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!]

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

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!

Chu Feng traveled to the world of martial arts and became the seventh prince of the Daxuan Dynasty.

Because he had no background, he was exiled to the northern fortress. Many years later, he trained an army of 100,000 lions and wolves, resisted 200,000 elite troops of the enemy country, captured the enemy empress alive, and became famous throughout the world.

Unexpectedly, an imperial edict promoted Chu Feng to Prince Sanzhu, recalled him to the capital, and re-involved him in the fight for the throne.

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..."

In the 35,800th year of the Great Zhou Dynasty, the feudal lords rebelled, and demons breached the capital. A peerless demon king attacked the Heavenly Prison, seeking to rescue the demons suppressed within.

"Who dares to cause trouble in the Heavenly Prison and disturb my peace?!"

Within the Heavenly Prison, Zhong Changsheng, who had been signing in for hundreds of years, opened his eyes. A peerless blade of light cleaved through the mortal realm. At the same time, the phantom of an ancient divine elephant, towering to the heavens and standing on the boundless purgatory, appeared and crushed the Demon King with a single step!
