When a futuristic scientist is transported into the body of a young man in a fantasy world, his curiosity and desire for power push him to pursue magic. In a world without mercy, Leylin has no qualms about doing anything if it means benefits. He is cold, ruthless and calculating, never forming attachments that could impede his ultimate goal…

Honor? Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now.

You want me to help you? What do I get out of it? Nothing? Bye.

Hmm… that guy looks like he might cause me problems in the future. Better kill him before he becomes a problem…

What will happen when an infinite lifespan and a death curse that uses lifespan appear on a mortal at the same time?

The answer is invincibility.

Zhou Yi stood on the top of a mountain, looking up at the sky and laughing wildly: "No matter how innate a god or demon you are, or how acquired a saint, do you dare to take on this death curse that uses infinite lifespan as fuel?"

On this day, all the gods bowed their heads, and all the immortals fell together.

[No system + no heroine + invincible at the beginning + villain male protagonist + darkness]

After Ye Feng woke up from sudden death, he found that he had traveled through time.

The good news is that he came to a world of cultivating immortals and became the patriarch of a top clan.

The bad news is that he is the dark source of hatred and fear for all living beings in this world...

(Note: In the early stage, the protagonist's invincible clone descends to the lower world to kill the enemy. In the middle and late stages, he recovers to his original form and kills people in all the heavens and worlds.)
