MTL - Plane Source Code - ~ Plan

The old man pointed to the flower-like woman and said, “Call her mother from now on.” He then pointed to a flower-bud-like girl and said, “This is your sister.”

My younger sister was not cute.

She was arrogant, taciturn and weird, but she knew how to please our parents.

She was two-faced and deceitful, but it seemed like she only treated me that way.

I cared for her, tried to please her as much as I can, but she still disliked me.

Until one day, I found out her secret, our relationship began to get a little bit weird…

World DescriptionA sprawling, untamed cosmos reshaped by the Supreme Empress, a cosmic entity poised to ascend to an unknown plane. Before leaving, she transformed her cosmos into a merciless proving ground—a Lord World where beings from countless races and factions fight for supremacy. Lords awaken on infinite continents with a single talent, tasked with forging empires from humble beginnings. The twist? The Supreme Empress and her council of 10 Major Beings (all female, just below cosmic power) observe from the shadows, seeking a successor to rule the cosmos. Magic thrums beneath the surface, invisible to the weak, while ancient factions—elves, dragons, humans, and more—wield vast advantages. Kael El, an Earth transmigrator, steps into this chaos with two unparalleled talents, his sights set on total domination.Power System OverviewThe Lord System rules all: each lord gains one talent at birth (F to SSS, S+ being unique), driving exponential growth through conquest and kingdom upgrades. Kael’s talents—SSS: 100% Drop Rate (every loot drops, from talents to bloodlines) and EX: 10,000x Drop Multiplier (boosts quality or quantity per item, including summons)—shatter the system’s limits. Stats (Strength, Speed, Aura/Magic) scale across Three Planes of Existence: Mortal Ascension (Initiate to Infinite Lord), Universal Mastery (Universe to Omniversal Architect), and Void Transcendence (Void Seeker to Nihility Incarnate). Kingdom levels cap a lord’s potential (e.g., Territory Lv. 2 limits Kael to Mighty Lord, Lv. 30), unlocking higher tiers via rank-specific conditions. Subordinates benefit from loot, fueling Kael’s rise.MC’s Starting PointKael El awakens on a modest plot, Territory Lv. 1, with a rickety hut (upgradable), basic resources, and food for 8 days—no Summoning Altar yet. A former Earth gamer, he’s chill yet relentless, radiating unwavering confidence and a cool, dominant vibe. The 7-day peace period bars attacks on rival lords, forcing him to strategize with what he’s got. His 10,000x Drop Multiplier triggers on summons once unlocked, promising an explosive start. Calm under pressure and fiercely determined, Kael aims to build the ultimate kingdom, crush all rivals, and claim the cosmos, his flirty smirk hiding a “don’t mess with me” edge.

I, an ordinary high school student, Kimizuka Kimihiko, who easily gets involved in things, was appointed to take care of mysterious attache cases by mysterious men in black suits. After meeting a beautiful angel-like detective girl, named Siesta in a hijacked plane, I became her assistant.

And from there–

[You deal with the beehive, and I’ll restrain the enemy.] [Don’t make plans that make me the victim.]

We had those kinds of foolish conversations, all while being completely broke every day and fought against . Even when there were hurricanes, the weather-beaten duo sleep past it. Sometimes when we saved money at a casino, we would jump around on the beds at a resort hotel, only to be broke again the next day. We would walk through deserts, traverse through jungles, conquer mountains, cross oceans– The great detective and her assistant would go through these dazzling adventures–

Until she died.

And this story starts from 1 year after that incident.

I’m the only one who’s left, but I carry on her remained wishes.

This story is far from over..

Yuan Luoyi felt like she was a little hamster in a pit of snakes, with her family full of crazy villains, yet as the fake heiress she still focused on slacking off.

Dad was an arms dealer, Mom an ace assassin.

Eldest brother, business world’s killing god, with proxy syndrome.

Second brother, cold-blooded lawyer, zero moral sense.

Third brother, addicted to killing, born with antisocial personality.

Fourth brother, evil celebrity, who trained fans into believers.

Fifth brother, genius scholar, loves those pure white bones.

Yuan Luoyi didn’t know that because of her birth, the world gained five more brothers, not five more lunatics.

Those greedy villains also didn’t know, the one they wanted to kill was not an ordinary girl, but the most beloved little sister of five crazy bastard brothers.

The female lead has 99 lifetimes of memories, a system, harem darling + suspense, happy ending.
