This almost meant that out of the four of them, only one would survive.
It would be too late for the ones after to pass through the gap as the poisonous gas would have already arrived by then.
At this moment, Sun Ren and Lu Hua were at the forefront of the four.
Lu Hua didn't even think and immediately rushed forward.
If they were fast enough, it was possible for two people to pass in time, but it was just a possibility.
Seeing that danger was getting closer and closer, Sun Ren gritted his teeth. Then, he grabbed Lu Hua and threw him behind him.
"Hey, brother, what are you doing?"
Lu Hua was shocked. He never thought that Sun Ren would make a move on him.
At this moment, Sun Ren's face was cold as he said, "I'm sorry, only one person can survive, and that person must be me!"
