Even Gu Yan was stunned when he heard Zhou Yuan’s words.

But at the same time, Gu Yan looked at Zhou Yuan with fear in his eyes.

Li Ruigang saw Zhou Yuan holding the gun that he had dropped earlier and immediately asked, “Who are you?”

“I’m just an ordinary person,”Zhou Yuan said calmly.

At this moment, Gu Yan and Feng Xiaoran, who had heard the gunshots, ran over. When they saw their wounded comrade, Feng Xiaoran immediately asked, “What’s wrong? What happened? I heard gunshots!”

Gu Yan had already taken out a syringe from her bag and injected a type of red medicine into Li Ruigang and the unconscious Li Hui.

She said, “There is no antidote for this strange poisonous gas for the time being, but the medicine I gave you can temporarily stop the poisonous gas from invading your bodies.”
