[Darkening System + Invincible + Extremely Satisfying + Unforgiving + Demon Lord]

Having guarded the Imperial Pass for a thousand years, all Qin Ziming sought was for his wife and daughters to live peacefully and for humanity to enjoy lasting peace.

Therefore, even though the system kept saying that turning into a demon would make him an emperor, he chose to ignore it.

Until her daughter Qin Yuan's blood-written letter flew in front of her.

"Father, where are you? Mother has switched to the path of ruthlessness and no longer wants Yuanyuan."

"They're so mean, they even tried to dig out Yuanyuan's bones! Daddy, Yuanyuan... I miss you so much!"

Qin Ziming was stunned. He had risked his life to guard the Imperial Pass, and yet they turned their swords against his daughter?

Guarding it for a thousand years, only to be met with ingratitude! If that's the case, let whoever wants to guard this Imperial Pass guard it! He returned to the vast heavens to seek justice, but all he received in return was endless insults.

On this day, he completely turned to the dark side, leading his daughter into the abyss of evil...

...

Thirty years have passed, and his daughter has grown into an empress, while he has become the Lord of the Demon Abyss, feared by all.

On this very day, all races broke off relations and invaded, and the heavens were completely overrun.

Those old acquaintances panicked and began searching for him all over the world, weeping and begging him to send troops to quell the unrest once again...

Lu Qingyun transmigrates to the Great Wilderness World and becomes a member of the top-tier Lu family, with an invincible background!

He awakens a system with billions of layers at the start, and his first baptism brings him a crazy boost, crushing all the peerless geniuses and becoming part of the Lu family!

With unlimited resources and energy points, his cultivation level is skyrocketing every moment!

All cultivation techniques and supernatural abilities will be automatically collected!

With a simple tap, you're instantly at max level!

This was a glorious golden age, but Lu Qingyun's appearance made everyone in this age pale in comparison!

......

The ninth ancestor of the Lu family exclaimed, "I was wondering if he was just a mortal? How come he even shattered the sacred bodies of the older generation with a single punch!"

The most ferocious beasts exclaimed, "This Lu Qingyun is inhuman! He keeps talking about sustainable development, but he comes here every day to plunder our flesh!"

A certain immortal emperor, who reigned supreme for eternity, exclaimed: "That's right! Isn't this just a little brat at the Blood Transformation Realm? How come I coughed up blood after being punched by him? Could it be that my title of Immortal Emperor is fake?!"

......

Years later, Lu Qingyun, who had accumulated billions of lives, finally achieved perfection.

"The next realm: countless worlds!"
