Lord of the Mysteries: I Became the Fourth Force in the Origin Castle

Mastermind behind the scenes, trading across the heavens, crushing opponents with superior information, lighthearted banter

After transmigrating into the mysterious world, Lin En discovers he hasn't landed in an alley in Tingen City. Instead, he is sitting directly atop the Source Castle.

Gray fog churns, the Bronze Long Table stretches across the room, and Klein and Roselle tentatively converse in the distance, completely unable to see him.

He has become the best-hidden fourth force on the Source Castle.

But unlike the others, deep within his Source Castle stands a bronze door.

Beyond that door lies the Myriad Worlds.

Black Zetsu begs to trade for the Marauder Pathway: "I want to steal Kaguya's chakra!"

Master Four-Eyes trades Maoshan talismans for corpse-suppressing potions: "Fellow cultivator, zombies have gotten more expensive!"

Ye Fan kicks down the door: "Is the lord of this realm here? The Primordial Purple Qi is mine."

Tang Sanzang arrives with his four disciples: "Benefactor, there's quite a lot of resentment here. Would you like our exorcism service? Sign up for a membership and get a Tightening-Curse Headband!"

While Klein is still risking his life to reach Sequence 8, Lin En is already using resources from the Myriad Worlds to quietly rewrite the script of an entire epoch.

"Klein, I got your potion formula in a trade with the Primordial World."

"Roselle, I wrote that extra line in your diary."

"As for the Original Creator, someone has started paying rent in the house where you sleep."
