Ham Dani, a normal student whose hobbies were to read novels.

A young man with an extraordinary mind is off on an exciting adventure when he mysteriously wakes up in the body of a feeble slave-guy in a different, rich in quirks world.

The main character, a selfish jerk, would use extreme means to achieve his goals. However, he never allows his base instincts to overrule his sense of decency. He always pays back both good and bad deeds.

Will his (terrible/excellent) mentality help him make a fresh start? Will he get through misfortunes and hardships of the new world?

“The author wants to kill me! Why else would he plan so many insidious subplots centered around me, an Extra?”This was Han Xuhan's plight since he had transmigrated into a semi-familiar novel.The novel, written by a degenerate author, was truly messed up beyond description. All Han Xuhan had was a system that barely kept him alive from the dangers of this fictional world.But after he survived the introductory arc, the mad author even began influencing that system!Why else would the Quests issued by it be so difficult? Every time a new quest was issued, Han Xuhan could sense the author's killing intent through it!Ding![ Detected that host has met a child of destiny! Issuing Quest: Manipulate her for benefits! ][ Warning: She is a Regressor who knows your plan. And her hobby is skinning people alive. ]Ding![ Detected that host has met a legendary Ring-Grandpa. Issuing Quest: Trade him back and forth among your circle of friends to squeeze out all of his value! ][ Warning: This Grandpa can escape from the ring anytime! He'll refine your soul in hell when he figures out what's going on. ]Ding![ Detected that host has triggered an apocalypse by harvesting too much protagonist halo. Issuing Quest: Kill the harbinger of the apocalypse. ][Warning: His cultivation is three major realms above you. You're never beating him in a fight. ]As the quests grew more and more difficult, Han Xuhan finally decided that offence is the best defence; and so, to combat the author's murderous intentions, he attacked the main storyline itself!“Hahahaha! The author really loves this female lead, doesn't he? Let's see if he can save her from my evil influence! I will radicalize every precious character of his novel!”Soon, Han Xuhan discovered that this might not have been a great idea, because all the favorite characters of the author were crazy!Additional Tags: Time Travellers, Transmigrators, Reincarnators, Regressors, Machiavellian Characters, Ruthless Scheming, Villainous MC, Multiple Timelines, Paradoxes, Extensive Worldbuilding, System, Survival, Yanderes, Overpowered Female Leads, Enemies To Lovers, Villainesses, No NTR or Yuri, Mysterious Past, Bloodlines, Multiple Power Systems, Politics, Older Love Interests, Master-Disciple Relationship, Wholesome Relationships, Kingdom Building.
