Dragon Ball: I Have a Time Simulator

[No progressing alongside the original protagonist, Saiyan Empire, simulator, ensemble cast, invincible at certain stages, mostly slow-paced, multiple heroines (including Android 18), altered plot, numerical power levels, few battle scenes, progression-focused, multiple timelines]

[Frequent simulations before the Trial of the Gods; almost none afterward]

This is the story of a high-class warrior with an overpowered cheat who leads the Saiyans step by step toward greatness.

Just an ordinary novel with a lackluster synopsis. Please head over to the story itself.

P.S.:

Cheat ability: The protagonist has a simulator, with each simulation lasting a maximum of four months.

This novel's Saiyan mechanics: Every Saiyan transformation tier has a limit, and each tier has a different training rate.

For example:

Before the protagonist can become a Super Saiyan, one day of regular training under 1× Saiyan gravity increases his power level by 50;

After unlocking Super Saiyan 1, one day of regular training under 1× Saiyan gravity increases his power level by 2,500;

Super Saiyan 2: +5,000;

Super Saiyan 3: +20,000;

Black-Haired Super Saiyan 4: +200,000.

Examples of the protagonist's maximum base-form power level at each transformation tier:

Before unlocking Super Saiyan: Maximum base-form power level of 17 million;

Super Saiyan 1: Maximum base-form power level of 850 million;

Super Saiyan 2: Maximum base-form power level of 42.5 billion;

Black-Haired Super Saiyan 4: Maximum base-form power level of ∞;

However, these mechanics do not apply to hybrid Saiyans or Saiyans of royal blood. I won't go into detail here-read the story to find out.

If you can't accept this novel's fan-created mechanics, feel free to peacefully move on after reading the synopsis.
