My Chip that Disguises Itself as a Cell

Lairs have four major benefits for humans.

The first benefit: the lair site can be developed for agriculture, livestock, and fishery. The products contain special energy that can be easily absorbed by humans.

The second benefit: the lair comes with a variety of monsters. The bodies of these monsters contain special energy and can be processed into various items.

The third benefit: the lair comes with a variety of heavenly treasures. This natural treasure can improve human qualifications and have a chance to let the person taking it to develop skills. The most important thing is that any difficult disease can be cured if you find the right natural treasure.

The fourth benefit: is skill crystals. They almost could not be found in first-class lairs. They are likely to exist in the body of the second-class lair master. They are likely to exist in the body of third-class epic monsters. The higher the level, the more skill crystals will be produced.

But again, the higher the lair level, the more difficult it is to beat it.
But all of this seems to become a minor problem for me who has turned into a brain cell chip.
