There’s a Bug in My Shop System

Synopsis: [Transmigration + System + Comedy + Wild Imagination + Cheats]

After unexpectedly transmigrating into another world and awakening a System, he thought he would be invincible from the start. Instead, the System bugged out, left him a shop, and ran off. Luckily, the shop was free to use. One day, the System suddenly returned. After learning the continent's secrets, he led several other transmigrators through the Tang dynasty, the Republic of China, and a world of zombies. Later, a disruption in the space-time continuum accidentally sent him back to the city. But it turned out he was a police officer. After completing the task assigned by his superiors, he began another journey through time and worlds.
