Delta: Sign in to Aerospace and Get a Flying Tank

[Delta+sign-in+big red special effects+genius boy+10*10 safety box] Traveling through the parallel world of the Delta, Qin You awakened to the sign-in system. Signing in within the Delta area can earn special rewards. Since then, Delta has welcomed its master. I signed in at the No. 0 Dam Cement Factory and received the reward "self-aiming headshots". The naked modified M14 in my hand shot headshots one after another. Sign in at the Bakshi Tower of Babel and receive the reward "Full Map View and Transparent World". Why have all the other operators turned into stickmen? Sign in at the launch area platform of the space base and get the reward "Flying Tank". The sky in the space base is the sky of the flying tank!
