Fullmetal Alchemist: This Time, I'll Guide My Brother in Cultivation

"Brother, you used alchemy to bring me back. What can I give you in return?"

A'er traveled far to the New Kingdom to study elixir-making for three years, only to break a prohibition while saving someone and be expelled from his sect.

Everyone laughed that without the Elixir King's protection, he would never amount to anything. But with his alchemical analysis and Chaos Flame, he braved ice caves, claimed strange flames, formed golden pills, and ultimately reached the Nascent Soul realm.

Yet the farther he went, the more clearly he understood one thing: no matter how precious the elixir, it could never help his brother cultivate.

Years later, Edward, who had lost his alchemy, stared in bewilderment at the cultivation manual his younger brother handed him.

"Can I really start over without the Gate of Truth?"
