King Graves' plan was no problem, and Svadia was attacked by the four kingdoms, and the main army went north to defend against the enemy. King Greyfus mobilized the forces of the nobles in the kingdom and launched a large-scale attack to the north. They reclaimed Viruga, who had been deliberately abandoned, and fought all the way back to Fort Gruenward.

Originally, Rhodok's army had an absolute advantage, and they were also very familiar with the city defenses of Fort Gruenward. Originally, it was only a matter of time before they captured it, and it was only a matter of time before they went north to besiege Fort Wincord, or even to attack Uxhall. But there are unforeseen circumstances, and who would have thought that there would be a sudden plague in the army.

Some say that the plague came from dead bodies that had not been properly disposed of during the war, while others said that the plague came from a band of northern bandits who called themselves the Brotherhood, who were horribly killed by the dead beasts thrown by the attackers and the rats that raged in the camp during a siege, and those who escaped were infected with diseases that could flare up at any time. They had been hired by the Rhodoc army, but they all fell ill and died before long.

Regardless, the plague destroyed half of the army's combat strength, forcing the nobles to retreat.

When the sick soldiers returned to Viruga, the plague began to spread in the villages and cities they passed, mainly by local prostitutes. In just two weeks, the plague spread to Fort Gruenward, and more than 20,000 people were infected throughout the South!

The plague was contained in the cities, but it continued to spread among the poorer villages, spreading in both north and south directions through the flow of refugees.

When the plague spread to Serindil, Byron immediately placed martial law on the town, quarantined the sick, and asked everyone to take care of their personal hygiene. James agreed, praising Byron's ability to use his knowledge.

James then immediately examined the patients, he checked their symptoms, and consulted a lot of medical texts, and finally told Byron very seriously that this was the "death disease" that spread throughout the empire in the late period of the ancient Calard Empire, and caused the population of Calradia to drop by one-ninth, which is the famous "Black Death" in the world in the world of Earth Europe!

Fortunately, although the late ancient Carard Empire had begun to divide internally and chaos led to the spread of death, people's minds were much more enlightened than those of the European Middle Ages. Academic research is well developed, and there is no church to interfere. So after a large number of patients died, scholars and doctors risked their lives to find out that the germ was transmitted by rats, and developed a cure for the disease to a certain extent.

It is said that after the cure came out, almost everyone in the upper class of the Kallad Empire had a cat, the streets and alleys were full of wooden barrels for people to wash their bodies, and the business of bathhouses was so good that there was even a cult that used dead mice to worship the cat god.

Now that there are precedents to follow, James' job is much simpler. Although the classics of the past were largely destroyed and lost due to the war, he still used the large amount of herbs he had stored before to make medicines that could cure diseases. Of course, it wasn't entirely easy, and there were always one or two dead or injured in ten people, but it was very successful in this era.

In terms of sanitation, Byron also did as the Kallad Empire had done, mobilizing soldiers and civilians to eliminate rats, improving sanitation, digging drainage canals outside the town, and building more hygienic public toilets.

Because of the series of evil consequences caused by this plague, King Griffos was frantically complained by the domestic nobles, and had no choice but to negotiate peace with Svadia, and the two sides ceased war for no less than six months.

Byron's security was assured, and the border between the two sides was not completely impassable. Byron purchased large quantities of herbs to produce medicines for the plague, which were sent to the plague-stricken southern parts of Swadia and to the kingdom of Rhodok.

Not every person who studies medicine can figure out how to make drugs in a short period of time like James did, and not every doctor can stock up on drugs in such a short period of time to produce drugs. For those who also see business opportunities, it is much more cost-effective to buy drugs directly from Byron and sell them at a high price than to develop and produce them themselves.

Within a month, Serindil had become almost a large pharmacy, with thousands of copies being produced and sold for 5 dinars each. In the hands of some Rhodok merchants, these drugs could be sold for 10 or even 15 dinars, and they were sold without worry. After all, there are people who are sick, and a medicine may not cure him.

In fact, Byron's original idea was also to take advantage of the plague to make a fortune for 10 dinars a medicine. But this was strongly opposed by the three heroes of the good guys, Fatis, Jamila and James. Although he didn't say it explicitly, Byron could confirm that Kenrad and Alleyne were also with them. Even at his request, Byron had no choice but to send people to sell drugs directly to avoid inflating prices, and to provide free medical care to the refugees who came to Serindil.

This made Byron earn tens of thousands of dinars less, and his mood naturally would not be very beautiful. However, this did improve Byron's reputation in the newly occupied land, and the former Serindil people began to return, along with a large number of sick refugees.

After James healed them, they stayed with gratitude to James and the others and Byron, and there were some talented people who hoped to be loyal to Byron and find a job with Byron.

A month later, while the people of Rhodok were still battling the plague, the area under Swadia's control had been brought under control by the special price delivered by Byron and even the free medicine that Jamila had secretly smuggled.

The population of Serindil had risen to four or five hundred, and all kinds of jobs were done, and even the bathhouse prostitutes had returned. Byron's popularity rose by 30, and when he went out, the inhabitants saluted him respectfully, and the streets regained their life.

Jamila was very pleased with this, and called Byron an enlightened lord, and Phatis praised Byron for his kindness. Of course, they didn't know that beneath Byron's smiling face was a heart that hurt to the core.

James already had a certain reputation in the South, and after this incident, his reputation became even more famous, and even some medical seekers were willing to travel hundreds of miles to Serindil to seek medical treatment, and some medical students came to learn the arts. This has helped to some extent in the development of Selene Deere's medical technology, and Byron is pleased to see the expansion of his medical team.

In the midst of this plague, Byron became the winner. The enemy retreated to ensure his safety, and he earned more than 20,000 dinars by selling medicines (of course, Byron made a lot of money by raising the price of the drugs sold to Rhodok without the heroes). While the other lords had lost their fortunes in exchange for safety, he took advantage of this opportunity to grow his own power.
