Intro. The world in the story is a cruel intersection between modern reality and a supernatural space called "Dark World" . It all started with a strange version of QQ software - an indelible virus that acts as a mandatory gate connecting users to a mysterious chat group. The administrator entity named Than Chuc holds the power to kill and kill, randomly "roll call" members to start bloody survival games. The core rule is trade-off: the winner receives "accumulated points" , the loser must pay with real life. Score is the ultimate unit, used to buy weapons or "buy characters" - a mechanism that allows completely changing appearance, gender and age. These changes reflect directly on the physical body in reality, causing the boundary between real people and virtual characters to be blurred. A man can take on the appearance of a beautiful, weak girl to disguise and deceive his opponents.
