Viruses, the smallest and simplest of organisms, could silently destroy the bodies of all kinds of living creatures.
They were deadly weapons invisible to the naked eye.
During their journey across the Dark Continent, Moyu and the others had once seen a giant bird several times larger than a passenger plane slowly descend from the sky, then struggle and die on the ground, its feathers falling out at a visible rate.
Only after Sambika examined it did they learn that the giant bird had died from a viral infection...
That showed just how vicious the Dark Continent's viruses were. They could pose a lethal threat even to predators that ran rampant throughout the food chain.
But Moyu wasn't sure whether the viruses Sambika had collected and studied could threaten Liu Yin.
Now—
He had simply delivered the virus into Liu Yin's body. All he could do next was wait.
Just as he waited for Kyoka Suigetsu to bear fruit, he had to wait for the virus to overwhelm Liu Yin's body.
But he didn't know how long that would take.
By conventional wisdom, a virus always needed some time between invading a body and running rampant.
That would definitely take longer than Kyoka Suigetsu's five minutes.
But this virus from the Dark Continent might prove powerful enough to defy common sense.

And because Liu Yin understood the common tongue, Moyu couldn't tell Biscuit and the others about it in front of him.
"Kanzai, Hisoka, Bis... Sis."
