The entire globe has transmigrated overnight!

In Japan of 1992, just after the economic bubble burst, society's public safety began to deteriorate. Xu Tianze finds himself transmigrated into the body of a detective named Aoyama Hidenobu, and the moment he opens his eyes, he discovers himself bound up tightly...Entering the new century, a prestigious magazine proclaimed that although Japan has lost a decade since the 90s, they gained a legendary figure like Aoyama Hidenobu.Regarding this, some Japanese nationals expressed: 'Damn it! We'd rather lose another 100 years than have this traitor to our country!'This book is also known as 'This Tokyo is Somewhat Hot.'PS: The protagonist is a rascal, acting with contempt, decisive in killing and fighting, purely for the thrill, not for the faint-hearted.
