This is why they needed bat in Wuhan, for their toxic bacteria dung to harvest beetles which thrive on bat dung. Their shells are impervious to almost all OTC and pharmaceutical remedies. Through gain of function, they have weaponized beetle larva into a substance that recolonizes when introduced to moisture and living tissue then after it usurps it then turns back to an impervious fossil which many call cancer. They also use radiation weapons on targeted individuals to help incubate the microbes.
