Wayne: "But once you get vaccinated, the results will be completely different."

The assistant took out a glass tube about the length of a palm from a box filled with cold air.

A pale blue liquid was flowing in the glass tube; it was somewhat viscous and looked rather eerie.

A drop of pale blue liquid was taken from a glass tube, diluted, and injected into the mouse's body. The mouse was then thrown into a sealed jar containing necrotic parasites.

The parasites have once again burrowed into the mouse's body.

However, to everyone's surprise, amidst the rats' mournful cries, the undead parasites struggled to emerge from their bodies once more.

As if poisoned, the necrotic parasites writhed and twisted violently inside the jar.

After about ten seconds, the parasite's movements gradually slowed down, and finally it stopped moving altogether.

Upon seeing this, Cumberland's eyes widened: "This is..."

Wayne then ordered his assistants to throw vaccinated cats, dogs, and other live animals into sealed containers, which naturally resulted in the death of the parasites.

Cumberland exclaimed with delight, "With this, we'll never have to worry about anything on the battlefield again!"

Wayne: "Not only the city's residents, but all other living creatures, such as cattle, sheep, and pets like cats and dogs, need to be vaccinated. That's why I said time is of the essence... cough cough cough..."

As Cumberland walked out of the tent, he shouted, "Pass down the order: everyone must come to the square immediately! Everyone must be vaccinated right now, and no one can disobey!"

Watching the old knight's departing figure, Wayne, who was coughing incessantly, casually picked up a handkerchief and covered his mouth.

Once his breathing had calmed down a bit, the weakened Wayne picked up the handkerchief and glanced at it.

The vivid, glaring blood red made Wayne laugh weakly, and he slowly closed his eyes.

"Your Majesty, I'm sorry..."
