Chen Qingyu traveled to the ancient world and became the legitimate son of the Eternal Saint King family. At the beginning, he signed in for the great magical power of the Thirty-Six Transformations of the Heavenly Gang and gained supreme talent for cultivation!

But this is just the beginning:

Sign in for the Nine-Turn Golden Pill, Chaos Green Lotus Seed, and Hongmeng Spirit Root. Swallowing them will allow your cultivation to skyrocket and your realm to soar!

Sign in to the Jade Book of Creation, the Book of Yin and Yang, and the Three Thousand Great Daos, and practice as you please!

Sign in to the exquisite Xuanhuang Pagoda of Heaven and Earth. With it, no one can break its defense!

Sign in with Pangu's true body and gain the strongest attacking power to defeat all enemies!

…………

Countless years later, Chen Qingyu sat far away on the long river of time, looking down upon the heavens and the myriad worlds: "You can do whatever you want, I am invincible!"

My name is Lin Yu, an aspiring young man transported by a truck to a world of immortal cultivation. I became a menial disciple of a sect and gained access to a heaven-defying sign-in system! Day 1 sign-in: Invincible cultivation! Day 2 sign-in: Top-tier immortal technique - The Immortal Scripture! Day 3 sign-in: Immortal Sword - The Immortal Executioner! Day 4 sign-in: Max-level alchemy! Day 5 sign-in: Heaven-Slaying Art! ...Invincible from the start. Always invincible, always awesome!

Just as Hongjun was giving a sermon in Zixiao Palace, three thousand powerful men were rushing on their journey for their lives.

The system prompt sound exploded!

[A rare opportunity has opened, host, please make a god-level decision! ]

[Option 1: Go to Zixiao Palace and compete for the Sainthood. Reward: Hongmeng Purple Qi x1!]

[Choice 2: Stay at Buzhou Mountain and refuse to listen. Reward: Perfect Pangu Heart x1!]

"Saint? Not even a dog!" Chen Changsheng decisively chose the second option!

[Congratulations to the host for completing the "Immovable as a Mountain" sign-in. The reward has been issued! ]

[Ding! You have perfectly integrated the Heart of Pangu, and your foundation has been elevated to the pinnacle of the prehistoric world!]

[Ding! You signed in at 'Pangu Spinal Cord' and received 1 Fragment of the Law of Power!]

[Ding! You signed in early at 'Gonggong Crashing the Mountain' and received 1 million innate merits!]

In Zixiao Palace, the Three Pure Ones were complacent about having snatched the cushion and claimed to be the authentic Pangu.

In the witch clan hall, the twelve ancestor witches couldn't sense Pangu's blood essence and were all stunned!

They didn't know that the greatest opportunity in the prehistoric world had already been packed up and signed for by a otaku!

Congratulations to the host for traveling to Douluo Continent. The strongest sign-in system has been activated, and the host has received a novice gift pack. Would you like to open it?

At this moment, Lingyunyun was sitting on the supreme throne of creation in the Douluo God Realm, and a hearty laugh reached his ears. "Hahaha, not bad. In just a few decades, you have become a powerful Golden Immortal Realm expert. You have lived up to my expectations."

Ling Yun didn't panic when he heard the voice. He already had some guesses about the origin of the system. So he asked, "Who is this senior?"

"I am the Shangqing Tongtian Sage, one of the Six Sages of Heaven in the Primordial World, and I am also your system..."

Li Yuan transmigrated to a fantasy world fraught with danger. This fantasy world has countless realms, holy races of the heavens, true immortals of the immortal realm, and evil gods of the cosmos. The human race is merely struggling to survive in the vast universe until Li Yuan arrives!

Sign in for the first month and become a martial arts master!

Sign in for the second month, become a martial arts grandmaster, and change the dynasty!

After four months of signing in, I have become a martial arts saint and suppressed the world-destroying monster!

Sign in for the sixth month and become a Martial Immortal, sweeping away the Void Immortals of the Heavenly Realm!

After ten months of signing in, I have achieved the title of Martial Immortal Emperor, and all the emperors of the heavens and universes revere me!

Sign in for a year, become a true martial arts god, and roam freely in any time and space!

Liu Qingsong transmigrated to the immortal realm, riding a golden dragon, dominating the world and becoming invincible.

You think saving the world has to be a hero? What a joke! I was just casually stepping on an ant at my feet.

You say fate is predetermined, everything is preordained? Sorry, I transcend the Three Realms and am not bound by the Five Elements.
