Liu Xiao is reborn in the Three Kingdoms period, marrying the most beautiful woman, drinking the strongest liquor, killing Liu Bei, defeating Sun Quan, fighting Cao Cao, and seizing a vast empire. "I'm going to be emperor! Who dares to stop me..."

"Hmm? Under One Person? Finally, a normal world!" The cheat system, over two hundred years late, brought the seventh-rank Gu Immortal Lin Jing to the world of Under One Person after his death. "Just the Eight Extraordinary Techniques! Not interested! Wait… Liu Yiming, chairman of Chang'an Group? Popular idol Lu Xiaolu? Wow, this is going to be interesting!" [Under One Person, countless worlds, time travel. The system is a disguise! Not a system novel! Not a system!] If you, dear readers, find "The Gu Master Starting from One Person" enjoyable, please don't forget to recommend it to your friends on QQ groups and Weibo!

Ling Chen, an outer disciple of the Qinglan Sect, was originally an orphaned youth. However, due to the secret of possessing the Chaos Pearl, he became a thorn in the side of Xu Gang, the sect's Supreme Elder, and Zhao Wuji, a henchman of the Punishment Hall. He was also coveted and hunted by Yan Jin and Jin Lie, the prodigies of the Burning Flame Valley and the Golden Sun Palace. After being falsely accused of stealing the Earth Core Flame Marrow, he became a "traitor" wanted by all nine sects. The sect abandoned him like trash, and his former fellow disciples turned against him. Only Ye Qingmei, the illegitimate daughter of the Ye family in Medicine King City, used the business world as her weapon to secretly pave a path for him to survive in the cracks of family infighting, becoming the only warmth he had in his desperate situation.

In a desperate situation, Ling Chen accidentally fell into the Black Annihilation Swamp, but awakened the Chaos Sword Body within the ancient cultivator's tomb, obtaining the ancient inheritance "Chaos Devouring Heaven Technique"—this technique can devour the spiritual power of the five elements to strengthen itself. Combined with the "Nine Strikes of Sky Rift" and "Flowing Cloud Illusionary Step" that he comprehended, he can sever stars and create afterimages, and his sword energy can shatter the void. The Chaos Pearl he carries with him holds even more mysteries. Not only can it conceal his aura, but it also awakened the ancient "Ten Thousand Paths Sword Diagram" fragment when he was on the verge of death, triggering the secrets of the heavens and allowing him to glimpse the supreme sword intent of "pursuing cause and effect" and "the rise and fall of ten thousand worlds in a single thought."

After escaping the swamp's desolation, Ling Chen embarked on a path of "one man, one sword, battling the heavens": In the Xuanwu Valley secret realm, he used a remnant formation to conceal himself, seized five elemental spiritual treasures, and turned the tables on the Foundation Establishment peak prodigies who were besieging him; to protect Ye Qingmei, he pointed his sword at the Medicine King City families, using the ultimate sword intent that could shatter all laws to break the "bloodline determinism," intimidating all forces. As his cultivation improved, he gradually discovered that the pursuit by the Nine Sects was merely the tip of the iceberg—beyond the Qingli Territory, alien races had already laid a conspiracy, and ancient grudges and a cosmic-level calamity were quietly approaching.

What's the first thing to do after landing?

Looking back on Li Yuan's legendary life, he achieved countless accomplishments and defeated numerous enemies. But the turning point in his life was Roger's words after he traveled through time: "Hey kid, wanna board my ship?"

"Great, at least it's much more interesting than staying in this lousy place."

But after boarding the ship, Roger was surprised to find that there was an incredible monster on his ship!

...

Years later, facing a group of new-era pirates, Li Yuan uttered those world-shaking words: "Want to know what One Piece is? I'll tell you! ^_^"

[Ding! Invincible Cultivation System successfully bound!]

Chen Nuo unexpectedly transmigrated to a fantasy world, and the system sounded as soon as he opened his eyes.

[Do you want to activate invincibility mode with one click?]

"Open! Open it now!"

The next second, Chen Nuo's cultivation surged violently!

Qi Refining stage? Break through in an instant!

Nascent Soul stage? Disdain!

Half-Emperor? An ant!

True Immortal, Eternal Emperor, Chaos Ruler, Primordial God Lord... until the invincible realm!

The entire hierarchy of the immortal realm is as flimsy as paper in front of him!

During the sect competition, when his opponent unleashed the pressure of a Void Refinement stage cultivator, Chen Nuo yawned and said, "Is that all?" He casually slapped the opponent away!

During a secret realm adventure, a Saint King-level monster blocked their path and tried to rob them. Chen Nuo picked at his ear and said, "Shut up!" He then kicked the monster over!

In the midst of a dynastic struggle, a powerful emperor-level expert personally exerted pressure. Chen Nuo stretched and said, "Get lost." The other party was so frightened that he knelt on the ground!

While others may spend thousands of years cultivating to break through to a higher realm, Chen Nuo can simply move his hand and stand directly at the top of the world!

"Everyone says cultivation is as difficult as ascending to heaven???"

Chen Nuo looked at all the trembling powerhouses at his feet and smiled faintly:

"Sorry, I've been invincible since the day I transmigrated here."

Out-of-character (OOC) setting reworked. If you dislike this, please do not read. This is my personal take on the Shadow, a powerful being. Read this fanfiction without thinking. Also, the Shadow is not the male lead; he is a higher-dimensional god.

"We are those who lurk in the shadows of the Shadow Court, hunting down the shadows."

"Twilight has fallen; the time for reckoning is approaching."

"I am the shadow, and the one who lurks in the shadows to hunt the shadows is the master of the Shadow Garden."
