Sanbo Hospital, the Laboratory and Ruixing Company together form a complete chain. With a complete chain, developing a set of reagents targeting K Virus antibodies is not difficult, for the methods of detecting antibodies are all quite similar, and can be realized with minor modifications.
Indeed, K Virus antibodies were detected in Sisi's body. After multiple injections of the K Virus in Sisi's body, it engaged in numerous confrontations with the human immune system, which enabled the immune system to find a method to counter it, activating certain immunocytes and producing corresponding antibodies. The activation of immunocytes and the generation of antibodies resulted in the K Virus being killed shortly after it was injected into the body.
Increasing the injection dosage is one method, but there is a limit to this. Indiscriminately increasing the virus injection amount can easily over-activate the immune system, causing the body to collapse due to an excessive immune response.
