[The main character will not become the Saber King; there will only be a few chapters where he/she becomes a girl for fun. I couldn't think of a better name at the time, so I just used this one. The name will be changed after the book reaches 200,000 words. If you mind this, please don't read on. I'm very sorry!]

Hao Cang transmigrated into a two-dimensional anime series and became bound to a 'Popularity System'.

It ranks third in popularity, with a significant increase in the second season's storyline; conservatively, it could reach 10%.

Ranked number one in popularity, unlock exclusive character background modification privileges.

In order to prevent his character from being killed off prematurely, he had no choice but to constantly gain popularity, exchange for various props, improve his strength, and add more storylines for himself.

Soon, a powerful, imposing, and captivating villain was born.

........

Years later, relying on his own 'efforts' and 'talent,' Hao Cang, who had finally reached the pinnacle of the world, stood with his arms crossed, facing the main characters, and delivered his most powerful message.

[Behind the Scenes + Transmigration + Multiverse + Fourth Calamity + System]

What's it like to start as the Heavenly Dao?

Gu Ran wakes up to find himself transformed into the Heavenly Dao of Earth. As events unfold, he learns that a great secret lies hidden behind the seemingly ordinary Earth.

The myths of ancient times are not legends, but true stories that happened in the past.

For various reasons, the ancestral planet shattered and broke into numerous smaller worlds scattered throughout the myriad realms, and Earth was one of the original fragments.

As our understanding of the laws of nature deepens, the unique characteristics of Earth begin to emerge.

Earth is a core fragment of the ancestral planet, capable of continuously devouring other worlds to strengthen itself. Thus, Gu Ran embarked on a path of plundering the heavens.

World War? How about the Fourth Calamity?

A chosen one? Send a transmigrator there, give him a system, seize his fortune, and destroy his destiny.

One after another, transmigrators were sent by Gu Ran to various worlds. Many years later, Earth was besieged by many worlds.

Gu Ran calmly sent a message to the transmigrators from various worlds: Our ancestral planet is in danger, you must return immediately!

Transmigrator Number One: What! It's been so long since I left home, it's time to go back and visit!

Transmigrator Number Two: Anyone who dares to bully my ancestral star, no matter how far away, will be punished!

………………

As the various transmigrators were recalled, the myriad realms watched as powerful beings stood in the void above Earth, looking as if they had seen a ghost.

The army of time travelers: Are you the ones who have offended our ancestral planet?

As the words fell, world after world crumbled and transformed into primordial power to nourish the Earth.

Gu Ran looked pleased: "You're such a good child, you've all grown up..."

How come the Otsutsuki clan had arrived so early? Uchiha Sasuke: This time, I'll be Hokage! Jiraiya: This time, I won't die at Nagato's hands! Uchiha Itachi: I'll help Sasuke clear all obstacles! Hatake Kakashi: I'm never going to be a 50/50 player again! The style of this world is getting weirder and weirder.
