章 351: The Temporary Laboratory

"Who knows how long it would take for this demon-hunting expedition."

Grimm mumbled to himself.

Normally, the average duration for a demon-hunting expedition was between seventy to a hundred and twenty years. At least it was how long it would take for a normal demon hunter to complete his normal demon-hunting mission.

Not to discount that some worlds which had special rules of the world, or some out of the ordinary Stigmata Sorcerer would reduce or delay the duration of the expedition.

"It's going to take a hundred and fifty years at least!"

The Myna chipped in. "The sorcerers of ancient times would take a few centuries to pillage the world completely before abandoning them. Although this Black Isotta had some modern influence, he's obviously a conservative when it comes to the nature of full pillage."

"A full pillage? Are you saying that the Black Isotta is going to ransack the whole Burrow World dry?" Grimm asked in astonishment.
