Double Money Cashback System

"Ding-dong, Money Double-Refund System activating..."

Guo Sheng sat up. What was that?

"Activation successful."

"Who is it? Who's talking?" Guo Sheng stood up and looked around. The small room was silent, with only the sound of cars passing outside.

"Hmm, what's this?" A screen of white mist appeared before Guo Sheng's eyes. He looked at it.

Host: Guo Sheng

Money: 5,600

This is... "System!" Guo Sheng cried out in delight.

"Ding! System function test normal. Binding conditions met!"

"System successfully bound to Host!"

"Congratulations! You are now the sole Host of the Money Double-Refund System. The System is a low-level game system created by a hyperdimensional civilization. Since that civilization cannot interfere with lower-dimensional worlds, you, Host, have ultimate authority over the System."
