Only Sense Online - Volume 8, Prologue - The Inside Body Dungeon and Parasitic Insects

You Liangxing would never open the speech function in game.
That was because his voice was…
Particularly! Kittenish!

But there was one day, he queued up with a teammate who had so much to say that they may as well explode. Vexed to the point of no return, he contributed a voice that was capable of splitting heaven and earth, “Don’t BB.”
The other party who was being scolded stilled. In the ensuing silence, he suddenly let out a long, relishing… Moan.
You Liangxing: “…..”

Later —
He realised that the person was a great god,
Much later,
Without him realising,
He became the great god’s royal healer.
…. And also his boyfriend.

In an inaccessible village, there were a few houses on the hillside.

People from far away were attracted here and the mountain road was crowded with luxury cars, because, in this town, there was a young man with incredible medical skills who could cure all kinds of illnesses!

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.
