Time is ticking, and it's been nearly a week since Cheese and the Sober reached an agreement. During this time, Cheese also offered to ask the Sober to help the proto-nezumi roaming Canyon not harm Heather and her troops, but he was told that the Hammer Knights led by Heather had been spotted and had left Canyone. Before the chief knight left, she used the paper she found in the city to write down the information she had received from the royal family of the Greylion Kingdom, and Heather spread the paper as much as possible throughout the city, so that the missing Cheese and Leon could have a chance to know what was going on outside. And this information did not disappoint Heather, and the day after she left, a sober person brought these pieces of paper with important information to the mage. Of course, this inevitably made the sober also aware of the kingdom's order to kill the inhabitants of the county of Salon, as well as all the nezumi.

Originally, Cheese and Leon were a little surprised by Heather's sudden departure, but when they saw the message left by the female knight chief, it was not difficult for them to understand Heather's choice.

"She's helping us stall for time. The Blood Lion said.

Heather left the county with the surviving members of the squad, ostensibly because he feared that the kill order would affect her. But Leon, who had worked with female knights, knew that things were not what they seemed. However, Cheese and Leon understand Heather's choice, while the others don't know the Lady Knight Captain so well, and they all express a little loss at Heather's departure. After all, hearing that the last friendly army in the county has left, it will feel a little betrayed by anyone.

"I heard you gave her the tools to find you before?" asked the Chief Knight of the Kingdom, indeed, Cheese had given Heather a carved wood owl that could find his place before parting ways.

"The prop could only find me from a flat surface, and I didn't expect to be tied to the ground. So she couldn't find this place with that prop in her hand. Spreading his hands, Cheese admitted that he had made it easier for him to think of the threat in Vale. But even if he asked the mage to do it again, I'm afraid he wouldn't believe that these nezumi had dug such a large space underground in such a short period of time.

"But at least she knows you're still alive, right?" Leon said.

Cheese thought about it, although Heather couldn't find this underground space, the wood carving could indeed allow the female knight to determine the approximate location of the mage. With Heather's ability, she could not have deduced that the mage was underground. So at least by the time Heather leaves Vale, she should be able to confirm that the mage is still alive. The mage nodded, agreeing with the Blood Lion's guess.

"That's right, I think Heather should have guessed that your life is not in danger for the time being, and at worst, you are just trapped there. The few days she spent in the city should have confirmed this. Leon said.

"But what does that mean? I mean, even if Miss Heather knew that Cheese was alive, she would be able to leave with confidence?" asked Mona, the warriorwoman who did not understand the connection between the two events.

"She's not leaving, as Mr. Lyon said before, Heather is there to buy us time. Cheese said.

"Since it has been confirmed that I am not in danger for the time being, and she has no way to approach the place where I am, in fact, the continued activities of the Knights of the Hammer in Vale City only increase the risk of their own casualties. Instead, it is better to return to the border first, explain the situation to the people of the kingdom, and if not get the king to withdraw the killing order, at least she can delay the entry of the clearing troops who have entered the county. ”

"But what's the use of delaying the entry of those troops, they'll all be in the county sooner or later, anyway. ”

"But then we have a chance to develop an antidote to the nezumi state or something else that proves that the plague can be suppressed, so that we have a chance to give these people a chance to live. Gloria understood what the mage meant, and she replied with Cheese's words.

"Then it looks like we're going to pick things up. I don't think Heather would have been able to delay much even if she tried her best. Elsa watched Cheese make her closing remarks. And with the words of the proprietress, everyone also focused on the mage, after all, the progress of the entire research was actually not helpful to others at all, and the interpretation of the rat-man plague could only be done by Cheese alone.

"Don't worry, I think there will be a preliminary result in the next two days. The mage said indifferently. Indeed, since the completion of the lab, Cheese has devoted almost all of his time to research, that is, the rat people are unwilling to give Heather's message to humans other than mages, otherwise Cheese will not stop the experiment to discuss it with everyone.

How did Leon sum up the mage's almost crazy research momentum.

"I've seen a lot of pretentious scholars and mysteries in my life, but I don't think even the hardest working students in the academy can go so crazy for academics. "Maybe it's because Cheese's look when he started his research was so focused that it was a little scary, and the Blood Lion couldn't find any other adjectives for a while, so he could only describe it as crazy. And his remark is a sentiment shared by anyone who has worked as an assistant to cheese in the lab.

Back in time, the eighth day of Cheese's journey underground, and the fourth day of Heather's departure from Vale, the mage walked out of the laboratory door for the first time, and beside him, stood Hal as a volunteer, the black-haired rat-man who led the sober.

"I have to say, Mr. Cheese, it's great to be able to please feel that pain. Because he was not yet familiar with the pronunciation of the nezumi organs, Hal spoke with a strange emphasis, just like Gloria had been. But when the sober man was able to speak again, everyone was impressed by what the mage had done.

However, only Gloria, as an assistant in this experiment, understood what Cheese had done, and the mage had done more than just a proto-rat stabilization operation in the past seven days, he had studied something extremely extraordinary.

"Gather all the sober ones together, and I will give each of them a gift. Although there were two distinct dark circles on his face, the mage's tone of voice was more excited than ever, and he waved the water bag sewn in sheepskin in his hand and shouted happily.

"What's wrong with him?" Leon asked Gloria, puzzled as only the Count's daughter, who had spent time with Ann Lina in the Grey Tower, could roughly guess what the mage was doing.

And perhaps the time was not right for the knight to ask, but Gloria, who had always been able to keep her calm, seemed as excited as cheese at this time, and there were even tears in her green eyes, the girl who was the first to ask for the pain caused by the rat-man plague said in a crying voice.

"And he succeeded...... He's made a potion that will stabilize the condition of the proto-nezukyan!"

Silence, then cheers, every human or awake person in the depths of the earth spread the news in their own language, Cheese, the mage from north of Dragonspine Mountain, who spent nearly a week cracking the plague lesions on the protonezumi, and in doing so, created a potion that would make the protonezu no longer infectious, and relieve the blood-eating impulses and mad instincts that came with it. As long as time is given and every nezumi drinks this potion, then the spread of the plague will be greatly weakened, and the existence of the nezumi will no longer pose a threat to other uninfected people! The kingdom can also give these infected people more time, and they can even find a way to restore the nezumi back to humans in the future! In a sense, this plague has ushered in the first light of its end at this moment!

At least for now, everybody here believes so.
