A fatal virus, colorless and odorless.
When it was developed, researchers conducted numerous studies and experiments to make the virus more transmissible.
It underwent many improvements and optimizations.
The current Sakuragi Hana virus can certainly be called the strongest virus in human history.
Once outside a human or animal body, it can spread through media such as dust, airborne particles, and water vapor.
And it can survive effectively for up to a week.
This also means that
if someone is infected with the Sakuragi Hana virus, they must be quarantined and observed for at least a week before it can be confirmed whether they are infected.
And now...
The heavily guarded research base had its gates wide open.
High-pressure atomization of a large concentration of antiviral and sterilizing agents, like smoke, enveloped the base's only entrance and exit.
This way, the Sakuragi Hana virus wouldn't drift out and spread into the outside world.
But what about inside the base?
