As Silas rushed towards them, he controlled the earth around him and the air around him, simultaneously.
Though it might seem impossible for air to exist in the underground arena, but matter is anything that has mass and occupies space, and Silas is a matter manipulator. This allows him the ability to control matter at whatever state it's in.
Silas controlled the air around him as he rushed forward, coating them around one of his hands.
He arrived in front of his first target, someone who immediately got scared with Silas' appearance in front of him.
Silas didn't give him time to react as he pushed the air coating his hand to his and punched hard at the location of the person's chest.
His hand didn't make any contact with the person, but the result was that the person was sent flying, across the underground arena and landing on others, eliciting multiple painful groans.
