Time and Space Forbidden Items

They are time travellers, we are indigenous. People in the 21st century are about to be invaded. Prior to this, a large number of contraband items from other time and space had appeared in every corner of the world. Our protagonist, Liang Shicheng, originally thought he had gotten a golden finger, but by mistake, he became a space-time police officer responsible for cracking down on contraband in time and space. Then he will encounter all kinds of contraband with weird functions. This is a dangerous job.
