MTL - The Roots of Manga - ~ don't know what to say

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.

Kurt was born to a poor Baronetcy of Arnold. He was a genius pastry chef in the previous world.

If you transmigrate into a cultivation novel, you absolutely have to fight over opportunities with the protagonist! I can’t be Long Aotian, but I can be the female version of him!

Unfortunately, as beautiful of a thought that was, our protagonist was still killed off as a boss by the male lead! Luckily, she reincarnated again and returned to when the male lead was a child! Seeing the little thing, bone thin with a vague hint of domineering flashing on his face, she had two choices:

1. Kill him. See how he’s going to be so overpowered when he’s dead!

2. Take care of him and honorably ask for something in return in the future!

Thinking of the treasures only the male lead could get to, the money crazy her chose to take care of him.

But who would have known that she would accidentally raise this cute and upright little boy into a black-bellied wolf! After he grew up, he used his treasures to seduce her!

“Master, do you want it? Then why don’t you dual cultivate with your disciple?”

Master with tears streaming down her face: If I had known I could get treasures with s*x appeal, why would I have been a boss in my last life!
