[Lord of the Mysteries] Reborn as the Celestial Worthy, I Cling to My Successor

The main goals: Keep little Klein company, since he's been lonely from beginning to end; give him a golden finger so he can easily resist corruption and hold on to his humanity; and save as many characters as possible whose tragic fates left us heartbroken (Dunn and Daly, Old Neil, the Great Smog, etc.).

A little point to remember:

The protagonist truly transmigrates into a book. After the ending, he travels back and forth between his hometown and the world of mysteries, and even brings the homesick group back home to slurp noodles.

An absurdly overpowered cheat turns the Lord of Mysteries' murmurs into a hometown pal's casual chatter.

The protagonist is always on little Klein's side. Their interests are completely aligned in the early stages. Later, the protagonist is an angel under the Fool according to the holy scriptures (if you're a Curly-Haired Baboon, then you're going to embarrass yourself together!). In reality, his stature and power are about on par with the Lord of Mysteries (you could think of him as half of the Lord of Mysteries?).

A (not at all) serious introduction:

I woke up in the world of mysteries and opened my eyes to see...

That the source of the corruption was me.

The transmigrator Zhou Jingyu opened his eyes and saw a world shrouded in gray mist. A few days later, every Seer on the continent heard a new murmur:

Steamed lamb, steamed bear paw, steamed venison tail, roast duck, roast goose, braised pork, braised duck, soy-braised chicken, cured meat...

Zhou Mingrui, who had just arrived: ...

Zhou Jingyu, who had accidentally muttered in his sleep: ...

Stop calling out, stop calling out! You're going to lose control!

Years later, the true gods across the continent discover that the Lord of the Mysteries, Klein, is always in good shape and never loses control. Meanwhile, the (former) Lord of Mysteries himself smiles quietly, taking no credit.

I'm the source of the corruption, and even I can't cure your mental illness?

Those who should have died offer the Fool their highest praise. Those who should have suffered set out early to pursue their ideals. Those who should have despaired find a light to hold on to in the darkness...

Because from the very beginning of the story, the greatest enemy had already switched sides, steering the massive ship sailing along the edge of a cliff toward its destined happy ending.

Theme: Stick close! Stick together until the very end!
