Myriad Worlds: From the Start, I Offended Madam Ma and Became Invincible

[Feel-good power fantasy + Myriad Heavens + System + invincible hero + multiple heroines + transmigration in the flesh.]

Lin Beixuan accidentally transmigrates into Demi-Gods and Semi-Devils. From the start, he talks back to Madam Ma and activates the Myriad Heavens System, gaining invincible cultivation. An ordinary loser instantly becomes a “max-level powerhouse,” with bottomless inner energy and the ability to master any martial art at a glance. From then on, he begins his peak life as a domineering hero.

But the System tells him: “Invincible? Sure! Want to leave? Not so fast! In every world, you must complete a randomly assigned System mission before you can unlock the next stop.”

Mission One: What? You want me to spend five years as a Shaolin disciple?

No problem. Secular disciples count as Shaolin disciples, and even the abbot's junior brother is a disciple.

Mission Two: What? You want me to show off with style in front of the Five Greats at the Mount Hua Swordsmanship Contest?

I'm good at that. Behold, my Great Creation Palm…

Mission Three: What? You want me to shave Old Celestial Master bald?

Wait, I don't know how to cut hair… Fine! Now Old Celestial Master really is at the very peak.

…

Lin Beixuan completes one bizarre System mission after another, wandering the myriad heavens, living freely among them, and reigning supreme across them all.

No hero in the world can withstand a single move from Lin Beixuan, and no woman can resist his smile.

“Pine winds stir the shadows of swords, the cold moon shines on my chill robes. A fierce roar startles the forested hills, a long song carries into Beixuan.”

I am Lin Beixuan!

P.S. This story has multiple heroines. If you're already invincible, why not chase women? Unless you'd rather chase pickles?
