. It is powerful and most importantly has good visual effects. It is as beautiful as fireworks!
