Vandalieu succeeded in creating a virus to use in the war!

“It’s transmissible through air, across mucous membranes and through blood, and it takes effect within five seconds. Its symptoms are only violent nausea, headaches, dizziness, fevers, stomach pain and joint pain, so it takes several days to kill the target, and it will kill less than ten percent of those it infects. But I suppose this will do,” Vandalieu concluded.

Vandalieu nodded, looking at the Double-headed Tyrannosaurus that was lying on the ground with its tongue hanging out, creating a stain made of saliva, gastric juice and nasal mucus.

“… Bocchan, I think that’s plenty for an incurable disease,” said Rita.

“If this disease spread to the Mirg shield-nation and the Amid Empire, the nations would stop functioning,” said Saria.

“You’re right,” Vandalieu agreed. “But they have life-attribute mages and great priests of Alda, so it should be fine.”

“Treating diseases with magic is considerably difficult, and different spells are needed to cure different illnesses, so I believe it may not go so well,” said Sam.

“There are people who have the Disease Resistance skill and the Disease and Poison Resistance skill that offers resistance against both diseases and poison, but they’re quite rare,” Kachia added.

According to Sam and Kachia, neither the Amid Empire nor the Mirg shield-nation’s plans to deal with an epidemic were very sophisticated.
They knew of soaking affected parts in alcohol or hot water, but there were no antibiotics in this world. Potions, healing spells and resistance skills existed in their place, but as dealing with diseases went, they were imperfect.

Though there were Potions to treat diseases, they were expensive and didn’t work against all kinds of diseases. It was more commonplace to drink antidote Potions to neutralize toxins that had accumulated in the body to lessen the symptoms.

The development of healing spells was slow and they were not very advanced. Even if a cold was cured by increasing Vitality, using the same spell on a cancer patient would cause cancer cells to metastasize all over the body and cause the patient to die almost immediately.

Treating diseases with spells would be impossible without advancements in anatomy and physiology, knowledge of how the body works and how pathogens affect their hosts, and technological innovations.

As for resistance skills, few adventurers and knights possessed skills that granted resistance to disease. Most monsters possessed resistance to poison rather than disease, and assassins and mercenaries used poison rather than disease anyway. That was why Poison Resistance was fairly common, but Disease Resistance was rare.

Those with such weak constitutions that caused them to fall ill frequently enough to acquire resistance skills wouldn’t think to become adventurers.

“Have I created something unexpectedly dangerous?” Vandalieu wondered. “But I made it so that its effects will stop after half a day, so I guess it will be fine.”

Even if the disease did spread, there wouldn’t be any casualties since it stopped working in half a day, and with the population density in this world, it wouldn’t spread beyond a single village or town. If something unexpected did occur, Vandalieu would simply have to use brute force with his Mana, casting a wide-area Sterilization.

It was as Vandalieu was justifying the creation of the disease to himself with these excuses that Rita and Saria had come to have a look.
