Why do hermits keep prisoners in the basement?

First of all, our survivor "Web" was imprisoned in this basement!

Everyone knows that Tiao was a genius when he was not imprisoned, but after he was imprisoned, he even worked for the design of the manor every day besides being flesh and blood ~

(and combined with the skills of "Web", it can be inferred that he is doing the circuit construction and maintenance of the whole manor. )

Just for some reason, our survivor, the viper, escaped, but the viper is actually a poisonous snake. Does it have anything to do with our supervisor "Dream Witch"?

Let's put these aside for a while. In fact, this "mysterious basement" is a veritable "experimental base" besides holding "prisoners"!

Because "Mad Eye" not only created a "nation" that worked for itself, but also took our "evil lizard" as the experimental object!

And in the early days of the exposure of the "evil lizard", we also saw the "mechanic" tied to the chair. Is this plot carefully designed by the manor owner to turn these survivors into their own experimental objects one by one?
