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!
