Reborn with a Disciple-Acquisition System

The Protagonist Is an Older Man or an Elderly Person, Anything but a Teenager

Every protagonist in Tomato's novels seems to be a young man, and I'm getting tired of it. Are there any novels with a tough older guy as the protagonist? Any genre is fine, though a realistic post-apocalyptic setting would be ideal. 🤔

System! System! System! System Novels!!!

System novels, System novels.

The Protagonist Gets Stronger by Taking on Disciples, with No Romantic Subplots

[Most important: no female lead! No romantic pairing! No ambiguity!] Ideally, the protagonist has limited aptitude and cannot reach a higher level, so they use a System to recruit talented disciples and then become stronger. It's fine if this isn't included.

The Protagonist Is a Sect Elder Stronger Than the Sect Leader, and Takes on Disciples

An Invincible Master Who Takes on Disciples Everywhere, Complete and Never on Hiatus

The master should be invincible from beginning to end, then take on disciples. I want a completed story, completed, completed, with no hiatuses. Don’t recommend abandoned or ongoing series.
