During the days when Lette temporarily left the Demon Realm, the mice were very bored.
Because Lette gave them orders when he left, the entire Supreme Spiral Company was unable to continue advancing further into the Abyss Plane.
The mice were essentially trapped within the first two hundred layers of planes, but because everyone knew that further advancement in the abyss exploration plan was needed, there were no restrictions on production capacity or population.
In fact, to better advance the plan and provide better feedback to the boss.
The mice held a spirit of determination at heart, continuously perfecting themselves.
Moreover, the Rat man Clan, for the first time ever, had its own Demon God.
This was an epic-level motivation for the mice.
Since Lette left, the Rat Demon Clan has been in an extremely excited state.
The only thing in their minds was self-optimization!
