Upon waking up, I found myself transported to the primordial world, where the five elements of primordial energy took human form.

On the path of cultivation, Lin Xuan sought opportunities, comprehended the laws, and ultimately became a Primordial Golden Immortal!

[This book is a slow burn in the beginning] + [Please refrain from negative comments if you disagree]

Nuwa: Fat Cat, you can usually bully those innate divine beasts and innate gods who have no backing. Who told you to insult the saint?

Don't you know your own capabilities?

Fat Cat, I don't mind if you usually go fishing, catching birds, or raiding bird nests, but who told you to go and catch Kunpeng and Dijun, and plunder the dojos of the primordial gods?

Nuwa: Fat cat, you're getting upset just because I said a few words to you.

Fat cat, why are you raising your paw? Are you going to hit me?

Bai Chen: Meow meow, I, the great god Bai Chen, love to reason with others and persuade them with virtue!

The innate gods' faces darkened, because Bai Chen's principles and morality could lead to death!

The sacred flame shines brightly!

All my disciples, meow meow meow meow!

Su Han transmigrated to the prehistoric world and found himself becoming Nuwa's thought, calling himself "Emperor Nuwa" and awakening a god-level choice system.

Choose to help Nuwa create humans, and you will be rewarded with top-tier innate divine roots.

Choose to let Nuwa establish the Human Religion and govern the human way, and you will be rewarded with the Chaos Spiritual Treasure, the Primordial Creation Sword.

Choosing to help Houtu establish the Six Paths of Reincarnation will reward you with the innate treasure, the Six Paths Merit Plate.

...

Heaven is ruthless, and sages are unjust, treating all living beings as straw dogs.

I am Nuwa's one thought, I am the Holy Father of the Human Race, I am the Lord of the Human Way, looking down upon the world, turning my back on all living beings, and suppressing all the saints of the primordial world!

Hongjun: "??? This is truly defying the heavens! I, the sovereign, am actually no match for Nuwa's mere thought!"

Nuwa: "No, I can understand if I thought he was a man, but why is he so rebellious?"

"Rebellious is one thing, but even stronger than me, the original self?"

...

Cheng Yan transmigrated to the Douluo Continent with a system that allows him to designate others to bear the side effects of whatever he does. What? This martial soul can bring the dead back to life, but to practice it, one must first… No problem, I'll handle the miraculous healing, the rest is up to Dai Mubai! What? This soul skill can greatly increase one's charm, but the side effect is becoming Tang San? No problem, I'll attract Ning Rongrong and Zhu Zhuqing to confess their feelings, Tang San will bear the side effects, since he's already Tang San! What? This soul bone can make one stronger, but it will ignite one's desires? It's okay, Ma Hongjun was crippled for having evil intentions towards Liu Erlong, it's not like I…

[Absorbing and evolving, invincible, system, decisive in killing, transforms into a white-haired catgirl, no romantic pairing, the entire story is primarily in cat form]

Evolution: I ate myself into a catgirl.

Xu Feng unexpectedly transmigrated to the world of cultivation.

It became a little civet cat.

At the start, it almost became fish food.

In this world where demons roam freely and immortals reign supreme, it felt that the future was bleak.

Fortunately, I obtained the system panel, which allows me to evolve infinitely by devouring others.

Since that's the case.

Xu Feng was the first to devour the fish demon that was preparing to rebel against the Heavenly Gang.

Do roadside weeds give evolution points?

eat!

...

Are the mice in the valley plump and delicious?

Eat, eat, eat!

...

Elixirs and miraculous herbs?

Let's keep eating!

...

Through his diligent absorption of the nutrients, Xu Feng finally reached the Golden Core stage.

"But someone tell me! Why did I turn into a catgirl???"

Li Ge was struck by lightning and reincarnated into the Marvel universe. When he unraveled the mystery of his birth, he awakened his mutant abilities.

Design everything! Manifest everything!

Having drastically modified elements from various fantasy worlds of his past life according to his own ideas, what kind of upheaval will Li Ge cause in this chaotic world by spreading all of this?

(The timeline is based on the needs of the plot)

Multiple female protagonists + invincible + main system of daily check-in with a secondary system of return + protagonist's sixth-hand behavior

The protagonist, Hoy, was originally an ordinary Meituan deliveryman on Earth, wearing a yellow robe. During one delivery, he had a close encounter with a car traveling in the wrong direction at high speed. When he woke up, he found himself transmigrated into a Marvel universe—a universe he didn't know the exact number from—thus beginning his invincible journey.

"I am invincible in the world, why should I practice the Way of the Loser?"

"Billions of beings are nothing but ants before me!"

Su He returns to the real world with the help of the laws of time and space,...

(The first thirty-odd chapters are more slice-of-life, and the female lead's storyline ends there. After entering the elite training camp, things take off and get better!)

Lin Yan transmigrated to the world of "Swallowed Star" and obtained a treasure called "Yan Dao Disc" with deduction and analysis functions.

then........

Deducing basic sword techniques → One slash to slay the god of the wilderness

Deducing basic body movements → One step, one universe

Deducing defensive secrets → Counter-attack leads to enemy's self-destruction

...

Many years later.

"Being invincible is so lonely!" Lin Yan looked at Yuan and the other Hunyuan lords, then at the Hunyuan progenitors, and couldn't help but sigh.

Zhou Yu, who traveled through the world of the Wilderness for three million years, gained the ability to simulate the heavens.

Whenever you kill enough creatures, you can draw a simulation opportunity and randomly perform a life simulation in the world. If the simulation is successful, you can obtain a real avatar and special rewards.

With repeated simulations, finally, Zhou Yu's clones spread all over the heavens...

PS: The order of the simulated worlds is tentatively set as "Devouring the Starry Sky", "Chronicle of the Great Desolation", "Lord of the Snow Eagle", "Panlong", "Cang Yuantu", and "Professional Player of the Universe", but the plan may not keep up with the changes, and everything depends on the situation.
