I Transmigrated into a Book to Invest in the Heroine: Oh No, I’ve Raised Them All into Yanderes

[Transmigrate into a book + raising and training + invincible power fantasy + fiercely protective big brother + yandere pursuit + love polygon + lighthearted comedy]

He transmigrates into the book as Zhang Lingtian, the senior disciple and a villainous scapegoat guilty of countless crimes.

From the very start, he is gripping the future Demon Lord Empress by the throat, about to toss her into the Ten Thousand Snakes Pit to be devoured alive?

Thinking of how she’ll awaken her Demon Lord memories and powers one day, then rip out his soul and burn him alive as a living beacon, Zhang Lingtian is scared out of his wits.

Luckily, the [Villain Investment Rebate System] activates instantly!

As long as he gives the heroine opportunities, he can not only change her tragic fate, but also receive an incredible reward worth up to ten thousand times his investment!

To stay alive, he keeps up his vicious persona by saying cruel things to her.

Behind the scenes, though, he showers her with resources and protects her with all his might!

He feeds her ten-thousand-year-old spirit herbs like candy.

He gives her peerless cultivation manuals as if they were scrap paper.

He thought that once he became invincible, he could retire in peace. Then everything took a sudden turn!

His meek junior sister pins his ankle down with an iron chain, her eyes blood-red. “Senior Brother, if you dare look at another woman again, I’ll kill everyone in the world!”

And that’s not all.

The gentle, kind junior sister who had once been his ideal woman comes at him with a bloodstained sword.

His cool and peerlessly beautiful female master lays a vast net, then corners him with nowhere to run!

Seeing all the heroines go yandere and lose their minds over him, Zhang Lingtian feels his scalp go numb. “Help! I just wanted to stay alive and become invincible. How did you all become yanderes?!”
