They just don't get it the blue stone is the space stone which is not suitable for healing stuff. While the red stone is the reality stone which can bend reality.

Did that woman call upon the power of Tsathogghua to replenish the plant?

onee-chan we gotta collect all the infinity stones

@Samhill The other girl mentioned the inferiority of the stones she handed out for testing. I'm leaning more towards this reasoning than different functions of stones.

i love this manga for its good content

A new slave to be added then.

Noice.

@colxeric Because the stones are two different colors they do two different things?

Something tells me aliens are involved, don't quote me on that.

Is it implied that brother used his own powers, or the power of a powerful stone in his pocket, to hyper-grow the plant?

This is actually relatable to the gacha theme

I am not sure that the brother is completely human, those eyes...

Loved it, thanks for the update.

Can't wait for things to get real crazy🤣
